Structure of trekking pole

1, handle

Handle is usually made of EVA, rubber, cork, plastic and other materials, and each material has the following characteristics: EVA: comfortable grip, full and elastic, not affected by seasons, and the material has the function of absorbing sweat; Rubber: full grip, hard and easy to crack in winter, no sweat absorption function, easy to slip in summer; Cork: It has a full grip, is not affected by seasons, and has the function of absorbing sweat, which is easy to wear and peel; Plastic: poor grip, easy to crack in winter and easy to slip in summer, but low cost, cheap and convenient. 2. Wrist band

This is the most important part to consider when buying trekking poles. Because the mutual transmission between trekking poles and users' physical strength is mainly through wristbands, we should consider whether they have the following characteristics when choosing high-quality wristbands: the middle of the wristband is wide and the sides are narrow, which can prevent hand wringing; The wrist strap adjusting buckle is arranged at the joint with the trekking pole, which is not in contact with the hand to prevent hand injury; The inner side of the wristband is made of suede anti-friction material, which effectively protects the skin contacted by the wristband. 3. Pillar

The materials of pillars are usually aluminum alloy, carbon fiber, titanium alloy, wood, steel and other materials, among which aluminum alloy and carbon fiber are the most widely used, and several materials have the following characteristics: aluminum alloy: durable, cheap, heavier than carbon fiber and titanium alloy, and easy to corrode; Carbon fiber: light weight, good elasticity and toughness, high strength ratio, corrosion resistance and high price; Titanium alloy: light weight, good elasticity and strength, corrosion resistance and high price. 4. Locking system

Locking system is the core safety component of trekking poles, and 90% of trekking pole problems are caused by locking system failures. Low-priced trekking poles are generally made of common plastic parts that are easy to deform, while high-end trekking poles are made of high-hardness engineering plastics (crystal plastics) through precise cutting. For example, the advanced locking system recognized by the industry, the Flicklock joint locking system independently developed by Black Diamond/Black Diamond, the second generation locking system of Robinson's patented SLS, and the 3LS safety locking system of Wildview/ Wade, etc. At the same time, the aluminum trekking pole will be equipped with a shock absorption system together with the locking system. As a spring component, the shock absorber system can effectively buffer the impact force and reduce the pressure on the knee when going downhill, but because the spring absorbs the thrust when going uphill, it will consume extra physical strength when walking for a long time. In addition, the spring parts with poor material are easy to rust, break and slip, which will lead to the locking system locking or failure. The trekking poles made of carbon fiber and titanium alloy have good elasticity and toughness, and the balanced shock absorption effect can be achieved without setting a shock absorption system. 5. Mud tray.

The mud tray can prevent the trekking poles from sinking into the mud, but there are many thorns and shrubs in the climbing environment, and the mud tray will hinder the convenience of action, so pay attention to the quick disassembly of the mud tray to avoid trouble. 6. Staff tips

The rod head is made of rubber head, iron, carbon tungsten steel, etc. Carbon-tungsten steel is the hardest, the most expensive, and the rubber head is the cheapest, but it can't cope with rugged outdoor terrain and its wear resistance is not as good as that of carbon-tungsten steel head. The common patterns on the tip of the staff are net pattern, diamond pattern and plaid pattern. Among them, the diamond pattern has the best slip resistance and penetration.
