HK4

HK4 is a type of accessory that is used to measure tiny and short-distance distances. It is also used to measure dynamic angles, such as angles in moving parts. HK4 is composed of four parts including a base, two leveling or measuring screws, a pointer, and an arm. These four components make up the entire assembly that can be used to measure small and dynamic spaces and angles.

The base consists of two flat metal plates that have an upper and a lower face. The metal plates are designed to hold the two leveling or measuring screws firmly in place. These two screws are used to fasten the base to a surface so that it is stable during measurement. The leveling or measuring screws are held in place by a locking mechanism that prevents them from rotating.

The pointer is a long, thin piece of metal that is connected to the base by an arm. The arm is a curved piece of metal that is also connected to the base. The pointer and the arm are positioned such that the pointer can be moved or rotated around the curved arm. This is used to measure the angle between the two leveling or measuring screws.

The working principle of HK4 is quite simple and is based on how a hand held protractor works. To measure an angle, the pointer is rotated to a given position. This position is determined by the reading of the two leveling or measuring screws. When the pointer is set to the right angle, it will indicate the same angle relative to the base. This process can be repeated for various angles in order to measure the length of a line, the size of an angle, or even the distance between two points.

HK4 is a useful accessory for people who need to measure short distances and dynamic angles. It is also useful for mechanical measurements, such as measuring the angles in assembly lines. HK4 has become popular due to its accuracy and ease of use.
