After the screw rods 7 with bosses pass through the arc-shaped long limit hole 14, they are extended into or out of the screw hole 15 of the instrument armrest riser 1 through the quick-release cam wrench 3; the front and rear adjustment angle range of the instrument armrest riser 1 is preferably 0-7.5°, and a small handrail and left and right linked handrails are fixedly connected to the instrument armrest riser 1, and the angles of the small handrail and the left and right linked handrails are adjusted along with the instrument armrest riser 1.

[0022] Among them, the front ends of the instrument handrail riser 1 and the main frame fixed tube 2 are respectively fixed with steering column one 16 and steering column two 17, the hexagonal bolt 9 passes through the steering column one 16 and the steering column two 17, and is locked and fixed by the anti-loosening nut 10, the spring washer 11 and the flat washer 12, and the instrument handrail riser 1 rotates around the hexagonal bolt 9; there are two steering column ones at the front end of the instrument handrail riser 1, the two steering column ones are arranged symmetrically on the left and right, and the steering column two is located between the two steering column ones; a U-shaped frame 18 is provided on the top of the main frame fixed tube 2, the bottom of the instrument handrail riser 1 is placed in the U-shaped frame 18, the steering column two is fixed to the front end of the bottom of the U-shaped frame 18, and the arc-shaped long limit holes 14 are penetrated on both sides of the U-shaped frame 18.

[0023] The screw rod 7 with boss passes through the conical stop sleeve 4 and the arc-shaped long limit hole 14 in sequence and is pre-locked in the screw hole 15 of the instrument handrail riser 1. The other side of the screw rod 7 with boss is sleeved with a spring 5 and an enlarged gasket 6, and the quick-release cam wrench 3 is pinned into the end of the screw rod 7 with boss through the cylindrical pin 8; one end of the screw rod 7 with boss is provided with an external thread, and is connected with the screw hole of the instrument handrail riser 1 through the external thread, and the other end of the screw rod 7 with boss is provided with a cylindrical pin hole for the cylindrical pin 8 to pass through, and a boss is provided in the middle of the screw rod 7 with boss; after the quick-release cam wrench 3 rotates outward around the cylindrical pin 8, the conical stop sleeve 4 is separated from the arc-shaped long limit hole 14 of the main frame fixing tube 2 under the action of the elastic force of the spring 5; after the quick-release cam wrench 3 is pulled back inward around the cylindrical pin 8, the conical stop sleeve 4 is pressed into the arc-shaped long limit hole 14 of the main frame fixing tube 2.

[0024] The utility model discloses an elliptical machine with a variable angle of the instrument handrail stand pipe, which can be adjusted forward or backward by 7.5°, so that the fixed small handrail and the left and right linkage handrails can change their positions in the front-to-back direction as the angle of the stand pipe changes, thereby making exercisers of different heights more comfortable during use. When in use, the main frame fixed pipe always remains fixed, and the instrument handrail stand pipe can be adjusted to three angles: a. The instrument handrail stand pipe is parallel to the main frame fixed pipe, in this state, it is generally applicable to people of all heights; b. The instrument handrail stand pipe is tilted forward by 7.5° relative to the main frame fixed pipe, in this state, it is suitable for exercise enthusiasts of 1.4-1.6 meters, as shown in the attached figure. Figure 6 c. The instrument handrail riser is tilted backwards by 7.5° relative to the main frame fixed tube. In this state, it is suitable for exercise enthusiasts with a height of 1.7m-1.9m. Figure 5 shown.

[0025] In the utility model, the instrument handrail riser is connected to the main frame fixing tube by means of hexagonal bolts, and then is locked by means of flat washers, spring washers and anti-loosening nuts, at which time the instrument handrail riser can rotate around the hexagonal bolts; the screw rod with bosses is sequentially passed through the conical retaining sleeve and the arc-shaped long strip hole of the main frame fixing tube, and is pre-locked in the screw hole of the instrument handrail riser, and then the spring and the enlarged washer are inserted into the screw rod with bosses, and then the quick-release cam wrench is pinned into the screw rod with bosses by means of a cylindrical pin.

[0026] When exercisers of different heights use the structure of the utility model to adjust the angle, they only need to rotate the quick-release cam wrench outward. The different wheel diameters of the cam reduce the pressure on the conical stopper sleeve, and the conical stopper sleeve is separated from the arc-shaped long limiting hole of the main frame fixing tube under the action of the spring force. At this time, the user can adjust the instrument handrail standpipe in the front and rear directions according to their own requirements; when the conical stopper sleeve is aligned with the arc-shaped long limiting hole of the main frame fixing tube required by the user, the quick-release cam wrench is pulled back inward, so that the conical stopper sleeve can be tightly pressed into the arc-shaped long limiting hole of the main frame fixing tube.
