Claims

[Scope of Claim for Utility Model Registration] ■ Common for a multi-stage planetary gear device connected to a drive device, in which an outer socket with a nut engagement hole is rotatably fitted into an inner socket with a bolt tip engagement hole. The outer socket is connected to the internal gear at the final stage, the inner socket is connected to the final stage planetary gear support frame, and the bolt tip is sheared by the contradictory rotational forces acting on both sockets. A bolt tightening tool in which an idler wheel 16 is connected to the planetary gear set of the first stage to match the rotational direction of the input shaft 14 to the sun gear of the gear set with the rotational direction of the internal gear. (2) The bolt tightening tool according to claim 1, wherein the drive device is a manual handle connected to a planetary gear device via a one-way rotation transmission device. (2) The bolt fastener according to claim 1 or 2, wherein the planetary gear device is of a two-stage type. ■ The scope of the utility model registration claim that the planetary gear device of any stage is composed of a sun gear, an internal gear, a planetary gear that meshes with the internal gear, and an idler that meshes with both the planetary gear and the sun gear. The bolt fastener according to any one of items 1 to 3. ■ The first stage planetary gear device consists of a sun gear, an internal gear, a planetary gear that meshes with both gears, and an input gear that meshes with the sun gear and drives the gear. The bolt fastener according to any one of items 1 to 3.
