Preferably, in technique scheme, the center on the top of latch is provided with breach, and the both sides of breach form stay.
Preferably, in technique scheme, the center of base is provided with positive stop lug boss, and the latch of taper is arranged on positive stop lug boss, and positive stop lug boss is arranged in the centre hole of gear.
Preferably, in technique scheme, the center of the lower surface of base is provided with for holding the spacing hole at the top of latch.
Preferably, in technique scheme, the top of stay is hook-shaped.
Compared with prior art, the utlity model has following beneficial effect:
Protective device of the present utility model can all be placed on gear in the inner chamber of protective device, anti-collision and dustproof, and fixed gear wheel more stably, prevent gear separation protective device unintentionally, safety is higher, avoids doing over again, reduce reject rate, improved production efficiency, reduced cost; This protective device structure is simple, easily makes, and cost is low, and method of operation is simple.
