The pre-stressing effect causes the first end 211 of the sliding member 21 to illuminate the nailing opening 132, and the moving member 41 is pressed by the first acting member 34 to drive the buckle 43 to be displaced relative to the gun body 10, so that the buckle The guide shaft 432 of the 43 is separated from the joint portion 422a by the movable portion 421, and slides along the joint portion 422a to the positioning portion 422b of the disengagement portion 422, and the restricting portion 431 of the cleat 43 does not with the recess of the safety member 22. 221, the contact relationship of the two is released, so that the fuse unit 20 is no longer affected by the safety unit 40; at this time, the second action member 35 is pivoted by the second pivot point 37, so that the operating portion 351 is moved by the pressing portion 351b. To the relaxed section 351c, the valve stem 33 is again brought into contact with the relaxed section 351c, and the valve stem 33 prevents the valve body 32 from being electrically connected to the chamber, so that the trigger device 30 cannot fire the staple 1.

另外,於扣壓扳機裝置30之觸發器31時,操作部351之接觸段351a與閥桿33接觸,第二作用件35樞擺同時帶動第一作用件34之一端抵推移動件41,使移動件41帶動扣片43移動,保險件22受扣片43帶動而牽制滑座21移動,使滑座21之第一端211凸出擊釘口132,且未抵於物件2;此時,扣片43之導引軸432滑設置脫離區段422,彈性件44之兩端會頂推保險件22及作用槽411之內壁,而扣壓觸發器31之力量,並無法使第二作用件35之操作部351抵推閥桿33,造成閥體32無法與腔室導通,穿釘1不會被擊出;藉此,彈性件44之舒張預力能夠限制第二作用件35產生作用,以避免觸扳機裝置30而不慎擊發穿釘1之問題發生。In addition, when the trigger 31 of the trigger device 30 is pressed, the contact portion 351a of the operating portion 351 is in contact with the valve stem 33, and the second acting member 35 pivots while driving one end of the first acting member 34 against the pushing member 41 to move The piece 41 drives the buckle piece 43 to move, and the safety piece 22 is driven by the buckle piece 43 to move the carriage 21 so that the first end 211 of the sliding seat 21 protrudes from the nailing hole 132 and does not reach the object 2; at this time, the buckle piece The guide shaft 432 of the slider 43 is slidably disposed away from the section 422, and the two ends of the elastic member 44 push the inner wall of the safety member 22 and the action groove 411, and the force of the trigger 31 is pressed, and the second action member 35 cannot be used. The operating portion 351 pushes against the valve stem 33, causing the valve body 32 to be unable to be electrically connected to the chamber, and the piercing nail 1 is not knocked out; thereby, the relaxation pre-stress of the elastic member 44 can restrict the second acting member 35 from acting to avoid The problem that the trigger trigger device 30 accidentally hits the nail 1 occurs.

藉此,本創作透過扣片43之導引軸432於活動區段421及脫離區段422間移動,使保險單元20與扣片43間之連結關係產生變化,於確認槍體10已確實抵壓於物件2後,藉由移動件41產生反作用力於扳機裝置30,使扳機裝置30之閥體32與腔室導通,令氣壓源之壓縮氣體進入腔室,由壓縮氣體驅使撞釘件撞擊釘道131中之穿釘1,令穿釘1由擊釘口132擊出至物件2,藉以提升使用時之安全性。Thereby, the present invention moves between the movable section 421 and the disengagement section 422 through the guide shaft 432 of the clasp 43 to change the connection relationship between the securing unit 20 and the cleat 43, and confirms that the gun body 10 has indeed arrived. After pressing on the object 2, a reaction force is generated by the moving member 41 on the trigger device 30, so that the valve body 32 of the trigger device 30 is electrically connected to the chamber, so that the compressed gas of the air pressure source enters the chamber, and the compressed gas drives the impact member to collide. The nail 1 in the nail channel 131 causes the nail 1 to be struck out to the object 2 by the nailing hole 132, thereby improving the safety in use.

再者,本創作之結構簡單,使操控作動順暢,並且不會相互干涉,進而避免觸扳機裝置30而不慎擊發穿釘1之問題發生。Moreover, the structure of the present invention is simple, so that the manipulation is smooth and does not interfere with each other, thereby avoiding the problem that the trigger device 30 accidentally hits the nail 1 .
