Abstract

The utility model relates to a clamping mechanism for a foldable elliptical machine. The clamping mechanism comprises a pedal pipe, a crank connected with a rear frame and also connected with the pedal pipe through a clamping jaw, a base fixed to the pedal pipe, a sliding block matched with the base and moving relative to the base, and a button sleeved in the sliding block, wherein the clamping jaw is arranged at the front end of the pedal pipe; the button is rotationally connected onto the base; the lower part of the sliding block is movably connected onto the base; a control device for controlling the sliding block to slide is arranged between the sliding block and the base; and a limiting device for controlling the button to rotate and a limiting groove for controlling the sliding block to move are arranged on the button. The clamping mechanism has the advantages as follows: when the clamping mechanism is mounted, the movement of the sliding block is limited through the limiting groove and the limiting device arranged on the button, so that the pedal pipe is fixed with the crank; and when the clamping mechanism is dismounted, the button is pressed down by the palm only, and the sliding block is pulled back by the thumb at the same time, so that the pedal pipe can be taken down, the mounting or dismounting operation is simplified, the labor amount is reduced, and the using effect is good.
