step S3, when the limiting punch 321 abuts against the limiting switch 620, the insert board 200 is just inserted into the jack 711 on the back board 710, and the first electromagnet 410 and the second electromagnet 510 are electrically connected with the limiting switch 620, so that the second electromagnet 510 pushes out the second iron core 520, and the clamping slot 230 is just under the second iron core 520, so that the second iron core 520 can be successfully clamped into the clamping slot 230, and thus the clamping piece 500 can limit the insert board 200 to move relative to the mounting seat 100, and then the second electromagnet 510 transmits a signal to the first electromagnet 410, so that the driving piece 400 is reset after power failure;
step S4, after the maintenance platform is completed, a maintenance personnel turns off a switch of the maintenance platform to release the maintenance platform state, at this time, the second electromagnet 510 is powered off, and the second iron core 520 is retracted back into the second electromagnet 510, i.e. the clamping piece 500 does not limit the movement of the plugboard 200 relative to the mounting seat 100;
in step S5, the insert 200 is only moved out of the jack 711 of the back plate 710 under the action of the spring 220, and at the same time, the insert 200 drives the link assembly 300 to return, the first link 310 drives the rotating rod 110 to rotate in opposite directions with the driving beating plate 111, and when the baffle 210 on the insert 200 abuts against the first folding plate 611, the insert 200 returns to the initial state, the elevator returns to the normal maintenance state, and the maintenance personnel can control the elevator to move in the elevator shaft 700 through the moving button in the normal maintenance state at the top of the elevator car.
Through the use method of the overhaul platform, the automatic locking and automatic unlocking functions of the overhaul platform are realized, so that the overhaul platform is convenient for people to operate, and secondly, the overhaul personnel can safely operate on the overhaul platform.

2. The maintenance platform of an automatic elevator car without machine room according to claim 1, wherein a baffle is arranged on the plugboard, the baffle is located between the first folding plate and the second folding plate, a spring is sleeved on the plugboard, one end of the spring abuts against the baffle, and the other end of the spring abuts against the second folding plate.
3. The overhauling platform for the automatic elevator car without machine room according to claim 1, wherein the clamping piece comprises a second electromagnet, a second iron core is movably arranged on the second electromagnet, a clamping groove is formed in the inserting plate, the bracket is provided with a bolt in a penetrating mode, and a clamping hole corresponding to the bolt is formed in the inserting plate.
4. A method of use of an access platform for an automatic machine-room-less elevator car, applied to an access platform for an automatic machine-room-less elevator car according to any one of claims 1 to 3, characterized in that the method of use comprises:
step S1, when an elevator is in a normal maintenance state, a maintenance person starts a switch of a maintenance platform, starts a function of the maintenance platform state, the elevator keeps moving, when an inductor senses an induction head on a backboard, the elevator stops moving, and meanwhile, a first electromagnet pushes out a first iron core;
s2, the driving piece pushes the connecting rod assembly to act, and the connecting rod assembly drives the plugboard to move towards the back plate;
step S3, when the limiting beating plate abuts against the limiting switch, the inserting plate is inserted into the inserting hole on the back plate, the clamping piece limits the inserting plate to move continuously, and then the driving piece is powered off and reset;
step S4, after the maintenance platform works, a maintenance personnel closes a switch of the maintenance platform to release the state of the maintenance platform, and the clamping piece resets after power failure, namely, the clamping piece does not limit the plugboard to move relative to the mounting seat any more;
and S5, the plugboard is moved out of the jack of the backboard under the action of the elastic force of the spring, the elevator is restored to a normal maintenance state, and the elevator can be controlled to move in the elevator shaft through a moving button in the normal maintenance state at the top of the elevator car.
