[0002] A handheld work lamp is a lighting tool. Existing handheld work lamps generally include a lamp holder, a barrel and a telescopic sleeve. The front end of the barrel has an interface sleeve. The lamp holder is detachably mounted in the interface sleeve of the barrel. The telescopic sleeve is located on the outside of the interface sleeve and slides back and forth along the axial direction of the interface sleeve. When the lamp holder needs to be replaced, the lamp holder can be removed from the interface sleeve by sliding the telescopic sleeve in one direction. The above-mentioned work lamp has shortcomings: the assembly structure between the lamp holder and the barrel is not only complicated and inconvenient to assemble and disassemble, but also has a blind spot for waterproof sealing, resulting in poor overall waterproof effect of the assembled lamp.
