Description

Technical Field

[0001] This utility model relates to the field of wire cutter technology, specifically a wire cutter for power line laying projects. Background Technology

[0002] In existing power line laying projects, the wire cutters widely used are mostly manually operated. This method requires a high level of physical strength from the operators, and prolonged operation can easily lead to fatigue, thus reducing work efficiency. Especially when dealing with a large number of lines to be cut, operators need to apply force frequently, which undoubtedly increases the intensity and difficulty of the work.

[0003] As disclosed in the patent announcement CN222429118U, a wire cutter for power line laying projects includes a connecting plate, a mounting plate, a handle, a drive device, a linkage device, and a wire cutting head. The mounting plate is mounted on the connecting plate; the handle is located at one end of the connecting plate; the drive device includes a drive assembly, which is mounted on the mounting plate; the linkage device includes a gear assembly and two sets of connecting rod assemblies. The beneficial effects of this invention are: the drive device can accurately drive the linkage device to efficiently cut the line, saving working time and reducing the physical burden on operators.

[0004] Although the aforementioned patent uses a motor-driven wire cutting method, the two curved plates (including blades) are in a horizontally parallel state and lack a misalignment angle, which makes it impossible to effectively cut the cable during cutting. Moreover, the completely parallel blades may cause the cable to be squeezed and deformed instead of cut. Utility Model Content

[0011] Preferably, the clamping mechanism further includes a movable block that is laterally fixed between the two connecting parts, and a shaft frame that is fixedly connected to the middle right side of the base and the top plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A power line laying project wire cutter includes a base 1, with a vertical frame 2 fixedly connected to the top right side of the base 1. A horizontal top plate 3 is fixedly connected to the top of the frame 2. Clamping mechanisms are provided on both sides of the top plate 3 and the base 1. The clamping mechanisms include lower clamps 5 symmetrically fixed to the top of both sides of the base 1 and upper clamps 6 movably provided on both sides of the bottom of the top plate 3. Guide grooves 7 are provided on both sides of the frame 2. A connecting piece 8 is fixedly connected to the right side of the upper clamp 6 and slidably connected to the guide groove 7. The clamping mechanism also includes a movable block 9 horizontally fixed between the two connecting pieces 8 and a shaft frame 10 fixedly connected to the middle right side of the base 1 and the top plate 3. A lead screw 11 is rotatably connected between the two shaft frames 10 through a bearing. A crank handle 12 is fixedly connected to the top of the lead screw 11 through the shaft frame 10.

[0026] In this embodiment, the cooperation between the upper and lower clamps 5 and the lead screw driving clamping mechanism provides a stable line fixing effect during the shearing process, solves the problem of incomplete shearing caused by line displacement during shearing, and significantly improves the shearing quality and operational safety.

[0027] like Figure 2 and Figure 4 As shown, the cutter 4 is movably disposed directly below the bottom of the top plate 3. A shearing mechanism is provided between the frame 2 and the cutter 4. The shearing mechanism includes a guide groove 14 opened in the middle of the frame 2. A guide block 15 is fixedly connected to the middle right side of the cutter 4 and slidably connected to the guide groove 14. The shearing mechanism also includes a screw rod 16 threadedly connected to the middle of the top plate 3. A crank handle 17 is fixedly connected to the top of the screw rod 16. The bottom end of the screw rod 16 is rotatably connected to the cutter 4 through a bearing. A clearance groove 13 is opened downward in the middle of the base 1.

[0028] In this embodiment, the vertical shearing motion of the cutter 4 along a precise trajectory is achieved through the combined use of the lead screw drive mechanism and the guide groove. This solves the problem of cable extrusion and deformation caused by the lack of misalignment angle during traditional parallel blade shearing, ensuring the flatness of the shearing surface and the cutting effect.

[0029] Working principle: First, the power line to be cut is placed between the lower clamp 5 on the base 1 and the upper clamp 6 at the bottom of the top plate 3. By rotating the crank handle 12, the lead screw 11 is rotated. The rotation of the lead screw 11 drives the movable block 9 to move up and down along the guide groove 7, thereby driving the connector 8 and the upper clamp 6 to rise and fall synchronously, so that the upper clamp 6 and the lower clamp 5 cooperate to clamp the power line, ensuring the stability of the line during the cutting process. Then, the crank handle 17 is rotated to drive the lead screw 16 to rotate. The rotation of the lead screw 16 pushes the cutter 4 to move down along the guide groove 14 through the bearing. The guide block 15 slides in the guide groove 14 to keep the movement trajectory of the cutter 4 stable. The cutter 4 moves down to cooperate with the relief groove 13 in the middle of the base 1, completing the cutting operation of the power line.

[0030] It should be noted that the upper clamp 6 and the lower clamp 5 are V-groove structures.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
