[0034] When the brake handle 2 moves toward the direction approaching the handlebar 1, the brake member 4 can be driven to rotate around the second positioning pin 5 to brake. When the brake handle 2 moves away from the handlebar 1, the brake member 4 can be driven to rotate around the second positioning pin 5 to brake. By setting the first positioning pin and the second positioning pin, the brake handle can drive the brake member to rotate around the second positioning pin to achieve the braking function. When the brake handle moves toward the handlebar, the brake member rotates around the second positioning pin to brake; when the brake handle moves away from the handlebar, the brake member also rotates around the second positioning pin to brake. This design is simple and effective, can achieve a two-way braking function, improves the convenience and safety of the operation of the rollator, and provides users with a more stable and reliable braking experience. At the same time, the design of the structure makes the brake handle and the brake line compactly connected, reduces the delay during braking, and enhances the sensitivity of braking. It is simple to assemble, has fewer parts, and saves effort during the braking process, effectively improving the overall performance and user experience of the rollator.

[0035] Preferably, the brake handle 2 includes a handle portion 20 and a connecting portion 21 away from the handle portion 20 and inserted into the insertion port 10. The connecting portion 21 is provided with a sliding hole 210. The first positioning pin 3 is inserted into the sliding hole 210 and fixed to the handlebar 1. When the handle portion 20 moves in a direction away from the handlebar 1, the sliding hole 210 rotates with the connecting portion 21. The positioning pin 3 is placed on the inner wall of the sliding hole 210 and lifts the brake member 4 to rotate around the second positioning pin 5 to brake. The user only needs to move the handle portion 20 to achieve braking. At the same time, through the design of the sliding hole 210 and the positioning pin 3, the brake member 4 can be stably controlled to ensure the accuracy and stability of braking. The overall structure is simple and effective, which improves the braking performance and operating convenience of the walker and provides a safer and more reliable use experience for the user.

The user can choose a suitable braking method according to the needs, which increases the convenience and safety of driving operations. At the same time, through the setting of the sliding hole 210 and the position conversion of the first positioning pin 3, the brake member 4 can be stably controlled, ensuring the accuracy and stability of braking, and providing the user with a more reliable and safe driving experience.

The end of the parking position b is also recessed with a limiting groove 211 facing forward, and the first positioning pin 3 can be engaged with the limiting groove 211 to maintain the parking brake. The first positioning pin 3 can obtain additional limiting support at the parking position b to ensure the stability and reliability of the braking system in the parking state. The setting of the limiting groove 211 can effectively prevent the brake member 4 from accidentally disengaging or moving when parking, thereby improving the safety and reliability of the entire braking system. By cooperating with the limiting groove 211, the first positioning pin 3 can be firmly fixed in the parking position b, effectively maintaining the stable braking of the vehicle in the parking state, and providing users with a safer and more reliable use experience.

When in the braking state, the distance between the connection shaft 24 and the first positioning pin 3 remains unchanged. When the free state is transitioned to the parking state, the brake handle will use the connection shaft as a fulcrum to lift the brake member.

[0042] Preferably, the brake member 4 includes a fixing portion 40 for fixing the brake line 11, a first hinged portion 41 located at an end of the brake member 4 away from the fixing portion 40 and hinged to the second positioning pin 5, and a second hinged portion 42 located in the middle of the brake member 4 and hinged to the connecting shaft 24.
