The rotating threaded tube controls the movement of the internal moving components, thereby completing the disassembly and assembly of the control box. It is also very convenient to disassemble and assemble in a place with a relatively narrow space, reducing the complexity of the disassembly and assembly work and facilitating maintenance.

[0007] As a preferred implementation, a groove is formed on the lower surface of the connecting plate body, and the shell is inserted into the groove.

[0008] The grooves are provided to provide connection points for the main body components.

[0009] As a preferred implementation, a hole groove is opened inside the connecting plate body, and the limiting rod is inserted into the hole groove.

[0010] A connection point is provided for the limit rod by setting a hole slot.

[0011] As a preferred implementation, the limiting rod is inserted into the through hole, and the cross-sections of the hole slot, the through hole and the limiting rod are all square.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model provides a limit rod, a threaded block, a knob, a main shaft, a worm, a threaded tube, a worm wheel and a bearing. The worm is controlled to rotate by rotating the knob. The worm drives the threaded tube to rotate through the worm wheel. The rotating threaded tube controls the movement of the internal moving components, thereby completing the disassembly and assembly of the control box. The disassembly and assembly is also convenient in a place with a relatively narrow space, reducing the complexity of the disassembly and assembly work and facilitating maintenance.

[0019] The utility model is provided with a hole groove, a through hole, a limiting rod, a threaded block and a limiting ring, and the cross sections of the hole groove, the through hole and the limiting rod are designed to be square, so as to avoid the moving component from rotating with the rotation of the threaded tube, thereby realizing the linear motion of the moving component.
