The position of the fixing device can be kept stable by arranging the magnetic ring 23, the steel ring 12 and other parts, so that the section of the hose 24 can be flat, and the cutting quality of the hose 24 can be improved.
Through setting up fixing device, can support fixedly to the hose 24 inner wall to increase the interact power between cutter 5 and the hose 24, with the assurance can effectually cut off hose 24.
The annular air bag 13 is sleeved outside the steel ring 12, through holes are formed in the side walls of the limiting seat 3 and the support frame 1, the two magnetic rings 23 are embedded in the two through holes respectively, the first telescopic pipe 14 and the second telescopic pipe 15 are welded with the two steel rings 12, the first telescopic pipe 14 and the second telescopic pipe 15 are communicated with the two annular air bags 13, the limiting seat 3 is arranged on the side wall of the rotary cutting ring 2, and the limiting seat 3 is rotatably connected with the rotary cutting ring 2. It should be noted that, by arranging the first extension tube 14 and the second extension tube 15 with adjustable lengths, when the hose 24 passes through the limiting seat 3, the rotary cutting ring 2 and the support frame 1, the passing length of the hose 24 can be adjusted by adjusting the lengths of the first extension tube 14 and the second extension tube 15, so that the hoses 24 with different lengths can be cut. And the first extension tube 14 and the second extension tube 15 are rigid tubes made of hard materials, so that the horizontal heights of the two steel rings 12 can be kept unchanged.
Further, the average diameter of the first extension tube 14 is larger than that of the second extension tube 15, so that the air output of the first extension tube 14 is larger than that of the second extension tube 15 under the condition that the air output of the first air outlet tube 17 is sufficient, and the two annular air bags 13 can be inflated.
