Detailed description of the invention

As shown in the figure: the invention relates to a bicycle with an elastic supporting foot, which comprises a control system and the elastic supporting foot. The control system comprises a left handle (1) and a right handle (2) on the bicycle faucet, tension steel ropes (16) and (17) on the handles, a driving wheel (4) connected with the left tension steel rope (17), a driven wheel (5), a driving wheel (3), a bearing and a connecting rod (7). The right tensile steel rope (16) is connected with the blocking piece (8), the blocking piece is respectively provided with a blocking piece (9), a pulley (10) and a spring, and the support leg (11) body is arranged in the side pipe of the goods shelf.

The left and right handles (1, 2) are respectively connected with a plurality of synthetic steel ropes with the length of 91 cm, the left tension steel rope (17) is connected with the driving wheel (4), when the left handle (1) is pulled, the driving wheel (4) moves forwards by 2.5 cm to drive the driven wheel (5) to rotate 360 degrees, the driving wheel (3) which is connected with the driven wheel (5) by the same connecting rod rotates for a circle, the steel rope on the driving wheel (3) is lifted upwards by 38 cm, the blocking piece (9) on the blocking piece (8) pops up to block the falling of the supporting foot (11), after the left handle (1) is loosened, the left handle (1) is driven to return to the original point by the force of the spring, the spring of the driving wheel (4) pulls the driving wheel (4) for 2.5 cm, the driven wheel (5) returns to the original point, the driving wheel (3) also rotates for 360 degrees, because the body of the supporting foot (11) is placed at a high position by the blocking piece (9), the steel rope at the top end of the supporting foot (11) is in a loose state. The right handle (2) is pulled, the steel rope connected with the right handle (2) is branched and then is branched into four branches, twelve blocking pieces (9) on four groups of blocking pieces (8) are tensioned respectively, the supporting leg is popped out of the side tube by a pressure spring (13) at the top end of the supporting leg, after the right handle (2) is loosened, the right handle (2) is returned to the original position by the spring, the right pulling force steel rope (16) is loosened, the blocking pieces (9) are pushed out by the spring on the blocking pieces (8), and the popped supporting leg (11) is locked. It should be noted that: when the supporting foot (11) is contracted again, the right handle (2) is pulled firstly, the blocking piece (9) is retracted in advance, and then the left handle (1) is pulled, so that the supporting foot (11) can smoothly return in the side pipe.

Two blocking pieces (9) are downwards designed on one group of blocking pieces (8) of the invention, so that when the road surface is uneven, a second fulcrum can be found by the foot support (11) to prevent unbalance and danger.
