Figure 1-Figure 4 As shown, this embodiment is a brake handle, comprising a grip 1, which is used to perform a braking action to provide a driving force, or to perform a release action to release the braking force; an articulated seat tube 2, which is used to be articulated with the middle part of the grip 1, and a locking tooth 211 is arranged around its hinge; a parking card block 3, the middle of which is rotatably connected to the grip 1, and the front end of the parking card block 3 is adapted to be inserted into the locking tooth 211 to lock the state of the grip 1; a reset spring 4, which is arranged between the parking card block 3 and the grip 1; when the grip 1 is pressed, the parking card block 3 switches in the locking tooth 211; when the rear end of the parking card block 3 is pressed, the parking card block 3 and the locking tooth 2 11 separates and resets the handle 1; specifically, the brake handle can be installed on a wheelchair. When the user sits on the wheelchair, the user holds the handle 1 with fingers and applies force to drive the handle 1 to rotate around the hinged seat tube 2 and pull the brake line. At the same time, the rear end of the parking block 3 repeatedly compresses the reset spring 4, and its front end switches and gets stuck in different locking teeth 211, so that the handle 1 maintains the parking state. The user does not need to continuously apply force to hold the handle 1 tightly, which is safer and saves effort. When the parking state needs to be released, while holding the handle 1, press the rear end of the parking block 3 to move its front end out of the locking teeth 211, so that the handle 1 can return to its initial state.
