In the utility model patent "A Safety Management Device for On-Site Construction of Electric Power Infrastructure Projects" with the application number "202120201075.1", the scheme controls the operation of the motor through an external switch, and the motor drives the fixed cylinder to rotate. The screw rod connected by internal thread meshing moves up and down along the vertical direction of the fixed cylinder. With the up and down movement of the screw rod, the height adjustment of the workbench is realized, which saves manpower and also ensures the safety of the operator. The personal safety of the operator is prevented from falling from high altitude, and it does not affect the work of the constructor. It is flexible and safe, but there are still some defects in this scheme:

1. This solution needs to use multiple motors through the height adjustment of the workbench, which increases the production cost of the device and the maintenance cost in the later stage;
