[0002] Greenhouses, also known as warm houses, refer to facilities used to grow plants. They are light-transmitting and heat-insulating (or heating). In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase production. They are mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low-temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, shapes and heating conditions. Greenhouses mainly include plastic film and skeleton structure.

[0003] At present, when greenhouse support frames are in use, in order to make the support frames easy to transport and store, many of them are supported by assembled support frames. When assembling and connecting the existing support frames, most of them use multiple bolts to fix the joints of the support frames. In this way, the time spent on connecting the support frames is long, the connection efficiency is low, and the disassembly and assembly process is more troublesome. Utility Model Content
