Specifically, the limiting hook 301 is rotatably mounted on the frame 450, when the flip cover 430 is in the cover-closing state, the limiting hook 301 is clamped with the rubber roller 210, so that the rubber roller 210 is limited, and when the flip cover 430 is in the cover-opening state, the limiting hook 301 can rotate to release the limitation of the rubber roller 210. The limiting hook 301 is connected with a cover opening slider 312, and when the cover opening slider 312 slides, the limiting hook 301 can be pulled to rotate, which is specifically implemented by providing sliding guide holes, such as a first sliding guide hole 317 and a second sliding guide hole 318, on the frame 450 and the limiting hook 301. In order to improve the safety of uncovering, the uncovering protection mechanism 300 is provided with a first swing rod 302 and a third spring 313 at a position corresponding to the safety position 206 of the cutter assembly 100, when the cutter assembly 100 enters the safety position 206, the cutter assembly 100 can be abutted against the pushing first swing rod 302, the first swing rod 302 compresses the third spring 313 and pushes the second swing rod 303 outwards, the second swing rod 303 deflects outwards, a limit block 319 on the second swing rod 303 releases the limit of the third swing rod 304, the limit of the limit hook 301 is released by the third swing rod 304, the limit hook 301 can be driven to rotate when the uncovering slide block 312 slides, the limit hook 301 releases the limit of the rubber roll 210, the turnover cover 430 can be opened, and the rubber roll 210 can leave along with the opening of the turnover cover 430. It should be noted that, when the second swing rod 303 deflects outwards, one end of the bottom of the second swing rod 303 toggles the fourth swing rod 305, and toggles the fifth swing rod 306 to rotate through the fourth swing rod 305, where the fourth swing rod 305 and the fifth swing rod 306 form a link mechanism, the fifth swing rod 306 toggles the sixth swing rod 307 to deflect outwards, and the limiting block 319 of the sixth swing rod 307 leaves the limiting position, so that the sixth swing rod 307 releases the limit of the seventh swing rod 308, and further the seventh swing rod 308 releases the limit of the limiting hook 301. The first swing rod 302 and the tenth swing rod 311 are in a symmetrical structure, the second swing rod 303 and the sixth swing rod 307 are in a symmetrical structure, the second swing rod 303 is provided with a first return spring 314, the sixth swing rod 307 is provided with a second return spring 315, and the third swing rod 304 and the seventh swing rod 308 are in a symmetrical structure.
In addition, referring to fig. 1, 13 and 15, the first swing link 302 is mounted with the flip 430, and the first swing link 302 is separated from the second swing link 303 along with the rotation of the flip 430 during the opening process of the flip 430, and the second swing link 303 is reset due to the loss of the pushing force of the first swing link 302, so that the stopper 319 of the second swing link 303 again limits the third swing link 304. In order to avoid this, a cam 431 is disposed on the rotating shaft of the flip 430, and during the rotation of the flip 430, the cam 431 drives the eighth swing rod 309 to rotate, so that the eighth swing rod 309 can be clamped between the second swing rod 303 and the frame 450, and the second swing rod 303 is prevented from resetting due to losing the pushing force of the first swing rod 302. The eighth swing link 309 is connected with a third return spring 316, when the flip cover 430 is in the closed state, the cam 431 releases the pushing force on the eighth swing link 309, so that the eighth swing link 309 releases the limit on the second swing link 303 under the action of the third return spring 316. The eighth swing link 309 and the ninth swing link 310 have symmetrical structures.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
