Detachable hollow bolt

The detachable hollow bolt comprises a bolt body, a cavity is formed in the inner wall of the bottom of the bolt body, a supporting rod is fixedly connected to the interior of the cavity, a connecting rod is fixedly connected to the upper surface of the bolt body, and a rotating piece and an opening are fixedly connected to the outer surface of the connecting rod. The outer surface of the connecting rod is in threaded connection with a fixing piece, a groove is formed in the upper surface of the fixing piece, and the upper surface of the connecting rod is fixedly connected with a limiting rod. By means of the structure, the bolt and the fixing piece can be detached, the bolt can be fixed, meanwhile, when the bolt is rusted, the fixing piece and the bolt can rotate respectively, and twisting is facilitated. 本实用新型公开了一种可拆卸的空心螺栓，包括螺栓，所述螺栓的底内壁设置有空腔，所述空腔的内部固定连接有支撑杆，所述螺栓的上表面固定连接有连接杆，所述连接杆的外表面固定连接有转动片，开口，所述连接杆的外表面螺纹连接有固定片，所述固定片的上表面设置有凹槽，所述连接杆的上表面固定连接有限位杆。通过上述结构，可以螺栓与固定片进行拆分，可以对螺栓进行固定的同时可以在螺栓出现锈蚀时，固定片与螺栓进行分别转动，便于扭转。
