Under conjunction, the left side for being adjusted to saw hood 1 can be pushed to shrink saw hood 3 12, saw blade 16 is facilitated to be carried out according to the size of saw material
Saw hood 1 can be movably connected on frame 1 by the axle sleeve 4 in 2 upper shaft of fixed plate, 3 outside, make to protect by the adjusting used
Cover can be fixed, and when saw blade 16 does not need work, with above-mentioned principle, saw hood 3 12 is pushed to the left and goes to frame 1
Top, cooperation saw hood 1 top of saw blade 16 is protected, then with hand to front and back both direction pull two
Hook ring 15 drives the kelly 18 of two 15 opposite sides of hook ring on two limit plates 14 to extract out from card slot 20, then to subinverse
Hour hands rotate saw hood 29, unclamp hook ring 15, and kelly 18, which is retracted, under the elastic force of circlip 17 brings into limit sliding chutes 19, continue
By saw hood 29 turn to frame 1 bottom and kelly 18 be slidingly attached to top card slot 20 in block, cooperate top guiding
Saw hood 29 is fixed on the bottom of frame 1 and is located at the outside of 16 bottom of saw blade by block 7 and connection guide block 8, can be in saw blade 16
Saw blade 16 is completely protected when not working.
In conclusion this has the circular saw protective cover of packing up function, the case where use when according to work, by saw hood 29
It pushes to the left, drives the guide pad 7 on connection guide block 8 to move up along guide groove 6, two guide pads 7 facilitate saw hood 29 to exist
Can be packed up along guide groove 6 is stable when rotation, while kelly 18 being driven to slide in limit sliding chutes 19, when saw hood 29 to
When a left side turns to the top of frame 1, two circlips 17 carry out elastic force contraction to two limit plates 14 respectively, thus band respectively
Dynamic two kellies 18 are stuck in two card slots 20 of bottom, and saw hood 29 is fixed on the inside of saw hood 1 and is fixed on frame 1
Top, while can be according to the size of material to be sawed and using saw blade 16 the case where, saw hood 3 12 can be pushed up, in sliding slot 13
With being slidably connected under cooperation for 10 top shoe 11 of link block, the left side for being adjusted to saw hood 1 can be pushed to receive saw hood 3 12
Contracting, facilitate saw blade 16 according to the size of saw material carry out using adjusting can will by the axle sleeve 4 in the outside of 2 upper shaft of fixed plate 3
Saw hood 1 is movably connected on frame 1, and protective cover is enable to be fixed, when saw blade 16 does not need work, with above-mentioned original
Saw hood 3 12 is pushed to the left and is gone to the top of frame 1 by reason, and cooperation saw hood 1 protects the top of saw blade 16, then
Two hook rings 15 are pulled to front and back both direction with hand, drive on two limit plates 14 two 15 opposite sides of hook ring
Kelly 18 is extracted out from card slot 20, then rotates counterclockwise saw hood 29 downwards, is unclamped hook ring 15, is blocked under the elastic force of circlip 17
Bar 18, which is retracted, to be brought into limit sliding chutes 19, continues the bottom that saw hood 29 is turned to frame 1 and kelly 18 is slidingly attached to push up
It is blocked in the card slot 20 in portion, cooperates the guide pad 7 at top and connection guide block 8 that saw hood 29 is fixed on the bottom of frame 1 and is located at
Saw blade 16 can completely be protected when saw blade 16 does not work, make saw blade 16 in not work by the outside of 16 bottom of saw blade
As when be avoided that and influenced and damage by external environment, while also protective cover can quickly be packed up when saw blade 16 works, be prevented
Only there is the inconvenient problem that worker dismounts circular saw protective cover, avoids the occurrence of security risk or cause safety accident, effectively mention
The high service efficiency of circular saw, solves the problems, such as that existing circular saw is inconvenient at work and packs up shield.
