[0017] In order to more clearly illustrate the technical solution of the utility model, the drawings required for use in the description will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4The thin film applicator with a key-operated core that can be easily replaced is shown in the figure, and has a shell 1, a core 2 is arranged inside the shell, and the shell 1 is composed of a sheath 3, a front cover 4, a rear cover 5, a function key 6 and a key 7. The sheath 3 is fixedly connected to the front cover 4, and an elastic component 8 is arranged between the inside of the sheath 3 and the inside of the front cover 4. The elastic component 8 cooperates with the function key 6 and the key 7 to make the head of the core 2 pop out when working and retract when not working; the front cover 4 and the rear cover 5 are connected by a pivot element 9, and the pivot element 9 drives the rear cover 5 to flip in a direction away from the front cover 4, and the rear cover 5 Flipped backward and downward around the pivot position, the front cover 4 is provided with a button hole 10, and the rear cover 5 is provided with an elastic button 11, the button hole 10 and the elastic button 11 are used together to realize the opening and closing of the rear cover 5 and the front cover 4; a function key 6 is provided on the top of the rear cover 5, and a button 7 is provided on the top of the function key 6; the belt core 2 is embedded in the hollow cavity surrounded by the front cover 4 and the rear cover 5, the head of the belt core 2 is against the end of the elastic component 8, and the tail of the belt core 2 is against the free end of the function key 6, and the hollow cavity structure surrounded by the front cover 4 and the rear cover 5 matches the shape structure of the belt core 2.

[0020] The shape of the pivot element 9 is "H"-shaped, and the upper and lower parts of the "H"-shaped pivot element 9 are pivotally connected to the rear cover 5 and the front cover 4 respectively. The pivot element 9 drives the rear cover 5 to flip 70 degrees away from the front cover 4, and the rear cover 5 flips 70 degrees backward and downward around the pivot position.

[0021] The function key 6 is provided with a working position and a resting position, and the function key is switched between the working position and the resting position when the key is pressed.

[0022] During use, the function key 6 is pushed into the working position by pressing the button 7 with one hand, thereby pushing the belt core 2 downward to squeeze the elastic component 8, so that the head of the belt core pops out of the sheath to work; after the work is completed, the button 7 is pressed again to make the function key 6 enter the rest position, the force squeezing the elastic component 8 disappears, the elastic component 8 is reset and pushes the belt core 2 back into the hollow cavity.

[0023] When the belt core is used up and needs to be replaced, press the button hole 10 on the front cover 4 with one hand to make the elastic button 11 on the rear cover 5 withdraw from the button hole 10, and the pivot element 9 drives the rear cover 5 to flip 70 degrees in the direction away from the front cover 4, and the rear cover 5 flips 70 degrees backward and downward around the pivot position, so that the rear cover 5 is located on the side of the front cover 4, fully exposing the belt core 2, so that the belt core can be easily taken out and replaced with a new one, and then the rear cover 5 is flipped back to its original position, and the elastic button 11 is embedded in the button hole 10, and the rear cover 5 is fixedly connected to the front cover 4, so that the belt core replacement work can be completed simply, conveniently and quickly, and there is no need to worry about the loss of parts.
