摘要： PURPOSE:To prevent breakage and damage by detaching a movable block which sandwiches an optical fiber by means of a spring pressure from a stationary block in the stage of removing the same thereby expanding the space between both blocks and permitting easy and safe installation and removal to and from a slip holder. CONSTITUTION:A pressing spring 20 is simply in contact with a movable block 13 and a vertical plate part 22 and does not act compressive force while retaining members 7a, 7b for optical fibers are in a horizontal positon. Therefore, only the repulsive force of a spring 15 acts on the block 13, and an optical fiber 1a is grasped by means of grasping members y3, y4 with a suitable grasping force. If the members 7a, 7b are lifted, the plate part 22 enters the inside of an opening 24 and compresses the spring 20, and at the point of the time when the repulsive force of the spring 20 overcomes the repulsive force of the spring 15, the block 13 is detached from a stationary block 14, and the space between the members y3, y4 is substantially expanded while a horizontal plate part 21 is in a horizontal position, thus allowing the easy removal of the fiber 1a.
摘要翻译：目的：为了防止破坏和损坏，拆卸可移动块，通过在移除固定块的弹簧压力夹住光纤，从而扩大两块之间的空间，并允许容易且安全的安装和拆卸和一个滑架。构成：按压弹簧20与可移动块13和垂直板部22简单地接触，并且不起作用力，而用于光纤的保持构件7a，7b处于水平位置。因此，只有弹簧15的排斥力作用在块13上，并且通过抓握构件y3，y4以适当的抓握力来抓握光纤1a。如果构件7a，7b被提起，则板部22进入开口24的内部并压缩弹簧20，并且在弹簧20的排斥力克服弹簧15的排斥力的时刻，块13与固定块14分离，并且构件y3，y4之间的空间大致膨胀，而水平板部21处于水平位置，从而容易地除去纤维1a。

摘要： PURPOSE:To prevent swing or movement due to wind pressure and vibration, and to hold an optical fiber securely in an optional step at its jointing time by arc welding by providing a device for giving a pressing force against the fiber pressing member. CONSTITUTION:The optical fiber retaining member 20 is lifted, a movable block 13 is released from a fixing block 14, the optical fibers 1a, 1b are laid between pinching members x1-x4, y1-y4, and they are pinched with a spring 15. When the optical fibers 1a, 1b are necessary to be tightly held nonslippably, they are held by turning on a switch 27 to induce an induction magnetic field in an electromagnetic coil 25, attracting a magnetic body 22 in the direction of the coil 25, and as a result, pressing both fibers 1a, 1b to both blocks by these attractions. Since the device for giving a pressing force to the member 20, and another force can be given to each fiber besides the pinching force of each pinching member (x), (y), the fibers can be held at an optional step during the jointing operation by arc welding.
