Definitions
- the utility model relates to a fixing device for a rear handle for electrical tools, especially angle grinders.
- a fixing device for a rear handle is known from Angle grinding machines, which is described under DE 4022668 A1.
- inner grooves and inner teeth are made on the front and inside of the handle, wherein guide teeth are arranged in the inner grooves, also carried out on the main body, and the inner teeth, also carried out on the main body, are arranged in guide grooves with a fixing lever mounted on the top in the front part of the handle, which is connected to the fixing device arranged on the inside in the handle
- the fixing lever is mounted on the underside of the handle.
- a locking device is provided, which is used to fix it in a normal position during work.
- the task of the utility model is a fixing device for the handle of electric hand tools to create a secure fixation in the chosen location guaranteed and a possibility of an unwanted Switch on the electric hand tool while turning the handle excludes.
- the task is by means of a fixing device for the handle of Electric hand tools solved, which consists of a two-part housing the front and inside of which are arranged internal teeth and internal grooves.
- the internal teeth on the main body are in the guide grooves arranged.
- In the longitudinal grooves there is Possibility of the front part of a swivel mounted Fixing plate, the rear part of which is supported by a compression spring, lock.
- a rotary lever is fixed in the middle of the fixing plate attached, at the free end of a longitudinal opening is made.
- a guide pin moves that is fixed to the top of a double arm lever attached and mounted on a supporting hinge.
- the lower part of the Double arm lever is located above the on and off switch.
- the advantage of the fixing device for the handle for electrical tools is that they fix securely in the chosen position after turning the Grab handles guaranteed.
- Another advantage of the facility is that an unwanted switching on of the electric hand tool while turning of the handle completely excluded and therefore the prerequisite for Work accidents are avoided.
- the fixing device from a two-part housing with inner teeth on the front and inside (2) and inner grooves (3) are arranged.
- the inner, on the main body (15) executed teeth (2) are arranged in the guide grooves (4).
- Guide teeth (5) are arranged in the inner grooves (3), also on the main body (15) Guide teeth (5) arranged.
- On the guide teeth (5) are in one certain distance longitudinal grooves (6), the depth of which is the same Guide grooves (4).
- the front part of a pivotally attached fixing plate (7) to engage. Its rear part is supported by a compression spring (8).
- a rotary lever (9) is fixedly attached to the middle part of the fixing plate (7), a longitudinal opening (10) is formed at its free end.
- Guide pin (11) which is fixed to the upper part of a double arm lever (12) is appropriate.
- the double arm lever (12) is on a supporting hinge (13) stored.
- the lower part of the double arm lever (12) is above the one and Switch (14) arranged.
- the fixing device for the handle for electrical tools works in the following way. If necessary, the electric hand tool can Press the end of the fixing plate (7) using the pressure spring (8).
- the front part of the fixing plate (7) comes from the appropriate longitudinal groove (6) and the handle can be in the desired Location can be rotated.
- the rotary lever (9) moves upwards by pressing the Double arm lever (12) rotates and thereby the on and off switch (14) unlocked.

Abstract
Description
Bei einer varianten Ausführungsform ist der Fixierungshebel an der Unterseite des Haltegriffs montiert. An seinem freien Ende ist eine Rasteinrichtung vorgesehen, die für seine Fixierung in normaler Lage während der Arbeit dient.
Ein Nachteil der so beschriebenen Konstruktion besteht in der Möglichkeit den Fixierungshebel bei engedrucktem Startknopf während der Arbeit zu lösen, wobei eine Gefahr für den Bedienenden entstehen kann. Das betrifft insbesondere die variante Ausführungsform, bei der das Verschließen des Spannhebels mittels der Fixiereinrichtung konstruktionsmässig nicht vorgesehen worden ist . Ein anderer Grundnachteil ist es, dass die geschützte Konstruktion ermöglicht, den Haltegriff in eingeschaltetem Zustand in eine andere Lage zu drehen wobei eine reale Voraussetzung für einen Arbeitsunfall entsteht.
