[0030] This utility model embodiment provides a cable sample cutting device 100, such as... Figures 1 to 3 As shown, the cable sample cutting device 100 includes a base 1, a fixed base 2, an adjustment mechanism 3, and a cutting blade 4.

[0031] The base 1 has a cutting position 11, and the fixing seat 2 has multiple fixing cavities 21 for fixing cables, with at least two fixing cavities 21 having different radial lengths. The fixing seat 2 is movably disposed on the base 1, and applying an external force to the fixing seat 2 can move the fixing seat 2 relative to the base 1, causing any one of the fixing cavities 21 to be located at the cutting position 11. Specifically, each fixing cavity 21 of the fixing seat 2 can fix one cable. By forming at least two fixing cavities 21 with different radial lengths on the fixing seat 2, cables of different specifications can be assembled into fixing cavities 21 of appropriate size on the fixing seat 2, thereby fixing cables of different specifications. Since the fixing seat 2 is movably disposed on the base 1, an external force can be applied to the fixing seat 2 according to the specific position of the fixing cavity 21 where the cable is assembled, causing the fixing cavity 21 with the cable to be moved to the cutting position 11 for cutting.

[0032] The cutting knife 4 is movably arranged on the base 1, the adjusting mechanism 3 is connected with the cutting knife 4 and drives the cutting knife 4 to move to adjust the depth of the cutting knife 4 extending into the cutting position 11.

The front-rear direction and the left-right direction of the base 1 are defined according to the position of the user, and the end facing the user is the front end. The two first positioning holes 12 are arranged on the opposite sides of the front end of the base 1 in the cable cutting direction. The fixing seat 2 is provided with a second positioning hole 24 on the opposite sides of each fixing cavity 21 in the cable cutting direction. The distance between the two first positioning holes 12 is the same as the distance between the two adjacent second positioning holes 24. When any fixing cavity 21 of the fixing seat 2 moves to the cutting position 11, the base 1 is connected to the fixing seat 2 by being sequentially arranged in the first positioning hole 12 and the second positioning hole 24 through fasteners.

When any fixing cavity 21 of the fixing seat 2 moves to the cutting area of the cutting position 11, the second positioning hole 24 on the left and right sides of the fixing cavity 21 corresponds to the two first positioning holes 12 on the base 1. At this time, the base 1 can be sequentially arranged in the first positioning hole 12 and the second positioning hole 24 through fasteners such as screws or positioning pins to connect the fixing seat 2.

In addition, it should be noted that in other embodiments, elastic positioning pins can be arranged on the opposite sides of each fixing cavity 21 of the fixing seat 2 in the cable cutting direction, and the base 1 is provided with a clamping groove. When the fixing seat 2 is moved to the position, the elastic positioning pins are elastically clamped into the clamping groove to form a position indication, and the fixing seat 2 can be better fixed on the base 1.
