Detailed Description

The present utility model is described in detail below by way of examples only for further explanation of the present utility model and is not to be construed as limiting the scope of the present utility model.

As shown in fig. 1 and 2, this embodiment discloses a multi-station table-type binding machine 2, which comprises a mounting rack 1, more than two binding machines 2 are arranged on the mounting rack 1, a seat body 3 is respectively arranged on two sides of the mounting rack 1, a rotating rod 4 is connected between the seat bodies 3, the seat body 3 capable of elastically compressing is in the prior art, namely, the seat body 3 comprises an outer frame, a hinge block which moves up and down is arranged in the outer frame, one end of the rotating rod 4 is hinged on the hinge block, a compression spring is arranged between the hinge block and the upper end face of the outer frame, a swing arm 5 is arranged between the binding machines 2, the rotating rod 4 passes through the front part of the swing arm 5, the tail part of the swing arm 5 is in transmission connection with a connecting rod 6, and further comprises a transmission gear 70 which is in transmission connection with a motor 7, namely, an output shaft of the motor 7 is configured with an output gear which is in transmission with the transmission gear 70, so as to realize transmission between the motor 7 and the transmission gear 70, the eccentric position of the connecting rod 6 and the transmission gear 70 is movably connected, a pressing shaft 8 is also inserted in the swing arm 5, the transmission gear 70 drives the swing arm 5 to swing and drives the upper end face 8 to swing down to press the pressing shaft 8 to press the upper end face of the binding machine 2, the upper end face of the swing arm 5 to the upper end face of the swing arm 5 to the pressing the upper end face of the swing arm 5, and the upper end of the swing arm 5 is connected with the upper end of the swing arm 6 and the upper end of the swing arm 9 through a shifting fork 5, namely a moving fork 20 is in the movable connection with the swing fork 20, and the upper end of the swing fork 20 is in the swing groove and the swing groove is connected to the upper end of the swing seat 20, and the swing seat is connected to the upper end of the swing seat and the swing seat is 20, and the upper end of the lower, and the lower is 20 is connected to the lower, and the lower and the 20 is.
