Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an air compressor featuring a convenient operation, and the air compressor is connected to a connected to a compressor body and an air storage cylinder in a moving wheel rack, and a base and a rotating seat are connected for containing a connecting pipe, and a n-shaped handle rack is pivotally coupled to an edge of the moving wheel rack for bending, so as to achieve the effects of a convenient transportation and moving, an instant installing operations, and a compact size. 
     2. Description of the Related Art 
     At present, the structure of an air compressor generally comprises a main body for compressing air and an air storage cylinder for storing the compressed air, wherein the main body is stacked with the air storage cylinder, and wheels are installed at the external periphery of the bottom of the air storage cylinder. The aforementioned traditional structure has been adopted for decades, and people got used to it already without thinking of a way to improve the structure and provide a more convenient and practical application. Since certain parts such as the connecting pipe of the conventional structure is not connected, it is necessary to carry such parts and install the components by tools. If users need to move the air compressor is moved to another location and forgets to bring the parts and tools with them, the air compressor cannot be installed. Obviously, the prior art requires further improvements. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing shortcomings of the prior art, the inventor or the present invention develops an air compressor featuring a convenient operation to overcome the shortcomings of the prior art. 
     Therefore, it is a primary objective of the present invention to provide an air compressor featuring a convenient operation, and the air compressor comprises a compressor body, an air storage cylinder connected to a moving wheel rack for moving the air storage cylinder by a handle, a connecting pipe with a pipe seat installed in the moving wheel rack, and a n-shaped handle rack pivotally coupled to an edge of the moving wheel rack for bending, wherein the pipe seat comprises a base and a rotating seat for containing the connecting pipe, so that the aforementioned elements are integrated to achieve the effects of a convenient transportation, an instant installing operation and a compact size. 
     Another objective of the present invention is to provide an air compressor featuring a convenient operation, wherein the pipe seat is disposed in the moving wheel rack for combining the base and the rotating seat, such that the connecting pipe is contained in the rotating seat for the movement in a direction of a full arc angle. 
     A further objective of the present invention is to provide an air compressor featuring a convenient operation, wherein the rotating seat of the pipe seat disposed in the moving wheel rack has a U-shaped clamp disposed separately on both sides of the rotating seat for clamping and limiting a distal end of the connecting pipe. 
     Another further objective of the present invention is to provide an air compressor featuring a convenient operation, wherein both sides of the moving wheel rack have a U-shaped pivotal connecting base, and both sides of the pivotal connecting base have an aslant elliptical hole, and a hook frame is on one of the side, so that after a transverse rod is passed through the elliptical hole, both ends of the spring coiling are hooked to the hook frame and the transverse rod respectively, and two pivotal connecting bases are limited by passing the n-shaped handle rack through its opening, such that the transverse rod can block the edge of the handle rack to erect the handle rack on the moving wheel rack for holding. If the transverse rod is pulled downward the handle rack is bent to compress the volume of a space.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1 ,  2 A,  2 B and  6  for the present invention, an air compressor featuring a convenient operation comprises a compressor body  1 , an air storage cylinder  2  connected to a moving wheel rack  3  for moving the storage cylinder  2  by a handle, a pipe seat  31  disposed in the moving wheel rack  3 , a n-shaped handle rack  4  pivotally coupled to the edge, a slide rail  311  disposed separately on both sides of the pipe seat  31 , such that after the base  5  and the rotating seat  6  are combined (as shown in  FIGS. 2A and 2-B ), the base  5  is aligned with the slide rail  311  and pushed into the pipe seat  31  (as shown in  FIGS. 3A ,  3 B and  3 -C), and then the connecting pipe  7  is contained in the rotating seat  6 , and a U-shaped clamp  61  disposed separately on both sides of the rotating seat  6  for clamping and limiting a distal end of the connecting pipe  7  (as shown in  FIG. 2C ), such that after the base  5 , the rotating seat  6  and the connecting pipe  7  are installed at the pipe seat  31  (as shown in  FIGS. 4 and 5A ) to rotate and move the rotating seat  6  in any direction of 360-degree full arc (as shown in  FIG. 5B ) to provide a convenient operation without requiring an adjustment of the moving wheel rack  3 . Further, both ends of the moving wheel rack  3  have a U-shaped pivotal connecting base  32 , and both sides of the pivotal connecting base  32  have an aslant elliptical hole  321 , and a hook frame  322  disposed on a side, such that after a transverse rod  3 A is passed through the elliptical hole  321 , both ends of the spring coiling  3 B are hooked to the hook frame  322  and the transverse rod  3 A respectively. Further, the two pivotal connecting bases  32  are limited by a n-shaped handle rack  4  passing through its opening  323  (as shown in  FIG. 6 ), such that when the transverse rod  3 A blocks an edge of the handle rack  4 , the handle rack  4  is erected at the moving wheel rack  3  for holding (as shown in  FIGS. 1 and 4 ). If the transverse rod  3 A is pulled downwards, the edge of the handle rack  4  is not blocked by the transverse rod  3 A, so that the handle rack  4  can be bent (as shown in  FIGS. 7 and 8 ) to compress the volume of space. The aforementioned components are integrated into the moving wheel rack  3  as a whole to achieve the effects of a convenient transportation and moving, an instant installing operations, and a compact size. 
     In summation of the description above, the present invention improves over the prior art, and complies with the requirements of patent application, and thus is duly filed for patent application.
