Description
本創作係與氣動工具有關，特別是有關於一種氣動工具扳機結構。This creation is related to pneumatic tools, in particular to a pneumatic tool trigger structure.
習知之氣動工具是利用高壓氣體帶動氣動馬達中的轉子轉動，再利用氣動馬達帶動工具轉動，而可以用以轉動螺絲或其他工件。The pneumatic tool of the prior art utilizes high-pressure gas to drive the rotation of the rotor in the air motor, and then uses a pneumatic motor to drive the tool to rotate, and can be used to rotate the screw or other workpiece.
習知之氣動工具一般皆係配置有一扳機。一般作業中，常需要依據各種不同作業而有改變轉速及扭力之需求，而通常係透過於氣動工具之本體上另外形成供調速機構組設之結構，且需另外組配調速機構。習知氣動工具之進氣閥已有可供調整進氣流量者，藉由改變進氣流量，可調整氣動工具的輸出扭力值。例如，TWI342253及TWI332890所揭者即為此類氣動工具。Conventional pneumatic tools are generally equipped with a trigger. In general operation, it is often necessary to change the rotational speed and the torsion according to various operations. Usually, the structure for the speed regulation mechanism is separately formed on the body of the pneumatic tool, and a speed adjustment mechanism is additionally required. Conventional pneumatic tools have an intake valve that can be used to adjust the intake air flow. By changing the intake air flow, the output torque value of the pneumatic tool can be adjusted. For example, those disclosed in TWI342253 and TWI332890 are such pneumatic tools.
在TWI342253中，其主要於氣缸之一側設有複數組排氣孔，又缸筒之各排氣孔與本體排氣流道之間並設有一排氣流路切換構件，藉以切換排氣之氣流由該不同排氣孔進行排氣，達到扭力狀態可分段調整之效果。In TWI342253, a plurality of exhaust holes are arranged mainly on one side of the cylinder, and an exhaust flow switching member is arranged between each exhaust hole of the cylinder and the exhaust passage of the main body, thereby switching the exhaust gas. The airflow is exhausted by the different exhaust holes, and the effect of the torque state can be adjusted in stages.
在I332890中，其主要係依循該轉子正轉方向依序形成在氣流竄流路徑上且相隔一間距的至少一前置排氣孔與至少一後置排氣孔，其 中一控制閥是可在封閉該前置排氣孔的一第一位置與開通該前置排氣孔的一第二位置間變換位置，使氣流依循該轉子正轉方向由該後置排氣孔或提前由該前置排氣孔散失至該氣缸單元外，以選擇性集中或分散氣流，進而控制該轉子轉動時的扭力大小。In I332890, the main venting hole and the at least one rear venting hole are formed in the airflow turbulent path and spaced apart by a distance according to the forward rotation direction of the rotor. The first control valve is capable of changing a position between a first position for closing the front exhaust hole and a second position for opening the front exhaust hole, so that the air flow follows the forward direction of the rotor by the rear exhaust The hole is pre-dissipated from the front exhaust hole to the outside of the cylinder unit to selectively concentrate or disperse the air flow, thereby controlling the amount of torque when the rotor rotates.
然而，上述專利TWI342253及TWI332890之排氣流路切換構件或控制閥皆係獨立於扳機而另外設於氣動工具之本體上，故於氣動工具之本體上另外形成供調速機構組設之結構，且需另外組配調速機構，結構複雜、組配不易、成本較高，且較不便操作。However, the exhaust flow switching members or control valves of the above-mentioned patents TWI342253 and TWI332890 are separately provided on the body of the pneumatic tool independently of the trigger, so that a structure for setting the speed regulating mechanism is additionally formed on the body of the pneumatic tool. Moreover, the speed regulation mechanism needs to be additionally assembled, the structure is complicated, the assembly is not easy, the cost is high, and the operation is inconvenient.
因此，有必要提供一種新穎且具有進步性之氣動工具扳機結構，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive pneumatic tool trigger structure to solve the above problems.
本創作之一目的在於提供一種氣動工具扳機結構，可將段位或調速機構一體整合於該扳機結構中，無需於該本體另外形成供調速機構組設之結構，亦即不需變更現有之本體結構，其結構簡單、組配容易、成本亦可降低，且操作極為簡易、方便。One of the aims of the present invention is to provide a pneumatic tool trigger structure, which can integrate a step position or a speed governing mechanism into the trigger structure, without separately forming a structure for the speed governing mechanism, that is, without changing the existing one.

The set of positioning mechanisms are releasably positioned relative to each other. In detail, the set of positioning mechanisms includes, for example, a retractable elastic card assembly and a latch structure, and the elastic card assembly includes an elastic member disposed on the body 10 and a resisting body that is resiliently received by the elastic member. The cassette structure can be, for example, a recess, and the rod member 31 and the barrel member 20 can be positioned by the abutting body against the recess.
透過上述結構，氣動工具之扳機結構除發揮原本進氣啟、閉控制功能外，更因該段位或調速機構與該扳機結構一體整合為單一結構組 件，而構成同時兼具有轉速或扭力調整以及控制氣動工具作動與否功能之複合式扳機，無需於該本體另外形成供調速機構組設之結構，亦即不需變更現有之本體結構，其結構簡單、組配容易、成本亦可降低。Through the above structure, the trigger structure of the pneumatic tool not only functions as the original intake and closing control function, but also integrates the segment or the speed governing mechanism with the trigger structure into a single structural group. The composite trigger having the function of adjusting the rotational speed or the torque and controlling the operation of the pneumatic tool at the same time does not need to separately form the structure for the speed regulating mechanism, that is, the existing body structure is not required to be changed. The structure is simple, the assembly is easy, and the cost can be reduced.
此外，使用者只需簡單地透過轉動該桿件即可依據不同作業需求而調整所需段位，而使該氣動工具能以所需之動力大小或轉動快慢進行作動，極為方便。In addition, the user can simply adjust the required position according to different operation requirements by simply rotating the rod, so that the pneumatic tool can be operated with the required power size or rotation speed, which is very convenient.
