Under the tensile force of the locking ring 9, the circumferential surface of the expansion ring 5 is deformed and expanded by the notch 13, and the circumferential surface of the collar part 14 is deformed and expanded by the deformation groove 15.

Further, one end of the slide 3 of the embodiment is fixed in the inner cavity of one end of the cue 2 through a connecting piece 19, and one end of the cue 1 is fixed with a sheath 20. The sheath 20 may provide friction, so that the sheath 20 may be used to facilitate the locking or unlocking operation of the cue stick 1 by the user.

Preferably, the end face of the sheath 20 is provided with a first fitting hole 26 for fitting with the large cue 1, one end of the first fitting hole 26 is provided with a second fitting hole 27 for fitting with the small cue 2, and the first fitting hole 26 and the second fitting hole 27 are coaxially arranged. Therefore, the sheath 20 is inserted and installed at the joint of the small rod 2 and the large rod 1, the first adaptive hole 26 is in clearance fit with the circumferential surface of the large rod 1, the second adaptive hole 27 is in clearance fit with the circumferential surface of the small rod 2, and the joint of the large rod 1 and the small rod 2 cannot have a large gap and the large rod 1 and the small rod 2 are also connected tightly by using the coaxial arrangement of the first adaptive hole 26 and the second adaptive hole 27, thereby effectively preventing the joint of the large rod 1 and the small rod 2 from shaking when a user uses the electric golf club.

Further, the expansion ring 5 of the present embodiment is provided with ribs 21 on the circumferential surface thereof and at the projecting ring portion 14. The reinforcing ribs 21 can effectively increase the structural strength of the collar portion 14.

Further, the outer circumferential surface of the small ball bar 2 of the present embodiment is provided with scales (not shown in the drawings). The setting of utilizing the scale makes things convenient for the user directly perceived, the accurate length of adjusting the cue 2 and stretching out.
