发明名称 Gear grasping device
摘要 A gear grasping device includes a main body, a first jaw, a second jaw, and an adjustment means. The main body is provided with a curved portion accompanied with an opening. The first jaw and the second jaw are disposed on the main body. The opening is arranged between the first jaw and the second jaw. By the adjustment means, position of the first jaw is changeable for adjusting a jaw span between the first jaw and the second jaw. Therefore, the gear grasping device is fit for sizes of gears, and is operation-friendly.

主权项 1. A gear grasping device for grasping a gear, comprising: a main body, comprising a handle, a curved portion and a block, the handle having a longitudinal direction, the curved portion being disposed on one end of the handle, the curved portion being formed with an opening, the block being connected to an outer face of one end of the curved portion away from the handle; a first jaw, disposed on the handle, the first jaw having an extension direction parallel to an axial direction defined by the opening of the curved portion, the first jaw being adjustable linearly along the longitudinal direction; a second jaw, disposed on the main body, the curved portion being entirely located between the first jaw and the second jaw; wherein a bottom surface of the first jaw faces toward a top surface of the second jaw, so that a jaw span is defined by the first jaw and the second jaw, along the longitudinal direction a greatest dimension of the curved portion is less than a minimum jaw span; and an adjustment means for adjusting position of the first jaw between a first position and a second position, so that a size of the jaw span is adjustable; wherein the block has a through slot extending linearly in a direction perpendicular to the longitudinal direction and the axial direction defined by the opening of the curved portion, the second jaw is adjustable along the through slot to be partially beyond a free end of the curved portion in the direction in which the through slot extends; and wherein the first and second jaws are entirely located outside of the opening of the curved portion.
