[0040] Referring to Figures 1-13The upper side of the base frame 17 is provided with a movable frame 18, which is hinged to the base frame 17 at one end close to the door plate 7. The movable frame 18 is in the shape of a right triangle in cross section. A second inclined surface 38 is formed on the bottom surface of the movable frame 18. A through hole 32 is formed in the inner wall of the storage chamber 9 at a position close to the opening end of the storage chamber 9. A rectangular box 19 is fixedly connected to the storage chamber 9 at the outer side of the through hole 32. A sliding block 31 for adjusting the inclination angle of the movable frame 18 is slidingly installed in the rectangular box 19. A first inclined surface 34 is formed on one side surface of the sliding block 31, which is matched with the second inclined surface 38. The sliding block 31 is slidingly installed in the through hole 32. A box cover 20 is installed on the side of the rectangular box 19 away from the storage chamber 9.

A partition ring 37 is arranged on the side of the disc 33 facing the handle 22, and the partition ring 37 is slidingly installed in the heat insulation cylinder 21. A sliding block 31 is in sliding contact with the inner wall of the rectangular box 19, so that the threaded rod 23 is screwed into the screw hole in the disc 33, and the disc 33 is installed in the heat insulation cylinder 21. When the threaded rod 23 is twisted, the threaded rod 23 drives the partition ring 37 to slide in the heat insulation cylinder 21. At this time, the connection part of the threaded rod 23 and the screw hole is in the closed space formed by the partition ring 37, the heat insulation cylinder 21, the sliding block 31 and the rectangular box 19, so as to prevent the connection part of the threaded rod 23 and the screw hole from being affected by the entry of sundries and affecting the twisting of the threaded rod 23.
