摘要：A locking mechanism has a threaded housing mounted in one member of a jack/vehicle asmbly. The housing has a locking pin which threadably moves through the housing and extends into a socket in the other member off center from the jack swivel point thus locking the jack in position and providing support for the trailer. The locking pin has a taper at its extension end which provides positive locking pin engagement with the socket and compensates for wear. Extension and retraction of the locking pin is performed by screwing the pin into or out of the housing. The locking pin is retained in the housing through the u of retaining pins thus obstructing disasmbly of the locking mechanism and possible loss of the locking pin in the field.
