DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] An insulator needle trimming device, such as Figure 1 to Figure 2 As shown, it includes a base 10, a side positioning plate 9, a limit head 8, a positioning rod 6 and a top plate 5;

[0030] The side positioning plates 9 are connected to both sides of the base 10, and scale lines are arranged on the side positioning plates 9; the limit head 8 is movably connected to the side positioning plates 9 and can be fixed to the side positioning plates 9 by a fixing member;

[0031] like Figures 1 to 3 As shown, the positioning rod 6 is fixed on the base 10; the top plate 5 is movably connected to the positioning rod 6, and a through hole 18 is provided in the middle of the top rod; and both sides of the top plate 5 are detachably connected to the limit heads 8. The positioning rod 6 is used to prevent the top plate 5 from tilting.

[0032] Specifically, when in use, place the connector on the base 10 with the insulator needle facing upward. Adjust the position of the limit head 8 so that the limit head 8 is aligned with the top of the insulator needle. Then adjust the position of the limit head 8. At this time, you need to look at the scale line on the side positioning plate 9 to make adjustments. The scale line can indicate the distance that the limit head 8 moves, and the distance moved is the length that the insulator needle needs to be cut. After adjusting the position of the limit head 8, fix the limit head 8 to the side positioning plate 9. Connect the positioning and limit head 8 and allow the insulator needle to pass through the through hole 18 in the middle of the top plate 5. The insulator needle exposed at the top of the top plate 5 is the part that needs to be trimmed. The exposed insulator needle can be cut off with a cutting knife or scissors. At the same time, since the positioning rod 6 can prevent the top plate 5 from tilting, the insulator needle trimmed using this structure has higher consistency.

[0033] In a preferred embodiment, if Figures 1 to 3 As shown, a mounting cavity 17 is provided at the top of the base 10, and a clamping plate 14 and a bidirectional screw 16 are provided in the mounting cavity 17. The bidirectional screw 16 is rotatably connected to the base 10, and the clamping plate 14 is threadedly connected to both sides of the bidirectional screw 16. The threads on both sides of the bidirectional screw 16 have opposite rotation directions. The clamping plate 14 is used to clamp and fix the connector. When in use, the bidirectional screw 16 is rotated, and since the threads on both sides of the bidirectional screw 16 have opposite rotation directions, the clamping plates 14 will move closer to or away from each other. The position of the connector can be fixed by controlling the clamping plates 14 to clamp each other and clamp the connector. At the same time, the bidirectional screw 16 can ensure that the clamping plates 14 move synchronously, so that the clamping plates 14 can clamp the connector in the middle.

[0034] In a preferred embodiment, if Figures 1 to 3 As shown, two bidirectional screws 16 are provided, one end of which extends out of the base 10 and is fixedly connected to the main pulley 13 and the rotating head 11, and one end of the other bidirectional screw 16 extends out of the base 10 and is fixedly connected to the secondary pulley 4, and the main pulley 13 and the secondary pulley 4 are connected by a belt 3. The two bidirectional screws 16 are provided to ensure the stability of the movement of the splint 14. The main pulley 13 and the secondary pulley 4 are provided to facilitate the simultaneous rotation of the two bidirectional screws 16. When in use, the bidirectional screw 16 with the main pulley 13 is rotated, and the rotating head 11 can conveniently rotate the bidirectional screw 16 by hand. During the rotation process, the main pulley 13 drives the secondary pulley 4 to rotate through the belt 3, thereby realizing the synchronous rotation of the two bidirectional screws 16.

[0035] In a preferred embodiment, if Figures 1 to 3As shown, the fixing parts are screw rods 21 and nuts 22, a vertical positioning groove 15 is provided in the middle of the side positioning plate 9, the screw rod 21 is fixed to one side of the limit head 8 and movably arranged in the positioning groove 15, and the nut 22 is used to lock the limit head 8 with the screw rod 21 and the side positioning plate 9. By setting the screw rods 21 and the nuts 22, the limit head 8 and the side positioning plate 9 can be stably locked to prevent the position of the limit head 8 from changing, thereby ensuring the stability of the limit head 8.

[0036] In a preferred embodiment, if Figures 1 to 3 As shown, a compression spring 12 is arranged outside the positioning rod 6, one end of the compression spring 12 is connected to the top plate 5, and the other end is connected to the base 10. The compression spring 12 is used to realize the reset of the top plate 5. At the same time, the compression spring 12 always pushes the top plate 5 upwards, which is convenient for adjusting the position of the limit head 8.

[0037] In a preferred embodiment, if Figure 1 As shown, the top of the positioning rod 6 is fixedly connected with a positioning head 7. The positioning head 7 is used to prevent the top plate 5 from falling off the positioning rod 6, thereby ensuring the stability of the top plate 5.

[0038] In a preferred embodiment, if Figures 1 to 4 As shown, the side positioning plate 9 is an L-shaped structure, and the bottom of the side top plate is movably connected to the base 10; a guide block 19 and a limit block 20 are fixedly connected to the side of the limit head 8 close to the top plate 5, and the guide block 19 is located above the limit block 20. An installation gap is formed between the guide block 19 and the limit block 20, and the top plate 5 is stuck in the installation gap. Specifically, when the top plate 5 needs to be stuck in the gap between the guide block 19 and the limit block 20, it is only necessary to pull the side positioning plates 9 on both sides outward and stick the two sides of the top plate 5 into the installation gap, and then loosen the side positioning plates 9 to reset the side positioning plates 9, and the side positioning plates 9 stably clamp the top plate 5 in the middle.

[0039] In a preferred embodiment, a tension spring 2 is provided between the side positioning plates 9 on both sides, and the two ends of the tension spring 2 are respectively connected to the bottom of the side positioning plates 9 on both sides. The tension spring 2 is used to achieve automatic reset after the auxiliary side positioning plate 9 is released.

[0040] In a preferred embodiment, if Figure 4 As shown, the cross section of the limit block 20 is a triangular structure. Specifically, when in use, after adjusting the position of the limit head 8, the top plate 5 is directly pressed downward. After the top plate 5 contacts the limit block 20, the top plate 5 will squeeze the limit block 20 to both sides and separate the side positioning plates 9 on both sides. Finally, when the top plate 5 moves to the position of the installation gap, it will be stuck in the installation gap. This design can effectively improve the use efficiency.

[0041] In a preferred embodiment, movable shells 1 are fixedly connected to both sides of the bottom of the base 10, and the bottom of the L-shaped side positioning plate 9 is movably connected in the movable shell 1. The design of the movable shell can ensure the smooth movement of the side positioning plate 9 and ensure the stability of the side positioning plate 9.
