Stable adjusting mechanism for tension of winch cable

The utility model relates to a winch cable tension stable adjusting mechanism which comprises an internal thread bottom frame, a top plate is fixedly installed on the top of the internal thread bottom frame, and the winch cable tension stable adjusting mechanism is arranged on the top of the internal thread bottom frame. The winch cable tension stable adjusting mechanism comprises a motor fixedly installed on the right side of the internal thread bottom frame, and a sliding groove is formed in the top plate. According to the winch cable tension stable adjusting mechanism, a winch cable penetrates into the position between a left pulley and a right pulley and then penetrates into the position between two first rotating rollers from the top of a second rotating roller, at the moment, a limiting frame and a top limiting frame limit the winch cable, and the effect of preventing the winch cable from derailing and falling is achieved; the motor drives the lead screw to rotate reversely to force the internal thread
