And the blanking pipe has a plurality of, and the external diameter of blanking pipe is the same and the internal diameter is different. After changing the unloading pipe, the internal diameter of unloading pipe changes, can place the different rubber tube of pipe diameter for it is wider to cut a tub structure application range.

As shown in fig. 1, the rack 1 includes a lower squeeze rivet body 11, a placing plate 12, a limiting post 13 and a second limiting plate 14, wherein the upper surface of the lower squeeze rivet body 11 is horizontal for placing a bound object, and the placing plate 12 is fixedly connected to the lower surface of the lower squeeze rivet body 11. The number of the limiting columns 13 is two, the limiting columns 13 extend upwards from the placing plate 12, and the limiting columns 13 are fixedly connected with the placing plate 12 and the lower squeeze riveting body 11 respectively. The part of the limiting column 13 above the lower squeeze rivet body 11 is connected with the lower squeeze rivet body 2 in a sliding way. The second limiting plate 14 is fixedly connected to the upper end of the limiting column 13, and the upper press riveting body 2 is arranged below the second limiting plate 14, so that the range in which the upper press riveting body 2 can move up and down is limited.

Specifically, as shown in fig. 1, at the joint of the pipe cutting structure 3 and the lower squeeze rivet body 2, the lower squeeze rivet body 2 is recessed inwards to form an accommodating cavity, which is convenient for installing the pipe cutting structure 3. At this time, the distance between the cutter 31 and the lower squeeze rivet body 11 is larger than the thickness of the bound object, so that the length of the rubber hose cut by the cutter 31 is slightly longer than the thickness of the bound object, and the binding effect is better.

As shown in fig. 3, the first driving structure 6 includes a first motor 61, a first gear 62, a first transmission member 63, and a third limiting block 64.

Further, the first motor 61 is fixedly connected to the placing plate 12, the first gear 62 is rotatably connected to the upper surface of the placing plate 12, the first gear 62 and the first motor 61 are rotatably connected, and two end surfaces of the first gear 61 penetrate through a through hole, and a thread is disposed in the through hole.

Under the limiting action of the limiting column 13, the second transmission piece 71 can only drive the upper riveting body 2 to move up and down.

It can be understood that, in the present embodiment, the limiting column 13 penetrates the third limiting block 64. At this time, the first stopper 4 may not penetrate through the lower squeeze rivet body 11 or the through hole corresponding to the first stopper 4 on the lower squeeze rivet body 11 may be larger than the cross section of the first stopper 4, that is, the lower squeeze rivet body 11 may not limit the first stopper 4. Under the limiting action of the limiting column 13, the third limiting block 64 can only move up and down.

When the second motor 71 rotates forward, the second transmission member 73 moves downward, and when the second motor 71 rotates backward, the second transmission member 73 moves upward.

When the second motor 51 rotates forward to press the bound object, the upper rivet press body 2 moves downward to press the bound object. After the tube cutting is completed, the second motor is reversed, at which time the upper squeeze rivet 2 moves upward to release the staples.

A binding machine comprises a drilling device and the pipe cutting device. The drilling device comprises a drill 8, and the drill 8 is sleeved on the upper end of the first transmission part 63.

It can be understood that after the second transmission mechanism 73 presses the bookbinding products, the first driving mechanism 6 drives the trigger pipe cutting mechanism of the upward movement of the first stopper 4 to cut the pipe, and the drill 8 arranged at the upper end of the first transmission member 63 penetrates through the lower squeeze rivet body 11 to drill the bookbinding products.

It will be appreciated that a through hole larger than the diameter of the drill 8 is provided in the lower squeeze rivet body 11 for the drill 8 to pass through.
