一、扭力扳手有哪些種類
1、 What kinds of torque wrenches are there
1、按動力源可分為：電動扭力扳手、氣動扭力扳手、液壓扭力扳手及手動扭力扳手;
1. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench;
2、按測量原理可分為：預置式、示值式、指針式、數(shù)字式、電子式以及定值式扳手。
2. According to the measurement principle, it can be divided into: preset wrench, indicating wrench, pointer wrench, digital wrench, electronic wrench and fixed value wrench.
二、預置式扭力扳手的特點
2、 Characteristics of preset torque wrench
預置式扭力扳手具有預設扭矩數(shù)據(jù)和聲響裝配。當緊固件的擰緊扭矩達到預設數(shù)據(jù)時，能自動拍發(fā)訊號"卡嗒"(click)的一聲，同時伴有明顯的手撫摸時的感覺振動，提示工作完成。解除有效用力后，扳手各相關零件能自動復位 。
Preset torque wrench has preset torque data and sound assembly. When the tightening torque of the fastener reaches the preset data, it can automatically send a signal "click", accompanied by obvious sensory vibration when touching, indicating that the work is completed. After releasing the effective force, all relevant parts of the wrench can be reset automatically.
可手動精確設定扭矩值;手柄人體工程學優(yōu)化設計，握持舒適，大大降低高強度操作時產(chǎn)生的疲勞感。
The torque value can be accurately set manually; The ergonomic optimization design of the handle makes it comfortable to hold, greatly reducing the fatigue caused by high-intensity operation.
