Description

The high efficiency Portable electric cicular saw

Technical field:

The utility model relates to the used electric saw of construction and decoration field carpenter, particularly high efficiency Portable electric cicular saw.

Background technology:

In the construction and decoration process, portable electric saw is one of main tool of using of carpenter.And present portable electric saw also exists the problem of many inconveniences, the one, when closely operating, need to use the handsaw operation with saw right-hand member workpiece, can't use portable electric saw, the 2nd, when blanking, get and mark line repeatedly, the 3rd, when sawing, easily run line, the 4th, dimension line is easily hidden by sawdust when sawing, be difficult for observing, thereby these problems have increased labor strength, waste time and energy, workman's inconvenient operation, cause the construction quality accident when serious, influence operating efficiency.

The utility model content:

In order to overcome existing Portable electric cicular saw inconvenient operation and to process coarse deficiency, the utility model provides a kind of high efficiency Portable electric cicular saw, and this high efficiency Portable electric cicular saw is when operation, and is not only easy to operate, and has the characteristics of precision machining.

The technical solution of the utility model is: this high efficiency Portable electric cicular saw comprises the fixedly catch of saw blade, base, motor, saw blade, secure shroud and movable shield, base front and back end and saw blade are hinged with the righting wheel that is slightly less than saw blade thickness on an axis, the left side of base is hinged with guiding ruler, slightly contract in the groove on the nearly base in the outer face of saw blade, catch has counterbore outside the hole placed in the middle, can positive and negative motor rotating and secure shroud be separated by and form the wind chamber, before and after have inside and outside the lower end with motor wind chamber mutually the secure shroud of breather pipe link to each other with guard shield by buckle, the jump ring sheet that blocks movable shield is mutually arranged in the guard shield rear end at least.

On the jointed shaft of above-mentioned righting wheel spring is arranged; Connecting ear on the L shaped guiding ruler two ends is fixed in the slotted hole of base front and back end by nut; There is dimension line the front and back end on the slotted hole surface; The adjustable block at two ends links to each other with base by reed in the groove; The left back place of base is fixed with at least one pair of fixedly jump ring sheet; Front and back end slotted hole upper surface has dimension line; Interior 0.5 millimeter of the nearly groove of outer end reduction of area of saw blade.

The beneficial effect that the utlity model has is: this high efficiency Portable electric cicular saw is owing to be hinged with the righting wheel that is slightly less than saw blade thickness on an axis in base front and back end and saw blade, when blanking, roll in the material mouth that electric saw is sawed out by righting wheel, can guarantee that electric saw takes the air line, make that processing is more accurate; The left side of base is hinged with guiding ruler, adjusts guiding ruler by the scale of pressing on the base front and back end, can 13 centimetres with interior narrow dimension timber sawing, sawing is more accurate fast, exempts the operation of line; In the groove owing to slightly contract in the outer face of saw blade on the nearly base, catch has counterbore outside the hole placed in the middle, so just can be when saw right-hand member workpiece be closely operated, can sawing, outside using saw during the guiding ruler blanking, differ from original saw baselap and go out 2.7 centimetres in the saw blade outside, than returning or return 2.7 centimetres of lines in the actual size outward, blanking is more accurate, time saving and energy saving when ruling when having removed blanking from; Can positive and negative motor rotating and secure shroud be separated by and form the wind chamber, have inside and outside the lower end, front and back with motor wind chamber mutually the secure shroud of breather pipe link to each other with guard shield by buckle, so just sawdust can be blown open, be convenient to observe dimension line; The jump ring sheet that blocks movable shield is mutually arranged in the guard shield rear end at least, and movable shield is convenient to fix when making sawing.That thereby this high efficiency Portable electric cicular saw has is time saving and energy saving, alleviated labor strength, and the workman is easy to operate, reduces the work operation, guarantees that processed size is more accurate, has improved the characteristics of operating efficiency.
