[0006] The handheld grinding device includes two operating rods connected by a spring tube on the left and right, and the end of each operating rod is connected to a grinding head via a motor.

[0007] The storage box is located at the bottom of the tool cart. The functional end cover is rotatably connected to the upper end of the storage box via a rotating shaft. The upper surface of the functional end cover is slidably connected to four bracket blocks arranged symmetrically in two sets via sliding grooves.

[0008] The purging device includes a fan located on the right side of the storage box, and an output air duct is connected to the outside of the fan;

[0009] The power supply box is located on the upper side of the fan, and the power supply box is equipped with wiring terminals. The wiring terminals are connected to the motor and the fan respectively through power lines.

[0010] Furthermore, the bracket block of this utility model includes a base block, and the upper end of the base block is provided with an arc-shaped rubber fastener, which facilitates the temporary placement of the handheld grinding device. The operating rod can be inserted into the corresponding arc-shaped rubber fastener.

[0011] Furthermore, the operating lever of this utility model is also provided with a threaded connection port for connecting the ball head handle, which makes it more convenient to operate by hand after the ball head handle is installed.

[0012] Furthermore, in this invention, the two operating levers on the left and right sides are provided with matching locking hooks at their central positions. When not in use, the two locking hooks can be connected to merge the two operating levers together for easy storage.

[0013] Furthermore, the operating lever of this utility model is provided with a wire harness clip on its side wall, and the tool cart is also provided with a tube clip on its side wall.

[0014] The beneficial effects of this utility model are: the concrete crack width detection pretreatment device of this utility model can deburr the left and right edges of the concrete crack to make them relatively smooth, and then use a portable blowing device to clean out the scattered dust and debris in the crack, providing a good detection environment for the subsequent width detection and further improving the detection accuracy.
