[0024] Furthermore, a circuit board 5 is fixed inside the left fixing component 4 and the right fixing component 4, and the fixing component 4 is used to fix the circuit board 5.

The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] When the spacing of the circuit boards 5 needs to be adjusted, the two control blocks 3 are rotated at the same time, so that the two adjustment blocks 2 can be rotated, and the adjustment blocks 2 are threadedly connected to the adjustment rods 1, so that the adjustment blocks 2 can move due to the extrusion of the threads, thereby adjusting the spacing of the circuit boards 5. When the circuit boards 5 need to be disassembled, the fixing rods 402 can be pulled to make the fixing rods 402 overcome the prestress of the fixing springs 404 and move upward, so that the fixing rods 402 and the circuit boards 5 lose their plug-in connection. At this time, the circuit boards 5 can be pulled to move toward the front, so that the circuit boards 5 move to the outside of the fixing slots 405. , the disassembly of the circuit board 5 is completed, and when the circuit board 5 is installed, the fixing rod 402 is pulled to slide the circuit board 5 into the fixing groove 405. The fixing groove 405 is set so that the positioning block 401 limits the movement of the circuit board 5 in the up and down directions. When the fixing rod 402 is released, the prestress of the fixing spring 404 will push the fixing rod 402 to reset and plug into the circuit board 5, thereby limiting the horizontal movement of the circuit board 5, and then the circuit board 5 can be effectively fixed. The overall structure is simple, and no professional tools are required to disassemble the circuit board 5, which can effectively improve the overall practicality.
