[0008] Furthermore, the clamping device includes a fixed rod, on one side surface of the fixed rod, a plurality of movable sleeves are fixedly installed at equal intervals, and a spring is fixedly installed on one side of the interior of each of the movable sleeves. On the other side surface of the fixed rod, a plurality of L-shaped fixing plates are fixedly installed at both ends, and limit protrusions are fixedly installed on both sides of one end surface of each of the movable sleeves.

[0009] Furthermore, one end of each of the multiple springs is fixedly installed on one side inside the multiple movable holes.

[0010] Furthermore, the surfaces of the plurality of movable sleeves are correspondingly and movably embedded inside the movable holes, and the surfaces of the plurality of limiting protrusions are correspondingly and movably embedded inside the plurality of limiting movable grooves.

[0011] Furthermore, the support device includes two support rods and two U-shaped clamps. Multiple limiting grooves are equidistantly provided on the surfaces of the two support rods. Support rods are rotatably connected to the inner sides of one end of each of the two U-shaped clamps via a movable shaft. One end of each support rod is inserted into one of the multiple limiting grooves. The tops of the U-shaped clamps are fixedly installed on both sides of the bottom surface of the support plate. One end of each support rod is fixedly sleeved on the surface of the two rotating shafts. The four semi-circular clamps are arranged in pairs. The other ends of the two support rods are rotatably connected to the interior of the two sets of semi-circular clamps via movable shafts.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model addresses the issue that laptops, characterized by their thinness and portability, are becoming increasingly popular in modern life. However, the rotation angle and height of laptops are often limited, requiring a laptop stand for support. In this device, the user places the stand on a table and uses a sliding toothed plate to rotate a rotating rod. This rotation causes a ratchet to rotate, resulting in a ratchet wheel rotating in a fixed direction. When the user lifts the first support rod to a certain height, the ratchet mechanism prevents it from retracting under pressure in the opposite direction. Once the first support rod is lifted to a certain height, the second support rod can be inserted into a limiting groove to fine-tune the support height until a suitable height is achieved. This device, through its ratchet mechanism, solves the problem of support rod retraction and instability that often occurs with hydraulic or damping support rods after prolonged use.

[0016] 2. In this utility model, after the user adjusts to a suitable angle, pulling the fixing rods on both sides of the support plate will cause the movable sleeve to stretch outward. After the movable sleeve stretches outward, it will cause the spring to stretch outward. The limiting protrusion moves inside the limiting movable groove two, so that the movable sleeve will not disengage from the inside of the movable hole. The user places the computer on the surface of the support plate, with the bottom of the computer abutting against the inner surface of the L-shaped fixing plate two. When the fixing rod is released, the spring unloads and retracts, causing the L-shaped fixing plate one to lock the two sides of the computer. This clamping device clamps and fixes the laptop to the surface of the support plate, avoiding the problem of the laptop easily falling off after being accidentally bumped when placed directly on the support plate.

[0041] In one embodiment, the ratchet device 7 includes two ratchet wheels 701, which are fixedly mounted on one end of two rotating shafts 901. Pads 702 are engaged with the surfaces of both ratchet wheels 701. Rotating rods 703 are fixedly connected to the center of each of the two pawls 702.

[0042] Specifically, such as Figure 7 and 8 As shown: the rotation of the toothed plate 704 will drive the rotation of the rotating rod 703, the rotation of the rotating rod 703 will drive the rotation of the pawl 702, and the pawl 702 will limit the ratchet 701 to rotate in a fixed direction.

[0043] In one embodiment, the surface of the rotating circular plate 2 has two grooves 1 201 and two grooves 202. Both sides of the interior of the two grooves 1 201 have a limiting movable groove 204, which is located above the movable through hole 203. One side of the interior of the two grooves 1 201 has a movable through hole 203, and one end of the two movable through holes 203 is connected to one side of the interior of the two grooves 202.

[0044] Specifically, such as Figure 7 , 10 As shown in Figure 11: the first groove 201 provides a space for the toothed plate 704 to move, the movable through hole 203 provides a space for the rotating rod 703 to move, the second groove 202 provides a space for the ratchet 701 to move, the first limiting groove 204 provides a limiting for the toothed plate 704, and the toothed plate 704 slides inside the first groove 201 without disengaging from the first groove 201.

[0045] Working Principle: Laptops are increasingly popular in modern life due to their lightweight and portability. However, the rotation angle and height of laptops are usually limited, often requiring a laptop stand for support. During use, the user places the stand on a table, and the sliding toothed plate 704 drives the rotating rod 703 to rotate. The rotation of the rotating rod 703 drives the pawl 702 to rotate, causing the ratchet 701 to rotate in a fixed direction. When the user lifts the support rod 601 to a certain height, the ratchet mechanism prevents the support rod 601 from retracting under pressure in the opposite direction. When the support rod 601 is raised to a certain height, the support rod 603 can be inserted into the limiting groove 602 to fine-tune the support height until a suitable height is achieved. This device solves the problem of support rod retraction and instability caused by hydraulic or damping support rods after prolonged use.

[0046] After the user adjusts the angle to a suitable position, pulling the fixing rods 501 on both sides of the support plate 4 causes the movable sleeve 502 to stretch outward. After the movable sleeve 502 stretches outward, it will cause the spring 503 to stretch outward. The limiting protrusion 505 moves inside the limiting movable groove 402, so that the movable sleeve 502 will not come out of the movable hole 401. The user places the computer on the surface of the support plate 4, with the bottom of the computer against the inner surface of the L-shaped fixing plate 8. The user releases the fixing rods 501, and the spring 503 retracts to relieve the force, causing the L-shaped fixing plate 504 to lock the two sides of the computer. This device fixes the laptop computer on the surface of the support plate 4, avoiding the problem of it easily falling off when accidentally bumped, which was previously the case when the laptop was placed directly on the support plate.

[0047] After use, the user reverses the above steps, removes the computer, lifts the second support rod 603 so that its bottom is disengaged from the inside of the limiting groove 602, the toothed plate 704 slides in the opposite direction, causing the first support rod 601 to rotate in the opposite direction and lower the support rod to retract.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
