AI Technical Summary
The fixed length of the rocker arm in existing manually driven crank handles makes them difficult and strenuous to use under heavy loads.
The combination design of the rotating sleeve, rotating rod, first gear, second gear and threaded rod of the aluminum alloy disc-type crank handle enables the handle length to be adjustable, increases the torque and prevents the handle from rotating through the limiting structure.
It enables more effortless operation under heavy loads, increases torque through an adjustable-length crank handle, and effectively prevents the handle from rotating, thus improving ease of use.
