An explosion-proof ratchet wrench is an explosion-proof tool used for manual tightening of screws. There are many types and specifications such as single head and double head. It is mainly made of different sizes. The two kinds of plum blossom sets, the plum blossom set and the plum blossom set, are connected by the engagement of the female key and the male key of the hinge key. Explosion-proof ratchet wrench is made of copper alloy. Due to the special physical properties of copper alloy (i.e., it does not contain carbon and has good thermal conductivity), the heat generated when the ratchet wrench and mechanical parts rub or impact is quickly absorbed and conducted away, and Copper itself is relatively soft compared to other non-ferrous metals. It has good yielding properties during friction and impact, and is not easy to produce tiny metal particles, so we can hardly see sparks. Therefore, explosion-proof ratchet wrenches are also called spark-free ratchet wrenches, which are modified wrenches. Since a plum-shaped set has two specifications of plum-shaped through holes, it can be used to tighten and tighten screws of two specifications, thus expanding the scope of use and saving raw materials and labor costs. The movable trigger can adjust the wrench in a timely and convenient manner. Angle. This wrench can be used for tightening screws and has the advantages of strong applicability, easy operation and low price. Specifications,,,,,,,,,,,,,,,
