[0027] The bottom of the feed tube 8 is arc-shaped and has an opening. The upper half of the adjustment tube 810 is hemispherical and the lower half is tubular. The outer wall of the hemispherical part of the adjustment tube 810 fits the arc-shaped inner wall of the feed tube 8, so that the upper end of the adjustment tube 810 can swing at a certain angle inside the arc-shaped inner wall of the feed tube 8, and the upper end surface of the hemispherical part of the adjustment tube 810 is set as an inclined surface. The setting of the inclined surface can make the repair material inside the feed tube 8 smoothly enter the inside of the adjustment tube 810. A plurality of fixed fixing rods are arranged at equal angles on the outer wall of the feed tube 8. 801, a rotating rod 803 is hinged at the bottom end of the fixed rod 801, and a roller 804 is rotatably connected to the other end of the rotating rod 803, and the roller 804 abuts against the outer wall of the adjustment tube 810.

A plurality of stirring blades 21 are fixedly connected to the side wall of the rotating drum 24, and the stirring blades 21 are composed of two stirring plates, and the two stirring plates are inclined and arranged with a "V" shape in cross section. The arrangement of the heating plate 15 and the heating wire 18 can heat the repair material to avoid a decrease in the fluidity of the repair material. Further, the rotation of the stirring blade 21 is also to stir the repair material to prevent it from solidifying. At the same time, when the stirring plate rotates, due to the "V" shape in cross section, on the one hand, the rotation resistance can be reduced, and on the other hand, the repair material in the middle position of the barrel 3 can be moved toward the inner wall of the barrel 3, thereby improving the heating uniformity of the repair material and improving its fluidity.

[0031] A gear 25 is rotatably fixedly connected to the inner top wall of the rotating drum 24, and a connecting plate 28 is provided below the gear 1 25.
