摘要： An apparatus, used for holding a coupling pin (15) at a desired position in a pin-coupled structure regardless of a relative movement of two or more pin-coupled parts in the structure, is disclosed. This pin holding apparatus has two pin holding blocks (3), with an elastic member (5) interposed between the two pin holding blocks, and is inserted into a pin slot (17) with the two holding blocks radially compressed by an external force to reduce the outer diameter of the apparatus. The apparatus elastically expands in the pin slot (17) due to the restoring force of the compressed elastic member (5) when the external force is removed from the apparatus, thus being set in an annular groove formed on the inner surface of the pin slot and holding the pin (15) at its desired position in the pin slot. The pin holding apparatus is easily set in and removed from the pin slot (17). This pin holding apparatus also has an elastic cushion (11), which is positioned at the junction of the pin (15) and the pin holding apparatus, thus almost completely preventing a breakage of the pin.

摘要翻译： 公开了一种用于将联接销（15）保持在销耦合结构中的期望位置而不管结构中的两个或多个销耦合部件的相对运动的装置。 该销保持装置具有两个销保持块（3），弹性构件（5）插入在两个保持块之间，并插入到销槽（17）中，两个保持块通过外力径向压缩 减小设备的外径。 当外力从装置中取出时，由于压缩弹性构件（5）的恢复力，设备在销槽（17）中弹性膨胀，因此被设置在形成在销槽内表面上的环形槽中 并将销（15）保持在销槽中的期望位置。 销保持装置容易地设置在销槽（17）中并从销槽（17）移除。 该销保持装置还具有位于销（15）和销保持装置的接合部处的弹性缓冲垫（11），从而几乎完全防止销的破损。

摘要： The present invention relates to a hydraulic breaker and, more specifically, to a hydraulic breaker provided with an automatic lubricant supply structure. Particularly, the present invention relates to a hydraulic breaker which automatically supplies a lubricant without a separate hose by using a hydraulic oil and which is provided with an automatic lubricant supply structure that is built into a main body of the hydraulic breaker and can be used without a separate external component.
