Detailed Description

A portable lighting device of a level is shown in figure 1 and comprises a level 1 and a glare flashlight 2, wherein the glare flashlight 2 is connected with the top surface of the level 1 through a rotatable connecting part. The connecting part comprises a T-shaped bracket 3 and a bracket seat 4, the upper part of the T-shaped bracket 3 is an arc-shaped metal supporting plate 301 which is horizontally arranged, the lower part of the T-shaped bracket 3 is a positioning shaft 302 which is vertically arranged, and the highlight flashlight 2 is arranged in the arc-shaped metal supporting plate 301. The bracket seat 4 is a magnetic ring which is adsorbed on the top surface of the level 1, the middle part of the magnetic ring is a positioning hole 401 which is in clearance fit with the positioning shaft 302 of the T-shaped bracket, and the upper surface of the magnetic ring is provided with a longitudinal limiting groove 402 and a transverse limiting groove 403. The longitudinal limiting groove 402 and the transverse limiting groove 403 are clamped with the arc-shaped metal supporting plate 301. Two ends of the highlight flashlight 2 are fixed with the arc-shaped metal supporting plate 301 through the rubber ring 5. The fit clearance between the positioning shaft 302 and the positioning hole 401 is not more than 1 mm. The longitudinal limiting groove 402 and the transverse limiting groove 403 are formed by adhering 4 plastic sheets or foam double-sided adhesive on the upper surface of the magnetic ring around the axis of the magnetic ring.
