The positioning rod 7 is movably arranged on the mounting frame 2, the tail end of the positioning rod 7 corresponds to the handle 31 of the pressing clamp 3, and the handle 31 of the pressing clamp 3 pushes the positioning rod 7 to move on the mounting frame 2 to form a second clamping position 20.
Specifically, the positioning frame 6 comprises a driving plate 62 connected with the driving rod 32 of the pressing pliers 3, guide rods 61 positioned at two ends of the driving plate 62 and matched with the mounting frame 2 in a guiding manner, and positioning pins 63 positioned at the ends of the driving plate 62; the support plate 22 is provided with a guide hole through which the guide rod 61 and the positioning rod 7 move. The mounting frame 2 is provided with a positioning tube 23 which corresponds to the positioning pin 63 and forms a first clamping position. When clamping, one end of the positioning pin 63, which faces away from the driving plate 62, can penetrate through the through hole in the connecting plate 5 and enter the positioning tube 23, that is, the outer step surface of the positioning pin 63 and the end surface of the positioning tube respectively abut against two sides of the connecting plate 5.
The locating lever 7 is sleeved with a spring 8 which drives the locating lever 7 to reset, one end of the spring leans against the supporting plate 22, and the other end of the spring leans against an outer step on the outer side wall of the locating lever.
