The invention belongs to the field of interior decoration, and particularly relates to a wallpaper laminating machine with convenient wallpaper tightening. The wallpaper laminating machine comprises abase, a main shaft and a secondary shaft are rotatably connected into the base, one end of the main shaft and one end of the secondary shaft mesh with each other through gears, and a wallpaper outletis formed in the bottom surface of the base. The left end of the main shaft penetrates out of the base, a cylindrical protrusion is arranged outside the right side wall of the base, rotating pieces are rotatably connected to the left end of the main shaft and the cylindrical protrusion, the two rotating pieces are fixedly connected into a whole through a connecting rod, and a telescopic rod is vertically installed on the middle part of the connecting rod. An outer hexagonal screw head is coaxially fixed to the left end surface of the main shaft, and the outer hexagonal screw head is providedwith a socket spanner in a matched mode. The wallpaper laminating machine with convenient wallpaper tightening has the beneficial effects that the left end of the main shaft can be used as a rotatingshaft of the corresponding rotating piece to facilitate the rotation of the telescopic rod, and the outer hexagonal screw head can be further arranged so that the socket spanner conveniently drives the main shaft, so that wallpaper and isolation protection paper are tightened and retracted; and the function of wallpaper retracting and the function of rotating of the telescopic rod around the baseare integrated, the structure is simple and operation is convenient.
