DETAILED DESCRIPTION
[0023] For the convenience of those skilled in the art to understand, the following further detailed description of the utility model is made in combination with the drawings and specific embodiments.
[0024] As shown in Figure 1 , 2 , a fixing device for cable cutting comprises a base 1, the base 1 is provided with a wire inlet pipe 100 for the cable to pass through, and the cable will be fixed in the wire inlet pipe 100 in the subsequent cable fixing work. Three through holes 102 are arranged on the pipe wall of the wire inlet pipe 100 in the axial direction, and a wire pressing part 120 for pressing the cable is arranged in the through hole 102, and the wire pressing part 120 can be pressed into the wire inlet pipe 100 in the subsequent cable fixing work, so as to press and fix the cable, and the cooperation of the three wire pressing parts 120 can effectively prevent the cable from moving, thereby achieving good fixing effect, so as to facilitate the operator to cut the cable. The contact surface of the wire pressing part 120 in contact with the cable is provided with anti-skid lines to avoid axial movement of the cable.
[0025] As shown in Figure 1 , 2 , an elastic reset structure 110 for resetting the wire pressing part 120 is arranged between the wire pressing part 120 and the wire inlet pipe 100. After the fixing work of the cable is completed, the elastic reset structure 110 drives the wire pressing part 120 to reset, so as to facilitate the entry of the cable in the next work. The elastic reset structure 110 comprises a guide column 111 arranged on the outer wall of the wire inlet pipe 100, guide columns 111 are arranged on both sides of both ends of the through hole 102, supporting lugs 125 are arranged on the wire pressing part 120 and slide on the guide columns 111, springs 112 are arranged between the supporting lugs 125 and the wire inlet pipe 100, and the springs 112 are sleeved on the guide columns 111. When the wire pressing part 120 is pressed into the wire inlet pipe 100, the supporting lugs 125 will press the springs 112, and when the wire pressing part 120 does not need to be pressed into the pipe, the springs 112 can push the wire pressing part 120 to reset. Multiple guide columns 111 can improve the stability of the wire pressing part 120 sliding in the through hole 102, and avoid the deflection of the wire pressing part 120, and meanwhile, multiple springs 112 can avoid the incomplete reset caused by the excessive length of the wire pressing part 120.
