[0037] The working principle of the utility model is as follows: when it is necessary to fix the instrument housing, first install the installation box 2 in the required installation area through the installation plate and the installation hole, then sleeve the installation plate on the back of the instrument housing on the surface of the right-angle clamping plate 13 on the front of the installation box 2, then turn the hand wheel, the hand wheel drives the rotating rod 16 to rotate, the rotating rod 16 drives the bidirectional lead screw 4 to rotate, the bidirectional lead screw 4 drives the cam 6 and the sliding sleeve 5 to move, the cam 6 rotates to squeeze the top plate 7, the top plate 7 is squeezed and moved, the top plate 7 drives the roller 8 to move, the roller 8 squeezes the inclined block 12, the inclined block 12 moves to both sides of the installation box 2, the inclined block 12 drives the right-angle clamping plate 13 to move, the right-angle clamping plate 13 moves, so that one side of the right-angle clamping plate 13 is fixed to the card groove 15 of the inner cavity of the installation block 3, thereby fixing the main body 1;

[0038] At the same time, when the two-way screw 4 rotates, it will drive the two sliding sleeves 5 on the surface to move relative to each other, and the sliding sleeve 5 drives the movable arc plate 10 to move, and the gap between the movable arc plate 10 and the fixed arc plate 11 is reduced. At this time, the limit pin 17 can be screwed into the handwheel to limit it, and the external wiring placed in the inner cavity of the wiring port 9 is clamped and combed to prevent the line from being chaotic, which makes the instrument housing inconvenient to disassemble during disassembly, maintenance and repair. In this way, the fixing work of the instrument housing can be completed, and when the movable arc plate 10 needs to move a large distance to clamp and comb the line, when the gap between the movable arc plate 10 and the fixed arc plate 11 is sufficient, but the cam 6 does not support the top plate 7, the two-way screw 4 can be turned half a circle more or less to make the cam 6 push the column cam.
