The leg exercise device further includes two armrests (20), each of the armrests (20) including a sleeve (21) formed on the bottom end (22) of the armrest and sleeved on the pivot shaft (15), and The seat (10) is rotated (see Figure 8) or fixed to the barrel (17) for limited rotation.

Each of the armrests (20) includes an adjusting tube (23) connected to the bottom end (22) of the handrail, and the adjusting tube (23) is selectively aligned with the fixing hole (18), and includes an adjusting groove (24) Longitudinally formed in the interior thereof, wherein it further comprises two adjustment holes (25, 26) formed in the adjustment tube (23) and communicating with the adjustment groove (24), and an adjustment groove (27) also formed in the adjustment tube ( 23) is upper and is located between the two adjustment holes (25, 26) and communicates with the adjustment groove (24) and the two adjustment holes (25, 26).

Each armrest (20) further includes an adjusting bolt (3) having a bolt shaft (30) slidably disposed between the adjusting tube (23) and the adjusting groove (24), and the bolt shaft (30) includes The shaft end (31, 32) can slide out of the adjusting tube (23). For example, please refer to the fourth and fifth figures. The first shaft end (31) of the bolt shaft (30) can be selected to slide out the adjusting tube (23). , and And the fixing hole (18) is disposed on the fixing plate (16), so that the armrest (20) can be fixed to the fixing plate (16) so as not to be rotated relative to the seat (10).

Referring to FIG. 5, the adjusting bolt (3) further includes an adjusting rod (33) which is slidably disposed between the fixing groove (27) or the adjusting hole (25, 26) and includes a handle (34). The handle (34) has a recess (35) inside so that the handle (34) can be slidably sleeved on the adjusting rod (33), and the handle (34) can drive the adjusting rod (33) and the bolt shaft (30) ) slides relative to the adjustment tube (23) and the armrest (20).

Wherein the outer diameter of the handle (34) is larger than the inner diameter of the adjusting hole (25, 26), so that the handle (34) does not pass through the adjusting hole (25, 26), but the handle (34) includes a engaging portion (36) The outer diameter of the handle (34) is relatively smaller than the outer diameter of the handle (34), so that the engaging portion (36) can be selectively inserted into any one of the adjustment holes (25, 26), for example, when the engaging portion (36) When it is worn in one of the adjustment holes (25, 26), it can fix the handle (34) relatively at one of the positions of the adjustment tube (23) without moving relative to the adjustment tube (23).
