Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 2 and fig. 3, a release film leveling structure of a film pasting device, wherein a film pasting device 20 is rectangular, a positioning space 21 is formed on a bottom surface of the film pasting device, a protection sticker 22 is disposed in the positioning space 21, a release film 23 is detachably pasted on the bottom surface of the protection sticker 22, and the release film 23 includes a pasting portion 24, a turning portion 25 and an extending portion 26; the attaching portion 24 is adhered to the protection sticker 22, the bending portion 25 is located between the attaching portion 24 and the extending portion 26, and the bending portion 25 is bent reversely to form a bending end 251, so that the extending portion 25 can be bent relatively and detachably overlapped with the attaching portion 24, the extending portion 26 is longer than the protection sticker 22, and one end of the extending portion 26, which is far away from the bending end 251, is exposed out of the outer edge of the film attaching device 20; the film pasting device 20 is provided with a pressing pad 27 to press the turning part 25, wherein a positioning post 201 is respectively arranged on the bottom surface of the film pasting device 20 at two sides of the turning part 25, the pressing pad 27 is provided with two positioning holes 271 respectively corresponding to the positioning posts 201, so that the pressing pad 27 presses the end 251 of the turning part 25, and the positioning post 201 is pressed to be plugged in the positioning hole 271, thereby pressing the end 251 of the turning part to prevent the turning part 25 from deforming and warping, and achieving the effect of being easy to flatten.
