Embodiment

Embodiment: shown in Fig. 1-4, the utility model provides a kind of specific embodiment of rotatable Novel electric tool, it comprise the casing 1 that combined by first and second half casing 10,12, be connected with casing 1 and have the handle 2 of a hinge portion 20, the motor 3 in casing 1, can be around hinge portion 20 to adjust first and second semifixed 40 of handle angle, 42 and be arranged on the positioner that rotates freely between casing 1 and first and second semifixed 40,42.Wherein electric tool is preferably mower, also can be the electric tool with handle such as GREEB HEDGE MACHINE or chain saw; First and second semifixed 40,42 is the two elements of separate type in the present embodiment, also can be one-body molded and to have part surface at least be the discrete component of circular arc, with convenient rotation, can realize the utility model purpose equally.

This rotates freely positioner and comprises that the holddown groove 120, the ends that are arranged in the second half casings 12 are snapped in positioning piece 5 in the holddown groove 120, a spring 6 that keeper 5 opens or shrink is provided, is arranged on the cannelure 420 on first and second semifixed 40,42.Wherein be provided with at least cambered inwards a pair of location depression 422 in the cannelure 420, this location depression 422 is that 180 degree are spaced apart, and in 180 degree, cave in 422 number of location also can be four certainly with the anglec of rotation of limit chassis 1.

Keeper 5 be three around and the integrated injection molding spare of elastically deformable, it comprises base portion 50, be positioned at base portion 50 outsides and be buckled in the holding part 51 of holddown groove 120, a pair of elasticity support arm 54 that extended by the two ends of base portion 50, by elasticity support arm 54 protrude to the center and the location division 56 that cooperates with location depression 422 location and by base portion 50 to the center protrusion and with cannelure 420 against the arc protuberance 58 that cooperates.Wherein the interval is formed with a breach 52 between the two elasticity support arms 54, with guarantee two elasticity support arms 54 have enough elasticity come mutually near or away from.Be understandable that location depression 422 also can make salient point into, the location division is the corresponding depression that changes into then.

The two ends of spring 6 are fixed on the corresponding free end of elasticity support arm 54, pass breach 52 and form an enclosed assembly with keeper 5, being set in first and second semifixed 40,42 the outside, and guarantee the reciprocating motion of elasticity support arm 54.

This operation principle that rotates freely positioner is as follows: when initial as shown in Figure 2, holding part 51 is buckled at holddown groove 120, the location division 56 of two elasticity support arms 54 is housed in the location depression 422, simultaneously spring 6 two ends are fixed on the free end of elasticity support arm 54 and are in contraction state, this spring 6 and first semifixed 40 is adjacent, when the user according to figure in during sign direction of rotation rotation casing 1, as shown in Figure 3, because the holding part 51 of keeper 5 is buckled in the holddown groove 120 of casing 1, the rotation that rotarily drives keeper 5 of casing 1, the location division 56 of two elasticity support arms 54 breaks away from the cooperation of location depression 422, and outwards enter into first, two semifixed 40, in the cannelure 420 on 42, spring 6 is in extended state thus, Deng rotating to 180 when spending, as shown in Figure 4, the location division 56 of two elasticity support arms 54 is got back to again in the location depression 422 and is cooperated, spring 6 and second semifixed 42 is adjacent, spring 6 is in again contraction state and limits first simultaneously, 2 half casings 10,12 rotation is not having to realize spinfunction in the situation of rotary knob thereby reach.

Compared with prior art, the user can directly rotate the conversion that the body certain angle is realized working face or function in the utility model, and rotation is convenient and simple and reliable for structure, and need not to arrange button in the outside of body, so that outward appearance smoothness more attractive in appearance.

Certainly above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the Spirit Essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
