In short, it acts as a circuit breaker. However, the existing outdoor pole-mounted load switches have some deficiencies. For example:

[0004] There is no limit set for the connection mechanism at the connection, which may cause the connection to be insecure during the use of the device, resulting in the loosening and falling off of the interface. And load switches are all high-voltage devices. Once electric leakage occurs, it will lead to serious safety accidents. Content of the Utility Model

[0005] The purpose of the utility model is to provide a limb rehabilitation assistor for stroke patients with a massage effect to solve the problem that in the existing devices on the market, an external cable passes through a wiring sleeve and is connected to the wiring end of a conductive rod, and the wiring sleeve is connected to an insulating sleeve to form a protection for the connection between the cable and the conductive rod;

[0006] There is no limit set for the connection mechanism at the connection, which may cause the connection to be insecure during the use of the device, resulting in the loosening and falling off of the interface. And load switches are all high-voltage devices. Once electric leakage occurs, it will lead to serious safety accidents.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An incoming line device for an outdoor pole-mounted load switch, comprising a cable connector, an insulating sleeve head, a limit bolt, an incoming line column and a closing and opening rod;

[0008] The insulating sleeve head is installed on the left side of the cable connector, and an incoming line column is arranged on the left side of the insulating sleeve head. A sealing rubber cover is installed above the left side of the insulating sleeve head;
