The two side arms 21 are further provided with a connecting member 30, and the film frame 10 is connected to the two side arms 21 through the connecting member 30, so as to be detachably mounted in the accommodating space 23. The supporting seat 20 further includes a base 22, and the two side arms 21 are oppositely disposed at two sides of the upper end of the base 22.

In this embodiment, the film frame 10 includes two side plates 11, a first connecting portion 12 and a second connecting portion 14. The two side plates 11 are oppositely arranged, and the first connecting portion 12 and the second connecting portion 14 are oppositely arranged at two ends of the two side plates 11 and connected with the two side plates 11, so that the film rack 10 is approximately a square frame. The two side plates 11 are connected to the two side arms 21 by the connecting members 30, and the film frame 10 is detachably mounted in the accommodating space 23.

It can be understood that the width between the two side arms 21 is slightly larger than the width between the two side plates 11, and the two side plates 11 are respectively installed inside the corresponding side arms 21, so that the film frame 10 is installed in the accommodating space 23 formed by the two side arms 21.

Referring to fig. 3, the connecting member 30 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is disposed outside the side plate 11 of the film frame 10. The first connecting member 31 may be an elastic clamping member. The second connecting member 32 is disposed outside the side arms 21. The second connector 32 may be a hook. When the first connecting member 31 is engaged with the second connecting member 32, the two side plates 11 are respectively connected to the two side arms 21, so that the film frame 10 is installed in the accommodating space 23, that is, the film frame 10 is connected to the supporting seat 20. When the first connecting piece 31 is separated from the second connecting piece 32, the film frame 10 can be separated from the supporting seat 20.

Further, the first connecting member 31 includes a connecting plate 311, an elastic member 312 and a fastening member 313. The connecting plate 311 is a substantially inverted L-shaped strip, and includes a first plate 3111 and a second plate 3112. The first plate 3111 and the second plate 3112 are perpendicular to each other. The end of the first plate 3111 is embedded in the outer side of the side plate 11 of the film holder 10 and is movably connected to the side plate 11. The second plate 3112 is exposed on the surface of the side plate 11 and spaced apart from the side plate 11.

The elastic member 312 and the fastening member 313 are both substantially cylindrical. One end of each of the elastic member 312 and the fastening member 313 is embedded in the side plate 11, and the other end passes through the second plate 3112 and is fixedly connected to the second plate 3112. The elastic member 312 is retractable, and one end of the elastic member embedded in the side plate 11 abuts against the side plate 11. After the fastening member 313 is embedded in the side plate 11, it can move a distance in the side plate 11. The surface of the fastening member 313 exposed at one end of the side plate 11 forms a first inclined plane 3131. The second connector 32 is a substantially inverted L-shaped plate, and a hook 321 is formed at one end of the second connector adjacent to the first connector 31. The hook 321 is close to the outer side of the first connector 31, and a second inclined surface 3211 is formed corresponding to the first inclined surface 3131.

A plurality of unwinding module supports 121 are arranged on the first connecting portion 12 at intervals to form a plurality of accommodating spaces for accommodating the unwinding modules 13. The unwinding module 13 includes an unwinding roller 131 and a plurality of positioning discs 132. The unwinding roller 131 is used for mounting the roll material 40, and the positioning plate 132 is used for positioning the roll material 40. The unwinding module supports 121 are used for erecting the unwinding roller 131. The positioning plates 132 are fixedly installed on the unwinding roller 131 at intervals to form at least one accommodating channel 1311 for placing the rolled material 40. The unwinding roller 131 is provided with a plurality of damping members 133 and floating members 134. The damping member 133 is a damping adjustment screw. The roll 40 is mounted on the unwinding roller 131 so as to be wound on the floating member 134 and is accommodated in the accommodating passage 1311.
