Handle lever limiting crankshaft

The invention provides a handle lever limiting crankshaft, which is characterized by comprising a shaft body. The shaft body is of a straight structure provided with a fixing hole, a stroke groove isformed in the top of the shaft body, a limiting groove is formed in the stroke groove, positioning holes are formed in the outer side walls of the two ends of the middle of the shaft body, rotary teeth are integrally connected to the two sides of the bottom of the shaft body, connecting holes are formed in the rotary teeth, and involute tooth profiles are adopted for the rotary teeth. Gear transmission is stable, and vibration is small; the output rotating speed is constant without fluctuation; certain installation errors are allowed to exist in the gear center distance, fluctuation of the output rotating speed cannot be caused, and assembling is convenient. 本发明提供一种手柄杆限位曲轴，其特征在于，包括轴身，轴身采用开设有固定孔的直形结构，轴身顶部设有行程槽，行程槽上设有限位槽，轴身中间两端外侧壁设有定位孔，轴身底部两侧一体连接旋转齿，旋转齿上设有连接孔，旋转齿采用渐开线齿廓。具有齿轮传动平稳，振动小；输出转速恒定无波动；齿轮中心距允许有一定的安装误差，不会导致输出转
