Background technique

As a kind of fitness and entertainment equipment, the scooter is quite light and has excellent maneuverability, so it is popular among people. However, the ordinary scooter will take up more space when stored indoors due to the large and long body. The storage space is also not convenient to carry when going out. Therefore, the scooters on the market generally have folding devices, and the folding devices of different scooters are also different. For example, the applicant applied for on June 13, 2014. The announcement date is October 22, 2014, the announcement number is CN203888966U, and the utility model patent named "a folding mechanism of a scooter". The folding mechanism of the scooter includes a tilting tube, a front end of the pedal, a mandrel, and a lock. The tightening wrench, the pin shaft, the inclined tube have a round end, the hollow end forms a hollow cavity body, and further comprises a wrench, a transmission block, a transmission shaft, a first elastic device, a second elastic device, a card strip, a locking bar, and a pedal The front end is respectively provided with a long hole and a limiting hole, the wrench is arranged on one side of the front end of the pedal, the transmission block is arranged on the transmission shaft and is in contact with the clamping strip, and the first elastic device provides elasticity back to the transmission block. Force, the two ends of the locking strip are located in the long hole, the two ends of the strip are located in the limiting hole and are pressed into the first limiting slot by the transmission block, one end of the pin is connected with the locking wrench, and the other end is locked The strip is connected and the second elastic means is located between the locking strip and the mandrel. The folding mechanism of the scooter can realize the folding function of the scooter, and the locking bar and the strip are pressed tightly against the round end without gaps, so that during the driving of the scooter, The inclined tube and the mandrel do not sway up and down to prevent damage due to bumping during riding, which greatly prolongs the service life. However, when the folding mechanism of the scooter is folded, it is necessary to first pull the locking wrench with one hand, then pull the wrench with the other hand, and then use one hand to pull the inclined tube to rotate it, which is more complicated to fold. The operation is inconvenient.

technical problem
