It is convenient for the user to loosen the connecting member 4 according to their own needs to adjust the angle of the finger-operated shifter 2, which is convenient for after-sales maintenance and replacement. At the same time, under the meshing action of the ratchet teeth 11 of the grip fixing member 1 and the tooth grooves 31 of the finger-operated shifter 2, the finger-operated shifter 2 and the grip 100 are relatively fixed. This finger-operated grip assembly can be directly installed on the grip 100. The grip fixing member 1 and the finger-operated shifter 2 are precisely and tightly matched through the ratchet teeth 11 and the tooth grooves 31, with high safety. Moreover, the structure of the finger-operated grip assembly is simple, has good aesthetics, low cost, few installation procedures, and low precision requirements for accessories.

[0042] Further, referring to Figures 4-6The finger shifter 2 further includes a locking member 24. The finger shifter 21 is provided with a connecting hole 211. The locking member 24 is disposed in the connecting hole 211, and the outer periphery of the locking member 24 is clamped to the hole wall of the connecting hole 211. The locking member 24 is provided with a connecting hole 241. The connecting member 4 passes through the through hole 231 and is connected to the connecting hole 241 of the locking member 24. Specifically, the outer periphery of the connecting member 4 is provided with an external thread, and the hole wall of the connecting hole 241 is provided with an internal thread. The connecting member 4 and the locking member 24 are meshed and connected by the internal thread and the external thread. The outer periphery of the locking member 24 is provided with a clamping portion 242, and the locking member 24 is clamped and fixed in the connecting hole 211 through the clamping portion 242. First, the locking member 24 is snap-fitted and fixed in the connecting hole 211 of the finger shifter 21. Then, the connecting member 4 passes through the through hole 231 of the second mounting portion 23 and is threadedly connected to the connecting hole 241 of the locking member 24. The locking member 24 plays a role of fixing and locking, so that the finger shifter 2 is buckled to form the mounting hole 3 and is fixedly mounted on the turning handle 100 for a firm connection.

[0043] Further, refer to Figure 4 , there are multiple locking members 24, the number of connecting members 4 is the same as that of locking members 24, and multiple through holes 231 are correspondingly provided, and multiple connecting members 4 respectively pass through the multiple through holes 231 and are connected to the corresponding locking members 24. Specifically, in this embodiment, there are two connecting members 4, corresponding to the number of through holes 231 of the second mounting portion 23, the number of locking members 24, and the number of connecting holes 211 of the finger shifter 21 are all two, and the two connecting members 4 respectively pass through the corresponding through holes 231 and are fixed in the connecting holes 211 of the finger shifter 21 under the action of the locking members 24, further strengthening the stability of the connection and ensuring that the finger shifter 2 is not easily loosened relative to the turning handle 100 during repeated use.

[0044] Further, refer to Figures 3-5 The finger shifter 2 further includes a fixed shaft 5, and the first mounting portion 22 and the second mounting portion 23 are rotatably connected via the fixed shaft 5. Specifically, the first mounting portion 22 and the second mounting portion 23 are respectively provided with shaft holes, and the fixed shaft 5 passes through the shaft holes of the first mounting portion 22 and the shaft holes of the second mounting portion 23, so that the first mounting portion 22 and the second mounting portion 23 can be relatively rotatably matched under the action of the fixed shaft 5.

[0045] Further, refer to Figure 2 The finger shifter 2 further includes a protrusion 25. The finger shifter 21 has a pressing end surface, and the protrusion 25 is arranged on the pressing end surface. Specifically, the protrusion 25 is convexly arranged on the pressing end surface of the finger shifter 21, which increases the friction force on the user's finger to prevent the finger from slipping and failing to shift the finger shifter 2.

[0046] Further, refer to Figure 4, the shift lever 21 and the first mounting portion 22 are integrally formed. Specifically, the shift lever 21 and the first mounting portion 22 are integrally formed by casting or the like, with high structural strength, ensuring that the shift lever 21 is not easily broken during repeated use, extending the service life and reducing the replacement cost.

[0047] Furthermore, referring to Figures 1-2 , the twist grip fixing member 1 and the shift lever 2 are both made of aluminum alloy material. Specifically, the aluminum alloy material has relatively high strength, the specific strength is close to that of high alloy steel, the specific stiffness exceeds that of steel, and it has good casting performance and weldability, and can be used as a structural material, ensuring that the overall structural strength of the twist grip shift lever assembly is high and not easily damaged. Optionally, the twist grip fixing member 1 and the shift lever 2 are both made of plastic material, with low replacement cost.

[0048] This embodiment also provides an electric scooter, including a twist grip 100 and the above-mentioned twist grip shift lever assembly, and the twist grip shift lever assembly is arranged on the twist grip 100. Specifically, the twist grip fixing member 1 and the shift lever 2 are precisely and tightly matched through the ratchet teeth 11 and the tooth grooves 31, with high safety. Moreover, the twist grip shift lever assembly has a simple structure, few installation procedures, and low precision requirements for accessories, thereby reducing the cost of the electric scooter. At the same time, the connecting member 4 passes through the through hole 231 of the second mounting portion 23 and is fixedly connected to the shift lever 21, making the shift lever 2 fixed relative to the twist grip fixing member 1, facilitating the user to adjust the angle of the shift lever 2 as needed and facilitating after-sales maintenance and replacement.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
