Referring to fig. 7, in the present embodiment, the horizontal sliding groove 601 is disposed in the fixed casing 301 along the horizontal direction, the first sliding groove 6011 and the second sliding groove 6012 are both disposed along the horizontal direction, the locking rod 602 is disposed in the first sliding groove 6011 in a horizontal sliding manner, the locking rod 602 can be completely received in the first sliding groove 6011, the slot 606 is disposed on the side wall of the movable plate 303, one end of the locking rod 602 away from the horizontal sliding groove 601 is adapted to the slot 606, and when the movable plate 303 slides downward to the lower limit position, the slot 606 is opposite to the locking rod 602; the adjusting rod 603 is horizontally slidably arranged in the second sliding groove 6012, the connecting rod 604 is horizontally slidably arranged in the horizontal sliding groove 601, one end of the connecting rod 604 is connected with one end of the locking rod 602 located in the horizontal sliding groove 601, the other end of the connecting rod 604 is connected with one end of the adjusting rod 603 located in the horizontal sliding groove 601, and the connecting rod 604 can drive the locking rod 602 and the adjusting rod 603 to slide in respective sliding grooves while sliding in the horizontal sliding groove 601; the second elastic member 605 is disposed between the connecting rod 604 and the side wall of the horizontal sliding slot 601, and under the action of no external force, the second elastic member 605 will push the connecting rod 604 against the side wall of the horizontal sliding slot 601 near the vertical sliding slot 501, and at this time, the adjusting rod 603 and the locking rod 602 are both partially located in the vertical sliding slot 501.
In addition to the case of the present embodiment, the horizontal chute 601, the first chute 6011, and the second chute 6012 are designed to be inclined to achieve the above-described effects.
The principle of the locking rod 602 locking the movable plate 303 is as follows: during the downward sliding of the movable plate 303, the movable plate 303 contacts the locking rod 602 and pushes the locking rod 602 into the first sliding groove 6011, and then the end of the locking rod 602 abuts against the sidewall of the movable plate 303 until the movable plate 303 slides to the lower limit position, at which time the locking rod 602 is opposite to the locking groove 606, and the second elastic member 605 pushes the locking rod 602 into the locking groove 606, so as to lock the movable plate 303.
In this embodiment, since the movable plate 303 slides downward by the elastic force of the first elastic member 504 and the gravity of the movable plate, when the vertical width of the locking rod 602 is equal to the vertical width of the locking slot 606, the movable plate 303 may bounce upward at the moment when it just reaches the lower limit position, so that the locking rod 602 cannot be locked in the locking slot 606, and the formation of the bump is affected, which is preferable: the vertical width of the locking groove 606 is greater than the vertical width of the locking rod 602, in this case, when the movable plate 303 slides downward to be close to the lower limit position, the locking rod 602 is already locked in the locking groove 606, when the movable plate 303 is reset upward by a small distance under the action of the first elastic member 504, the locking rod 602 abuts against the lower surface of the locking groove 606 to lock the movable plate 303, and meanwhile, the movable plate 303 has a tendency to slide upward when locked.
In this embodiment, since the movable plate 303 needs to push the locking rod 602 into the first sliding groove 6011 during the downward sliding process, which requires that a horizontal pushing force is generated when the movable plate 303 contacts the locking rod 602, a side wall of the movable plate 303, which is located in the vertical sliding groove 501 and is first contacted with the locking rod 602, is designed to be an inclined slope or an arc surface, so that when the end of the locking rod 602 contacts the movable plate 303, due to the existence of the inclined surface, a horizontal component force is generated between the movable plate 303 and the locking rod 602, and the movable plate 303 pushes the locking rod 602 into the first sliding groove 6011 through the horizontal component force.
The principle of the unlocking device 7 is as follows: during the downward sliding process of the movable plate 303, the unlocking device 7 is not in use, when the movable plate 303 needs to slide upward, the unlocking device 7 pushes the adjusting rod 603 toward the direction close to the horizontal sliding groove 601, because the connecting rod 604 connects the adjusting rod 603 with the locking rod 602, the adjusting rod 603 drives the connecting rod 604 to slide in the horizontal sliding groove 601 during the sliding process of the second sliding groove 6012, the connecting rod 604 drives the locking rod 602 to exit from the clamping groove 606 during the sliding process, and at this time, the movable plate 303 slides upward under the action of the first elastic member 504 and the first electromagnet 502.
