[0002] A cable structure is a spatial structure form formed by combining a high-strength flexible film material with a support system to form a stable curved surface with a certain stiffness and capable of withstanding a certain external load. A connector refers to a direct connection device between two independent parts. For example, it can also be connected with a hook. Narrowly speaking, it refers to a direct connection device between the end faces of two rotating parts. A connector can connect or cut off the power of an engine. Connectors can be basically divided into three types: non-separable type, separable type and safety type. A connector is composed of a connection plate, two connection pins symmetrically arranged on one side of the connection plate, and a tool joint installed at the middle position relative to the connection pins on the other side.

The end of the rod body has a cone, an axially fixed end, and an external thread. The cone is arranged at one end of the axially fixed end. The end of the rod body has an external thread. The axially fixed end of the connector is a column body with a hollow interior. There is an internal thread inside the axially fixed end of the connector. The axially fixed end of the connector is connected to the radially fixed end of the connector through a flange plate, a limit block I, and a spring. The radially fixed end of the connector is a column body with a hollow interior. An annular limit block II is arranged on the outer surface of the radially fixed end of the connector.
