Handle lever limiting frame

The invention provides a handle lever limiting frame which is characterized by comprising a frame body. The frame body is of an arch structure, a travel groove is formed in the arch top of the frame body, a limiting groove is formed in the travel groove, positioning holes are formed in the outer side walls of the two ends of the arch bottom of the frame body, rotating teeth are integrally connected to the two sides of the bottom of the frame body, and connecting holes are formed in the rotating teeth. The involute profile is adopted for the rotary gear shape. The 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 speedcannot be caused, and assembling is convenient. 本发明提供一种手柄杆限位架，其特征在于，包括架身，架身为拱形结构，架身拱顶部分设有行程槽，行程槽上设有限位槽，架身拱形底部两端外侧壁设有定位孔，架身底部两侧一体连接旋转齿，旋转齿上设有连接孔，旋转齿齿形采用渐开线齿廓。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，不会导致输出转速的波动，便于装配的优点。
