Description

Technical Field

[0001] The present application relates to the technical field of scissors, and in particular to a pair of clothing processing and cutting scissors. Background Art

[0002] Manual cutting of clothing is an important part of the clothing production process. It involves cutting the fabric precisely according to the design drawings or patterns to ensure the perfect structure, size, style and details of the clothing.

[0003] At present, the cutting scissors used for garment processing include two cutting blades, a connecting hinge connecting the blades, and a handle arranged at the end of the blades. However, in actual applications, for some fixed cutting sizes, the processing personnel are usually required to repeatedly cut with the scissors at a fixed position, so the cutting size usually needs to be manually visually controlled, so that the cutting gap obtained by the final cutting is likely to deviate from the actual required size. Utility Model Content

[0004] In order to adjust the cutting distance of the scissors each time they cut, the present application provides a clothing processing and cutting pair of scissors.

[0005] The present application provides a clothing processing cutting knife adopting the following technical solution:

[0006] A pair of clothing processing cutting knives comprises a first blade, a second blade and a connecting piece connecting the two blades, wherein the first blade is provided with a first shearing surface and a first handle portion at both ends, and the second blade is provided with a second shearing surface and a second handle portion at both ends, and the first handle portion is slidably mounted with an anti-rotation structure for abutting against the second handle portion, and the connecting piece is provided with an abutting piece on the side facing the blade surface, and when the first blade is rotated so that the anti-rotation structure abuts against the second handle portion, the shearing surface stops shearing.

[0007] By adopting the above technical solution, when using the above-mentioned cutting pair to cut cloth, the anti-rotation structure is moved to the required position according to the cutting length, and the two blades are rotated to open so that the cloth is inserted between the two cutting surfaces, so that the cloth abuts against the abutment sheet, and then the first handle part is rotated. When the anti-rotation structure abuts against the second handle part, it limits the rotation of the two blades and stops cutting. The setting of the anti-rotation structure can limit the cutting and ensure the consistency of the cutting length on the cloth under the abutment of the abutment sheet.

[0008] Optionally, the anti-rotation structure includes a movable frame, a limiting abutment column for abutting the second handle portion, and a locking member for fixing the movable frame, the first handle portion is provided with a sliding shaft along the length direction, and the movable frame has a sliding hole that slides with the sliding shaft.

[0009] By adopting the above technical solution, the composition of the anti-rotation structure is disclosed, the movable frame and the first handle part can slide, the limiting abutment column is used to abut against the second handle part, and the locking member is used to lock the movable frame on the sliding shaft, thereby reducing the probability of the movable frame moving after moving to the desired position.

[0010] Optionally, the movable frame and the sliding shaft are rotatably matched, and the inner wall of the sliding hole is provided with an arc groove along the circumferential direction, and the sliding shaft is provided with a positioning ridge on the side facing the second handle part and along the length direction. When the movable frame is rotated so that one end of the arc groove abuts against the positioning ridge, the end of the limit abutment column corresponds to the second handle part.

[0011] By adopting the above technical solution, the rotational coordination of the movable frame and the sliding shaft makes it possible to move the movable frame to the side of the first handle portion when the anti-rotation mechanism is not needed to limit the rotation of the blade, so that the planes where the movable frame and the first handle portion are located are perpendicular, thereby ensuring the normal use of the cutting shears; through the coordination of the arc groove and the positioning ridge, when the anti-rotation mechanism is needed to limit the rotation, it can be ensured that the limiting abutment column corresponds to the second handle portion.

[0012] Optionally, the inner wall of the abutting groove is evenly provided with anti-slip patterns abutting against the first convex ridge.

[0013] By adopting the above technical solution and providing the anti-slip texture, a friction effect is exerted on the rotation of the mobile frame, thereby improving the stability of the mobile frame.

[0014] Optionally, an inner screw hole is formed at the end of the position limiting abutment column, and an extension column is threadedly provided at the inner screw hole of the position limiting abutment column.

[0015] By adopting the above technical solution and setting the extension column, the overall length of the limiting abutment column can be extended, thereby increasing the range in which the anti-rotation structure can limit the position.

[0016] Optionally, a side of the first handle portion facing the second handle portion has an abutment groove for the extension column to abut against.

[0017] By adopting the above technical solution and setting the abutment groove, when the extension column abuts against the second handle portion, the stability of the anti-rotation structure is further increased.

[0018] Optionally, the locking member is a locking bolt, the movable frame has a locking through hole connected to the sliding hole, and the side wall of the sliding shaft is provided with a plurality of locking screw holes corresponding to the locking through hole at intervals along the axial direction.

[0019] By adopting the above technical solution, a locking member is disclosed. After the movable frame is moved to the desired position, the locking bolt is threadedly matched with the locking screw hole and further inserted into the locking hole to achieve locking and fixing of the movable frame and the first handle portion.

[0020] Optionally, a fixed baffle is rotatably provided at the end of the second handle portion, and one end of the sliding shaft abuts against the fixed baffle.

[0021] By adopting the above technical solution and the rotatable installation of the fixed baffle, the anti-rotation mechanism can be removed from the first handle portion, which is convenient for replacing and installing the anti-rotation mechanism. At the same time, the cutting shears with the anti-rotation structure removed can be used as conventional cutting shears.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present invention can limit the cutting by setting the anti-rotation structure and the abutment sheet, and at the same time, under the abutment of the abutment sheet, ensure that the cutting length of the fabric is consistent each time;

[0024] 2. The application can ensure the correspondence between the limit abutment column and the second handle part through the cooperation of the arc groove and the positioning convex ridge, and the cutting knife can be used normally when the anti-rotation structure is not used;

[0025] 3. The present application further increases the stability of the anti-rotation structure when the extension column abuts against the second handle portion by setting the abutment adjustment groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a pair of clothing processing cutting knives.

