Example two

Referring to fig. 7 and 8, in some embodiments, the diameter of the through hole 3311 may be smaller than the diameter of the ball 333.

Of course, it is understood that in other embodiments, the grooves 3111 may not be evenly spaced, and are not limited herein.

Further, in some embodiments, the groove 3111 may preferably be a spherical groove, and an inner surface of the groove 3111 is matched with a surface of the sphere 333, that is, the inner surface of the groove 3111 is a spherical surface matched with the surface of the sphere 333.

Thus, the matching surface between the ball 333 and the groove 3111 is a spherical surface, when the first rotator 31 and the second rotator 32 rotate relatively, the resistance of the ball 333 sliding into and out of the groove 3111 is small, and the ball can slide more smoothly when the angle adjustment of the step rotation is performed, so that the user does not need to use a large external force to rotate the lamp body 20, and the abrasion of the ball 333 can be reduced to prolong the service life.

It is understood that in other embodiments, the groove 3111 can have other shapes, for example, the groove 3111 can be a V-shaped groove, and for example, the groove 3111 can be a trumpet shape, and the ball 333 can be easily snapped into the groove 3111 and easily separated from the groove 3111 without limitation.

EXAMPLE III

Thus, the number of the locking assemblies 33 is set to be at least 2, so that a large abutting force can be simultaneously applied to the first rotating shaft part 311, the situation that the first rotating body 31 and the second rotating body 32 can rotate relatively only under a slight acting force due to a small locking force of a single locking assembly 33 is avoided, and the stability in locking is improved.

Further, referring to fig. 3, the number of the locking assemblies 33 is two, and the distance between the two locking assemblies 33 is greater than or equal to half of the axial length of the first rotating shaft portion 311.
