The connecting plate 224 that slides in the length direction of the column 222, the guide column 222 is sleeved with a telescopic extension spring 223 for sliding the pressing plate 221 towards the direction of the placement plate 2, and one end of the telescopic extension spring 223 is fixedly connected with the connecting plate 224, stretching The other end of extension spring 223 is fixedly connected with placement plate 2, and guide column 222 is provided with prism structure, and the cross-sectional dimension of pressure plate 221 is smaller than the cross-sectional dimension of ledger placement area 21, and top plate 3 is provided with the guide that guide column 222 passes through. Hole 33.

The device design of this fixing mechanism 22 is firstly to slide the pressing plate 221 along the length direction of the guide column 222 while the telescopic tension spring 223 is stretched under force, then put the ledger that needs to be cut into the ledger placement area 21, then release the pressing plate 221, The pressure plate 221 is contracted by the elastic force of the telescopic tension spring 223 and plays a role in fixing the books on the book storage area 21. In addition, the guide column 222 is designed as a prismatic structure to prevent the pressure plate 221 from rotating on the guide column 222 and affect the pressing. In addition, the size of the pressing plate 221 is further limited. The length of the pressing plate 221 should be smaller than the length of the ledger placement area 21, and the width of the pressing plate 221 should be smaller than the width of the ledger placement area 21, so as to avoid the occurrence of excessive pressing of the pressing plate 221. It greatly affects the actual cutting effect of the cutting knife 3115 on the books in the book placement area 21, and the top board 3 is provided with a guide hole 33 for the guide column 222 to pass through. The downward movement distance will not be affected by the existence of the guide column 222.

First, it protects the safety of the user and prevents the cutting knife 3115 from cutting the user due to improper operation; second, it plays the role of protecting the cutting knife 3115, preventing external things from affecting the user. The use of cutting knife 3115 causes cutting knife 3115 to wear too fast and thus affects the service life of cutting knife 3115; the 3rd coaming board 5 can prevent the phenomenon that the paper dust that cutting produces is due to the reason of external wind flying wildly when the 3rd, in addition The surrounding board 5 can be set to a detachable structure. When the cutting knife 3115 needs to be replaced, the surrounding board 5 can be removed to facilitate the replacement of the cutting knife 3115. When working, the surrounding board 5 can be installed on the top plate 3 to play a protective role. .

The knife holder 3113 is provided with an infrared emitter 6 for marking the position of the cutting knife 3115. The infrared emitter 6 is arranged to emit downwards along the sliding direction of the top plate 3. The design of the infrared emitter 6 allows the user to emit The infrared ray can check the cutting position, so that the user can intuitively know whether the cutting position is accurate. If it is not accurate, the sliding block 3111 can be moved to quickly locate the position of the infrared ray, which not only saves time but also has high accuracy. The operation is convenient and simple, and it can play an easy-to-understand role in teaching.
