Detailed Description

In order to make the noble examiner conveniently and concisely understand the other characteristic contents and advantages of the utility model and the achieved efficacy thereof can be more shown, the utility model is matched with the accompanying drawings, and the detailed description is as follows:

referring to fig. 3, the present invention provides a projector with an arm supporting and fixing frame, which includes: a fixed part 1, a first arm 2, a second arm 3 and a projector 4.

The fixing portion 1 has a first pivot portion 11, and the fixing portion 1 can be a fixing plate. The fixing portion 1 may be provided with at least one fixing hole 12.

The first arm 2 has a first end 21 of the first arm and a second end 22 of the first arm, the first end 21 of the first arm is pivoted to the first pivot portion 11 of the fixing portion 1, and the second end 22 of the first arm has a second pivot portion 23.

The second arm 3 has a first end 31 of the second arm and a second end 32 of the second arm, the first end 31 of the second arm is pivoted to the second pivot 23 of the first arm 2, and the second end 32 of the second arm has a connecting portion 33. The connecting portion 33 can be a pivot structure or a fixed structure, depending on the actual requirement.

The projector 4 is provided with a combined part 41, and the combined part 41 is connected with the connecting part 33, so that the projector 4 can be pivoted with the second end 32 of the second arm or fixedly connected with the second end 32 of the second arm. The projector 4 may be a Digital Light Processing (DLP) projector, a Liquid Crystal On Silicon (LCoS) projector, or a Liquid Crystal Display (LCD) projector.

For further understanding of the structural features, technical means and expected effects of the present invention, the usage of the present invention will be described as follows:
