[0002] As an important traction vehicle in a train, a railway locomotive generates mechanical power through a high-power internal combustion engine, which enables the locomotive to produce strong traction to pull the train carriages. Because there are many internal parts in a railway locomotive, it needs to be inspected regularly after a long period of use. In order to make it easier to carefully observe the inspection location of the railway locomotive, maintenance personnel often need to carry lighting equipment to illuminate the designated location for lighting work. In order to improve efficiency, a special lighting device for railway locomotive maintenance is often used.

[0003] To address this, patent specification CN214198225U discloses a lighting device for railway locomotive maintenance, comprising a base, a first soft strap fixedly connected to one side surface of the base, and a second soft strap fixedly connected to the other side surface of the base. A sleeve is provided on one side surface of the first soft strap, and rubber buckles are provided on one side surface of the second soft strap. The number of rubber buckles is the same as the number of sleeves. A groove is provided on the outer surface of the base, and a tube is disposed inside the groove. A screw hole is provided on one side surface of the tube, and a lampshade is threaded into the screw hole. This utility model, through the coordinated use of the first soft strap, the second soft strap, the rubber buckles, and the sleeve, allows maintenance personnel to easily wear the base on their heads, and is suitable for different maintenance personnel to wear, eliminating the need for holding or having someone else hold it, thus improving the efficiency of hand-held locomotive repairs.
