一、扭矩扳手的正確使用
1、 Correct use of torque wrench
1.扭矩扳手的施加扭矩的過程以及結構：用扭矩扳手施加扭矩時，通過與扭矩扳手的棘輪頭穩固連接的套筒連接需要施加扭矩的螺母/螺栓，手掌握在扭矩扳手手柄上的有效刻度線，順時針或逆時針加力，這個力帶動螺母/螺栓，當螺母/螺栓緊固，并所帶的扭矩與扭矩扳手設定的扭矩相等時，扭矩扳手的棘輪帶動扭矩扳手的頭部，把扭矩傳遞到觸發器，觸發器向右側滑動（卸力）。當滾柱碰到管后，會發出“咔噠”的信號，聽到信號后立即停止加力，取下扭矩扳手，即完成施加扭矩過程。
1. The process and structure of torque application of torque wrench: when applying torque with torque wrench, the nut / bolt required to be applied torque is connected through the sleeve firmly connected with the ratchet head of the torque wrench. The palm of the hand holds the effective scale mark on the handle of the torque wrench, and applies force clockwise or anticlockwise. This force drives the nut / bolt. When the nut / bolt is tightened, the torque and torsion are carried When the torque set by the torque wrench is equal, the ratchet wheel of the torque wrench drives the head of the torque wrench to transmit the torque to the trigger, and the trigger slides to the right (unloading force). When the roller touches the pipe, it will send out a "click" signal. After hearing the signal, stop the force application immediately and take down the torque wrench to complete the process of applying torque.
2.扭矩扳手設定值調整大致有2種形式：
2. There are two ways to adjust the setting value of torque wrench
其一，屬于預調式扭矩扳手的調整方法。松開尾部鎖夾，根據需要的設定值旋轉尾部的補助分度輪（順時針增加扭矩，逆時針減少扭矩，使分度輪的刻度與扭矩扳手得設定值相符，扭矩扳手校驗儀校驗。
First, it belongs to the adjustment method of the preset torque wrench. Loosen the tail lock clamp, rotate the auxiliary indexing wheel at the tail according to the required setting value (increase the torque clockwise and reduce the torque anticlockwise, so that the graduation wheel scale is consistent with the set value of the torque wrench, and the torque wrench calibrator is calibrated.
其二，屬于定值式扭矩扳手的調整。松開后蓋，相應得六角匙松開鎖緊螺釘，調整工具旋轉推壓環設定一個扭矩值，用扭矩測試儀校驗扭矩，固鎖緊螺釘，鎖緊后蓋。
Second, it belongs to the adjustment of fixed value torque wrench. Loosen the back cover, loosen the locking screw with the corresponding hexagon key, set a torque value by rotating the push ring of the adjusting tool, and then use the torque tester to verify the torque, fix the locking screw and lock the rear cover.
3.扭矩扳手的使用方法：施加扭矩時，手握在扭矩扳手手柄的中間刻度線位置。方頭與套筒、螺母/螺栓穩固連接（對開口/梅花系列扭矩扳手，應將開口/梅花頭完全插入/沉入螺母中），只能在扭矩扳手標注的方向上施力，同時施力方向應在±15度內（水平方向和垂直方向）。施力時應緩慢和平穩，切忌沖擊力。當聽到“咔嗒”聲后立即停止。
3. How to use the torque wrench: when applying torque, hold it at the middle scale of the handle of the torque wrench. The square head shall be firmly connected with the sleeve, nut / bolt (for the open / plum series torque wrench, the open / ring head shall be completely inserted / sunk into the nut), and the force can only be applied in the direction marked by the torque wrench, and the force application direction shall be within ± 15 degrees (horizontal direction and vertical direction). The force should be applied slowly and stably without impact force. Stop immediately when you hear a "click".
