Aforementioned is the technical characteristics of the main embodiment of the utility model.
After the complete technical characteristics of the present utility model of above-mentioned explanation, existing in lower further feature of further describing each parts of the present utility model in detail:
One, refer to Fig. 2, Fig. 3, shown in Fig. 5, can rely on for the convenience of the users finger to switch the rotating speed of adjusting pneumatic tool 10, therefore at this, allot dish 42 outer circumferential sides and be further equipped with a tooth row 422, and the groove direction of this tooth row 422 is from pressing press button 5 toward switch piece 41 horizontally sets, and by the utility model set position on pneumatic tool 10, user is utilized one hand can complete switching adjustment, with the time in saving work, without must switching and adjust air tool rotating speed by the cooperation of both hands in picture prior art, it is worth mentioning that in addition, this embedding support 4211 of alloting the group hole 421 offered, dish 42 centers with control to the assembly of 31, the clamping platform of axle 3, by this embedding support 4211 and clamping platform 31, to be all the straight angle design of 180 degree, when alloting dish 42, be inserted in control while establishing to axle 3, this embedding support 4211 can corresponding clamping platform 31 gives group and establishes and fasten, therefore when stirring, user allots while coiling 42, by embedding support 4211 and clamping platform 31, mutually fasten the rotating speed that is really switched pneumatic tool 10.
They are two years old, in the design of pneumatic tool 10, except providing user to adjust rotating speed, also have and change turning to of pneumatic tool 10, and can reach change pneumatic tool 10 at switch piece 41 of the present utility model, turn to, and in order to provide user really to switch, therefore the outer circumferential side of switch piece 41 further protruded out all 411, this is cut and 411, is long column shape and stretches out, user is when controlling pneumatic tool 10 running, as need flip-flop its while turning to, only need to pull and press cutting of switch piece 41 411 actions of controlling control valve group 1 can be changed to turning to of pneumatic tool 10, refer to Fig. 2, Fig. 3, shown in Fig. 5, (the utility model only illustrates that cutting of switch piece 41 changes turning to of pneumatic tool 10 411 design person easy to use, not in order to limit its external form, turning to of switch piece 41 control pneumatic tools 10 is prior art again, in this its control mode, do not repeated).
They are three years old, refer to shown in Fig. 3, no matter in order to allow user allot dish and 42 change turning to of pneumatic tool 10 pressing switch piece 41 or stir, during rotating speed, each assembly can not influence each other to each other, one side of therefore alloting dish 42 and corresponding control valve group 1 in these switch piece 41 correspondences respectively offers a groove chamber 412, separately in each groove chamber 412, be provided with an elastic component 6 and a positioning bead 7, each positioning bead 7 is installed in the notch of corresponding groove chamber 412, each elastic component 6 is installed in respectively each butted positioning bead 7 in 412Nei Qie one end, groove chamber, the other end is butted in 412 bottom surfaces, groove chamber, each positioning bead 7 is alloted dish 42 and control valve group 1 by the butted pushing and pressing respectively of each elastic component 6, so make to allot dish 42, 1 of switch piece 41 and control valve group have spacing setting, make can reciprocal effect not arrive the process of switching between three.
They are four years old, used for a long time by user, be exactly nothing but for start pneumatic tool 10 running by press button 5, by pressing by press button 5, make pneumatic tool 10 be come into operation or stop, it is indispensable assembly, its installing mode is by the setting of main spindle 2, this main spindle 2 runs through control to axle 3, one end of its corresponding pneumatic tool 10 inside is connected mutually with inside, the other end protrudes from one end that control exposes to axle 3, and with press press button 5 phase mutual connections, it is worth mentioning that, separately be provided with an axle center 8 by running through by press button 5 by the side of press button 5, and further run through main spindle 2, to fix by the group of 2 of press button 5 and main spindles, connect whereby, prevent from when action, departing from the assembling with main spindle 2 by press button 5, refer to Fig. 2, shown in Fig. 4.
According to above-mentioned every explanation, the utility model is via the embedding support 4211 of alloting 42 groups of holes 421 of dish, and control is to the assembly setting between the clamping platform 31 of axle 3, so that being provided, user can really switch the rotating speed that changes pneumatic tool 10, and can be as prior art, because utilizing the lock of fixture (screw), establish, cause the tooth that collapses between switch bar and fixture to wear away, and then cause switch bar cannot really control air tool transformation of speed, in addition, after fixture (screw) and switch bar abrasion, fixture can get loose and depart from the assembling with switch bar, and then cause the autorotation of switch bar and misplace, cause user cannot really adjust to correct actuating speed, can waste thus outside the time of work, the shortcoming that even easily jeopardizes user's safety and destroy thing to be bored, therefore, by the utility model, alloting dish 42 embedding support 4211, to coordinate control to provide society to have to the assembly design of the clamping platform 31 of axle 3 more convenient, operation more easily.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
