Description

Technical Field

[0001] This utility model relates to the field of motion cylinder technology, specifically a bidirectional four-way motion cylinder. Background Technology

[0002] The pressing of probe fixtures is becoming increasingly precise and standardized. This requires that the pressing mechanism be universal and easy to disassemble. The product connectors must be compatible with both upward and downward movement. Furthermore, the pressing mechanism must not be displaced during movement. In special circumstances of power on / off (gas), the cylinders should be reset in sequence to prevent damage to other workpieces.
