The newel lower end is provided with the fixing spring of radial position, the upper-end surface of clamping device is installed with location piece, newel lower end and clamping device upper-end surface are rotatably connected by screw rod and nut, location piece is provided with the circular positioning hole that is arranged in the location piece edge, is provided with steel ball between spring and positioning hole.

The newel upper end has U-groove bevel, the bottom of stem is embedded in the U-groove bevel, and be rotatably connected by screw rod and nut, be installed with spring and location piece between the surface of contact of stem bottom and U-groove bevel respectively, location piece is provided with into the positioning hole of circular-arc arrangement, is provided with steel ball between spring and the positioning hole

Described base is a C shape, and depression is positioned at the middle part of C shape.

Described base is an E shape, and depression is positioned at the middle part of E shape.

Clamping device is inboard to be provided with the folder pad with the base contacted position of caving in.

Back cover is provided with some square grooves.

Net and back net before described catch net comprises, preceding net and back Netcom cross the some of its edge the buckle engaging are fixed together.

Described back net ear end face is provided with the U-shaped groove.

The utility model is equivalent to a folder fan when not comprising base, can be clamped in the arbitrary position fixes, form arbitrarily angled, be equivalent to desk fan when comprising base, be equivalent to wall fan again when being fixed in its fixed hole on the metope, so the utility model has the advantage of folder fan, desk fan and wall fan simultaneously concurrently by the clamping device bottom surface.
