Origins

Now that the trekking poles are becoming more and more mainstream, the outer locks are not perfect. Like the inner locks, they also have their own structural shortcomings. For the most insightful analysis, please refer to Xi'an Lao T’s Several Alpenstocks. Theoretical analysis of the stability of the internal lock and external lock method Why is there not a double lock trekking pole, that is, the internal lock of the bulge can be used, or the external lock of the lock can also be used to concentrate the advantages of both locks on one On the stick. Such double locks are locked at two points in each section, and there is a certain distance between the lock points. This can almost eliminate the phenomenon of jitter due to the difference in the inner and outer diameters of the two rods, and whether they are static pressure in the longitudinal direction or in the transverse direction. The ability to transmit shear force will be doubled. If you use an ultra-light rod to transform it, you can also have a lighter weight with the above advantages. A light, strong, stable, and convenient trekking pole sounds too tempting. It has caused my DIY interest!