[0033] Reference Figure 1 A clothing processing cutting knife comprises a first blade 1, a second blade 2, a connecting piece 3 connecting the two blades, and an anti-rotation structure 4 for limiting the rotation of the blades.

[0034] The first blade 1 is provided with a first shearing surface 11 and a first handle portion 12 at both ends. The second blade 2 is provided with a second shearing surface 21 and a second handle portion 22 at both ends. Both handle portions are formed integrally with the corresponding blades. The connecting member 3 is a hinge in the prior art. Among them, the first blade 1 and the second blade 2 are also provided with a contact piece 15 on the side of the connecting member 3 close to the shearing surface, and the contact piece 15 is connected to the blades by plugging and disassembling the blades. Each time the cloth is cut, it is inserted between the two shearing surfaces, and the cutting is started after the cloth contacts the contact piece 15.

[0035] Reference Figure 2 and Figure 3 The anti-rotation structure 4 includes a moving frame 41, a limiting abutment column 42 and a locking member 43. A sliding shaft 13 is fixedly arranged along the length direction of the first handle portion 12 on one side facing the second handle portion 22. The moving frame 41 has a sliding hole 411 sleeved on the sliding shaft 13, so that the moving frame 41 can slide back and forth along the length direction of the first handle portion 12.

[0036] The radial cross section of the sliding shaft 13 is circular, and the sliding hole 411 is adapted to the sliding shaft 13, so the movable frame 41 is also rotatably matched with the first handle portion 12. The movable frame 41 is provided with an arc groove 412 along the circumferential direction on the inner wall of the sliding hole 411, and the arc of the arc groove 412 is 90°. The sliding shaft 13 is integrally provided with a positioning convex ridge 131 along the length direction on the side facing the second handle portion 22.

[0037] The positioning rib 131 is used to cooperate with the arc groove 412. When one end of the arc groove 412 abuts against the positioning rib 131, the axis of the limiting abutting column 42 is in the plane of the first handle portion 12. When the other end of the arc groove 412 abuts against the positioning rib 131, the axis of the limiting abutting column 42 is perpendicular to the plane of the first handle. Among them, the mobile frame 41 is also uniformly provided with anti-skid patterns 4121 along the circumferential direction on the inner wall of the arc groove 412. The abutment and cooperation between the anti-skid patterns 4121 and the positioning rib 131 can increase the friction force when the mobile frame 41 rotates, so that when cutting does not require limiting, the probability of the mobile frame 41 rotating is reduced, and the stability of the mobile frame 41 when not in use is improved.

[0038] Combination Figure 4 The limiting abutting column 42 is integrally arranged on the side wall of the movable frame 41, and is used to abut against the inner side of the second handle portion 22. An inner screw hole 421 is provided at the end of the limiting abutting column 42, and an extension column 44 is threadedly installed at the inner screw hole 421 of the limiting abutting column 42. The end of the extension column 44 is an arc-shaped protrusion. The inner side of the second handle portion 22 has an abutting groove 221 along the length direction for the end of the extension column 44 to abut.

[0039] A scale line (not shown) may be provided on the side of the first handle portion 12 close to the sliding shaft 13 to indicate the range of limited rotation. The range of the scale line is the data when the extension column 44 and the inner screw hole 421 are fully matched.

[0040] The locking member 43 is a locking bolt. The movable frame 41 has a locking through hole 413 that penetrates and connects to the sliding hole 411. The side wall of the sliding shaft 13 is evenly spaced along the length direction to form locking screw holes 132 corresponding to the locking through holes 413. The locking screw holes 132 and the positioning ridges 131 are staggered.

[0041] A positioning rod 23 is provided on the side of the second handle portion 22 away from the connecting member 3. The positioning rod 23 and the second handle portion 22 are integrally formed, and the end of the positioning rod 23 has an arc-shaped opening that matches the sliding shaft 13. When the arc-shaped opening and the sliding shaft 13 abut against each other, the two blades are in an overlapping state. The anti-rotation mechanism is integrally slidably arranged between the positioning rod 23 and the connecting member 3, that is, an abutting groove 221 is provided between the positioning rod 23 and the connecting member 3.

[0042] In order to facilitate the disassembly of the anti-rotation structure 4, a fixed baffle 14 is rotatably provided at the end of the first handle portion 12. One end of the sliding shaft 13 abuts against the fixed baffle 14, and the fixed baffle 14 can be rotated outward away from the connecting member 3 so that the movable frame 41 can be disassembled from the fixed baffle 14.

[0043] The implementation principle of the clothing processing cutting knife in the embodiment of the present application is as follows: before cutting, the frame 41 is moved back and forth according to the required cutting length, and after moving to the required cutting length, the movable frame 41 is rotated so that the positioning ridge 131 abuts against one end of the arc groove 412, and then locked and fixed by a locking bolt;

[0044] Insert the cloth between the first cutting surface 11 and the second cutting surface 21, and start cutting after one end of the cloth abuts against the abutting piece. The user holds the two handles until the extension column 44 abuts against the abutting groove 221, and the blade can no longer rotate, and cutting is completed.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
