Embodiment Construction
[0021] Such as figure 1 As shown, the figure includes a positioning claw 1, a sleeve 2 and a mechanism 3 that can move the sleeve 2 up and down and has a rotating device. The positioning claw 1 is connected to the front end of the sleeve 2, and the sleeve 2 can move along the positioning claw. The axis of 1 moves up and down. When the sleeve ② moves down, the claw of the positioning claw 1 will automatically tighten, that is, when the positioning claw opens, the broken end of the broken instrument is inserted into the hole of the positioning claw 1, and then the sleeve 2 is moved down, so that the positioning claw 1 The claws will be automatically tightened to lock the broken device, and then the mechanism 3 will rotate in the opposite direction to safely take out the broken device.
[0022] Such as figure 2 As shown, the positioning catch 1 is composed of an upper cylindrical part and a claw part. The claw part is in the shape of a drum as a whole, with a slot in the middl...
