After the buyer is bought, the buyer needs to cut according to the size without special cutting tools, so that the cutting difficulty is high and the workload is large. The plastic or wooden partition plate needs to be manufactured in a large area to achieve the protection purpose, and materials are consumed and wasted. And the cleanliness of the partition plate is difficult to guarantee, and if the cleanliness is unqualified, the cylinder body is polluted, so that the cleanliness of the cylinder body is unqualified. The clapboard is difficult to recycle and occupies large space. The cylinder body can only be protected in the transportation process by the scheme, and the scheme has no protective effect in the up-and-down hoisting process.

The baffle only plays the protection to the transportation, can't guarantee that the cylinder body does not receive to collide with when hoist and mount from top to bottom. In addition, the partition board occupies a certain space, the space for transporting the material racks is limited, the arrangement of the air cylinder bodies cannot be reasonably arranged, more material racks are needed, and the waste of resources is caused.

There is an urgent need to design a protection device in the process of hoisting and transporting cylinder bodies, and the device needs to be reusable, simple and convenient.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
