Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 As shown, a logging cable laying bracket includes a bracket disc 1. Three connecting seats 2 are rotatably mounted on the outer surface of the bracket disc 1 along the circumferential direction. Support legs 3 are threadedly installed at the lower end of the connecting seats 2. Since the connecting seats 2 and the support legs 3 are threadedly connected, multiple support legs 3 can be removed when the device is stored for easy storage. At the same time, since triangles have stability, the design of three support legs 3 is adopted to make the device more stable when laying cables. Furthermore, due to the rotatable connection between the connecting seats 2 and the bracket disc 1, the opening and closing angles of multiple support legs 3 can be adjusted arbitrarily. Multiple mounting brackets 4 are fixed at the lower end of the support legs 3 so that the device can be inserted into the ground to increase the stability of the device during use. An upper pulley assembly 5 is provided at the lower end of the bracket disc 1, and a lower pulley assembly 6 is provided between two adjacent support legs 3.
