When the transmission rod 251 moves up, the push-pull rod 251 of the right side beltway 120 and the right lower side beltway 110 are synchronously driven to move. The push-pull rod 251 of the right side beltway 120 is connected with the push-pull rod of the upper side beltway 130 through the connecting rod 252, so as to drive the push-pull rod connection of the upper side beltway 130 to move left. The push-pull rod of the upper side beltway 130 is connected with the push-pull rod of the left side beltway 140 through the connecting rod, so that the push-pull rod connection of the upper side beltway 130 drives the push-pull rod of the left side beltway 140 to move down while moving left. The lower end of the push-pull rod of the left side beltway 140 is also connected with the push-pull rod of the left lower side beltway 150 through the connecting rod, so that the push-pull rod of the left side beltway 140 drives the push-pull rod of the left lower side beltway 150 to move right while moving down. Each beltway is provided with a rotating rod, a first swing rod and a second swing rod. The opening and closing block on the push-pull rod pushes the second swing rod, so that the rotating rod rotates, thereby pushing the two side cover plates 30 apart.

[0055] The connecting end of the first swing rod, the second swing rod and the push-pull rod with the cam is provided with a rolling bearing, so as to reduce the wear of the parts.

[0056] The above only describes the preferred embodiments of the present application, and is not used to limit the present application.
