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 creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-5 shown, a wire inserting jaw facilitating multi-line grasping includes a mechanical swing arm 1. A jaw assembly 2 is installed on the mechanical swing arm 1. The jaw assembly 2 includes a mounting plate 27 installed on the mechanical swing arm 1. The lower side surface of the mounting plate 27 is rotatably connected to a first jaw module 23. A displacement assembly located on the mounting plate 27 is arranged on one side of the first jaw module 23. A second jaw module 24 is installed on the displacement assembly to drive the second jaw module 24 to displace towards the first jaw module 23;

[0025] A first moving jaw 234 is arranged at the lower end of the first jaw module 23. A second moving jaw 244 opposite to the first moving jaw 234 is arranged at the lower end of the second jaw module 24;

[0026] A first motor 28 connected to the first jaw module 23 is fixed on the mounting plate 27; ​​

[0027] The second movable jaw 244 is a double-headed jaw;

[0028] During use, the distance between the first jaw module 23 and the second jaw module 24 is adjusted according to the specifications of the U-shaped copper wire. After the adjustment is completed, the first motor 28 drives the first jaw module 23 to rotate to adjust the clamping angle of the first jaw module 23 so as to facilitate clamping one of the pins of the U-shaped copper wire. The displacement assembly drives the second jaw module 24 to slide to adjust the distance between the second jaw module 24 and the first jaw module 23. After the adjustment is completed, the first jaw module 23 and the second jaw module 24 drive the first movable jaw 234 and the second movable jaw 244 to clamp the U-shaped copper wire to achieve the purpose of clamping the two pins of the U-shaped copper wire. When the wire insertion is completed, the first jaw module 23 and the second jaw module 24 are used to control the first movable jaw 234 and the second movable jaw 244 to stop clamping the U-shaped copper wire, and then continue to clamp another U-shaped copper wire;

[0029] While clamping the U-shaped copper wire, the second jaw module 24 clamps the I-shaped copper wire on the side away from the first jaw module 23 through the second movable jaw 244 to achieve the purpose of synchronous clamping.

[0030] In this embodiment, the displacement assembly includes a second motor 21 fixed to the lower side of the mounting plate 27, a first slide rail 26 located on one side of the second motor 21, a lead screw 22 rotatably connected to the first slide rail 26, and a sliding sleeve 25 slidably connected to the first slide rail 26. The rotating shaft of the second motor 21 is fixedly coaxially connected to the lead screw 22. The first slide rail 26 is fixed to the mounting plate 27, and the sliding sleeve 25 is threadedly connected to the lead screw 22 and fixed to the second jaw module 24;

[0031] During use, the rotating shaft of the second motor 21 is rotated forward and backward based on the distance and direction that the second jaw module 24 needs to be adjusted. The second motor 21 drives the sliding sleeve 25 to displace along the first slide rail 26 through the lead screw 22, and the second sliding sleeve 25 drives the second jaw module 24 to displace to achieve the displacement adjustment of the second jaw module 24.

[0032] In this embodiment, the first jaw module 23 includes a first sleeve 231 rotatably connected to the lower side of the mounting plate 27, a first connecting block 233 fixed to the bottom of the first sleeve 231, a first movable block 236 capable of sliding up and down on the first connecting block 233, a second slide rail 237 fixed to the first connecting block 233, and two first sliders 235 capable of sliding back and forth on the second slide rail 237. The first sleeve 231 is fixed to the rotating shaft of the first motor 28. A lifting assembly is provided on the first connecting block 233. The lifting assembly is connected to the first movable block 236. The first movable block 236 is provided with two inclined slots arranged in an "eight" shape. The two first sliders 235 are respectively slidably arranged in the two inclined slots through follower wheels. The first movable jaw 234 is fixed to the first slider 235;

[0033] The first movable block 236 penetrates through the first connecting block 233 and is slidably connected to the first connecting block 233;

[0034] When it is necessary to drive the first movable jaw 234 to clamp the U-shaped copper wire, the lifting assembly drives the first movable block 236 to move downward, so that the two inclined slots move downward. The first slider 235 gradually approaches and clamps the U-shaped copper wire as the inclined slots move downward. When it is necessary to release, the lifting assembly is controlled to drive the first movable block 236 to move upward.

[0035] In this embodiment, the lifting assembly is specifically a first cylinder 232. The first cylinder 232 is fixed to the first connecting block 233 and is located inside the first sleeve 231. The telescopic shaft of the first cylinder 232 is connected to the first movable block 236. The lifting adjustment of the first movable block 236 is realized through the first cylinder 232 to ensure the stability of the adjustment;

[0036] In this embodiment, the second jaw module 24 includes a second sleeve 241, a second cylinder 242, a second movable block 243, a second slider 247, a third slide rail 245, and a second connecting block 246. The structures of the second sleeve 241, the second cylinder 242, the second movable block 243, the second slider 247, the third slide rail 245, and the second connecting block 246 and the connection relationships therebetween are the same as those of the first sleeve 231, the first cylinder 232, the first movable block 236, the first slider 235, the second slide rail 237, and the first connecting block 233 of the first jaw module 23. The second sleeve 241 is fixed to the sliding sleeve 25. The second movable jaw 244 is fixed to the second slider 247;

[0037] Similarly, the working principle of the second jaw module 24 is the same as that of the first jaw module 23. Through the telescopic adjustment of the second cylinder 242, the vertical displacement of the second movable block 243 is driven. When the inclined groove of the second movable block 243 is adjusted up and down, the second slider 247 moves towards or away from each other along the third slide rail 245 to drive the second movable jaw 244 to grasp or not grasp the U-shaped copper wire or the I-shaped copper wire.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
