Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to a grabbing component. Background Art

[0002] The internal support clamp is a device used to clamp pipe materials. It supports the inner wall of the pipe material through a top block to achieve the clamping function. It is more stable than the external clamp and will not damage the surface of the pipe material. In the prior art, the internal support clamp realizes the retraction and extension of the top block through a built-in gear mechanism. Although the accuracy is good, its parts structure is complex and the cost is high. Some internal support clamps drive the top block to rotate around the axis through a telescopic mechanism to provide support, but the pressure of the pipe wall is concentrated on the connecting shaft, which can easily cause the connecting shaft to wear and deform.
