[0040] Preferably, the supporting cavity 201b includes a circular slide 201b-1, which is arranged in the middle of the fixing part 201, and the buckle cavity 201c includes a first buckle 201c-1, a second buckle 201c-2 and a center hole 201c-3, the first buckle 201c-1 and the second buckle 201c-2 have openings opposite to each other, the first buckle 201c-1 and the second buckle 201c-2 are respectively arranged on both sides of the buckle cavity 201c, and the center hole 201c-3 is arranged in the middle of the fixing part 201.

[0041] Preferably, the slide cavity 201d includes a transverse rod 201d-1, a flat groove 201d-2, a rotation groove 201d-3 and an insertion groove 201d-4, the flat groove 201d-2 is arranged at the end of the transverse rod 201d-1, the rotation groove 201d-3 is arranged at the outer arc circle of the slide cavity 201d, and the insertion groove 201d-4 is arranged on the side of the slide cavity 201d, the three grooves are connected, and a positioning groove 201d-41 is arranged at the end of the insertion groove 201d-4.

[0042] In combination with the first two embodiments, the rotating block 201a-1 inside the rotating cavity 201a makes the arc-shaped slider 201a-12 cooperate with the arc-shaped groove 103c-11 through the rotation operation, and the square groove 201a-13 is opposite to the protruding block 103c-12 at this time, so that the arc-shaped slider 201a-12 cannot easily slide out of the arc-shaped groove 103c-11, and the first buckle 201c-1 and the second buckle 201c-2 inside the buckle cavity 201c are respectively opposite to each other. The two states of the rotating part 202, the cooperation of the buckle and the snap ring provides support for the stability of the device, the circular slide 201b-1 inside the supporting cavity 201b provides space for the rotation of the arc-shaped slider 201a-12, the flat groove 201d-2 provides a limit for the folded handle 103, the rotating groove 201d-3 makes the handle 103 smoother when unfolded, and the insertion groove 201d-4 provides placement space and movement space for the unfolded handle 103.

[0043] When in use, first push the handle 103 to disengage the L-shaped clamping head 103a on its side from the clamping block 101c-1. At this time, the sliding head 103c-1 at the end of the handle 103 engages and slides with the lifting groove 202c of the rotating part 202 and slides with the flat groove 201d-2, gradually moving toward the center of the fixed part 201. At this time, the sliding head 103c-1 moves to touch the bottom of the flat groove 201d-2, and the sliding head 103c-1 appears at the bottom of the rotating groove 201d-3. Therefore, the sliding head 103c-1 continues to move and rotate and slide along the rotating groove 201d-3. At this time, the rotating axis 202a is the center of the circle. When the sliding head 103c-1 moves to the top of the rotating groove 201d-3, it continues to move downward along the insertion groove 201d-4. At this time, due to the presence of two fulcrums, namely the rotating axis 202a and the sliding head 103c-1, the handle 103 is supported. Force, when the sliding head 103c-1 moves to the bottom of the insertion groove 201d-4, it contacts the positioning groove 201d-41. At this time, the arc groove 103c-11 of the sliding head 103c-1 is exposed at the end of the arc slider 201a-12, and the arc slider 201a-12 is inserted into the arc groove 103c-11 to lock the handle. When locking, the arc sliders 201a-12 on both sides of the fixed part 201 must be inserted into the arc groove 103c-11, otherwise the fixation will not be firm. On the contrary, when unlocking, the two arc sliders 201a-12 must be deviated from the arc groove 103c-11 to complete the unlocking. When in use, due to the direction of movement of the skateboard, the handle 103 is always pushed toward the direction of the rotating cavity 201a. Therefore, the snap ring 202b at the end of the rotating part 202 is always engaged with the second buckle 201c-2, thereby improving the stability of the device.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
