精确扭力限定扳手
摘要：
本发明公开了一种精确扭力限定扳手，包括一把手、一扳手杆和一扭力限定机构；所述把手内部形成安装槽，所述把手底部形成与所述安装槽连通的一安装孔，所述扳手杆第一端通过所述安装孔限位于安装槽内；所述扭力限定机构安装于所述安装槽内，且所述把手通过所述扭力限定机构与所述扳手杆传动连接，所述扳手杆第二端形成扳头并自所述安装孔伸出。由于采用了本发明的一种精确扭力限定扳手，具有精确度高、扭力可调节范围大、结构简单、成本低、适用范围广和使用环节无需保养、后期使用成本低的优点。
摘要（英）：

The invention discloses a precise twisting force limiting wrench which comprises a handle, a wrench rod and a twisting force limiting mechanism. A mounting tank is formed in the handle. A mounting hole communicating with the mounting tank is formed in the bottom of the handle. The first end of the wrench rod is limited in the mounting tank through the mounting hole. The twisting force limiting mechanism is mounted in the mounting tank. The handle is in transmission connection with the wrench rod through the twisting force limiting mechanism. A spanner is formed at the second end of the wrench rod and stretches out of the mounting hole. The precise twisting force limiting wrench has the beneficial effects of being high in precision, wide in twisting force adjustable range, simple in structure, low in cost, wide in application range, free of maintenance in use links and low in subsequent use cost.
