[0023] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1 is given by Figure 1-2 The present utility model includes a housing 1, a pressing mechanism 2 is installed on the housing 1, and a reset mechanism 3 is installed on the pressing mechanism 2.

[0025] Specifically, it is given by Figure 3-4 The pressing mechanism 2 includes an inner shaft 201 rotatably connected to the inside of the housing 1. A V-shaped plate 202 is fixedly sleeved on the outside of the inner shaft 201. A rubber column 203 is fixedly installed at the bottom end of the V-shaped plate 202. An inner plate 208 is fixedly installed inside the housing 1. A side frame 209 is fixedly installed on one side of the inner plate 208 close to the V-shaped plate 202. A movable column 2011 is movably sleeved inside the side frame 209. A contact ball 2010 is fixedly installed at one end of the movable column 2011 away from the inner plate 208. A limiting groove 2012 is provided at the top of the side frame 209. A limiting block 2013 is slidably connected inside the limiting groove 2012. The limiting block 2013 is fixed to the outside of the movable column 2011. A through groove 4 is provided at the top of the housing 1. A screw 205 is rotatably connected inside the through groove 4. One end of the screw 205 extends to the outside of the housing 1 and is fixedly installed with a turntable 204. A nut 206 is threadedly sleeved on the outside of the screw 205 and is located directly above the limiting block 2013. A connecting column 207 is fixedly connected between the nut 206 and the limiting block 2013. The V-shaped plate 202 is composed of an upper arm and a lower arm. The upper arm and the lower arm form a lever structure. The rubber column 203 is fixed on the lower arm, and the contact ball 2010 moves and directly abuts against the upper arm, which is convenient for the V-shaped plate 202 to rotate;

[0026] In the use state, first rotate the turntable 204 to drive the screw 205 to rotate, and drive the nut 206 to slide inside the through groove 4, and then drive the limiting block 2013 to slide inside the limiting groove 2012 through the connecting column 207. At the same time, the movable column 2011 moves horizontally. Since the inner shaft 201 is rotatably connected to the inside of the housing 1, and at the same time the V-shaped plate 202 is fixedly sleeved on the outside of the inner shaft 201, the movable column 2011 drives the contact ball 2010 to move and push the V-shaped plate 202 to rotate until the rubber column 203 squeezes the wire, and finally the wire is quickly fastened.

[0027] Specifically, it is given by Figure 5As shown, the reset mechanism 3 includes an L-shaped round rod 301 fixed to one side of the inner plate 208 close to the side frame 209. One end of the L-shaped round rod 301 away from the inner plate 208 is fixedly connected to the housing 1. The L-shaped round rod 301 is located above the inner shaft 201. A sliding plate 302 is movably sleeved on the outer side of the L-shaped round rod 301. A toothed plate 305 is fixedly installed at the bottom of the sliding plate 302. A gear 304 is fixedly installed on the outer side of the inner shaft 201. The gear 304 is meshed with the toothed plate 305. A spring 303 is fixedly connected between the sliding plate 302 and the inner plate 208. The spring 303 is sleeved on the outer side of the L-shaped round rod 301;

[0028] In the use state, when the abutting ball 2010 pushes the V-shaped plate 202 to rotate it, it drives the inner shaft 201 to rotate and drives the gear 304 to rotate. Since the gear 304 is meshed with the toothed plate 305, it drives the sliding plate 302 to slide along the L-shaped round rod 301 and away from the inner plate 208. At this time, the spring 303 is stretched. When the abutting ball 2010 is separated from the V-shaped plate 202, the spring 303 is reset at this time, driving the sliding plate 302 to slide along the L-shaped round rod 301 and close to the inner plate 208, and driving the V-shaped plate 202 to rotate in the reverse direction to separate the rubber column 203 from the wire, and finally releasing the fixation of the wire to facilitate separation from the housing 1.
