Telescopic socket assembly
View Patent ↗A telescopic socket assembly includes an outer socket, an inner socket retractably and movably mounted in the outer socket, and an elastic member mounted between the inner socket and the outer socket. Thus, the telescopic socket assembly has an adjustable length and can be used to operate workpieces having different sizes. In addition, the telescopic socket assembly has a two-stage or three-stage position adjustment function.
1. A telescopic socket assembly, comprising:
an outer socket;
an inner socket retractably and movably mounted in the outer socket; and
an elastic member mounted between the inner socket and the outer socket;
wherein the inner socket has a peripheral wall formed with an adjusting hole, and the adjusting hole of the inner socket includes a longitudinally extended guide slot, a first positioning slot communicating with the guide slot, a second positioning slot communicating with the guide slot, and a third positioning slot communicating with the guide slot.
2. The telescopic socket assembly in accordance with claim 1 , wherein the adjusting hole of the inner socket is substantially E-shaped.
3. The telescopic socket assembly in accordance with claim 1 , wherein the first positioning slot of the adjusting hole of the inner socket is substantially T-shaped.
4. The telescopic socket assembly in accordance with claim 1 , wherein the first positioning slot of the adjusting hole of the inner socket has an upper end, a lower end, and a mediate portion connected to the upper end and the lower end and communicating with the guide slot.
5. The telescopic socket assembly in accordance with claim 1 , wherein the second positioning slot of the adjusting hole of the inner socket is substantially T-shaped.
6. The telescopic socket assembly in accordance with claim 1 , wherein the second positioning slot of the adjusting hole of the inner socket has an upper end, a lower end, and a mediate portion connected to the upper end and the lower end and communicating with the guide slot.
7. The telescopic socket assembly in accordance with claim 1 , wherein the third positioning slot of the adjusting hole of the inner socket is substantially T-shaped.
8. The telescopic socket assembly in accordance with claim 1 , wherein the third positioning slot of the adjusting hole of the inner socket has an upper end, a lower end, and a mediate portion connected to the upper end and the lower end and communicating with the guide slot.
9. The telescopic socket assembly in accordance with claim 1 , wherein the outer socket has a peripheral wall provided with two spaced fixing pins mounted in the adjusting hole of the inner socket, so that when the inner socket is moved in the outer socket, the two spaced fixing pins of the outer socket are moved in the adjusting hole of the inner socket relatively.
10. The telescopic socket assembly in accordance with claim 9 , wherein the two fixing pins of the outer socket are movably mounted in the guide slot of the adjusting hole of the inner socket and are positionable in either two of the first positioning slot and the second positioning slot or in the second positioning slot and the third positioning slot of the adjusting hole of the inner socket.
11. The telescopic socket assembly in accordance with claim 1 , wherein the outer socket has a peripheral wall provided with a fixing pin mounted in the adjusting hole of the inner socket, so that when the inner socket is moved in the outer socket, the fixing pin of the outer socket is moved in the adjusting hole of the inner socket relatively.
12. The telescopic socket assembly in accordance with claim 11 , wherein the fixing pin of the outer socket is movably mounted in the guide slot of the adjusting hole of the inner socket and is positioned in either one of the first positioning slot, the second positioning slot and the third positioning slot of the adjusting hole of the inner socket.
13. The telescopic socket assembly in accordance with claim 1 , wherein the outer socket has a first end formed with a square fixing hole, a second end formed with a hexagonal locking hole and a mediate portion formed with a cylindrical receiving hole.
14. The telescopic socket assembly in accordance with claim 13 , wherein the inner socket is slidably mounted in the receiving hole of the outer socket and has a first end formed with a square fixing hole.
15. The telescopic socket assembly in accordance with claim 13 , wherein the portion of the outer socket is provided with a shoulder located adjacent to the second end of the outer socket, and the elastic member is mounted in the receiving hole of the outer socket and has a first end urged on a second end of the inner socket and a second end urged on the shoulder of the outer socket.
16. The telescopic socket assembly in accordance with claim 1 , wherein the adjusting hole communicates with an inside of the inner socket.
