[0002] An elevator is a common fixed lifting device in a floor building, which is used for carrying people or goods in high-rise buildings. When a fault occurs during the long-term use of the elevator or during daily maintenance, it is often necessary to use a lighting device in cooperation for supplementary lighting, so as to facilitate maintenance personnel to perform fault detection and maintenance on the elevator.

[0003] A Chinese patent with the publication number of CN218001212U discloses a portable lighting device for elevator maintenance, which includes a mounting base. A plurality of connecting suction cups for adsorption and fixation are symmetrically arranged on the outer side of the mounting base. In this portable lighting device for elevator maintenance, the mounting base, a telescopic rod, a connecting cavity and a lighting connecting seat form a telescopic structure, and the outer end of the lighting connecting seat and two connecting lamp boards installed with LED lighting lamps form a flipping mechanism. The device can perform stable external lighting through the extension of the telescopic rod and the flipping out of the connecting lamp boards. And through the contraction and limitation of the telescopic rod to the connecting cavity and the storage and placement of the connecting lamp boards in the clamping grooves inside the lighting connecting seat, the device can be stably folded and stored, so as to facilitate maintenance personnel to carry and transport the device. At the same time, through the rotation of the lighting connecting seat and the tightening and loosening adjustment of the top-positioning screws on the outer side of the lighting connecting seat, the flipping direction and lighting angle of the two connecting lamp boards at the outer end of the lighting connecting seat can be stably flipped and adjusted and fixed.

[0004] However, the above patent has the following deficiencies: The above patent fixes the lighting lamp in the elevator shaft through the cooperation of connecting suction cups and magnetic adsorption connecting plates. During the use process, there is a certain risk of dropping for the lamp fixed only by suction cups and magnetic adsorption connection, so it needs to be improved. Summary of the Utility Model
