DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will further elaborate on this application with reference to the accompanying Figures 1-4 drawings.

[0034] An embodiment of this application discloses a dynamic handicraft. Referring to Figure 1 and Figure 2 , the dynamic handicraft includes a base 1, a first decoration unit 2 arranged on the base 1, a second decoration unit 3 arranged on the base 1 to move up and down, and a driving device 4 for driving the second decoration unit 3 to move up and down. There are multiple second decoration units 3, and the driving member is arranged inside the base 1, and the driving device 4 can drive all these second decoration units 3 to perform up-and-down undulating movements, thereby bringing a dynamic, more layered and variable visual effect.

[0035] Specifically, in this embodiment, the base 1 is in a shape with a hollow interior and an open bottom. The upper surface of the base 1 simulates a snowfield environment through structures such as foam. The first decoration unit 2 can be set as a fir tree, and the surface of the fir tree can also be dotted with snowflakes; the second decoration unit 3 can be set as an elk model and a Santa Claus model sitting on a sleigh. Through the driving device 4, a visual effect that the elk pulls Santa Claus flying continuously in the air and moving up and down can be created. At the same time, combined with the static first decoration unit 2, the combination of movement and stillness makes the handicraft more ornamental.

[0036] Referring to Figure 1 and Figure 2 , in this embodiment, a second support rod 31 is fixedly arranged on the lower surface of each second decoration unit 3. The lower end of the second support rod 31 slidably passes through the base 1 and is connected to the driving device 4. Thus, the second support rod 31 not only plays the role of driving the second decoration unit 3 to move up and down, but also enables the second decoration unit 3 to create an effect of flying in the air.

[0037] Referring to Figure 2 and Figure 3, in this embodiment, a first positioning plate 11 and a second positioning plate 12 are fixed on the bottom side wall of the base 1. Both the first positioning plate 11 and the second positioning plate 12 are arranged in the vertical direction. The driving device 4 includes a driving wheel 41, an eccentric shaft 42, a driving block 43, a transmission rod 44 and a power member 45. Among them, the driving wheel 41 is rotatably arranged on the second positioning plate 12, and the axis direction of the driving wheel 41 is perpendicular to the side wall of the second positioning plate 12; the eccentric shaft 42 is fixed on the side wall of the driving wheel 41 facing the first positioning plate 11, and the axis direction of the eccentric shaft 42 is offset from the axis direction of the driving wheel 41. The driving block 43 is slidably arranged up and down on the first positioning plate 11. A chute for the driving block 43 to slide up and down is provided on the side wall of the first positioning plate 11. The main body of the driving block 43 is a rectangular block. One end of the driving block 43 facing the second positioning plate 12 is set as a cylindrical section and extends out of the side wall of the first positioning plate 11. The two ends of the transmission rod 44 are respectively rotatably connected to the cylindrical end of the driving block 43 and the eccentric shaft 42. The end of the driving block 43 facing away from the second positioning plate 12 also extends out of the side wall of the first positioning plate 11 and is connected to the second support rod 31; the power member 45 can drive the driving wheel 41 to rotate.

[0038] During use, the power member 45 drives the driving wheel 41 to rotate, and drives the eccentric shaft 42 located on the driving wheel 41 to perform eccentric motion along with the driving wheel 41. This motion is transmitted to the driving block 43 through the transmission rod 44, so that the driving block 43 slides up and down in the chute on the first positioning plate 11, thereby driving the second support rod 31 and the second decoration unit 3 to move up and down.

