[0035] When the device is used, the pressing plate 104 is pressed. At this time, the extrusion rod 108 squeezes the extrusion rod 210 so that the extrusion rod 210 enters the sliding groove 3 206. Under the extrusion of the reset spring 204, the sliding block 202 slides in the sliding groove 201 through the sliding rod 1 203. When the sliding block 202 slides to the extrusion hole 2 14, the extrusion rod 210 enters the extrusion hole 2 14 under the action of the reset spring 3 208 to achieve the purpose of ejecting the fixing component 5.

[0036] See also Figure 6 The fixing assembly includes a fixing plate 301 , a wire insertion hole 303 is opened on the surface of the fixing plate 301 , and both ends of the fixing plate 301 are rotatably connected with a rotating block 302 , and one end of the rotating block 302 away from the fixing plate 301 is rotatably connected to the rotating rod 205 .

[0039] Working principle: When using the device, first press the leftmost and rightmost pressing plates 104 at the same time to drive the extrusion rod 108 to move inside the extrusion hole 13, thereby extruding the extrusion rod 210 to move inside the square groove 211. When the extrusion rod 210 enters the sliding groove 3 206, the sliding block 202 slides inside the sliding groove 201 through the sliding rod 1 203 under the pressure of the return spring 204. When the sliding block 202 slides to the extrusion hole 2 14, the extrusion rod 210 enters the extrusion hole 2 14 under the action of the return spring 3 208. The sliding block 202 drives the rotating rod 205 to move, and then drives the rotating block 302 to move, and then the fixed plate 301 is ejected from the inside of the wiring groove 9. When use is over, the two inner pressing plates 104 are pressed at the same time to squeeze the extrusion rod 210 into the sliding groove 3 206, and the fixed plate 301 is pressed downward to make the extrusion rod 210 enter the extrusion hole 13, and then the closing plate 8 is buckled out from the inside of the storage groove 6, and the rotating column 401 is rotated.
