The invention discloses a parking brake handle assembly with the variable leverage ratio, and belongs to the technical field of parking brake devices. The handle assembly comprises a tooth plate component, a handle, a wiring harness guide plate and a fixing seat and, is characterized in that a shaft hole is arranged on the tooth plate component; one end of the handle is formed by a pair of connecting plates, and a recess cavity is formed between the connecting plates; the tooth plate component is inserted in the recess cavity; one end of the connecting pin is in pivot joint with the pair of connecting plates of the handle and the tooth plate component, and the wiring harness guide plate and the fixing seat are fixed to the other end of the connecting pin; the distance from the rotating face on the wiring harness guide plate to the connecting pin serves as output arm force, and numerical values of the output arm force on the different radian faces are different; the numerical values of the first output arm force close to the two radial sides of the wiring harness guide plate are larger than the numerical values of the second output arm force close to the bottom, in the height direction, of the wiring harness guide plate, and the values have the tendency of being gradually decreased from the first output arm force to the second output force arm; and assembling is convenient, the yield is high, and the production cost is low; and labor is saved, and the operation comfort is improved.
