The free ends of the upper joint 1 and the lower joint 2 are locked and fixed through the handle locking structure 3.

Referring to fig. 5 and 6, the locking structure 4 is used to lock the folding handlebar stem and prevent the folding handlebar stem from unfolding when the folding handlebar stem and the scooter pedal are folded. The locking structure 4 includes: a locking bolt 41 and a spring 42. The bottom of the upper joint 1 is provided with a cavity 11, the cavity 11 is arranged close to the rotating shaft sleeve 21, and one surface of the cavity 11 facing the rotating shaft sleeve 21 is open. The locking bolt 41 is movably arranged in the cavity 11, the outer side of the locking bolt 41 is abutted against the rotating shaft sleeve 21, and the inner side of the locking bolt 41 is connected with the cavity wall 11 through the spring 42. The outer side of the rotating shaft sleeve 21 is provided with a groove 211, and when the locking bolt 41 rotates to be parallel to the groove 211, the locking bolt 41 is automatically embedded into the groove 211.

The bottom surface of the locking bolt 41 is provided with a convex handle 411, the convex handle 411 is exposed out of the lower joint 2, and the locking bolt 41 is convenient to be pulled through the effect of the convex handle 411.

In a normal state, the latch 41 compresses the spring 42, and when the latch 41 rotates to be parallel to the groove 211, the latch 41 is pushed into the groove 211 by the elastic restoring force of the spring 42, and enters a latch state, in which the upper joint 1 and the lower joint 2 cannot rotate freely. When the lock is to be unlocked, the convex handle 411 of the lock bolt 41 is pulled backwards, the lock bolt 411 exits the groove 211, and at this time, the lock state is released, and the upper joint 1 and the lower joint 2 can rotate freely.

The handle locking structure 3 includes: a handle 31, a fixed shaft 32, a rotational fastener 33, a torsion spring (not shown), and a safety catch assembly 34. One end of the handle 31 is hinged with the lower joint 2, and the other end is locked with the upper joint 1 through a safety buckle assembly 34. The both ends installation of fixed axle 32 is fixed on lower clutch 2, rotatory fastener 33 cover is established on fixed axle 32, and rotatory fastener 33 can rotate around fixed axle 32, be equipped with between rotatory fastener 33 and the fixed axle 32 the torsional spring.

Referring to fig. 7, the rotating fastener 33 includes: a rotation connection part 331, an upper rotation arm 332, and a lower rotation arm 333. The top end of the upper rotating arm 331 is provided with a barb 334, and the upper joint 1 is provided with a hook groove corresponding to the barb 334. The lower rotating arm 333 is positioned below the handle 31 and contacts with the handle 31, and when the handle 31 rotates downwards, the lower rotating arm 333 is squeezed, so that the lower rotating arm 333 is driven to rotate downwards; when the handle 31 is rotated upward, the lower rotating arm 333 is released, the rotating fastener 33 is reset by the torsion spring, and the barb 334 of the upper rotating arm 331 is caught in the hooking groove.

When the upper connector 1 and the lower connector 2 need to be locked, the handle 31 is turned upwards, the barb 334 of the rotating fastener 33 is clamped into the hook groove, the upper connector 1 and the lower connector 2 are fastened together, and then the handle and the upper connector 1 are locked through the safety buckle assembly 34. When the locking state of the upper connector 1 and the lower connector 2 needs to be released, the safety buckle assembly 34 is firstly unlocked, then the handle 31 is rotated downwards, the handle 31 presses the rotary fastener 33 downwards, the barb 334 of the rotary fastener 33 is separated from the hook groove, and at this time, the upper connector 1 and the lower connector 2 can be freely rotated.

Referring to fig. 8, the safety buckle assembly 34 includes: a push block 341, an elastic member 342, an umbrella screw 343, and a nut 344. The thread end of the umbrella-shaped screw 343 is fixed to the upper joint 1, the nut 344 is mounted on the umbrella-shaped screw 343, and a gap is formed between the nut 344 and the umbrella cap of the umbrella-shaped screw 343. The handle 31 is provided with an installation cavity, and the push block 341 is movably arranged in the installation cavity.
