❹ 肋2帶動該凸輪件4〇2產生逆時針方向的旋轉’然而，由於 戎保險件401的移動將受限於該預定距離D (見圖^，因 此，該凸輪件402會限制該塞件8〇2的下移量，使該塞件 802上的密封環8〇3移動至介於該等第一、二開口 9〇4、 905之間，如此，從該控制氣室5〇1内流動至該上腔室 内的高壓氣體602即會經該等第一開口 9〇4、該連通空間 9〇6、該等第二開口 9〇5、該下腔室9〇3與該排氣出口 9们 排放至外界，造成該控制氣室5〇1内產生壓降，而致動該 頂内座5朝上移動至開放該活塞室1〇2，使該貯氣室^的内 的高壓氣體602可進人該活塞室1G2,而致動該擊釘件2將 該出釘部ιοί内的釘子301擊出，進而將一金屬連接器6〇4 釘固於該工件603上。 相反地，如圖5、6所示，當該保險件4〇1的第一端部 4〇3不定位於距該工件6〇3該預定距離d (見圖丨）内且 該閥桿702被該扳機6〇1觸壓時，該闕桿7〇2上的密封環 7〇3會上移至密封該腔冑7〇9，㈣斷該貯氣冑ι〇3内的高 壓氣體602經該第一過道7〇6繼續流入該腔室7〇9内該 密封環704會上移至不再密封該腔室彻，使該第二、三過 道707、708互相連通’如此， 體602即會經該控制氣道1 〇4 該控制氣室501内的高壓氣 、該二、三過道707、708、 該通道9〇1 ’而流動至該上腔室9〇2内，進而朝下推動該塞 件802帶動該凸輪件產生逆時針方向的旋轉，然而， 由於該保險件401的移動將不受限於該預定距離D (見圖1 )，因此，該凸輪件4〇2不會限制該塞件8〇2的下移量，使 7 200948554 該塞件802上的密封環8〇3移動至等第二開口 9〇5下方， 而阻斷該等第二開口 905與該下腔室9〇3連通，如此，該 控制氣室501内的高壓氣體6〇2即無法經該排氣出口 排放至外界，造成該控制氣室5〇1内無法產生足夠的壓降 去致動該頂内座5 ’因此’該擊釘件2即無法將該出釘部 101内的釘子301擊出。 ❹ ❹ 簡言之’該控制氣室501内的高壓氣體6〇2需先通過 該觸發閥7’再流動至該接觸閥8推動該塞件觀帶動該保 險機構4，才能決定是否致動該擊釘件2。 【發明内容】 因此，本發明之目的，即在提供一種由貯氣室的高壓 氣體來帶動保險機構以決定是否擊發的氣動保險式打釘搶 本發明氣動保險式打釘搶，包含一本體、一擊釘件、 -啟動開關、—扳機裝置，及—保險裝置。該本體具有一 沿-軸向延伸的出釘部，及一貯存一高麼氣體的貯氣室。 該擊釘件是沿該軸向可移動地裝設於該本體内。該啟動開 關是設置於該本體，並具有一觸壓部，該觸壓部可在一未 啟動位置與-啟動位置之間移動，當該觸壓部在該啟動位 置時，該啟動開關可致動該擊料。該扳機裝置是栖設於 該^體亚鄰近於該啟動開關，該扳機裝置可相對於該本體 擊發位置及-擊發位置之間拖轉。該保險裝置具有 ’°該軸向可移動地裝設於該本體的保險機構，及一沿該 軸向可移動地裝設於該本體且可操作地與該扳機裝置連接 8 200948554 的閥件’該保險機構具有一沿該軸向設置的氣室，該閥件 具有一延伸至該氣室内的氣道’當該扳機裝置在該未擊發 位置時’該觸壓部是在該未啟動位置’該氣道是與該貯氣 至不連通’當該扳機裝置移動至該擊發位置時，該扳機裝 置驅使該閥件沿該軸向移動至該氣道連通於該貯氣室，該 貯氣室内的高壓氣體經該氣道流入該氣室，驅使該保險機 構沿該軸向移動，若該保險機構相對於該出釘部移動不超 過一保險距離，該扳機裝置迫使該觸壓部移動至該啟動位 置’若該保險機構相對於該出釘部移動超過該保險距離， 該觸壓部保持在該未啟動位置。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 以下配合參考圖式之一較佳實施例的詳細說明中，將可清 楚的明白。 參閱圖7、8、9,為本發明氣動保險式打釘搶的一較佳 實施例，該打釘搶包含：一本體10、一擊釘件2〇、一釘匣 3〇、一頂内座40、一啟動開關50、一扳機裝置6〇，及—保 險裝置70。 該本體10具有一沿一軸向X延伸的出釘部11、一活塞 室12 ' —貯存一高壓氣體100的貯氣室13，及一實質上沿 該軸向X設置並與該貯氣室13連接的槽道14。 該擊釘件20是沿該軸向χ可移動地裝設於該本體1〇 的活塞室12内’並延伸至該出釘部n内。 該釘匣30是連接於該出釘部u與該本體1〇之間，並 9 200948554 裝填有多數的釘子31。 該頂内座40是設置於該本體1〇内，該頂内座4〇與該 本體10之間可界定出-與該啟動開關5G連接的控制氣室 41 〇 該啟動開關5G是設置'於該本體1Q，並具有—沿該轴向 X朝外延伸出的觸壓部5卜該觸壓部51可在一未啟動位置 (見圖7、8)與一啟動位置（見圖1〇、u)之間移動，當 該觸壓部51被觸壓而移動該啟動位置時，該啟動開關5〇 可致動該擊釘件20沿該軸向X移動至將該出釘部u内的 釘子3 1擊出。 该扳機裝置60是樞設於該本體1〇並鄰近於該啟動開 關50，該扳機裝置60可相對於該本體1〇在一未擊發位置 (見圖7、8)及一擊發位置（見圖1〇、u)之間樞轉。 該扳機裝置60具有一與該本體1〇樞接的扳機件61、 一樞設於該扳機件61且與該觸壓部51抵接的傳力件62、 一設置於該扳機件61的定位銷63,及一設置於該定位銷 63的扭簧64。 該扳機件61具有一被驅動端部611、一相反於該被驅 動端部611的樞接端部612，及一設置於該樞接端部612的 推動部613。該推動部613具有二間隔設置的推動塊614。 該定位銷63是設置於該被驅動端部611。 