1 The Plum wrench defines that both ends of the plum wrench are annular, and its inner hole is formed by two regular hexagons staggered 30 ° concentric with each other. Many plum wrenches have elbows, and the common elbow angle is between 10 ° and 45 °. From the side, the rotating bolt part and the handle part are staggered. This structure is convenient to disassemble bolts and nuts assembled in the recessed space, and can provide operation clearance for fingers to prevent scratches. For supplementary tightening and similar operations, a plum wrench can be used to apply large torque to bolts or nuts. There are various sizes of plum wrenches. When using, you should choose wrenches corresponding to the size of bolts or nuts. Because the wrench wrench jaw is double hexagonal, it can be easily assembling Bolt/nut. This can be reinstalled in a limited space.

The product must pass quality inspection and verification to avoid personal injury caused by product quality problems during use.

How to use the plum wrench: when using the plum wrench, push the connection between the plum wrench and the bolt with the left hand to keep the plum wrench fully matched with the bolt to prevent slippage, hold the other end of the plum wrench in the right hand and force it. Plum wrench can surround the head of bolts and nuts, so it will not damage the bolt angle and can exert a large torque.

3 note when using the wrench, it is forbidden to increase the torque by extending the length of the wrench with the lengthened Pipe sleeve. It is forbidden to beat the wrench to increase the torque, otherwise it will cause tool damage.
It is forbidden to use plum wrenches with cracks and serious wear of inner holes.
