Further, the pressing handle is arranged at the middle part of the second locking part.
Further, a connecting hole is formed in the lower end portion of the second locking portion and is used for being rotatably connected with the chain saw upper cover body, and the chain saw upper cover body is connected with a corresponding connecting hole or pin seat on the chain saw upper cover body.
Further, an anti-slip strip is arranged on the second locking part.
Preferably, the locking device is a nylon plastic piece, has larger toughness and tensile strength, ensures that the locking device cannot break under severe vibration, and cannot deform after frequent pulling out and pressing due to small stress.
The using method comprises the following steps: the first locking part and the pressing handle are outwards broken by hands, so that the first locking part and the pressing handle are separated from the clamping groove, and the lock device of the chain saw air filter cover can be opened; the clamping block is pressed downwards by hands to move downwards, and when the clamping block reaches the clamping groove position on the air filter cover, the clamping block is pressed downwards forcefully to be embedded with the clamping groove, so that the air filter cover of the chain saw can be locked.
The utility model has the following beneficial effects: the utility model can realize direct locking or unlocking without the need of disassembling other tools, and the lock device of the oil saw air filter cover can not deform or even lose efficacy after repeated use.
