Part 82,84 is at least substantially arranged in parallel to each other.In addition lever supporting element 82,84 respectively with one back to supporting member
46th, one of 48 end is movably disposed on switch pawl element 16.Switch pawl element 16 includes for this switching ratchet
Supporting member 86,88, they are connected with the end of supporting member 46,48 to be movably arranged in supporting member 46,48
On switch pawl element 16.Switch pawl-bearing element 86,88 is configured to bolt shape.In addition switch pawl-bearing element 86,88
It is integrally formed with switch pawl element 16.But it is also recognized that switch pawl-bearing element 86,88 and switch pawl element 16
Dividually constitute and by one kind for technical staff seem significant connected mode, for example by shape sealed and/or
Force closure is connected with switch pawl element 16 with being connected.It is single that bearing unit 38 also includes the supporting of at least one parallelogram
Unit 54.Parallelogram bearing unit 54 has at least one parallelogram supporting member 56, and it is arranged for basis and opens
The motion closing pawl element 16 carrys out the operating area 52 of Operation switch element 18.Operating area 52 is opened by one of switch element 18
Close push rod to constitute.Additionally, the blocking element 32 of switch element 14 is arranged on and is used for switching spine on parallelogram supporting member 56
The motion locking of pawl element 16.Parallelogram bearing unit 54 altogether have at least two parallelogram supporting members 56,
58.Parallelogram supporting member 56,58 is made up of lever supporting element 82,84 here.Because switch pawl element 16 is subject to
To the supporting of parallelogram bearing unit 54, the longitudinal extension direction 26 switching pawl element 16 is with respect to hand tool
10 being oriented in of principal spread direction 66 is maintained when being operated by operator all the time.Therefore, switch the operation of pawl element 16
Face 92 is equally kept due to the operation switching pawl element 16 all the time with respect to handling orienting of housing 36.
In order to start hand tool 10, releasing member 20 goes out from a centre position (Fig. 3) of releasing member 20
Send out in this centre position blocking element 32 in the operation to switch pawl element 16 backstop the one of releasing member 20
In individual latch surfaces 94 and thus at least farthest stop the motion of switch pawl element 16 around axis of oscillation 22
Swing in a unlocked position (Fig. 4) of releasing member 20.Thus make unblock receive dead slot 30 and move in a position, edge
The direction observation that the axis of oscillation 22 at least substantially parallel to releasing member 20 extends, unblock in this position receives dead slot
One of 30 are alignd with blocking element 32 with flushing.Therefore, blocking element 32 can be due to entering to the operation switching pawl element 16
Enter to unblock and receive in one of dead slot 30 so as to realizing switch motion on the direction handling housing 36 for the pawl element 16.
From there through releasing member 20 around the oscillating motion solution lock-switch pawl element 16 of axis of oscillation 22 motion locking.By one
After the individual unblock in motion locking from operator switch pawl element 16 the switch pawl element 16 that causes of operating physical force to
Set about the motion in the direction housing 36, switch pawl element 16 moves around the axis of movement 28 of switch pawl element 16.?
Here, the operating surface 92 of switch pawl element 16 is due to parallelogram bearing unit 54 at least substantially maintained switch ratchet unit
The longitudinal extension direction 26 of part 16 orients with respect to the angle of the outer surface handling housing 36.
Releasing member 20 is swingably supported at least two mutually different directions around axis of oscillation 22
Carry out switching the motion locking of pawl element 16.Switch element 14 also has at least one spring element 96, and it is in releasing member
On the direction in 20 centre position, a spring force is loaded to releasing member 20, in the fortune of centre position breaker in middle pawl element 16
Move and be farthest prevented from by motion locking.Spring element 96 is preferably constructed in rotating spring.In addition switch element 14
In order to form safety switch function, there is an other spring element 98.This other spring element 98 is configured to, because
The operating physical force of operator can cancelled for spring force in the effect switching on pawl element 16 on switch pawl element 16
Effect after make switch pawl element 16 move to switch pawl element 16 towards one back to the direction handling housing 36
In initial position.Here, this other spring element 98 is by a switch plunger to switch element 18 of switch element 18
The spring element of spring loaded is constituted.Therefore this other spring element 98 applies one by parallelogram supporting member 56
, on switch pawl element 16, this parallelogram supporting member is because switch pawl element 16 is towards handling housing for individual spring force
The motion in 36 direction and the construction of Operation switch element 18 are the operating area 52 of switch plunger.Thus make switch pawl element
16 move towards back to the direction handling housing 36 after cancelling the effect of operating physical force of operator.Due to switching pawl element
16 move to centre position towards the spring force back to the motion handling housing 36 and due to spring element 96, releasing member 20
In.Therefore switch element 14 is located in an initial position, passes through fortune in the motion of this initial position breaker in middle pawl element 16
Dynamic locking is at least prevented from as much as possible.
It is conceivable, that portable in a kind of shift design scheme not being shown specifically here of hand tool 10
Toolroom machine 10 has in addition to mechanical movement blocking device that one electric and/or the starting blocking device of electronics, for example once
One sensor unit of hand tool 10 sense except one be manually placed at handle housing 36, especially handle handles
Outside on region 64, the another handss of operator are placed on and add the control handling on 76 and from there through hand tool 10
And/or adjustment unit disables electricity and/or electronics starting locking, this electricity and/or electronics starting blocking device can
Realize energising to driver element 72, so as to realizing the starting of hand tool, control and/or adjustment unit analysis and
Process the characteristic quantity sensing.
