When the control chip needs to be replaced, a force is applied to the positioning plate 5413 to pull the housing 5411 out of the control box 50, the old control chip is pulled out, and a new control chip is inserted into the clamping space 5415 of the housing 5411 and clamped in the clamping groove of the push plate. The inserting assembly 54 is movably inserted into the box body 51, so that the control chip can be conveniently inserted and installed. Thereafter, the housing 5411 is pushed into the insertion hole of the box body 51, so that the positioning plate 5413 is positioned in the receiving ring groove. In this process, the housing 5411 pushes the arc-shaped elastic plate 521 to deform and finally make the baffle 522 on the arc-shaped elastic plate 521 apply force on the housing 5411 and close the opening of the housing 5411, the insertion plug 523 is inserted into the clamping space 5415 and abuts against the top of the rotating clamping plate 543, so that the rotating clamping plate 543 rotates and clamps the control chip until the rotating clamping plate 543 is arranged on the baffle bump. The two elastic electrical terminals 511 in the box body 51 are compressed by the side walls of the housing 5411 and contract until the two elastic electrical terminals 511 are aligned with the two electrical connection holes 5416 and inserted into the two electrical connection holes 5416, so that the electrical connection between the circuit structure in the box body 51 and the control chip is realized. In an embodiment, the tops of the two elastic electrical terminals 511 are both arc-shaped, so that when the housing 5411 is pulled out, the two elastic electrical terminals 511 can be conveniently pulled out of the housing 5411.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
