ANGLE ENGAGEMENT IMPACT RESISTANCE SYSTEM

摘要

To provide an angle engagement impact resistance system.SOLUTION: A buffer device 60 includes a support defining a housing inserting a pivot module, a receiving stone, a holed stone, a spring ring and an insertion system incorporating the spring ring, where the insertion system includes a peripheral shoulder part 48, a circular groove 50 defining a holding area is formed below the peripheral shoulder part 48, the spring ring includes at least one fastening part 52 and at least one first notch part 54 communicating with the circular groove 50 provided in the peripheral shoulder part 48 on the outer peripheral part, thereby the spring ring is matched so that the fastening part 52 is engaged with the inside of the corresponding first notch 54 in order to make the fastening part 52 slidable inside of the circular groove 50 below the peripheral shoulder part 48, then the spring ring is only pivoted and at least one second notch 62 machines the inside of the peripheral shoulder part 48, thereby the fastening part 52 is engaged with the inside of the second notch and secures angle pivot engagement of the spring ring.SELECTED DRAWING: Figure 6B
