The utility model discloses a portable trepanning device for thermoplastic films. The portable trepanning device comprises a sleeve with an open lower end, a plurality of liftable blade mounting plates and barbs are further arranged in the sleeve, and the barbs are all located on the outer sides of the blade mounting plates; and a cutting blade is mounted on the blade mounting plate. When the low-temperature thermoplastic memory film is perforated, the low-temperature thermoplastic memory film can be perforated at any position of the body surface of a patient in an online manner without waiting for the low-temperature thermoplastic memory film to be cooled, hardened and shaped on the body surface of the patient, and the low-temperature thermoplastic memory film is far away from the body surface of the patient in the cutting process, so that the comfort level of the patient is better; meanwhile, the trepanning process can be rapidly completed, the waiting time of a patient is shortened,and the workload of a te
