One end of the locking rod 25 is inserted into the interior of the locking sleeve 23, and an adapter block 27 adapted to the locking rod 25 is slidably installed in the inner cavity of the limiting slide groove 24, and a spring 26 is fixedly connected to one side of the adapter block 27, and one end of the spring 26 away from the adapter block 27 is fixedly connected to the inner wall of the slide rail 22, and a protrusion 210 adapted to the limiting slide groove 24 is fixedly connected to the surface of the locking rod 25, and a connecting plate 211 is fixedly connected to the surfaces of the two protrusions 210.

[0026] The specific usage process is as follows: first, the user opens the front cover 4 and can write on the blank writing page 3, and the front cover 4 is opened and closed around the two hinge components 2. This is the existing technology and will not be explained in detail in the text. After writing on a writing page 3, the writing page 3 is turned to one side of the front cover 4 so that the next writing page 3 can continue to be written on urgently. If the writable writing pages 3 are not enough, the number of writing pages 3 can be flexibly increased. Specifically, the user moves the spring 26 to one side of the front cover 4, so that the spring 26 can simultaneously drive the two locking rods 25 to slide toward the inner cavity of the limiting slide groove 24, and at the same time push the adapter block 27 to slide in the inner cavity of the limiting slide groove 24, and the adapter block 27 will compress the spring 26. At this time, the end of the locking rod 25 originally inserted in the inner cavity of the second limiting slide groove 28 will move out of the inner cavity of the second limiting slide groove 28, and then the gap between the slide rail 22 and the lock sleeve 23 will open, and then the user can put the unwritten paper on the two lock sleeves 23 until the increased number is met.
