Abstract
Description
Technical Field
[0001] The utility model relates to the field of brake handles, in particular to a brake handle with adjustable torque. Background Art
[0002] The existing brake handle usually includes a handle connecting part connected to the pump body and a handle part for holding by hand. The handle connecting part is provided with a handle pressure block, and the piston rod of the pump body is inserted into the handle pressure block. When braking, the hand squeezes the handle part to drive the handle pressure block to press the piston rod. The distance from the connection between the piston rod and the handle pressure block to the handle part squeezed by the hand is the torque required for braking. The existing brake handle has a fixed torque and cannot adapt to users with different torque requirements. Users with less strength need a larger torque, and users with more strength need a smaller torque. Summary of the invention
