The pneumatic power tool 10 has a gun-shaped housing 11 , a drive shaft 12 , and a trigger 13 . A lock member (not shown) can be mounted on the front end of the drive shaft 12 . The lock member is a bolt or a nut. . In addition, the trigger 13 is used to illuminate an air intake device (not shown) installed inside the casing 11. When the trigger 13 is pressed, the drive shaft 12 rotates.
此外,於殼體11的後方則設置有一旋鈕141,藉由調整該旋鈕141可控制驅動軸12的轉向,例如將旋鈕141順時針旋轉一預定角度後,可使驅動軸12順時針旋轉,若將旋鈕141逆時針旋轉一預定角度後,則可使驅動軸12逆時針旋轉。In addition, a knob 141 is disposed at the rear of the housing 11. The steering of the drive shaft 12 can be controlled by adjusting the knob 141. For example, after the knob 141 is rotated clockwise by a predetermined angle, the drive shaft 12 can be rotated clockwise. After the knob 141 is rotated counterclockwise by a predetermined angle, the drive shaft 12 can be rotated counterclockwise.
請參照圖2,圖2所繪示為氣動工具機的部分零組件,由左至右分別為:氣缸15、進氣閥16、與調整機構14。其中,於氣缸15內部設有葉輪(未繪示),葉輪上設置有葉片,進氣閥16則包括前蓋161與後座162,而調整機構14則包括旋鈕141與連動件142。在圖2中,除了旋鈕141外,其他的零組件皆位於殼體11的內部。藉由轉動旋鈕141,可連帶使連動件142與進氣閥16轉動。此外,氣缸15的後端還設置有正轉進氣孔與逆轉進氣孔(未繪示),藉由旋轉前蓋161可使正轉進氣孔或逆轉進氣孔開啟或封閉,以控制氣缸15內部葉輪的轉向,從而控制驅動軸12的轉向。Please refer to FIG. 2 , which is a partial component of the pneumatic machine tool, from left to right: the cylinder 15 , the intake valve 16 , and the adjustment mechanism 14 . An impeller (not shown) is disposed inside the cylinder 15 , a vane is disposed on the impeller, the intake valve 16 includes a front cover 161 and a rear seat 162 , and the adjustment mechanism 14 includes a knob 141 and a linkage 142 . In FIG. 2, in addition to the knob 141, other components are located inside the housing 11. By rotating the knob 141, the link 142 and the intake valve 16 can be rotated. In addition, the rear end of the cylinder 15 is further provided with a forward rotation air inlet hole and a reverse rotation air inlet hole (not shown). By rotating the front cover 161, the forward rotation air inlet hole or the reverse rotation air inlet hole can be opened or closed to control The steering of the internal impeller of the cylinder 15 controls the steering of the drive shaft 12.
當氣動工具機10在運作時,其產生的震動可能讓進氣閥16偏離原本預定的角度,導致氣動工具機10無法有效運作。為了使進氣閥16保持在預定的角度,目前的作法是將後座162上的O型環1621與殼體11的內壁作緊密地接觸。藉由殼體11與O型環1621間的摩擦力,可使進氣閥16保持在預定的角度。然而,當殼體11與O型環1621間的摩擦力愈大,使用者也須花費更大的力量來轉動旋鈕141,從而造成使用上的不便。而且,O型環1621屬於軟性材質,使用時間愈久,磨損的問題也愈嚴重。When the pneumatic machine tool 10 is in operation, the vibrations generated may cause the intake valve 16 to deviate from the original predetermined angle, resulting in the pneumatic machine tool 10 not functioning effectively. In order to maintain the intake valve 16 at a predetermined angle, it is currently practice to bring the O-ring 1621 on the rear seat 162 into intimate contact with the inner wall of the housing 11. The intake valve 16 can be maintained at a predetermined angle by the friction between the housing 11 and the O-ring 1621. However, as the friction between the housing 11 and the O-ring 1621 is greater, the user has to spend more effort to turn the knob 141, resulting in inconvenience in use. Moreover, the O-ring 1621 is a soft material, and the longer the use time, the more serious the problem of wear.
因此,如何設計出一氣動工具機,其可方便地讓使用者變換驅動軸之旋轉方向,以成為本領域具有通常知識者值得去思量的一個問題。Therefore, how to design a pneumatic machine tool that can easily change the direction of rotation of the drive shaft by the user is a problem worthy of consideration in the art.

The triggering member is disposed above the housing, and the sliding groove is disposed on one side of the pulling member, and the elastic member applies an elastic force to the pulling member. The connecting shaft penetrates the trigger member, and one end of the connecting shaft is inserted into the blind hole. When the trigger member is pulled, the connecting shaft is driven, so that the connecting shaft drives the intake valve to close or open the forward air inlet or reverse the air inlet.
而且,進氣閥包括一前蓋與一後座。藉由轉動前蓋可封閉或開啟正轉進氣孔或逆轉進氣孔,以調整氣動工具機之轉向。另外,後座與前蓋固定連接,且盲孔是設置於後座上。此外,切換機構更包括一支撐套環,該支撐套環位於盲孔的正上方且承靠在進氣閥上。彈力元件是套設於支撐套環上,而連接軸則貫穿支撐套環。Moreover, the intake valve includes a front cover and a rear seat.

Therefore, when the knob is rotated, the linkage is driven, so that the linkage drives the intake valve to close or open the forward intake or reverse the intake.
由於本發明之氣動工具機是利用卡合的方式來固定進氣閥,故可長久使用,不會像習知的O型環有磨損的問題。而且,由於並非利用O型環的摩擦力來固定進氣閥,故相較於習知的氣動工具機,使用者無須耗費較大的力量來轉動旋鈕或扳動件。Since the pneumatic machine tool of the present invention fixes the intake valve by means of the engagement, it can be used for a long time without the problem of wear of the conventional O-ring. Moreover, since the intake valve is not fixed by the frictional force of the O-ring, the user does not need to use a large amount of force to turn the knob or the trigger member compared to the conventional pneumatic machine tool.

In the present embodiment, the intake valve 35 is also prevented from being deviated by the engagement, so that the O-ring 1621 (shown in Fig. 2) is not worn as is conventional. Moreover, the user can easily pull the trigger member 3611 without spending a large amount of force.
另外,上述所述的實施例中,氣動工具機的殼體皆呈槍形,但其實氣動工具機的殼體並不限於槍形,上述實施例的切換機構也可適用於其他形態的氣動工具機。請參照圖8,圖8所繪示為本發明之第三實施例的氣動工具機。此氣動工具機40的機殼41是呈筆直的形狀,其內部各元件(包括:切換機構36)與上述之第二實施例類似,故不再贅述。In addition, in the above-mentioned embodiments, the housings of the pneumatic machine tool are all gun-shaped, but the housing of the pneumatic machine tool is not limited to a gun shape, and the switching mechanism of the above embodiment can also be applied to other forms of pneumatic tools. machine. Please refer to FIG. 8. FIG. 8 illustrates a pneumatic power tool according to a third embodiment of the present invention. The casing 41 of the pneumatic power tool 40 has a straight shape, and its internal components (including the switching mechanism 36) are similar to the second embodiment described above, and therefore will not be described again.
