A rectangular clamping block 11 is fixedly connected to the output end of the electric telescopic rod 10. The clamping block 11 is pushed by the electric telescopic rod 10 to clamp the left and right ends of the electrical switch cabinet. By rotating the screw rod 3, the first slider 4 can be driven to move along the surface of the screw rod 3, and then the first slider 4 and the second slider 6 drive the support plate 7 to move up and down, thereby driving the electrical switch cabinet to rise and fall. By driving the turntable 8 to rotate by the second motor 18, the electrical switch cabinet can be driven to rotate, thereby adjusting the angle of the electrical control cabinet for easy assembly.

[0023] Reference Figure 1 and Figure 3 As shown, a first motor 9 for driving the turntable 8 to rotate is fixedly installed on the outer side of the support plate 7, a third motor 20 for driving the screw rod 3 to rotate is fixedly installed on the upper end of the rear bracket 2, and a placement table 19 is fixedly connected to the center of the upper end of the workbench 1.

[0024] Reference Figure 3 and Figure 4As shown, rectangular slide grooves 12 are provided at the upper and lower ends of the clamping block 11, and a bidirectional threaded rod 13 is rotatably connected inside the slide groove 12. Both ends of the bidirectional threaded rod 13 are threadedly connected to sliding plates 21, and guide rods 14 are fixedly connected at the four corners of the outer side of the sliding plate 21.

[0025] Working principle: When the device is in use, the electrical switch cabinet is first placed on the upper end of the placement table 19, and then the clamping block 11 is pushed by the electric telescopic rod 10 to approach the left and right sides of the electrical control cabinet for clamping. When the clamping block 11 is in contact with the left and right sides of the electrical control cabinet, the second motor 18 drives the second bevel gear 17 to rotate. Driven by the second bevel gear 17, the first bevel gear 16 will drive the bidirectional threaded rod 13 to rotate, so that the two sliding plates 21 drive the two side clamping plates 15 to approach each other to clamp the front and rear sides of the electrical switch cabinet. When the side clamping plates 15 are in contact with the front and rear ends of the electrical switch cabinet, they can be assembled.
