Detailed Description
The structure and the application method of the present invention will be described in detail with reference to the accompanying drawings. The utility model relates to parts such as push rod, pivot connecting rod, pivot, cutting knife, film reel, template connecting rod, template. In the following description, the directional descriptions such as "front", "rear", "front end", "rear end", etc. are referred to, wherein one end of the push rod, which is provided with the handle, is the rear end, and the other end of the push rod is the front end, and the above directional descriptions referred to in the description of the components such as the pivot connecting rod, the die plate connecting rod, the film roll, the die plate, etc. are referred to as front or front end toward one end of the push rod handle, and rear or rear end toward the other end of the push rod.
As shown in figures 1 and 2, the utility model comprises a push rod 1, a handle 2 is arranged at the rear end of the push rod, a rotating shaft connecting rod 3 is respectively connected with two sides of the middle part of the push rod, the rotating shaft connecting rod 3 inclines towards the outer side of the push rod, the rear ends of the two rotating shaft connecting rods 3 are respectively welded with two sides of the push rod 1, the front ends of the two rotating shaft connecting rods 3 are both bent towards the longitudinal axis direction of the push rod and are respectively connected with a threaded sleeve 4, one end of each threaded sleeve 4 is respectively in threaded connection with the front end of one rotating shaft connecting rod 3, the other end is respectively in threaded connection with two ends of a rotating shaft 5, the rotating shaft 5 is positioned at a certain distance at the front end of the push rod 1 and is vertical to the longitudinal axis of the push rod, a film reel 6 is sleeved on the rotating shaft, a cutting knife 7 is arranged at the top of the film reel 6, the two connecting plates 8 are respectively positioned at two ends of the film winding drum, and are provided with shaft holes and are rotatably arranged on the rotating shaft 5 through the shaft holes; the front edge of the cutting knife is provided with a cutting edge 9, and the cutting edge 9 can be arranged in a sawtooth shape. The top surface of the cutting knife is rotationally connected with a cutting knife operating lever 10.
During specific implementation, a hinge ball 11 can be welded on the top surface of the cutting knife 9, the hinge ball 11 is rotatably connected with the front end of the cutting knife operating rod 10, and the rear end of the cutting knife operating rod 10 faces the push rod handle 2.
