Detailed ways

Example

Fig. 1 is a schematic diagram of an embodiment of the live loading and unloading clamp of the present invention when the wire is not clamped, Fig. 2 is a schematic diagram of the embodiment of the live loading and unloading clamp of the present invention when the wire is clamped, and Fig. 3 is a schematic diagram of the live loading and unloading wire of the present invention Enlarged view at A of the clip embodiment. As shown in the figure, the utility model provides a live loading and unloading wire clip, including a wire clip body 1, one end of the wire clip body 1 is provided with a fixing clip 2, and the fixing clip 2 is set in a C-shaped structure, and the other side of the wire clip body 1 One end is provided with a fixed frame 3, and the clamp main body 1 is also provided with a connector 14, the connector 14 is located on the same side of the fixed clip 2 and the fixed frame 3, and the connector 14 is provided with a threaded hole, and the threaded hole is provided with Tighten the bolt 15, the fixed frame 3 is provided with a connecting rod 4, the end of the connecting rod 4 near the fixed clip 2 is provided with a movable clip 5, and the side of the movable clip 5 near the fixed clip 2 is set as an arc groove, and when clamping When conducting wires, the contact surface is closely attached to the wires so that the wires are evenly stressed without damaging the wires. The other end of the connecting rod 4 is provided with a movable clamping mechanism. The movable clamping mechanism includes a rotating rod 6 and a fixed frame. 3-phase connection handpiece 7 and a pair of support plates 8 symmetrically arranged in the handpiece 7, one end of the rotating rod 6 is rotationally connected with the connecting rod 4, and the other end of the rotating rod 6 passes through the support plate 8 and the opening of the handpiece 7 in turn. One end, and the end is provided with a ring 9, a first spring 10 is provided on the rotating rod 6 between the support plates 8, a spring pin 11 for resisting the first spring 10 is provided on the rotating rod 6, and a spring pin 11 is provided on the handpiece 7 There are stoppers 12 for resisting the spring pins 11. There are at least three stoppers 12 arranged evenly on the hand piece 7. A second spring 13 is arranged on the connecting rod 4 between the movable clip 5 and the fixed frame 3; When the spring pin 11 is pressed against the end of the first spring 10 away from the connecting rod 4 and simultaneously against the support plate 8, the first spring 10 and the second spring 13 are all in a compressed state, and when the spring pin 11 approaches the fixed clip 2 When moving in the direction, the first spring 10 is further compressed, and the second spring 13 is further released. When the second spring 13 is released, a force is generated to make the movable clip 5 close to the fixed clip 2, so that the worker does not have to use too much force. Just can spring pin 11 be stuck on the stopper 12.
