Jack handle with means for limiting the torque which can be applied to a jack |
摘要 |
A jack handle which limits the torque that can be applied to a jack so as to prevent overload and injury. The jack handle has a reduced cross-sectional portion between the handle and the jack engaging portion so that the handle will break off at the reduced cross-sectional portion, thus, preventing overloading of the jack. A portion of the handle which does not break off is provided with a jack engaging portion so that the broken portion of the jack can be removed and the second jack engaging portion can be inserted into the jack to lower it.
