Abstract
The invention relates to a telescopic friction bar comprising a front friction bar section and a rear friction bar section which are spliced together, wherein an inner joint is fixed at the front end part of the front friction bar section; an outer joint is fixed at the rear end part of the rear friction bar section; a guide bar mounting seat is fixed on the front friction bar section and fixedly provided with a guide bar in the direction identical with the length direction of the front friction bar section; a guide block is fixed on the rear friction bar section and is internally provided with a guide hole matched with the guide bar; and a detachable fastening device is arranged between the front friction bar section and the rear friction bar section. The invention overcomes the defect that the length of the traditional friction bar can not be adjusted and realizes that the length of the friction bar can be adjusted within a certain range to facilitate making up errors generated in the production process, thereby enhancing the error space for production and manufacture and improving the flexibility of installation and adjustment.
