When the second clamping portion 20 and the first clamping portion 10 cooperate to clamp the object a, a contact area between the second clamping portion 20 and the object a is larger than a contact area between the first clamping portion 10 and the object a, so that a friction force between the second clamping portion 20 and the object a is larger than a friction force between the first clamping portion 10 and the object a, and a friction force between the second clamping portion 20 and the object a is relatively larger so that the second clamping portion 20 and the first clamping portion 10 can stably clamp the object a.
According to the invention, the first clamping part 10 can be further provided with a first elastic material layer 11, the second clamping part 20 can be further provided with a second elastic material layer 21, the second elastic material layer 21 is arranged opposite to the first elastic material layer 11, when the second clamping part 20 and the first clamping part 10 clamp the object A, the object A is positioned between the first elastic material layer 11 and the second elastic material layer 21, and the first elastic material layer 11 and the second elastic material layer 21 can be deformed according to the shape of the object A so that the surface of the object A is respectively attached to the first elastic material layer 11 and the second elastic material layer 21, and the object A can be clamped stably by the first opening 3. The first elastic material layer 11 and the second elastic material layer 21 can both adopt silica gel, and the hardness of the first elastic material layer 11 is greater than that of the second elastic material layer 21, so that the clamped object A can be prevented from being twisted in the process of adjusting the clamping device 100.
