Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a pet dropping pickup device, and more particularly to a dropping pickup device that is able to collect pet&#39;s dropping in a convenient way.  
         [0003]     2. Description of Related Art  
         [0004]     Many pet owners especially who like to run their dogs in streets or parks may have a problem of pet dropping. In order to solve the problem of the pet dropping, a conventional pickup device has been provided.  
         [0005]     With reference to  FIG. 14 , a conventional pickup device in accordance with the prior art comprises a first shovel ( 40 ) and a second shovel ( 43 ).  
         [0006]     The first shovel ( 40 ) has a front end, a rear end, a receiving recess ( 41 ) and a handle ( 42 ). The receiving recess ( 41 ) is formed at the front end of the first shovel ( 40 ). The handle ( 42 ) is formed at the rear end of the first shovel ( 40 ).  
         [0007]     The second shovel ( 43 ) is pivotally mounted on the first shovel ( 40 ) and has a front end, a rear end, a pushing recess ( 44 ) and a handle ( 45 ). The pushing recess ( 44 ) is formed at the front end of the second shovel ( 43 ). The handle ( 45 ) is formed at rear end of the second shovel ( 43 ).  
         [0008]     When the pet owner needs to collect pet dropping, the pet owner can hold and open the conventional pickup device. When the conventional pickup device is closed, the receiving recess ( 41 ) of the first shovel ( 40 ) and the pushing recess ( 44 ) of the second shovel ( 43 ) are able to pick up the pet dropping.  
         [0009]     However, the dropping is on the ground so that the pet owners need to lower their body position or on their knees to pick up the pet dropping when the pet owners use the conventional pickup device. If the pet owners are elders or difficult to change their body position, the conventional pickup device is very inconvenient in use.  
         [0010]     To overcome the shortcomings, the present invention provides a pet dropping pickup device to obviate or mitigate the aforementioned problems.  
       SUMMARY OF THE INVENTION  
       [0011]     The primary objective of the present invention is to provide a pet dropping pickup device to allow a pet owner to pick up pet dropping in a convenient way.  
         [0012]     The pet dropping pickup device has a receiving assembly, a shaft assembly and a guiding assembly. The shaft assembly is retractable and mounted on the receiving assembly. The guiding assembly is mounted inside the shaft assembly and controls the movement of the receiving assembly. The shaft assembly is retractable so that the pet owner can pick up the pet dropping without lowering his/her body when the shaft assembly is extended.  
         [0013]     Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
