[0026] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] The utility model discloses a cable clamp to solve the prior art problems, in the utility model, the cutting tooth is arranged on the arc-shaped shearing blade, the tooth tip of the cutting tooth is pierced into the outermost sheath to be fixed when shearing the cable, and the tooth tip can prevent the arc-shaped shearing blade from sliding along the cable when cutting, guaranteeing the accurate cutting position.

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0029] As Figure 1 and Figure 3 shown, the utility model provides a cable clamp, including two articulated cable clamp monomers, the cable clamp monomer includes handle 1 and shearing part 2, the first end of the handle 1 is connected to the connecting end of the shearing part 2, the shearing part 2 is provided with arc-shaped shearing blade, and the cutting tooth 3 for preventing the shearing part 2 from sliding is arranged on the shearing blade, the cutting tooth 3 includes tooth tip 301 and tooth arc 302, the tooth arc 302 is bent inward to the shearing part 2, the tooth arc 302 is sequentially arranged, and the adjacent tooth arcs 302 intersect to form tooth tip 301. When shearing the cable, the two opposite shearing blades are closed, and the tooth tip 301 will be pierced into the outermost sheath of the cable to complete the fixation during the closing process, so that the shearing part 2 will not slide along the cable.

[0030] As Figure 2 and Figure 4 shown, in an embodiment, the number of tooth arcs 302 is 3. It can be understood that the number of tooth arcs 302 can also be other numbers that can meet the shearing needs.

[0031] As Figures 1 to 4As shown, the contact surfaces of the two shearing parts 2 are flat, and the cutting edge of the shearing blade gradually thickens from the top to the root. The top of the cutting edge is the side where the shearing blade contacts the cable, and the root of the cutting edge is the connection point between the shearing blade and the shearing part 2. The flat contact surfaces of the two shearing parts 2 ensure that they fit completely together when closed, and the gradual thickening of the cutting edge from the top to the root prevents cable debris from getting trapped between the two shearing blades during cutting, ensuring a smooth cable cut.

[0032] In one embodiment, the cutting edge angle is 10 degrees to 75 degrees. The cutting edge angle is the angle between the line connecting the top and root of the shearing blade when the shearing part 2 is placed horizontally and the horizontal plane. The smaller the cutting edge angle, the sharper the shearing blade.

[0033] like Figure 2 and Figure 4 As shown, the toothed arc 302 is a circular arc shape. When the sheath is pierced by the tooth tip 301, the damaged part of the sheath will be squeezed into the toothed arc 302. The circular arc design allows the toothed arc 302 to better match the natural deformation shape of the sheath. Compared with other shapes, the circular arc shape has a longer contact length with the sheath, resulting in better fixation. It can be understood that the toothed arc 302 could also be any other shape that can accommodate the damaged part of the sheath.

[0034] In one embodiment, the diameter of the tooth arc 302 is 5 mm to 25 mm.

[0035] like Figure 2 and Figure 4 As shown, the tip of tooth 301 has a pointed shape. Compared to other shapes, a pointed tip has stronger piercing power and is more likely to pierce the sheath to achieve fixation. It is understandable that tooth tip 301 could also be any other shape capable of piercing the sheath.

[0036] In one embodiment, the included angle at the top of the tooth tip 301 is 10 degrees to 90 degrees.

[0037] like Figure 2 As shown, the top of the tooth tip 301 is located on the trajectory of the shearing blade. The cutting tooth 3 is built into the shearing blade. When the shearing blade closes, the tooth tip 301 contacts the cable, and other parts of the shearing blade also contact the cable. Fixing and shearing are performed simultaneously, which can improve the shearing efficiency and is suitable for cables with smaller diameters.

[0038] like Figure 4 As shown, the bottom of the tooth arc 302 is tangent to the trajectory of the shearing blade. The cutting tooth 3 is placed outside the shearing blade. When the shearing blade closes, the tooth tip 301 contacts the cable first. After the cutting tooth 3 is fully inserted into the cable sheath, it is cut off. The entire shearing process is divided into two steps. The fixing effect of the cutting tooth 3 being fully inserted into the sheath is better. Even if the shearing force is large, it will not cause the shearing part 2 to slip. It is suitable for cables with large diameters that require heavy shearing.

[0039] In an embodiment, the handle 1 is provided with an insulating anti-slip portion.
