[0028] A limit block 9 is arranged on the inner wall of the mounting plate 1, and the outer wall of the limit block 9 is slidably connected to the inner wall of the mounting plate 1. A spring 1 is fixedly installed between one side of the limit block 9 and the inner wall of the mounting plate 1. A connecting plate 10 is arranged on one side of the limit block 9, and one end of the connecting plate 10 is connected to one side of the limit block 9, so that the limit block 9 can be quickly and conveniently connected to the connecting groove provided on one side of the mounting block 7, and thus can be fixed without a large number of fixing bolts, and can be used better;

[0029] A fixing plate 11 is disposed at one end of the connecting plate 10, one side of the fixing plate 11 is connected to one end of the connecting plate 10, a limiting rod 12 is disposed on the inner wall of the fixing plate 11, and the outer wall of the limiting rod 12 is slidably connected to the inner wall of the fixing plate 11;

When disassembly and separation are required, the operator pulls the limit rod 12 to slide inside the fixing plate 11, slides and squeezes the spring 2 through the limit rod 12, and pulls the limit rod 12 out of the limit hole. At this time, the fixing plate 1 is pulled. 1 moves to drive the connecting plate 10 to move, and the movement of the connecting plate 10 drives the limit block 9 to move. The movement of the limit block 9 can squeeze the spring 1, and the limit block 9 can be pulled out of the clamping groove, so that the limit fixation of the mounting block 7 can be cancelled. At this time, the mounting plate 2 is pulled to drive the mounting block 7 and the mounting rod 8 to move, so that the mounting block 7 and the mounting rod 8 are pulled out of the mounting groove 5 and the mounting hole 6, and the disassembly and separation are completed. When it is necessary to install it, the above steps can be repeated in reverse to install it for use. By installing the mounting rod 8 and opening the mounting hole 6, the connection strength between the mounting plate 1 and the mounting plate 2 can be increased, so that it can be better used, and the stability of the equipment during use is improved.
