There is no need to repeatedly tighten multiple sets of bolts as in the comparison documents. It is simple and convenient to use.

[0017] ② The clamping force is constant and will not damage the wire. This is because the clamping of the transmission lines and wires relies on the compression and clamping of the thickened part with limited thickness. The clamping force can be adaptively changed by the thickness of the thickened part. Compared with the method of tightening bolts in the reference document, the clamping force is constant and stable within a range, causing less damage to the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The locking rod 3 is a bolt.

[0039] First embodiment:

[0040] When in use, the first clamping body 1 is used to clamp the wire 9, and the second clamping body 2 is used to clamp the transmission line 8. When clamping the wire 9, first move the rotating column 13 out of the hook 12, release the limit on the outer embedded block 16, and then slide the outer embedded block 16 out of the slide groove 19;

[0041] like Figure 7 As shown, the metal wire portion of the wire 9 is embedded into the inner wire position 151 of the embedding block 15, and then slid into the outer embedding block 16 again in the slide groove 19, and then the rotating column 13 is restored to the hook 12 to complete the position limiting of the outer embedding block 16, and the flat portion 132 of the rotating column 13 is in contact with the locking surface 163 of the outer embedding block 16;

[0042] like Figure 6 As shown, according to the above principle, the transmission line 8 is embedded into the second clamping body 2; the rotating column 13 and the deflection frame 14 on the second clamping body 2 are deflected as a whole, so that the thickened portion 131 on the rotating column 13 contacts the locking surface 163 of the outer embedded block 16;

[0043] like Figure 1 As shown, the locking rod 3 is inserted into the deflection frame 14 of the second clamping body 2, and the limit head 31 of the locking rod 3 is limited by the semi-ring 142 of the second clamping body 2. The rotating handle 4 on the locking rod 3 faces the first clamping body 1, and then the rotating column 13 and the deflection frame 14 of the first clamping body 1 are deflected as a whole, so that the thickened portion 131 on the rotating column 13 contacts the locking surface 163 of the outer embedded block 16. At the same time, the vertical through groove 144 of the deflection frame 14 passes through the outside of the rotating handle 4, and then rotates around the axis of the locking rod 3 to lock. The rod 3 and the handle 4 are integrally connected until the handle 4 is embedded in the recess 143 on the deflection frame 14 on the same side. Due to the establishment of the thickened portion 131, when the rotating column 13 deflects the frame 14 as a whole, the space between the inner block 15 and the outer block 16 will be compressed and then move closer to each other to clamp the transmission line 8 and the take-off line 9. When clamping, there is an outward expansion elastic force between the two deflection frames 14, so the handle 4 will not fall out of the outer recess 143 under the action of this elastic force, thereby ensuring the stability of its connection;

[0044] The transmission line 8 and the pickup line 9 are effectively electrically connected via two groups of contact-connected embedded blocks 15 and the electrical connection posts 154 thereon.

[0045] Second embodiment:

[0046] The other principles of the second embodiment are consistent with those of the first embodiment, with the only difference being that the locking rod 3 is a bolt, and the locking rod 3 with a locking bolt structure penetrates the two half rings 142 on the first clamping body 1 and the second clamping body 2; the two half rings 142 on the first clamping body 1 and the second clamping body 2 are locked, and then the two deflection frames 14 are locked. At this time, due to the establishment of the thickened portion 131, when the rotating column 13 and the deflection frame 14 are rotated as a whole, the space between the inner block 15 and the outer block 16 will be compressed and then moved closer to each other to clamp the transmission line 8 and the take-off line 9. The transmission line 8 and the take-off line 9 are effectively electrically connected through two groups of contact-connected inner blocks 15 and the power connection posts 154 thereon.

[0047] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
