可調(diào)式扭力扳手也叫預(yù)置式扭矩扳手，這款扳手具有預(yù)設(shè)扭矩?cái)?shù)值和聲響報(bào)警的特點(diǎn)，操作起來(lái)也是比較簡(jiǎn)單的，例如螺栓只需要擰10N.m的力，直接在扳手上設(shè)置，到達(dá)預(yù)設(shè)數(shù)值時(shí)，“喀嚓”聲響報(bào)警，停止用力即可，操作完成。
Adjustable torque wrench is also known as preset torque wrench. This wrench has the characteristics of preset torque value and sound alarm, and it is relatively simple to operate. For example, the bolt only needs to be screwed by 10N. M, and it can be set directly on the wrench. When the preset value is reached, the "click" sound alarm will sound, and the operation can be completed.
可調(diào)式扭力扳手組成及原理：
Composition and principle of adjustable torque wrench:
可調(diào)式扭力扳手一種以高壓氣泵為動(dòng)力源的扭矩扳手。是由一個(gè)或兩個(gè)有力的氣動(dòng)馬達(dá)來(lái)驅(qū)動(dòng)帶有三層或更多周轉(zhuǎn)齒輪的扭矩倍增器。 經(jīng)由調(diào)整氣體壓力來(lái)控制扭矩大小，為允許特定的扭矩需求設(shè)定，每臺(tái)工具都配有專(zhuān)用的氣壓先對(duì)扭矩的對(duì)照?qǐng)D表和校正報(bào)告。且為能更進(jìn)一步的應(yīng)用，氣動(dòng)扭矩扳手可同時(shí)搭配扭矩傳感器，時(shí)輸出的扭矩更。在獲得所需的扭矩后可使用合適的回路系統(tǒng)以手動(dòng)或自動(dòng)來(lái)關(guān)閉氣源。
The adjustable torque wrench is a torque wrench with high pressure air pump as power source. A torque multiplier with three or more epicyclic gears is driven by one or two powerful pneumatic motors. The torque is controlled by adjusting the gas pressure. In order to allow the specific torque demand setting, each tool is equipped with a special air pressure, and the torque comparison chart and calibration report are provided. For further application, pneumatic torque wrench can be combined with torque sensor at the same time, and the output torque is more. After the required torque is obtained, the air source can be closed manually or automatically by using a suitable loop system.
可調(diào)式扭力扳手是由兩部分組成的，扳手桿和可換頭。在下圖中我們可以看到只要確定扳手方隼的尺寸，就可以更換各式各樣的頭部，極大的拓寬了扭力扳手的工位需求。
Adjustable torque wrench is composed of two parts, wrench rod and replaceable head. In the figure below, we can see that as long as the size of the wrench square falcon is determined, all kinds of heads can be replaced, which greatly widens the working position requirements of torque wrench.

可調(diào)式扭力扳手是屬于高精密儀器的，有一些事項(xiàng)還是要注意下：
Adjustable torque wrench belongs to high precision instrument. There are some matters needing attention:
1、使用中請(qǐng)勿強(qiáng)烈沖擊。
1. Please do not make strong impact during use.
2、不能當(dāng)榔頭使用，敲擊工件。
2. Can not be used as a hammer, knock the workpiece.
3、扳手報(bào)警后請(qǐng)勿繼續(xù)施力。
3. Do not continue to apply force after the wrench alarm.
4、使用前請(qǐng)檢查扳手上的箭頭是否同施力方向一致，如果不一致請(qǐng)將扳手頭旋轉(zhuǎn)180度重新安裝。
4. Before use, please check whether the arrow on the wrench is consistent with the force application direction. If not, please rotate the wrench head 180 degrees to install again.
5、請(qǐng)勿自行拆卸扳手各部件，以免破壞精度影響使用。
5. Do not disassemble the parts of the wrench by yourself, so as to avoid damaging the accuracy and affecting the use.
6、預(yù)置式扭力扳手，使用完后，應(yīng)把扭力值調(diào)零位放置，以保持扳手精度，延長(zhǎng)使用壽命。
6. After using the preset torque wrench, the torque value should be adjusted to zero position to maintain the accuracy of the wrench and prolong its service life.