邊傳力件62具有一可轉動地設置於該定位銷63的連 接端部621，及一相反於該連接端部621的抵接端部622。 該扭簧64的二支腳641是分別與該扳機件61、該傳力 10 200948554 件62抵接。 該保險裝置7〇具有一沿該軸向χ可移動地裝設於該本 體1〇 保險機構71、一沿該轴向χ可移動地裝設於該本體 10且可操作地與該扳機件61連接的閥件72、一彈性元件 73、二裝設於該閥件72上的第一密封環74、一裝設於該閥 件72上的第二密封環75，及一裝設於該閥件72上的第三 密封環76。 φThe rib 2 drives the cam member 4〇2 to rotate counterclockwise. However, since the movement of the shackle 401 will be limited by the predetermined distance D (see FIG. 2, the cam member 402 will restrict the plug member). The amount of downward movement of 8〇2 causes the seal ring 8〇3 on the plug 802 to move between the first and second openings 9〇4 and 905, thus, from the control air chamber 5〇1 The high pressure gas 602 flowing into the upper chamber passes through the first openings 9〇4, the communication space 9〇6, the second openings 9〇5, the lower chamber 9〇3 and the exhaust outlet 9 are discharged to the outside, causing a pressure drop in the control chamber 5〇1, and actuating the top inner seat 5 to move upward to open the piston chamber 1〇2, so that the high pressure gas in the gas storage chamber 602 can enter the piston chamber 1G2, and actuate the nail member 2 to strike the nail 301 in the nail portion ιοί, thereby nailing a metal connector 6〇4 to the workpiece 603. Conversely, As shown in FIGS. 5 and 6, when the first end portion 4〇3 of the safety member 4〇1 is not positioned within the predetermined distance d (see FIG. 距) from the workpiece 6〇3 and the valve stem 702 is triggered by the trigger 6 〇1 When pressed, the seal ring 7〇3 on the mast 7〇2 will move up to seal the chamber 7〇9, and (4) the high pressure gas 602 in the gas reservoir 断3 will pass through the first passage 7〇. 6 continues to flow into the chamber 7〇9. The seal ring 704 will move up to no longer seal the chamber, so that the second and third passages 707, 708 are interconnected. Thus, the body 602 will pass through the control air passage. 1 〇 4 The high-pressure gas in the control chamber 501, the second and third passages 707, 708, and the passage 9〇1' flow into the upper chamber 9〇2, and then push the plug 802 downward to drive The cam member rotates in a counterclockwise direction, however, since the movement of the safety member 401 is not restricted to the predetermined distance D (see Fig. 1), the cam member 4〇2 does not restrict the plug member 8〇. The amount of downward movement of 