Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, a greenhouse includes a vertical rod 1, the top of the vertical rod 1 is connected with an arc rod 2 for supporting the tarpaulin, and a connecting mechanism 3 is arranged on the vertical rod 1 and the arc rod 2, and the connecting mechanism 3 is used to provide a limit for the connection of the vertical rod 1 and the arc rod 2;

[0030] The connecting mechanism 3 includes a transmission unit and a limiting unit;

[0031] The transmission unit is used to provide a pulling force for the movement of the limiting unit;

[0032] The limiting unit is used to provide a limit for the connection of the vertical rod 1 and the arc rod 2;

[0033] The transmission unit includes a pressing rod 301, a movable rod 302, a spring 303, and a pull rod 304;

[0034] The pressing rod 301 is vertically slidably installed on the inner wall of the vertical rod 1 and extends to the outside of the vertical rod 1, and the pressing rod 301 is used to drive the movable rod 302 to move synchronously;

[0035] The movable rod 302 is fixed at the top of the pressing rod 301 and is located inside the vertical rod 1, and the movable rod 302 is used to drive the pull rod 304 to move synchronously;

[0036] The two ends of the spring 303 are respectively clamped on the inner wall of the vertical rod 1 and the outer wall of the movable rod 302, and the spring 303 is used to provide a restoring elastic force for the movement of the movable rod 302;

[0037] The pull rod 304 is fixed at the top of the movable rod 302, and the pull rod 304 is used to give a rotational force to the rotating rod 305 during the movement;

[0038] The limiting unit includes a rotating rod 305, a limiting block 306, and a guiding groove 307;

[0039] The rotating rod 305 is rotatably installed in the inner cavity of the vertical rod 1, and the rotating rod 305 is used to drive the limiting block 306 to rotate synchronously;

[0040] The limiting block 306 is fixed to the top end of the limiting block 306. In the reset state, the limiting block 306 is used to provide a snap connection for the connection between the vertical rod 1 and the arc-shaped rod 2;

[0041] The guiding groove 307 is formed on the outer wall of the rotating rod 305, and the guiding groove 307 is used to receive the pulling force from the pulling rod 304.

[0042] In this embodiment: When using this device, by docking the top end of the vertical rod 1 with the bottom end of the arc-shaped rod 2, at this time, the docking grooves in the inner cavities of the top and bottom ends of the arc-shaped rod 2 and the limiting block 306 are cross-distributed. By applying a downward pressing force to the pressing rod 301, the pressing rod 301 drives the movable rod 302 to move downward synchronously. The downward movement of the movable rod 302 will apply a squeezing force to the spring 303 and simultaneously pull the pulling rod 304 downward. The downward moving pulling rod 304 transmits the pulling force to the guiding groove 307, causing the guiding groove 307 to drive the rotating rod 305 to rotate. The rotating rotating rod 305 will synchronously drive the limiting block 306 to rotate, so that the limiting block 306 rotates 90 degrees to align with the docking groove at the bottom end of the arc-shaped rod 2. At this time, the arc-shaped rod 2 will move downward, enabling the limiting block 306 to enter the inner cavity of the arc-shaped rod 2. When no downward pressure is applied to the pressing rod 301, the pressing rod 301 and the movable rod 302 are reset under the action of the spring 303, causing the limiting block 306 to rotate again and form a cross-shaped structure with the docking groove at the bottom end of the arc-shaped rod 2, completing the fixed connection between the vertical rod 1 and the arc-shaped rod 2, further improving the connection efficiency between the vertical rod 1 and the arc-shaped rod 2, and facilitating the separation of the vertical rod 1 and the arc-shaped rod 2.

[0043] Please refer specifically to Figures 1 - 3 , the outer wall of the guiding groove 307 is in a spiral state and is distributed at 90 degrees. The end of the pulling rod 304 matches the inner cavity of the guiding groove 307. A docking groove for the limiting block 306 to enter is formed in the inner cavity at the bottom end of the arc-shaped rod 2. The limiting block 306 and the docking groove are in a cross-shaped state in the initial state. A sliding groove for the vertical movement of the movable rod 302 is formed in the inner cavity of the vertical rod 1. The outer wall of the movable rod 302 is in an overall "T" - shaped structure. An activity groove for the vertical movement of the pressing rod 301 is formed on the outer wall of the vertical rod 1. A groove matching the outer wall at the bottom end of the arc-shaped rod 2 is formed in the inner cavity at the top end of the vertical rod 1.

[0044] In this embodiment: Through this structure, under the action of the "T" - shaped movable rod 302, when the movable rod 302 moves downward, the protruding part at the top end of the movable rod 302 will apply a downward pressure to the spring 303. When the spiral state of the guiding groove 307 receives the downward pulling force from the pulling rod 304, the guiding groove 307 will be stressed and drive the rotating rod 305 to rotate.
