Problems solved by technology

[0002] At present, for projection devices with adjustable lens position, if there is no special mechanism for users to adjust the position of the projection lens from the outside, the user needs to use a screwdriver to insert the inside of the machine for adjustment, but the position of the adjustment screw may vary with the position of the lens. Position shifts, making it difficult to align the screwdriver with the adjusting screw

Abstract

The invention provides a guide device. The guide device is used for adjusting the positions of the lens of a projecting device. The lens is provided with an adjusting screw, the guide device comprises a fixing frame and a guide mechanism, the guide mechanism is of a hollow structure and is provided with a first end and a second end, the first end and the second end are arranged oppositely, the first end is arranged at the position of the adjusting screw in a sleeved mode, the second end is in pivot joint with the fixing frame in a movable mode, and the included angle between the tangent plane of the outer surface of the guide mechanism and the horizontal plane is a first included angle. When the adjusting screw moves and adjusts the positions of the lens, the adjusting screw drives the guide mechanism to move, and therefore the angle of the first included angle is changed. The guide mechanism of the guide device is arranged on the adjusting screw in the sleeved mode, when the adjusting screw of the lens moves, the adjusting screw drives the guide mechanism to move to change the angle of the guide mechanism, and therefore a screwdriver can be guided to the position of the adjusting screw accurately through the guide mechanism.

Description

technical field [0001] The invention relates to a guiding device and a projection device with the guiding device, in particular to a guiding device with a variable angle and a projection device with the guiding device. Background technique [0002] At present, for projection devices with adjustable lens position, if there is no special mechanism for users to adjust the position of the projection lens from the outside, the user needs to use a screwdriver to insert the inside of the machine for adjustment, but the position of the adjustment screw may vary with the position of the lens. Position shifts, making it difficult to align the screwdriver with the adjusting screw. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a guiding device and a projection device with the guiding device. By sheathing the guiding mechanism outside the adjusting screw, the adjusting screw drives the guiding mechanism to move, and the screwdri...
