In the figure: 1. the bicycle comprises a lower joint, 2. an upper joint, 3. a cam, 4. a spindle, 5. a locking handle, 6. a handlebar upper pipe group, 7. a lock catch, 8. a lock catch return spring, 9. a lock catch limit screw, 10. a spindle screw, 11. a cam limit screw, 12. a cam limit elastic sheet, 13. a cam limit elastic sheet locking screw, 14. a lower joint locking screw, 15. a return spring, 16. a return guide pillar, 17. a return spring limit screw, 18. a positioning screw and 19. an adjusting screw;

a. the stress surface of the upper joint (2), the stress surface of the lower joint (1), the locking direction of the locking handle (5), the opening and folding direction of the handlebar upper tube group (6), the closing and combining direction of the handlebar upper tube group (6), the stress point of the spindle (4), the stress point of the upper joint (2) when the stress surface (a) and the stress surface (c) of the lower joint (1) are combined, the stress point of the upper joint (2) when the stress surface (b) and the stress surface (d) of the lower joint (1) are combined, the contact point of the cam (3) and the cam limiting elastic sheet (12) when the locking handle is opened, and the contact point of the cam (3) and the cam limiting elastic sheet (12) when the locking handle is fully opened.

Detailed Description

In fig. 2 and 3, the upper joint (2), the lower joint (1) and the locking handle (5) are combined together by the main shaft (4) and locked by the main shaft screw (10), the cam (3) is fixed on the main shaft (4) by the cam limit screw (11), the lock catch (7) and the lock catch return spring (8) are sleeved in the locking handle (5) and fixed by the lock catch limit screw (9), the handlebar upper pipe group (6), the upper joint (2), the return spring (15) and the return guide post (16) are sleeved together by the return spring limit screw (17) and the positioning screw (18), the cam limit elastic sheet (12) and the cam limit elastic sheet locking screw (13) are fixed in the inner cavity of the lower joint (1), the adjusting screw (19) is fixed at the upper end of the lower joint (1),

when the locking handle (5) is pressed in the direction (h) after assembly, as shown in fig. 1, 3, 4, 5, 6 and 7, the V surfaces (a) and (b) in the upper joint (2) are contacted with the V surfaces (c) and (d) in the lower joint (1), and a guiding effect is generated between the two V surfaces; after the locking handle (5) is pressed in the direction (h), the lock catch (7) can be used for buckling the head of a return spring limiting screw (17) in the handlebar upper pipe group under the elastic action of the lock catch return spring (8) to prevent the locking handle (5) from loosening; meanwhile, the cam (3) can prop against the adjusting screw (19) so as to tighten the upper joint (2) and the lower joint (1), at the moment, the stress surface (a) in the upper joint is completely contacted with the stress surface (c) in the lower joint, the stress surface (b) in the upper joint is completely contacted with the stress surface (d) in the lower joint, when the adjusting screw (19) is adjusted up and down, the stress sizes of the contact points (E), (F) and (G) can be changed, and the stress points (E), (F) and (G) are in a triangular stable structure; after the lock catch (7) is pressed, the lock catch (7) can compress the lock catch return spring (8), the lock catch (7) can be separated from the head of the return spring limiting screw (17), the locking handle (5) can be pulled out according to the direction (i), the locking handle (5) is continuously pulled out after the resistance of the cam (3) at the point (M) on the cam limiting elastic sheet (12) is overcome, and the pressure between the cam (3) and the adjusting screw (19) can be released; under the elastic force action of the return spring (15), the return guide post (16) can jack the upper joint (2), and then the handlebar upper pipe group (6) can move in the direction (j) to realize the folding function; on the contrary, when the upper handlebar tube group (6) moves along the direction (k), the locking handle (5) can not move along the direction (h) together with the upper joint (2) and the upper handlebar tube group (6) to influence the gap between the upper joint (2) and the lower joint (1) because of the resistance of the cam (3) at the point (N) on the cam limiting elastic sheet (12), so that the movement of the upper handlebar tube group (6) along the direction (k) can not be influenced; the lower joint locking screw (14) is used to lock the lower joint (1) to the upper tube of the front fork of a vehicle, which can be sleeved or welded if the joint is used in other parts of a bicycle or scooter.
