Device for screwing and unscrewing bolts/nuts |
| 摘要 |
Device for screwing and unscrewing bolts/nuts, comprising a lever, two jaws mounted between two side plates, with spacers guiding and holding the components together. The said lever rotates a certain angle around an axis moving the two jaws inward or outward. When move inward the jaws clutch the bolt head/nut and when move outward the bolt head/nut is released. The screwing or unscrewing is done without retracting the device out of the axis of the bolt/nut.;The device is much more suitable when used for threaded fittings along the pipes or cable connectors like those for coaxial TV cable. |
