When the bent wire 3 passes through the inner wall of the insertion groove 10, the wire 3 is straightened to ensure that the wire 3 is effectively straightened in the process of passing through the insertion groove 10, the top of the support plate 11 is respectively rotatably connected to the first V-shaped groove wheel 7 and the second V-groove wheel 8 for assisting the wire 3 threading through the bearing, and a clamping assembly 2 is provided at one end of the wire 3;

[0029] A motor 5 is fixed to one side of the top of the fixed plate 1, and the output shaft end of the motor 5 is fixed to one end of the input shaft of the second V-groove wheel 8. Under the power of the motor 5, the wire 3 can be pushed for threading without manual pulling. The outer side of the wire 3 is wrapped around the middle outer side of the first V-groove wheel 7 and the second V-groove wheel 8, and the outer side of the wire 3 slides through one side of the insertion groove 10, and the outer side of the wire 3 is inserted into the inner side of the limit groove 23.

[0030] In order to facilitate the release or connection of the wire 3 and the connecting tube 21, a clamping assembly 2 is provided, which includes a connecting tube 21, a limiting groove 23 is provided on one side of the connecting tube 21, and a first slide groove 26, a second slide groove 29 and a third slide groove 212 are provided inside the connecting tube 21. A screwdriver is used to contact one side of the push plate 27, so that the push plate 27 slides inside the first slide groove 26, and then the push rod 25 drives the slide plate 210 to slide inside the third slide groove 212. A plurality of ball sockets are provided on the surface of the connecting tube 21, and a rotating ball 22 is connected to the inner ball of the ball socket. When the connecting tube 21 is in the wire tube, When the part moves, the rotating ball 22 in contact with the wire tube rotates in the ball socket to reduce the friction between the connecting tube 21 and the wire tube. The slider 24 is slidably connected to the inner side of the second slide groove 29. A guide slide groove 213 is provided on one side of the slider 24. Teeth that abut against the outer side of the wire 3 are fixed at the bottom of the slider 24. Teeth that clamp the wire 3 are provided at the bottom of the slider 24 to ensure that the wire 3 will not be damaged or accidentally clamped during the fixing or releasing process, so that the push rod 25 slides on the inner side of the guide slide groove 213. Since the guide slide groove 213 is inclined, the slider 24 slides upward on the inner side of the second slide groove 29.

[0031] The third slide groove 212 is slidably connected to the slide plate 210, and a second spring 211 is connected between one side of the slide plate 210 and the inner side of the third slide groove 212. The slide block 24 compresses the first spring 28. At this time, the multiple teeth at the bottom of the slide block 24 leave the outer side of the wire 3. At this time, the connecting tube 21 on one side of the wire 3 can be easily removed. The first slide groove 26 is slidably connected to the inner side of the first slide groove 26. A push plate 27 is fixed on one side of the push plate 27 to slide and connect to one side of the guide slide groove 213. One side of the slide plate 210 is fixed to one side of the push rod 25. The wire 3 continues to be connected to the connecting tube 21, and the next wire 3 can be assisted in threading. The wire 3 can be released or connected to the connecting tube 21 by simply touching the push plate 27 with a screwdriver. No complicated operation steps or tools are required, which greatly saves time. The first spring 28 is connected between the inner wall of the second slide groove 29 and one side of the slide block 24. Universal wheels 4 are installed around the bottom of the fixed plate 1.

[0032] Working principle: When the electrician needs to thread the wire 3 into the wire tube, the rolled wire 3 is placed on the top of the turntable 6, and then the wire 3 is inserted between the first V-groove wheel 7 and the second V-groove wheel 8, and then the wire 3 is inserted into the inner side of the insertion groove 10, and one end of the wire 3 is inserted into the inner side of the limit groove 23, the connecting tube 21 is connected to the wire 3 and inserted into the wire tube, and then the switch is pressed to start the motor 5, and the output shaft of the motor 5 drives the second V-groove wheel 8 to rotate, and the outer sides of the first V-groove wheel 7 and the second V-groove wheel 8 are respectively squeezed on the outer side of the wire 3, and the wire 3 can be transported at this time, and the wire 3 is transported to the inner side of the insertion groove 10. Since the inner side of the insertion groove 10 has a certain length, the bent wire 3 can be straightened when passing through the inner wall of the insertion groove 10, ensuring that the wire 3 is effectively straightened in the process of passing through the insertion groove 10, avoiding the damage of the wire 3 due to bending during the threading process, and ensuring the quality of the wire 3.

[0033] When the wire 3 passes through the wire tube under the action of the connecting tube 21, it is only necessary to use a screwdriver to contact one side of the push plate 27, so that the push plate 27 slides inside the first slide groove 26, and then the push rod 25 drives the slide plate 210 to slide inside the third slide groove 212, and at the same time, the push rod 25 slides inside the guide slide groove 213. Since the guide slide groove 213 is inclined, the slider 24 slides upward inside the second slide groove 29, so that the slider 24 compresses the first spring 28, and at this time, the bottom multiple teeth of the slider 24 leave the outside of the wire 3, which is very convenient. Remove the connecting cylinder 21 on one side of the wire 3, and continue to connect the wire 3 to the connecting cylinder 21 in this way to assist in threading the next wire 3. Use a screwdriver to simply push against the push plate 27 to release or connect the wire 3 and the connecting cylinder 21. No complicated operating steps or tools are required, which greatly saves time and improves work efficiency. Teeth that clamp the wire 3 are provided at the bottom of the slider 24 to ensure that the wire 3 will not be damaged or accidentally clamped during the fixing or releasing process. At the same time, the compressed first spring 28 ensures that the slider 24 can be quickly reset when needed, thereby improving the safety of operation.
