Description

Technical Field

[0001] The utility model relates to the technical field of fan blades, in particular to a fan blade fixture for a forest fire fighting fan. Background Art

[0002] In simple terms, a forest fire fighting fan is a fire fighting equipment that can be used to extinguish and prevent forest fires. Usually, a magnetic frame is pressed inside the fan blades to form a rotor. When the rotor is defective, the magnetic frame can be reused. Therefore, a jig is needed to separate the magnetic frame and the fan blades. However, when the jig for pulling out the magnetic frame from the fan blades is used, the edge of the iron shell is easily damaged and deformed due to uneven force when the iron shell is removed, causing the iron shell to be scrapped, which will lead to a waste of resources. For this reason, we provide a fan blade jig for forest fire fighting fans. Utility Model Content
