Abstract

The present invention provides a structural improvement of a climbing and mountaineering machine, mainly because the top of the base is provided with an extension groove, which allows the sliding rod of the handrail unit to extend out for sliding movement, thereby reducing the length of the base frame. The material cost of the length can also reduce the telescopic sliding area of the sliding rod of the armrest unit relative to the inside of the base, so as to effectively reduce the sliding noise generated between the armrest unit and the base; then the external magnetic damping device The damping adjustment knob is used to rotate and stretch the damping adjustment cable to control the pivot angle of the slot-shaped magnet control base and the relative position between each magnet block and the magnetic conductive disc set in the slot-shaped space. The size of the magnetic damping sensing area can not only better control the damping intensity of the external magnetic damping device, but also reduce the cost of the conventional internal magnetic magnetron due to its more complex materials and structure.
