PURPOSE:To make a space for machinery small by providing double built-in spindles which act by means of compressed air from a cylinder tube and uniting cylinders into a single body. CONSTITUTION:By means of compressed air admitted through a compressed air infusion port 9, and also because a spring 6 has less elastic force than a spring 7, a spindle 5 advances to its maximum and strikes against a catching part 10 of a spindle 2, which is pushed forward. When compressed air is shut out from infusion, both spindles 2, 5 are restored to their former condition. In such a configuration, since an operational distance of a spindle may be doubled and cylinder may be united into a single body even with a short cylinder tube,a space for machinery may be lessened. |
