Problems solved by technology
At present, the general chest ascender is relatively rough, the precision is not enough, the performance is poor, and it often does not play a protective role.
Moreover, when the angle of pushing up the ascender is too large in actual use, the rope may jump out of the ascender, thereby causing the danger of the user's ascender falling off the rope
In addition, the ordinary chest ascender is made of ordinary aluminum, which is not hard enough and is prone to wear and tear. There are no sewage discharge slots and cleaning grooves on the grab rope cam, which is inconvenient to clean

The invention discloses a chest-type ascender, which comprises an ascender body, a rope grabbing cam and a control handle, wherein two sides of the ascender body are respectively bent to the same side to form a first notch and a second notch which is used for penetration of a climbing rope; the openings of the first and second notches are opposite to each other; one end of the rope grabbing cam is hinged in the first notch, and the other end of the rope grabbing cam is a movable end; the movable end can be screwed from one side of the second notch and is pressed against the rope grabbing cam which penetrates through the second notch; a positioning boss which is used for preventing the rope grabbing cam from sliding out of the other side of the second notch is formed on the ascender body between the first notch and the second notch; the control handle is used for controlling the rope grabbing cam to be screwed into the second notch; and one end of the control handle is hinged with an outer wall of the first notch, and the other end of the control handle is hinged with the movable end of the rope grabbing cam.
Description
technical field [0001] The invention discloses a falling protection tool for climbing, in particular to a chest ascender. Background technique [0002] The ascender is a kind of rope climbing tool used when climbing a rock wall, wall or obstacle without a safe fulcrum, and it is widely used in fields such as fire rescue and outdoor rock climbing. Most of the ascenders currently used are rope-grabbing ascenders. This rope-grabbing ascender uses a combined structure of a rope-grabbing component and a chute. . There are three types of ascenders: hand ascenders, chest ascenders and foot ascenders. At present, the general chest ascender is relatively rough, with insufficient precision and poor performance, and often does not have a protective effect. And when the angle of upwardly pushing the ascender is too large in actual use, the rope may jump out of the ascender, thereby causing the danger of the user's ascender falling off the rope. In addition, the ordinary chest ascend...
