DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 The utility model provides a technical solution: a clamping and positioning drawing board with lifting function, comprising: a base 1, a limiting column 2, a lifting column 3, a connecting platform 4, a toothed plate 5, a lifting motor 6, a first bevel gear 7, a second bevel gear 8, a connecting rod 9, a circular gear 10, a drawing placement plate 11, a stepped groove 12, an elastic clamping rod 13, a connecting block 14, a supporting column 15, a threaded rod 16, a bottom plate 17 and an anti-slip pad 18;

[0029] When using the clamping and positioning drawing board with lifting function, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in the initial state, the painting placement board 11 is not supported by the support column 15. At this time, the painting placement board 11 is perpendicular to the ground. Before use, the height of the connecting platform 4 is adjusted according to the height of the user, and then the angle between the painting placement board 11 and the lifting column 3 is adjusted. First, the pin on the side of the limit column 2 is pulled out, and then the operation of lifting the painting board can be performed. Start the lifting motor 6, the lifting motor 6 will rotate with the first bevel gear 7, and the first bevel gear 7 will rotate with the connecting rod 9 through the second bevel gear 8. At this time, the connecting rod 9 will rotate with the circular gears 10 on both sides of the connecting rod 9. The connecting rod 9 is respectively connected to the fixed gears on the inner sides of the two limit columns 2. The fixed block is connected by rotation. During the lifting process, the connecting rod 9 will not deviate, ensuring the stability of the lifting. The rotation of the circular gear 10 will move the toothed plate 5 meshing with it in the longitudinal direction, so that the lifting column 3 will rise upward. At this time, the connecting platform 4 will rise with the lifting column 3. Circular gears 10 are provided on both sides of the connecting rod 9 to ensure that the connecting platform 4 always remains parallel to the base 1 during the lifting process. The side array of the lifting column 3 is provided with a socket, and the side of the limit column 2 is also provided with a socket. Then, the pin is inserted from the socket on the side of the limit column 2 into the socket on the side of the lifting column 3. After the lifting motor 6 is turned off, the connecting platform 4 will not fall.

[0030] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the painting placement board 11 is connected to the connecting platform 4 by hinges. In the initial state, the top of the support column 15 faces downward under the action of gravity. After adjusting the height, the painting placement board 11 is rotated and raised from the rear of the connecting platform 4. Since the support column 15 is rotatably connected to the connecting block 14, and the connecting block 14 is rotatably connected to the lifting column 3 by the fixing bolt, the top of the support column 15 faces upward. Then, the angle between the painting placement board 11 and the lifting column 3 is adjusted according to the needs of the painter, and the painting placement board 11 is loosened so that the top of the support column 15 is inserted into the step groove 12 on the lower side of the painting placement board 11. The step groove 12 is provided with a plurality of supporting points for the support column 15 to be inserted and fixed. Another support column 15 is inserted into the corresponding step groove 12 in the same way. At this time, the angle of the painting placement board 11 is adjusted.

[0031] like Figure 1 Hehe Figure 3As shown, the threaded rod 16 is threadedly connected to the base 1. The threaded rod 16 is rotated to move the bottom plate 17 below the threaded rod 16 downward. When the anti-slip pad 18 below the bottom plate 17 fits tightly against the ground, the threaded rod 16 is continued to be rotated until the threaded rod 16 cannot be rotated. At this time, the friction between the device and the ground is extremely large, and no deviation will occur during the creation process. Then, the elastic clamping rod 13 is rotated to place the drawing on the drawing placement board 11, and then the elastic clamping rod 13 is placed on the side of the drawing placement board 11. The drawing can be clamped to start creation.
