A second mounting member 8 is installed on the outer wall of one group of mounting blocks, and a groove is provided on the end face of the second mounting member 8. The second spring 9 fixedly installed in the groove corresponds to the hole position on the mounting block. Another group of mounting blocks is provided with a rectangular hole, and the clamping arm 2 is provided with a rotation groove 23 corresponding to the hole position and matching the size. The other side of the clamping arm 2 is provided with a limiting groove 24 connected to the rotation groove 23, and the limiting groove 24 is adapted to the rectangular hole. The above-mentioned adjusting member 10 is The first section is cylindrical and the other section is square. The cylindrical shape is matched with the rotating groove 23, and the outward end of the cylindrical shape is connected to the second spring 9, and the square shape is connected to the limit groove 24 and the rectangular hole. The second spring 9 is a tension spring. Therefore, when the present design is in use, a pull block is provided at the outward end of the square shape. The pull block is pulled to drive the adjusting member 10 to move outward, so that the square shape comes out of the rectangular hole, and the limit between the clamping arm 2 and the mounting block is released, thereby realizing the flipping of the clamping arm 2 angle, so that the clamping arm 2 can complete the purpose of adjusting the state according to the specifications of the workpiece, thereby improving the scope of application of the present design.

[0025] The working principle of the utility model is as follows: by pulling the adjusting member 10, the adjusting member 10 is moved outward, and the block shape of the adjusting member 10 is completely removed from the limiting groove 24 of the clamping arm 2. During this process, the adjusting member 10 is connected with the second spring 9 in the second mounting member 8 through the cylindrical shape, and the second spring 9 is pulled, and then the clamping arm 2 is flipped, and the clamping arm 2 rotates with the cylindrical shape of the adjusting member 10 and the rotating groove 23 as the center. After the rotation is completed, the adjusting member 10 is released, and under the action of the second spring 9, the adjusting member 10 is pulled back, so that the block shape is reconnected with the limiting groove 24 and the rectangular hole, and the state switching of the clamping arm 2 and the mounting block is completed; Then pull the pull piece 5, which moves in the first mounting piece 4 and is gradually pulled out from the through hole 41. When the pull piece 5 is pulled outward, the auxiliary piece 6 is driven to move outward and squeeze the first spring 7. When the auxiliary piece 6 moves outward, its end portion leaves the positioning hole 31 of the auxiliary arm 3, releasing the limit on the auxiliary arm 3, and then the auxiliary arm 3 is flipped out of the storage hole 21. After the flipping is completed, release the pull piece 5, and under the action of the first spring 7, the auxiliary piece 6 returns to the top, passes through the through hole 22, and is inserted into the positioning hole 31; then, with the assistance of the driving mechanism and the slide rail, the slider 1 is controlled to adjust the spacing on the mounting plate.
