However, for easy operation, in this embodiment, the support rod, the shell 2, the clamping plate fixing rod 32, the fixed connecting rod 33, and the movable connecting rod 34 are all made of aluminum material, and the handle 52 is made of PVC material to reduce the weight of the device; the connecting rope is made of a rigid steel wire rope to better transmit the telescopic pulling force; the first return spring 36 and the second return spring 53 are both made of high-quality alloy steel; the clamping plate 1 is made of hard stainless steel material to avoid deformation of the clamping plate 1 due to repeated use while ensuring the light weight of the device, and extend the service life of the book picking and placing device.

[0032] The usage method of the book picking and placing device disclosed in this embodiment is as follows:

[0033] When it is necessary to pick up a book, place the clamping plate 1 on both sides of the book and hold the handle 52 tightly. At this time, the driving connecting rod 51 moves, and drives the telescopic control rod 35 to move through the connecting rope. The two clamping plate fixing rods 32 approach each other, and the clamping plate 1 closes to complete the picking up of the book. At this time, the first return spring 36 and the second return spring 53 are also compressed; after the book picking and placing are completed, release the handle 52, and the first return spring 36 and the second return spring 53 stretch. Under the action of the elastic forces of the two return springs, the driving connecting rod 51 and the telescopic control rod 35 return to the initial position, the clamping plate 1 opens, and the book picking and placing device returns to the initial state.
