[0023] Embodiment 1:

[0024] With reference to Figures 1-7 A bamboo hardcover book cover, comprising a book cover 1, the book cover 1 is an open upward box body, the bottom of the book cover 1 is connected with a bottom plate 2, wherein the book cover 1 comprises a main cover 10 and a sub-cover 11, a sliding groove 3 is formed in the end face of the sub-cover close to the main cover 10, a sliding plate 4 is fixedly arranged at one end of the sub-cover 11, the sliding plate 4 extends into the sliding groove 3, a recess 5 is also formed in the bottom plate 2, the main cover 10 and the sub-cover 11 are located in the recess 5, and the bottom of the main cover 10 is fixedly connected with the recess 5, the sub-cover 11 is movably connected with the recess 5, in the process of adjusting the size, the sub-cover 11 can move on the bottom plate 2, the main cover 10 and the sub-cover 11 are connected through an adjusting mechanism 6, the adjusting mechanism 6 is mainly used for adjusting the overall size of the book cover 1, adjusting grooves 7 are formed in the two sides of the main cover 10, a plurality of clamping grooves 8 are also formed in the two sides of the adjusting grooves 7, the purpose of the clamping grooves 8 is to clamp the adjusting structure after adjustment, so that the overall size of the book cover 1 is fixed.

[0025] The end of the bottom plate 2 away from the main cover 10 is also movably connected with an upper cover 9, the upper cover 9 is movably connected by a plurality of strip plates, the upper cover 9 is in bamboo strip type, which is convenient to store and take out, and can play a protection role while not occupying space when rolled up.

[0026] The other end of the main cover 10 is fixedly provided with an arc-shaped paste plate 12, and the arc-shaped surface of the arc-shaped paste plate 12 is opposite to the bottom surface of the upper cover 9, so that the upper cover 9 can be better retracted in the process of being pulled tight, and the upper cover 9 will not be loosely covered on the book cover 1.

[0027] The adjusting mechanism 6 comprises a sliding block 60, a rotating shaft 61, a gear 62, a clamping block 63, a pin 64, an adjusting handle 65 and a connecting arm 66, the sliding block 60 is movably installed in the adjusting groove 7, the rotating shaft 61 is arranged in the sliding block 60, the gear 62 is matched on the rotating shaft 61, the other end of the rotating shaft 61 extending out of the sliding block 60 is fixedly provided with the adjusting handle 65, the clamping blocks 63 are movably arranged on the two sides of the sliding block 60, the pins 64 are arranged at the ends of the clamping blocks 63, the pins 64 are in rack structure, and the pins 64 of the two clamping blocks 63 are engaged with the gear 62, the connecting arm 66 is fixedly arranged at one end of the sliding block 60, and the other end of the connecting arm 66 is fixedly connected with the sliding plate 4.

[0028] Adjusting principle:

[0029] When the size of the book case 1 needs to be changed, the magnetic strip 13 and the adsorption block 14 between the upper cover 9 and the main case 10 and the auxiliary case 11 are first separated, then the adjusting handle 65 is twisted to make the clamping block 63 retract, so that the clamping block 63 is separated from the clamping groove 8, and then the sliding block 60 can slide along the adjusting groove 7, and the connecting arm 66 drives the sliding plate 4 to move in the sliding groove 3, so that the distance between the auxiliary case 11 and the main case 10 can be adjusted, thereby realizing the size adjustment. After the adjustment, the adjusting handle 65 is twisted in the opposite direction to make the clamping block 63 extend out of the sliding block 60 and cooperate with the corresponding clamping groove 8, that is, to be locked, so that the auxiliary case 11 cannot be moved.
