Description

Technical Field

[0001] This utility model relates to the field of electrician's pliers technology, specifically a multifunctional electrician's pliers for substation maintenance. Background Technology

[0002] Electrician's pliers are a general term for pliers with insulated handles specifically designed for electrical work. Electrician's pliers are mainly used for cutting, stripping, clamping and bending wires and cables. Therefore, electrician's pliers are mainly used for substation maintenance, electrical installation, and the repair and maintenance of wires and cables.

[0003] When using electrician's pliers to inspect and repair wires and cables, routine operations such as bending and clamping are required. However, most existing electrician's pliers lack a locking function, necessitating continuous manual pressure on the handles to perform these operations. This not only increases the electrician's physical exertion, leading to hand fatigue and reduced work efficiency over extended periods, but also makes it difficult to maintain stability and precision during continuous force application, potentially causing unnecessary damage to the cables and even posing safety hazards. Therefore, a multi-functional substation maintenance electrician's pliers is proposed to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional electrician's pliers for substation maintenance, featuring a locking function and other advantages. This solves the problem that when using electrician's pliers to inspect and repair wires and cables, conventional operations such as bending and clamping are required. Most existing electrician's pliers lack a locking function, necessitating continuous manual pressure on the handles to perform these operations. This not only increases the electrician's physical exertion, leading to hand fatigue and reduced work efficiency over extended periods, but also makes it difficult to maintain stability and accuracy during continuous force application, potentially causing unnecessary damage to the cables and even posing safety hazards.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multifunctional electrician's pliers for substation maintenance includes two plier handles and two plier heads. A support block is fixedly connected to the bottom of the plier handle. Long shafts are rotatably connected to the front and back of the support block. Bases are rotatably connected to the outer sides of the two long shafts. Springs are fixedly connected inside the two bases. Pressure blocks are fixedly connected to the top of the two springs. A hanging block is fixedly connected to the top of the two pressure blocks. Three force-bearing blocks are fixedly connected to the bottom of the top plier handle.

[0008] The beneficial effects of this utility model are as follows: through the coordinated cooperation of the support block, long shaft, base, spring, pressure block, hanging block and force-bearing block, the locking function is realized. When it is necessary to continuously clamp or bend the cable, the hanging block can engage with the force-bearing block at different positions, eliminating the need for continuous manual pressure on the handle, greatly reducing the physical exertion of electricians, avoiding hand fatigue caused by long-term operation, and effectively improving work efficiency. At the same time, the locking state can ensure the stability and accuracy of operation, reduce unnecessary damage to the cable, and reduce operational safety hazards.

[0009] This multi-functional electrician's pliers for substation maintenance has the advantage of a locking function.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, each of the two clamp handles is fixedly connected to a clamp head on its left side, and the two clamp heads are rotatably connected to the same shaft inside.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by rotating the two clamp heads together through the pivot, the clamp heads can be flexibly opened and closed around the pivot, providing a structural basis for cutting, clamping and other operations, and ensuring that the opening and closing angle of the clamp heads can be adjusted as needed during operation.

[0013] Furthermore, stripping blocks are fixedly connected to the opposite sides of the two pliers heads, rubber sleeves are fixedly connected to the outer sides of the two pliers handles, and the three force-bearing blocks are all arranged in an L-shape.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the wire stripping block allows electricians' pliers to complete wire stripping operations without additional tools, enhancing the versatility of the tool. The rubber sleeve improves the comfort of holding the tool and enhances the insulation performance to ensure operational safety. Furthermore, the L-shaped force block can better cooperate with the hanging block to achieve stable triggering of the locking function.

[0015] Furthermore, the outer sides of both rubber sleeves are knurled, and both clamp handles are arc-shaped.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the knurled rubber sleeve can increase the friction between the hand and the pliers handle, effectively preventing the tool from slipping during operation and improving the stability of operation. The arc-shaped pliers handle conforms to the ergonomic design, fits the hand grip posture, and reduces hand fatigue caused by long-term operation.

[0017] Furthermore, a pressure block is fixedly connected to one side of each of the two clamp heads, and a tooth block is fixedly connected to one side of each of the two clamp heads.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the toothed blocks can enhance the clamping force on the cable, prevent the cable from slipping during the clamping process, and improve the reliability of the operation.

