Self-locking guard bar for power equipment

The utility model relates to power transmission and distribution engineering, in particular to a self-locking guard bar for power equipment. The self-locking guard bar comprises a guard bar column (1) and a tubular column seat (3), the lateral side of the tubular column seat (3) is provided with a double-turning slot (5), one end of the double-turning slot (5) extends to the upper end face of the tubular column seat (3) to form a fracture while the other end of the tubular column seat (3) forms a limiting pit (6), and the slot between the first turning and the second turning of the double-turning slot (5) is an uptrend skewed slot; a radial pin (2) in clearance fit with the double-turning slot (5) is arranged on the lower portion of the guard bar column (1); the guard bar column (1) is fittingly inserted into the tubular column seat (3), and the radial pin (2) is positioned in the limiting pit (6). The self-locking guard bar for the power equipment is reasonable in design and simple in structure, self-locking
