[0004] However, the processing tooling in the above patent needs to disassemble the first clamping member and the second clamping member each time when in use, which is too cumbersome. The installation requires screwing many bolts, which increases the working time and reduces the working efficiency. Utility Model Content

[0008] Furthermore, the sliding assembly includes a slide rail laid on the top surface of the base, and a slide groove matching the slide rail is formed at the bottom of the first clamp.

[0009] Furthermore, the tops of both ends of the slide rail are connected to limit plates, and grooves for placing the limit plates are formed on the front and rear end surfaces of the first clamping member.

[0010] Furthermore, the bolt fixing assembly includes a bolt placed in the T-shaped hole, a spring is sleeved on the rod of the bolt close to the head, one end of the spring away from the bolt head is fixed to the inner wall of the T-shaped hole, and the other end of the bolt is threadedly connected to the T-shaped hole opened on the fixed clamping seat.

[0012] Furthermore, the first clamping member is in a rectangular parallelepiped shape, and two U-shaped second clamping holes are formed on the first clamping member, and the two second clamping holes correspond to the first clamping holes.

[0013] Furthermore, the second clamping member is in a T-shape, and both sides of the second clamping member that are in contact with the two workpieces are arc-shaped surfaces that fit the workpieces.

[0014] Compared with the prior art, the beneficial technical effects of the utility model are:

[0015] The utility model connects the first clamping part to the base by sliding the sliding assembly, so that the first clamping part and the second clamping part can be quickly docked with the fixed clamping seat, and the screwing of the bolt is reduced, thereby improving work efficiency. The spring is used to ensure that the bolt always stays in the T-shaped hole to prevent loss, facilitate locking, and further improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
