In the outer peripheral surface of the first arm 2, a first finger hook portion 10 is provided near the first engagement portion 9. A first protrusion 9 a extending along the width direction of the first arm 2 is formed on an outer peripheral surface of the first engagement portion 9.

A first guide wall 9b is provided on one side edge of the first engagement portion 9 in the width direction (a side edge on the front side of the paper surface of FIG. 1) along the extending direction of the first arm 2. An arc-shaped first locking rib 21 is provided on one side edge in the width direction on the inner peripheral surface of the first arm 2 along the extending direction of the first arm 2, and the first locking rib 21 is provided. The rib 21 is continuous with the inner peripheral portion of the first guide wall 9b. A first contact portion 22 is protruded from an outer surface of the first guide wall 9b.

A second engaging portion 11 is provided at a third end 3a of the second arm 3 facing the first end 2a of the first arm 2. A second finger hook 13 is provided near the second engaging portion 11 on the outer peripheral surface of the second arm 3. A second protrusion 11 a extending along the width direction of the second arm 3 is formed on an inner peripheral surface of the second engagement portion 11.

A second guide wall 11b protrudes from one side edge of the second engaging portion 11 in the width direction (a side edge in front of the sheet of FIG. 1) along the extending direction of the second arm 3. . An arc-shaped second locking rib 23 is provided on one side edge in the width direction on the inner peripheral surface of the second arm 3 along the extending direction of the second arm 3, and the second locking rib 23 is provided. The rib 23 is continuous with the second guide wall 11b. On the outer surface of the second guide wall 11b, a second contact portion 24 is protruded so as to face the first contact portion 22 of the first arm 2.

The intermediate part between the first hinge part 7a and the second end 2b in the first arm 2 and the intermediate part between the second hinge part 8a and the fourth end 3b in the second arm 3 are made of a spring material. 12 are connected. The spring member 12 is formed of an arc-shaped leaf spring that is formed integrally with the base 1 and the like and that is convex toward the plate 5.

  The holder 101 in the state shown in FIG. 2 holds the water stopcock 102 with the first arm 2 and the second arm 3 in the states shown in FIGS. 6 and 8. That is, in the holder 101 in the state shown in FIG. 2, a portion near the neck 56 (see FIG. 8) of the water stopcock 102 is arranged between the first arm 2 and the second arm 3.

In this state, the water stopcock 102 is pressed against the second end 2b side of the first arm 2 and the fourth end 3b side of the second arm 3 so that the first arm 2 uses the first hinge portion 7a as a fulcrum. Further, the second arm 3 is tilted about the second hinge portion 8a as a fulcrum. At this time, the tilting of the first arm 2 and the second arm 3 can be assisted by using the first finger hook 10 and the second finger hook 13.

Therefore, as shown in FIGS. 6 and 8, the first end 2 a of the first arm 2 and the third end 3 a of the second arm 3 approach each other, and eventually the first protrusion of the first engagement portion 9. 9 a and the second protrusion 11 a of the second engagement portion 11 are snap-engaged, and the water stopcock 102 is sandwiched between the first arm 2 and the second arm 3.

  When the first arm 2 and the second arm 3 are tilted during the work of holding the water stopcock 102 by the holder 101, the spring material 12 is elastically deformed, and a reaction force is generated in a direction that hinders the tilting. This reaction force is applied in a direction to increase the engagement between the first projection 9a of the first engagement portion 9 and the second projection 11a of the second engagement portion 11, so that the first engagement portion 9 and the second Engagement with the engagement portion 11, that is, pinching of the water stopcock 102 is ensured.

  When the water stopcock 102 is strongly pressed against the first arm 2 and the second arm 3 during the work, the first arm 2 is closer to the second end 2b than the first hinge portion 7a. And the portion of the second arm 3 closer to the fourth end 3b than the second hinge portion 8a tends to deform greatly, and the second end 2b of the first arm 2 and the fourth end 3b of the second arm 3 The interval between the two tends to be excessively increased in part or all.

