Abstract
The invention relates to a hand machine tool with a motor which is held in a housing (12) and a tool (16) which can be driven by the motor and has handles (13, 14) and a switch (17) for turning the motor on and off, and for setting different speeds thereof, can be handled in a more reliable, convenient and intuitive manner through the possibility of gradually switching the switch (17) by the handles (13, 14) which can be rotated from a starting position to an end position, in particular about its longitudinal axis (15).
Description
Technical field
The present invention relates to hand held power machine, it have one be received in instrument that motor in the housing, one drive by this motor, handgrip and one be used to connect and turn-off, in particular for adjusting the switch of different motor rotary speeds.
Background technology
The hand held power machine that is provided with the slide switch that is used to connect and turn-off motor is open, and this slide switch is looked operated moving displacement and can be made motor slack-off gradually or move surely with accelerating.
These known slide switches only can be operated through pressing operation by finger, and the operation finger that consequently is used for slide switch in the case can not be with the handgrip that grip hand held power machine with all strength.
Summary of the invention
According to the present invention; A kind of electric hand-held power tool has been proposed; It has one and is received in the motor in the housing, instrument, handgrip and a switch that is used to connect and turn-off this motor and is used to adjust different motor rotary speeds that is driven by this motor; Wherein: said switch can turn to a handgrip that rotates terminal location from a rotation initial position around its longitudinal axis by one and little by little regulate; Make that motor rotates with minimum speed when handgrip having been regulated a little rotational angle, and when being rotated further handgrip; Motor rotary speed is along with the increase of the rotational angle of handgrip little by little improves; In the said rotation terminal location of this motor at handgrip, obtain its maximum speed, wherein, rotation direction and sizing that a key projection of switch can be looked rotating casing through an annular wedge-like profile are to inwardly or outwards regulating.
The present invention has its advantage, and a kind of like this hand held power machine promptly is provided, and its motor or its rotating speed can come break-make or adjusting by the rotation of whole handgrip, leave handgrip and need not one or more fingers.Therefore, this hand held power machine can especially reliably and accurately be handled and gripped, and motor rotary speed can be conditioned especially delicately simultaneously.
Rotating handgrip is as Top carry handle and/or as auxiliary handle, thus, selectively regulates rotating speed with one or another operator.
Auxiliary handle can rotate and be connected with the switch adjustable ground around its longitudinal axis, therefore, can be as using the autobicycle gasoline throttle swing handle regulate rotating speed.
Rotating handgrip can be fixed aspect rotation, thus, for example on the operating position of difficulty, can make operator drop into high power and operate, and come work with selectable, lockable rotating speed in the case.
Handgrip is rotated adjusting with can surmounting locking, thus, can step by step and can repeatedly regulate desired rotating speed.
Top carry handle and auxiliary handle selectively are used for by-pass cock, and thus, hand held power machine can operatively be used on the different working position especially flexibly and easily.
Top carry handle and auxiliary handle can be determined and be used for by-pass cock side by side, and thus, hand held power machine also can be advantageously used in unconventional operating position.
Top carry handle and/or auxiliary handle are provided with abreast or laterally and/or selectively can be provided with abreast or laterally with respect to the direction of feed of hand held power machine, thus, can use hand held power machine and operation cosily in the case very neatly.
Handgrip is connected with housing through the oscillation damping parts, thus, can be noninductive tired work and realizes special operation comfort.
Rotating handgrip is inner and/or on an especially axial end, have an operating means of a chute-type; Be used for moving the key or the button of the switch that can regulate gradually; This operating means adapts to the switch element that can regulate gradually that tradition is made; Thus, can be directly this switch element be arranged on the end of inside or handgrip of handgrip, and---available new mode operatively---performance desired function in the case.
Description of drawings
Describe the present invention in detail by an embodiment who has accompanying drawing below.Accompanying drawing is represented:
Fig. 1 is according to a side view of superfine milling machine of the present invention,
First viewgraph of cross-section of Fig. 2 rotary type handgrip, and
Second cross-sectional view of Fig. 3 rotary type handgrip.
The specific embodiment
The side view of a hand held power machine 10 shown in Fig. 1 reflects a hand-held superfine milling machine; Its housing 12 has band longitudinal axis 15, microscler, i.e. that point to, columniform, rotating Top carry handle 14 on direction of observation backward to the right in upper area; And be provided with a grinding dish 16 in the bottom, be used to receive the abrasive sheet 18 that a surface of the work grinding is used.From Top carry handle 14 center back draw a cable 20 that is used for motor power supply.And on the shell area of the back lower place of housing 12, stretch out a dust collecting container 22 backward, be used to be received in the grinding dirt bits that form when working with hand held power machine.Stretch out a zone as auxiliary handle 13 nose, housing 12 forward.
Fig. 2 shows its rotating casing 141 with one first cross section of Top carry handle 14; This rotating casing has on its circular interior profile 142 that some are flexible protruding 144, and these convexities extend in the outline 146 of gear-like of a columniform supporting mass 148 and cause the rotation with the mode that surmounts locking of the selected turned position of rotating casing 141 to be regulated or fixing.
Fig. 3 is illustrated in second cross section in the zone of an on & off switch 17, that have the Top carry handle 14 of its rotating casing 141 and supporter 148, but key projection 171 radial elastics of this on & off switch 17 are moved with resetting and on its adjustment stroke, can improve or reduce the rotating speed of motor.For this reason, this key projection 171 look rotating casing 141 through an annular wedge-like profile 145 rotation direction and sizing to inwardly or outwards regulating.
