A clamp is a tool that allows you to hold or grab something.
Pinch is a term that comes from the French language ( pince ) and is used to name the tool that, thanks to its design, allows you to grab or hold a thing between its ends .
The operation of the clamp obeys the logic of simple levers : when you exert force on the handles of the tool, its tips close, allowing you to grasp something and, in this way, move it, rotate it, etc. Pliers are usually hand tools, although there are also machines in which pressure is exerted through electrical energy or hydraulic energy .
For example: “Can I borrow a tweezer? I need to remove a nail from the wall” , “To adjust the pieces, you will need pliers” , “The installer cut the cables with pliers” .
Types of clamps
According to the characteristics of their tips, tweezers have different functionalities. Pressure clamps are those with somewhat flattened ends, which also have a bolt to establish different levels of separation depending on what you want to adjust. Cutting pliers , on the other hand, have sharp tips for cutting things.
Hair removal tweezers , as their name indicates, have been designed to grab a hair between their tips and thus be able to extract it. In this way, it is possible to remove hair from various body regions.
Its use in swimming
Swimmers often use clips to keep their nose closed and prevent water from entering the body through the nostrils. They are simply called nose clips and are also used for canoeing.
Since swimming pool water contains certain chemicals such as chlorine, if it enters the body it can cause irritation. On the other hand, this practical accessory is very useful in the first swimming classes, so that students can focus on technique.
The ends of the legs of certain animals are known as pincers.
Tongs in the kitchen
In the kitchen there is more than one type of tong, such as the salad tong that allows you to serve the salad easily and in generous portions, preventing the pieces of vegetables from falling off along the way.
There is also the nutcracker tongs , known simply as a nutcracker and ideal for breaking the shell of nuts, including walnuts, hazelnuts and chestnuts.
The ammeter
Ammeters are instruments used to measure the intensity of current flowing at a given time through an electrical circuit . The clamp meter is a type of ammeter that serves to prevent opening the circuit in which you want to perform said measurement, something that would otherwise be necessary.
This clamp works based on the indirect measurement of the current that circulates through a conductor based on the magnetic field or fields generated by it. The name of this tool is due to the fact that it has a clamp (in which the sensor is located) that opens and grabs the cable on which you want to make the measurement.
In addition to the convenience of not needing to open the circuit, another advantage of the current clamp is that it avoids voltage drops that can occur with a traditional ammeter. In addition, it offers greater safety to the operator since no electrical contact must be made with the low circuit (even when working with insulated cables, it does not require opening the insulator).
Other uses of the term clamp
In another sense, the ends of the legs of some arthropod animals are known as pincers. Lobsters are an example of an animal that has claws.
A dart, finally, can be a seam that is made on a fabric to fold it in a specific way: “The dressmaker told me that, with a dart at the bottom, the dress will fit perfectly.”
