Detailed description of the invention
Embodiment: as Figure 1-4, the invention provides the specific embodiment of a kind of rotatable Novel electric tool, it casing 1 including being combined by first and second half casing 10,12 be connected with casing 1 and have the handle 2 of a hinge portion 20, motor 3 in casing 1, can around hinge portion 20 with adjust handle angle first and second semifixed portion 40,42 and be arranged on and rotate freely positioner between casing 1 and first and second semifixed portion 40,42。Wherein electric tool is preferably grass-mowing machine, it can also be the electric tool with handle such as GREEB HEDGE MACHINE or chain saw, first and second semifixed portion 40,42 is the two elements of separate type in the present embodiment, the discrete component that can also be one-body molded and have at least part surface to be circular arc, convenient rotation, can realize the object of the invention too。
This rotates freely, and positioner includes being arranged on the fixing groove 120 in the second half casing 12, one end is snapped in the positioning piece 5 in fixing groove 120, provides the spring 6 that keeper 5 opens or shrinks, the cannelure 420 being arranged in first and second semifixed portion 40,42。At least provided with cambered inwards a pair locating recesses 422 in its intermediate annular groove 420, this locating recesses 422 be 180 degree spaced apart, with the anglec of rotation of limit chassis 1 in 180 degree, the number of certain locating recesses 422 can also be more than three or four。
Keeper 5 be three around and the integrated injection molding part of elastically deformable, it includes base portion 50, be positioned at outside base portion 50 and be buckled in the holding part 51 of fixing groove 120, a pair elastic support arm 54 being extended from the two ends of base portion 50, protruded to center from elastic support arm 54 and with the location division 56 of locating recesses 422 location fit and being protruded to center from base portion 50 and with cannelure 420 against the arc protuberance 58 coordinated。Wherein between two elastic support arms 54, interval is formed with a breach 52, with guarantee two elastic support arms 54 have enough elasticity come close to each other or away from。It is understood that locating recesses 422 can also make salient point into, location division then changes depression accordingly into。
The two ends of spring 6 are fixed on the free end of elastic support arm 54, form an enclosed assembly through breach 52 and with keeper 5, to be set in the outside in first and second semifixed portion 40,42, and guarantee the reciprocating motion of elastic support arm 54。
This operation principle rotating freely positioner is as follows: time initial as shown in Figure 2, holding part 51 is buckled at fixing groove 120, the location division 56 of two elastic support arms 54 is housed in locating recesses 422, spring 6 two ends are fixed on the free end of elastic support arm 54 and are in contraction state simultaneously, this spring 6 is adjacent with the first semifixed portion 40, when identifying direction of rotation during user is according to figure and rotating casing 1, as shown in Figure 3, owing to the holding part 51 of keeper 5 is buckled in the fixing groove 120 of casing 1, the rotation rotarily driving keeper 5 of casing 1, the location division 56 of two elastic support arms 54 departs from the cooperation of locating recesses 422, and it is outwardly into first, two semifixed portions 40, in cannelure 420 on 42, thus spring 6 is in extended state, etc. when rotating to 180 degree, as shown in Figure 4, the location division 56 of two elastic support arms 54 is returned in locating recesses 422 to coordinate, spring 6 is adjacent with the second semifixed portion 42, spring 6 is in again contraction state and limits first simultaneously, 2 half casing 10, the rotation of 12, thus reaching to realize spinfunction when there is no rotary knob。
It is understood that the principle of the head rotating according to above-described embodiment, it is also possible to it is applied to rotatable handle, thus also can realize the rotation of electric tool, it is simple to user adjusts the switching of work surface or function。This electric tool includes: has the handle of several locating recesses/salient points, is set in the main body outside handle and is arranged on and rotates freely positioner between main body and handle, wherein rotates freely positioner and at least include being fixed in main body and being set in the positioning piece coordinated outside handle and with locating recesses/salient point。Wherein locating recesses/salient point be 180 degree spaced apart, with the anglec of rotation of limit chassis 1 in 180 degree, it is also possible to be 90 degree of distributions and the number of locating recesses/salient point is four。
The described positioner that rotates freely also includes being arranged in main body and the fixing groove of fixed positioning piece and the spring that provides keeper to open or shrink。
Described keeper is three integrated injection molding parts surrounded, it includes base portion, be positioned at outside base portion and be buckled in the holding part of fixing groove, a pair elastic support arm extended by the two ends of base portion and by elastic support arm protrude to center/recessed go out and can with the location division of locating recesses/salient point location fit, wherein between two elasticity support arms, interval is formed with a breach。
The two ends of described spring are fixed on the corresponding free end of two elastic support arms, and form an enclosed assembly with keeper。
Compared with prior art, in the present invention, user can directly rotate body certain angle to realize the conversion of work surface or function, and it is convenient and simple and reliable for structure to rotate, and in the outside of body without settings button so that outward appearance smoothness more attractive in appearance。
Certain above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this。All equivalent transformations done according to the spirit of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention。
