Description

Optical instrument support frame of multi-angle regulation Technical Field The utility model belongs to the technical field of optical instrument support frames, and particularly relates to an optical instrument support frame with multi-angle adjustment. Background In the scenes of modern teaching, business demonstration, home film viewing and the like, a projector is widely used as an important optical display instrument, and a projector support frame becomes an indispensable auxiliary device for meeting different space layouts and use requirements. At present, although the existing projector support frames on the market have a certain multi-angle adjusting function, the problem of limited adjusting range generally exists, most of the traditional support frames can only realize small-range multi-angle and position adjustment, and are difficult to cope with complex and various installation environments, for example, in some irregular spaces or large-scale display places, the projection images are difficult to accurately project to a target area due to incapability of carrying out large-scale position movement and angle transformation, so that the using effect is influenced. Disclosure of utility model The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and to provide a multi-angle adjustable optical instrument holder which overcomes or at least partially solves the above-mentioned problems. The technical scheme is characterized in that the technical scheme comprises a multi-angle adjusting optical instrument support frame, a support column, a rotating plate, a clamping seat, a spherical connection, a support plate and mounting holes, wherein the support column is vertically arranged on the counterweight base, the rotating plate is rotatably connected to the upper end of the support column, the clamping seat is adjustable in clamping degree and fixedly connected to the end part of the rotating plate, the spherical connection is movably connected in a clamping groove of the clamping seat, the support plate is fixedly connected to the spherical connection, and the four corners of the support plate are provided with the mounting holes matched with supporting legs at the bottom of a projector.
