State concrete meaning of the term in the invention.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
As shown in Figures 1 to 4, a kind of chain saw locking mechanism, including chain saw helical disk component, the gear being arranged in same axle center
Bits plate 8, chain saw rotary disk assembly, guide plate 2 and chain 18, the chain saw rotary disk assembly are fixed on shred holding up plate 8；The guide plate
Chain 18 is housed on 2；It is characterized by: the chain saw helical disk component is fixed on the bar shaped sliding slot of guide plate 2, and pass through first
Connector 1 and guide plate 2 are fixed；The chain saw helical disk component includes chain saw bushing 3, chain saw sliding block 4 and chain saw helical disk 5；Institute
The pillar 41 on chain saw sliding block 4 is stated, is stuck in the spiral groove 52 of chain saw helical disk 5, and the ellipse sliding slot in chain saw sliding block 4
42 are slidably matched with the chain saw bushing 3 being fixed on casing；The chain saw bushing 3 passes through the ellipse sliding slot in chain saw sliding block 4
42 are inserted into chain saw helical disk 5, and in 3 insertion end shell tool 6 of chain saw bushing, are covered with axis flat wire retaining ring 17.
The chain saw rotary disk assembly includes chain saw knob inserts 10, chain saw locking knob 11 and chain saw rotating disk 12；Institute
It states chain saw rotating disk 12 to be rotatably connected on shred holding up plate 8, and the annular pillar 121 in chain saw rotating disk 12 and chain saw helical disk 5
51 phase of annular groove occlusion；It is provided with elastic slice component on the shred holding up plate 8, and is located at the upside of chain saw helical disk component；Institute
State the top that elastic slice component is fixed on 8 outside of shred holding up plate by the second connector 16.
Wherein, it is provided with torsion directional beacon 19 on the shred holding up plate 8, is locking direction along time orientation, counterclockwise
To loosen direction.
Wherein, first connector 1 uses crossed pan head machine tooth screw, and second connector 16 uses cross slotted disk
Head tapping screw.
Wherein, the chain saw knob inserts 10 is fixed on chain saw locking knob 11, and chain saw locking knob 11 is rotatablely connected
In chain saw rotating disk 12, and chain saw locking knob 11 is rotated centered on chain saw rotation inserts 10 in locking.
The chain saw helical disk component is fixed on guide plate 2, and is assembled on the M8 screw of casing, will finally be covered and be considered to be worth doing in gear
Chain saw rotary disk assembly on plate 8 screws in the locking of M8 screw.The elastic axle center by changing chain saw helical disk component of chain,
Position on guide plate sliding slot is adjusted.When rotating chain saw rotating disk, the chain saw helical disk being mutually engaged with chain saw rotating disk is by band
Dynamic rotation.And the spiral groove on chain saw helical disk is matched with the convex block on chain saw sliding block, and when the rotation of chain saw helical disk, chain
Saw sliding block is driven and generates and move horizontally.Due to having chain saw bushing in the ellipse sliding slot on chain saw sliding block, and chain saw is applied
Screw is fixed on casing, so chain saw sliding block can only move horizontally, is close to chain saw sliding block upper guide plate together to drive
It is mobile.When guide plate is far from axle center, chain is tensioned, conversely, chain unclamps.
Wherein, the elastic slice component includes elastic slice 13, chain saw torsional spring 14 and small briquetting 15；The elastic slice 13 and chain saw torsional spring
14 cover together on the stud of shred holding up plate 8, and elastic slice 13 and chain saw torsional spring 14 are fixed on shred holding up plate 8 by small briquetting 15；
Described 14 one end of chain saw torsional spring passes through elastic slice 13, and the other end is stuck on shred holding up plate 8.The end of the elastic slice 13 passes through torsional spring 14
The gear of torsion and the chain saw helical disk 5 mutually resists, the turning anticlockwise of chain saw helical disk 5 when chain saw being hindered to shake.Elastic slice
When structure can prevent machine operation, because chain saw rotating disk generates rebound caused by vibration, prevent from loosening.
In conclusion the invention locking chain and when guide plate, is tightened without dismantling chain saw, do not need yet using
Other tools drive chain saw helical disk by chain tension, then up time by first rotating clockwise the chain saw rotating disk on chain saw
Needle rotation chain saw locking knob is locked, easy to operate.In the case where locking mode simplicity, elastic piece structure can also be prevented
Because vibration chain saw rotating disk generates rebound and loosens when only chain saw works, without frequently being tightened to chain saw.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope.
