DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a deep-drawing resistant protective film, comprising a fixed seat 1, a protective film body 3, a movable seat 5 and a cutting knife 6, a sleeve rod 2 is fixedly connected to the middle position of one side of the fixed seat 1, and the protective film body 3 is sleeved on the outside of the sleeve rod 2. By providing the sleeve rod 2 on one side of the fixed seat 1, the protective film body 3 can be sleeved on the outside of the sleeve rod 2;

[0021] A base layer 301 is disposed in the middle of the protective film body 3. The base layer 301 is a common polyester film on the market, which is relatively hard and scratch-resistant, thus ensuring the overall strength of the protective film.
