Detailed description of the invention

By reference to the accompanying drawings, the utility model is described in further detail.

A kind of cutting machine, is characterized in that: cutting machine 30 comprises pedestal 32, pivotal arm 34, saw blade 36, motor 38, door handle device 40 and a starting switch; The rear end 41 of pivotal arm 34 is articulated in the rear end 43 of pedestal 32, and pivotal arm 34 leading section is formed with a guard shield 42; Saw blade 36 penetrates in guard shield 42, has a left surface and a right flank; Motor 38 is installed on pivotal arm 34; Door handle device 40 has carrying handle 44 and an operating handle 46.Carrying handle 44 is U-shaped, and all affixed pivotal arm 34 of its leading section and rearward end, makes carrying handle 44 stand on pivotal arm 34, be positioned at directly over saw blade 36, and and forms an accommodation space 48 between pivotal arm 34.Operating handle 46 is U-shaped, thereafter the leading section of end 49 pivot joint carrying handle 44, is located in above guard shield 42, and its leading section 50 is not fixed in guard shield 42.The inner side of operating handle 46 forms an accommodation space 2 52, installs a starting switch 54 in the inner side of operating handle 46.Cutting machine 30 more comprises a positioner 60, positioner 60 has rod member 62 and an actuator 64, rod member 62 has head 66 and a body portion 68 of extending from head 66, body portion 68 is the pivotal axis of the rearward end 49 of operating handle 46, be positioned at directly over saw blade 36, and running through the rearward end 49 of operating handle 46 and the composition surface 70 of the leading section of carrying handle 44, head 66 is arranged in the rearward end 49 of operating handle 46, and its area of section is greater than the area of section in body portion 68.Actuator 64 has a plate handle 72, a connection piece 74, cam gear 76 and an axostylus axostyle 78, one end fixation plate handle 72 of connector 74, the affixed cam gear 76 of its other end.Axostylus axostyle 78 connects an end in cam gear 76 and body portion 68, and the mode that axostylus axostyle 78 connects the end in cam gear 76 and body portion 68 has at least one to be engage rotationally, axostylus axostyle 78 and be the turning cylinder of cam gear 76.Operating handle 46 is dentation snap-in structure with the connected structure of carrying handle 44, the end face of the rearward end 49 of operating handle 46 provides an arrangement the first teeth portion 80 in the form of a ring, first teeth portion 80 has plural protuberance 82 and the plural recess 84 with protuberance 82 complementation, each recess 84 is between two protuberances 82, and the end face of the leading section of carrying handle 44 provides one and first second teeth portion 86 of teeth portion 80 complementation.

Concrete structure of the present utility model as described above.Wherein, accommodation space 48 holds carrying handle 44 after penetrating for user hand, so as on carry cutting machine 30; The leading section of the rearward end 49 pivot joint carrying handle 44 of operating handle 46, be located in above guard shield 42, its leading section 50 is not fixed in guard shield 42.Like this, when pivot action handle 46, the leading section 50 of operating handle 46 can be moved to the left or to the right, the leading section 50 of operating handle 46 and the line of rearward end 49 can be moved between at least three positions, be respectively the initial position of a parallel saw blade 36, turn 90 degrees from this initial position towards left-handed and turn 90 degrees (as shown in Figure 2,3) from this initial position towards dextrorotation.

Whether starting switch 54 controls motor 38 to be activated, be installed in the inner side of operating handle 46, allow user in time holding operating handle 46, whether started by press switch 54 can be controlled simultaneously, when user's started by press switch 54, motor 38 will be driven saw blade 36 to rotate by driving, now user can press down saw blade 36, make saw blade 36 cut this workpiece.

Fig. 4 is the schematic diagram of the mechanism of attended operation handle 46 and carrying handle 44 in the present embodiment.Fig. 5 is operating handle in the present embodiment 46 and the schematic diagram of the connected structure of carrying handle 44.Operating handle 46 is dentation snap-in structure with the connected structure of carrying handle 44, the end face of the rearward end 49 of operating handle 46 provides an arrangement the first teeth portion 80 in the form of a ring, first teeth portion 80 has plural protuberance 82 and the plural recess 84 with protuberance 82 complementation, each recess 84 is between two protuberances 82, and the end face of the leading section of carrying handle 44 provides one and first second teeth portion 86 of teeth portion 80 complementation.

By this, when plate handle 72 was pressed down to a locking position (as shown in Figure 4), cam gear 76 will by pivotable, and make one the first side wall 88 ejection carrying handle 44 the wall 90 of leading section, through axostylus axostyle 78, ground, rod member 62 substantially vertical composition surface 70 is by post-tensioning, the head 66 of rod member 62 is caused to press the inwall 92 of the rearward end 49 of operating handle 46, cause the first teeth portion 80 firmly engage with the second teeth portion 86 and compress mutually, now operating handle 46 cannot rotate relative to carrying handle 44, when plate handle 72 is pulled from locking position, the first side wall 88 of cam gear 76 will rotate counterclockwise, depart from the wall 90 of carrying handle 44, now, second sidewall 94 of cam gear 76 is by the wall 90 near carrying handle 44, because the distance system of the second sidewall 94 at a distance of the center of cam gear 76 is less than the distance of the first side wall 88 at a distance of center of rotation, therefore rod member 62 is in releasing orientation, its head 66 no longer presses the inwall 92 of operating handle 46, by this, operating handle 46 can be pulled outwardly and move, first teeth portion 80 is separated with the second teeth portion 86, user and the suitable position of rotatable handle 46 to, lower platen handle 72 to locking position again, the adjustment of complete operation handle 46 and fixed operation.

In the present embodiment, utilize the mode that arrangement the first teeth portion 80 in the form of a ring engages mutually with the second teeth portion 86, more predeterminable operating handle 46 can by the angle of locating, namely the first teeth portion 80 and the protuberance 82 of the second teeth portion 86 and the quantity of recess 84 can be predetermined, and with its ring center for angle summit calculates angle corresponding to each protuberance 82 or recess 84, calculate that the first teeth portion 80 often rotates the anglec of rotation representated by distance of a protuberance 82 and a recess 84 by this, so learning operation handle 46 can by orientation angle.

In sum, in embodiment of the present utility model, carrying handle 44 is erectly fixed on pivotal arm 34, be convenient to user hold and carry cutting machine 30, the leading section of the rearward end 49 pivot joint carrying handle 44 of operating handle 46, its pivot points is positioned at directly over saw blade 36, make operating handle 46 can in this initial position, from this initial position towards left-handed turn 90 degrees and turn 90 degrees from this initial position towards dextrorotation etc. between at least three predeterminated positions rotate, the number of those predeterminated positions decides by pre-setting the first teeth portion 80 and the protuberance 82 of the second teeth portion 86 and the quantity of recess 84, whether the plate handle 72 that therefore user can operate actuator 64 compresses the inwall 92 of operating handle 46 to the head 66 controlling rod member 62, and then whether control the first teeth portion 80 engages with the second teeth portion 86 and compresses mutually, to reach convenient and to adjust operating handle 46 rapidly to the angle being applicable to oneself operating habit, when using left hand, operating handle 46 is positioned at the left side of saw blade 36, when using the right hand, operating handle 46 is positioned at the requirement on the right side of saw blade 36.
