Explosion-proof tools and explosion-proof screwdrivers are made of aluminum bronze alloy and beryllium bronze alloy, which are the style of our conventional explosion-proof screwdrivers. The working end is slotted (cross) and rubber handle. A tool used to turn a screw to force it into position, usually with a thin wedge head, which can be inserted into the slot or notch of the screw head - also known as "screwdriver". There are two main specifications: one word (minus sign) and one cross (plus sign). There are also common hexagon screwdrivers, including inner hexagon and outer hexagon. Explosion-proof screwdriver is also divided into traditional screwdriver (English: Screwdriver) and ratchet screwdriver (electric screwdriver) (English: Ratchet Screwdriver). The traditional explosion-proof screwdriver consists of a plastic handle plus an iron bar that can lock the screw, while the ratchet screwdriver consists of a plastic handle plus a ratchet mechanism. The latter allows the iron bar for locking the screw to idle clockwise or anticlockwise, so as to promote the efficiency of locking the screw through the idle function, without having to turn the power driver (hand) back to the original position one by one. Explosion-proof screwdriver also includes explosion-proof striking screwdriver and explosion-proof star screwdriver
