Referring to fig. 1 and fig. 2, the present embodiment provides a current collector bracket, including a bottom plate 100; the bottom plate 100 is provided with a lifting platform 200, and the movement direction of the lifting platform 200 is perpendicular to the bottom plate 100; a U-shaped mounting frame 300 is arranged on one side of the lifting platform 200 far away from the bottom plate 100, a mounting seat 310 is arranged on the mounting frame 300 at the inner side of the opening, and the mounting seat 310 is connected with the mounting frame 300 through a hinge shaft 311; one side of the mounting bracket 300 is provided with an inner gear 320 corresponding to the hinge shaft 311; the inner gear 320 is fixedly connected with the mounting bracket 300 and is positioned outside the mounting bracket 300; a slidable axial center 312 is arranged inside the hinge shaft 311; the shaft center 312 is provided with external teeth corresponding to the internal gear 320; the hinged shaft 311 is in tooth connection with the shaft center 312, and corresponding internal teeth are arranged in the hinged shaft 311 corresponding to the shaft center 312; a pressure spring 313 which is pressed against the shaft center 312 is also arranged in the hinge shaft 311; the shaft 312 can be completely inserted into the hinge shaft 311 by compressing the compression spring 313. The shaft center 312 is compressed into the hinged shaft 311, so that the shaft center 312 is separated from the internal gear 320, the mounting seat 310 is rotatably adjusted relative to the mounting frame 300 through the hinged shaft 311, after the adjustment is completed, the external force is removed, the pressure spring 313 ejects the shaft center 312, and the shaft center 312 is matched with the fixedly mounted internal gear 320 to perform anti-motion limiting on the mounting seat 310.

In a preferred embodiment, a corresponding compression post 314 is arranged at one end of the shaft center 312, which is far away from the compression spring 313, the diameter of the compression post 314 is smaller than the inner diameter of the internal gear 320, and the length of the compression post 314 is larger than the axial length of the internal gear 320, so that the compression post 314 is ensured not to be in contact with the internal gear 320 when compressing the shaft center 312, and a part of the compression post is not positioned outside the internal gear 320, which is beneficial for operation.

In a preferred embodiment, the elevating platform 200 is connected to the base plate 100 by an elevating mechanism; the lifting mechanism comprises a first threaded rod 210 vertically connected with the lifting platform 200 and a second threaded rod 110 vertically connected with the bottom plate 100; the first threaded rod 210 is threaded in the opposite direction to the second threaded rod 110; the first threaded rod 210 is connected with the first threaded rod 110 through a handle with corresponding internal threads; since the first threaded rod 210 and the second threaded rod 110 have opposite thread directions, the first threaded rod 210 and the second threaded rod 110 can move towards the handle or away from the handle simultaneously by rotating the handle, so as to achieve the purpose of adjusting the height.
