The support frame 11 is columnar and the bottom of the support frame 11 is not fixedly connected to the base 21, so that the movement of the support frame 11 can be realized. A sliding rail 7 is provided on the bottom platform 1, and a gv trolley 8 is symmetrically arranged on the sliding rail 7. A pull-out plate 9 is arranged on the upper end of the gv trolley 8. The gv trolley 8 drives the support frame 11 to move through the pull-out plate 9. The pull-out plate 9 is driven by the gv trolley 8 to move, and the pull-out plate 9 goes deep into the support frame 11. The bottom is then driven by the gv trolley 8 to move the pull-out plate 9, and the pull-out plate 9 then pulls out the supporting frame 11, which is flexible and convenient and improves safety. The pull-out plate 9 is in an inverted L shape, which further increases the contact area with the bottom of the supporting frame 11 and improves stability during pulling out and putting in. A handle 16 and a discharge pipe 15 are provided on one side of the carrying box 14. The carrying box 14 can be pulled out by the handle 16, which is convenient for cleaning the carrying box 14, and the wax oil inside the carrying box 14 can also be discharged through the discharge pipe 15, which is flexible and convenient.
