[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a base 1, a pressing assembly 2, a conversion assembly 3 and a cutting assembly 4. The conversion assembly 3 and the cutting assembly 4 are arranged on the base 1. The pressing assembly 2 is used to apply a force to the conversion assembly 3. The conversion assembly 3 drives the cutting assembly 4 to move. The direction in which the cutting assembly 4 moves is different from the direction in which the force is applied by the pressing assembly 2. The cutting assembly 4 is used to cut the wire.

[0035] The conversion assembly 3 includes a fixing seat 31 for fixing, the fixing seat 31 is arranged on the base 1, and a fixing hole 32 with a curved surface is arranged on the fixing seat 31. The conversion assembly 3 also includes a first telescopic rod 33, a second telescopic rod 34 and a fan-shaped body 30 with a curved surface, the fan-shaped body 30 is rotatably arranged in the fixing hole 32, the fan-shaped body 30 can rotate in the fixing hole 32, and the first telescopic rod 33 and the second telescopic rod 34 are movably arranged on the fixing seat 31.

[0036] The curved surface of the fan-shaped body 30 fits the curved surface of the fixing hole 32, and an angle is formed between the first telescopic rod 33 and the second telescopic rod 34. The ends of the first telescopic rod 33 and the second telescopic rod 34 are respectively pressed against the two side surfaces of the fan-shaped body 30, and the first telescopic rod 33 is pressed downward. The first telescopic rod 33 is pressed against the first side surface in the rotation direction of the fan-shaped body 30. The first telescopic rod 33 drives the fan-shaped body 30 to rotate, and the curved surface of the fan-shaped body 30 slides on the curved surface of the fixing hole 32, so that the direction of rotation of the fan-shaped body 30 has an arc.

[0037] The second telescopic rod 34 abuts against the second side surface of the sector 30 in the rotation direction, so that when the sector 30 rotates, the sector 30 drives the second telescopic rod 34 to move in a straight line in the horizontal direction.

[0038] The first telescopic rod 33 and the second telescopic rod 34 are not on the same straight line, so the downward movement direction of the first telescopic rod 33 is different from the movement direction of the second telescopic rod 34. In this way, the downward pressure of the first telescopic rod 33 is redirected by the fan-shaped body 30 and converted into the same movement direction as the second telescopic rod 34.

[0039] The cutting assembly 4 includes a slider 41 and a tangent tube 42. The slider 41 is slidably arranged on the base 1. The slider 41 is located on the moving path of the second telescopic rod 34. In this way, when the fan-shaped body 30 drives the second telescopic rod 34 to move, the second telescopic rod 34 will press against the slider 41 and drive the slider 41 to move. The tangent tube 42 is arranged on the slider 41. There is an angle between the extension direction of the tangent tube 42 and the moving direction of the slider 41. A wire is passed through the tangent tube 42, and both ends of the wire are fixed. When the slider 41 drives the tangent tube 42 to move together, the tangent tube 42 can cut the wire into a section, and the length of the wire after cutting is the same as that of the tangent tube 42.

[0040] The conversion assembly 3 also includes a first clamping plate 35 and a second clamping plate 36, which are respectively arranged on both sides of the fixing seat 31, and the first clamping plate 35 and the second clamping plate 36 are connected by screws. The fixing hole 32 is located between the first clamping plate 35 and the second clamping plate 36, so that the fan-shaped body 30 located in the fixing hole 32 cannot fall off from the fixing hole 32.

[0041] The pressing assembly 2 includes a positioning block 21, a pressure rod 22 and a positioning rod 23. The positioning block 21 is set on the base 1. The positioning rod 23 can adopt a screw. The pressure rod 22 is rotatably set on the positioning block 21. In the present application, the pressure rod 22 is rotatably set on the positioning block 21 in a central position. The positioning rod 23 is movably set on the pressure rod 22. The first telescopic rod 33 is located on the moving path of the positioning rod 23. According to the thickness of the wire and the position of the tangent tube 42, the height of the positioning rod 23 on the pressure rod 22 can be adjusted, and the positioning rod 23 can abut against the top end of the first telescopic rod 33.

[0042] The positioning rod 23 is threaded, and a first threaded hole 24 is provided on the pressure rod 22. The positioning rod 23 is sleeved in the first threaded hole 24. The height of the positioning rod 23 on the pressure rod 22 can be adjusted by rotating the positioning rod 23. A first nut 25 is also sleeved on the positioning rod 23. The first nut 25 is located at the upper end of the first threaded hole 24. The lower end surface of the first nut 25 is tightly pressed against the pressure rod 22 to prevent damage to the threads on the positioning rod 23 and the threads in the first threaded hole 24. After the height of the positioning rod 23 is determined, the first nut 25 is tightened. The first nut 25 is abutted against the fixing seat 31, and the first nut 25 increases the force-bearing area.

