Conventionally, there are staplers that use small battery-powered electric motors, but the conventional ones are forced to slow down due to lack of power, so the needle extrusion blade cannot extrude the staples and staple the parts to be stapled quickly. Since chipping and the raising operation of the needle extrusion blade after the binding operation are performed sequentially, a waiting time is required for extrusion of the members to be bound, and therefore the operation is slow overall, which poses a problem in workability. ing.

Therefore, a striking body for downwardly striking the needle pushing blade, which pushes out the staples, is provided so as to be movable up and down, and this striking body is always supported upwardly.
During the binding operation, the impacting body is released from its energized support, and the impacting body is instantly lowered to force the needle pushing blade downward, and the needle pushing blade drives one of the staples into the member to be bound. There is something. In this case, if the striking body is moved up and down by an electric motor, even if the switch of the electric motor is opened, the electric motor will not be able to stop immediately due to its inertial force. Therefore, there is a problem that the impacting body moves to the next stapling operation.

Next, the operation of the above structure will be explained. When loading the stapler 21 into the needle storage case 20, when the release lever 45 is rotated outward, the rotation frame 43 is rotated clockwise around the support shaft 13. The locking protrusions 44 on both sides push up the locking rod 38 along its guide hole 19 against the spring 39. Then, the locking rod 38 separates from the locking step 36 formed on the protrusion 37 of the engaging piece 33, and the locking of the engaging piece 33 by the locking rod 38 is released, and the locking of the locking rod 38 is released. The pushing part 34 of the piece 33 is pushed by the actuating part 41 of the spring 39 which is rotated by the pushing up action of the locking rod 38, so that the needle to which this engaging piece 33 is attached is pushed. The storage case 20 is pushed out in front of the guide frame 12. If the degree of protrusion of the needle storage case 20 is small, grasp the knob 28 and pull out the necessary amount of needles from the guide frame 12 to insert a predetermined number of block-shaped staples 21 into the needle storage case 20. Set. Next, push the needle storage case 20 and attach it to the guide frame 1.

When the needle storage case 20 is pushed back even more forcefully, the locking rod 38 is gradually pushed up against the spring 39 by the guide edges 35 on both sides, and the needle storage case 20 is pushed back. At the same time as passing through the locking rod 38, the locking rod 38 is rotated downward by the restoring force of the spring 39 and falls into the locking step 36 of the protrusion 37 continuously formed on the guide edges 35 on both sides. Therefore, the needle storage case 20 is locked, and the needle push-out groove 20a of the needle storage case 20 is located directly below the needle push-out blade 54. Further, due to this, the stapler 21 in the needle storage case 20 is pushed toward the needle pushing groove 22a by the pushing action of the slider 24, which is constantly energized by the coil spring 26, and the stapler 21 is pushed toward the needle pushing groove 22a. 1, which is the cutting edge of 21

This switch lever 112 is rotated about a support shaft 114 as a fulcrum. As the switch lever 112 rotates, the interlocking piece 115 rotatably connected to the switch lever 112 is pulled forward against the coil spring 117. As the interlocking piece 115 moves forward, the pressing piece 118 formed at the intermediate portion of the interlocking piece 115 moves the movable contact piece 1 of the movable terminal piece 106.
09, the movable contact piece 109 is electrically connected to the fixed contact piece 104 of the fixed terminal piece 102, and the switch is closed. At the same time, as the interlocking piece 115 moves forward, the tip portion 124 of the stopper piece 120 attached to the rear end is disengaged from the rear side of the locking hole 125 of the machine frame 77, and this tip portion 124 When reaching the lower part of the locking recess 126, the coil spring 11
7 pulls the rear part of the interlocking piece 115 upward, so that the tip part 124 of the stopper piece 120
automatically fits into the locking recess 126, and the interlocking piece 1
The rearward return of switch 15 is locked, thus temporarily holding the switch closed.

