Claims (5)
1. A quick-change structure for a screw cap is characterized by comprising a three-groove structure and three clamping jaws slidably mounted on the three-groove structure, wherein two first sliding grooves with included angles of 120 degrees and second sliding grooves with included angles of 120 degrees with the two first sliding grooves are formed in the top of the three-groove structure; the clamping jaws are correspondingly connected in the first sliding groove and the second sliding groove and are vertically distributed downwards in a regular triangle shape, the length of the second sliding groove is greater than that of the first sliding groove, and the second sliding groove penetrates through the geometric center of the three-groove structure, so that a driving groove is formed between the clamping jaws connected in the second sliding groove and the second sliding groove; the upper part of the inner side of the clamping jaw is provided with a lug, and the height of the lug is not higher than the upper surface of the three-groove structure; and connecting structures are arranged on two sides of the second sliding groove.
2. The screw cap quick-change structure according to claim 1,
corresponding to each sliding chute, a vertical positioning structure is arranged below the end part of each sliding chute of the three-chute structure, and each positioning structure is provided with an adjustable structure which protrudes outwards; the length of the downward protrusion of the positioning structure is less than that of the downward protrusion of the clamping jaw.
3. The screw cap quick-change structure according to claim 1,
the connecting structure is a bolt hole penetrating through the three-groove structure.
4. The screw cap quick-change structure according to claim 1,
the first sliding groove and the second sliding groove are T-shaped grooves.
5. A cap opening and closing robot, characterized by comprising the cap screwing and quick changing structure of the claims 1-4.
