A lamp holder with an angle adjusting device is used for achieving adjustment of the angle of the lamp holder, and the inclination angle of the lamp holder can be known about conveniently. The lamp holder with the angle adjusting device comprises a lamp holder body and a support; a first supporting lug is arranged on the front side of the lamp holder body; a second supporting lug is arranged on the rear side of the lamp holder body; corresponding through holes are formed in the first supporting lug and the second supporting lug; an installation ring is fixed to the first supporting lug, and an installation ring is fixed to the second supporting lug; the first supporting lug and the second supporting lug are each provided with a locking device; the support comprises a first installing plate, a second installing plate and a connecting plate; a scale plate is fixed to each of one end of the first installing plate and one end of the second installing plate; the two installing rings are rotationally connected with the corresponding scale plates; a rotating shaft is fixed between the two installing rings and fixedly provided with a worm gear; a worm is rotationally installed between the first installing plate and the second installing plate; and the two scale plates are each provided with inserting holes and each provided with scale marks. By means of the lamp holder with the angle adjusting device, the inclination angle of the lamp holder can be conveniently adjusted, and the lamp holder can be relatively fixed.
Description
technical field [0001] The invention relates to the technical field of lamp caps, in particular to a lamp cap with an angle adjustment device. Background technique [0002] Most of the lamp caps and fixing brackets in the prior art are fixedly connected, and the angle of the lamp caps cannot be adjusted, so the use is limited. Even if some lamps have the function of adjusting the lamp head, their structures are complicated and the manufacturing cost is relatively high. For example, the Chinese patent application with the application number of 201010210766.4 discloses a device for adjusting the angle of the lamp head, which includes: a fixed seat, a rotating seat, a connecting piece passing through the fixed seat and the rotating seat, a locking piece for locking the connecting piece, and an inner gear plate and external gears. The structure of the above-mentioned lamp head is complex, and when the angle is adjusted, the inclination angle of the lamp head cannot be clearly ...
