The utility model discloses a laser displacement sensor shell using a diffusion lens and a linear polarizer in a combined mode, and particularly relates to the field of photoelectric measurement. Comprising a lower shell, the upper cover of the lower shell is provided with a cover plate, the lower shell comprises a bottom plate, the surface of the bottom plate is vertically connected with a U-shaped first baffle, a second baffle is connected between the opening ends of the first baffle, and a first groove and a second groove are formed in the second baffle at intervals; the first groove is located at the receiving end of the laser displacement sensor. A first connecting plate is connected between the opening ends of the first grooves, and a first through hole matched with the first linear polarizer is formed in the first connecting plate; the second groove is located at the transmitting end of the laser displacement sensor; a second connecting plate is connected between the two inner side walls of the second groove, and two second through holes parallel to each other are formed in the second connecting plate. Through the shell, the laser displacement sensor body and each optical element can be integrally packaged.
