The symmetrically arranged supporting plates are slidably connected in the symmetrically arranged sliding grooves, and a cutting knife and an iron are respectively installed on the lower end faces of the symmetrically arranged cross plates. In the utility model, by arranging the cross plates, the slidably connected supporting plates, the cutting knife and the iron, the interlining can be ironed before cutting to ensure that the interlining is flat before cutting, so as to facilitate cutting, and after ironing, it is convenient for packaging.

[0003] When cutting spun interlining in the prior art, due to the fixed length of the scissors, when the length of the interlining is long, people need to lie on the table to ensure that the original cut can be continued for cutting. Therefore, this article aims to propose a cutting device for spun interlining, which increases the length of the scissors and improves the convenience during the cutting process. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when cutting spun interlining in the prior art, due to the fixed length of the scissors, when the length of the interlining is long, people need to lie on the table to ensure that the original cut can be continued for cutting. To improve its deficiencies, the utility model provides a cutting device for spun interlining.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A cutting device for spun interlining includes a hollow circular tube. One end of the hollow circular tube is fixedly connected with a handle, and a control rod is hinged on the handle. The upper end of the control rod is connected with a cross bar, and the cross bar penetrates through the hollow circular tube. The other end of the hollow circular tube is fixedly connected with a fixed blade, and a sliding groove is formed on the surface of the fixed blade. The free end of the cross bar is slidably connected in the sliding groove through a pin shaft. A cutting blade is hinged at the bottom of the fixed blade, and the upper end of the cutting blade is connected with the pin shaft in the sliding groove. A torsion spring is arranged at the hinge joint of the fixed blade and the cutting blade.

[0007] As a preferred solution, a connecting plate is arranged at the root of the fixed blade. The connecting plate is arranged inside the hollow circular tube, and the connecting plate and the hollow circular tube are fixed through a locking bolt.

[0008] As a preferred solution, the chute is arranged in an arc shape.

[0009] As a preferred solution, one end of the torsion spring is connected to the fixed blade, and the other end of the torsion spring is connected to the cutting blade.

[0010] As a preferred solution, a U-shaped connecting ring is hinged on the handle, and the control rod is fixedly connected to the connecting ring and moves integrally.

[0011] Compared with the prior art, the beneficial effect of the present utility model is that due to the coordinated setting of the cross bar, the cutting blade and the control rod, an operator can perform the cutting work of the lining cloth with a longer length through this device, avoiding the inconvenience caused by too long cutting length, thereby making the flatness of the cut poor. This device is applicable to industrial production and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is a structural schematic diagram of the present utility model.

[0013] Figure 2 is a structural schematic diagram of the fixed blade and the cutting blade in the present utility model.

[0014] In the figure: 1 hollow round tube, 2 handle, 3 control rod, 4 cross bar, 5 fixed blade, 6 chute, 7 cutting blade, 8 torsion spring, 9 connecting plate, 10 locking bolt, 11 connecting ring. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions of the present application will be further described and illustrated below in conjunction with the drawings and embodiments.

[0016] As Figure 1-2 shown, it is a cutting device for spun lining cloth, including a hollow round tube 1. One end of the hollow round tube 1 is fixedly connected with a handle 2. A control rod 3 is hinged on the handle 2. The upper end of the control rod 3 is connected with a cross bar 4. The cross bar 4 penetrates through the hollow round tube 1. The other end of the hollow round tube 1 is fixedly connected with a fixed blade 5. A chute 6 is arranged on the surface of the fixed blade 5. The free end of the cross bar 4 is slidably connected in the chute 6 through a pin shaft. A cutting blade 7 is hinged at the bottom of the fixed blade 5. The upper end of the cutting blade 7 is connected with the pin shaft in the chute 6. A torsion spring 8 is arranged at the hinged part of the fixed blade 5 and the cutting blade 7. A connecting plate 9 is arranged at the root of the fixed blade 5. The connecting plate 9 is arranged inside the hollow round tube 1. The connecting plate 9 and the hollow round tube 1 are fixed through a locking bolt 10. The chute 6 is arranged in an arc shape. One end of the torsion spring 8 is connected with the fixed blade 5, and the other end of the torsion spring 8 is connected with the cutting blade 7. A U-shaped connecting ring 11 is hinged on the handle 2. The control rod 3 is fixedly connected with the connecting ring 11 and moves integrally.

[0017] During operation, the operator arranges the woven lining between the fixed blade 5 and the cutting blade 7, and turns the control lever 3 to rotate toward the handle 2. At this time, the cross bar 4 located in the hollow circular tube 1 moves toward the right, and at the same time, the other end of the cross bar 4 moves along the slide groove 6, so that the cutting blade 7 rotates to cut the lining between the fixed blade 5 and the cutting blade 7. In addition, in order to ensure the linearity during the cutting process, a sliding card strip can be set on the bottom outer peripheral surface of the hollow circular tube 1, and a guide rail can be set on the table to make the hollow circular tube 1 move along the guide rail.

[0018] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
