Wherein, actuating mechanism connects cutting mechanism 2, and cutting mechanism 2 is used for carrying out the extrusion cutting to the material. The driving mechanism is used for driving the cutting mechanism 2 to move away from the cutting direction, namely, when the cutting mechanism 2 finishes one-time cutting, the driving mechanism drives the cutting mechanism 2 to move towards the direction away from the material, and preparation is made for next cutting. Two ends of the elastic mechanism 1 are respectively arranged on the fixed bracket 5 and the cutting mechanism 2; when the driving mechanism exerts no acting force on the cutting mechanism 2, the elastic mechanism 1 drives the cutting mechanism 2 to move towards the cutting direction through the elastic force.

In some possible embodiments, the driving mechanism comprises a driving cylinder 4 disposed on the fixed support 5, and the cutting mechanism 2 comprises a knife seat 21 and a cutting knife 22. Wherein, cutter 22 can dismantle and connect on blade holder 21, and cutter 22 can dismantle through the screw and connect on blade holder 21, and the later stage of being convenient for is changed or is maintained cutter 22.

The driving cylinder 4 is connected to the tool post 21 through a driving rod 6, and the driving rod 6 may be fixedly connected to the tool post 21 or screwed to the tool post 21. When the cutter 22 finishes one-time material cutting, the driving cylinder 4 drives the cutter 22 to move towards the direction far away from the cutting direction through the cutter holder 21, so as to prepare for next material cutting. The driving cylinder 4 can be only provided with one air inlet valve, and when the driving cylinder 4 drives the tool apron 21 to move, the air inlet valve is controlled to admit air; when the air inlet valve is controlled to deflate, the driving air cylinder 4 loses acting force on the cutter holder 21, and the cutter holder 21 moves towards the material under the action of the elastic mechanism 1 to cut the material.

When the material is ready to be cut, the driving cylinder 4 is deflated and no force is applied to the tool apron 21. Under the action of the elastic force of the power spring 15, a fixed acting force towards the cutting direction is applied to the cutter holder 21, so that the fixed acting force of the cutter 22 on the material is consistent each time. In the whole working process, the power spring 15 is always in a compressed state, the power spring 15 can be a spring with a large elastic coefficient, larger acting force can be applied to the material through the cutter 22 conveniently, and the material is cut off more easily. When the material cutting is finished, the driving cylinder 4 is driven to intake air, the tool apron 21 is driven to move towards the direction far away from the material through the driving rod 6, preparation is made for next cutting, and in the process, the power spring 15 is gradually compressed.

The plurality of adjusting screw groups are used for adjusting the height of the limiting plate 11 so as to adjust the fixing acting force of the power spring 15 on the cutter holder 21, and therefore the fixing acting force of the cutter 22 on the material is adjusted. Specifically, when adjusting limiting plate 11 and being closer to the material, the position of material is unchangeable, and power spring 15 orders about cutter 22 when cutting the material, and power spring 15's compressive capacity can be bigger, and cutter 22 is also bigger to the cutting effort of material, can be more stable cut off the material. The distance between the limiting plate 11 and the material can be adjusted according to the thickness degree of the material.
