The invention discloses a top holder capable of adjusting a fixed size. The top holder comprises an upper fixed rod, a lower fixed rod and a sliding mechanism for realizing the extension of the upper fixed rod and the lower fixed rod; and a fixing mechanism which is used for fixing the position of the lower fixed rod. According to the invention, a hand wheel beside the sliding mechanism rotates, a worm drives a gear connected with the worm to conduct transmission, the gear can drive a threaded rod to rotate, the threaded rod drives a threaded sleeve on the outer wall to slide on the threaded rod, therefore a sliding base above the threaded sleeve is driven to slide, the sliding base drives a connecting plate and a pressing plate above the device to slide, the lower fixed rod clamped between the pressing plate and the connecting plate is stretched through the stretching of a telescopic rod, the lower fixed rod drives the upper fixed rod to stretch together through a side connecting rod and an end connecting rod, stretching of the top holder in the length direction is achieved, the bearing capacity of the top holder is increased, and the using effect of the top holder is improved.
本发明公开了一种可调节固定尺寸的车顶架,包括上固定杆与下固定杆,所述车顶架还包括有:滑动机构,以实现上固定杆与下固定杆的伸长;固定机构,用于固定下固定杆的位置。本发明中,可以通过转动滑动机构旁的手轮,蜗杆带动与其相连的齿轮传动,齿轮即可带动螺纹杆转动,螺纹杆带动外壁上的螺纹套在螺纹杆上滑动,从而带动螺纹套上方的滑动底座滑动,滑动底座带动器上方的连接板与压板滑动,而被卡在压板与连接板中间的下固定杆通过伸缩杆拉长实现自身的伸长,下固定杆在通过侧连杆与端连杆带动上固定杆共同伸长,实现了车顶架长度方向的拉长,增加了车顶架的承载容积,提高了车顶架的使用效果。
