Quick release pin for use as e.g. screw pin for assembling planar machine elements during construction of machine tools, has plates forming ramps that move away from each other during rotation of ramps relative to each other

摘要

The pin has a control and operation element (3) for controlling application/removal of a clamping mechanism (10) and clamping/unclamping parts between the mechanism and a clamping support. The operation element comprises an operation button (30), and a control rod (2) is mounted on an end (1b) of a pin body (1) by a return spring (21). A clamping plate (101) is arranged on the operation element. A pressure plate (102) is arranged on the rod. The plates are formed coaxial to each other and form ramps (103, 104) that move away from each other during rotation of the ramps relative to each other.
