手电钻上的s符号什么意思_电钻与冲击驱动器：有什么区别？

手电钻上的s符号什么意思

When it comes to home improvement projects, a power drill is one of the most common tools you’ll need. But an impact driver is perhaps an upgraded version that you should consider adding to your arsenal.

对于家庭装修项目，电钻是您需要的最常用工具之一。 但是，冲击驱动程序可能是升级版本，您应该考虑将其添加到军械库中。

Power drills and impact drivers are similar tools: both look a lot alike, and they both are able to drive screws into different materials. However, impact drivers make the work a lot easier.

电钻和冲击起子是相似的工具：两者看起来很相似，并且都能够将螺钉拧入不同的材料中。 但是，影响驱动程序使工作容易得多。

影响驱动程序做什么 (What Impact Drivers Do)

Here’s the main difference: Impact drivers utilize the same rotational motion that power drills use, but as you’re driving in a screw, impact drivers also mix in a hammering action that not only hammers down, but sideways. This makes it way easier to drive screws into tough materials, and it prevents the drive bit from slipping off the screw head, which could potentially strip the head and ruin the screw.

这是主要区别：冲击起子采用与电钻相同的旋转运动，但是当您用螺丝钻进时，冲击起子还会混合锤击动作，不仅锤击向下，而且向侧面倾斜。 这样可以更轻松地将螺钉驱动到坚硬的材料中，并且可以防止驱动钻头从螺钉头上滑落，这有可能剥落螺钉头并损坏螺钉。

If you’ve ever heard an impact driver in action, then you’ve probably noticed this in the form of a really loud, repetitive clicking noise that it makes as it’s driving in a screw. That’s the noise of the hammering action, and it occurs dozens of times per second, depending on how fast you’re driving in the screw.

如果您曾经听说过有冲击力的驾驶员在行动，那么您可能已经注意到它以非常大的，重复的咔嗒声的形式出现，这是它在拧入螺丝时产生的。 这就是锤击动作的声音，每秒发生数十次，具体取决于您拧入螺丝的速度。

With a power drill, you’d normally have to apply a lot of pressure in order to prevent the drive bit from slipping, but the hammering action of impact drivers mostly prevents this, and all you have to do is apply enough pressure to keep the screw guided and on point.

使用电钻时，通常必须施加很大的压力才能防止驱动钻头打滑，但冲击起子的锤击动作通常会阻止这种情况，而您所要做的就是施加足够的压力以保持螺钉引导并对准点。

Impact drivers are also great for removing stubborn screws or bolts when reversing the spin direction. The hammering action can make it easier to remove fasteners that corroded or were over-torqued.

反向旋转时，冲击起子也可用于去除顽固的螺钉或螺栓。 锤击操作可以使卸下腐蚀或过度扭转的紧固件更容易。

影响力驾驶员无法做什么 (What Impact Drivers Can’t Do)

If you end up getting an impact driver, it’s important to know that there are a few small disadvantages compared with power drills.

如果您最终获得了冲击起子，则必须知道与电钻相比，有一些小缺点。

First off, impact drivers really shouldn’t be used for precise drilling—your power drill will always do a better job at that since you don’t want a hammering action when drilling. Plus, power drills have a chuck, which is a device on the end of the drill that consists of claws that can open and close to accept all different sizes of drill bits. Impact drivers have a quick-change sleeve that only accept bits with 1/4-inch hex shanks. You can find drill bits with hex shanks, but they’re few and far between.

首先，确实不应该使用冲击起子进行精确的钻Kong-因为您不希望在钻Kong时进行锤击，因此电钻始终会做得更好。 另外，电钻具有一个卡盘，该卡盘是位于钻头末端的一种装置，由可以打开和关闭以容纳所有不同尺寸的钻头的爪组成。 冲击起子具有一个快速更换套筒，该套筒仅接受带有1/4英寸六角柄的钻头。 您可以找到带有六角柄的钻头，但它们之间相差无几。

Power drills also have two gears: one that’s slower with more torque for driving in screws, and a second gear that’s faster for drilling holes. Impact drivers only have one gear, so you have to be a bit more precise with the variable-speed trigger if using an impact driver.

电钻也有两个齿轮：一个速度较慢，扭矩更大，用于拧入螺丝；另一个齿轮则较快，用于钻Kong。 冲击起子只有一个挡位，因此如果使用冲击起子，则必须更加精确地使用变速触发器。

Power drills also have a clutch, which is similar to having a built-in torque wrench of sorts. It allows you to drive in a screw, without accidentally tightening it down so much that it blasts through the material. Instead, you can set it to a number and when it gets to a certain torque level, it will stop driving. Impact drivers don’t have clutches, so you’re at the mercy of your own strength and precision.

电钻还具有一个离合器，类似于具有内置的扭矩扳手。 它使您能够拧入螺丝，而不会意外将其拧得太紧，以至于无法穿透材料。 相反，您可以将其设置为一个数字，当达到一定的扭矩水平时，它将停止驱动。 冲击驱动器没有离合器，因此您只能靠自己的力量和精确度来摆布。

两者兼得 (Use Both for the Best of Both Worlds)

Contrary to what you might think, power drills and impact drivers actually complement each other rather than compete, so it’s best to have both tools in your tool box if possible—power drills are great for drilling and impact drivers are great for driving. In fact, many tool manufacturers sell power drill and impact driver combos, like this one.

与您可能想到的相反，电钻和冲击起子实际上是相辅相成而不是相互竞争，因此，如果可能的话，最好在工具箱中同时使用这两种工具-电钻非常适合钻Kong，而冲击起子也非常适合驱动。 实际上，许多工具制造商都出售电钻和冲击起子组合，就像这样 。

With that in mind, I always like to have a drill bit ready to go in my power drill, with a drive bit ready to go in my impact driver. That way if I’m drilling a lot of pilot holes, I can drill them using my power drill and then just quickly switch to my impact driver to drive in the screw—no need to constantly change bits in my power drill.

考虑到这一点，我一直喜欢在电钻中准备好钻头，并在冲击起子中准备好钻头。 这样，如果我要钻很多导向Kong ，则可以使用电钻钻Kong，然后快速切换到冲击起子以拧入螺丝-无需不断更改电钻中的钻头。
