Adjustable wrench is a kind of hand tool commonly used in pipeline installation, mechanical maintenance and other occasions, which can be adjusted according to the need to adapt to different specifications of nuts and bolts.
1. Handle: The handle of the adjustable wrench is usually made of durable and non-slip material, which is convenient for the operator to grasp and apply force. The handle should be designed with ergonomics in mind to provide a comfortable grip and handling experience.
2. Adjustment device: The adjustment device is a key part of the adjustable wrench, which allows the user to adjust the size of the wrench as needed. Common adjustment devices include spiral adjustment and gear adjustment.
3. Pull rod: The pull rod is the part that connects the handle and the adjusting device, which plays the role of transmitting force. The length and diameter of the tie rod will affect the overall rigidity and durability of the wrench.
4. Fixture: The fixture is used to fix the part of the target object, such as nuts or bolts. The design of the fixture should take into account the shape and size of the object to ensure sufficient clamping force and stability.
1. Handle: The main function of the handle is to provide grip strength to help the operator maintain stability during operation. In addition, the design of the handle can also provide a non-slip function to prevent slipping when applied.
2. Adjustment device: The adjustment device allows the user to quickly and easily adjust the size of the wrench as needed. For example, when nuts and bolts of different sizes need to be tightened or loosened, the size of the wrench can be easily adjusted through the adjustment device.
3. Pull rod: The main function of the pull rod is to transfer force. It combines the operator's grip force with the adjustment of the regulating device so that the force can be effectively transferred to the fixture. The design of the tie rod should take into account the operator's application mode and force to ensure that the force can be transmitted efficiently.
4. Fixture: The main function of the fixture is to fix the target object, such as nuts or bolts. Its design should take into account the shape and size of the object to ensure adequate clamping force and stability. The clamp usually has a self-locking function to prevent the object from falling off during exertion.
