The implementation principle of the push type car fuel tank cap executor of the embodiment of the application is as follows:

when spring 31 elasticity is good, in the time of need closing the oil tank cap, at first press the oil tank cap, the oil tank cap will exert oneself and transmit for fore-set 2, fore-set 2 atress descends, spring 31 will be compressed, because the setting of stopper, fore-set 2 will rotate and descend, when fore-set 2 descends, spacing knot 322 is located the second spacing groove 3212 of spacing piece 321, and be located the department of bending of "V" shape of second spacing groove 3212, the stay 41 at fore-set 2 will with the oil tank cap between lock. When the oil tank cover needs to be opened, the oil tank cover is firstly pressed, force on the mailbox cover is transmitted to the top post 2, the force of the top post 2 is reduced, the limit buckle 322 enters the third limit groove 3213 of the limit sheet 321, then the resilience force of the spring 31 resets the limit buckle 322, the top post 2 can be popped out from the inside of the shell 1, and the oil tank cover can be opened.

When the spring 31 fails, the user needs to open the fuel lid, remove the top pillar 2 from the inside of the housing 1, and replace the spring 31. That is, the user starts the micro motor in the cab and energizes the first and

second electromagnets

5131 and 5132. The output shaft of the micro motor rotates to drive the chain wheel 514 and the first bevel gear 522 to rotate, the chain wheel 514 rotates to drive the toothed chain 512 to move, and the first electromagnet 5131 and the second electromagnet 5132 attract magnets. When the tooth-shaped chain 512 moves, the limiting sheet 321 is driven to move, and when the limiting sheet 321 moves up and down, the top column 2 can be driven to move up and down, so that the upright column can be extended out of the shell 1. Simultaneously, break away from the connection gradually between stopper and the fore-set 2, namely, at the in-process that the fore-set 2 rose, the stopper will with the fore-set 2 between sliding connection, when the fore-set 2 rose to the peak, the stopper will with the fore-set 2 between the disconnection, can be convenient for the lift between fore-set 2 and the casing 1 to the change of spring 31 of can being convenient for. When the spring 31 is replaced, the top column 2 is located at the highest point, and then the spring 31 is installed on the lower shell 12 and the top column 2, so that the operation is more convenient.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
