[0035] Working principle: When it is necessary to fix the pipe fitting, the clamping block 61 can be pressed inward to move it inward first. When the fixing component 6 is detached from the inner wall of the lower clamping block 4, the upper clamping block 5 can be moved upward to remove the pipe fitting, and then the pipe fitting can be placed on the top of the lower clamping block 4, and the upper clamping block 5 can be inserted back to the top of the lower clamping block 4 according to the original path, and then the clamping block 61 can be released, and the fixing spring 64 will push the clamping block 61 outward to make it re-engage in the inner wall of the lower clamping block 4, and the lower clamping block 4 and the upper clamping block 5 will be re-fixed, and then the pressing block 72 can be pressed downward, and the pressing block 72 will drive the reinforcement block 76 to move downward synchronously to squeeze the outer wall of the pipe fitting, and the pipe fitting will be completely fixed.

[0036] When it is necessary to replace the lower clamping block 4 of a different size, the slider 33 can be directly pushed upwards. The slider 33 will move upwards and drive the connecting rod 34 to rotate upwards. The connecting rod 34 will push the connecting block 35 to move it outwards and disengage from the slot 32. At this time, the lower clamping block 4 can be directly removed and the newly replaced lower clamping block 4 can be inserted back to the top of the support frame 2 along the original path. Then the slider 33 can be released, and the connecting spring 36 will push the connecting block 35 inwards to move it inwards and re-fix the insertion block 31.
