In the embodiment of the present disclosure, the arc-shaped diaphragm attachment surface 2112a is provided, so that the operation of attaching the film to the arc-shaped diaphragm 12 is facilitated. Referring to fig. 4 and 5, in the operation process of using the jig for attaching the film, the elastic limit stopper 221 is in the first state, the elastic limit stopper 221 encloses to form a limit space, and when the arc-shaped film 12 is placed into the limit space formed to be attached to the film attaching surface 2112a, the elastic limit stopper 221 protrudes, so that the position of the arc-shaped film 12 can be limited by the elastic limit stopper 221, and the arc-shaped film 12 is prevented from shifting. Next, the operator may place the target object to be attached to the arc-shaped film 12 on the limit stopper 221 for attachment. Here, the second state of the elastic stopper 221 will be described with respect to the fitting of the arc-shaped diaphragm, taking the target object as the eyeglass frame 11 as an example. Above-mentioned spectacle-frame 11 can be placed on elasticity limit stop 221, makes to keep certain interval between spectacle-frame 11 and the cambered membrane 12 owing to elasticity limit stop 221 protrusion this moment, conveniently adjusts the position of spectacle-frame 11 for spectacle-frame 11 and cambered membrane 12 position align. Finally, after the adjustment of the eyeglass frame 11 is stabilized, the eyeglass frame 11 is pressed down to make the elastic limit stop 221 in the second state, and at this time, the eyeglass frame 11 and the arc-shaped membrane 12 can be tightly attached, so that the arc-shaped membrane 12 is adhered to the eyeglass frame 11.
