(16) The control arrangement 30 is arranged to be provided between the picking tool 10 and the opening portion 212 of the disposable bag 20 to detachably hold at the picking portions 101 of the picking tool 10 at the bag layers 21 respectively. The opening 23 of the disposable bag 20 is controlled to be opened and closed by the picking tool 10 via the control arrangement 30. Particularly, when the picking tool 10 is actuated to move the picking portions 101 thereof away from each other, the opening 23 of the disposable bag 20 is opened up for receiving the ground waste in the storage cavity 22 of the disposable bag 20. When the picking tool 10 is actuated to move the picking portions 101 thereof toward each other for picking up the ground waste, the opening 23 of the disposable bag 20 is closed to retain the ground waste in the storage cavity 22 of the disposable bag 20. Then, the user can detach the disposable bag 20 from the picking tool 10 for disposing the disposable bag 20 with the ground waste received therein.

(17) As shown in FIG. 1, the two picking portions 101 of the picking tool 10 are configured for picking the ground waste. Accordingly, the picking tool 10 comprises a hand-held handle 11 and two picking claws 12 extended from two ends of the hand-held handle 11 to define the picking portions 101 at the picking claws 12. In one embodiment, the hand-held handle 11 comprises a U-shaped resilient frame coupling to the picking claws 12, such that the resilient frame is squeezed to move the picking claws 12 toward each other for picking up the ground waste and for closing the opening 23 of the disposable bag 20 at the same time. In other words, the picking tool 10 is embodied as a tong like picking tool. When the squeezing force is released from the hand-held handle 11, the resilient frame is bound to return back to its original form, such that the picking claws 12 is moved away from each other for opening up the opening 23 of the disposable bag 20. In other words, when a distance between the picking portions 101 of the picking tool 10 is minimized, the opening 23 of the disposable bag 20 is closed.
