In one embodiment, the left handle 3 further comprises: a first stop collar 32 and a first stop screw 33; the right handle 4 further includes: a second stop collar 42 and a second stop screw 43; wherein,
the side wall of the first joint 31 is provided with a pair of first openings 311 passing through the opposite sides from one side, and the side wall of the second joint 41 is provided with a pair of second openings 411 passing through the opposite sides from one side; the first clamping position is a pair of first limiting notches 211 on the side wall of the first connecting port 21, the second clamping position is a pair of second limiting notches 212 on the side wall of the first connecting port 21, the third clamping position is a pair of third limiting notches 221 on the side wall of the second connecting port 22, and the fourth clamping position is a pair of fourth limiting notches 222 on the side wall of the second connecting port 22;

In the present embodiment, the left handle 3 is described as an example: the first opening 311 is a pair of openings with the axis of the first joint 31 as a symmetry axis, the first limit screw 33 can slide left and right in the first opening 311, which corresponds to the sliding groove of the first limit screw 33 formed in the first opening 311, and the first limit screw 33 can be moved left and right in the first opening 311 by an external force, for example, by pulling the first limit screw 33 by a user's hand, so that the first limit screw 33 can slide left and right in the first opening 311. When the left handle 3 needs to be fixed at the position of the use state, only the first connector 31 of the left handle 3 needs to be inserted into the first connecting port 21 at the position of the use state, at this time, one side of the first opening 311, which is close to the first limiting notch 211, is aligned with the first limiting notch 211, and then the first limiting screw 33 is pulled onto the first limiting notch 211 to be clamped, so that the left handle 3 is fixed. It should be noted that the first limiting screw 33 may be connected to the first limiting notch 211 through an interference fit, and may be further connected in an auxiliary manner through a spring as described in the following embodiments. When the left handle 3 is detached, the first limit screw 33 is pulled out from the first limit notch 211, and the left handle can be rotated and stored. The left handle 3 is fixed at the folded state position, which is similar to the principle and is not repeated; similarly, the principle of fixing and detaching the right handle 4 in the use state position and the folded state position is similar to that of the left handle 3, and will not be described again. In addition, the first limiting notch 211 and the second limiting notch 212 may be disposed adjacently, that is, the second limiting notch 212 is located beside the first limiting notch 211, specifically as shown in fig. 9, in this case, the position of the left handle 3 in use is slightly inclined to the front of the vehicle head, the user extends forward to operate the handle bar, the whole vehicle can be made smaller, and the inclination effect can be as shown in fig. 2.

The first connector 31 is a tubular connector, and the interior of the first connector can accommodate a brake cable to pass through. The first limiting hook 312 is disposed inside the first joint 31 and near the opening of the first joint 31, and the first opening 311 is disposed at a position of the first joint 31 that is more inward than the first limiting hook 312, so that when one end of the first spring 34 is connected to the first limiting hook 312 and the other end is connected to the first limiting screw 33, the first spring 34 is in a stretched state, and can always generate an elastic force to pull the first limiting screw 33 toward the first limiting hook 312. Because the first connector 31 is inserted into the first connecting port 21 for connection, when in connection, the first limiting hook 312 is located inside the first limiting notch 211, that is, a pulling force is always generated to clamp the first limiting screw 33 on the first limiting notch 211, so as to prevent the first limiting screw 33 from being separated from the first limiting notch 211. The first limiting screw 33 is connected to the second limiting notch 212 in a similar manner to that described above, and will not be described again.

Or 170 degrees, etc., after bending, the longer section is the first main rod 35, the shorter section is the first connecting rod 36, and specifically, a 155 degree bend is made at 1/4 of the straight pipe.
