Tips: What is a ratchet screwdriver?

A ratchet screwdriver is a manual screwdriver with a handle operated by the reciprocating motion and a removable screwdriver bit. The front end of the handle is provided with a ratchet base. On the ratchet base, there are two reverse swivel pawls and a pick for controlling the position and state of the pawls. The tail of the shaft is provided with a ratchet sleeve which is mounted on the ratchet base and meshes with at least one of the two ratchet pawls. A ratchet screwdriver uses a ratchet mechanical device. The role of a ratchet is to make the screwdriver turn in only one direction, so that when screwing, the screw can be tightened by turning in a positive direction, and when changing the direction, the screw does not follow, just handle to reverse rotation, so it is very convenient to operate, and saves energy. In particular, using only micro angle to turn the handle to tighten or loosen a screw, greatly improves the working efficiency, reduces the labor intensity, and shorten the work time.

The difference between ordinary screwdriver and ratchet screwdriver is whether there is ratchet device or not. The ratchet device can make the user operation easy, especially applicable to high strength tightening and loosening screws again and again. The ratchet screwdriver handle is a lever, the forces acting on the end of the screwdriver to much larger than ordinary screwdriver, therefore it is more efficient. However, compared to the ordinary screwdriver, the ratchet screwdriver is also more difficult to carry and use in a narrow environment because of the ratchet device.
