Description

Technical Field

[0001] The invention relates to the technical field of pipe clamps, in particular to a quick-adjustable movable-jaw pipe clamp. Background Art

[0002] Pliers are hand tools used to clamp and fix workpieces or twist, bend and cut metal wires. There are many types of pliers and they are widely used. They are an indispensable hand tool for clamping and shearing workpieces in various industries such as assembly, repair and installation. But they have a common basic structure, that is, any hand pliers are composed of three parts: pliers head, pin and pliers handle. The basic principle of pliers is to use two levers, cross-connected with pins at a point in the middle, so that the two ends can move relative to each other. As long as the tail end is operated by hand, the other end can clamp the object. In order to reduce the force used by the user during operation, according to the principle of lever in mechanics, the pliers handle is usually made longer than the pliers head, so that a stronger clamping force can be obtained with less force to meet the use requirements.

[0003] The pipe clamp is a tool that converts clamping force into torque and is used to clamp and rotate steel pipe components. It mainly uses a movable clamp sleeve between a fixed jaw and a movable jaw to adjust the opening size and clamp the steel pipe components. However, the movable clamp sleeve in the existing pipe clamps is moved by thread transmission, so when clamping larger or smaller components, it takes a long time to rotate the movable clamp sleeve to adjust the opening size of the pipe clamp, which leads to a relatively low working efficiency of the pipe clamp. Most of the existing pipe clamps use mechanical threads or racks to adjust the extension and retraction to achieve the fixing effect, and the operation is not convenient enough. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Summary of the invention
