Description

Technical Field

[0001] The utility model relates to the technical field of trekking poles, in particular to a trekking pole rod. Background Art

[0002] Trekking poles can bring many benefits to outdoor mountaineering activities, such as improving walking stability and reducing the burden on the legs. With the continuous improvement of trekking pole products, folding trekking poles have emerged, and the poles of the trekking poles can be folded or spliced. For example, a multifunctional detachable seat frame disclosed in Chinese utility model CN220256063U is composed of multiple poles, and the poles can be spliced ​​into a trekking pole or a seat, which can be folded and put away when not in use. In order to facilitate disassembly and assembly, the poles are designed to be plug-in and matched, and there is no locking structure. In actual use, it is found that when the trekking pole is stuck in the mud or in the cracks of the rocks, the subconscious action of the person is to hold the handle tightly and turn the trekking pole, which is similar to the action of twisting the trekking pole, in order to get the trekking pole out of the stuck position; but the pole at the bottom of the trekking pole is stuck and does not move. After twisting the pole at the top of the trekking pole, the plug-in between the poles is loose, and the pole at the top is easily pulled out upwards. Utility Model Content
