BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a stepping foot trainer and, more particularly, to a sewing machine type stepping foot trainer. [0003] 2. Description of the Related Art [0004] A conventional mini stepper comprises a support base, two pedals pivotally mounted on the support base, and a damping mechanism mounted between the support base and each of the two pedals to provide a damping effect to each of the two pedals. Thus, a user's two feet step on the two pedals to move the two pedals upward and downward respectively so as to exercise the user's two feet. However, the exercising effect of the conventional mini stepper is limited. BRIEF SUMMARY OF THE INVENTION [0005] In accordance with the present invention, there is provided a stepping foot trainer, comprising a base frame, a pivot frame pivotally mounted on the base frame, and two spaced pedals mounted on the pivot frame to pivot with the pivot frame simultaneously. [0006] The primary objective of the present invention is to provide a sewing machine type stepping foot trainer. [0007] Another objective of the present invention is to provide a stepping foot trainer, wherein the user's two feet step on the pedals to move the pedals simultaneously and to exert a force to overcome the damping force of the hydraulic damping mechanism so as to exercise the muscle of the user's two feet and legs, thereby achieving the exercising effect. [0008] A further objective of the present invention is to provide a stepping foot trainer, wherein when the pivot frame is pivoted forward and downward, the bumper is movable to abut the front section of the base frame to provide a buffering effect to the pivot frame, and when the pivot frame is pivoted backward and downward, the catch rod is movable to abut the limit pin to prevent an excessive movement of the pivot frame, thereby providing a safety effect to the user when stepping the pedals. [0009] A further objective of the present invention is to provide a stepping foot trainer, wherein the upright handlebar can be held by the user's one hand to provide a balance effect to the user when stepping the pedals. [0010] A further objective of the present invention is to provide a stepping foot trainer, wherein the handlebar is detachably mounted on the base frame, thereby facilitating packaging, storage and transportation of the stepping foot trainer. [0011] Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S) [0012] FIG. 1 is a perspective view of a stepping foot trainer in accordance with the preferred embodiment of the present invention. [0013] FIG. 2 is an exploded perspective view of the stepping foot trainer as shown in FIG. 1. [0014] FIG. 3 is a side plan view of the stepping foot trainer as shown in FIG. 1. [0015] FIG. 4 is a schematic operational view of the stepping foot trainer as shown in FIG. 3. [0016] FIG. 5 is a schematic operational view of the stepping foot trainer as shown in FIG. 4. DETAILED DESCRIPTION OF THE INVENTION [0017] Referring to the drawings and initially to FIGS. 1-3, a stepping foot trainer in accordance with the preferred embodiment of the present invention comprises a base frame 10, a pivot frame 20 pivotally mounted on the base frame 10, two spaced pedals 40 mounted on the pivot frame 20 to pivot with the pivot frame 20 simultaneously, a hydraulic damping mechanism 30 mounted between the base frame 10 and the pivot frame 20 to provide a damping effect to the pivot frame 20, and an upright handlebar 50 mounted on the base frame 10 to facilitate a user holding the handlebar 50. [0018] The base frame 10 has a substantially U-shaped configuration. The base frame 10 has a front section having a side provided with a support tube 16. [0019] The pivot frame 20 has a substantially U-shaped configuration. The pivot frame 20 has a rear section formed with two transverse pivot holes 23. The pivot frame 20 has a plurality of upright bolt holes 21 for mounting the two pedals 40 by a plurality of locking bolts 22. The bolt holes 21 and the pivot holes 23 of the pivot frame 20 are formed in two side bars of the pivot frame 20. [0020] The stepping foot trainer further comprises a transverse support seat 11 mounted on a rear section of the base frame 10, two spaced pivot seats 12 mounted on the support seat 11 for pivoting the pivot frame 20, two pivot bolts 25 each extended through a respective one of the pivot seats 12 and a respective one of the pivot holes 23 of the pivot frame 20 so that the rear section of the pivot frame 20 is pivotally mounted on the pivot seats 12, a transverse limit pin 14 mounted on a first one of the pivot seats 12, an upright catch rod 29 mounted on a bottom of the rear section of the pivot frame 20 and movable to abut the limit pin 14 to prevent an excessive movement of the pivot frame 20, a magnet 122 mounted on a side of the first one of the pivot seats 12, a magnetic detection member 28 mounted on the bottom of the rear section of the pivot frame 20 and movable to pass by the magnet. 122 to count a number of pivot of the pivot frame 20, a first support bracket 15 mounted on the support seat 11, a second support bracket 26 mounted on a front section of the pivot frame 20, and a bumper 27 mounted on a bottom of the front section of the pivot frame 20 and movable to abut the front section of the base frame 10 to provide a buffering effect to the pivot frame 20.
