Provided is a device for fixing hydraulic piping to prevent the hydraulic piping from sliding down even when the bolt for coupling a clamp which fixes the hydraulic piping is loosened by the vibration generated during operation. The support assembly may move along a rail and collect articles thereagainst which are moving at a rate greater than the support assembly. In this manner, the present invention prevents the latch portion from randomly moving its pawl away from the gear pulley while being subjected to an inappropriate pulling and smoothly draws the strands for interlacing them into a braiding fabric, thus increasing the braiding efficiency and quality. The determination module determines one or more second users related to the first user based at least in part on the user identification data. Since the burr formation surface has a larger surface area than a rounded surface, a large bonding area is obtained. A random module can enable random retrieval of various dog barking sounds from memory for processing.
