the magnetic layers, the rightmost end of the clamping rod 27 is tightly fixed in the rod groove, so that the elevator door 1 in the state between opening and re-closing is locked, in the process, the base plate 285 drives the rotating rod 286 to move along with the L-shaped plate 24, the bottom plate 281 drives the second gear teeth 282 to move rightwards synchronously with the U-shaped plate 25, when the rotating rod 286 meets the bottom plate 281, the rotating rod 286 rotates under the matching with the bottom plate 281 and pushes the bottom plate 281 forwards, the bottom plate 281 drives the second gear teeth 282 to move synchronously, the first gear teeth 280 drives the clamping rod 27 to move synchronously under the matching with the second gear teeth 282, at the moment, the locking spring 29 is driven by the clamping rod 27 to move synchronously in a twisting manner and is pressed into the circular through hole in a rotating manner under the action of a block 28, on the basis of the elasticity of the locking spring 29, the locking spring 29 is clamped in the circular through hole, when the bottom plate 281 is separated from the rotating rod 286, the bottom plate 281 drives the second gear teeth 282 to reset under the action of the resetting spring 283, the matching among the bottom plate 281, the first gear teeth 280, the second gear teeth 282 and the rotating rod 286 can play a role in improving the clamping degree of the clamping plate on the basis of the opening and closing movement of the elevator door 1, meanwhile, when the L-shaped plate 24 moves leftwards along with the elevator door 1 connected with the L-shaped plate 24, the L-shaped plate drives the push rod 240 to move synchronously, the push rod 240 pushes the rotating plate 242 synchronously, the rotating plate 242 rotates upwards synchronously along the pin shaft, the rotating plate 242 drives the clamping plate 243 to rotate synchronously, when the rotating plate 242 rotates to be in a vertical state, the left end of the elevator door 1 connected with the L-shaped plate 24 is just clamped between the clamping plate 243, the push rod 240, the rotating plate 242 and the L-shaped rod are matched to play a certain role in fixing the elevator door 1, the disc 23 drives the shaft rod 22 to rotate synchronously along with the movement of the elevator door 1 through the meshing movement between the third gear teeth 230 and the fourth gear teeth 231, the shaft rod 22 drives the clamping plate 220 to rotate synchronously, the clamping block 220 drives the clamping block 222 to rotate synchronously, when the clamping rod 27 is contacted with and clamped in the rod groove, the clamping plate 220 drives the clamping block 222 to rotate rightwards along the block groove, at the moment, the clamping block 222 is positioned in the installation groove and presses the spring rod 221 synchronously, when the fixture 222 is in butt joint with the clamping groove, the fixture 222 is clamped in the clamping groove under the action of resilience of the spring rod 221, the clamping plate 220 and the car plate 20 are relatively fixed, and the clamping rod 27 is clamped in the rod groove at the moment, the whole relative static degree of the clamping rod 27 after being fixed can be improved through the cooperation among the clamping plate 220, the fixture 222, the spring rod 221 and the car plate 20, the landing door 202 performs opening and closing motions independently on the elevator door 1 at the same time, the landing door 202 drives the rotating rod 286 to synchronously move in the opening process, the rotary disc 204 synchronously rotates around the fixed shaft 203 under the driving of the rotating rod 286, the rotary disc 204 drives the supporting rod 207 to synchronously rotate, the supporting rod 207 drives the pushing rod 208 to synchronously move, the moving block 209 synchronously performs horizontal linear motion along the rear inner side wall of the rectangular groove under the driving of the pushing rod 208, when the clamping rod 27 is in contact with the rod groove, the inner bottom wall of the moving groove is in contact with the moving block 209, in the process that the position clamping rod 27 continues to move and is clamped in the rod groove, the moving groove rotates along with the rotary disc 204, meanwhile, the moving block 209 is gradually clamped in the moving groove, at the moment, the landing door 202 is in a fully opened state and stops opening movement, and the rotary rod 286, the rotary disc 204, the support rod 207, the push rod 208 and the moving block 209 are matched to play a synchronous locking role in the landing door 202 in the opened state.
