Description
Technical field
The utility model relates to a kind of hand held electric tool, the rotatable hand held electric tool of particularly a kind of handle.
Background technology
At present; Hand held electric tool such as electric angle grinder, polishing machine etc. are in order to adapt to manipulating of different station, different angles; On the connecting portion of housing and handle, be provided with annular groove; Handle is arranged on the annular groove of housing rotationally, and the handle rotary knob is hinged on the handle through back-moving spring, and through handle rotary knob and cooperating of housing locking rotatable handle.But there is following problem in said structure: the one, after the instrument energized is started working; In manipulating process, press because of carelessness or when touching the handle rotary knob; Handle and housing are in rotatable state; Under the rotator inertia effect, cause housing and handle to rotate damage instrument out of control or workpiece, even hurt sb.'s feelings; The 2nd, owing to workman's operation posture, custom, tool work produce the whipping state, instrument is controlled error or the like a variety of causes; Be held in respectively on handle and the body such as two hands; In rotary handle angular adjustment process, started switch suddenly, instrument is run up suddenly by inactive state, at this time can produce a jerk; Under the situation that does not have enough defences, a hand can grip incessantly body; Cause out of control the hurting sb.'s feelings of housing and handle rotation, have serious potential safety hazard.For this reason, many manufacturers and knowledgeable people develop and study to the problems referred to above, but do not have comparatively desirable product to emerge so far as yet.
Summary of the invention
For overcoming the problems referred to above that the rotatable hand held electric tool of existing handle exists, the purpose of the utility model provides a kind of simple and reasonable, easy to operate, safe and reliable hand held electric tool handle rotation interlock.
The utility model solves this technical problem the technical scheme that is adopted; Its hand held electric tool handle rotation interlock comprises housing, handle, handle rotary knob, starting switch, and the connecting portion of housing is provided with annular groove; Handle is arranged on the annular groove of housing rotationally; The handle rotary knob is hinged on handle through back-moving spring, and the interior circle of said housing connecting portion is provided with at least three stopper slots, and middle stopper slot is in directly over the housing connecting portion; The latch part and the stopper slot of handle rotary knob one end are complementary, and the spacing head of the handle rotary knob other end matches with the button of starting switch.
The connecting portion of said housing is provided with protruding block, and handle is provided with and the corresponding locating piece of block.
After adopting said structure, following advantage is arranged compared with prior art: the one, to work as handle and be in rotation status, the spacing crown of handle rotary knob can't press starting switch on the button of starting switch, can prevent that electric tool from starting suddenly; The 2nd, in running order when electric tool, the sidewall of starting switch withstands on the spacing head of interlock switch, and the latch part of interlock switch is buckled in the stopper slot of housing all the time, and handle can't be rotated.Two-way interlocking through the handle rotary knob guarantees can be not out of control between handle and the body, thereby start suddenly when having eliminated rotation or rotation is suddenly brought during work potential safety hazard.

The specific embodiment
Fig. 1 is to shown in Figure 5; Specific embodiments for a kind of hand held electric tool handle rotation of the utility model interlock; It comprises housing 1, handle 8, handle rotary knob 5, starting switch 7, and the connecting portion of housing 1 is provided with annular groove 2, and handle 8 is arranged on the annular groove 2 of housing 1 rotationally; Handle rotary knob 5 is hinged on handle 8 through back-moving spring 6; The interior circle of said housing 1 connecting portion is provided with three stopper slots 3 that are mutually 90 degree, and middle stopper slot 3 is in directly over housing 1 connecting portion, and the stopper slot 3 of two sides is in the horizontal direction of housing 1 connecting portion; The latch part and the stopper slot 3 of handle rotary knob 5 one ends are complementary, and the spacing head of handle rotary knob 5 other ends matches with the button of starting switch 7.The connecting portion of said housing 1 is provided with protruding block 4, and handle 8 is provided with the locating piece 9 that matches with block 4.
The utility model work is following: as depicted in figs. 1 and 2; For hand held electric tool is in off position; The latch part of handle rotary knob 5 is locked in the stopper slot 3 that advances housing 1 under the effect of back-moving spring 6; The spacing head of handle rotary knob 5 other ends is in released state with the button of starting switch 7, but this moment, handle 8 left-right rotation 90 were spent.If need the operating angle of left-right rotation handle 8; As shown in Figure 4; Can be by lower handle rotary knob 5, the stopper slot of the latch part of handle rotary knob 5 and housing 1 was opened in 3 minutes, and handle 8 is in rotatable state with housing 1; At this moment, the spacing crown of handle rotary knob 5 other ends is on the button of starting switch 7.In the middle of rotation process, as shown in Figure 5, the button of starting switch 7 is lived on the spacing crown of handle rotary knob 5 other ends, and assurance can't be pressed starting switch 7.When handle 8 rotates 90 degree to the left or to the right; Locating piece 9 on the handle 8 receives housing 1 protruding block 4 to be stopped; Meanwhile; The latch part of handle rotary knob 5 under the effect of back-moving spring 6 again lock advance the left side of housing 1 or the stopper slot 3 on right side, accomplish handle 8 left or dextrad rotate the work of 90 degree, thereby the problem that starts suddenly when having solved rotation.
As shown in Figure 3; When hand held electric tool is worked, press starting switch 7, after starting switch 7 starts; The latch part of handle rotary knob 5 is locked the into stopper slot 3 of housing 1; The button of the spacing epicranium starting switch 7 of handle rotary knob 5 other ends blocks, and guarantees that handle rotary knob 5 can't press release, the problem of rotation suddenly when p has solved work.
