In order to achieve the above purpose, the utility model provides the following technical solutions: a power transmission and transformation clamp, including a first bow frame and bolts, the inside of the first bow frame is provided with convex grooves, and the bolts are installed on the second On a bow-shaped frame, the surface of the first bow-shaped frame is provided with a waterproof device, and the first bow-shaped frame is provided with stud holes, and the first bow-shaped frame and the second bow-shaped frame are connected by bolts, and the second bow-shaped frame is connected by bolts. A groove is provided inside the bow frame, a circular washer is provided on the second bow frame, and a buffer device is provided below the circular washer.

Preferably, the bolts are composed of studs and nuts.

Preferably, the convex groove has a double-layer structure, and a wire protection buffer is provided at the gap between the inner wall and the outer wall of the convex groove.

Preferably, there are six bolts and stud holes, and the six bolts are fastened to the left and right ends of the first arch frame and the second arch frame through the six stud holes respectively.

Preferably, there are two convex grooves, and the two convex grooves are installed in the first arched frame.

Compared with the prior art, the beneficial effects of the utility model are: the structure of the utility model is scientific and reasonable, and the utility model is convenient and efficient; The device protects the wire from being damaged by rain, snow and dew. At the same time, through the cooperation of the convex groove and the groove, the function of pressing the wire is realized, ensuring that the wire is not easy to loosen. Make the structure of the power transmission and transformation hook clamp more stable; the nut and the circular washer are provided with a buffer device to protect the surface of the second bow frame from being scratched by the nut, and at the same time compress the nut to make the power transmission and transformation and hook clamp The structure is stable; this new type of arch provides a basic tightening tool that can be used safely, which improves the guarantee of the operation quality of the safety device. At the same time, it can also reduce the labor intensity of the operator and reduce the repetition of frequent operations.
