Abstract

The invention relates to a foot stand which is applied to a projection device. The foot stand comprises a connecting member, a telescopic assembly, a suction disc and a pusher, wherein the connecting member is used for being connected with the projection device and is provided with a spherical joint; the telescopic assembly is provided with a first end part and a second end part which are opposite to each other; the first end part is rotatably connected to the spherical joint; the telescopic assembly comprises at least two sliding parts which are arranged in a mutual sliding manner; the two sliding parts are used for sliding relatively, so as to change the length of the telescopic assembly; the suction disc is fixedly arranged at the second end part; the pusher is arranged at the second end part in a sliding manner; when the pusher is located at a first position, the pusher is far away from the suction disc; when the pusher is located at a second position, the pusher pushes the suction disc, so as to squeeze out air between the suction disc and a surface, and thus, the suction disc is adsorbed to the surface.

Description

technical field [0001] The invention relates to a tripod, and in particular to a tripod of a projection device. Background technique [0002] The projection device can project images on a larger screen so that more people can watch the content displayed on the screen at the same time, so it is often used in companies, schools, families and other occasions. With the advancement of science and technology, various types of electronic products are developing toward high speed, high performance, thinness and shortness. Under this trend, multimedia pico projectors (or mini projectors) have gradually become the future personal The mainstream of the digital market. In addition to placing the projection device on the desktop for use, the user can also use an additional fixing mechanism to fix the projection device on structures such as ceilings or walls. However, most of the fixing methods of the known fixing mechanisms are labor-intensive and time-consuming, and it is difficult to...
