摘要： The present invention provides an improved release mechanism for clamping tools where problems of thread slipping due to worn out thread can be reduced by the structure of a plunger with a small diameter section and the engagement of the thread shaft is made more secure by the cam action on account of the shape of the plunger.

摘要： The present invention provides an improved release mechanism for clamping tools where problems of thread slipping due to worn out thread can be reduced by the structure of a plunger with a small diameter section and the engagement of the thread shaft is made more secure by the cam action on account of the shape of the plunger. A protrusion extends from a push button on a top portion of the half-threaded nut. Threads are formed on an upper portion of the hole for engaging the threaded shaft. The middle portion of the plunger is made to have a section of small diameter allowing the protrusion to be pushed downward in a normal position and allowing the protrusion to rely on the resilient power of the helical spring to push it upward into the small diameter section.
