Tips: The use of universal joint socket adapter
The square socket part of the universal joint can be moved back and forth or left and right. For use with the matching ratchet handle and the socket, the rotation angle of U-joint can be changed freely. Its working principle is basically the same as that of the universal joint used in the drive shaft of the front-rear drive car.
In many places on the vehicle, the ratchet cannot be inserted to fasten or loosen the bolt or nut. At this time, the universal joint will provide the greatest convenience. It can provide more space for changing direction than the bendable joint.
When using a ratchet with a universal joint, do not tilt the handle to a large angle to apply torque. It should be used close to the vertical position, because too large a deflection angle will easily reduce the torque transmission efficiency. In addition, when using universal joints to loosen or tighten screws, be sure to check whether there is any debris in the connection part or hole, and clean it up in time to avoid injury to yourself due to unstable connection of the tool.
