expansion fork的意思|示意

Expansion fork is a type of tool used in woodworking or metalworking. It is a type of pronged fork used to expand or separate two pieces of wood or metal.

Expansion fork is usually made up of three or four prongs with an adjustable handle. The prongs are designed to slide into the two pieces of material at the same time, creating a larger gap between them. The handle is used to adjust the size of the gap, depending on the size of the material that needs to be expanded.

The most common use of the expansion fork is to join two pieces of wood or metal together. The user inserts the prongs into the wood or metal, then turns the handle clockwise to expand the gap. This creates a tight bond between the two pieces. Expansion fork can also be used to separate two pieces of material that have been joined in the past. This is done by turning the handle counterclockwise, which will decrease the size of the gap between the two pieces.

Expansion fork is a great tool for any woodworker or metalworker. It is a very useful and versatile tool that can be used for a variety of applications.
