Description

Technical Field

[0001] This utility model relates to the field of hand tool technology, and in particular to a combination wire cutter. Background Technology

[0002] Wire cutters are a type of tool specifically designed for cutting electrical wires and thicker metal wires. They are highly practical and widely used, especially suitable for professionals such as electricians and repairmen. Depending on the usage environment and the characteristics of the user group, wire cutter manufacturers also produce different types of wire cutters.

[0003] For example, a wire cutter disclosed in Chinese Patent Publication No. CN217412636U includes: a blade, a pin, a pressure plate, a bolt, a nut, a screw, a nut, a left connecting arm, a middle connecting arm, a handle, a rubber handle, and a fastening screw. It also includes a right connecting arm, an adjusting screw, an elastic element, and a steel ball. The upper middle part of the right connecting arm is provided with a threaded hole, and the head of the adjusting screw is provided with a countersunk hole. The countersunk hole contains an elastic element. One end of the elastic element contacts the bottom of the countersunk hole of the head of the adjusting screw, and the other end contacts the steel ball. The steel ball contacts the middle connecting arm.

[0004] When workers use existing large wire cutters to cut thicker metal wires, due to the large weight of the wire cutters, they usually stand the large wire cutters on their side on the ground and grasp one of the handles to perform the cutting work. However, since the handle of the large wire cutters is cylindrical, when the worker stands the large wire cutters on their side to perform the cutting work, the wire cutters are subjected to non-vertical downward pressure and will swing to both sides, thus affecting the worker's efficiency in cutting thicker metal wires. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the handle of large wire cutters is cylindrical, causing the wire cutters to swing to both sides when the worker stands on the side to cut the wires, due to the non-vertical downward pressure, thus affecting the worker's efficiency in cutting thicker metal wires. Therefore, a combined wire cutter is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined wire cutter, comprising blades and a footplate, with clamps threadedly connected to both sides of the two blades, a support arm rotatably engaged at one end of each blade, a handle fixedly connected to one end of the support arm, a telescopic rod movably engaged on the inner side of the handle, a grip fixedly connected to one end of the telescopic rod, rectangular grooves formed on both sides of the handle, a plurality of first-order limiting circular grooves evenly formed on the inner side of the rectangular grooves, a plurality of second-order limiting circular grooves evenly formed on one side of the telescopic rod, a first-order positioning bolt movably engaged on the inner side of the first-order limiting circular groove, a mounting bracket movably engaged on the outer side of the first-order positioning bolt, the bottom end of the mounting bracket fixedly connected to one end of the footplate, and the other end of the first-order positioning bolt threadedly connected to the inner side of one end of the footplate.

[0007] Preferably, a mounting groove is provided on one side of one end of the clamp handle, and a positioning clip is movably engaged on the inner side of the mounting groove.

[0008] Preferably, one end of the positioning clip is threadedly connected to a No. 2 positioning bolt, and one end of the No. 2 positioning bolt is threadedly connected to the outside of the pliers handle.

[0009] Preferably, the inner side of the positioning card is symmetrically fixedly connected with a limiting block.

[0010] Preferably, a limiting groove is symmetrically provided on one side of the telescopic rod, and one end of the limiting block is movably engaged inside the limiting groove.

[0011] Preferably, a third positioning bolt is movably engaged on the inner side of the first limiting groove, and a limiting nut is threadedly connected to one end of the third positioning bolt.

[0012] Preferably, one end of the third positioning bolt is movably engaged inside the second limiting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the clamp handle is fixed to one side of the foot plate by using a No. 1 positioning bolt. When the worker needs to cut a thicker metal wire, one of the clamp handles of the combined wire cutter is placed at the lower end of the mounting frame. The two No. 1 positioning bolts are passed through the No. 1 and No. 2 limiting round grooves and rotated so that one end of them is threaded to one end of the foot plate, thereby fixing the clamp handle to one side of the foot plate. This prevents the clamp handle from wobbling left and right when the worker applies pressure to it, thus improving the worker's efficiency in cutting metal wire.

[0015] 2. In this utility model, by movably engaging the telescopic rod on the inside of the pliers handle, when the worker needs to cut a thicker metal wire, the limiting nut is rotated to remove the No. 3 positioning bolt from the inside of the No. 1 and No. 2 limiting circular grooves, and then the telescopic rod is pulled outward from one end of the pliers handle to a specified length, thereby extending the length of the pliers handle, so that the worker can save effort when cutting a thicker metal wire.

