The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device of the present invention has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool. ## Claims ### Claim 1 An adjusting device for adjusting the position of an attachment connected to a garden tool, comprising: a lifting device switched between a locking and a free position for adjusting the position of the attachment; and a locking mechanism for locking with the lifting device; wherein the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position; wherein the adjusting device further comprises an assisting mechanism arranged in a staggered mode with the lifting device, the assisting mechanism is provided with a retaining portion and a boosting portion, one end of the boosting portion is connected and positioned with the retaining portion, and the other end of the boosting portion is connected to the attachment. ### Claim 2 (depends on 1) The adjusting device according to claim 1, wherein the lifting device comprises a shaft assembly, a pedal assembly rotatably mounted to the shaft assembly 11, and a connecting portion for connecting the pedal portion and the attachment. ### Claim 3 (depends on 2) The adjusting device according to claim 2, wherein the pedal assembly comprises a pedal body and a pedal bracket connected to the pedal body, and the pedal body is fixedly connected to the shaft assembly via the pedal bracket. ### Claim 4 (depends on 2) The adjusting device according to claim 2, wherein the locking mechanism comprises a fixing portion, a locking portion and a reset mechanism connecting the fixing portion and the locking portion, one end of the locking portion is rotatably connected with the fixing portion, and the other end of the locking portion is provided with a toggle structure used for separate the locking mechanism from the pedal assembly, two ends of the reset mechanism fix to the fixing portion and the locking portion respectively. ### Claim 5 (depends on 4) The adjusting device according to claim 4, wherein the locking portion is located beside the pedal assembly, and the toggle structure is formed by the other end of the locking portion away from the fixing portion extending toward the pedal assembly. ### Claim 6 (depends on 4) The adjusting device according to claim 4, wherein the locking portion is provided with a holding protrusion toward the pedal assembly, and the pedal assembly is provided with a holding member corresponding to the holding protrusion on a side thereof closed to the locking portion. ### Claim 7 A garden tool, comprising: a driving body;
