[0036] 1 is provided with a crank accommodating limit groove 11 on the outer surface. A rocking handle 3 is provided on the outside of the stick body 1 . The rocker accommodating limit groove 11 and the rocker 3 are located on the side of the stick body 1 . The rocker accommodating limit groove 11 is a straight groove.

[0037] see figure 2 , The stick body 1 is a hollow structure. The end of the stick body 1 is provided with a rope threading hole 12 . The side surface of the stick body 1 is provided with a push rod installation hole 13 passing through the rope hole 12 . The push rod mounting hole 13 is pierced with a push rod 14 . A pressing block 15 is connected to the inner end of the push rod 14 . A second spring 16 is arranged between the pressing block and the stick to make the pressing bl...

Embodiment 2

[0052] Embodiment two, see Figure 9 , The difference with the first embodiment is: the rocker 3 includes a first section of the rod body 32 , a second section of the rod body 33 and a third section of the rod body 34 . The third rod body 34 is integrated with the connecting arm 31 . The second rod body 33 is sheathed on the third rod body 34 . The first rod body 32 is sheathed on the second rod body 33 . The first section of the rod body 32 is provided with a holding block 35 . The holding block 35 is located on the side of the rocker 3 away from the stick body 1 .

[0053] When needing to pass through the rocking handle 3 driving wheels, the third section of the rod 34 is extracted from the second section of the rod 33 to change the length of the handle 3 to the required length by making the second section of the rod 33 be extracted from the first section of the rod 32 . Hold on the grip block 35 to shake the handle 3 with your hand.

Embodiment 3

[0054] Embodiment three, see Figure 10 , The difference with the first embodiment is that the rocker 3 is hinged with the driving shaft 41 of the driving wheel 4 through the hinge shaft 7 . The hinge shaft 7 is perpendicular to the plane defined by the rocker accommodating limit groove and the axis of the driving wheel. The rocker 3 is fixed together with the rocker accommodating limit groove 11 through the buckle 9 .

Abstract

The invention relates to a nunchaku. A nunchaku with an adjustable rope comprises a pair of sticks and a connecting rope that enables the sticks to be connected. Each rod is of a hollow structure, and is provided with a rope-passing hole. A driving wheel and a driven wheel are arranged inside each rod, and transmission between the driving wheel and the driven wheel is conducted through a rope winding belt. The ends of the connecting rope pass through the rope-passing holes and then are connected with the rope winding belts. Each driving wheel is movably connected with a rocking handle positioned outside the corresponding stick. The external surface of each stick is provided with a rocking handle accommodation limit groove. The length adjustable nunchaku is provided with the connecting rope that can connect the sticks together, so the problem that a conventional nunchaku has only one function and cannot meet different demands of different users in terms of the length of the connecting rope is solved.
