The working principle of the invention is as follows:
when initially in use, the locking mechanism is in a locked initial state, i.e., the locking pin 32 remains extended. When locking is required, the movable chassis 2 is pushed until the locking pin 32 moves into the pin hole of the locking guide block 43 to lock. When unlocking, the handle 41 is turned, the main gear 21 rotates to drive the left and right gear shafts to rotate, and simultaneously the left gear connecting rod 18 and the right gear connecting rod 24 are driven to rotate in opposite directions.
