     Please refer to  FIG. 1  to  FIG. 3  for a first embodiment of the present invention. The receptacle for tool bit of the first embodiment of the present invention includes a main body  10 , a positioning member  20 , and several pressing members. 
     The main body  10  includes a shell  11 , a base  12 , several insertion grooves  13 , and several apertures  14 . The shell  11  includes an upper cover  111 , a fore cover  112 , a rear cover, and two side covers  114 . The upper cover  111 , the fore cover  112 , the rear cover, and the side covers  114  define a receiving space and an opening therebetween. The opening is located under the shell  11 , and communicates with the receiving space. In the present embodiment, the upper cover  111  is transparent. In other possible embodiments of the present invention, some of the other components may be transparent, or the shell may have no transparent component. The base  12  is received in the receiving space via the opening and arranged in the receiving space detachably and removably. Preferably, one of the shell  11  and the base  12  is disposed with an engagement member, and the other one is disposed with a buckle. The engagement member detachably engages the buckle so as to achieve engagement of the shell  11  and the base  12 . The insertion grooves  13  are provided for tool bits  40  to be inserted therein respectively. The tool bits  40  which are suitable for screwdrivers and shown in the figures are taken for illustration and explanation only. The tool bit  40  is not required to fit with screwdrivers. Each of the insertion grooves  13  includes a first groove portion  131  and a second groove portion  132 . The first groove portions  131  penetrate the upper cover  111  and communicate with the receiving space. Each of the second groove portions  132  penetrates the base  12  and corresponds to one of the first groove portion  131 . The fore cover  112  is disposed with several mark portions  1121 . The mark portions  1121  correspond to the first groove portions  131  respectively. Each of the apertures  14  is formed at a bottom portion of the base  12 , and communicates with one of the second groove portions  132 . Preferably, the second groove portion  132  has an inner diameter larger than a minimal inner diameter of the aperture  14 . The apertures  14  shrink away from the second groove portions  132 , so that the apertures  14  have reversed frusto-conical side walls respectively. 
     The positioning member  20  includes several first curved sections  21 , several second curved sections  22 , and several connecting sections  23 . Each connecting section connects  23  one of the first curved sections  21  to one of the second curved sections  22 , so that the positioning member  20  is formed with a wave-shaped appearance. Preferably, the positioning member  20  is provided with elasticity by bending a metal wire. A top portion of the base  12  is disposed with several restriction portions  121  which correspond to the second groove portions  132  respectively. The restriction portions  121  are formed as concaved arcs. The positioning member  20  is arranged on the top portion of the base  12 . The first curved sections  21  and the second curved sections  22  abut against the restriction portion  121  respectively and protrude elastically in the second groove portions  132  respectively. 
     The pressing members are movably inserted in the apertures  14  respectively. One end of the pressing members  14  are respectively received in the second groove portions  13 , and another end of the pressing members protrude outwardly from the apertures  14 . In the present embodiment, each pressing member includes a pole portion  31  and a button  32 . The pole portion  31  includes a pole  311  and a head portion  312 . The pole  311  pierces movably in one of the apertures  14 . The head portion  312  is disposed to one end of the pole  311 , and is received in the second groove portion  132 . An outer diameter of the head portion  312  is sized between the inner diameter of the second groove portion  132  and the minimal inner diameter of the aperture  14 . Preferably, the head portion  312  of the pole portion has an appearance corresponding to the appearance of the aperture  14 . The buttons  32  are movably disposed to one end of the main body  10 , and protrude out of the apertures  14 . In the present embodiment, each button  32  includes a bottom portion  321  and two side portions  322 . The side portions  322  are disposed to two sides of the bottom portion  321 . The side portions  322  correspond to each other, making the button  32  be formed in U-shaped. The side portions  322  of the button are slidably arranged by two sides of the base  12 . The bottom portion  321  of the button is located under the aperture  14 . The button  32  is completely received in the receiving space of the shell  10  together with the base  12 , so that the button  32  does not protrude outwardly from the opening of the shell  10 . Preferably, the top end of the bottom portion  321  of the button is formed with a positioning hole  3211 . The pole  311  of the pole portion is inserted in the positioning hole  3211 . The bottom end of the bottom portion  321  of the button is formed with a concaved and arc-shaped groove  3212 . The desired appearance of the groove  3212  is provided for fitting with users&#39; forefinger pulp, so that users can press the button  32  comfortably. The pressing member further includes an elastic member  33 . The elastic member  33  is arranged between the top end of the bottom portion  321  of the button and the bottom portion of the base  12 . The elastic member  33  provides elastic force, making the button  32  move generally away from the bottom portion of the base  12 . 
     Please refer to  FIG. 3  and  FIG. 3A . When a tool bit  40  is stored in the receptacle of the first embodiment of the present invention, the pole portion is located at a first position. The tool bit  40  is inserted in one of the insertion grooves  13 . A bottom portion of the tool bit  40  abuts against the head portion  312  of the pole portion. Part of the positioning member  20  elastically engages the notch  41  of the tool bit  40 , so that the tool bit  40  is held in the insertion groove  13 . Please refer to  FIG. 3  and  FIG. 3B . When the user wants to take the tool bit  40  out, the bottom portion  321  of the button is pressed inwardly. Thus, the button  32  pushes the pole  311  of the pole portion to move along the aperture  14  toward the second groove portion  132 . The pole portion is moved to a second position. The head portion  312  of the pole portion pushes the tool bit  40  to move outwardly via the first groove portion  131 . The notch  41  of the tool bit is released from the positioning member  20 , so that the tool bit  40  is no longer restricted by the positioning member  20 . User can draw the tool bit  40  out easily. In addition, since the elastic member  33  is compressed by the bottom portion  321  of the button, the button  32  and the pole portion  31  would be moved back to the first position by the elastic member as soon as the user releases the button. 
     Please refer to  FIG. 4  for a second embodiment of the present invention. The difference between the first and the second embodiments is that the elastic member is removed from the pressing member. Therefore, after the button  32  pushes the pole portion  31  to the second position, the pole portion  31  would be remained at the second position until a tool bit  40  abuts against and presses the pole portion  31  down to the first position. 
     Please refer to  FIG. 5  for a third embodiment of the present invention. The difference between the first and the third embodiments is that the elastic member and the button are removed from the pressing member. Therefore, user can press the pole portion  31  to move to the second position directly for taking the tool bit  40 . When a tool bit  40  is received in the insertion groove, the tool bit  40  can abut against the pole portion  31 , pushing the pole portion  31  to move back to the first position. 
     Therefore, the receptacle can keep and hold the tool bits  40  in the insertion grooves  13  by engagement of the positioning member  20 . In addition, the tool bits  40  can be easily removed from the insertion groove  13  by push of the pressing member and releasement of the positioning member  20 . The tool bits  40  can be drawn out of the receptacle easily. 
     In addition, the tool bits  40  are completely received in the insertion grooves  13  in storing. The tool bits, the users, and the surroundings are protected from unpredictable damage. 
     Besides, the upper cover  111  of the shell may be transparent. Even if the tool bits  40  are completely received in the insertion grooves  13 , user can still recognize what kind of tool bit is received in a particular insertion groove. In addition, the mark portions  1121  disposed on the fore cover  112  can help in recognizing the tool bits  40 , also.
