The housing 11 includes a top wall 111, a bottom wall 112, and a peripheral side wall 113 connecting the top wall 111 and the bottom wall 112. The top wall 111, the bottom wall 112, and the peripheral side wall 113 enclose a receiving space. The housing 11 has a pressing hole 114, a light emitting hole 115, and a mounting hole 116.

The fixing member 12 is accommodated in the accommodating space. One end of the fixing member 12 elastically abuts against the bottom wall 112, and a gap exists between the opposite end of the fixing member 12 and the top wall 111. The gap is for accommodating the dust guard 20. The other end of the fixing member 12 opposite to the other end is adapted to elastically abut the dust-proof member 20 accommodated in the gap against the top wall 111.

In this embodiment, the dustproof fixing assembly 10 is applied to a line laser 3D profile measuring apparatus, and is used for installing and fixing the dustproof member 20, and protecting the light-transmitting glass 40 by using the dustproof member 20, so as to play a dustproof role. The dustproof fixing assembly 10 provided by the application is convenient for quick replacement of the dustproof piece 20, and can improve the replacement speed of the dustproof piece 20, so that the production efficiency of the line laser 3D profile measuring instrument in use is improved.
