The head is penetrated with a groove, and a rotatable ratchet ring is arranged in the groove, and the ratchet ring One side is provided with a ratchet unit, which can be used to control and switch the rotation direction of the ratchet ring, wherein the ratchet ring is provided with a through hole for the user to set a batch of head inserts in the through hole. The batch head locks or loosens a workpiece.

However, the conventional ratchet wrench is designed with a through hole, which not only makes it difficult for the user to push the bit to a predetermined position when installing the bit, but it is also not convenient for the user to take out and replace the bit. Some people in the market add a magnetic element to the through hole to position the batch head through magnetic attraction. However, this method is limited by the weak magnetic force, the positioning effect is not good, and it cannot be used for external coating. Bits made of layers or non-magnetic materials. On the other hand, the magnetic piece is usually a disk-shaped or rectangular-shaped magnet. To attach or embed the magnet in the through hole will increase the assembly of the conventional ratchet wrench The difficulty of the above-mentioned combination method is not good, and once the conventional ratchet wrench is impacted by an external force, the magnetic part is likely to come out of the through hole. Therefore, the author of this case, after observing the above shortcomings, believes that the existing The ratchet wrench is really necessary for improvement, and the original creation was born.

The purpose of this creation is to provide a ratchet wrench capable of quickly disassembling and assembling a bit, which allows the user to quickly and conveniently position a batch on the ratchet wrench and quickly take out the bit by the ratchet wrench.
