Description

Technical Field

[0001] This utility model relates to the field of power construction tools, specifically a power construction clamp. Background Technology

[0002] Electrical construction pliers are commonly used professional hand tools in power engineering construction, primarily used for cable cutting, conductor stripping, and terminal crimping in power line installation and maintenance operations. Their core features include insulated handles (usually made of high-voltage resistant rubber or composite materials) and pliers heads crafted from special steel, capable of withstanding voltage environments above 10kV to ensure operator safety. Common types include cable cutters (for cutting thick cables), crimping pliers (with modular molds for crimping different sized terminals), wire strippers (for precisely stripping conductor insulation without damaging the conductor), and multi-functional combination pliers. In substation construction and overhead line erection scenarios, electrical construction pliers can efficiently complete critical processes such as conductor forming and connection fixing.

[0003] Traditional wire strippers make it difficult for operators to accurately control the cutting depth during wire stripping operations. This can lead to incomplete or excessive stripping of the insulation layer and may also cause mechanical damage to the internal conductor. Such damage directly affects the conductivity and mechanical strength of the conductor, thereby threatening the safe and stable operation of the entire circuit system. In addition, the insulation sleeve of traditional wire strippers is usually connected to the handle in a fixed manner. This structural design makes it extremely inconvenient to replace the insulation sleeve when it becomes worn, aged, or damaged during long-term use, reducing the safety and convenience of using the wire strippers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrical construction clamp to solve the problems mentioned in the background art, such as the difficulty in controlling the cutting depth of traditional construction clamps leading to cable damage, and the difficulty in replacing the fixed connection of the insulation sleeve affecting safety.

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a pair of electrical construction pliers, including a handle 1, a plier head 2 at the top of the handle 1, an insulating sleeve 17 at the end of the handle 1, a wire stripping opening 3 and a groove 4 on the opposite side of the plier head 2, an inner groove 5 on the inner wall of the wire stripping opening 3, a blade holder 6 inside the inner groove 5, a blade 7 inside the blade holder 6, a connector 8 fixedly connected to the side of the blade holder 6 away from the blade 7, a threaded rod 9 rotatably connected inside the connector 8, a fixing rod 11 fixedly connected to the upper surface of the blade holder 6, a pointer 12 fixedly connected to the top of the fixing rod 11, a scale line 13 on the upper surface of the plier head 2, and a fixing block 15 fixedly connected to the lower surface of the blade holder 6.

[0022] Specifically, the outer surface of the threaded rod 9 is threaded into the inside of the pliers head 2. The end of the threaded rod 9 away from the connector 8 passes through the pliers head 2. The end of the threaded rod 9 away from the connector 8 is fixedly connected to a rotating block 10. By rotating the rotating block 10, the threaded rod 9 is rotated, thereby achieving precise adjustment of the blade spacing 7, which facilitates accurate control of the wire stripping depth.

[0023] Specifically, the top of the inner groove 5 is provided with a first guide groove 14, the outer surface of the fixing rod 11 passes through the first guide groove 14, the bottom of the inner groove 5 is provided with a second guide groove 16, and the outer surface of the fixing block 15 is slidably disposed inside the second guide groove 16. The first guide groove 14 and the second guide groove 16 respectively provide sliding tracks for the fixing rod 11 and the fixing block 15, ensuring that the tool holder 6 remains stable and does not deviate when moving.

[0024] Specifically, a connecting plate 19 is fixedly connected to the outer surface of the pliers handle 1, and a plug rod 20 is sleeved inside the connecting plate 19. A pull block 22 is fixedly connected to the end of the plug rod 20, and a spring 21 is sleeved on the outer surface of the plug rod 20. By pulling the pull block 22, the plug rod 20 can be pulled out from the through hole of the pliers handle 1 and the insulating sleeve 17, thereby unlocking the insulating sleeve 17 for easy replacement and maintenance.

[0025] Specifically, the end of the spring 21 is fixedly connected to the connecting plate 19, and the end of the spring 21 away from the connecting plate 19 is fixedly connected to the pull block 22. The spring 21 provides elastic force to ensure that the insertion rod 20 can automatically reset when there is no external force.

[0026] Specifically, the outer surface of the insulating sleeve 17 is provided with a first through hole 18, the outer surface of the pliers handle 1 is provided with a second through hole 23, and the outer surface of the insertion rod 20 is adapted to the interior of the first through hole 18 and the second through hole 23. The design of the first through hole 18 and the second through hole 23 allows the insertion rod 20 to pass through, thereby fixing the insulating sleeve 17 to the pliers handle 1.

[0027] The working principle of the above embodiments:

[0028] During wire stripping, the rotating block 10 drives the threaded rod 9 to rotate and move. Since the end of the threaded rod 9 is rotatably connected to the connector 8, and the second guide groove 16 provides a sliding constraint on the fixing block 15 at the bottom of the cutter holder 6, the cutter holder 6 moves axially along the threaded rod 9 under its push. The pointer 12 moves synchronously with the cutter holder 6 under the connection of the fixing rod 11. The pointer 12 controls the precise movement of the cutter holder 6 according to the scale indicated by the pointer 12, precisely adjusting the spacing of the blades 7 to control the cutting depth. The closer the blades 7 are, the deeper the cut; the farther apart the blades 7 are, the shallower the cut. After setting the depth, the pliers are used normally for wire stripping. The cable is placed between the two blades 7 inside the stripping opening 3, and the pliers handle 1 is controlled... The clamp heads 2 are closed together, and the two blades 7 stop when they close to the set gap, precisely cutting the cable insulation layer to the set depth. The insulating sleeve 17 is located in the hand-held part of the clamp handle 1. When the insulating sleeve 17 is damaged, pull the pull block 22 to move the insertion rod 20 away from the second through hole 23 and the first through hole 18, so that the insulating sleeve 17 can be removed from the clamp handle 1 and replaced with a new insulating sleeve 17. Put the new insulating sleeve 17 on the tail end of the clamp handle 1, pull the pull block 22, and align the first through hole 18 on the insulating sleeve 17 with the second through hole 23 on the clamp handle 1. Release the pull block 22, and under the elastic force of the spring 21, the insertion rod 20 is inserted into the first through hole 18 and the second through hole 23, so that the insulating sleeve 17 is fixed on the clamp handle 1.
