The invention discloses a handheld dust collector. The handheld dust collector comprises a cylinder body and a dust collecting cover detachably connected to the lower end of the cylinder body. The dust collecting cover is detachably connected to the lower end of the cylinder body through the clamping connection of a pair of moving parts and the cylinder body. The moving parts are driven by a corresponding driving assembly to move, so that the moving parts are connected with or separated from the cylinder body. The driving assembly comprises a rack, a first gear, a second gear and a third gear.The rack is in sliding fit with a pair of second guide seats on the dust collecting cover. The first gear is meshed with the rack. The second gear and the first gear are coaxially arranged. The thirdgear is meshed with the second gear. The third gear is meshed with the gear ring on the dust collecting cover. Due to the adoption of the structure, quick disassembly and quick assembly between the cylinder body and the dust collecting cover are realized. The dust in the dust collecting cover is convenient to clean.