However, the spring member 12 separates a portion of the first arm 2 closer to the second end 2b than the first hinge portion 7a and a portion of the second arm 3 closer to the fourth end 3b than the second hinge portion 8a. Restrained. For this reason, it is possible to prevent the distance between the second end 2b of the first arm 2 and the fourth end 3b of the second arm 3 from becoming excessively large, and to stably hold the water stopcock 102 at a predetermined position. It becomes possible.

As shown in FIGS. 6, 8 and 9, when the holder 101 holds the water stopcock 102, the first arm 2 of the first arm 2 is held against the neck 56 of the water stopcock 102. The stop rib 21 and the first contact portion 22 and the second locking rib 23 and the second contact portion 24 of the second arm 3 face each other. The water stopcock 102 is arranged between the first arm 2 and the second arm 3 so that the water stop valve 102 is located between the first contact portion 22 and the second contact portion 24.

In this state, when the first arm 2 and the second arm 3 are tilted, the first locking rib 21 and the second locking rib 23 are positioned substantially on the same circle. The stop rib 21 and the second locking rib 23 and the step 52a of the first pipe joint 52 face each other before and after in the direction along the pipe axis L. Further, as the first arm 2 and the second arm 3 tilt, the first contact portion 22 and the second contact portion 24 approach each other, and the first contact portion 22 and the second contact portion 24 The abutted portion 54a of the water stopcock 102 is sandwiched between the stop valve 102 and the stop valve 54.

Therefore, the water stopcock 102 is along the pipe axis L with respect to the holder 101 by the step 52a of the water stopcock 102 abutting on the first locking rib 21 and the second locking rib 23 of the holder 101. The movement in the first direction (upward in FIG. 8) is restricted. Further, the water stopcock 102 is configured such that the outer peripheral surface of the operation portion 55 of the water stopcock 102 comes into contact with the first contact portion 22 and the second contact portion 24 of the holder 101, so that the pipe shaft with respect to the holder 101 is formed. Movement in the second direction (downward in FIG. 8) along the line L is opposite to the first direction.

The stopcock 102 is moved in the first direction about the pipe axis L with respect to the holder 101 by the contacted portion 54a of the stopcock 102 abutting on the first contact portion 22 of the holder 101. Is restricted. Further, the stopcock 102 is configured such that the abutted portion 54a of the stopcock 102 abuts on the second abutment portion 24 of the holder 101, so that the first stop centered on the pipe axis L with respect to the holder 101. Rotation in the second direction opposite to the direction is restricted.

  As described above, since the holder 101 can keep the posture of the held stopcock 102 constant, even if, for example, an external force is applied to the stopcock 102, the external force is not applied to the pipes 103 and 104. And the other pipe member is prevented from being twisted, bent, or strained. Further, even when the spindle 55a of the operation unit 55 is rotated to open and close the valve unit 54 of the water stopcock 102, the water stopcock 102 can be prevented from moving due to the operation force. Operation can be performed stably.

Also, as shown in FIGS. 1 and 4, when the first arm 2 and the second arm 3 are not engaged, the distance between the first contact portion 22 and the second contact portion 24 increases. ing. Therefore, when the contacted portion 54a of the water stopcock 102 is disposed between the first contact portion 22 and the second contact portion 24, the first contact portion 22 and the second contact portion 24 are obstructed. Can be prevented, and the workability of the water stopcock 102 is improved.

Note that when the water stopcock 102 is sandwiched by the holder 101, there is also an option to position the abutted portion 54a of the water stopcock 102 other than between the first contact portion 22 and the second contact portion 24. It is possible. If this selection is made, the rotation of the water stopcock 102 around the pipe axis L cannot be suppressed, but the orientation of the water stopcock 102 (the operation unit 55) around the pipe axis L is shown in FIG. It is no longer limited to the state. For example, depending on the construction conditions of the water supply, it may be necessary to prioritize the direction of the operation unit 55 over suppressing the rotation of the water stopcock 102. In such a case, if the selection is made, Good.
