Specifically, as follows:

[0022] The mounting base 10 is further formed with a threaded hole 14, which is communicated with the accommodating groove 11 and vertically faces the limiting pressure receiving portion 111. Further, the pressing mechanism 20 comprises a pressing bolt 21 and a pressing block 22, the pressing bolt 21 is screwed into the threaded hole 14. The pressing block 22 is movably arranged in the accommodating groove 11 and is parallel to the limiting pressure receiving portion 111, the pressing bolt 21 abuts against one side of the pressing block 22 which is away from the limiting pressure receiving portion 111.

Then, the product 200 is placed between the limiting pressure receiving portion 111 and the pressing block 22, and the pressing bolt 21 is rotated to move towards the limiting pressure receiving portion 111, so that the pressing block 22 is pushed by the pressing bolt 21 to move towards the limiting pressure receiving portion 111 until the product 200 is clamped and fixed between the limiting pressure receiving portion 111 and the pressing block 22, so that the clamping and fixing of the product 200 are realized. Further, the product 200 can be released from the clamping by reversely unscrewing the pressing bolt 21, so that the product 200 can be taken out from the clamping area. The structure is simpler, the clamping and fixing are firm and reliable, and the installation and dismounting operation of the product 200 is more labor-saving and convenient.

[0023] Alternatively, in the embodiment, the first mounting convex portion is a first mounting positioning column 12 which is outwardly convex and formed on the mounting base 10, and the second mounting convex portion is a second mounting positioning column 13 which is outwardly convex and formed on the mounting base 10.

Thus, the first mounting positioning column 12 and the second mounting positioning column 13 are more convenient to be positioned and fixed on the chuck of the lathe, and the structure is more reasonable. More preferably, in the embodiment, the first planar positioning portion 121 is parallel to the axis of the first mounting positioning column 12, and the second planar positioning portion 131 is parallel to the axis of the second mounting positioning column 13, so that the structure and layout of the first planar positioning portion 121 and the second planar positioning portion 131 are more reasonable and convenient for production and processing.

[0025] Alternatively, in the embodiment, the second mounting positioning column 13 is perpendicular to the first mounting positioning column 12, so as to meet the switching processing of the product 200 in two mutually perpendicular axial directions, and the structure is more reasonable.

[0026] The working principle of the reversible clamping clamp 100 of the utility model will be described in detail in combination with the drawings.

[0027] First, the product 200 to be processed is placed in the clamping area between the limiting pressure receiving portion 111 and the pressing top block 22, and then the top pressing bolt 21 is rotated to move towards the limiting pressure receiving portion 111, so that the top pressing bolt 21 pushes the pressing top block 22 to move towards the limiting pressure receiving portion 111, until the product 200 is clamped and fixed between the limiting pressure receiving portion 111 and the pressing top block 22, thereby achieving clamping and fixing of the product 200 (as shown in the figure). Figure 4

[0028] Then, the first mounting protrusion is fixedly installed on the chuck of the lathe, and the product 200 can be processed along the axial direction of the first mounting protrusion.

Therefore, only the product 200 to be processed is placed in the clamping area, the product 200 is pressed by the pressing mechanism 20, so that the product 200 is clamped and fixed between the pressing mechanism 20 and the limiting pressure receiving portion 111, thereby clamping and fixing the product 200 in the accommodating groove 11 of the mounting base 10, and then the first mounting protrusion is fixedly installed on the chuck of the lathe, so that the product 200 can be processed along the axial direction of the first mounting protrusion. After processing is completed, the first mounting protrusion is disassembled from the chuck of the lathe, and the second mounting protrusion is fixedly installed on the chuck of the lathe, so that the product 200 can be processed along the axial direction of the second mounting protrusion until the product 200 is processed. Thus, the reversible clamping of the reversible clamping clamp 100 of the utility model is realized, so that only the first mounting protrusion and the second mounting protrusion need to be disassembled and assembled each time the direction is changed, and the product 200 does not need to be disassembled and clamped again, which greatly improves the disassembly and assembly speed, and the direction changing disassembly and assembly are fast, time-saving and labor-saving, greatly reducing the required labor cost, thereby greatly improving the production and processing efficiency. Moreover, the product 200 can be better protected from damage caused by repeated clamping, the appearance of the product 200 is less damaged, the product 200 can be better protected, and the yield of the product 200 is greatly improved, thereby greatly reducing the production and processing cost.