[0043] The pressing assembly 2 also includes a cam 26 and a rotating shaft 27. The rotating shaft 27 is rotatably set on the base 1, and the cam 26 is set on the rotating shaft 27. The end of the pressure rod 22 is overlapped on the cam 26. The cam 26 and the positioning rod 23 are respectively located at both ends of the pressure rod 22. The rotation of the rotating shaft 27 drives the cam 26 to rotate. When the pressure rod 22 is lifted at the highest point of the cam 26, the positioning rod 23 drops to the lowest position. When the end of the pressure rod 22 is overlapped on the lowest point of the cam 26, the positioning rod 23 rises to the highest position.

[0044] A passive wheel 28 is also provided on the rotating shaft 27, and the base 1 is also provided with a motor 5 and an intermediate shaft 6. The intermediate shaft 6 is rotatably provided on the base 1. In the present application, the driving end of the motor 5 is connected to the intermediate shaft 6 through a belt, and the intermediate shaft 6 is connected to the passive wheel 28 through a belt. The motor 5 drives the intermediate shaft 6 to rotate, and the intermediate shaft 6 drives the passive wheel 28 to rotate, thereby realizing the rotation of the rotating shaft 27.

[0045] Furthermore, a first rotating wheel 61 and a second rotating wheel 62 are respectively provided at both ends of the intermediate shaft 6, the driving end of the motor 5 is connected to the first rotating wheel 61 through a belt, and the second rotating wheel 62 is connected to the driven wheel 28 through a belt.

[0046] The cutting assembly 4 also includes a slide 43 and an elastic member 44. The slide 43 is arranged on the base 1. A slide groove 45 is arranged on the slide 43. The slider 41 is slidably arranged in the slide groove 45. The elastic member 44 is located in the slide groove 45. The elastic member 44 is also located on the sliding path of the slider 41. The slider 41 will squeeze the elastic member 44 when sliding. In this application, the elastic member 44 is a spring.

[0047] When the pressure rod 22 is lifted up at the highest point of the cam 26, the first telescopic rod 33 drives the fan-shaped body 30 to rotate, and the fan-shaped body 30 drives the second telescopic rod 34 to move along a straight line. The second telescopic rod 34 drives the slider 41 to move, and the movement of the slider 41 compresses the elastic member 44. When the end of the pressure rod 22 overlaps the lowest point of the cam 26, the first telescopic rod 33 is reset, and the elastic member 44 drives the second telescopic rod 34 to reset, and the second telescopic rod 34 drives the fan-shaped body 30 to reset.

[0048] A second threaded hole 46 is provided on the slider 41, and a second screw 47 is provided in the second threaded hole 46. The second screw 47 and the elastic member 44 are respectively located on both sides of the slider 41. A second nut 48 is sleeved on the second screw 47. The second screw 47 is located on the moving path of the second telescopic rod 34. The second telescopic rod 34 first drives the second screw 47, and then the slider 41 will move. Because the rotation angle of the fan-shaped body 30 is limited, according to the needs of cutting wire, the slider 41 is required to drive the cutting tube 42 to slide a farther distance. By rotating the second screw 47, the slider 41 can slide farther to prevent the thread on the second screw 47 and the thread in the second threaded hole 46 from being damaged. After the position of the second screw 47 is determined, the second nut 48 is tightened, and the second nut 48 abuts against the slider 41, thereby increasing the force area and protecting the thread on the second screw 47 and the thread in the second threaded hole 46.

[0049] Further, if Figure 4 As shown, the slider 41 is slidably set in the slide groove 45. The slide groove 45 is wide at the bottom and narrow at the top, and the slider 41 is wide at the bottom and narrow at the top. The shape of the slider 41 matches the shape of the slide groove 45, so that the slider 41 can only move in the horizontal direction in the slide groove 45, and the slider 41 cannot move upward to the slide groove 45. The slider 41 is restricted by the slide seat 43. The slider 41 includes a slider 49, and the second screw 47 is set on the slider 49.

[0050] like Figure 5 As shown, in the present application, the fixing seat 31 has a vertical hole 311 and a side hole 312 , the first telescopic rod 33 is slidably disposed in the vertical hole 311 , and the second telescopic rod 34 is slidably disposed in the side hole 312 .

[0051] like Figure 6 As shown, the first end of the second screw 47 abuts against the second telescopic rod 34 , and the second screw 47 is threadedly connected to the slider 49 .

[0052] like Figure 7 As shown, the fan-shaped body 30 is located in the fixing hole 32 , the end of the first telescopic rod 33 abuts against the first side surface of the fan-shaped body 30 in the rotation direction, and the end of the second telescopic rod 34 abuts against the second side of the fan-shaped body 30 in the rotation direction.
