What are the considerations for Adjustable Wrench?

Adjustable Wrench, whose opening width can be adjusted within a certain range, is a tool used to tighten and loosen nuts and bolts of different specifications. The movable wrench is composed of a head and a handle, and the head is composed of a movable plate lip, a rigid plate lip, a plate mouth, a turbine and a shaft pin. The size of the plate opening can be adjusted by rotating the turbine. Specifications are expressed by length x maximum opening width (unit: mm).

Adjustable Wrench

Requirements:

(1) When pulling a large nut, a large torque is often used, and the hand should be held near the tail of the handle.

(2) When pulling the small nut, the torque used is not large, but the nut is too small and slips easily, so the hand should be held close to the head of the board. This allows the scroll to be adjusted at any time to tighten the movable lip to prevent slipping.

(3) The adjustable wrench cannot be reversed to avoid damaging the lip of the plate, nor can it be extended by a steel pipe to increase the torque.

As an Impact Wrench Manufacturers, let me share some notes:

There are many types and specifications of wrenches, although there are many types of open-end wrenches, plum wrenches, adjustable wrenches, socket wrenches, torque wrenches and so on. But the methods of use and precautions are similar.

1. No matter what kind of wrench. The best effect is to pull, if it must be pushed. It can only be pushed with the palm of your hand, and your fingers must be spread out to prevent the bolts or nuts from loosening and hurting your fingers. To get the most torque. The direction of the pulling force must be at right angles to the wrench handle.

2. When using an adjustable wrench. The specifications should be selected according to the size of the nut. When using, hold the handle with your right hand. The further back the hand, the less effort it takes to pull it. When pulling the large nut, a large torque is required, and the hand should be held near the end of the handle. When pulling the small nut. The required torque is not large, but the nut is too small and easy to slip. Therefore, the hand should be held close to the head. And the worm gear can be adjusted at any time to tighten the loose lip to prevent slipping.

3. When using a spanner. The movable jaws of the wrench should be subjected to thrust, while the jaws should be fixed and subjected to pulling force, that is, when the wrench is pulled. The movable jaw faces inward: the force must be uniform to avoid damaging the edges of the wrench or bolt and nut. Accidents caused by skidding.

4. Avoid using excessive force when using a wrench. otherwise. It may cause slipping and hurt the human body.

5. The wrench must not be used as a pry bar or hand hammer.

6. When pulling the rusted nut. Drop a few drops of kerosene or motor oil on the nut. After a period of time. Just twist it. When it cannot be screwed, never use a steel pipe to cover the handle of the adjustable wrench to increase the torque. Because it is easy to damage the loose lip or nut, the nut cannot be removed.

7. When you need to use a wrench to climb. To pass by rope, do not throw it up or down.
