[0024] When the front handle 4 is held to operate the device, a wrist will hold the front handle 4 and press it down, thereby driving the fixed plate 51 fixedly connected thereto to slide along the inner cavities of the two T-shaped slide grooves 31, during which the sliding plate 81 will be driven to move through the transmission plate 1 53.

[0027] When the front handle 4 moves downward, the fixed plate 51 fixedly connected thereto will drive the two rotating sleeves 101 to compress the corresponding spring 103, and at the same time the rotating member 102 will slide into the corresponding inner cavity of the rotating sleeve 101 to contract, thereby buffering the vibration force suffered by the wrist holding the front handle 4.
