てられる。 Both covers 6a and 6b are assembled and caulked into pin holes 12 with pins 11 via collars 10, and the handle 9 is pivotally attached to the handles 9 so as to be swingable left and right. That is, the handle 9 has bifurcated branches 13a and 13b at the front end (left side in FIG. 1) of the pin hole 12.
The pin hole 12 and the branch part 13a, 1
3b, there is a slot 14 that is open only above the upper cover 6a in this embodiment, and a slot 14 is provided between the slot 14 and the inner surface of the upper cover 6a in this embodiment. An elastic body 15 made of a coil spring biased so as to be able to protrude and expand is embedded, and a sphere 16 is carried on the protrusion tip 15a of the elastic body 15. On the inner surface of one cover 6a, there is a concave groove 17 in the shape of a triangular pyramid into which the sphere 16 can be inserted.
a, 17b, and 17c are provided, and both covers 6a, 6b are assembled with the sphere 16 supported on the elastic body.
