The longitudinal rod 11 and the limit block 14 are slidably connected to a cross limit slot 15 provided on the housing 1 , and the limit block 14 is also connected to an elastic member 2 16 arranged in the cross limit slot 15 .

[0020] In one embodiment of the present invention, when installing the toy body 9, the handle 13 is pulled outward, and the handle 13 pulls the longitudinal rod 11, the grinding sheet 12 and the limit block 14 to slide along the casing 1, and the elastic member 16 is deformed under the force to ensure that the end of the grinding sheet 12 is completely in contact with the side of the toy body 9, and the surface of the toy body 9 is polished when the toy body 9 is in a rotating state.

[0021] like Figure 1 , Figure 4 and Figure 5As shown, as another preferred embodiment of the present invention, the adaptive adjustment mechanism 300 includes a driving screw 23, a movable block 25, a limit frame 26, a guide rod 27, an elastic member 28 and a polishing head 29; The driving screw 23 is rotatably mounted on the housing 1, a movable block 25 is mounted on the driving screw 23, a limit frame 26 is mounted on the side of the movable block 25, and the limit frame 26 is slidably connected to the housing 1; The guide rod 27 is slidably mounted on the movable block 25 and is arranged offset from the driving screw 23. A polishing head 29 is rotatably mounted on the end of the guide rod 27 and abuts against the toy body 9. A baffle is arranged on the side of the guide rod 27, and an elastic member 28 is arranged between the baffle and the movable block 25 for automatically adjusting the position of the polishing head 29 in the horizontal direction.

[0022] In one embodiment of the present invention, the driving screw 23 pushes the movable block 25 and the limit frame 26 to slide in the height direction along the casing 1 when rotating, and the guide rod 27 and the polishing head 29 rise and fall synchronously accordingly, and when the diameter of the toy changes, the polishing head 29 and the guide rod 27 are pushed to slide along the movable block 25, and the elastic member 3 28 is deformed by the force to keep the polishing head 29 always in contact with the toy body 9.

[0023] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the synchronous drive mechanism 400 includes a support rod 30, a horizontal shaft 31, a driving gear 32, a movable gear 33, a limiting ring 34 and an inclined rod 35; The support rod 30 is fixedly mounted on the surface of the guide rod 27, and a horizontal shaft 31 is rotatably mounted on the support rod 30. A driving gear 32 is mounted on one end of the horizontal shaft 31, and the driving gear 32 is meshed with a driven gear arranged on the polishing head 29; A movable gear 33 is installed at the other end of the horizontal shaft 31, and a keyway provided on the horizontal shaft 31 is slidably connected to the middle of the movable gear 33; The limiting ring 34 is rotatably mounted on the side of the movable gear 33 , and the limiting ring 34 is fixedly connected to an inclined rod 35 installed at the end of the limiting frame 26 , so as to serve as a rotating support.

[0024] In one example of the present invention, when the polishing head 29 moves along the surface of the toy body 9, the movable gear 33 is meshed with the toothed plate installed in the housing 1, which can drive the movable gear 33 to rotate along the limit ring 34. The movable gear 33 drives the horizontal axis 31 and the driving gear 32 to rotate synchronously. The driving gear 32 drives the driven gear and the polishing head 29 to rotate along the guide rod 27, and the arranged polishing head 29 polishes the places that the grinding sheet 12 cannot reach; in addition, when the polishing head 29 is subjected to horizontal force, the horizontal axis 31 on the guide rod 27 slides along the movable gear 33 to ensure that the polishing head 29 is in a rotating state.

[0025] like Figure 1 and Figure 6 As shown, as another preferred embodiment of the present invention, the engagement transmission mechanism 500 includes a toggle frame 17, a movable frame 18, a movable plate 19, a driving plate 20, an arc plate 21, a straight tooth portion 22, an engagement wheel 24 and a bottom frame 36; The bottom frame 36 is fixedly mounted at the bottom of the housing 1, and a movable frame 18 is slidably mounted in the bottom frame 36. The movable frame 18 is composed of a frame body and a cross bar. A spur tooth portion 22 is provided on the side of the cross bar. The spur tooth portion 22 meshes with a connecting wheel 24 installed at the bottom of the driving screw 23. A movable plate 19 is slidably mounted on the inner side of the movable frame 18, and a driving plate 20 and an arc plate 21 are mounted on the movable plate 19. The column on the driving plate 20 is connected to the toggle frame 17 mounted on the bottom of the bottom shaft 2, and is used to push the movable frame 18 to move when the bottom shaft 2 rotates.

[0026] In one embodiment of the present invention, the bottom shaft 2 drives the toggle frame 17 at the bottom end to rotate synchronously when rotating, the toggle frame 17 drives the driving plate 20 to move, the movable plate 19 pushes the movable frame 18 to slide along the bottom frame 36, and the spur gear portion 22 pushes the connecting wheel 24 and the driving screw 23 to rotate when moving with the movable frame 18. When the toggle frame 17 passes through the arc plate 21, the movable plate 19 can slide along the movable frame 18 to achieve reversal, so that the movable frame 18 can move in the opposite direction along the bottom frame 36. The above process is repeated in this way, and the rotation direction of the driving screw 23 can be periodically adjusted when the bottom shaft 2 rotates continuously to ensure that the polishing head 29 can cover the outer side of the toy body 9.

[0027] In summary, the handle 13 is pulled outward, so that the longitudinal rod 11 and the grinding sheet 12 slide along the casing 1, and the toy body 9 is placed on the tray 4. Under the elastic force of the elastic member 6, the tray 4, the top shaft 7 and the fixed claw 8 are arranged to fix the toy body 9. When the driving motor 10 is working, the toy body 9, the tray 4, the vertical shaft 3 and the bottom shaft 2 are driven to rotate synchronously. When the toy body 9 is in a rotating state, it fits with the end of the grinding sheet 12 so that the grinding sheet 12 can polish the surface of the toy body 9. At the same time, the bottom shaft 2 also drives the toggle frame 17 at the bottom to rotate, and the toggle frame 17 toggle the drive plate 20 to move, and the movable plate 19 pushes the movable frame 18 to slide along the bottom frame 36. The spur tooth portion 22 pushes the connecting wheel 24 and the driving screw 23 to rotate when it moves with the movable frame 18. When the driving screw 23 rotates, it pushes the movable block 25 and the limit frame 26 to rotate along the casing 1 in height. When the toy body 10 is moved to the movable block 25, the guide rod 27 and the polishing head 29 are lifted and lowered synchronously. When the diameter of the toy changes, the polishing head 29 and the guide rod 27 are pushed to slide along the movable block 25. Since the movable gear 33 is meshed with the toothed plate installed in the housing 1, the movable gear 33 can be driven to rotate along the limit ring 34. The movable gear 33 drives the horizontal shaft 31 and the driving gear 32 to rotate synchronously. The driving gear 32 drives the driven gear and the polishing head 29 to rotate along the guide rod 27. The arranged polishing head 29 polishes the places that the polishing sheet 12 cannot reach. The polishing sheet 12 in the polishing machine fits tightly to the surface of the toy body 9, and can perform a large-scale polishing on the surface of the toy body 9 when the toy body 9 rotates. The floating polishing head 29 is used to perform fine polishing on the places that the polishing sheet 12 cannot reach, which can not only effectively improve the polishing efficiency, but also avoid the existence of polishing dead angles on the side of the toy, thereby ensuring the comprehensiveness and quality of the polishing.
