The clamping plate 3 is arranged, the clamping plate 3 is sleeved on the pull rod 4 and is positioned between the lifting handle 5 and the other end of the shell 2, and a clamping space 7 for clamping a thin plate is arranged between the clamping plate 3 and the other end of the shell 2; when the novel solar energy collection device is used, the thin plates such as the sun shield can be clamped in the clamping space 7, the adsorption disc 1 of the suction disc is adsorbed on the surface of an automobile or other smooth objects, the thin plates such as the sun shield can be fixed on the covered object, the thin plates are prevented from leaving the covered object due to external factors such as wind, and the novel solar energy collection device is simple and convenient to use and firm in fixation.

The adsorption disc 1 is made of elastic materials, and has certain elastic deformation capacity, such as nitrile rubber, natural rubber, synthetic rubber and the like.

The suction plate 1 has a concave shape recessed in a direction away from the suction surface, which is advantageous for suction of the suction plate 1 on the suction surface. The adsorption surface is the surface of the object adsorbed by the sucker.

When the adsorption plate is used, the adsorption plate 1 is contacted with the adsorption surface and attached, and then the pull rod 4 is lifted in the direction away from the adsorption surface, so that the center of the adsorption plate 1 is pulled in the direction away from the adsorption surface, the edge of the adsorption plate 1 moves in the center direction on the adsorption surface, an air cavity is formed between the adsorption plate 1 and the adsorption surface, the air pressure in the air cavity is smaller than the external atmospheric pressure, and the adsorption plate 1 is tightly adsorbed on the adsorption surface under the action of the pressure difference between the inside and outside of the air cavity, so that the fixation of a sucking disc and an object to be sucked is realized.

In order to facilitate the pulling of the pull rod 4, the pulling handle 5 is rotatably connected with the other end of the pull rod 4 and can rotate between a first position and a second position to pull or reset the pull rod 4 away from the adsorption disc 1, wherein an included angle between the first position and the second position is 90 degrees. The first position is in the axial direction of the pull rod 4.

Normally, the lifting handle 5 is positioned at the second position; when the adsorption device is used, the adsorption disc 1 is attached to the adsorption surface, the lifting handle 5 is rotated to the first position, and the pull rod 4 is pulled up in the direction away from the adsorption surface, so that the adsorption disc 1 is adsorbed on the adsorption surface; when the sucker needs to be taken down, the lifting handle 5 is rotated to a two-position.

Specifically, the handle 5 includes a handle portion 51 and a connecting portion 52 fixed to the handle portion 51, and the other end of the pull rod 4 is rotatably connected to the handle portion 51 via a rotation shaft 6.

The handle portion 51 has a C-shaped structure, and the connecting portions 52 are provided at both ends of the opening of the C-shaped handle portion 51, and the connecting portions 52 may be integrally formed with the handle portion 51 or may be formed separately. A through hole through which the rotation shaft 6 passes is provided at the other end of the pull rod 4, the rotation shaft 6 passes through the through hole, and both ends thereof are respectively rotatably connected with the connection parts 52 of the corresponding ends.

The end, far away from the handle part 51, of the connecting part 52 is a pressing end 53, and the distance between the center of the rotating shaft 6 and the pressing end 53 is greater than the distance between the center of the rotating shaft 6 and the top of the clamping plate 3; the end surface of the pressing end 53 and the adjacent surface of the connecting part 52 are in arc transition, so that the rotation is facilitated.

When the lifting handle 5 is positioned at the second position, the end surface of the pressing end 53 is perpendicular to the top of the clamping plate 3; when the lifting handle 5 rotates to the first position, the end face of the pressing end 53 gradually rotates towards the top of the clamping plate 3 and presses against the clamping plate 3, so that the pull rod 4 rotatably installed on the connecting part 52 is driven to pull up towards the direction away from the adsorption disc 1, and the adsorption function of the sucker is realized.

The clamping plate 3 is a plate-shaped member, and the clamping plate 3 is provided with a connecting hole penetrating through both sides thereof to be connected with the pull rod 4, and the aperture of the connecting hole is larger than the outer diameter of the pull rod 4. The other end of the pull rod 4 passes through the top of the housing 2 and the connecting hole and then is connected with the lifting handle 5, and the clamping plate 3 can move upwards along the axial direction of the pull rod 4.

When the pulling handle 5 rotates from the second position to the first position, the pressing end 53 presses on the clamping plate 3, so that the clamping plate 3 moves towards the housing 2, and when the pulling handle 5 rotates back to the second position, the clamping plate 3 can be released.

After the thin plate is clamped in the clamping space 7 between the clamping plate 3 and the shell 2, when the lifting handle 5 rotates to the first position to enable the sucker to be in an adsorption state, the pressing action of the pressing end 53 on the clamping plate 3 also enables the thin plate to be clamped between the clamping plate 3 and the shell 2 more firmly.

When in use, the edge of the thin plate can be clamped in the clamping space 7, or a clamping hole with the aperture smaller than the size of the clamping plate 3 can be formed in the thin plate, and the thin plate is sleeved on the pull rod 4 through the clamping hole and is positioned between the clamping plate 3 and the shell 2.
