[0020] See also Figure 1 , Figure 2 and Figure 3 The front handle assembly 1 includes a front handle 12, one end of which is fixedly installed with a metal pin receiving groove 13, one end of which is fixedly installed with an annular knife fixing cover plate 14 by a first fastening screw 17, and the other end of the metal pin receiving groove 13 is fixedly connected to the front handle 12 by a second fastening screw 18, and a hollow cone head propulsion rod 4 is installed through the metal pin receiving groove 13, and the hollow cone head propulsion rod 4 is an axial circular center-penetrating hollow rod, one end of which is conically arranged, the middle is an annular boss structure, and the other end is provided with an external thread structure, and the hollow cone head propulsion rod 4 is located at one end outside the metal pin receiving groove 13 and is fixedly installed with a spring 5, and one end of the metal pin receiving groove 13 is fixedly installed with an annular knife fixing base 1 5. A guide groove 19 is fixedly installed at the other end of the metal pin receiving groove 13. The surface of the part between the boss of the hollow cone head propulsion rod 4 and the end thread structure is smooth and matched with a small gap in the guide groove 19, and can slide freely in the guide groove 19; an annular knife 20 is fixedly installed in the annular knife fixed base 15. The surface of the annular knife 20 is cylindrical, and the inner surface is funnel-shaped. An annular cutting edge is formed at the intersection of the funnel mouth end of the annular knife 20 and the bottom surface of the cylinder, and the cutting edge is sharp and has strong hardness; the outer diameter of the top of the conical head of the hollow cone head propulsion rod 4 is smaller than the inner diameter of the cutting edge of the annular knife 20, and the outer diameter of the end of the conical head of the hollow cone head propulsion rod 4 is larger than the inner diameter of the cutting edge of the annular knife 20. A receiving groove cover plate 16 is fixedly installed on one side of the metal pin receiving groove 13;

[0021] See also Figure 1 and Figure 2The rear handle assembly 2 includes a rear handle 11, one end of which is fixedly installed with a fixing pin 6, the threaded connecting rod 3 passes through the fixing pin 6 and is fixedly installed at one end of the metal pin receiving groove 13, both ends of the fixing pin 6 are fixedly installed with spring baffles 7, one end of the rear handle 11 is symmetrically installed with a linkage block 9 below the fixing pin 6, one end of the hollow cone head propulsion rod 4 is fixedly installed with a propulsion rod base 8, and the linkage block 9 is pin-connected with the propulsion rod base 8 by a pin 10.

[0022] Working principle: insert the shielded wire to be cut from the inner circle of the annular knife 20, the core wire of the shielded wire moves along the middle hole of the hollow cone head push rod 4, and the shielding net moves along the outer side of the hollow cone head push rod 4. When the shielded wire is sent to the appropriate position, hold the front handle 12 and the rear handle 11 with one hand. During the process of closing the two, the rear handle 11 rotates along the fixed pin 6, the linkage block 9 drives the push rod base 8 to move forward, and the spring 5 is compressed. Under the action of the guide groove 19, the hollow cone head push rod 4 moves along the direction of the guide groove 19, and the end of the hollow cone head push rod 4 gradually approaches the blade of the annular knife 20, and finally the blade of the annular knife 20 and the conical slope of the end of the hollow cone head push rod 4 are closed. Thus, the shielding net on the surface of the shielded wire sandwiched between them is cut once, the shielded wire is pulled out, the front handle 12 and the rear handle 11 are loosened, and the cut shielding net is left in the cavity of the metal pin storage groove 13, completing the operation cycle. By replacing the hollow cone head push rod 4 and the annular knife 20, various wire cutting can be met.
