The rod head 3432 is rotatably connected to the second connecting portion 342 through a rotation shaft, so that when the lower clamping rod 12 moves to keep the vertically upward clamping rod 11, the lower clamping rod 12 firstly pushes the second connecting portion 342 to move, and when pushing in the second connecting portion 342, the second connecting portion 342 pushes the movable rod 343 to keep moving, and the movable rod 343 pushes the first protruding portion 412 or the second recessed portion 511 to keep rotating to clamp the electric wire to be clamped.
In use, when the lower clamping bar 12 keeps moving vertically upwards to the clamping bar 11, the lower clamping bar 12 pushes the second connecting parts 342 at two sides to keep moving at the same time, and pushes the movable bar 343 to keep moving through the second connecting parts 342, because the rod head 3432 of the movable bar 343 is rotationally connected to the rod body 3431, and the first connecting part 341 which is kept connected with the rod head 3432 is rotationally connected to the outer wall of the first protruding part 412 or the second recessed part 511, the first protruding part 412 or the second recessed part 511 can be pushed to rotate towards the first recessed part 411 or the second protruding part 512 through the rod body 3431, thereby realizing the clamping of the electric wire.
The elastic coefficients of the compression spring and the extension spring meet the technical requirements of the technical scheme of the utility model.
Those skilled in the art will appreciate that other similar connections may implement the present utility model. Such as welding, bonding, or bolting.
While certain exemplary embodiments of the present utility model have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the utility model, which is defined by the appended claims.
