Some people think that the hand can bear more weight for the climber, so the hand must be large. However, this is not necessary. Most of the hands on the straight wall are used to master the balance. The contact force between the fulcrum and the hand will become the key. But no matter what, do not use too much force in your hands when you grab points. Instead, you must relax your hand and use minimal force to grab points, otherwise you will lose your arm strength quickly. The fulcrum on the rock wall has many shapes. There are dozens of kinds of common fulcrums. The climber should be familiar with the shape of these fulcrums and know where and how to exert force on different fulcrums. According to the position and direction of the protrusions and depressions on the fulcrum, climbing mainly includes the following climbing techniques:
Hold tight
When a finger grabs a ridge of a fulcrum, it usually grips it tightly. But many times, some fulcrums can hold it with the palm of your hand without relying solely on the strength of the fingers, and the grip of the entire palm can also increase the stability of the grip.
Open grip
If the edge of the fulcrum or a small hole in some points can support the second joint of the finger, the hand can lie flat on the rock surface, so that the hand can be opened, the fingers are close together, and the finger is in full contact with the fulcrum, the whole palm Do not hold the fulcrum. In this action, the thumb is generally small, but if the fulcrum is tilted, the thumb can pinch the point with the other fingers. In general, if the fulcrum is round, the gripping method is the best choice.
Hold
When the hand encounters a relatively small fulcrum, when the four fingers of the hand can catch the fulcrum when they are close together, the thumb can press the index finger to cover the fulcrum and perform the squeezing motion. When doing the squat, it is not necessary to avoid the finger. Stress and pulling force to avoid injury to the fingers (When the palm is facing upwards, grabbing the soil, you need to use anti-spasmodic movements. This kind of grabbing is often used to maintain balance, it is through the hands and hands or hands and feet The counter-force between
Grip
The curved grip is the palm of the hand bent, four fingers close together, the thumb pressing on the index finger, the outer edge of the palm of the hand holds the fulcrum, because the strong force of the thumb, can control the hand shape, so this grip is not only powerful, but The wind gives the rest of the fingers a good chance to relax. In fact, the forearm can be relaxed by bending the fulcrum of the wrist. Therefore, this kind of wrist gripping movement is a good rest posture, generally in the small ball-like protruding fulcrum point and dot, the application of this kind of action many.
Pinch
When the shape of a fulcrum does not have a holdable edge and can only rely on the friction of a finger, it is necessary to use a pinching action. In general, the direction in which the thumb is pinched is relative to the direction the finger is grabbing, but sometimes there are points that can hold your thumb against the side of the fulcrum, and the pressure side always has four fingers.
Side pull
The basic technical point of the lateral pull is to make the lateral rock wall of the body contact the rock wall with the body's opposite hand and foot. The other leg is straightened to adjust the balance of the body. The body is lifted by one leg and the upper point is grasped. The action is mainly used at the site when the over-elevation section and the support sand point are arranged close to a straight line.
Hole Method
In the natural rock wall, there are often many small holes in the rock wall, and many “holes†often appear in modern rock climbing competitions. The size of the climbing hole can range from one narrow gap to one or two fingers. The big hole that the entire hand can reach into, and when it comes to grasping these holes, first of all feel the hole from the inside and find the deepest part of the grasp. Pointing is the hardest point in all holes. If you accidentally pull the fingers, you can pull the muscles of the fingers. If the single finger is in the vertical direction, you can use the middle finger to hold the index finger to increase the stability of the finger points. The sizes are all different, and there may be multiple grasping methods for the same fulcrum. However, it is necessary to rapidly select the best one. It is also necessary to master and use it flexibly through a large number of exercises. The force of the fingers is very important in the use of climbing techniques. Usually it can be practiced by means of bracing, pull-ups, hanging guides, and lifting heavy objects.

PP plastic, also known as polypropylene plastic, is another fine resin varieties, following the development of nylon, which is a semi-crystalline materials, the advantage is obvious, with excellent mechanical properties and heat resistance, with a high not hydrophilic sex, almost non-absorbent. The disadvantage is poor low temperature impact resistance, easier to aging. However, for comparison PE plastic having a higher melting point.
PE plastic is polyethylene plastic, its corrosion resistance and electrical insulation are very strong. Rigid hardness and strength are relatively high, and the same PP plastic, it also very small water absorption.
Polycarbonate (referred PC) is a polymer molecular chain containing a carbonate group, an ester group according to the structure can be divided into aliphatic, aromatic, aliphatic - aromatic and other types. Which due to the aliphatic and aliphatic - aromatic polycarbonate lower mechanical properties, thereby limiting its application in engineering terms. Currently, only the aromatic polycarbonate obtained industrial production. Due to the special nature of the polycarbonate structure, it has now become the top five fastest growing engineering plastics in general engineering plastics.
