It is a green and environmentally friendly means of transportation. The brake handle generally refers to the brake handle that controls the vehicle. There are currently three popular bicycle braking methods on the market: using a mechanical lever to finally achieve the brake pads rubbing against the bicycle rim or drum brake; using a steel wire cable to finally achieve the brake pads rubbing against the bicycle rim, rubbing the brake disc or drum brake; using a closed oil seal hydraulic pressure to finally achieve the brake pads rubbing against the brake disc.
[0003] The hydraulic oil seal brake handle in the existing technology is mostly fixed to the handlebar by a fixing ring and bolts. After the brake handle is used for a period of time, the bolts on the fixing ring are likely to loosen, resulting in reduced stability of the connection between the brake handle and the front handlebar.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-6The utility model provides a technical solution: a bicycle hydraulic oil seal brake handle, including a brake handle 1, a base 2 is fixedly connected to the brake handle 1, a fixed ring 3 is slidably connected to the base 2, the bottom end of the base 2 is slidably connected to the mounting seat 4 through a support rod, a plurality of first springs 5 are fixedly connected inside the mounting seat 4, a fixing rod 6 is slidably connected at the position corresponding to the first spring 5 inside the mounting seat 4, a pressure-bearing seat 7 is fixedly connected to the top of the mounting seat 4, a mounting groove 8 is opened inside the base 2, a screw rod 9 is rotatably connected inside the mounting groove 8, an extrusion seat 10 is slidably connected inside the mounting groove 8, a symmetrically arranged second spring 11 is fixedly connected inside the extrusion seat 10, a limited seat 12 is slidably connected at the position corresponding to the second spring 11 on the extrusion seat 10, a plurality of limit grooves 13 are opened on the base 2 at positions corresponding to the internal position of the mounting groove 8, and a through groove 14 is opened at the bottom end of the base 2.
[0020] Anti-slip pads are provided at the middle position of the top of the base 2 and the bottom end of the fixing ring 3. The anti-slip pads can enhance the stability of the fixing ring 3 and the base 2. The fixing rods 6 are slidably connected to the inside of the fixing ring 3. The fixing rods 6 are fixedly connected to the first spring 5. The bottom ends of the fixing rods 6 are respectively fixedly connected with the connecting handle 15. The first spring 5 is convenient for driving the fixing rod 6 to reset and move. The top of the pressure-bearing seat 7 passes through the through groove 14 and is located inside the mounting groove 8. The screw rod 9 is threadedly connected to the extrusion seat 10. The screw rod 9 is convenient for driving the extrusion seat 10 to move. The limit seat 12 is fixedly connected to the second spring 11. The limit seat 12 is slidably connected to the inside of the limit groove 13. The second spring 11 is convenient for driving the limit seat 12 to move. The connection between the limit seat 12 and the limit groove 13 is convenient for fixing the position of the extrusion seat 10.
[0021] Specifically, when using the present invention, the base 2 can be fitted to the bottom end of the handlebar, and then the fixing ring 3 can be inserted into the base 2. Then, the two connecting handles 15 can be moved toward the middle at the same time. The connecting handles 15 can drive the two fixing rods 6 to retract into the inside of the mounting seat 4 and squeeze and contract the first spring 5. When the base 2 and the fixing ring 3 are connected, the connecting handle 15 can be released. The first spring 5 can drive the fixing rods 6 to reset. The reset fixing rods 6 can be inserted into the bottom end of the fixing ring 3. At this time, The external tool rotates the screw rod 9, which drives the extrusion seat 10 to move inside the installation groove 8 toward the pressure seat 7. The extrusion seat 10 drives the limit seat 12 to move. The limit seat 12 moves and its outer wall abuts against the wall of the limit groove 13. Since the limit seat 12 moves continuously, the wall of the limit groove 13 will be driven to squeeze the outer wall of the limit seat 12. At the same time, as the extrusion seat 10 moves, the limit seat 12 will be squeezed by the limit groove 13 and completely retracted into the inside of the extrusion seat 10. When the lever 12 is in the locked position, the second spring 11 will push the lever 12 back into position, and the second spring 11 will push the lever 12 into the locked position, so that the lever 12 can be locked.
