圖11所示），並抵觸於加工物80表面，此時長釘71釘頭 711接受該梯面171止擋，因此長釘71不會縮入擊釘槽17 内，同時敲擊座61未接觸工件8表面；當使用者壓扣扳機 44驅動扳機閥4開闊時(如圖13所示），集壓室10之高壓空 氣會經由進氣通路45及前段流道111進入進氣口 51，壓迫 受力端面541以驅動閥栓54下移，促使閥栓54之推觸面 540向下推抵安全滑桿6頂部62，進而驅動安全滑桿6底 端敲擊座61下移至加工物80上方之預設高度h範圍内接 受工件8表面止擋（如圖11 a所示），該預設高度h係包括適 用於本釘槍之工件8厚度或穿孔81深度，該導氣孔530設 於頸孔531内之位置及閥塞542與導氣孔530之間的相對 位置，係專為配合該預設高度h而設計；如此，藉由圖11 a 之長釘71尖端712與敲擊座61底面之間的相對距離反應 穿孔81深度，並於該穿孔81深度符合該預設高度h之設 定範圍時，促使閥栓54接受該底端下移至預設高度h之安 全滑桿6的止擋，令閥塞542位移至導氣孔530下方的頸 孔531内，開啟進氣口 51與排氣口 52相連通，並阻斷進 氣口 51與底層氣室56相連通，致使控制閥5開閥，以導 引高壓空氣進入後段流道112内，並導入主氣閥2之主氣室 15 200942376 24内（如圖14所示），驅動滑套22帶動下閥門23上移而開 啟通氣孔21，並帶動上閥門25上移而關閉洩氣通道27， 促使集壓室10之高壓空氣經由通氣孔21進入上層氣缸室 31内，驅動活塞30帶動擊釘桿33下移擊發長釘71，致使 長釘71自穿孔81被釘入加工物80上（如圖12所示），以固 定工件8於加工物80上；該活塞30下移期間，下層氣缸 室32内之一部分空氣會經由氣孔34進入回程氣室15内， 另一部分空氣會經由搶體1底部之一洩氣孔16排放至外 界。上述擊釘桿33於下移至擊釘槽17内撞擊長釘71釘頭 711期間，由於擺動件9已擺動止擂部91彈性樞離擊釘槽 17之擊釘路徑，因此不會造成擊釘桿33誤擊擺動件9之狀 況0 當使用者放鬆扳機44時（如圖15所示），集壓室10 内之高壓空氣會驅動梭動閥41上移，以關閉進氣通路45 並開啟排氣通路46，使集壓室10之高墨空氣無法經由扳機 閥4持續進入主氣流道11、控制閥5及主氣室24内，且主 氣室24、主氣流道11及控制閥5内之高壓空氣會經由排氣 通路46排放至外界，致使上層集壓室101集結之高壓空氣 再次驅動滑套22帶動下閥門23下移而關閉通氣孔21 (如 圖16所示），並帶動上閥門25下移而開啟洩氣通道27，促 使上層氣缸室31内之剩餘氣體經由洩氣通道27及洩氣口 14排放至外界；期間，集壓於回程氣室15内之空氣會經由 氣孔34進入下層氣缸室32内，以驅動活塞30上移復位。 此外，若工件8之厚度或穿孔81的深度大於預設高度 h時，會縮短安全滑桿6可下移的行程；此時，使用者壓扣 16 200942376 板機44 .i£動板機閥4開閥（如圖17所示），集屢室1 〇内 之高壓空氣仍會經由進氣通路45及前段流道1Π進入進氣 口 51，以驅動閥栓54下移，進而驅動安全滑桿6底端敲擊 座61下移至未達該預設高度h的位置接受工件8止擋，同 時閥栓54接受該底端下移至未達預設高度h之安全滑桿6 的止擋，令閥塞542位移至導氣孔53〇上方的頸孔531内， 阻斷進氣口 51與排氣口 52及進氣口 51與底層氣室％相 連通，致使控制閥5關閥，以關閉主氣流道u，進而制動 〇 釘搶擊發釘件。 另外，若工件8之厚度或穿孔81的深度小於該預設高 度h時，會增長安全滑桿6可下移的行程；此時，使用者 壓扣扳機44驅動扳機閥4開閥（如圖18所示），集壓室1〇 ，之高壓空氣也會經由進氣通路45及前段流道lu進入進 f 口 51 ’以驅動閥栓54下移，進而驅動安全滑桿6底端敲 名j 61下移至超越該預設高度h的位置接受工件8止擋； 同時，該底端下移至超越該預設高度h之安全滑桿6會釋 〇放閥栓-54下移，令閥塞542位移至通孔说内，開啟進氣 口 jU雙由頸孔53卜通孔532與底層氣室％相連通，以導
