Abstract
The utility model discloses a working head of angle mill, including button device on head shell, the head shell, adorn output shaft on the head shell, drive the gear of output shaft, adorn in the epaxial grinding wheel of output, fix the wheel guard on the head shell, its characterized in that: the button device comprises a button, a compression spring is arranged between the button and the head shell, one end of the stop pin is fixed on the button through a through hole on the head shell, and the other end of the stop pin is blocked by the head shell; the gear is provided with at least two stop holes along the circumferential direction. The utility model is simple in operation, dismouting grinding wheel is convenient.
Description
Technical field
The utility model relates to field of power tools, the working head of especially a kind of angle grinding machine.
Background technology
Because the grinding wheel of angle grinding machine is easy to wear, need often to change grinding wheel, change grinding wheel usually and need two spanners, one blocking output shaft, and one the slewing circle nut, also needs fixed main body simultaneously, and both inconvenient, efficient is also very low.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple, convenient working head of dismantling the angle grinding machine of grinding wheel efficiently is provided.
The utility model is achieved through the following technical solutions: the working head of a kind of angle grinding machine, comprise PBU pushbutton unit on head capsule, the head capsule, be loaded on output shaft on the head capsule, drive output shaft gear, be loaded on grinding wheel on the output shaft, be fixed on the wheel guard on the head capsule, it is characterized in that: described PBU pushbutton unit comprises a button, the compression spring is housed between button and the head capsule, latch one end is fixed on the button by the through hole on the head capsule, and the latch other end is then blocked by head capsule; Along the circumferential direction be provided with at least two position-arresting holes on the described gear.
Position-arresting hole on described latch and the gear is on the same circumference.
The beneficial effects of the utility model are: owing to adopt said structure, when pressing the button, latch enters in the gear position-arresting hole, and gear and output shaft can not rotate, and with one spanner degree of tightness round nut, quickly grinding wheel is unloaded or loads onto with regard to the energy instant noodles.After loading onto grinding wheel, release button, the compression spring is upspring button, and drive latch and move, out-of-gear, gear and output shaft are free to rotate.

The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings:
Referring to Fig. 1, Fig. 2, the working head of a kind of angle of the utility model grinding machine comprises head capsule 1, PBU pushbutton unit 2 on the head capsule 1, be loaded on the output shaft 3 on the head capsule 1, drive the gear 4 of output shaft 3, be loaded on the grinding wheel 6 on the output shaft 3, be fixed in the wheel guard 5 on the head capsule 1, described PBU pushbutton unit 2 comprises a button 21, and compression spring 22 is housed between button 21 and head capsule 1 pit, and latch 25 1 ends are fixed on the button 21 by the through hole on the head capsule 1, latch 25 other ends are then blocked by head capsule 1, and circumferential several position-arresting holes 41 are arranged on the described gear wheel 4.
During the utility model work, press the button 21, overcome the elastic force of compression spring 22, button 21 embeds leaves recess 24 on head capsule 1, and latch 25 moves downward under button 21 drives, and latch 25 is entered in the position-arresting hole 41 of gear 4, and gear 4 can not rotate.Because gear 4 is fixed on the output shaft 3, also make the grinding wheel 6 of interlock output shaft 3 not rotate, the round nut 42 that compresses grinding wheel 6 with the spanner handle eases out or screws on then, and grinding wheel is unloaded or loads onto.After finishing the grinding wheel mounting or dismounting, release button 21, compression spring 22 resets, and latch 25 breaks away from gear 4, and gear and output shaft are free to rotate.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but all technical solutions of the utility model contents that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
