DETAILED DESCRIPTION

[0020] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] This embodiment provides a handlebar with a bearing and an installation tool, such as Figure 1-5As shown, the turning handle includes a main body 100 and a handle 200. The turning handle can be applied to a motorcycle or a battery vehicle and installed on the handle. The main body 100 is fixed on the handle. The handle 200 can rotate relative to the main body 100. The main body 100 is provided with a Hall element, and the handle 200 is provided with a magnet. The driving speed of the vehicle can be adjusted by rotating the handle 200. The main body 100 is provided with a mounting cavity 110, and the mounting cavity 110 is provided with a bearing 120. The handle 200 has a mounting portion 211 inserted in the mounting cavity 110, and the end of the mounting portion 211 is interference fit with the bearing 120. During installation, the bearing 120 is first fixed on the main body 100, and then the mounting portion 211 is forcibly inserted into the bearing 120 to form an interference fit. Furthermore, the mounting portion 211 has a buckle 212, and the main body 100 has a slot 130 so that the buckle 212 can rotate along the slot 130, thereby preventing the handle 200 from separating from the main body 100. The buckle 212 is engaged with the main body 100 in the mounting cavity 110 of the main body 100, which can reduce the diameter of the handle 200 and improve the comfort of holding.

[0022] The mounting portion 211 is sleeved with a return spring 300 , a first end of the return spring 300 is positioned on the handle 200 , and a second end of the return spring 300 is positioned on the main body 100 . The return spring 300 can automatically rotate the handle 200 back to its original position relative to the main body 100 .

[0023] like Figure 2 , 3 As shown, the handle 200 includes an inner lining 220 and a connecting member 210 fixed on the inner lining 220 , the mounting portion 211 is located on the connecting member 210 , and the connecting member 210 is fixed on the inner lining 220 by screws.

[0024] like Figure 4 , 5As shown, the lining 220 has a retaining ring 221, and the retaining ring 221 has a mounting hole, and the mounting hole is used to insert the installation tool 400. The return spring 300 has a positioning portion 310 positioned on the main body 100, and the positioning portion 310 extends away from the mounting portion 211. The distance from the mounting hole to the rotation axis of the handle 200 is greater than half of the outer diameter of the return spring 300, and is less than the distance from the end of the positioning portion 310 to the rotation axis of the handle 200. The installation tool 400 includes a gripping portion 410 and a limiting column 420, and the limiting column 420 is used to pass through the mounting hole on the turning handle and abut against the positioning portion 310 of the return spring 300, so that the return spring 300 is pre-tightened on the handle 200 before the handle 200 is assembled with the main body 100. The main body 100 has a positioning groove 140, and the positioning portion 310 is embedded in the positioning groove 140. If there is no installation tool 400, and the return spring 300 is not pre-tightened, the second end of the return spring 300 is positioned on the handle 200, and the mounting portion 211 is inserted into the mounting cavity 110. At the same time, the positioning portion 310 is embedded in the positioning groove 140, and the handle 200 is rotated to pre-tighten the return spring 300. Then, the buckle 212 is snapped into the slot 130. During the insertion process, the return spring 300 will be deflected, so that a part of the return spring 300 is attached to the mounting portion 211. The return spring 300 is blocked by the buckle 212 during the insertion process, so that the last part of the structure of the return spring 300 is embedded in the slot 130, and the return function of the return spring 300 will fail. This embodiment uses an installation tool 400, so that before the installation part 211 is inserted into the installation cavity 110, the return spring 300 is pre-tightened into place on the handle 200, and then the installation part 211 is inserted into the installation cavity 110, and the positioning part 310 is embedded in the positioning groove 140. After the installation is in place, the installation tool 400 is pulled out, and the return spring 300 can smoothly perform the return function.

[0025] The liner 220 is provided with a sheath 230, and the sheath 230 covers the installation hole. After the installation tool 400 is pulled out, the sheath 230 is put on to prevent foreign matter from entering the installation hole.

[0026] like Figure 4 As shown, the limiting column 420 has a limiting groove 421. The positioning portion 310 is embedded in the limiting groove 421 to prevent the return spring 300 from deflecting during the pre-tightening and insertion process, thereby improving the installation efficiency. The outer dimension of the grip portion 410 is larger than the mounting hole on the turning handle to prevent the grip portion 410 from passing through the mounting hole.
