[0007] According to the above technical solution, the receiving plate is slidably installed on the circumferential surface of the fixing rod, a fixing hole is opened on the surface of the connecting member body, and a threaded groove is provided on the surface of the rotating rod. By rotating the rotating rod and driving the extrusion block through the threaded groove and the fixing hole to further extrude the support column, the support column is extruded and moves toward the direction close to the fixing platform and contacts the fixing platform, thereby achieving the fixation of the support column.

[0008] According to the above technical solution, one end of the extrusion block close to the support column is set as bevel surface 1, and bevel surface 1 can facilitate extrusion and support of the support column. A No. 1 spring is arranged between the receiving plate and the connecting member body. The receiving plate moves to extrude the No. 1 spring to contract, and under the action of the No. 1 spring and the extrusion block, preliminary support for the support column is achieved. One end of the U-shaped rod close to the fixed platform is set as bevel surface 2, and the receiving plate moves through the bevel surface 2 to extrude the U-shaped rod downward.

[0014] The present invention provides a connecting piece for installing a greenhouse, which has the following beneficial effects:

[0015] (1) The greenhouse installation connector, when the support column moves, the limit on the extrusion block is released under the action of the receiving button and the U-shaped rod, and the initial support of the support column is achieved under the action of the telescopic elastic rod. There is no need for workers to provide additional support to the support column, which reduces the work intensity of the workers and ensures the stability of the support column in the vertical direction. Subsequently, the support column is fixed by rotating the rotating column and under the action of the threaded groove and the fixing hole, further improving the installation efficiency of the greenhouse support column.

[0016] (2) When the angle of the support column needs to be adjusted, the limit on the T-bar is released by moving the sliding rod, and then the T-bar is moved downward to release the limit on the connecting shaft. During the process of rotating the connecting shaft to adjust the angle, the L-shaped plate is squeezed and moved by the cross bar and the push rod, and the connecting shaft is provided with additional support under the action of the block to avoid tipping due to the change of the force angle due to angle adjustment, thereby affecting the stability of the support column, thereby improving the applicability of the support column installation and use. At the same time, the sliding rod can effectively prevent the support column from being adjusted by accidental touch, thereby reducing safety hazards.

[0017] (3) The greenhouse installation connector, the L-shaped plate moves through the sliding plate and the second spring to maintain stability during the angle adjustment process, avoiding excessive rotation speed and tipping due to the support column itself during the adjustment process. The partition can effectively prevent soil from entering the interior of the chute four, thereby affecting the stability during the adjustment process and increasing subsequent maintenance costs. The movement of the sliding plate causes the receiving block and the semicircular block to repeatedly contact and vibrate. The vibration can effectively loosen the soil and stones on the surface of the connecting base, avoiding soil or stones from affecting the angle adjustment of the support column, thereby improving the convenience of equipment use.
