Description

Technical Field

[0001] This application relates to the field of power tool technology, and more specifically to a power tool with a removable battery. Background Technology

[0002] Existing power tools require a matching power source, but the power source and the tool are usually not detachable, causing inconvenience in use and maintenance. (Application number: 202022863073) Patent No. 7 discloses a handheld air pump, including a housing, an air pump assembly installed inside the housing, and a battery box. The housing has a handheld part, and the battery box is detachably connected to the lower end of the handheld part. The air pump assembly includes a motor, a cylinder, a drive wheel, and a driven wheel. The front end of the cylinder is connected to an inflation nozzle via a one-way valve. The inflation nozzle is fixed to the front end of the housing. The cylinder is mounted on a cylinder base. The drive wheel, driven wheel, and motor are all fixed on the cylinder base. The drive wheel is connected to the motor and drives the driven wheel to rotate. The cylinder piston is connected to the driven wheel, and the rotation of the driven wheel drives the cylinder piston to move in the cylinder. The air pump assembly also includes a first blade and a second blade. The motor is a dual-shaft motor. The upper shaft is connected to the drive wheel, the first blade is coaxially connected to the drive wheel, and the lower shaft of the motor is connected to the second blade. The motor is located in the handheld part of the housing, and the housing has ventilation holes. Although this air pump allows the battery box to be detached from the handheld part, the battery box can only be used with air pumps of the corresponding model, resulting in poor applicability.