2 causes 7 200948554 to move the seal ring 8〇3 on the plug member 802 below the second opening 9〇5, and block the second openings 905 from communicating with the lower chamber 9〇3, In this way, the high-pressure gas 6〇2 in the control air chamber 501 cannot be discharged to the outside through the exhaust outlet, so that the control air chamber 5〇1 cannot generate sufficient pressure drop to actuate the The inner seat 5' is therefore unable to strike the nail 301 in the nailing portion 101. ❹ ❹ In short, the high-pressure gas 6〇2 in the control gas chamber 501 needs to pass through the trigger valve first. 7' re-flowing until the contact valve 8 pushes the plug member to drive the safety mechanism 4 to determine whether to actuate the nail member 2. [Invention] Therefore, the object of the present invention is to provide a gas storage chamber. The high-pressure gas is used to drive the insurance mechanism to determine whether to fire the pneumatically-safe nailing. The pneumatic safety type nailing of the present invention comprises a body, a nailing member, a starting switch, a trigger device, and a safety device.

The safety device has a safety mechanism that is axially movably mounted to the body, and a valve member movably mounted to the body in the axial direction and operatively coupled to the trigger device 8 200948554 The safety mechanism has a plenum disposed along the axial direction, the valve member having an air passage extending into the plenum 'when the trigger device is in the unfired position', the contact portion is in the unactuated position The air passage is in communication with the air reservoir. When the trigger device moves to the firing position, the trigger device drives the valve member to move along the axial direction to the air passage communicating with the air reservoir, the high pressure gas in the air reservoir. Flowing into the air chamber through the air passage to drive the safety mechanism to move along the axial direction. If the safety mechanism moves no more than a safety distance relative to the nail removal portion, the trigger device forces the pressure sensing portion to move to the starting position. The safety mechanism moves beyond the safety distance with respect to the nail ejection portion, and the pressure contact portion remains in the unactivated position.

