Abstract: An anchor winch has a casing assembly, a motor, a capstan and a chain. The casing assembly has a casing, a guiding cover, a spring and a guiding rail. The guiding cover is mounted on the casing and selectively opens. The spring is connected to the casing and the guiding cover and makes to guiding cover to be capable of opening at any angles. The guiding rail is mounted on the casing adjacent to the guiding cover. The motor is mounted on the casing. The capstan is mounted rotatably on the casing and is driven by the motor. The chain is mounted through the casing and is wound on the capstan. The spring achieves a somewhat loose connection between the casing and the guiding cover, which provides a resilient force preventing the guiding cover from being damaged by the inadvertent impact from the moving chain.

Abstract: An automatic winder has a base, motor, a transmission device and a reel. The motor is mounted on the base. The transmission device connects to the motor and has a pair of high-speed gears and a pair of low-speed gears. The reel is mounted on the transmission device and has a spool of a cord. When the motor is overloaded, the motor connects to the pair of the low-speed gears to drive the reel to prevent the break of the motor.
