In FIG. 2, reference numeral 5 denotes a motor for operating the vibrating head 6 and the hitting head 7 of the treatment section, which are provided in opposite directions for performing different operations, for example, massaging operations such as hitting and vibration. The motor 5 is fixed to a housing 8 made of aluminum or the like.

The motor 5 is connected to the output shaft 5 in two directions.
a, 5b, and one of the output shafts 5a has
A clutch holder 10 is provided which rotates via a first one-way clutch 9 which is engaged when the motor 5 rotates forward and idles when the motor 5 rotates reversely. A vibration head 6 that vibrates due to the rotation of the motor 5 is eccentrically provided on the output shaft 5a of the motor 5.

A worm 12 is fitted to the other output shaft 5b of the motor 5 through a second one-way clutch 11 which is fitted when the motor 5 rotates in the reverse direction and idles when the motor 5 rotates in the forward direction. This warm 1
A worm hole 13 which is rotated by the rotation of the worm 12 is meshed with 2. A cam 14 is fixed to the worm hole 13.
Of the push plate 15 is engaged with an engaging portion 15a formed at the end of the push plate 15 on the main body side.

Here, the push plate 15 is moved inward while compressing the coil spring 16 by the clockwise rotation of the cam 14 while being engaged with the tip of the cam 14, and the engagement is released. Then, when the coil spring 16 is opened, it moves to the outside of the main body. The push plate 15 is provided with a hitting head 7 that moves in conjunction with the linear movement of the push plate 15 in the left-right direction via a head drive shaft 7a.

On the other hand, a push switch section 17 is provided below the main body 1. This push switch unit 1
As shown in FIG. 3, a first push switch 18a for rotating the motor 5 in the forward direction and a second push switch 18b for rotating the motor 5 in the reverse direction are provided on the inner main body 1 side of 7. An actuator 19 that switches the rotation direction of the motor 5 by pressing the first push switch 18a or the second push switch 18b is provided on the inner grip 2 side.

The actuator 19 is slidably held by the housing 8 of the main body 1 so as to rotate the main body 1 at a predetermined angle, for example, 90 degrees, with the grip 2 coupled to the lower portion as a fulcrum. The grip 2 is provided upright on a flange portion 2b formed over the entire circumference at a distal end of a coupling portion 2a with the main body 1 provided at an upper end portion of the grip 2. The actuator 19 is configured to slide in the guide groove 20 and press one of the push switches 18a and 18b in accordance with the rotation of the main body 1.

Further, the push switch unit 17 is provided in FIG.
When the power switch 3 is turned on and the first push switch 18a is pressed by the actuator 19 (the second push switch 18b is turned off at this time), the motor 5 rotates forward. And the second

Is designed to rotate in reverse. In addition, 17a is a rectifier.

Next, the massage switching operation of the handy massage machine configured as described above will be described.

When the user desires a tapping massage, the user rotates the main body 1 so that the angle between the tapping head 7 and the grip portion 2 is 90 degrees or less as shown in FIG. At this time, the rotation of the main body 1 causes the actuator 19 to press the second push switch 18b, so that the push switch unit 17 is switched to the side for rotating the motor 5 in the reverse direction.

As a result, the second one-way clutch 11
The worm 12 is rotated through the worm hole 12, and the worm hole 13 is rotated by the rotation of the worm 12, and the cam 14 fixed to the worm hole 13 is rotated. The rotation of the cam 14 causes the push plate 15 to move inward while compressing the coil spring 16 in a state in which the push plate 15 is engaged with the tip of the cam 14.

Thereafter, the cam 14 further rotates, and the cam 14
When the distal end of the push plate 15 is disengaged from the engagement portion 15a of the push plate 15, the push plate 15 is moved outward by opening the coil spring 16. As a result, the tapping head 7 interlocking with the push plate 15 via the head drive shaft 7a makes a left-right linear motion, thereby performing a tapping massage.

On the other hand, when the user desires vibration massage, the user rotates the main body 1 so that the angle formed between the vibration head 6 and the grip portion 2 is 90 degrees or less as shown in FIG. . At this time, the rotation of the main body 1 causes the actuator 19 to press the first push switch 18a, so that the push switch section 17 is switched to the side for rotating the motor 5 forward.

Here, when the motor 5 rotates forward, the clutch holder 10 rotates via the first one-way clutch 11, and the vibration head 6 vibrates accordingly, thereby performing vibration massage.

As described above, by providing the massage changeover switch inside the main body 1, the massage can be changed over simply by rotating the main body.

[0024]

As described above, according to the present invention, by rotating the main body by a predetermined angle, the actuator provided at the joint between the main body and the grip portion reverses the first switch or the motor for rotating the motor forward. The rotation direction of the motor can be switched by pressing the second switch to be rotated. As described above, the switching of the massage operation can be performed only by the rotation of the main body, so that the massage by the desired treatment unit can be easily and reliably performed.
