More specifically, this application relates to a hand-held rotary power tool, which has a balanced weight distribution, and has a tight weight distribution. Easy to use performance. [Previous technology] Hand-held rotary power tools are extremely common. There are two types of such tools in the market, grip-type rotary tools and right-angle rotary tools. The two types of tools differ greatly in their overall positioning. The standard gun-type rotary tool has a motor, a gear box, and an output truck, all of which are aligned in a casing; = 1 and a handle hangs from the rear of the casing. The right-angle rotation tool is positioned more vertically for use in a confined space. The right-angle rotation tool has a motor aligned vertically with the gearbox inside the handle, and the output shaft extends horizontally from the gearbox. One of the disadvantages of the grab rotary tool is that it is quite unbalanced. Most of these drills are heavily loaded with a rotary tool, which is basically the heaviest component, the gearbox and the motor, positioned in the forward position of the handle. This situation produces rotational torque on the handlebars behind the drill. Applying force to block the rotational torque generated by the front-end load will fatigue the user's hands and cause improper use of the tool. The use of the right-angle turning tool is basically applied to the working space where the gun-type rotating tool cannot be used. The disadvantage of these tools is that they are generally not easy to operate. This is because the motor is basically positioned in the handle part of the tool, forcing the handle to be more comfortable than the ergonomic expectation that it can be comfortably held by the user's hand. 72189-930609.doc -6-M248576 5. The right-angle rotation tool is basically not more expensive than the grip-type rotation tool. With this, these tools are for professional use only. [New content] a. Therefore, the general purpose of this application is to provide a hand-held power tool, which can avoid the disadvantages of the previous design and further provide additional structural and operational convenience. -An important feature is the provision of a hand-held rotary power tool, which is relatively balanced, thereby reducing the rotational torque on the handlebar. Another important feature is the provision of hand-held rotary power tools, which are compact and easy to use. Another important feature is the provision of hand-held rotary power tools, which are ergonomically designed to be comfortably held by the user's hand. [Embodiment] As shown in FIG. 1, a specific example of a rotary power tool 10 with one hand includes a casing 11 with an upper end portion 12, a handle portion 13 and a bottom portion M, which are placed in a Relative T-shaped structure. The handlebar part 13 and the bottom part 14 extend longitudinally to the upper end part 12, the handlebar part 13 is located between the upper end part 4 and the four part 13 include-a human body Iology holding ^ 19 with height The undulating surface is suitable for putting the user's hand around it. A chuck 15 extends forward from the upper end portion 12 and is provided with jaws 丨 6 for a fixing tool drill. A trigger 17 extends forward from the handle portion 13 for controlling the operation of the motor. A reverse shuttle 18 extends intermediately to the upper end portion 12 and the hand 13 for controlling the rotation direction of the motor. Knife Referring to FIG. 2, a motor 22 is disposed in a bottom portion μ of the housing u. 72189-930609.doc M248576 The input shaft 21 is rotatably combined with the motor 22, and extends from the motor 22 through the handle portion 13 'and finally rotatably couples a gear box 20 located at the upper end portion 12 of the housing 11. An output shaft 24 can also be rotatably combined with the gear box 20. The output shaft 24 extends therefrom at an angle which is substantially perpendicular to the longitudinal axis of the input shaft 21. The output shaft 24 extends from the upper end portion 12 of the housing U and is combined with the chuck 15 for rotation there. A switch assembly 23 is combined with the trigger 17 and is electrically connected to the motor 22 with a circuit for starting there. The switch combination 23 is disposed on the upper edge portion of the handle portion 丨 3. The shuttle 18 is located directly above the switch assembly 23, between the upper end injury 12 and the handle portion 13. The direction shuttle 8 is also combined with the motor in a known manner, where the direction of rotation is controlled. An electric wire 25 is provided along the bottom part wound 14 'and may also be electrically conductively combined with the motor 22 to supply electric power thereto. As shown in Figures 2 and 3, the rotary power tool 10 is designed for optimal one-handed operation. The length of the input shaft 21 allows the motor 22 to be placed below the handlebar portion 13 'so that the handlebar portion 13 is appropriately and ergonomically designed to be thin enough to be comfortably held by the user's hand . The handle part 1 3 may include a ergonomically designed grip part 19 to provide a safe and comfortable positioning for the relationship between the human hand and the drill. The grip portion 19 has a contoured surface that conforms to the surface of the palm of a human hand. The axis defined by the handle portion 13 and the input shaft 21 can be bent and disassembled at an angle of about 15 degrees to adapt to the natural angle of the human hand when it is applied to the drill. In addition, the trigger 17 and the direction shuttle 18 are positioned so that the tip of the finger is relatively easy to access the grip portion 9 of the hand. 72189-930609.doc M248576
附加於此旋轉動力工具10之最適宜之單手設計，為此裝 置之相對平衡。殼體之τ型結構可使工具之重量有效地分 佈，以降低因重量而產生於手把之旋轉扭力。殼體n之結 構使旋轉工具10中最重之配件，亦即齒輪箱2Q與馬達22， 於使用中實際地垂直對齊，以降低旋轉扭力。再者，馬達 22之定位於手把部份13之下，藉提供—抵銷力於炎頭15而 進-步減少旋轉扭力。任何由殼體u之上端部份12中組件 之重量，於軸心21前端所產生之旋轉扭力，將由設置於殼 體11之底部部份14中組件之重量予以抗拒。 本旋轉工具之設計之再一優點為，馬達22之定位於手把 部份13之下’降低上端部份12之長度，以提供緊適易用之 性能。The most suitable one-handed design attached to this rotary power tool 10 is relatively balanced for this device. The τ-shaped structure of the casing can effectively distribute the weight of the tool to reduce the rotational torque generated by the handle due to the weight. The structure of the housing n enables the heaviest accessory in the rotary tool 10, that is, the gear box 2Q and the motor 22, to be actually vertically aligned in use to reduce the rotational torque. Furthermore, the positioning of the motor 22 under the handlebar portion 13 further reduces the rotational torque by providing-offset force on the Yan head 15. Any rotational torque generated by the weight of the components in the upper end portion 12 of the housing u at the front end of the shaft center 21 will be resisted by the weight of the components provided in the bottom portion 14 of the housing 11. Another advantage of the design of the rotary tool is that the positioning of the motor 22 below the handle portion 13 'reduces the length of the upper portion 12 to provide a compact and easy-to-use performance.
