What are the connection methods of the sleeve?

Socket is the abbreviation of socket wrench. What are the connection methods of general sockets?

There are four types of commonly used connecting sleeves: standard sleeves, positive and negative screw-type sleeves, variable diameter sleeves, and adjustable sleeves.

Standard sleeves are mainly used for the connection of rotatable steel bars of the same diameter;

Positive and negative screw sockets are used for the connection of steel bars where the steel bars at both ends cannot be rotated but at least one steel bar can move axially, such as the construction of turning iron steel bars;

The reducing sleeve is used for the connection of steel bars of different diameters;

The adjustable sleeve is used for the connection of steel bars that cannot be rotated at both ends, and can also be used for the connection of steel bars at the turning iron.

When the axial position of the steel bars at both ends cannot be moved, this type of pull head can only be used, such as the butt joint of steel bars in the connection construction of two prefabricated large concrete structures.