The safety member 77 has a first end portion 771 adjacent to the nail ejection portion u, and a second end portion π connected to the cylinder member 78. The cylinder member 78 has a gas chamber 781 disposed along the axial direction X. The sinus valve member 72 has an intake end portion 721 adjacent to the plenum 13 and extending into the channel 14, an exhaust end portion 722 extending into the plenum 781, a pushed portion between the outlet ends 721, 722, and an air passage 724 extending from the intake end 721 to the exhaust end 722 along the axial direction. The driven portion 723 has a driven cam surface 725, and the pushing block 614 of the pushing portion 613 of the trigger member 61 abuts against the driven cam surface 725. The air passage 724 has a plurality of intake ports 726 disposed at the intake end portion 721 and an exhaust port disposed at the exhaust end portion 722. 27. The elastic member 73 is mounted in the air chamber 781, and both ends of the elastic member 781 abut against the cylinder member 78 and the exhaust end portion 1. The first seal ring 74 is mounted on the exhaust end 722 and can seal the air chamber 781. The second and third sealing rings 75, 70 are disposed at intervals along the axial direction X on the β air inlet end portion 721, and the air inlet 726 of the air passage 724 is interposed between the second and third sealing rings 75, Between 76. Ο 借此 By this, as shown in FIGS. 7 and 8, when the user does not press the trigger member 61, the contact portion 51 is in the unactuated position, the second end portion 771 of the safety member 77 and a workpiece 200. An insurance distance L can be defined therebetween. At this time, the second and third seal rings 75, 76 and the air inlets 726 are located in the channel ,, and the third seal ring 76 seals the channel 14 The air plenum 13 is blocked from communicating with the air passage 724 via the channel 14 , and the splicing end portion 622 of the force transmitting member 62 abuts against the gas absorbing member 78 . As shown in FIGS. 10 and 11, when the nailing portion u is directed to the workpiece 2 and the user presses the trigger member 61 to move to the firing position, the pushing block 614 of the trigger member 61 pushes the valve member 72. When the pushing portion 723 drives the valve member 72 to move along the axial direction X until the air passage 724 communicates with the air storage chamber U, ^, the third sealing ring 76 moves into the air storage chamber 13, The inlet 726 is moved to communicate with the sump 13 , and the second sealing ring 75 is still located in the channel 14 and seals the channel 14 . Thus, the south pressure gas 100 in the sump 13 is The air passage 724 can flow into the air chamber 78b and the xenon red member 78' drives the safety member 77 along the axial direction X toward the workpiece (four) at this time. 'Because the first end portion of the safety member 77 is affected by The limit distance "see Γ;) cannot move relative to the nailing portion 11 beyond the insurance as shown in Fig. 7), so that the abutting end portion (2) of the force transmitting member 62 can still be kept in contact with the hole member 78, When the trigger member 61 drives the transmission member 12 200948554 to force the pivot member 62 to the firing position, the force transmitting member 62 can be the fulcrum of the cylinder member 78, and the contact portion 5 is forced. 1 moving to the start position, the high pressure gas 100 (see FIG. 7) in the control air chamber 4 is discharged to the outside through the start switch 50, causing a pressure drop in the control air chamber 41, and actuating the The top inner seat 40 moves upward to open the piston chamber 12, so that the high-pressure gas 1〇〇 in the air storage chamber 13 can enter the piston chamber 12, and the nail is activated to the inside of the nail portion u. The nail 31 is struck out, and then a metal connector 300 is nailed to the workpiece 2. As shown in Figures 12 and 13, when the nail portion u does not point to the workpiece 2 (see Fig. 10) When the user presses the trigger member 61 to move to the firing position, the pushing block 614 of the trigger member 61 also pushes the pushed portion of the jaw to drive the valve member 72 along the axial direction to the air passage 724. Connecting the L gas storage chamber 13 such that the high pressure gas 100 in the gas storage chamber 13 also flows into the gas chamber 781, and pushes the cylinder member 78 to drive the safety member 77 along the shaft. Moving toward the cymbal, at this time, since the first end portion 771 of the securing member is not limited to the workpiece 200 (see Fig. 10), the heading portion U is The movement distance L (see FIG. 7) is exceeded, so that the abutting end 622 of the transmission member 62 will disengage the cylinder member 78 and be suspended. When the trigger member 61 drives the force transmitting member 62 toward The contact portion 51 moves I!: the contact portion 51 will bear against the force transmitting member 62, forcing the force transmitting member, the /X position pin 63 to swing counterclockwise for the center of the swing, so that the touch The pressure pin 51 will remain in the unactuated position i, and the nail member 20 will be moved. Further, as shown in Figs. 14, 15, when the user presses the trigger member 61 13 200948554 and the first piece of the safety piece 77 771 your 4 ° 1 moves beyond the fuse distance L (see the abutment end of the force piece 62 (2) has completely disengaged the cylinder: 78 'so 'if the first end 77i of the fuse 77 is in this state The externally pushed 'the gas is 7 s; the 〇a rolled piece 78 will only slide over the side of the abutting end 022, and the force transmitting member 62 cannot be driven at all, so that the pressing portion is It will remain in the unactivated position, and the nailing member 2 can be effectively prevented from bursting the nail 31.归 归 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple scope of the invention and the description of the invention.
