Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-3A protective film slitting device with safety protection function includes a worktable 1, a transmission mechanism 5 mounted on the worktable 1, and a protective film body 4 located on the transmission mechanism 5. The transmission mechanism 5 is used to automatically adjust the position of the protective film body 4. A support frame 3 is mounted on the worktable 1, and the support frame 3 is close to the side wall of the transmission mechanism 5. An mounting block 2 is mounted on the support frame 3. An electric push rod is horizontally mounted on the support frame 3. The mounting block 2 is fixedly mounted on the output end of the electric push rod, so that the mounting block 2 can automatically move back and forth by moving the output end of the electric push rod. A positioning block 17 is fixedly mounted on the bottom of the mounting block 2. A snap-fit ​​block 16 is slidably connected to the bottom of the mounting block 2. The snap-fit ​​block 16 and the positioning block 17 are mounted opposite each other on the bottom of the mounting block 2. A horizontal groove 14 is provided on the bottom of the mounting block 2. A slider 15 is fixedly installed on the top of the snap-fit ​​block 16. The slider 15 is slidably connected to the groove 14. By sliding the slider 15 to the groove 14, the snap-fit ​​block 16 can move laterally within a certain range, thereby adjusting the distance between the positioning block 17 and the snap-fit ​​block 16. A cutter 9 is snapped into the inside of the positioning block 17 and the snap-fit ​​block 16, and a threaded sleeve 8 is threadedly connected to the outside. The cutter 9 is close to the side wall of the protective film body 4. Both the snap-fit ​​block 16 and the positioning block 17 have reverse threads 12 on their outer walls. A threaded sleeve 8 is connected to the outside of the snap-fit ​​block 16 and the positioning block 17 via two reverse threads. The cross-sectional diameters of the positioning block 17 and the snap-fit ​​block 16 gradually increase from bottom to top. By rotating the threaded sleeve 8 to the outside of the positioning block 17 and the snap-fit ​​block 16, the distance between the positioning block 17 and the snap-fit ​​block 16 is minimized, thus fixing the top of the tool 9 below the mounting block 2, achieving the effect of fixing the tool. When it is necessary to remove the tool 9, simply remove the threaded sleeve 8 to remove the tool 9. In the middle, the side wall of the positioning block 17 is provided with a mounting groove 6, and the inside of the mounting groove 6 is equipped with a spring positioning component. The cutter 9 is provided with a through hole 10. The end of the spring positioning component away from the mounting groove 6 passes through the through hole 10 and engages with the cutter 9. Thus, the cutter 9 can be stably installed between the positioning block 17 and the locking block 16 by engaging the positioning key 11 with the through hole 10, thereby achieving a fixing effect. By the elastic force of the positioning spring 7, when the locking block 16 is close to the positioning block 17, the part of the positioning key 11 extending outside the mounting groove 6 can retract within a certain range, thereby preventing the components from getting stuck.

[0025] In this embodiment, a positioning groove 13 is provided on the side wall of the snap-fit ​​block 16. The end of the positioning key 11 away from the positioning spring 7 extends through the through hole 10 into the interior of the positioning groove 13. By snapping the positioning key 11 into the positioning groove 13, the positioning key 11 can be more stable, avoiding displacement and loss of engagement with the through hole 10, which would cause the tool 9 to fall off.

[0026] Working principle: When it is necessary to disassemble the tool 9, the threaded sleeve 8 is removed by rotation, and then the locking block 16 is moved horizontally to remove the tool 9 from the positioning key 11. When it is necessary to install and fix the tool 9, the tool 9 can be locked on the positioning key 11, and then the threaded sleeve 8 is installed on the outside of the positioning block 17 and the locking block 16 by rotation, so that the positioning block 17 and the locking block 16 form a whole, thereby achieving the effect of fixing and installing the tool 9, and further facilitating the replacement of the tool 9.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
