[0017] The following is combined Figure 1-4 This invention describes a specific embodiment of an external cylindrical grinding rod clamping mechanism, which includes a support frame 1 for supporting mechanism components. The support frame 1 is provided with a clamping adjustment assembly and a replaceable head clamping assembly. The clamping and adjusting assembly includes: a guide rod 2, a guide hole 3, a clamping frame 4, a first threaded hole 5, a first threaded rod 6, a lifting bracket 7, a slider 8, a slide rail 9, an adjusting hole 10, a bolt hole 11, and an adjusting bolt 12. The guide hole 3 is formed on the clamping frame 4, the guide rod 2 is mounted on the support frame 1 and passes through the guide hole 3, the first threaded hole 5 is formed on the clamping frame 4, the first threaded rod 6 is mounted on the support frame 1 and passes through the first threaded hole 5, the bolt hole 11 is formed on the clamping frame 4, the slider 8 is mounted on the lifting bracket 7, the slide rail 9 is formed on the clamping frame 4, the lifting bracket 7 is mounted on the slide rail 9 via the slider 8, the adjusting hole 10 is formed on the lifting bracket 7, and the adjusting bolt 12 passes through the adjusting hole 10 and is mounted on the bolt hole 11.

[0018] It should be noted that before clamping, the first threaded rod 6 is rotated to start rotating in the first threaded hole 5, so that the clamping frame 4 can be moved and adjusted on the guide rod 2, thereby adjusting according to the length of the rod. The lifting bracket 7 can be adjusted to a suitable height through the adjustment hole 10. Then, the adjustment bolt 12 is tightened to fix the position of the lifting bracket 7, thus completing the clamping adjustment.
