The Difference between A Ratchet Wrench and A Torque Wrench

The scaffold ratchet podger spanner 21mm is connected by a main plum blossom sleeve of different sizes and is connected from the plum sleeve by the female key and the male key of the hinged key. A plum blossom sleeve has two plum-shaped through holes.

The movable trigger can easily adjust the angle of use of the wrench. The wrench is used for the tightening operation of the screw, and has the characteristics of strong applicability, convenient use and low cost.

Torque wrenches are also called torque wrenches or torque wrenches. Torque is the product of force and distance. When tightening screw fasteners such as screw bolts and nuts, it is necessary to control the amount of torque applied to ensure that the threads are tightened and the thread is not broken due to excessive torque, so use a torque wrench to operate. First set a required upper torque limit. When the applied torque reaches the set value, the wrench will make a “Kata” sound or the wrench joint will bend a little. This means that it has been tightened and you do not to need to strengthen it.

The difference is that the torque of the torque wrench can be set.

The principle of a torque wrench (torque wrench) that emits a kata sound is very simple and can be divided into the following steps to understand:

1. After the torque of the “Kata” is issued, the torque wrench indicates that the torque value you have requested has been reached;

2. The “Kata” issued by the torque wrench is generated by its own internal torque release structure. Its structure is divided into three structures: pressure spring, torque release joint and torque jack.
