The gripper is a common and practical tool, frequently employed in operations like gripping, stretching, and seizing. It comes in a plethora of shapes, with the commonly seen ones being pincer - shaped, triangular, spiral, and so on. Thanks to its uncomplicated structure and portability, the gripper enjoys extensive applications in daily life. People also refer to it as a multi - purpose gripper. Moreover, it is an essential and indispensable tool in industries such as machining and auto repair.

There are various types of grippers, such as pincer - shaped grippers, triangular grippers, and spiral grippers. The pincer - shaped gripper can pick up extremely small objects. It can be used to grasp tiny items on clothes or to remove machine screws. It has a relatively strong gripping force and is often used to grab larger objects, like cylindrical ones. The spiral gripper, on the other hand, has an excellent ability to grip curved surfaces, for example, it can hold pipes.

The gripper is a practical tool, and proper usage methods are required to ensure safety and its long - term usability. Firstly, check whether the structure of the gripper is intact to avoid damage, thus preventing potential safety hazards during use. Secondly, operate the gripper correctly. Under no circumstances should it be used to grip high - temperature objects, as this may cause the gripper to deform or get damaged. Since its service life may be relatively short, regularly inspect the surface and the jaws of the gripper so that worn - out grippers can be replaced in a timely manner.

As the gripper is frequently used, it will be subject to wear and tear, and thus requires regular maintenance. Firstly, clean the dirt on the surface of the gripper. Secondly, lubricate the gripper promptly to ensure its normal operation. Also, conduct regular inspections to prevent damage.

The origin of the gripper can be traced back to ancient times. It is an ancient yet practical tool. As early as the 19th century BC, the ancient Egyptians had already manufactured grippers using cast iron. By the end of the 19th century, due to the development of science and technology, the material of the gripper evolved from cast iron to steel, making its performance more stable and reliable. Even today, the gripper remains an essential part of practical tools and is deeply loved by people.

The selection of the gripper is also of great significance. One should choose a suitable gripper according to actual needs. Firstly, based on the on - site operating environment, select a gripper that is more stable and durable. Secondly, according to the shape of the object, choose a more appropriate gripper. For example, a triangular gripper can be used to grasp cylindrical objects. Additionally, considering one's own technical capabilities, choose a gripper that is suitable for one's own operation to ensure work efficiency.

In conclusion, the gripper, as a practical tool, has a wide range of applications in daily life. It can not only be used to grip objects but also to achieve many other functions. For instance, when placing paper on a table, the gripper can be used to hold the paper, preventing it from being blown away by the wind.

All in all, the gripper is a practical tool with diverse shapes. One should select a suitable gripper according to actual requirements, pay attention to its usage precautions, and carry out regular maintenance to ensure its long - term and reliable operation.
