Description of the Invention: [Technical Field] The present invention relates to a sports equipment, and more particularly to a sports equipment for a user to perform a 'reciprocating motion' of a leg. [Prior Art] Elliptical exercise machine is a kind of sports fitness equipment that has emerged in recent years. Generally speaking, it can guide the left and right pedals to move along an approximately elliptical trajectory, so that the user can simulate walking, running, and stepping. A device that waits for leg movements. Generally, the pedal trajectory of an elliptical exercise machine is mostly fixed. Although the user can usually change the exercise load by adjusting the travel resistance of the pedal (for example, the reluctance system commonly used in the industry), the fixed pedal is meant to mean The movement pattern of the user's legs is also constant, so that it is not only impossible to select the individual's preferred sports form or the muscle part that wants to exercise, but also makes the movement process lack of change and is monotonous and boring. In addition, when the elliptical exercise machine is used, the hands are also respectively gripped on a grip and swinged with the grip, but the grip of the conventional elliptical exercise machine is additionally assembled on the body, such as If the pedal is to be actuated in synchronism with the pedal, it must be swung back and forth by the other connecting rods. This method not only causes the structural design to be complicated, but also increases the hardware installation cost. Moreover, the conventional elliptical exercise machine has a large difference in the height of the pedal movement, which often causes the user to feel the discomfort of the foot joint during the operation of the elliptical exercise machine, thereby causing discomfort in use and an inappropriate exercise posture. It may cause sports injuries, which may cause inconvenience to the user. Most of the above-mentioned ideal conditions can not be presented, and ergonomics needs to be improved. 5 1332409 SUMMARY OF THE INVENTION The main object of the present invention is to provide a sports equipment that can adjust the inclination of a pedal trajectory, thereby selecting leg movements such as walking, running, stepping, and the like, and increasing the movement. Richness and variability. It is still another object of the present invention to provide a sports apparatus that reduces the difference in height above and below the pedal movement and lengthens the distance the pedal moves back and forth, thereby improving the comfort of the exercise and reducing the possibility of sports injuries. It is still another object of the present invention to provide a sports apparatus that allows the grip and the pedal to be directly driven by the linkage mechanism without the need to be driven by other mechanisms, thereby increasing operational convenience and reducing hardware installation costs. In order to achieve the above object, the present invention provides a sports equipment, comprising: a frame body; a guiding device disposed on the frame body; a rewinding mechanism disposed on the frame body, having a first closure a pair of first and second rods, wherein each of the first rod and the second rod respectively includes a first portion and a second portion, wherein each of the first and second rods respectively comprises a first portion and a second portion a rod is pivotally connected to the frame body, and each of the second rods is pivotally connected to the second returning point by a predetermined position between the first portion and the second portion, and the first portion of each of the second rods is corresponding to the first portion The second part of the rod is reciprocatingly displaced, and the second part of each of the second rods is moved along a second returning joint to move in a second closed arch; the two links each include a first And a second portion, the first portion of each of the links is connected to the second portion of each of the second rods, and the second portion of each of the links is guided by the guiding device to perform a movement Actuating; and two pedals, each correspondingly disposed on the second portion of the two links, and each extending a third seal The track enters 6 1332409 (four) (four) 'and the outer ends of the two cranks 122 can be formed separately - the wraparound contact 124' thus provides two rewind contacts that can maintain a relative motion of (10) degrees corresponding to the center point on the circular track & (3) In the present embodiment, the large pulley is coaxially disposed on the crank wheel 121 and located between the two cranks 122 to provide resistance when the rewind mechanism 12 is in operation. Please refer to the picture together! As shown in FIG. 2, the two linkage mechanisms 13 each include an H31 and a second rod 132. Each of the first rods 131 and the second rods 132 includes a first portion 133, 135 and a second portion 134, 136, respectively. Each of the first rods (3) is pivotally connected to the wooden body 1G, and the pivoting position is between the first portion 133 and the second portion 134, and is closer to the first portion 133. In this embodiment, each The second rod (3) is pivotally connected to the second wrap point m adjacent to the first portion 135, and in the embodiment, the first rod i3i has an internal space. (4) The inner accommodating space 137 preferably extends from the second portion m of the first rod to the third "33s, and the size of the inner accommodating space 137 must at least conform to the size of the second rod 132, so that the second rod 132 can be reciprocally displaced in the inner accommodating space 137 of the first rod (3), and the inner accommodating space 137 of the first portion i3i is provided with a guide groove 139 ′ and the first portion 135 of each second rod (1) The first wheel 131 and the second rod 132 can be arranged by the guide groove (9) and the roller 138. The position of the guide groove 139 is corresponding to the roller 138. 138 abuts and then moves correspondingly to the reset, whereby the second rod 132 can be reciprocally displaced within the first inner space 137 by the roller 138, and the first of the first cups 132 The part 136 is subjected to the movement of the second rewinding point Μ 而 — 闭 闭 闭 闭 闭 闭 闭 闭 闭.
