Percussion wrenches are a very important type of manual wrenches in life and industry. Generally, the hand-held end of the percussion wrench is the percussion end and the front end is the working end to turn a nut or bolt of a certain size. Percussion wrenches are mostly used for assembly and disassembly of large hexagonal screws or nuts, which can be used by outside electricians to load and unload steel frame structures such as iron towers. Let's take a look at this tool intuitively through some pictures of tapping wrenches!

The difference between percussion wrench and electric wrench

The explosion-proof tapping wrench drill chuck involves a drill body, a jacket, a gear ring, a clamping jaw, a wrench and an anti-knock pad. The drill body has a cylindrical shape as a whole. The front and rear ends of the drill body are provided with outer circles of the same diameter. The center of the drill body is provided with a taper hole for docking with an electric drill rod or a main shaft. The outer surface of the drill body is provided with a jacket, and the drill body is provided with a clamping jaw for clamping and a ring gear for controlling the clamping jaw. The drill body is provided with a positioning pin hole for inserting a wrench. The positioning pin hole is used for inserting a wrench to adjust the advance and retreat of the clamping jaws. The wrench is provided with a rubber sleeve and a hanging hole. A circumferential groove is provided on the table surface at the front end of the drill body, and an anti-knock pad is provided in the groove and on the entire table surface.

The new type of impact wrench adds an anti-knock pad on the front face of the drill body, which can ensure not only that it is not afraid of knocking, even if it is knocked without a wrench, it will not affect the service life and accuracy. The matched wrench is covered with a rubber sleeve, which is beautiful and easy to use. The utility model has simple overall structure and high clamping precision.

An electric wrench is a wrench powered by a power source or a battery. It is a tool for tightening high-strength bolts, also known as a high-strength bolt gun. Mainly divided into impact wrenches, torsion shear wrenches, fixed torque wrenches, corner wrenches, angle wrenches. It is easy to operate, saves time and effort, and has a high price.

The electric impact wrench is mainly for initial tightening of the bolt. Its use is very simple, that is, to align the bolt and pull the power switch. The electric torsion shear wrench is mainly used to finally tighten the torsion shear type high strength bolt. Its use is to align the bolt and pull the power switch until the torx head of the torsion shear type high strength bolt is interrupted. The electric fixed Torque Wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. The electric corner wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench specially used to fasten the bolts at the angle of the steel frame. Its use is the same as the principle of the electric torsion shear wrench.

The above content is to introduce to friends the knowledge about the pictures of knock wrenches and the difference between explosion-proof knock wrenches and electric wrenches. Percussion wrenches use the principle of leverage to turn bolts, screws, nuts, and other hand tools that hold the openings or sleeve fasteners of bolts or nuts with threads. It is very convenient to disassemble and assemble the hexagon nuts or bolts in a slightly concave place.
