Technical Field
[0001] This utility model relates to the field of cable cutters, specifically a ratchet cable cutter. Background Technology
[0002] In modern power, communications, and various industrial sectors, cables serve as a crucial carrier for power and signal transmission, finding widespread application in diverse scenarios. From underground cable laying in urban power grids to towering communication base station signal cable connections, from complex power cable wiring in factory workshops to specialized cable assembly in high-precision fields such as aerospace, cables are ubiquitous. With the rapid development of the industry, cable specifications and materials are becoming increasingly diverse, placing higher demands on the performance of cable cutting tools. In the field of mechanical transmission, ratchet mechanisms, as a classic unidirectional intermittent motion mechanism, have long been widely used. Composed of a gear-like ratchet and pawl, they can continuously... The continuous rotation or reciprocating motion is cleverly converted into unidirectional stepping motion. In the flywheel mechanism of a bicycle, when the rider steps on the pedal, the chain drives the sprocket to rotate, and the sprocket drives the wheel forward through the ratchet mechanism. When the rider stops stepping on the pedal, the ratchet mechanism locks to prevent the wheel from rotating backward, ensuring riding safety and smoothness. In tools such as hand wrenches and jacks, the ratchet mechanism also plays a key role. Through multiple small-amplitude reciprocating operations, it achieves high torque output to complete tasks such as bolt tightening and lifting heavy objects. Inspired by this, the ratchet mechanism is introduced into the design of cable cutters, which is an innovative idea to solve the problem of labor saving and high efficiency of traditional cable cutters. Therefore, a ratchet cable cutter is needed.
[0003] Existing ratchet cable cutters lack a dedicated positioning structure in the jaws and blade area, relying solely on the operator's visual estimation or experience to determine the cutting point. This easily leads to positioning errors when dealing with cables of different specifications and laying scenarios. Furthermore, the handle is a fixed, one-piece structure with no adjustable length, making it impossible to adapt to different diameters and hardnesses by extending the handle arm to save effort. This results in a significant physical burden on the operator. Therefore, a ratchet cable cutter is urgently needed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a ratchet cable cutter to solve the problems of existing ratchet cable cutters, which lack a dedicated positioning structure for the cutting position in the jaw and blade areas. The cutting point relies solely on the operator's visual estimation or experience, which easily leads to positioning errors when dealing with cables of different specifications and laying scenarios. Furthermore, the handle is a fixed, one-piece structure with no adjustable length, making it impossible to adapt to the need for effort reduction by extending the handle arm when dealing with cables of different diameters and hardness, thus requiring the operator to bear a significant physical burden.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a ratchet cable cutter, including a mounting base, wherein a first magnetic frame is adhered to the inner wall of the mounting base, a second magnetic frame is attached to the outer wall of the first magnetic frame, and a laser light is adhered to the outer wall of the second magnetic frame.
[0006] A rotating rod is installed at one end of the mounting base. A ratchet blade is installed on the outer wall of the rotating rod. A ratchet block is installed on the outer wall of the ratchet blade. A first spring abuts against one side of the ratchet block. A pressing rod is installed on the outer wall of the ratchet block. A second spring is welded to the outer wall of the mounting base. An anti-reverse block is welded to one end of the second spring. A first fixing rod is fixedly connected to the inner wall of the mounting base. A connecting rod is fixedly connected to the outer wall of the first fixing rod. A second fixing rod is fixedly connected to the inner wall of the mounting base. A fixing cover is fixedly connected to the outer wall of the second fixing rod. A fixing sleeve abuts against the outer wall of each connecting rod. An adjusting rod is fixedly connected to the inner wall of the fixing sleeve. A first extension handle is welded to the outer wall of the adjusting rod. A second extension handle is installed on the outer wall of the pressing rod.
[0007] Preferably, the inner wall of the mounting base is in close contact with the outer wall of the first magnetic frame, and the width of the inner wall of the mounting base is greater than the width of the outer wall of the first magnetic frame.
[0008] Preferably, the outer wall of the second magnetic frame is in close contact with the outer wall of the laser lamp, and the width of the outer wall of the second magnetic frame is the same as the width of the outer wall of the laser lamp.
[0009] Preferably, the connecting rod is movably connected to the first extended grip, and one end of the connecting rod has an open design.
[0010] Preferably, the fixing sleeve is threadedly connected to the adjusting rod, and the fixing sleeve is symmetrically arranged about the central axis of the connecting rod.
