Title: Saddle stapler

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a stapler, and more particularly to a saddle stapler that is assembled and dissembled quickly. 
     2. Description of the Prior Art 
     Referring to  FIG. 1 , a conventional stapler includes a base  1 , a ruler  2 , and a filling mechanism  3 , wherein the base  1  is bent at a predetermined angle to define a bottom abutting section  4  formed on a bottom end thereof, a top arm section  5  above the bottom abutting section  4 , and the bottom abutting section  4  is used to put the stapler on a plane, the ruler  2  is connected on a free end of the bottom abutting section  4 , and the filling mechanism  3  is disposed on a free end of the top arm section  5 , the ruler  2  includes a disassembling trench  7  arranged thereon in response to an outlet  6  of the filling mechanism  3 , such that a receiving space is formed between the bottom abutting section  4  and the top arm section  5  to insert a paper, and the ruler  2  also includes a scale  8  to align the paper with the scale  8  so as to fix a staple at a central position of the paper, thus folding the paper into two parts evenly to make a book. 
     However, the ruler  2  of such a conventional stapler is fixed on the bottom abutting section  4  of the base  1 , therefore when desiring to fixing the staple on a peripheral side of the paper, the ruler  2  is not used but interface the stapling process. Likewise, the ruler  2  can not be disassembled from the stapler to occupy store space and is not portable easily due to its large size. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention is to provide a saddle stapler of which the ruler is assembled with and disassembled from the quick removing assembly quickly to lower store space and size and to be portable easily. 
     To obtain the above objective, a saddle stapler contains: 
     a base including a bottom abutting section formed on a bottom end thereof, a top arm section bently extending from one end of the bottom abutting section, a support section obliquely extending upward from another end of the bottom abutting section; 
     a filling mechanism fixed on an edge of the top arm section of the base to receive at least one type of and one staple, and the staple being forced by pressing the filling mechanism so that it is pushed outward from an outlet of the filling mechanism; 
     a quick removing disassembly mounted on the support section of the base, and including a horizontal slot and at least one positioning projection; 
     a ruler including a scale defined thereon, the scale includes a number of standard scale codes of papers, and the ruler also including at least one orifice, the ruler being inserted into the horizontal slot of the quick removing assembly so that the positioning projections retain in the orifices of the ruler, and the ruler being removed from the horizontal slot of the quick removing assembly so that a positioning projections disengage from the orifices of the ruler.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention. 
     Referring to  FIGS. 2-7 , a saddle stapler  100  in accordance with a preferred embodiment of the present invention comprises a base  10 , a filling mechanism  20 , a quick removing assembly  30 , and a ruler  40 . 
     As shown in  FIGS. 2-4 , the base  10  is integrally made of a rigid and flexible plate, and includes a bottom abutting section  11  formed on a bottom end thereof, a top arm section  12  bently extending from one end of the bottom abutting section  11 , a support section  13  obliquely extending upward from another end of the bottom abutting section  11 , wherein the bottom abutting section  11  and the top arm section  12  are parallel to each other and spaced away from a certain distance, and the bottom abutting section  11  is use to put the base  10  on a plane securely. 
     The filling mechanism  20  is fixed on an edge of the top arm section  12  of the base  10  to receive at least one type of and one staple, the staple is forced by pressing the filling mechanism  20  (not shown) so that it is pushed outward from an outlet  21  of the filling mechanism  20 . Since the filing mechanism  20  is well-known prior art, further remark is omitted. 
     The quick removing disassembly  30  is mounted on the support section  13  of the base  10  to provide a remove groove to bend the staple and to position or remove the ruler  40  in a quick sliding manner. 
     The quick removing assembly  30  includes a connecting member  31 , two screwing elements  32 , a resilient piece  33 , and a locking unit  34 . The connecting member  31  includes a panel  311  and two filling blocks  312 , and the panel  311  is bent at a predetermined angle to define a first coupling section  313 , a disassembling section  314 , and a second coupling section  315 , the disassembling section  314  is connected between the first coupling section  313  and the second coupling section  315  at a predetermined included angle, and the fitting blocks  312  are connected on an inner surface of the first coupling section  313  and spaced apart from each other at a predetermined distance, each fitting block  312  includes a horizontal slot  316 , the first coupling section  313  is disposed on the support section  13  of the base  10  by using the screwing elements  32 , and the disassembling section  314  includes a recess  317  to remove the staple formed on an outer surface thereof in response to the outlet  21  of the filling mechanism  20 , the second coupling section  315  includes a hole  318  arranged thereon, and the resilient piece  33  includes a fixing bore  331  and at least one positioning projection  332 , the locking unit  34  includes a bolt  341  and a nut  342 , the bolt  341  is inserted into the fixing bore  331  of the resilient piece  33  through the hole  318  of the connecting member  31  to screw with the nut  341 , thus positioning the resilient piece  33 . 
     The ruler  40  includes a scale  41  defined thereon, the scale  41  includes a number of standard scale codes of papers, such as A4, A5 ect., and the ruler  40  also includes at least one orifice  42 . 
     In operation, the ruler  40  is inserted into the horizontal slot  316  of the quick removing assembly  30  so that the positioning projections  332  of the resilient piece  33  retain in the orifices  42  of the ruler  40  as shown in  FIG. 4 , thus connecting the ruler  40  and the quick removing assembly  30  together to fix the staple at a central position of a paper  99  as illustrated in  FIG. 5 . 
     Moreover, when desiring to fix the staple at a peripheral side of another paper  98 , the ruler  40  is removed from the horizontal slot  316  of the quick removing assembly  30  as shown in  FIG. 6  so that the positioning projections  332  of the resilient piece  33  disengage from the orifices  42  of the ruler  40 , thus disassembling the ruler  40  quickly to fix the staple at the peripheral side of the paper  98  as illustrated in  FIG. 7 . 
     Also, the staple is capable of being fixed onto the peripheral side of the paper when the ruler  40  is connected with the quick removing assembly  30  without interfacing the filling process of the staples. 
     Thereby, the ruler  40  is assembled with and disassembled from the quick removing assembly  30  quickly to lower store space and size and to be portable easily. 
     While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
