Embodiment Construction

[0032] The preferred implementation of the electric tool will be described below with reference to the accompanying drawings.

[0033] Please refer to figure 1 , an embodiment of the power tool 100 includes a driving member 110 and an air pump attachment 120, and the driving member 110 is used to drive the air pump attachment 120 to carry out inflation work. The electric tool 100 is an electric pump, wherein the driving member 110 can be a power tool such as an electric drill, a screwdriver, etc., with an output shaft that can rotate around its own axis.

[0034] Please refer to figure 1 The driving member 110 is provided with a casing 112 and an output shaft 114 extending out of the casing 112 and capable of rotating around its own axis. The casing 112 is provided with a motor (not shown) to drive the output shaft 114 to rotate, which can be connected to a built-in battery or an external power source so that the motor can drive the output shaft 114 to work. This point is we...

Abstract

The invention relates to an electric tool. The electric tool comprises a drive piece and an inflator accessory. The drive piece is provided with a machine shell and an output shaft. The inflator accessory comprises a shell and an inflating assembly arranged in the shell, wherein the shell is provided with a connector used for being connected with the output shaft in a matched mode, the connector is rotationally sleeved with a locking sleeve, an elastic piece is connected between the connector and the locking sleeve, and the machine shell is provided with an installing part connected with the locking sleeve in a matched mode. The installing part is provided with a plurality of positioning blocks in the circumference direction of the installing part. A groove is formed by adjacent positioning blocks. Locking blocks capable of moving leftwards and rightwards in the grooves and sliding forwards in the grooves are arranged on the inner sides of the locking sleeve, and the positioning blocks extrude the locking blocks in the locking block forward sliding process to enable the locking blocks to rotate relative to the shell. During installing, the locking blocks can be buckled on the positioning blocks only by pushing the inflator accessory to move forwards, dismounting can be achieved only by rotating the locking sleeve to enable the locking blocks to be aligned with the grooves to be pulled out, the mounting operation and the dismounting operation are easy, and the inflator accessory is replaced conveniently.

Description

technical field [0001] The invention relates to the technical field of power tools, in particular to an electric tool with the function of an air pump.