[0011] Preferably, the second extended grip is movably connected to the pressing rod, and the inner wall of the second extended grip has a slotted design.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets the first magnetic frame as a ring structure, using neodymium iron boron strong magnetic material, and uses epoxy resin to bond and fix it to the mounting base, ensuring that there is no relative displacement between the first magnetic frame and the mounting base. The second magnetic frame is a ring structure that matches the first magnetic frame, also using neodymium iron boron strong magnetic material, and uses epoxy resin to bond and fix it to the laser lamp. When the second magnetic frame of the assembled laser lamp is aligned with the first magnetic frame, the magnetic attraction force makes the two stick together and adhere, ensuring that the axis of the laser lamp is aligned with the cutting center. The laser lamp spot will continuously project on the cutting position of the cable, assisting in positioning the position to be cut. 2. This utility model features a pressing rod and a connecting rod made of 45# steel, and a first and second extended grip made of a composite of ABS engineering plastic and TPR anti-slip material. After the first and second extended grips are extended to the target length, the two fixing sleeves are screwed and rotated to position the first and second extended grips against each other, preventing axial displacement during the shearing process. Due to the extended length of the first and second extended grips, the operating lever arm is amplified. According to the lever principle, the operating force is greatly reduced, allowing even weak operators to easily complete the shearing. Attached Figure Description

[0017] Please see Figure 1-6A ratchet cable cutter includes a mounting base 1. A first magnetic frame 2 is adhered to the inner wall of the mounting base 1, and the inner wall of the mounting base 1 is in close contact with the outer wall of the first magnetic frame 2. The width of the inner wall of the mounting base 1 is greater than the width of the outer wall of the first magnetic frame 2. A second magnetic frame 3 is adhered to the outer wall of the first magnetic frame 2, and a laser lamp 4 is adhered to the outer wall of the second magnetic frame 3. The outer wall of the second magnetic frame 3 is in close contact with the outer wall of the laser lamp 4, and the width of the outer wall of the second magnetic frame 3 is the same as the width of the outer wall of the laser lamp 4. By setting the first magnetic frame 2 as a ring structure and using neodymium iron boron... The first magnetic frame 2 is made of magnetic material and is bonded to the mounting base 1 with epoxy resin to ensure that there is no relative displacement between the first magnetic frame 2 and the mounting base 1. The second magnetic frame 3 is a ring structure that matches the first magnetic frame 2. It also uses neodymium iron boron strong magnetic material and is bonded to the laser lamp 4 with epoxy resin. The second magnetic frame 3 of the assembled laser lamp 4 is aligned with the first magnetic frame 2. The magnetic attraction force makes the two stick together and ensure that the axis of the laser lamp 4 is aligned with the cutting center. The light spot of the laser lamp 4 will be continuously projected on the cutting position of the cable to assist in positioning the position that needs to be cut.
[0018] Please see Figure 1-6 A ratchet cable cutter includes a mounting base 1 with a rotating rod 5 at one end, a ratchet blade 6 on the outer wall of the rotating rod 5, a ratchet block 7 on the outer wall of the ratchet blade 6, a first spring 8 abutting one side of the ratchet block 7, a pressing rod 9 on the outer wall of the ratchet block 7, a second spring 10 welded to the outer wall of the mounting base 1, an anti-reverse block 11 welded to one end of the second spring 10, a first fixing rod 12 fixedly connected to the inner wall of the mounting base 1, a connecting rod 13 fixedly connected to the outer wall of the first fixing rod 12, a second fixing rod 14 fixedly connected to the inner wall of the mounting base 1, a fixing cover 15 fixedly connected to the outer wall of the second fixing rod 14, a fixing sleeve 16 abutting the outer wall of the connecting rod 13, an adjusting rod 17 fixedly connected to the inner wall of the fixing sleeve 16, the fixing sleeve 16 and the adjusting rod 17 being threadedly connected, and the fixing sleeve 16 being symmetrically arranged about the central axis of the connecting rod 13, and a first extension handle 18 welded to the outer wall of the adjusting rod 17. The connecting rod 13 is movably connected to the first extended grip 18, and one end of the connecting rod 13 has an open design. The outer wall of the pressing rod 9 is equipped with a second extended grip 19, which is movably connected to the pressing rod 9. The inner wall of the second extended grip 19 has a slotted design. The pressing rod 9 and the connecting rod 13 are made of 45# steel, while the first extended grip 18 and the second extended grip 19 are made of a composite of ABS engineering plastic and TPR anti-slip material. After the first extended grip 18 and the second extended grip 19 are extended to the target length, the two fixing sleeves 16 are screwed and rotated to make the first extended grip 18 and the second extended grip 19 collide and position themselves, preventing axial displacement during the shearing process.

Attach and fix the mounting base 1 to the first magnetic frame 2, then attach and fix the second magnetic frame 3 to the laser lamp 4. Next, magnetically fix the mounting base 1 to the laser lamp 4. According to usage requirements, extend the pressing rod 9 to the second extension handle 19 to the designated position, then extend the connecting rod 13 to the first extension handle 18 to the designated position. Then, rotate the adjusting rod 17 through the threaded screw of the fixing sleeve 16, causing the fixing sleeve 16 to contact and fix the first extension handle 18 and the second extension handle 19. Finally, turn on the laser lamp 4, insert the cable into the mounting base 1 and the ratchet blade 6, position the laser lamp 4 spot at the desired cutting location, press the second extension handle 19, causing the second extension handle 19 to drive the ratchet block 7 to contact, rotating the ratchet blade 6 to cut the cable. This completes the device's usage process. Content not described in detail in this manual is prior art known to those skilled in the art.