[0023] Example 1

[0024] like Figure 1-4As shown, this utility model provides a combined wire cutter, including blades 1 and footplates 5. Clamping plates 2 are threaded to both sides of the two blades 1. Support arms 3 are rotatably engaged at one end of each blade 1. A handle 4 is fixedly connected to one end of each support arm 3. A telescopic rod 41 is movably engaged on the inner side of the handle 4. A grip 6 is fixedly connected to one end of the telescopic rod 41. Rectangular grooves 42 are formed on both sides of the handle 4. Several first-positioning circular grooves 43 are evenly formed on the inner side of the rectangular grooves 42. Several second-positioning circular grooves 411 are evenly formed on one side of the telescopic rod 41. A first-positioning bolt 44 is movably engaged on the inner side of the first-positioning circular groove 43. An mounting bracket 51 is movably attached to the outer side. The bottom end of the mounting bracket 51 is fixedly connected to one end of the footplate 5. The other end of the first positioning bolt 44 is threadedly connected to the inner side of one end of the footplate 5. An installation groove 45 is provided on one side of one end of the clamp handle 4. A positioning clip 46 is movably attached to the inner side of the installation groove 45. A second positioning bolt 461 is threadedly connected to one end of the positioning clip 46. One end of the second positioning bolt 461 is threadedly connected to the outer side of the clamp handle 4. Limiting blocks 462 are symmetrically fixedly connected to the inner side of the positioning clip 46. A limiting groove 412 is symmetrically provided on one side of the telescopic rod 41. One end of the limiting block 462 is movably attached to the inside of the limiting groove 412.

[0025] The specific settings and functions of this embodiment are described below. When a worker needs to cut a thicker metal wire, one of the clamp handles 4 of the combined wire cutter is placed at the lower end of the mounting bracket 51. Two No. 1 positioning bolts 44 are passed through the No. 1 limiting circular groove 43 and the No. 2 limiting circular groove 411 and rotated so that one end of them is threaded to one end of the foot plate 5, thereby fixing the clamp handle 4 to one side of the foot plate 5. This prevents the clamp handle 4 from wobbling left and right when the worker applies pressure to it, thus improving the efficiency of the worker in cutting the metal wire. When the telescopic rod 41 slides inside the clamp handle 4, the limiting block 462 slides inside the limiting groove 412 to limit the telescopic rod 41 and prevent it from sliding out from one end of the clamp handle 4.

[0026] Example 2

[0027] like Figure 1-4 As shown, a telescopic rod 41 is movably engaged on the inner side of the pliers handle 4. One end of the telescopic rod 41 is fixedly connected to a handle 6. Rectangular grooves 42 are provided on both sides of the pliers handle 4. Several first-positioning circular grooves 43 are evenly provided on the inner side of the rectangular grooves 42. Several second-positioning circular grooves 411 are evenly provided on one side of the telescopic rod 41. A third-positioning bolt 47 is movably engaged on the inner side of the first-positioning circular groove 43. One end of the third-positioning bolt 47 is threadedly connected to a limit nut 471. The outer end of the third-positioning bolt 47 is movably engaged inside the second-positioning circular groove 411.

[0028] The overall effect of this embodiment is that when a worker needs to cut a thicker metal wire, the limiting nut 471 is rotated to remove the No. 3 positioning bolt 47 from the inside of the No. 1 limiting groove 43 and the No. 2 limiting groove 411. Then, the telescopic rod 41 is pulled outward from one end of the handle 4 to a specified length, thereby extending the length of the handle 4. This allows the worker to save effort when cutting a thicker metal wire. The No. 3 positioning bolt 47 is then inserted back into the inside of the No. 1 limiting groove 43 and the No. 2 limiting groove 411 to limit and fix the telescopic rod 41.

[0029] The usage and working principle of this device are as follows: When a worker needs to cut a thicker metal wire, rotate the limiting nut 471 to remove the No. 3 positioning bolt 47 from the inside of the No. 1 limiting groove 43 and the No. 2 limiting groove 411. Then, pull the telescopic rod 41 outward from one end of the handle 4 to a specified length, thereby extending the length of the handle 4. Place one of the handles 4 of this combination wire cutter at the lower end of the mounting bracket 51. Pass the two No. 1 positioning bolts 44 through the No. 1 limiting groove 43 and the No. 2 limiting groove 411 and rotate them so that one end of them is threaded to one end of the foot plate 5, thereby fixing the handle 4 to one side of the foot plate 5.
