Firstly, an operator places a proper amount of books in the left and right book carrying shelves 76 and places the books between the rubber positioning plates 77 of the spices, when the operator stands on the right side to fetch the books and a required book is in the left book carrying shelf 76, the operator can push the corresponding wheel disc 73 to rotate, the wheel disc 73 rotates to drive the rotating rod 71 to rotate, the rotating rod 71 rotates to drive the transmission assembly 72 to rotate, the transmission assembly 72 rotates to drive the rotating shaft 74 to rotate, the rotating shaft 74 rotates to drive the cam 78 to rotate, the cam 78 rotates to drive the pull wire 79 to move inwards, the return spring 710 is stretched, the rotating shaft 74 rotates to drive the connecting plate 75 to rotate, the connecting plate 75 rotates to drive the book carrying shelves 76 to rotate, the book carrying shelves 76 rotates by one hundred eighty degrees, the pushing of the corresponding wheel disc 73 is stopped, the required book can be fetched from the book carrying shelves 76, the wheel disc 73 is loosened after the required book is fetched, because of reset spring 710's effect, the outside removal of acting as go-between 79 drives cam 78 and rotates and resets, cam 78 rotates and resets and drives pivot 74 and rotate and reset, just also make rim plate 73 rotate one hundred eighty degrees and reset, and pivot 74 drives year bookshelf 76 and rotates one hundred eighty degrees and reset, and the same thing, when operating personnel stands in the left side, promote corresponding rim plate 73 and rotate, just also make year bookshelf 76 rotate one hundred eighty degrees, it rotates one hundred eighty degrees and makes the book on right side rotate to the left side to carry bookshelf 76, the back is taken off to the book, loosen corresponding rim plate 73, it also drives the book rotation and resets just also to carry bookshelf 76. Therefore, the operator does not need to walk to the other side to take down the required books, and time and labor are saved.

When a book on the other side is needed, the corresponding clamping plate 81 is pulled to move outwards to be separated from the book carrying frame 76, the contraction spring 86 is stretched, the clamping plate 81 moves outwards to drive the corresponding rack 82 to move outwards, the rack 82 moves outwards to drive the gear 83 to rotate forwards, the gear 83 rotates forwards to drive the rack 82 on the other side to move outwards, the rack 82 on the other side moves outwards to drive the clamping plate 81 on the other side to move outwards to be separated from the book carrying frame 76, the contraction spring 86 on the other side is stretched, the clamping plate 81 is stopped being pulled, the corresponding wheel disc 73 is pushed to rotate, the book carrying frame 76 rotates one hundred eighty degrees, the book on the other side rotates to the front of an operator, the needed book can be taken down, the wheel disc 73 is released to reset, the book carrying frame 76 drives the book to rotate to reset, the clamping plate 81 is released again, the clamping plate 81 moves inwards to reset and is inserted into the book carrying frame, the reset of the position-limiting plate 81 drives the rack 82 to move inwards for resetting, the rack 82 resets and drives the rack 82 on the other side to move inwards for resetting through the gear 83, and the position-limiting plate 81 on the other side also moves inwards for resetting. Thus, the phenomenon that the book shelf 76 swings to affect the placement of books can be avoided.

Referring to fig. 5 and 6, the article taking mechanism 9 is further included, the article taking mechanism 9 includes a fixing rod 91, an L-shaped block 92, a positioning spring 93 and a limiting rod 94, the fixing rod 91 is fixedly connected between the lower portions of the right sides of the front and rear sides in the left side book carrying frame 76 and between the lower portions of the left sides of the front and rear sides in the right side book carrying frame 76, the L-shaped block 92 is sleeved on the fixing rod 91 in a rotating manner at uniform intervals in the circumferential direction, the L-shaped block 92 is located between adjacent rubber positioning plates 77, two positioning springs 93 are connected between the outer bottom of the L-shaped block 92 and the inner bottom of the book carrying frame 76, the limiting rod 94 is fixedly connected to the left side of the inner bottom of the left side book carrying frame 76 and the right side of the inner.

Still including show mechanism 10, show mechanism 10 is including transparent panel 101, connecting plate 102 and screens lock 103, and front and back 1 lateral surface of both sides backup pad left side upper portion all articulates there are two connecting plates 102, and the rotary type is connected with transparent panel 101 between two connecting plates 102 tail ends, and transparent panel 101 is embedded places in

backup pad

1, and 1 inside upper and lower both sides of backup pad all bilateral symmetry are equipped with screens lock 103, screens lock 103 and transparent panel 101 contact cooperation.

When a book is placed in the book bearing frame 76, the book contacts the L-shaped block 92, an operator can attach a label written with a corresponding book name to the L-shaped block 92, and then when the book on the other side rotates to the front, the operator can see the label to know the position of the required book, pull the upper part of the L-shaped block 92 corresponding to the required book to swing downwards, swing the upper part of the L-shaped block 92 downwards to enable the lower part to swing upwards, the positioning spring 93 is stretched, swing the lower part of the L-shaped block 92 upwards to drive the book to swing outwards, stop pulling the L-shaped block 92 when the L-shaped block 92 swings ninety degrees, take down the required book, release the L-shaped block 92, and reset the lower part of the L-shaped block 92 downwards due to the action of the positioning spring 93, so that the upper part of the L-shaped block 92 swings upwards. Therefore, people can know the required book more clearly and can take down the book conveniently.

After the book was all placed, pulling transparent panel 101 outwards removed, transparent panel 101 outwards removed and drives connecting plate 102 luffing motion, and transparent panel 101 outwards removed and screens lock 103 breaks away from, and then connecting plate 102 luffing motion ninety degrees, stops pulling transparent panel 101 outwards to remove, puts into transparent panel 101 with the catalogue of the book of placing on bearing frame 3, promotes transparent panel 101 inwards to remove again and resets, screens lock 103 is fixed transparent panel 101. In this way, it is possible to make it clear which books are on the carrier 3.