When the above switch is closed, the electric motor 83 starts,
By the operation of this electric motor 83, a drive gear 89 meshed with this pinion 85 via a gear interlocking mechanism 86 is interlocked and driven, and a drive shaft 90 to which this drive gear 89 is fixed is driven. By this rotation of the drive shaft 90, the first disk 91 integrated with the drive gear 89 and the second disk 92 fixed to the drive shaft 90 are simultaneously rotated, and the first and second disks 91, 92 One interlocking locking rod 98 interposed between the rotating frame 6

2 is rotated about the rotation support rod 61 against the coil springs 82 on both sides, and the striking body 73 provided on the rotation frame 62 via the operating plate 71 is rotated upward greatly. Furthermore, by the upward rotation of the actuating plate 71, the elevating frame 47, which is connected via the coil spring 76, is slightly pulled up.
This elevating frame 47 and the guide frame 1 connected thereto via the locking protrusion 14 and the engaging protrusion 57
2 is rotated upward using the support shaft 13 as a fulcrum. When the interlocking locking rod 93 rotates, the interlocking locking rod 93 separates from the locking protrusion 68, and at the same time, the rotation frame 62 is moved through the actuating plate 71 by the return force of the coil springs 82 on both sides. is rotated back using the rotation support rod 61 as a fulcrum, and due to the forced downward rotation of the actuation plate 71 by the coil springs 82 on both sides, the striking body 73 of this actuation plate 71 is lowered, and the elevating frame 47 and Guide frame 1
2 is also rotated downward by its own weight, and the striking body 7
3, the tip of the lifting frame 47 is instantly hit hard. Then, the needle extrusion blade 54 vertically installed at the tip of the elevating frame 47 moves into the guide frame 12.

The members 132 are bent inwardly by the needles, and the member 132 to be bound is stitched by the needles. In the above case, the rotation of the drive shaft 90 rotates the cam disk 98 fixed to one end of the drive shaft 90, and the cam disk 98 is removed from the release recess 99 when the switch is closed. The pushing part 100 engages with the engaging protrusion 108 of the movable terminal piece 106, and the pushing part 100 pushes the engaging protrusion 108 to move the movable contact piece 109 against the fixed contact piece 104. Slides and rotates while maintaining the contact state.

Further, as the second disc 92 rotates, one of the switching rods 96 protruding from the second disc 92 presses and rotates the tip end portion 124 of the stopper piece 120 downward against the coil spring 117. ,
The tip portion 124 of this stopper piece 120 is removed from the locking recess 126 of the machine frame 77, and
The stopper piece 120 is pushed back into the locking hole 125 connected to the locking recess 126 and is locked to the rear side of the locking hole 125 by the return force of the coil spring 117. Also, with the return operation of the stopper piece 120, the interlocking piece 115 to which it is attached is pulled rearward by the coil spring 117, and the switch lever 112 connected to the interlocking piece 115 is moved backwards by the coil spring 117.
is rotated back around the support shaft 111, and its operating portion 113 moves forward of the guide groove 10 to prepare for the next operation. Further, due to the backward movement of the interlocking piece 115, the pressing support of the movable contact piece 109 by the pushing piece 118 protruding from the interlocking piece 115 is released, and the movable contact piece 109 is automatically separated from the fixed contact piece 104. The engaging protrusion 108 of the movable terminal piece 106 is disengaged from the pushing portion 100 of the cam disc 98 and engaged in the next release recess 99, and the switch is therefore automatically opened. Further, when the switch is opened, the movable contact piece 109 separated from the fixed contact piece 104 is automatically electrically connected to the contact piece 128 of the terminal plate 127. As a result, a counter electromotive force is generated in the electric motor 83 connected to the terminal plate 127, and the operation of the electric motor 83 by the inertial force is controlled, and the interlocking rotation of the drive gear 89 is instantly stopped by the braking action. As a result, the cam disk 98 does not rotate, so that the engagement protrusion 180 of the movable terminal piece 106 remains engaged in the release recess 99, and the pushing portion 100 engages the engagement protrusion 108. There is no need to push the

Then, one interlocking locking rod 93 separated from the locking protrusion 68 of the interlocking plate 66 and the other interlocking locking rod 93 on the opposite side engage with the inside of the engagement recess 67 of the interlocking plate 66. , to prepare for the next operation for interlocking the interlocking plate 66 in traction.

Further, the other switching lever 96 protruding from the second disc 92 is connected to the other interlocking locking rod 93 that pulls and interlocks the interlocking plate 66, and after the interlocking of the interlocking plate 66 is released, the tip of the stopper piece 120 part 12
The timing is shifted so as to push and move 4. That is, the interlocking locking rods 93 and the second disc 92 are arranged on both sides of the drive shaft 90.