[0039] Refer to Figure 2 and Figure 3, Further, in this embodiment, the driving device 4 further includes a central shaft 46. The power member 45 includes a worm gear 451, a worm 452, and a motor 453. Among them, the central shaft 46 is arranged between the driving wheel 41 and the second positioning plate 12. One end of the central shaft 46 is rotatably connected to the second positioning plate 12 by means of a bearing or the like, and the other end is fixedly connected to the side wall of the driving wheel 41. Thus, the driving wheel 41 can be rotatably connected to the second positioning plate 12 through the central shaft 46; the worm gear 451 is coaxially sleeved outside the central shaft 46, the worm 452 is fixed to the inner wall of the base 1 by means of a support or the like, and the worm 452 meshes with the worm gear 451; the motor 453 is preferably a micro motor 453, the motor 453 is fixed to the inner wall of the base 1 by means of bolts or the like, and the output end of the motor 453 is connected to the worm 452; thus, when the motor 453 is started, the worm 452 is driven to rotate, and the driving wheel 41 is driven to rotate through the transmission of the worm gear 451, and finally the second support rod 31 is driven to move up and down. It should be noted that, in this embodiment, a plurality of groups of driving blocks 43, transmission rods 44, driving wheels 41, central shafts 46, and worm gears 451 are respectively arranged corresponding to the support rods. One worm 452 is arranged and meshes with all the worm gears 451. Thus, all the worm gears 451 can be driven to rotate by the worm 452, and all the support rods can be driven to move up and down; in order to achieve the up-and-down undulating effect, at the same time, the height positions of each support rod are different.

[0040] Refer to Figure 2 and Figure 3 , in another alternative embodiment, further, in order to ensure the stability of the driving block 43 when sliding up and down, a guiding block 431 is fixed on the side wall of the driving block 43. The guiding block 431 can be a rectangular block. A guiding groove for the guiding block 431 to slide up and down is opened on the first positioning plate 11, and the guiding groove is communicated with the sliding groove. This design can ensure that the driving block 43 always maintains a stable posture during the up-and-down sliding process, and avoid affecting the smoothness and reliability of the dynamic effect due to deviation or inclination.

[0041] Refer to Figure 2 and Figure 3 , in another alternative embodiment, an insertion block 32 is fixed to the lower end of the second support rod 31. The insertion block 32 can be a rectangular block. A slot for the insertion block 32 to be inserted is opened on the upper surface of the driving block 43. Through a simple insertion operation, the second support rod 31 can be quickly connected to the driving block 43; at the same time, in order to ensure the stability and safety of the connection, a limiting member 5 for restricting the insertion block 32 from disengaging from the slot is further provided on the driving block 43. The limiting member 5 specifically adopts a combination form of a limiting bolt and a limiting nut. The limiting bolt can sequentially pass through the driving block 43 and the insertion block 32 and form a tight threaded connection with the limiting nut; this connection method not only has sufficient strength to withstand the force generated when the second support rod 31 moves up and down, but also is convenient for disassembly and maintenance when needed.

[0042] Referring to Figure 1 and Figure 4 , in this embodiment, a first support rod 21 is provided at the lower end of the first decoration unit 2, and an elastic ring 22 is coaxially provided at the lower end of the first support rod 21. The elastic ring 22 can be made of rubber. Accordingly, a slot for inserting the first support rod 21 and a connection groove for clamping the elastic ring 22 are formed on the upper surface of the base 1. Through the interference fit between the elastic ring 22 and the connection groove, a stable connection between the first decoration unit 2 and the base 1 is achieved. This connection method is convenient and fast, facilitating the fixing or adjustment of the position and layout of the first decoration unit 2.

[0043] Referring to Figure 1 and Figure 4 , further optionally, light belts 6 can be wound around all the first decoration units 2 and all the second decoration units 3 to enhance the atmosphere of the handicraft.

[0044] The implementation principle of a dynamic handicraft in an embodiment of the present application is as follows: Through the cooperation of the elastic ring 22 and the connection groove, the first decoration unit 2 can be quickly fixed on the base 1. Then, through the cooperation of the limit bolt and the limit nut, the second decoration units 3 are fixedly connected to the driving blocks 43 one by one. Then, when the motor 453 is started, all the second decoration units 3 can be driven to move up and down, thus forming an ornamental effect with a combination of movement and stillness and rich variability.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
