What Are Tweezers?
Tweezers are tools with a small pinch that can be picked up with the tip of a finger. They are useful for handling small parts that cannot be handled with human fingers.
Uses of Tweezers
The primary use of tweezers is to perform small tasks. Examples include attaching electronic components, threading and sewing, grabbing hair and eyelashes, and surgical procedures.
Tweezers can be used to pick up and precisely position very fine objects or objects that cannot be grasped with the fingers.
Principle of Tweezers
The principle of tweezers is that by applying force, a small knob is opened and closed to pinch an object.
They consist of two arms. One arm is usually made up of a flat surface, while the other arm has a sloped shape with respect to the flat surface. When the tweezer is closed, this sloped arm rests against the flat arm, allowing it to pick up small nibbles.
Structure of Tweezers
Tweezers are generally constructed with a thin, pointed tip. This is to allow them to pick up small objects and get into tight places.
In addition, the arms of the tweezer may have ribs to prevent slipping and grooves for gripping. These structures allow for precise manipulation and help prevent the tweezer from slipping during use.
How to Choose Tweezers
There are many types of tweezers available, and it is important to choose the right one for your application.
1. Knob
Tweezers with a flat knob close the knob parallel to the flat surface, thus applying a constant pressure. Tweezers with a rounded knob close the knob against a rounded surface, thus applying pressure more evenly. Tweezers with an angled knob can be angled.
2. Material
Tweezers are also classified according to their material. For example, metal tweezers and plastic tweezers. Metal tweezers are durable and heat-resistant, making them suitable for handling hot objects or working with strong force. Plastic tweezers, on the other hand, are lightweight, easy to handle, and scratch-resistant, making them suitable for working with soft or delicate materials.
3. Shape
Tweezers are available in long and narrow or curved shapes. Elongated tweezers can enter and work in tight spaces and deep places. Curved tweezers are suitable for working in curved or hard-to-reach places.
Types of Tweezers
There are many different types of tweezers, depending on their use and shape. Among them, special tweezers are as follows:
1. Precision Tweezers
Precision tweezers are used for particularly small parts and precision work.
2. Vacuum Tweezers
Vacuum tweezers are a type of tweezer that uses the force of a vacuum to attract objects.
3. Hot Tweezers
Hot tweezers are repair tools that have a tweezer-like tip on the end of the tool.
4. Vacuum Tweezers
Vacuum tweezers are tools that use a vacuum to pick up objects.
5. Suction Tweezers
Suction tweezers are tweezers that use a pump or other suction force to pick up spherical or small parts that are normally difficult to grasp.
