Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0024] like Figure 1-3 As shown, in this embodiment, a multifunctional brake handle is provided, including a cylinder 1, which is movably connected to a piston rod 2 and a guide assembly. Specifically, the piston rod 2 is slidingly connected to the cylinder 1 and can clamp the wheel by squeezing oil. The cylinder 1 is rotatably connected to a movable top block 4, and the movable top block 4 is connected to a handle 3 and a pulley 5. The additional pulley 5 can avoid reducing the friction between the handle 3 and the piston rod 2 when pressing the piston rod 2.

[0025] One end of the movable top block 4 is rotatably connected to the pulley 5 and the middle of the handle 3, and the pulley 5 abuts the end of the piston rod 2. Specifically, the pulley 5, one end of the movable top block 4 and the middle of the handle 3 are respectively provided with coaxial hinge holes, and a rotating shaft is inserted into the hinge hole. The pulley 5, the movable top block 4 and the handle 3 are rotatably connected to the rotating shaft.

[0026] The other end of the movable top block 4 is connected to a guide assembly, which controls the swing direction of the movable top block 4 and helps it return to its original position. When braking is required, the user grips the handle 3 to control the rotation of the movable top block 4. After releasing the handle 3, the guide assembly controls the return of the movable top block 4. One end of the handle 3 is threadedly connected to a screw 6, which is inserted into the movable top block 4 to pry the movable top block 4 so that the end of the handle 3, which is hinged to the pulley 5, controls the movement of the piston rod 2.

[0027] Optionally, a fixing block threadably connected to the screw rod 6 is fixedly provided on the handle 3 , the fixing block is embedded and fixed in the handle 3 , and the screw rod 6 passes through the fixing block.

[0028] In this embodiment, an oil chamber is provided within the oil cylinder 1 for storing hydraulic oil. A piston rod 2 is slidably mounted within the oil chamber and extends outward from the cylinder 1. A sealing ring is mounted on the piston rod 2, which abuts the inner wall of the oil chamber, ensuring that the piston rod 2 operates in a sealed environment.

[0029] In this embodiment, a rotating cap 7 and a limiting ring 10 are provided at both ends of the screw rod 6, respectively. The screw rod 6 passes through the movable top block 4 and the handle 3. The limiting ring 10 is interference fit with one end of the screw rod 6 passing through the movable top block 4. The other end of the screw rod 6 passing through the handle 3 is fixed with a rotating cap 7 for controlling the rotation of the screw rod 6. Specifically, the movable top block 4 is provided with a through hole, and the screw rod 6 passes through the movable top block 4 through the through hole. The diameter of the limiting ring 10 is larger than the through hole, and the limiting ring 10 will limit the screw rod 6 to one side of the movable top block 4. That is, when the user controls the handle 3, the deflection of the movable top block 4 will be controlled through the screw rod 6. As shown in the figure, the degree of eversion of the handle 3 can be controlled by adjusting the screw rod 6, thereby controlling the force required for oil pressure and the flow rate of the hydraulic oil in the cylinder 1.

[0030] Specifically, the guide assembly includes a swing block 9 rotatably connected to the oil cylinder 1. The swing block 9 is slidably plugged with a guide rod 8 that passes through the swing block 9. The other end of the movable top block 4 away from the pulley 5 is fixedly connected to the guide rod 8. When the movable top block 4 flips, it pulls the guide rod 8. Since the guide rod 8 is fixedly connected to the movable top block 4, the swing block 9 is rotatably connected to the oil cylinder 1 and can deflect in accordance with the guide rod 8. Optionally, an elastic member such as a spring is sleeved on the guide rod 8 to help the guide rod 8 return to its original position when the user does not hold the handle 3 tightly, thereby pulling the movable top block 4 and the handle 3.

[0031] The technical features of the above-described embodiments can be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. For those skilled in the art, without departing from the concept of the utility model, they can also make several variations and improvements, which fall within the scope of protection of the utility model. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
