[0002] Cable cutters are a type of pliers specifically designed for cutting cables. They have two interlocking blades that can be opened and closed. Cable cutters are large-scale scissors, designed using the lever principle and the inverse relationship between pressure and area. To enhance strength and ease of use, cable cutters have evolved from traditional manual cable cutters to ratchet cable cutters, and subsequently to hydraulic cable cutters, electro-hydraulic cable cutters, and fully electric cable cutters.

[0003] A Chinese patent discloses an adjustable-angle T-shaped shoe (authorization announcement number CN 211831263 U). This patented technology can solve the problem that when cutting cables in the field, the ratchet cable cutter can only be placed on the ground for operation. However, squatting on the ground for a long time to cut cables is not only extremely inconvenient, but also further increases the labor consumption of workers.

[0004] However, existing cable cutters require workers to rotate the moving rod for extended periods to perform the cutting, which can easily cause arm pain and low work efficiency. Furthermore, after prolonged use, the cutter surface tends to accumulate debris, resulting in poor performance. Summary of the Invention

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The invention is provided for illustrative and descriptive purposes only and is not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The invention was chosen and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the invention and design various inventions with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-4 This embodiment provides a gear-type cable installation shear, including a base 1 and a cable shear 2. A support column 11 is installed on the upper surface of the base 1, and the cable shear 2 is engaged with the upper surface of the support column 11 via a first clamp. A movable blade 12 is arranged on the front side of the cable shear 2, and the outer wall of the movable blade 12 has a ratchet structure. A movable rod 13 is rotatably mounted on the rear end of the cable shear 2 via a pin. A positioning rod 14 is arranged below the movable rod 13, and the movable rod 13 and the positioning rod 14 are connected by a first spring 15. A back support is arranged behind the support column 11, and an L-shaped platform is installed on the upper surface of the back support. An adjustment mechanism is installed on the front end of the L-shaped platform. The motor 16 has an adjusting cam 17 installed at its output end. During operation, the cable is placed on the cable cutter 2, the adjusting motor 16 starts, and drives the adjusting cam 17 to rotate. During the rotation of the adjusting cam 17, it repeatedly presses the moving rod 13, thereby causing the moving blade 12 to rotate and cut the cable. This eliminates the need for the operator to repeatedly rotate the moving rod 13, reducing labor intensity and allowing for longer operation. It also improves the cutting efficiency of the cable cutter 2. The first spring 15 resets the moving rod 13. The first clamp structure facilitates the disassembly and installation of the cable cutter 2.

[0021] The support column 11 has a fixing groove inside, and an adjusting cylinder 18 is installed at the bottom of the fixing groove. A disc is installed at the output end of the adjusting cylinder 18, and pressure plates 19 are symmetrically installed on the outer side wall of the disc. When working, the adjusting cylinder 18 is activated, which drives the pressure plates 19 to move down, thereby limiting and fixing the top of the cable cutter 2, further improving the stability of the cable cutter 2 during operation.

[0022] The outer side wall of the support column 11 has symmetrical perforations. The pressure plate 19 passes through the perforations and is connected to them by a sliding fit. During operation, the sliding fit is used to ensure the stability of the pressure plate 19 moving up and down.

[0023] A front panel is arranged in front of the support column 11. A connecting plate 21 is symmetrically installed on the upper surface of the front panel. A fixing hole 22 is opened on the outer end of the connecting plate 21. During operation, the cable is passed through the fixing hole 22 to avoid the cable shaking during the cutting process, which would result in uneven cutting and ensure the stability of the cable cutting.

[0024] A fixed fan 23 is arranged on the inner side of the connecting plate 21. The fixed fan 23 is installed on the upper end of the front panel. When the moving blade 12 is cutting the cable for a long time during operation, the surface is prone to sticking with debris, which affects the cutting effect. The fixed fan 23 is started to clean the surface of the moving blade 12 and at the same time, it can also play a role in cooling and protecting the moving blade 12.

[0025] A circular rod is installed on the upper end face of the back stage, and an annular cavity 24 is installed on the upper end face of the circular rod. A positioning rod 14 is arranged inside the annular cavity 24. During operation, the annular cavity 24 supports and fixes the positioning rod 14.

[0026] In actual operation, the cable is passed through the fixing hole 22 to prevent the cable from shaking during the cutting process, which would lead to uneven cutting and ensure the stability of the cable shear 2 during cutting. The adjusting motor 16 is started, which drives the adjusting cam 17 to rotate. During the rotation of the adjusting cam 17, the moving rod 13 is repeatedly pressed, which causes the moving blade 12 to rotate and cut the cable. There is no need for the operator to repeatedly rotate the moving rod 13, which reduces the labor intensity and allows for long-term operation, thus improving the cutting efficiency of the cable shear 2. The first spring 15 plays a reset role for the moving rod 13. The first clamp structure is adopted to facilitate the disassembly and installation of the cable shear 2.

[0027] Obviously, the described invention is only a part of this utility model, not all of it. Based on the inventions in this utility model, all other inventions obtained by those skilled in the art and related fields without inventive effort should fall within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the art.
