[0029] Refer to the attached Figures 1 to 4 An adjustable inner groove thinning device comprises a clamping mechanism 1, which is used to fix a plurality of round tubes 2 at equal distances. A transverse movement mechanism 3 is arranged on one side of the clamping mechanism 1, and a thinning mechanism 4 and a grinding mechanism 5 are arranged on the output end of the transverse movement mechanism 3. The transverse movement mechanism 3 drives the thinning mechanism 4 and the grinding mechanism 5 to move laterally. The thinning mechanism 4 is used to cut the inner groove of the end of the round tube 2, and the grinding mechanism 5 is used to grind the inner groove. The transverse movement mechanism 3 is fixed on the upper end of the lifting platform 6.

[0030] The clamping mechanism 1 includes a support frame 11, two fixed blocks 12 are arranged in parallel on the upper end of the support frame 11, and a clamping block 13 is arranged on each fixed block 12. A plurality of clamping grooves 14 are opened on the adjacent surfaces of the fixed block 12 and the clamping block 13. The clamping groove 14 is a semicircular groove, and the diameter of the semicircular groove is the same as the outer diameter of the circular tube 2. Connecting ears 15 are arranged at both ends of the fixed block 12 and the clamping block 13, and the connecting ears 15 are connected by a bolt assembly 16.
