[0002] In daily production, columnar parts are one of the most common parts. During their processing, they often need to be clamped to assist processing, and clamping tools are a commonly used device in the preparation of columnar parts. However, in actual use, the existing clamping tools for columnar parts generally directly design a fixed V-shaped bracket to limit the clamping of columnar parts, or use the upper and lower sides to achieve clamping. These methods either have low adjustment performance and are difficult to adjust according to the diameter of the parts, or have poor stability and are easy to slip. Utility Model Content

The clamping assembly 3 also includes an upper clamping plate 304, and the upper clamping plate 304 is fixed on the right side of the rotating frame 303. The upper clamping plate 304 and the lower clamping plate 302 form a V-shaped structure. The V-shaped structure is formed by the upper clamping plate 304 and the lower clamping plate 302.
