Nowadays, more and more intelligent and electronic tools have entered thousands of households, profoundly changing people's lifestyles. Although the application of electronic tools is becoming more and more widespread, the importance of hand tools is still irreplaceable in some work. The most commonly used hand tools are screwdrivers and wrenches. Whether it is installation, maintenance or parts removal, we will need to use various types of wrenches to assist us in completing our work.
Among the types of wrenches, we may be more familiar with adjustable wrenches, combination wrenches, plum wrenches, torque wrenches, etc. These wrenches are similar in their use, and the main difference is that they are used in different situations. Below we will focus on the differences in the use of ordinary wrenches and ratchet wrenches and how to choose between the two.
Ordinary wrenches are like adjustable wrenches and combination wrenches. Their design structure is relatively simple. They all ensure that the main structure remains unchanged, and different shapes of wrenches are designed at both ends. Different wrenches can be used for different parts, and then the lever principle is used to easily tighten or loosen nuts, bolts and other fastener parts.
Compared with ordinary wrenches, the structural design of ratchet wrenches is much more complicated. First of all, the ratchet wrench has special parts such as ratchets, pawls, springs, etc. designed in the main head of the ratchet wrench, which can be used for certain special working conditions. The main design structure of the ratchet consists of a ratchet body and an isolation sleeve. The isolation sleeve is actually a circular ring with an external groove, which is generally installed on one side of the ratchet body.
Comparison of the characteristics of ordinary wrenches and ratchet wrenches
1. The operation method of ordinary manual wrenches is simple, which is suitable for the loosening and tightening operations of most ordinary parts, but it is more laborious to work for a long time.
2. The structure of the ratchet wrench is complex, which is suitable for parts that are difficult for ordinary wrenches to reach in for operation, and the ratchet wrench head is connected to the main end in a rotating manner.
How to correctly choose ordinary wrenches and ratchet wrenches?
The choice of the two wrenches needs to be determined according to the specific use environment. This is because different types of wrenches have different tensions and torques, and the shape of the parts to be operated also determines the shape of the head of the selected wrench. Therefore, we need to comprehensively consider various practical usage factors to achieve the correct selection of wrenches, so as to maximize work efficiency.
