[0023] Figure 2 This is a cross-sectional view of the clamping device of the present invention;

[0024] Figure 3 This is a cross-sectional structural diagram of the screen fan of the present invention. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 , 2 According to embodiment 3, the present invention provides a clamping device for a screen fan, including a clamping housing 1 for connecting to the fan, a clamping plate 2, and an opening and closing mechanism 3 for controlling the opening and closing between the clamping plate 2 and the clamping housing 1.

[0027] The opening and closing mechanism 3 includes an elastic component for maintaining the clamping tendency between the clamping housing 1 and the clamping plate 2, a pry plate 31 for pushing out the clamping plate 2, and an opening and closing button 32 for pressing down one end of the pry plate 31. The pry plate 31 is provided on both sides of the opening and closing button 32, and a button 33 is provided for synchronously contacting each pry plate 31.

[0028] The middle part of the pry bar 31 is hinged to the clamping housing 1. One end of the pry bar 31 is in contact with the clamping plate 2, and the other end is in contact with the pressing plate 33.

[0029] Specifically, to better accommodate the clamping of the display screen, the clamping housing 1 is provided with a back plate 11 corresponding to the clamping plate 2. The clamping plate 2 is pressed against the back plate 11 by an elastic component to clamp and fix the object more closely. The elastic component includes a reset rod 34 and a reset spring 35 connected to the clamping plate 2. The clamping housing 1 is provided with a sliding rod hole 12 through which the reset rod 34 passes to connect with the clamping plate 2. The reset spring 35 is sleeved on the reset rod 34. One end of the reset rod 34 is provided with a pressure plate 36 for contacting and compressing the reset spring 35. The reset spring 35 is clamped between the pressure plate 36 and the inner wall of the clamping housing 1.

[0030] The pry bar 31 includes a hinge portion 312 hinged to the clamping housing 1, an ejector arm 311 for ejecting the clamping plate 2, and a pressure arm 313 for contacting the pressing plate 33. The ejector arm 311 and the pressure arm 313 are respectively located on both sides of the hinge portion 312. The pressure arm 313 and the ejector arm 311 are inclined away from each other to form a V-shape.

[0031] Accordingly, the vertical distance from the end of the pressure arm 313 to the hinge portion 312 is less than the vertical distance from the ejector arm 311 to the hinge portion 312, so that after the pressure arm 313 is pressed down, the ejector arm 311 can eject the clamping plate 2 outward.

[0032] Furthermore, the clamping device also includes a multi-functional counterweight box 4, and the clamping housing 1 is provided with a transition connector 5 for the fan to be mounted on the transition connector 5 and the clamping housing 1. The multi-functional counterweight box 4 is hinged to the bottom end of the transition connector 5 so that when the present invention is clamped on the display, the multi-functional counterweight box 4 can be adaptively adjusted according to the back of the display.

[0033] Furthermore, the multi-functional counterweight box 4 is equipped with a pivot 41 for hinged to the transition connector 5 and a torsion spring 42. The two working ends of the torsion spring 42 abut against the transition connector 5 and the multi-functional counterweight box 4, respectively, to maintain the relative position between the fan and the multi-functional counterweight box 4. The torsion spring 42 helps to prevent the clamping housing 1 from tilting and falling relative to the multi-functional counterweight box 4 when the invention is placed upright. At the same time, when the invention is in the clamping state, the multi-functional counterweight box 4 can be more closely attached to the display, thereby better stabilizing the clamping state between the clamping housing 1 and the clamping plate 2.

[0034] Furthermore, the multi-functional counterweight box 4 is equipped with a mobile power supply 6 for powering the fan, so as to avoid the fan being restricted by the location of power demand. At the same time, the center of gravity of the invention in the upright position can be lowered by utilizing the weight of the mobile power supply 6, thereby improving the stability in the upright position.

[0035] To facilitate power supply to the fan, the multi-functional counterweight box 4 is provided with a wiring channel 43, through which external wiring enters the multi-functional counterweight box 4.

[0036] Preferably, the clamping plate 2 is provided with an opening 21 for the camera, so that a viewing channel is left after the present invention is clamped on the display screen for normal use of the camera.

[0037] Accordingly, see Figures 1 to 3 The present invention also discloses a screen fan, including a fan and a clamping device, wherein the fan is mounted on the clamping housing of the clamping device. The structure of the clamping device is similar to... Figure 1 , Figure 2 and Figure 3 The clamping devices shown have the same structure, and their structural principles will not be described in detail here. The fan is existing technology, and its structural principles will also not be described in detail here.

[0038] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
