[0042] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0043] In summary, with the aid of the above technical solution of the present invention, the guide rod is installed on one side of the threaded block 403, and the threaded block 403 is limited in rotation by the guide rod so that it can only be adjusted in height when it is transmitted on the threaded rod 402. The adjusting motor 401 drives the threaded rod 402 to adjust the threaded block 403. One side of the threaded block 403 is fixedly connected to the driving structure 5. The electromagnet 503 of the driving structure 5 is connected to a voltage control device through a cable reel, which can change the current direction of the electromagnet and the on-off of the current, so that the electromagnet 503 can produce The magnetic poles opposite to or the same as those of the magnetic block 502 are generated to generate a repulsive force or a magnetic attraction force. The repulsive force causes the magnetic block 502 to slide in the sliding cavity of the adjustment slot 501, driving the drive motor 504 to move. A shielding layer is provided between the drive motor 504 and the magnetic block 502 to prevent the magnetic block 502 from causing magnetic interference to the drive motor 504. The drive motor 504 moves so that its transmission pin 505 connects to the guide positioning slot 906. At the same time, it can continuously push the positioning block 901 to make its fitting block 902 disengage from the limit fitting slot 1002, and then drive The driving motor 504 precisely controls the rotation angle through servo control, so that the positioning block 901 rotates ninety degrees. Then the electromagnet 503 generates a magnetic pole opposite to the facing surface of the magnetic block 502 through the control circuit, generating a magnetic attraction, so that the magnetic block 502 drives the transmission pin 505 to reset. At the same time, since one end of the transmission spring 8 contacts the retaining ring 607 and the other end of the transmission spring 8 contacts the groove body of the installation groove 303, the transmission spring 8 is in a compressed state when the transmission rod 601 and the gear lever 701 are in a locked state, and the positioning block 901 is free from the restricted rotation of the limit fitting groove 1002. After ninety degrees, the lead-out engaging groove 1001 engages with the engaging block 902, and the engaging block 902 is released from the restriction. As the transmission pin 505 is reset and the elastic force of the transmission spring 8 is released, the engaging block 902 slides out from the lead-out engaging groove 1001, thereby driving the transmission rod 601 to move, so that its rack 603 drives the gear ring 702 of the fixed structure 7 to transmit, so that its blocking rod 701 rotates through the rotating support ear 703, so that its blocking rod 701 cannot fix the connecting cavity 11, and now it is convenient to directly disassemble the corresponding module unit.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
