Description

Technical Field

[0001] This invention relates to the field of manual hardware tools, and in particular to a labor-saving cutting method for wire cutters. Background Technology

[0002] Currently, wire cutters are mainly used to cut electrical wires or metal wires. However, they require a lot of force to cut them. Traditional wire cutters, such as the patent application with publication number CN221047417U entitled "A Force-Saving Cutting Method for Wire Cutters," mainly achieve the effect of saving force by adding a telescopic tube to the handle. By adjusting the length of the telescopic tube, the force-saving effect is achieved. However, this structure is relatively bulky. Although the telescopic rod does save some force when extended, the operating radius is large and it is not easy to operate. The hinge between the handle and the head is only transmitted through a single lever. Prolonged use will still lead to hand fatigue, which is time-consuming and laborious. At present, there is no good way to solve the above problems.

[0003] In summary, how to effectively solve the problem of labor-saving cutting with wire cutters has become a pressing technical challenge for the industry. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a labor-saving cutting method for wire cutters, which solves the problems of complex structure, difficulty in operation, and failure to achieve true labor-saving effect due to the transmission between the handle and the head via a single lever.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A labor-saving cutting method for wire cutters, the wire cutters include a left blade, a right blade, an upper pressure plate, a lower pressure plate, a left clamp body and a right clamp body. The front part of the left blade is hinged to the upper pressure plate and the lower pressure plate by rivet A, the rear end of the left blade is hinged to the front end of the lower connecting plate by rivet B, and the rear end of the lower connecting plate is hinged to the left clamp body by rivet C. The front part of the right blade is hinged to the upper pressure plate and the lower pressure plate by rivet D, the rear end of the right blade is hinged to the front end of the upper connecting plate by rivet E, and the rear end of the upper connecting plate is hinged to the right clamp body by rivet F. The upper connecting plate and the lower connecting plate are hinged together by rivets G. The teeth of the upper connecting plate mesh with the teeth at the front end of the left clamp body, and the teeth of the lower connecting plate mesh with the teeth at the front end of the right clamp body. When the left clamp is gripped inward, the rear end of the left clamp moves inward and the front end moves outward under the action of rivet C. The teeth at the front end of the left clamp drive the teeth of the upper connecting plate to rotate clockwise. Under the action of rivet G, the rivet E on the other side of the upper connecting plate drives the rear end of the right blade to move outward. Under the action of rivet D, the front end of the right blade moves inward. Rivet C acts as a primary lever on the left clamp and rivet D acts as a secondary lever on the right blade, effectively achieving a labor-saving effect. When the right clamp is gripped inward, the rear end of the right clamp moves inward under the action of rivet F, and the front end moves outward. The teeth at the front end of the right clamp drive the teeth of the lower connecting plate to rotate clockwise. Under the action of rivet G, rivet B on the other side of the lower connecting plate drives the rear end of the left blade to move outward. Under the action of rivet A, the front end of the left blade moves inward. Rivet F acts as a primary lever on the right clamp, and rivet A acts as a secondary lever on the left blade, effectively achieving a labor-saving effect.

[0006] The left and right blades engage with each other through inwardly protruding teeth.

[0007] The distance between rivet A and the rear end of the left blade is greater than the distance between rivet A and the front end of the left blade.

[0008] The distance between the rivet D and the rear end of the right blade is greater than the distance between the rivet D and the front end of the right blade.

[0009] The distance between the rivet C and the rear end of the left clamp body is greater than the distance between the rivet C and the front end of the left clamp body.

[0010] The distance between the rivet F and the rear end of the right clamp body is greater than the distance between the rivet F and the front end of the right clamp body.

[0011] The tooth shape and number of teeth between the upper connecting plate and the left clamp body, and between the lower connecting plate and the right clamp body, are consistent.

[0012] The present invention adopts the above-described solution and has the following beneficial effects: By adding a lower connecting plate and an upper connecting plate, the front end of the lower connecting plate is hinged to the left blade via rivet B, and the rear end of the lower connecting plate is hinged to the left clamp body via rivet C. The front end of the upper connecting plate is hinged to the right blade via rivet E, and the rear end of the upper connecting plate is hinged to the right clamp body via rivet F. The upper and lower connecting plates are also hinged together via rivet G. Rivets C and F act as primary levers on the left and right clamp bodies, respectively. Simultaneously, the left clamp body and the upper connecting plate transmit power through teeth, and the right clamp body and the lower connecting plate transmit power through teeth. The tooth ratio between the teeth allows for the output of greater torque. In addition, rivets A and D act as secondary levers on the left and right blades, respectively. The wire cutter of this invention integrates primary levers, toothed transmission, and secondary levers into one unit, effectively achieving a labor-saving effect. It also features a compact structure, a small operating radius, and ease of operation, achieving the purpose of labor-saving workpiece cutting. Attached Figure Description

