It should be noted that, as shown in fig. 1, in the embodiment of the present invention, an end of the first rod 72 away from the second rod 74 is pivotally connected to the fixing ring 71 through a rotating shaft, and the fixing ring 71 is sleeved and fixedly connected to the outer periphery of the supporting rod 10. The rotating shaft is a bolt, the bolt is provided with a lock nut in threaded fit with the bolt, and the lock nut can fix one end of the first rod 72, which is far away from the second rod 74, on the bolt head of the bolt. When the first rod body 72 rotates to preset angle a (the first rod body 72 and the support rod 10 form an included angle of 45 degrees) relative to the support rod 10, the lock nut is rotated to fix the end, far away from the second rod body 74, of the first rod body 72 on the bolt head, so that the support seat 73 is in butt contact with the piece 80 to be clasped in the radial direction of the piece 80 to be clasped, the support seat 73 cannot move relative to the piece 80 to be clasped (equivalently, the support seat 73 is fixed on the piece 80 to be clasped), and the auxiliary support frame 70 can support the support rod 10, thereby ensuring normal work of the fixed support.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the driving piece can drive the holding part to hold tightly along the axial direction of the axial through hole and to hold tightly and to treat the holding piece, so that the fixed support is connected with the holding piece to be held tightly, therefore, an operator only needs to operate the driving piece and keeps away from the holding device, the fixed support is not required to be mounted on the telegraph pole by hands or detached near the position of the electrified body, the risk of electric shock of the operator is reduced, and the safety during mounting of the fixed support is improved. In addition, the fixing bracket is often bound and fixed on the telegraph pole by adopting a hinge mode in the prior art, however, the hinge is very inconvenient to tighten and is difficult to tighten in place, so that the labor intensity of operators is increased, and a better fixing effect cannot be achieved. This application adopts the portion of holding tightly to hold the wire pole, and this kind of fixed mode is more reliable than the fixed mode of hinge, and stability is higher to ensure the work that the fixed bolster can be normal.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
