[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the workpiece to be processed is placed in the placement groove between two adjacent tooling blocks. The operator turns the bolt with a wrench to make the bottom of the bolt engage with the bolt hole opened inside the rectangular groove. The bolt presses down the pressure block through the countersunk groove opened on the pressure block. As the pressure block moves downward, the two first inclined surfaces fit with the second inclined surfaces inside the bidirectional side clamping plate. While the bidirectional side clamping plate moves downward, the two side plates also extend outward to achieve the clamping effect on the workpiece in the placement groove.

[0017] 2. In this utility model, after positioning is completed, the workpieces on the tooling blocks are adjusted to the same state through the adjustment mechanism, and then the workpieces are processed by the processing equipment. During the processing, when the processing angle of the workpiece cannot meet the processing requirements of the processing tool, the turntable in the adjustment mechanism is deflected at a certain angle through the drive device, thereby meeting the processing requirements of the tool. When the turntable rotates, the workpieces between multiple tooling blocks deflect synchronously, thereby effectively ensuring the processing accuracy of the workpieces.

[0018] 3. In this utility model, after processing is completed, the operator rotates the bolt to make the bottom of the bolt contact the bolt hole. At this time, the spring squeezed by the bidirectional side clamping plate rebounds upward, which drives the bidirectional side clamping plate to move upward, thereby separating the bidirectional side clamping plate from the workpiece. This makes it easier for the operator to take out the processed workpiece placed in the slot for replacement, thus improving production efficiency. Attached Figure Description
