The first rotating plate 74 and the second rotating plate 75 are provided with a rotating pair 77 which is rotatably connected along the width direction, and the rotating pair 77 is fixed on the fixed leg 1 and positioned at one side close to the gear teeth 3 of the moving leg 2; one end of the first rotating plate 74 is rotatably connected with one end of the second rotating plate 75 through a lock catch 79, the other end of the first rotating plate 74 is rotatably connected with the connecting rod 722, one end of the second rotating plate 75, which is far away from the first rotating plate 74, is rotatably connected with the locking rod 76, the locking rod 76 faces the end face of the adjusting gear 4, and the end face of the adjusting gear 4 is provided with a plurality of locking holes 41 matched with the locking rod 76; when the handle grip 6 is pressed, the lock lever 76 can be pulled out from the lock hole 41; when the handle grip 6 is pulled up, the lock lever 76 can be inserted into the different lock holes 41, so that the adjustment gear 4 is locked.
In this embodiment, the downward pressure of the handle grip 6 pushes the hexagonal socket 5 downward until the skirt 52 is caught under the limit catch in the hexagonal hole 43 of the adjustment gear 4, and on the other hand, the downward pressure of the intermediate rod 63 of the handle grip 6 pushes the first push rod 71 downward. Due to the pressing force of the handle, the hexagonal base 5 moves downward, further pushing the second push rod 72 to move axially for a certain distance. The first rotating plate 74 and the second rotating plate 75 are both fixed on the fixed leg 1 through the rotating pair 77, so that the first rotating plate 74 and the second rotating plate 75 can only rotate around the corresponding rotating pair 77, the second push rod 72 pushes one end of the first rotating plate 74, the other end of the first rotating plate 74 rotates along with the first rotating plate, the second rotating plate 75 is driven to rotate correspondingly, and finally, the rotating motion of the tail end of the locking rod 76 is driven, so that the locking rod 76 is separated from the locking hole 41, and the unlocking purpose is achieved; when the lock is performed, the second rotating plate 75 presses the lock lever 76 downward toward the adjustment gear 4, and the lock lever 76 is inserted into the lock hole 41, thereby locking the adjustment gear 4.
Still further, in implementation, because the locking rod 76 is rotatably connected with the second rotating plate 75, in order to ensure that the locking rod 76 can accurately enter the corresponding locking hole 41, the fixed leg 1 is further provided with the guide rod 78, the guide rod 78 is parallel to the rotating pair 77, the end of the guide rod 78 is provided with the guide ring 781, and the guide ring 781 is sleeved on the locking rod 76, so that the locking rod 76 accurately corresponds to the locking hole 41.
