Referring to fig. 2 and 3, the single-group positioning mechanism 3 includes a base 31 mounted on an upper end surface of the table 1, at least one upright 32 mounted on the base 31, and a pressing plate 33 slidably disposed on the upright 32 in a vertical direction. The base 31 is provided in a long plate shape, the longitudinal extension direction of the base 31 is set in the horizontal direction, and the width direction of the base 31 extends in the direction close to the mounting base 11. The column 32 is disposed in a cylindrical shape, and an axis of the column 32 is disposed in a vertical direction and is parallel to an axis of the mounting base 11. In the present embodiment, the number of the pillars 32 in the single-group positioning mechanism 3 is two, and the two pillars 32 are spaced apart along the length direction of the base 31. The two upright posts 32 are slidably connected to the corresponding pressing plates 33 at the same time to limit the rotation of the pressing plates 33 so that the pressing plates 33 can only slide in the vertical direction.

In order to facilitate the assembly and disassembly between the upright column 32 and the base 31, the lower end of the upright column 32 is fixedly provided with a plug block 324, the plug block 324 is arranged in a cylindrical shape, the axis of the plug block 324 coincides with the axis of the upright column 32, and the diameter of the plug block 324 is slightly larger than that of the upright column 32. Correspondingly, the base 31 is provided with a plurality of insertion and extraction slots 311 for inserting and extracting the upright column 32, and all the insertion and extraction slots 311 are distributed at intervals along the length direction of the base 31. The cross section of the plugging slot 311 is circular, the axis of the plugging slot 311 coincides with the axis of the plugging block 324, and the plugging block 324 is clamped with the corresponding plugging slot 311.
