Portable hand drills are not usually considered very hard to use. For the most part, they are designed for anyone to be able to charge them, press the trigger, and start working – and they even come with an extra guide teaching you which nail is the most appropriate for each purpose.
隻要一切正常正常工作，這一切都保持了真實。但想象一下：你正試圖掛著一個相框，並且為了正確地做到這一點，你需要在牆壁上鑽兩個洞。你的手鑽花了幾個月鎖在抽屜裏，已經幸存下來了。但是，一旦你試圖讓釘子開始移動，隻需點擊即可出去。

了解鑽頭的不同部分
So what happened here? Do you know how to check if anything moved out of place? How well do you understand the way your drill works? Can you describe what’s wrong with a technician over the phone? Before you can do any of these things, you will need to know what each part does and what it’s called.
Most hand drills look a bit like a futuristic handgun. Because of this, we will be starting this tour from the smoking side – the point where the drilling nail is hooked onto.
檢查下麵的圖表，演示了鑽頭的許多部分。
ch
卡盤是鑽頭的一部分，在旋轉時緊緊地保持釘子。截至幾年前，大多數夾頭都有定製的夾頭，這些卡盤是隻能在自己的集合中融合釘子。如今，人們麵臨替代零件的理所當然。因此，Chucks現在帶有普遍的金屬尖頭，從內部抓住你的指甲（或位）。
通過這種方式，您隻需逆時針旋轉位以防止它或順時針才能刪除它。作為一個增加的安全措施，大多數手鑽也有一個內部棘輪，即在正確插入釘時單擊。如果它仍然鬆動，鑽頭將無法開始轉動。
離合器項圈
在夾頭後麵，你會發現一個更厚的旋轉衣領，將這個尖端與鑽頭的其餘部分加入。離合器套接環的工作與汽車的離合器踏板有很大關係：它允許您調整鑽頭將使用的扭矩（以及程度，齒輪）。
In many models, you can also find a dial or a set of numbers etched onto the clutch collar. As a general rule, a lower number means a “lower” gear (and a bit that spins at a slower speed).
Clutch collars can occasionally jam and prevent the drill from working properly.
Gear Selection Switch
根據型號，您的鑽孔可能沒有旋轉離合器套環，而是使用檔位選擇開關。在非常高的模型中，您會發現這兩者。在這些情況下，您的主齒輪將由此開關確定，套環隻會增加更精確的控製。
發動機
The thickest part of your drill is almost always going to be the motor. This will take up the “butt” of the gun.
在許多方麵,電機不需要太大的explanation. This is what powers your drill, and it will usually connect with your power source on the bottom. Yet, when the motor breaks, the chances are that you will need to enlist a professional’s help in order to fix it.
Speed Trigger
速度觸發器通常位於與槍支觸發相同的位置。這隻是因為它是一個非常直觀的地方，而不是因為設計師常規角色扮演銀行搶劫與他們的創作。
當您按速度觸發時，該位應開始轉動。基本鑽頭模型隻會在積極推動觸發時旋轉。然而，有些型號還包括鎖定機製，防止手指疲倦。
LED Light
Some models will emit light whenever they are on. This light most likely comes from a small LED bulb located right next to the trigger or directly on top of it.
The purpose of this light is not to let you know when the drill is in operation (this would be unnecessary, as the noise is hard to miss). Instead, it is meant to help you whenever you are drilling in a dark place. It should point directly towards the chuck and nail.
Rocker Switch
Many models include a smaller rocker switch close to the trigger. This is a safety feature that helps control the chuck. Often, when the chuck doesn’t have an automatic ratchet that locks the nail in, it will have a rocker switch instead.
翻轉它，您會將卡盤固定到特定方向 - 順時針或逆時針方向。這將阻止您意外取出針或在仍鬆散時打開鑽孔。
Grip or Handle
抓地力不僅僅是一個良好的，舒適的地方，可以握住你的手鑽。它還有助於將電機或發動機與電源連接。
在大多數模型中，用符合人體工程學的線條羅紋或蝕刻手柄，意味著提供安全的握把並實現更精確的運動。此外，許多型號還具有手柄頂部的塑料或橡膠覆蓋物。有些是專門製作出振動或防止出汗的手 - 當您處理快速變化的尖銳物體時可能是危險的
電池
立即在手柄下方，您將找到為發動機提供動力的電池。如果您的型號使用可更換電池，那麼電池將看起來像一個稍長的塑料部分，您可以鎖定在手柄的底部。
In models with one-piece, rechargeable batteries, you may find a mount instead. This will allow you to plug the hand drill directly onto the power source via a regular plug or AC/DC adapter.
結論
Learning the different parts of your drill will help you troubleshoot it whenever necessary, or at least to ensure that everything is complete and working properly. If your hand drill breaks, and you aren’t able to repair it yourself, this knowledge will help you understand what’s going on whenever the technician orders expensive new replacement parts. This is the kind of knowledge that saves money!
