Abstract
The utility model provides an ideal telescoping portable crow bar and belongs to the electric power overhaul technical field. The telescoping portable crow bar is characterized by comprising a wedge-shaped outer end arm, a cone-shaped outer end arm and an inner connection arm, wherein the cone-shaped outer end arm is installed at one end of the inner connection arm through an inner screw thread and an outer screw thread of the inner connection arm, and the wedge-shaped outer end arm is installed at the other end of the inner connection arm through the inner screw thread and the outer screw thread of the inner connection arm. When a short crow bar is needed, the inner connection arm is screwed into the wedge-shaped outer end arm and the cone-shaped outer end arm, after the inner connection arm is in place, a positioning groove can be seen from an approaching hole, and then the short crow bar can be used after a locking screw is screwed into the positioning groove. A long crow bar can be obtained with an opposite method. Compared with the prior art, the telescoping portable crow bar has the advantages of being simple in structure, convenient to carry and use, energy-saving, fast to realize, and the like.
