[0025] When encountering snowfall, start the vibration motor 94 to drive a part of the L-shaped piece 9 to vibrate. The L-shaped piece 9 will drive the mounting strip 92 thereon to vibrate while vibrating. When the mounting strip 92 vibrates, the film 41 will vibrate back and forth. As the film 41 vibrates, the snow on it will be vibrated off, thereby achieving the purpose of snow and ice removal.

[0027] The connecting mechanism includes a pair of movable screws 31 movably arranged on the end vertical plate 29. A pair of movable long holes 30 are opened on the end vertical plate 29. The length direction of the movable long holes 30 is parallel to the length direction of the end vertical plate 29. The movable screws 31 are inserted into the movable long holes 30. The outer end of the movable screws 31 is installed with a movable block 32. The lower wall of the movable block 32 contacts with a V-shaped spring piece 33. The V-shaped spring piece 33 is installed with a mounting plate 34. The mounting plate 34 is arranged on the end vertical plate 29. The movable block 32 An upper clamping plate 39 is installed on the upper end of the upper clamping plate 39, and the inner end of the upper clamping plate 39 is a wedge-shaped structure.

[0029] When replacing the film 41, the operator rotates the outer plate 36 outward so that the action rod 37 on the rotating outer plate 36 cancels the action on the boss. Thereafter, the upper clamping plate 39 will move upward under the action of the V-shaped spring piece 33, thereby canceling the clamping of the film 41 and then replacing the film 41.

[0030] When fixing the film 41, the operator places the two ends of the film 41 between the upper clamping plate 39 and the lower clamping plate 40, and then rotates the rotating outer plate 36. The rotation of the rotating outer plate 36 will cause the outer periphery of the action rod 37 to act on the upper end of the boss, and then clamp the film 41 through the upper clamping plate 39 and the lower clamping plate 40.
