Specific embodiment
Present embodiment discloses a kind of chain saw guide plate, including the first guide plate 1 for be arrangeding in parallel and the second guide plate 2 and connection
Middle guide plate 3 between the guide plate 2 of first guide plate 1 and second, here the first guide plate 1, the second guide plate 2 and middle guide plate
It is bolted integral, naturally it is also possible to use clamping or bonding；The periphery of middle guide plate 3 is recessed in first guide plate
1 with the periphery of second guide plate 2 and form a guide groove 4, the guide groove 4 be used for place saw chain, to saw chain play guiding and limit
Effect；Roller bearing 5, the roller bearing 5 are installed near front end between first guide plate 1 and second guide plate 2
On sprocket wheel 6 is installed, be provided with nine within one week in the corresponding part of the gear teeth of the sprocket wheel 6 on the guide plate 2 of first guide plate 1 and second
Insertion and size identical suction hole 7, according to actual convenience, the number of the suction hole 7 can also be six, seven, eight
It is individual etc., it is also possible to be only opened on the first guide plate 1 or the second guide plate 2, the shape of the suction hole 7 can be it is circular, square,
Triangle etc., the suction hole 7 on the guide plate 2 of suction hole 7 and second on the first guide plate 1 can also stagger certain angle, justify here
The diameter of shape suction hole 7 should be high less than or equal to sprocket.The setting facilitates sprocket wheel to rotarily drive air-flow at a high speed, using gas
