And preferably, the leg 22 can be rotated on the arm 21, and after rotating to a proper angle, it is fixed by a knob. The different positions of the leg rest 22 in the plane of rotation are intended to match the different training positions of the exerciser.

The main body 10 includes a driving block 11 and a spring 12 controlled by the driving block 11, and the spring 12 is expandable and compressible under the control of the driving block 11. Specifically, the upper end of the spring 12 is placed on the lower wall of the driving block 11, and when the driving block 11 is raised, the spring 12 is in a compressed state, and when the driving block 11 is lowered, the spring 12 is returned to the original position.

Further, for the driving of the leg rest member 20 and the main body 10, both sides of the driving block 11 are respectively provided with the first tooth structures 31; and the inner end of the arm 21 is provided with a second tooth formation 32 which engages the first tooth formation 31, the two leg rest members 20 being initially separated and the spring 12 being in the extended condition.

When the spring 12 is used, the two leg rest parts 20 are clamped, and the rotating support arm 21 drives the driving block 11 to move upwards through the tooth structure so as to compress the spring 12.

The utility model has the advantages that, in the initial state, the two leg rest parts 20 are opened, and the spring 12 is in an extension state; the two leg rest parts 20 are clamped by applying an opposite force, the rotating support arm 21 drives the driving block 11 to move through the tooth structure so as to compress the spring 12, and an exerciser overcomes the tension of the compression spring 12 through leg clamping action, so that the exercise effect is obtained. This nojirimus device 100 structure is simple relatively, and stability is high.

Preferably, the first tooth structure 31 is a straight tooth and the second tooth structure 32 is an arc tooth. The arc-shaped teeth are designed to match the rotation track of the arm 21, and the straight teeth match the moving direction of the driving block 11. Further conversion of the force of the opposing pinches into a force of the linear direction compression spring 12 is achieved.

More specifically, the main body 10 of the present embodiment further includes a base 13 and a driving rod 15, wherein the arm 21 is coupled to the base 13, and the arm 21 can rotate relative to the base 13. The base 13 is provided with a guide hole 14 through which the driving block 11 is linearly moved.

Preferably, the driving rod 15 is a screw, and the limiting portion 16 includes a knob c screwed to the bottom of the screw, and the amount of compression of the spring 12 can be adjusted by rotating the knob c. When the exerciser needs to adjust the exercise intensity, the compression amount of the spring 12 can be adjusted by turning the knob c, thereby changing the elastic force which the exerciser needs to overcome when the exerciser pinches the leg part 22.

Further, the outer surface of the knob c is arranged with a thread structure to increase friction when a user rotates.

As shown in fig. 7 and 8, in the coupling structure between the arm 21 and the base 13, the arm 21 is provided with a sector-shaped coupling portion a, the arc-shaped teeth are provided on the sector-shaped coupling portion a, and two sides of the base 13 are respectively provided with a coupling cavity b for accommodating the sector-shaped coupling portion a and rotating the sector-shaped coupling portion a.
