<p>A pull rod bag with telescopic wheels (1) and a wheel telescoping operation mechanism, the wheel telescoping operation mechanism comprising: two pushing parts (9), the front end of each pushing part (9) can be connected with the rotating shaft (7) of a corresponding telescopic wheel (1); a transmission unit, comprising a transmission rod (8), two ends of the transmission rod (8) are connected with the rear end of a corresponding pushing part (9), respectively, such that the rotating shaft (7) of the corresponding telescopic wheel (1) can be driven to move back and forth in a mounting groove (45) when the transmission rod (8) moves up and down; and two locking parts (3), each locking part (3) can cooperate with a corresponding pushing part (9) so that the rotating shaft (7) of the telescopic wheel (1) connected with the corresponding pushing part (9) is locked in a folded state or an unfolded state. The pull rod bag with telescopic wheels (1) comprises a base (4) and two telescopic wheels (1) arranged on two sides of the base (4), respectively, as well as the above wheel telescoping operation mechanism arranged on the base (4). The pull rod bag with telescopic wheels (1) and the wheel telescoping operation mechanism are simple and reliable in structure and convenient to operate.</p> |
