The invention relates to a handle lock and a manufacturing process thereof. By the adoption of the handle lock and the manufacturing process thereof, the technical problems that existing similar products cannot be easily used in combination with connecting rods, production is inconvenient, and the cost is high are solved. The handle lock is characterized in that one end of a handle of the handle lock is connected with a fixed base support of a fixed base through a first rivet, one end of a second transmission plate in the fixed base support is fixed through the first rivet, and a lock cylinderat the other end of the handle is connected with a steel bolt through a pedestal; a pedestal fixing plate for mounting the pedestal is integrally connected with the handle, and the steel bolt is locked at the tilted tail end of the fixed base; openings in opposite positions of a first transmission plate and the second transmission plate arranged in the fixed base support in a mirror symmetry modeare connected to the handle through second rivets and located at a V-shaped notch of the fixed base support; and one end of the first transmission plate is connected with the fixed base support through a pin, and the other ends, capable of being opened in a V shape, of the first transmission plate and the second transmission plate are connected with one end of a connecting rod. The main components are all formed by cold-rolled plates through punching and are fixed through welding.
