摘要

The present invention discloses a novel soft collet including a gripping part made of an elastic material and a connection part. The gripping part includes at least two fingertips matched with each other for gripping. A finger gap is formed between the fingertips, and a finger cavity is arranged inside each fingertip. The connection part includes a communication chamber which is communicating with each finger cavity. The connection part is provided with a communication port communicating with the communication chamber. The fingertip includes an inner wall close to the finger gap and an outer wall remote from the finger gap. The thickness of the inner wall is smaller than that of the outer wall, or the elastic modulus of the inner wall is smaller than that of the outer wall. The soft collet is suitable for gripping tiny objects. Additionally, the present invention further discloses a soft fixture and a soft gripping pen, both of which use the soft collet and also have the above-mentioned advantages.