[0019] Furthermore, each of the two long shafts is fixedly connected to a cap at one end, and both caps are trapezoidal in shape.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the trapezoidal cap can limit the long shaft, prevent the long shaft from falling out of the support block, ensure the stability of the connection of the locking mechanism and avoid the long shaft from loosening and affecting the normal use of the tool.

[0026] 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.

[0027] In the embodiments, by Figure 1-4 The present invention provides a multifunctional electrician's pliers for substation maintenance. The present invention includes two plier handles 1 and two plier heads 2. The bottom of the bottom plier handle 1 is fixedly connected to a support block 3. The front and back of the support block 3 are rotatably connected to long shafts 4. The outer sides of the two long shafts 4 are rotatably connected to bases 5. The inside of the two bases 5 is fixedly connected to springs 6. The top of the two springs 6 is fixedly connected to pressure blocks 7. The top of the two pressure blocks 7 is fixedly connected to the same hanging block 8. The bottom of the top plier handle 1 is fixedly connected to three force-bearing blocks 9.

[0028] The left side of each of the two pliers handles 1 is fixedly connected to a pliers head 2, and the two pliers head 2 are rotatably connected to the same rotating shaft 10.

[0029] The two clamp heads 2 are rotatably connected by the rotating shaft 10, so that the clamp heads 2 can open and close flexibly around the rotating shaft 10, providing a structural basis for cutting, clamping and other operations, and ensuring that the opening and closing angle of the clamp heads 2 can be adjusted as needed during operation;

[0030] A stripping block 11 is fixedly connected to one side of each of the two pliers heads 2, and a rubber sleeve 12 is fixedly connected to the outside of each of the two pliers handles 1. The three force blocks 9 are all arranged in an L-shape.

[0031] The wire stripping block 11 allows electricians' pliers to strip wires without additional tools, enhancing the tool's versatility. The rubber sleeve 12 improves grip comfort and enhances insulation performance to ensure operational safety. The L-shaped force block 9 can better cooperate with the hanging block 8 to achieve stable triggering of the locking function.

[0032] The outer sides of both rubber sleeves 12 are knurled, and both clamp handles 1 are arc-shaped.

[0033] The knurled rubber sleeve 12 increases the friction between the hand and the handle 1, effectively preventing the tool from slipping during operation and improving the stability of operation. The curved handle 1 conforms to the ergonomic design, fits the hand grip posture, and reduces hand fatigue caused by long-term operation.

[0034] A pressure block 13 is fixedly connected to one side of each of the two pliers 2, and a tooth block 14 is fixedly connected to one side of each of the two pliers 2.

[0035] The toothed block 14 can enhance the clamping force on the cable, prevent the cable from slipping during clamping, and improve the reliability of operation;

[0036] One end of each of the two long shafts 4 is fixedly connected to a cap 15, and both caps 15 are arranged in a trapezoidal shape.

[0037] The trapezoidal cap 15 can limit the long shaft 4, preventing it from falling out of the support block 3, ensuring the stability of the connection of the locking mechanism and avoiding the impact of the long shaft 4 loosening on the normal use of the tool.

[0038] Working principle:

[0039] Step 1: Operation preparation and clamping the cable. Hold the pliers handle 1 with the rubber sleeve 12, and control the opening and closing of the two pliers heads 2 through the rotating shaft 10. Place the cable to be processed between the teeth 14 of the pliers head 2. At this time, the arc-shaped pliers handle 1 fits the hand, and the knurled rubber sleeve 12 increases the friction to ensure a stable grip. The teeth 14 can initially clamp the cable to prevent it from slipping.

[0040] Step 2: When it is necessary to continuously clamp or bend the cable, forcefully close the clamp handle 1 and pull the hanging block 8, so that the hanging block 8 drives the two pressure blocks 7 to move, and then the two pressure blocks 7 drive the two springs 6 to stretch. When the hanging block 8 moves to the horizontal line that matches the force block 9, the long shaft 4 drives the support block 3 to adjust the angle with the hanging block 8, so that the hanging block 8 can contact the outside of the force block 9, and the bottom clamp handle 1 forms a pulling force on the top clamp handle 1 through the hanging block 8 and the spring 6, so that the two clamp heads 2 can continuously apply clamping force to the cable.
