See also Fig. 1, Fig. 2, it is respectively the front/rear stereochemical structure exemplary plot of safety device action of a preferred embodiment of the present utility model, and Fig. 3, Fig. 4 then are respectively the front/rear side structure exemplary plot of safety device action of above-mentioned the utility model preferred embodiment.
At first, by among Fig. 1～Fig. 4 as can be known, a machine hammer 10 is made up of a nail hitting body and a safety device.Wherein, this machine hammer comprise at least nail hitting casket 12, that a nail hitting switch 11, has several nail body (not shown)s and be located at the front end of this nail hitting body be located at this nail hitting casket 12 the place ahead, top go out nail mouthful 121, one motor component 13, a rotating member 14, a collision block 15, a fixed component 16, a compression spring 17 and a handle 18., when the user held by this handle 18 and can press by this nail hitting switch 11 smoothly, this nail hitting switch 11 promptly can move to a second switch position S2 from one first position of the switch S1, and this motor component 13 can start and drive this rotating member 14 synchronously and rotates this moment.Certainly, be abutted against mutually with the driving lever 141 of this rotating member 14 and be located at this collision block 15 in this fixed component 16, also can be synchronously along with the rotation of this driving lever 141, and by the projection 151 in the guide rail 161 that is arranged in these fixed component 16 both sides (side only is shown among the figure), and the switch moving direction that indicates M in figure is carried out slip, thereby compresses this compression spring 17 to obtain a compression energy.In case after this collision block 15 broke away from this driving lever 141, this collision block 15 can compress the compression energy that spring 17 is accumulated by this, bump is positioned at this nail body (not shown) that goes out nail mouth 121, so that it hits and hammers in the object (for example, be a plank etc., but not shown).
Preferable way as for relevant the utility model institute lifting safety device then sees also above-mentioned Fig. 1～solid and side exemplary plot shown in Figure 4, and cooperates and consult Fig. 5, the front/rear polycrystalline substance exemplary plot of safety device shown in Figure 6 action., this safety device comprises: push rod 20, the ring rotation element 22, with lug boss 201 has the return mechanism that hole seat 23 constituted of annular accommodation space 231 and projection 232 and uses a pivoting member 241 and be arranged at the ㄇ type driving lever 24 of this nail hitting body.Wherein, this ring rotation element 22 includes convex annular axle 221, peristome 222, ring part 223 and support surface 224 at least.In addition, the torque spring that this return mechanism comprised (please consulting the Reference numeral 25 among Fig. 7, Fig. 8 earlier), then be in order to being sheathed on this convex annular axle 221, and this is arranged with this convex annular axle 221 of this torque spring 25, wears and place this annular accommodation space 231.
Wherein, this push rod 20 is adjacent to the top of this nail hitting casket 12 and this fixed component 16 and slightly protrudes in this and goes out nail mouth 121, for replacing action with the surface of this object.In addition, by being located at, the rear end of this push rod 20 then is arranged with a spiral spring 21, when not being resisted against this object with the front end in this push rod 20, can make this push rod 20 get back to original position with a rod end 242 of this ㄇ type driving lever 24 for 201 of this lug bosses.Certainly, this fixed component 16 has two L type extensions 162 that are oppositely arranged, and can move in order to this lug boss 201 is bound between this rod end 242 and this L type extension 162.
Further and opinion, the concrete operating principle of relevant the utility model embodiment is described as follows at this:
See also Fig. 1, Fig. 3 and Fig. 5, and please cooperate the part of the stereochemical structure before the safety device action shown in Figure 7 to amplify exemplary plot.When this push rod 20 was not replaced this object, this spiral spring 21 can make this push rod 20 keep slightly protruding in the original position that this goes out nail mouthfuls 121, and made this lug boss 201 and this rod end 242 mutually by being located at together.On the other hand, this ring rotation element 22 is owing to be sheathed on the twisting force of this torque spring 25 of this convex annular axle 221, can make another rod end 243 of this ㄇ type driving lever 24 mutual to establishing with the extension 2221 of this peristome 222, and protrude in this projection 232 of the lower surface of this hole seat 23, can replace mutually with these ring part 223 outward extending fixture blocks 2231.Certainly, also can replace (that is, be resisted against shown in Figure 5 one first mutually and replace position L1) with the lug boss 112 of stretch flange formability 111 in this nail hitting switch 11 mutually because of this support surface 224, therefore, this nail hitting switch 11 promptly can be positioned in this first position of the switch S1.Although user's desire this moment is pressed by this nail hitting switch 11, also can't move this nail hitting switch 11.Therefore, this structural design can prevent that obviously user's mistake is by this nail hitting switch 11.
On the other hand, see also Fig. 2, Fig. 4 and Fig. 6 again, and please cooperate the part of the stereochemical structure after the safety device action shown in Figure 8 to amplify exemplary plot.Promptly, when this push rod 20 is replaced this object, this lug boss 201 can be stirred this rod end 242, and related this another rod end 243 that makes also can be stirred and its this extension 2221 by establishing mutually synchronously, and this support surface 224 is no longer replaced mutually and this first is replaced position L1 and move to one second and replace position L2 (as shown in Figure 6) certainly with this lug boss 112, at this moment, this peristome 222 of this ring rotation element 22 is promptly corresponding mutually with this lug boss 112.That is to say, if user's desire is carried out the action of pressing by this nail hitting switch 11 this moment, can allow this lug boss 112 enter this peristome 221 smoothly, thereby this nail hitting switch 11 can be moved, to this second switch position S2 from this S1 place, first position of the switch to enter the percussion state that starts this nail hitting switch 11.
At last, withdraw from this peristome 221 and make this nail hitting switch 11 return to this first position of the switch S1 in this lug boss 112 from this second switch position S2, and when this push rod 20 is no longer replaced this object, this spiral spring 21 also can make this push rod 20 keep slightly protruding in the original position that this goes out nail mouth 121 once again, and this support surface 224 also can be resisted against this once again mutually with this lug boss 112 and first replaces position L1, prevents the safe condition of user's mistake by this nail hitting switch 11 thereby be returned to.
In above-mentioned The Creation Conception, similar remodeling of equal value of other of relevant this return mechanism or design, comprise and to change into, and utilize manual type that this ring rotation element 22 second is replaced position L2 and directly dialled and get back to this and first replace position L1 from this with a dialing part (not shown).
In sum, the utility model utilizes the safety device of above-mentioned novelty and tool reliability, can reach really to prevent the phenomenon of user's mistake by this nail hitting switch.
The utility model is by the various remodeling that those skilled in the art did, the scope of neither disengaging claims institute desire protection.
