On the ratchet of wheel.
Described toothholder one end is provided with some positioning ribs, and the pivoted hole of linking arm is provided with the locator card of corresponding matching therewith
Groove, toothholder is fixed on pivoted hole by the cooperation of positioning rib and locating groove.
The fan head and the linking arm of support two articulated section of one of them set limit to turn spacer, the fan head
Drive-connecting shaft passes through the pivoted hole of corresponding linking arm to turn spacer with limit and is fixedly connected.
Described to limit sidepiece one projection of extension for turning spacer, the linking arm is provided with the chuck coordinated with projection, fan machine
Head drives the limit to turn spacer and turns to projection with limiting the scope of fan head rotation during chuck contact when rotating.
The limit turns spacer and is provided with dust cover.
The positioning component is provided with dust cover.
Using said structure, determined because the articulated section of the utility model fan head and linking arm is set by toothholder and rotation
Bit slice matches somebody with somebody the rotational positioning component being combined into, and instead of sheet rubber of the prior art, overcomes rubber present in prior art
Film is easy to wear, the technical problem of aging.
