The telescopic crowbar comprises a crowbar fixing rod, the upper portion of the crowbar fixing rod is connected with a telescopic rod assembly, and the lower portion of the crowbar fixing rod is connected with a prying head assembly and a chisel rod assembly; the chisel rod assembly comprises a chisel rod body, a chisel rod conical head is arranged at one end of the chisel rod body, a chisel rod connecting piece is arranged at the other end of the chisel rod body, a positioning piece is arranged on the crowbar fixing rod, and the chisel rod connecting piece is connected with the positioning piece. Through telescopic adjustment of the overall length of the crowbar, operation and use of the crowbar in roadways with different heights are more convenient, a supporting fulcrum is formed on a construction plane, and due to the square structures of the right side supporting block and the left side supporting block, slipping is prevented, stones are pried more easily, rapid fixing of the conical head chisel rod is achieved, and the working efficiency is improved. And then, the conical head chisel rod is inserted into the stone for chiseling and crushing, so that the functionality of the crowbar is increased, and the crowbar is more convenient to use.

    本发明涉及一种用于矿山巷道清理浮石的可伸缩撬棍,包括撬棍固定杆,撬棍固定杆的上部连接有伸缩杆组件,撬棍固定杆的下部连接有撬头组件和凿杆组件;凿杆组件包括凿杆本体,凿杆本体的一端设有凿杆锥头、凿杆本体的另一端设有凿杆连接件,撬棍固定杆上设有定位件,凿杆连接件与定位件连接。本发明通过撬棍整体长度的伸缩调节,更方便不同高低巷道内的撬棍操作使用,在施工的平面上形成一个支撑的支点,并且右侧支撑块和左侧支撑块的方形结构,防止了打滑,更轻松的对石块进行撬动,实现了锥头凿杆的快速固定,然后便可通过锥头凿杆插入石块中进行凿动粉碎,增加了撬棍的功能性,更方便撬棍的使用。
