Angle fine adjustment device of wall-mounted fixing device for wall-mounted instrument

Abstract

The invention discloses an angle fine adjustment device of a wall-mounted fixing device for a wall-mounted instrument. The angle fine adjustment device comprises a supporting rod, a lever, a fine adjustment bolt and a high-precision fine adjustment bolt; the supporting rod is one of two supporting rods of the wall-mounted fixing device for the wall-mounted instrument; the supporting rod and a nail hanging notch form a three-point support stable structure on a wall; one end of the lever is located behind the supporting rod and located between the fine adjustment bolt and the supporting rod; and the high-precision fine adjustment bolt is used for spirally pushing a power arm of the lever to pry the fine adjustment bolt and the supporting rod to slightly push the supporting rod to slightly move, so that high-precision angle fine adjustment of the wall-mounted fixing device for the wall-mounted instrument is realized. The angle fine adjustment device of the wall-mounted fixing device for the wall-mounted instrument has the beneficial effects that the angle fine adjustment precision of the wall-mounted fixing device for the wall-mounted instrument can be effectively improved; and the device is provided with the two fine adjustment bolts, so that fine adjustment and high-precision fine adjustment can be achieved, and the wall-mounted fixing device for the wall-mounted instrument is more convenient to use.

Description

technical field [0001] The invention relates to the field of building decoration tools, in particular to an angle fine-tuning device for a wall-mounted fixing device for a wall-mounting instrument. Background technique [0002] The wall sticking instrument is a kind of laser reference light emitting device commonly used in the field of decoration. [0003] Chinese Patent Announcement ZL201820071093.0 Wall-hanging Fixing Device for Wall Mounting Instrument, the device is mainly composed of a gap hanging arm, a hammer connecting arm, a support plate and two angle fine-tuning support screws, and the angle fine-tuning device of the device has the following deficiencies: the device The fine-tuning uses a fine-tuning screw for both fine-tuning and supporting the supporting plate. Because its length is too long, it will inevitably bend. The fine-tuning accuracy is not easy to grasp, and the adjustment of the light beyond ten meters away by the spiral push alone requires an adjustm...

[0003] Chinese Patent Announcement ZL201820071093.0 Wall-hanging Fixing Device for Wall Mounting Instrument, the device is mainly composed of a gap hanging arm, a hammer connecting arm, a support plate and two angle fine-tuning support screws, and the angle fine-tuning device of the device has the following deficiencies: the device The fine-tuning uses a fine-tuning screw for both fine-tuning and supporting the supporting plate. Because its length is too long, it will inevitably bend. The fine-tuning accuracy is not easy to grasp, and the adjustment of the light beyond ten meters away by the spiral push alone requires an adjustment accuracy of one millimeter or otherwise. For most users, the accuracy is still not easy to grasp.
