A level pulling type pet carrying cart includes a main body, a rotatable pushing arrangement and a retaining assembly. The main body has a base frame, a side frame and a plurality of wheels provided below the base frame. The rotatable pushing arrangement includes a connecting arm and a stretchable pushing arm which is capable of rotating with respect to the connecting arm. The retaining assembly includes a retaining base and a connecting band, wherein the connecting band has a first end connected to a top surface of the retaining base and a second end connected to a center on top of the side frame so as to pull the retaining base to move upwardly and also controlling a rotation angle of the stretchable pushing arm. Thus, the whole body is maintained to move smoothly along a horizontal level.

1. A level pulling type pet carrying cart, comprising: a main body comprising a base frame, a side frame, and a plurality of wheels provided below said base frame, wherein said side frame is positioned at a rear side of said base frame;a rotatable pushing arrangement comprising a connecting arm and a telescoping pushing arm, wherein said connecting arm is provided at said rear side of said base frame and also at a rear side of said side frame, wherein said telescoping pushing arm is pivotally connected to a center of said connecting arm, wherein said telescoping pushing arm is pivotally moved with respect to said connecting arm in such a manner that said telescoping pushing arm is adapted to be pivotally moved toward said side frame and adapted to be pivotally move in a direction away from said side frame; anda retaining assembly comprising a retaining base and a connecting band, wherein said retaining base is provided at a center of said telescoping pushing arm and is capable of moving upwardly or downwardly, wherein said connecting band comprises a first end connected to a top surface of said retaining base and a second end connected to a center on top of said side frame so as to pull said retaining base to move upwardly and also controlling a rotation angle of said telescoping pushing arm. 2. The level pulling type pet carrying cart, as recited in claim 1, further comprising two foldable bending rods extended from a front side of said base frame at two sides below said base frame respectively, wherein each of said foldable bending rods is provided with a first wheel at an outer side thereof, wherein two second wheel sets are extended from two sides below said side frame respectively. 3. The level pulling type pet carrying cart, as recited in claim 2, wherein said foldable bending rods are extended from said front side of said base frame at a left side and a right side below said base frame respectively and is capable of rotating in a forward or backward direction. 4. The level pulling type pet carrying cart, as recited in claim 2, wherein said two second wheel sets, each comprising two second wheels, are extended from a front side and a right side below said side frame respectively and is capable of rotating for 360 degrees. 5. The level pulling type pet carrying cart, as recited in claim 1, further comprising a positioning ring provided at a center of said telescoping pushing arm, wherein said positioning ring is wound around an outer circumference of said telescoping pushing arm. 6. The level pulling type pet carrying cart, as recited in claim 5, wherein said retaining base has two sliding slots at one side thereof, wherein said retaining base further comprises two locking members slidably provided in said two sliding slots respectively, so that said retaining base is retained at said positioning ring in such a manner that said retaining base is capable of sliding upwardly or downwardly with respect to said positioning ring. 7. The level pulling type pet carrying cart, as recited in claim 1, wherein when said telescoping pushing arm is moved toward said side frame, said retaining base moves downwardly to be hooked on a top side of said side frame, so as to enable said telescoping pushing arm to be retained on said side frame in position. 8. The level pulling type pet carrying cart, as recited in claim 1, wherein when said telescoping pushing arm is moved toward said side frame, said connecting band rides up to form a ring-shape handle. 9. The level pulling type pet carrying cart, as recited in claim 1, wherein said base frame is a U-shape frame with an opening at a rear side thereof, wherein said side frame is another U-shape frame with another opening at a bottom side thereof. 10. The level pulling type pet carrying cart, as recited in claim 1, further comprising a foldable connecting panel provided between said base frame and said side frame at each side thereof in such a manner that said base frame is capable of being overlappedly aligned with said side frame.
