The rear spring guide tube 5 has a front end extended into a rear end of the receiving chamber 21 of the piston cylinder 2, and has a rear end secured to a distal end of the barrel 101. The piston spring 4 has a rear end n~ounled on an outer wall of the rear spring guide tube 5. The rear spring guide tube 5 has an inner portion including a front section formed ~.vith a spring receiving chamber 51 and a rear section formed with a guide rod through hole 52.
The nozzle 6 is a hollow cylinder, and has a front section received in a rear section of a transverse hole 104 of the BB bullet supply portion ( 02, a mediate section formed with multiple air collection ports 61, and a rear section formed with an insertion section 62. The transverse hole 104 of tl~e BB bullet supply portion 102 includes a mediate section provided with a bullet feeding chamber 105 having a pressure applying portion 106, and a front section provided with a bullet outlet tube 107.
The sealing tube 7 is formed with a U-shaped receiving space 71, and has a front section extended through a center of the front spring guide tube 3 and secured on the insertion section 62 of the nozzle 6 by multiple positioning bolts 72. The receiving space 71 of the sealing tube 7 has a mediate section formed with a through hole 73. A locking hook 75 is pivoted in the receiving space 71 of the sealing tube 7 by a hook bolt 74, and has an action portion protruded outward from the through hole 73 a~ld formed with a locking opening 752. A T-shaped guide rod 76 is received in a rear section of the receiving space 71 of the sealing tube 7, and has an extension sectiota 7G1 extended outward from a through hole 77 formed in a rear end of the sealing tube 7. The extension section 761 has a rear end received in floe guide rod through hole 52 of the rear spring guide tube 5. The guide rod 76 is secured with the sealing tube 7 by a rod fixing bolt 78. The guide rod 76 has a front section formed with a spring receiving chamber 762 for receiving a hook pllsll spring 763, and a hook push member 764 whose front end face is rested on a rear end face of the locking hook 75.

In operation, referring to Figs. 6-9- with reference to Figs. 1-5, the cocking handle 103 may be pushed toward the rear portion of the barrel 101.
The piston push portion 22 of the piston cylinder 2 is rested on the distal end ol~
the cocking handle 103 so that the piston cylinder 2 may be moved rearward with the cocking handle 103 simultaneously, and the nozzle 6 acid the sealing tube 7 may be moved rearward with the piston cylinder 2 simultaneously as shown Fig. 6. Thus, the front end of the nozzle 6 is detached from the top ol'the BB bullet supply portion 102, so that the BB bullet 108 may be pushed by an upward elastic force to enter the transverse hole 104.
As shown in Fig. 6A, when the sealing tube 71 is moved rearward, the locking hook 75 of the sealing tube 7 is lifted by an inclined face "Z" of the rear spring guide tube 5, whereby the locking opening 752 of the locking hook 75 may be detached from the through hole 73 of the sealing tube 7, so that the sealing tube 7 and the nozzle 6 may be pushed forward by the restoring force of the bullet feeding spring 8, to push the BB bullet 108- in the transverse hole to reach the position of the pressure applying portion 106 of the bullet feeding chamber 105 as shown in Fig. 7.
During the stroke of the piston cylinder 2 pushed by the cocking handle 103, when the locking block 93 rotated counterclockwise enters the locking recess 23 of the piston cylinder 2, movement of the piston cylinder 2 is stopped as shown in Fig. 8, so that the driven portion 932 of the locking block 93 is engaged with the push portion 922 of the block push member 92.
Thus, when the trigger 91 is pressed as shown in Fig. 9, the trigger 9 I
may be pivoted counterclockwise, to pivot and I110Ve the block push member 92 upward, so that the push portion 922 of tlie~block push member 92 may push the driven portion 932 of the locking block 93 upward, so as to pivot the locking block 93 clockwise, thereby detaching the locking block 93 from the locking recess 23 of the piston cylinder 2, so that the piston cylinder 2 may be pressed forward by the restoring force of the piston spring 4, to compress the air contained in the left chamber 1 1 of the cylinder 1, so that tl~e compressed air may be forced through the air- collection ports 61 of the nozzle G toward the bullet feeding chamber 105, so that the BB bullet 108 located at the pressure applying portion 106 may be ejected outward through the bullet outlet tube 107 as shown in Fig. 9.
Referring to Figs. 10 and 1 l, the BB bullet supply portion 102 of the BB bullet feeding device of a toy gun in accordance with a second embodiment of the present invention is mounted on the top of~ the barrel 101, and the cocking handle 103 is mounted on a side of the BB bullet supply portion 102.
Accordingly, the BB bullet feeding device-of a toy gun in accordance with the present invention has the following advantages.
1. The piston cylinder 2 is moved in the cylinder 1 horizontally, and the BB bullet 108 may be rapidly and stably pushed to tile predetermined position by the restoring force of the plStOn Spl'lIlg 4 and the bullet feeding spring 8 during the single rearward stroke of the piston cylinder 2.
2. The BB bullet 108 of the BB bullet feeding device may be fed and triggered in a pneumatic manner easily and exactly, without needing an electric power, thereby saving cost and natural resource, and thereby increasing the lifetime of the BB bullet feeding device.
3. The BB bullet feeding device may be assembled and dismat~lled easily and conveniently, thereby greatly facilitating maintenance of the BB

may be pivoted counterclockwise, to pivot and I110Ve the block push member 92 upward, so that the push portion 922 of tlie~block push member 92 may push the driven portion 932 of the locking block 93 upward, so as to pivot the locking block 93 clockwise, thereby detaching the locking block 93 from the locking recess 23 of the piston cylinder 2, so that the piston cylinder 2 may be pressed forward by the restoring force of the piston spring 4, to compress the air contained in the left chamber 1 1 of the cylinder 1, so that tl~e compressed air may be forced through the air- collection ports 61 of the nozzle G toward the bullet feeding chamber 105, so that the BB bullet 108 located at the pressure applying portion 106 may be ejected outward through the bullet outlet tube 107 as shown in Fig. 9.
Referring to Figs. 10 and 1 l, the BB bullet supply portion 102 of the BB bullet feeding device of a toy gun in accordance with a second embodiment of the present invention is mounted on the top of~ the barrel 101, and the cocking handle 103 is mounted on a side of the BB bullet supply portion 102.
Accordingly, the BB bullet feeding device-of a toy gun in accordance with the present invention has the following advantages.
1. The piston cylinder 2 is moved in the cylinder 1 horizontally, and the BB bullet 108 may be rapidly and stably pushed to tile predetermined position by the restoring force of the plStOn Spl'lIlg 4 and the bullet feeding spring 8 during the single rearward stroke of the piston cylinder 2.
2. The BB bullet 108 of the BB bullet feeding device may be fed and triggered in a pneumatic manner easily and exactly, without needing an electric power, thereby saving cost and natural resource, and thereby increasing the lifetime of the BB bullet feeding device.
3. The BB bullet feeding device may be assembled and dismat~lled easily and conveniently, thereby greatly facilitating maintenance of the BB
2U bullet feeding device.
4. The piston cylinder 2 is received in the cylinder l, and horizontal movement of the piston 2 may feed the BB bullet 108 automatically, thereby facilitating the user employing the BB bullet feeding device.