[0019] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0020] like Figure 1-5 As shown, a labor-saving cutting method for wire cutters is provided. The wire cutters include a left blade 1, a right blade 2, an upper pressure plate 3, a lower pressure plate 4, a left clamp body 5, and a right clamp body 6. The front part of the left blade 1 is hinged to the upper pressure plate 3 and the lower pressure plate 4 by rivet A7. The rear end of the left blade 1 is hinged to the front end of the lower connecting plate 8 by rivet B9. The rear end of the lower connecting plate 8 is hinged to the left clamp body 5 by rivet C10. The front part of the right blade 2 is hinged to the upper pressure plate 3 and the lower pressure plate 4 by rivet D11, the rear end of the right blade 2 is hinged to the front end of the upper connecting plate 12 by rivet E13, and the rear end of the upper connecting plate 12 is hinged to the right clamp body 6 by rivet F14. The upper connecting plate 12 and the lower connecting plate 8 are hinged together by rivets G15. The teeth of the upper connecting plate 12 mesh with the teeth at the front end of the left clamp body 5, and the teeth of the lower connecting plate 8 mesh with the teeth at the front end of the right clamp body 6. When the left clamp body 5 is gripped inward, under the action of rivet C10, the rear end of the left clamp body 5 moves inward and the front end moves outward. The teeth 16 at the front end of the left clamp body 5 drive the teeth 16 of the upper connecting plate 12 to rotate clockwise. Under the action of rivet G15, the rivet E13 on the other side of the upper connecting plate 12 drives the rear end of the right blade 2 to move outward. Under the action of rivet D11, the front end of the right blade 2 moves inward. Rivet C10 acts as a first-level lever on the left clamp body 5, and rivet D11 acts as a second-level lever on the right blade 2, effectively achieving a labor-saving effect. When the right clamp body 6 is gripped inward, under the action of rivet F14, the rear end of the right clamp body 6 moves inward and the front end moves outward. The teeth 16 at the front end of the right clamp body 6 drive the teeth 16 of the lower connecting plate 8 to rotate clockwise. Under the action of rivet G15, the rivet B9 on the other side of the lower connecting plate 8 drives the rear end of the left blade 1 to move outward. Under the action of rivet A7, the front end of the left blade 1 moves inward. Rivet F14 acts as a primary lever on the right clamp body 6, and rivet A7 acts as a secondary lever on the left blade 1, effectively achieving a labor-saving effect.

[0021] The left blade 1 and the right blade 2 are engaged by inwardly protruding teeth 16. The teeth 16 provide support between the left blade 1 and the right blade 2 and prevent the left blade 1 and the right blade 2 from slipping vertically. At the same time, the upper pressure plate 3 and the lower pressure plate 4 prevent the left blade 1 and the right blade 2 from shifting back and forth.

[0022] The distance between rivet A7 and the rear end of the left blade 1 is greater than the distance between rivet A7 and the front end of the left blade 1, and the distance between rivet D11 and the rear end of the right blade 2 is greater than the distance between rivet D11 and the front end of the right blade 2. Rivet A7 and rivet D11 act as secondary levers on the left blade 1 and the right blade 2, respectively, to achieve a labor-saving effect.

[0023] The distance between rivet C10 and the rear end of the left clamp body 5 is greater than the distance between rivet C10 and the front end of the left clamp body 5, and the distance between rivet F14 and the rear end of the right clamp body 6 is greater than the distance between rivet F14 and the front end of the right clamp body 6. Rivet C10 and rivet F14 act as a first-level lever on the left clamp body 5 and the right clamp body 6, respectively, to achieve a labor-saving effect.

[0024] The teeth between the upper connecting plate 12 and the left clamp 5, and the teeth 16 between the lower connecting plate 8 and the right clamp 6, have the same tooth shape and number to ensure synchronous operation on both sides.

[0025] Working principle: In use, grip the left clamp 5 and right clamp 6 inwards. Under the action of rivet C10, the rear end of the left clamp 5 moves inwards, and the front end moves outwards. The teeth 16 at the front end of the left clamp 5 drive the teeth 16 of the upper connecting plate 12 to rotate clockwise. Under the action of rivet G15, the rivet E13 on the other side of the upper connecting plate 12 drives the rear end of the right blade 2 to move outwards, and the front end of the right blade 2 moves inwards under the action of rivet D11. Similarly, under the action of rivet... Under the action of F14, the rear end of the right clamp body 6 moves inward and the front end of the right clamp body 6 moves outward. The teeth 16 at the front end of the right clamp body 6 drive the teeth 16 of the lower connecting plate 8 to rotate clockwise. Under the action of rivet G15, the rivet B9 on the other side of the lower connecting plate 8 drives the rear end of the left blade 1 to move outward. Under the action of rivet A7, the front end of the left blade 1 moves inward. With the cooperation of the left blade 1 and the right blade 2, the wire or metal wire can be cut. During the cutting process, rivets C10 and F14 act as primary levers on the left jaw 5 and right jaw 6, respectively. At the same time, the left jaw 5 and the upper connecting plate 12 transmit power through the teeth 16, and the right jaw 6 and the lower connecting plate 8 transmit power through the teeth 16. The tooth ratio between the teeth 16 can output greater torque. In addition, rivets A7 and D11 act as secondary levers on the left blade 1 and right blade 2, respectively. By integrating the primary levers, tooth transmission, and secondary levers into one unit, a labor-saving effect can be effectively achieved.

[0026] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0027] Any aspects of this invention not described in detail are well-known to those skilled in the art.
