The support device 100 includes a base 1, a first support 2, a second support 3, and a driving member 4.

The base 1 is used to support a first support 2, a second support 3 and a drive 4. The first support 2 is rotatably disposed on the base 1, for example, the first support 2 is disposed on the top end of the base 1 through a first rotation shaft. The second supporting member 3 is rotatably disposed on the base 1, for example, the second supporting member 3 is disposed on the top end of the base 1 through a second rotating shaft. A supporting space is formed between the first support 2 and the second support 3, for example, the supporting space is V-shaped, and the supported member 200 is placed in the supporting space. The first support 2 and the second support 3 cooperate to support the supported member 200.

The driving member 4 is disposed on the base 1, and is configured to drive the first supporting member 2 and the second supporting member 3 to rotate in opposite directions, so that the first supporting member 2 and the second supporting member 3 are close to or far away from each other, so as to adjust the angle a of the supporting space.

As shown in fig. 3 and 4, when the first support 2 and the second support 3 are close to each other, the angle a of the support space becomes small so as to support the supported member having a small diameter. When the first support 2 and the second support 3 are away from each other, the angle a of the support space becomes large so as to support the supported member having a large diameter.

Alternatively, the first support 2 and the second support 3 are both substantially sector-shaped, and the tip of the first support 2 and the tip of the second support 3 are disposed upward, and the curved end of the first support 2 and the curved end of the second support 3 are in driving connection with the driving member 4.

The utility model supports the supported member 200 through the cooperation of the first support member 2 and the second support member 3, thereby avoiding unnecessary rolling of the supported member 200. The rotation of the first support 2 and the second support 3 can adjust the angle of the supporting space to fit the supported members 200 of different diameters.

In some embodiments, the driving member 4 includes a screw 41, where the screw 41 is rotatably disposed on the base 1, and the screw 41 is in driving connection with the first support member 2 and the second support member 3 to drive the first support member 2 and the second support member 3 to rotate in opposite directions.
