Arch clamp foot lifting apparatus |
摘要 |
Since a solenoid device generates the maximum drawing force at the final position of the retracting stroke of a plunger when it retracts into the solenoid device, the drawing force becomes so large at a position close to a pressing end position of a pressing member that energy is consumed than necessity, and the solenoid device is made large-sized. Accordingly, an arch clamp foot lifting apparatus of the present invention solved this problem by connecting a wedge-shaped block member to a plunger of the solenoid device and retaining an upper portion of the pressing member on a cam surface of a block member through a driven portion.
