[0027] The anti-detachment component 9 includes a slot 901, which is located inside the body 1 and is distributed one-to-one with the two ends of the rotating shaft 7. The anti-detachment component 9 also includes a first telescopic spring 902, a locking plate 903, and a limiting groove 904. The locking plate 903 is connected to the body 1 through the first telescopic spring 902 and is distributed vertically with the end of the rotating shaft 7. The locking plate 903 has limiting grooves 904 at both ends. The anti-detachment component 9 also includes a fixing plate 905, a second telescopic spring 906, and a limiting rod 907. The fixing plate 905 is fixedly installed on the outside of the body 1 and is connected to the limiting rod 907 through the second telescopic spring 906. The limiting rod 907 passes through the inside of the fixing plate 905 and its tail end engages with the limiting groove 904.

[0028] When assembling the roller body 8 into the inner side of the machine body 1, this structure first places both ends of the rotating shaft 7 inside the corresponding slots 901. Then, pull the limiting rod 907 outward and manually press the clamping plate 903 downward, so that the notch on the inner side of the clamping plate 903 engages with the upper end of the rotating shaft 7, thereby fixing the end of the rotating shaft 7. After the position of the clamping plate 903 is adjusted, release the limiting rod 907.
