Summary:The utility model discloses a propeller handle variable-pitch pin structure for a variable-pitch propeller, which comprises a propeller aluminum sleeve handle provided with a central channel. A variable pitch pin is arranged at the shaft end of the propeller aluminum sleeve handle; the axis of the variable pitch pin does not coincide with the axis of the propeller aluminum sleeve handle. A mounting hole for mounting a variable pitch pin is formed in the shaft end of the propeller aluminum sleeve handle, and the mounting hole and the propeller aluminum sleeve handle are integrally formed. And the variable pitch pin is mounted in the mounting hole in a threaded connection manner. According to the utility model, the propeller handle with the variable-pitch shifting pin hole can be directly produced in the production and manufacturing process of the propeller made of the composite material. And the position of the variable-pitch shifting pin and the paddle handle are integrally formed, so that the position precis
