Abstract
The invention discloses a tubular bus-bar fixing fitting. According to the tubular bus-bar fixing fitting, adjusting rollers are assembled on the wall of a locating hole, wherein each adjusting roller rotates around the axis extending in the direction of the tangent to periphery. Each adjusting roller is provided with a contact portion which is located in the locating hole and in contact with the peripheral surface of a tubular bas-bar. When the tubular bus-bar fixing fitting is used, the adjusting rollers can guide the tubular bus-bar to move in the axial direction of the locating hole through rotation of the adjusting rollers, and therefore the effects that the tubular bus-bar is loosened or fixed and it is guaranteed that the tubular bus-bar can be flexibly adjusted are achieved. In addition, due to the fact that during adjustment, the adjusting rollers cannot influence length adjustment of the tubular bus-bar, the problem that in the prior art, a fixing fitting for loosening and fixing influences the movement adjustment of the tubular bus-bar severely is avoided, the adjustment range of the tubular bus-bar is expanded, and the flexibility of adjustment of the tubular bus-bar is improved.
