[0031] like Figure 3 to Figure 4 As shown, it also includes: two groups of slide grooves 10, which are respectively opened on the top area 3; two groups of sliding blocks 11, each group of sliding blocks 11 slides in a group of slide grooves 10, and the two groups of sliding blocks 11 are respectively installed on both sides of the middle area 4, so that the middle area 4 slides on one side of the top area 3.

[0032] like Figure 6 As shown, the sliding block 11 includes: a small sliding block 12 installed at the bottom of the middle area 4; and an inserting block 13 installed on one side of the small sliding block 12.

[0033] like Figure 4 As shown, it also includes: a slot 14, which is opened in the top area 3 and is interconnected with the slide groove 10, and is configured so that when the small slider 12 slides in the slide groove 10, the insert block 13 slides in the slot 14; a dislocation slot 15, which is opened at the top of the slot 14, and is configured so that when the small slider 12 slides along the slide groove 10, the insert block 13 enters the dislocation slot 15.

[0034] Embodiment 2: Figure 4 As shown, the flip assembly includes: a rotating block 16, which is installed at the top of the slide groove 10 and is rotatably connected to the two side walls of the slide groove 10; an arc groove 17, which is opened at the top of the small slider 12 and is configured so that when the plug-in block 13 slides upward to the dislocation groove 15, the arc groove 17 is connected to the bottom end of the rotating block 16; a clamping block 18, which is located in the arc groove 17; a clamping groove 19, which is opened at the bottom end of the rotating block 16 and is configured so that when the plug-in block 13 slides upward to the dislocation groove 15, the clamping block 18 is engaged with the clamping groove 19, so that the middle area 4 rotates with the rotating block 16 to open one side of the wiring clamp body 1.

[0035] The top region 3 is used to wrap the portion of the wiring clamp body 1 where the heads of a group of wires are installed, and the middle region 4 is used to wrap the portion of the wiring clamp body 1 where the middle of another group of wires is installed.

[0036] like Figure 1 As shown, the threaded rod 7 is arranged to penetrate the top end area 3 so that when the insulating member 2 wraps around the wiring clamp body 1 , the threaded rod 7 is driven to rotate by the knob 9 .

[0037] like Figure 1 As shown, it also includes: a rough area 20, located on the side wall of the knob 9, for increasing friction.

[0038] The technical solution provided by the present application is that in the initial state, the middle area 4 and the top area 3 of the insulating member 2 are in a relatively fixed position, and the middle area 4 covers the portion of the wiring clamp body 1 corresponding to the middle of the wire to be installed. At this time, one end of the I-shaped member 5 of the wiring clamp body 1 is a closed pipe for fixing and installing a group of wire heads, and the other end is a pipe with an open end, waiting for the installation of another wire; first, the head of a wire is directly inserted into the closed pipe, and after it is inserted to the deepest point, the knob 9 is turned, and the knob 9 drives the threaded rod 7 to rotate, so that the two groups of arcs are in the closed pipe. The threaded rods 7 in the pipeline are close to each other to clamp and fix the wire heads; in addition, the middle area 4 of the insulating member 2 is pushed to make the sliding blocks 11 on both sides slide in the slide groove 10 of the top area 3. As the small slider 12 moves in the slide groove 10, the plug block 13 installed on one side of the small slider 12 also slides in the slot 14 connected thereto. When the small slider 12 slides to a specific position along the slide groove 10, the plug block 13 enters the dislocation groove 15. At this time, the arc groove 17 opened at the top of the small slider 12 and the rotating block installed at the top of the slide groove 10 are 16 is connected, and the card block 18 located in the arc groove 17 is engaged with the card groove 19 opened at the bottom end of the rotating block 16. In this way, when the middle area 4 is continued to be pushed, the middle area 4 will rotate with the rotating block 16, thereby opening the opening on one side of the wiring clamp body 1, and then the middle part of another wire is directly placed in one end of the opening, and the metal sheet at the top of the power wiring clamp is squeezed downward in an arc shape by using hydraulic pliers, so that the opening is closed and the wires are pressed tightly, thereby completing the fixing of the two wires; when the wires are clamped, the middle area 4 of the insulating member 2 is reset , so that it covers the installed wire part. At this time, the top area 3 wraps the part of the wiring clamp body 1 where a group of wire heads are installed, and the middle area 4 wraps the part of the wiring clamp body 1 where another group of wires are installed in the middle, effectively preventing leakage. At the same time, since the threaded rod 7 runs through the top area 3, when the insulating member 2 wraps the wiring clamp body 1, the user can still drive the threaded rod 7 to rotate by the knob 9, so as to make adjustments when necessary. In addition, the rough area 20 on the side wall of the knob 9 increases the friction, making it easier and more labor-saving for the user to operate.

[0039] This application covers any substitution, modification, equivalent method and scheme made on the essence and scope of this application. In order to make the public have a thorough understanding of this application, specific details are described in detail in the above preferred embodiments of this application, and those skilled in the art can fully understand this application without the description of these details.
