The phrase "at least one of," when combined with a list of items, refers to a single item in the list or any combination of items in the list. The phrase does not require all of the listed items unless explicitly so limited.

The embodiment of the application discloses a clamping tool for clamping fluoroplastic work piece. Referring to fig. 2, the clamping jig for clamping fluoroplastic workpieces comprises a jig body 1 with two ends, a connecting block 2 formed by protruding the end face of one end of the jig body 1, and a bonding piece 3 arranged on the jig body 1. The connecting block 2 is used for being connected with the three-jaw chuck 9, and the bonding piece 3 is used for connecting the jig body 1 and the fluoroplastic workpiece 8.

Specifically, in order to enable the clamping jig for clamping the fluoroplastic workpiece to be connected more stably by the three-jaw chuck 9, the connecting block 2 is cylindrical. When the connecting block 2 is arranged in a clamping space formed by the clamping teeth of the three-jaw chuck 9 in a surrounding manner, the clamping teeth of the three-jaw chuck 9 can be abutted against the outer wall of the connecting block 2 and can clamp the outer wall of the connecting block 2.

When processing fluoroplastic workpiece 8, fluoroplastic workpiece 8 can be connected with the one end of tool body 1 through bonding piece 3. One end of the jig body 1, which is far away from the fluoroplastic workpiece 8, is connected with the three-jaw chuck 9 through the connecting block 2. When processing fluoroplastics work piece 8 into cyclic annular gasket, because of safety consideration, the processing tool can not be too close to three-jaw chuck 9, when being connected tool body 1 and fluoroplastics work piece 8 through connecting block 2, connecting block 2 has increased the distance between fluoroplastics work piece 8 and the three-jaw chuck 9, can make more fluoroplastics work piece 8 processed, has improved fluoroplastics work piece 8's effective use rate.
