When the return spring 92 is in a normal state, the slider 911 abuts against the guide rod 95 around which the two pull cords 91 are wound.

Referring to fig. 9 and 10, when the push block 93 is turned into the slide groove 424, the push block 93 passes through the guide rod 95 abutting against the slider 911, and the push block 93 can push the slider 911 to slide along the slide groove 424, and the push block 93 pulls the pull rope 91, so that the pull rope 91 rotates with the sleeve 8. When the push block 93 rotates about the rotation center of the rotating lever 61 until the projection 81 abuts against the end of the guide groove 423, the push block 93 rotates away from the slider 911, so that the return spring 92 can drive the sleeve 8 to rotate. When the scraping strip 631 picks up the first residual material strip 20, the sleeve 8 is in a rotating state, and when the scraping strip 631 picks up the second residual material strip 20, the pushing block 93 leaves the sliding block 911, and the dried peach is in a rotating state.
