Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a clamp used during rock climbing. More particularly, the present invention relates to a spring-type clamp for rock climbing, which makes it possible to install a climbing protection piece more safely using a length-adjustable pole so that the climbing protection piece can be installed in a preferable place at a distance when climbing a section where it is very dangerous to install the climbing protection piece during the rock climbing.

2. Background Art

In general, rock climbing is performed in a manner that a leader climbs a rock as hooking a rope on a vertical rock wall, and then a second climbs the rock as tying his/her body with the already installed rope.

At this time, in order to avoid danger and to perform climbing more safely, the leader may hook a carabiner on a bolt hanger that is installed on the rock wall to pass a rope through the carabiner, or hook a climbing protection piece between gaps to reduce a fall distance.

The climbing protection pieces (carabiner, cam set, nuts, hooks, etc.) are currently used in climbing, and such climbing protection pieces are put on belts that the leader and the second wear on their bodies.

However, such climbing protection pieces have a short length of 30 cm or less, and thus can be installed or withdrawn only in positions that the leader and the second can reach with their hands.

Accordingly, if a space for installing the climbing protection piece therein is not secured in the position that the leader or the second can reach with his/her hand, it is difficult to install the climbing protection piece having the short length in the position, and this may cause fall accident to occur.
