[0021] The projector with single-arm holder structure comprises an L-shaped holder 1 and a projector body 2, the projector body 2 is in the shape of a cylinder, the projector body 2 comprises a front half and a rear half, the arc-shaped side wall of the rear half of the projector body 2 is rotationally connected with the upper end of the holder 1 through a damping rotating shaft, and the center point of the front end face of the projector body 2 is located above the center point of the rear end face of the projector body 2 when the front end face and the rear end face of the projector body 2 are perpendicular to the horizontal plane.

[0022] Preferably, the angle between the line connecting the center point of the front end face of the projector body 2 and the center point of the rear end face of the projector body 2 and the horizontal plane is 0.5 degrees when the front end face and the rear end face of the projector body 2 are perpendicular to the horizontal plane, so that the overall posture of the projector is in the posture of the lens end being upward when the projector is working, thereby effectively avoiding the phenomenon of the lens end of the projector body being downward, and further ensuring the projection effect.

[0023] Specifically, the holder 1 comprises a circular bottom plate 3 and a rectangular vertical plate 4, the lower end of the right side wall of the vertical plate 4 is connected with the outer circumferential surface of the bottom plate 3, and the left side of the rear half of the projector body 2 is rotationally connected with the upper end of the right side wall of the vertical plate 4 through a damping rotating shaft.

[0024] In the embodiment, the upper end of the vertical plate 4 is in the shape of a convex semicircle, the edge of the lower end face of the bottom plate 3 is chamfered, the upper edge, the front edge and the rear edge of the left side wall of the vertical plate 4 and the front edge and the rear edge of the lower end face of the vertical plate 4 are respectively chamfered, and the angles of the chamfers are consistent with the angle of the edge chamfering of the lower end face of the bottom plate 3.

[0025] Further, the lower edge of the left side wall of the vertical plate 4 is provided with a convex round corner, the lower end face of the vertical plate 4 is flush with the lower end face of the bottom plate 3, and the connection portions of the right side wall, the front side wall and the rear side wall of the vertical plate 4 with the bottom plate 3 are respectively provided with concave round corners, through the chamfering and the round corner processing, the edges of the bottom plate 3 and the vertical plate 4 which are easy to be contacted by the user are processed, so that the appearance of the entire projector is more beautiful and round, and the phenomenon that the sharp edges may hurt the user is avoided.

[0026] In the embodiment, the lower surface of the bottom plate 3 is provided with a silica gel pad, so that not only a good damping effect is achieved, but also the friction between the bottom plate 3 and the surface on which the projector is placed is increased, thereby reducing the risk of the projector being easily tilted.

[0027] The damping rotating shaft usually comprises:

[0028] The nut damping structure is composed of a movable frame, a fixed frame, a connecting shaft, a spring washer, a limiting washer, an oil storage washer and a nut, and has adjustable torsion and stable service life.

[0029] The package type damping structure mainly has a rotating sleeve and a connecting shaft, has small assembly space and simple assembly.

[0030] The elastic sheet type damping structure utilizes the elastic deformation and friction of the elastic sheet to generate damping, and the structure is relatively simple, and is commonly used in some small devices with high space requirements.

[0031] The working principle of the damping rotating shaft is that the friction and extrusion between internal components generate a torque that hinders rotation, such as extrusion between gaskets, damping material action, etc., to slow down or control the rotating action, and the damping force size can be controlled by adjusting the number of gaskets, nut tightness, damping adjustment device, etc.

[0032] It should be noted that the damping rotating shaft is a mature product, so as long as it can meet the requirements of the rotating connection between the support 1 and the projector body 2 in the utility model, any structure of the damping rotating shaft is acceptable, so it is not described here, and the user can make appropriate adjustments according to the specific production and sales requirements.

[0033] The working principle of the utility model is that when in use, only one hand is needed to hold the adjustment projector body 1, and the angle of the two ends of the projector body 1 is adjusted, and the working characteristics of the damping rotating shaft are used to make the angle of the projector adjustment hover at any angle.

[0034] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the description.

[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which are within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
