Description

The field > is a description of a technique related to analogues > It is known that it is more difficult to loosen at all times, and the increase in resistance to loosening caused by the change in friction of the pile is most often Familiar people: When the problem of vehicle wheels is to loose all the concerns, and if they are, they usually become weaker after the cap or bolts are locked. In the situation, people have methods other than the traditional one. One of the more common methods is to remove the attachments (such as i-nuts and bolt devices (commonly known as wrenches) anyway. They will try to increase the equipment for loosening the nut. A pipe body or a weak body_man hardly twists or hammers the pine hardly. These increase in a short time, and the bolts are exposed to the bolts with a clear degree to increase the current vehicle. It must be fixed to the wheel bolts. Department of phase, tire shop, it is easy to attach it. If the fifth, the description of the invention (i) < Invention of the screw or phase of the invention > The thread also has friction over time, which causes this problem to be fixed. For example, the inspection must be faced. Because the lock is locked, and the tool is locked after winter, it is normal or relatively loose to read most of the moment of the screw segment for a long time.

Page 4 5 Description of the invention (2): It is very laborious and easy to cause harm. After applying a strong force ~ loosening the screw inspection, many situations will happen very quickly. The person who is on the tool must now reduce the torque. This may be difficult to control without lifting. The result is usually the force of the nut, tool or the operator. Most tools are only in contact with the nut or the screw head. This will cause most tools to be separated from the nut and bolt head, usually causing damage to the contact surface between the screw head and the tool. A method often used for tightly coupled nuts is to apply torque to the bolt, so the bolt is exposed to heat, mild shock and / or chemical solution. These measures are usually accompanied by the torque when the torque is applied. The most difficult resistance is, in fact, especially if the force application is fixed: designed to keep the applied force 必须, it must be caused by: the force is applied to complete the holding of the torque. Another problem is often to increase the lock. Tight or loaded, that is, the space when rotating nuts and bolts ^ the relationship between nuts and bolts is also limited.
