This detachable connection method provides convenience for folding and storing the easel, further reducing the size of the easel, making it easy to carry and transfer, and greatly improving the flexibility and convenience of using the easel.

[0029] Example 2

[0030] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0031] As a preferred embodiment, on the front side of the fixing plate 4, with the center line of the fixing plate 4 as a reference, symmetrical limit grooves 5 are opened on both sides. The two limit grooves 5 not only correspond to each other in position, but also have the same size and shape. The symmetrically opened limit grooves 5 can ensure that the components subsequently installed on them maintain balance and stability during movement, and avoid equipment malfunction or failure due to position deviation, thus providing an important guarantee for the stable operation of the entire device.

[0032] In a preferred embodiment, a compression spring 7 is fitted on the outer side of the slide rod 6. The compression spring 7 is tightly fitted against the slide sleeve 8. The compression spring 7 is made of a high-elasticity metal material and has good resilience. The inner diameter of the compression spring 7 is closely matched with the outer diameter of the slide rod 6, so that it can be stably fitted on the slide rod 6. One end of the compression spring 7 is tightly fitted to the positioning structure preset in the limiting groove 5, and the other end of the compression spring 7 is tightly fitted to one side of the slide sleeve 8. When the slide sleeve 8 slides on the slide rod 6, the compression spring 7 will be compressed or stretched, thereby generating a corresponding elastic force, providing a buffer and reset function for the movement of the slide sleeve 8.

[0033] In a preferred embodiment, a support plate 11 is fixedly installed on the front side of the fixing plate 4 by welding and fastening with bolts. The support plate 11 is made of high-strength, deformation-resistant metal material, and its edges are rounded to avoid scratching the items. Anti-slip strips 12 are evenly and tightly fixedly pasted on the inner wall of the support plate 11. The anti-slip strips 12 are made of high-quality rubber and have fine raised textures on the surface, which can significantly increase the friction between the anti-slip strips and the placed items, effectively preventing the items from sliding and shifting on the support plate 11.

[0034] In a preferred embodiment, a bearing 15 is securely installed at the end of the threaded rod 14 near the limiting frame 13. The bearing 15 is a high-precision, wear-resistant, and high-quality model. The outer ring of the bearing 15 is tightly and firmly connected to the inner wall of the limiting frame 13 by welding, ensuring that there is no looseness at the connection. When the threaded rod 14 is rotated by an external force, this end of the threaded rod 14 will rotate stably on the inner wall of the bearing 15. The bearing 15 effectively reduces the frictional resistance during the rotation process, ensuring that the threaded rod 14 can rotate flexibly and smoothly, thereby ensuring the high efficiency and reliability of the entire device.

[0035] In a preferred embodiment, a positioning seat 21 is reinforced and installed on the rear side of the fixed plate 4 by welding. The positioning seat 21 is made of stainless steel, which is sturdy and corrosion-resistant. Its interior is finely polished and has a smooth and flat surface, which can provide stable support and precise positioning for subsequent components. The end of the movable rod 20 away from the first connecting sleeve 18 is fixedly installed with a second connecting sleeve 22 by welding. The weld is full and firm. The size of the second connecting sleeve 22 is adapted to the internal space of the positioning seat 21. The second connecting sleeve 22 is located inside the positioning seat 21 and can move and be positioned to a certain extent within the positioning seat 21.

[0036] In a preferred embodiment, a placement slot 23 is cut into the side of the rack 1 facing the operator. The placement slot 23 is a regular cuboid shape with smooth, burr-free edges. Its depth and width are carefully designed to meet the needs of tool storage. A tool drawer 24 is slidably installed inside the placement slot 23. Smooth rollers are installed on both sides of the drawer for easy pushing and pulling. The tool drawer 24 has a partition fixed inside using a welding process. The partition divides the interior of the tool drawer 24 into multiple independent spaces, which facilitates the classification and storage of tools of different types and specifications, making them easy to access and manage.

[0037] In a preferred embodiment, the threaded rod 14 passes through the limiting frame 13 and the holding rack 1 in sequence. The limiting frame 13 has a through hole that is compatible with the threaded rod 14, and the inner wall of the through hole is finely polished to ensure that the threaded rod 14 can pass through smoothly. The holding rack 1 also has a hole at the corresponding position. The threaded rod 14 extends to the outside of the holding rack 1. A rotating disk 25 is fixedly installed at the end of the threaded rod 14 that extends to the outside of the holding rack 1 by a strong welding method. The surface of the rotating disk 25 has anti-slip texture, which makes it convenient for the operator to rotate it manually, thereby driving the threaded rod 14 to rotate.

[0038] The working process of this utility model is as follows: In use, firstly, according to actual needs, push the sleeve rod 3 to slide outside the adjusting rod 2 to adjust the height of the fixing plate 4. After determining the appropriate height, the position of the sleeve rod 3 can be further fixed by bolts or other means. Then, place the bottom of the drawing board above the bearing plate 11, and the bottom surface of the drawing board is in close contact with the anti-slip strip 12. The anti-slip strip 12 can prevent the item from sliding. At the same time, the top of the drawing board is in contact with the inner wall of the clamping plate 10. According to the size of the drawing board, the sliding sleeve 8 can slide freely along the sliding rod 6. The position of the clamping plate 10 is adjusted by sliding the sliding sleeve 8 so that the clamping plate 10 is in a suitable position to clamp the drawing board. The compression spring 7 on the outside of the sliding rod 6 plays a buffering and resetting role during the sliding of the sliding sleeve 8, thus completing the adjustment of the position of the clamping plate 10.

[0039] Next, when the tilt of the drawing board needs to be adjusted, the rotating disk 25 installed at one end of the threaded rod 14 is rotated, causing the threaded rod 14 to rotate within the limiting frame 13. Since the outer threaded sleeve of the threaded rod 14 is fitted with an inner threaded sleeve 16, when the threaded rod 14 rotates, the inner threaded sleeve 16 will move along the threaded rod 14, thereby driving the bearing seat 17 to move, thus adjusting the position of the first connecting sleeve 18, the movable rod 20, and other related components. The first connecting sleeve 18 at the lower end of the movable rod 20 is inserted into the bearing seat 17 and positioned using the positioning pin 19. The position of the movable rod 20 is fixed. At the same time, the end of the movable rod 20 away from the first connecting sleeve 18 is fixedly installed with the second connecting sleeve 22 by welding. The second connecting sleeve 22 is located inside the positioning seat 21 welded and reinforced on the rear side of the fixed plate 4, which plays a role in further positioning and stabilizing the movable rod 20. Finally, the tool drawer 24 is slid out from the placement slot 23 on the side of the shelf 1 facing the operator. The tool drawer 24 has a partition fixedly installed inside by welding process, which can classify and store different tools in the space separated by the partition for easy access.
