[0029] The mobile clamp block 220 cooperates with the fixed clamp block 210 to clamp the clamping plate, and the left and right movement of the mobile clamp block 220 can clamp clamping plates of different specifications.

[0030] The mobile clamp block 220 shields the closing plate 270, so as to improve the appearance of the product and avoid the assembly opening 260 from being exposed and affecting the appearance of the product.

[0031] Under the action of the first locking bolt 230, the mobile clamp block 220 is pushed to move towards the fixed clamp block 210. When the first locking bolt 230 is loosened, the mobile clamp block 220 has a space to move away from the fixed clamp block 210, and under the action of the elastic member 222, the mobile clamp block 220 is pushed to move away from the fixed clamp block 210.

[0032] Referring to Figure 2 The base 10 is provided with a stud connecting piece 140, the indexing adjusting seat 20 is provided with a second sunken table hole 250, the main shaft bolt 70 is rotatably arranged in the second sunken table hole 250, the main shaft bolt 70 is threadedly connected with the stud connecting piece 140, and the main shaft bolt 70, the stud connecting piece 140 and the annular track cavity 40 are coaxially arranged.

[0033] In the utility model, when the indexing adjusting seat 20 rotates relative to the base 10, the indexing adjusting seat 20 rotates with the main shaft bolt 70 as the axis, and at the same time, the annular track cavity 40 cooperates with the rotating ball 410 to enhance the rotation stability of the indexing adjusting seat and the base, so that the eccentricity or rotation interference of the two is prevented, and the problem of damage of parts is solved.

[0034] Referring to Figures 4-6, the bottom of the rotating fitting cavity 110 is provided with a plurality of annular indexing track grooves 120, and a plurality of positioning grooves 130 are arranged in the annular indexing track grooves 120 in a circumferential direction; the rotating fitting part 200 is provided with an installation cavity 201 which is open on the lower side, the installation cavity 201 is rotatably provided with a rotating piece 310, the lower end of the rotating piece 310 is fixedly connected with an eccentric swing rod 330, one side of the installation cavity 201 is provided with an arc track groove 202, the eccentric swing rod 330 is provided with an elastic positioning piece 350 which is used for being movably inserted into any annular indexing track groove 120, the upper part of the installation cavity 201 is provided with a through groove 240 which penetrates the indexing adjusting seat 20 to the outside, the rotating piece 310 is fixedly connected with an adjusting lever 320, and the adjusting lever 320 extends to the outside of the indexing adjusting seat 20 through the through groove 240.
