The first slider 41 is further provided with a handle 47.

As shown in fig. 1 to 3, the positioning module 3 includes a second sliding block 31 and a taper material seat 32 connected to each other. The second slider 31 is also slidably mounted on the linear guide 2 below the first slider 41. The taper material seat 32 is provided with a taper through hole 33, the claw through holes 34 are distributed around the taper through hole 33, and the number of the claw through holes 34 is the same as that of the claw sheets 43. The tapered through hole 33 and the pressing shaft 42 are arranged concentrically. In this embodiment, the second sliding block 31 is L-shaped, and a horizontal plate thereof is provided with a through hole with a larger diameter, exposing the lower tapered through hole 33 and the claw through hole 34. The bottom end of the taper material seat 32 is provided with a positioning rib 321, and the positioning rib 321 is arranged along the edge of the taper through hole 33 and is used for being inserted into a part inner hole clamping groove in advance to position the rubber O-shaped ring.
