Definitions
- the invention relates to a tool holder for an at least partially striking Hand tool device such as a chisel hammer or a drill bit for holding sometimes strikingly stressed tools such as hammer drill bits or chisels.
- Such strikingly stressed tools usually have as clamping ends at least one locking groove axially delimited on both sides in the tool shank, which a limited axial mobility of the tool within impact loads the tool holder.
- an associated tool holder engages in this locking groove with radially displaceable locking elements and locks them via a user-friendly axially movable locking sleeve.
- the Locking elements temporarily offset radially outwards and give the Tool shank free for axial removal. Both are used to remove the tool Hands of the user, which means that the hand tool, mostly on the knee, must be discontinued.
- the locking elements are axially counter to the force a spring by means of a freely rotatable sliding sleeve axially displaceable locking sleeve locked with two axially spaced release positions, in which the Locking elements can be moved. Both hands of the Users.
- DE3421811 is an axially movable locking sleeve over a rotatable locking element axially lockable and is replaced when inserting the Tool locked automatically.
- rotating hand tool devices it can be with one rotatable locking element by gripping the tool holder to one unintentional release of the locking device.
- the object of the invention is to implement a tool holder for a at least partially rotating and striking hand tool device which the tool securely locked even when rotating and removing the Tool.
- a tool holder for an at least partially rotating and beating hand tool device for holding a tool with a clamping end, which has at least one axially delimited locking groove for radial engagement of a locking element, an axially displaceable locking sleeve for radial locking of the locking elements engaging in the locking groove and an axially lockable locking element for the locking sleeve.
- This axially bistable click-clack mechanism for the locking sleeve is always only one hand needed to change the axial position of the locking sleeve, thereby this is now available for removing the tool.
- the locking element is advantageously radially biased axially lockable on a locking means, wherein further advantageously the locking element is designed as a leaf spring, which has a radial locking lug engages axially behind as a locking means.
- the latching element advantageously has a nose which is angled inwards on the drive side, which when inserting the changed tool, the locking elements axially in the Displace the locking groove, which locks the tool automatically.
- the locking sleeve is advantageously axially form-fitting with an axially by hand displaceable, freely rotatable sliding sleeve connected, creating a Torque transmission when attacking the tool holder is prevented.
- the axially displaceable locking sleeve with two axially spaced apart is advantageous Release positions for the temporary reception of the locking elements, which continue are advantageously formed as balls when removing or inserting the Tool carried out, so that insertion without manual operation of the sliding sleeve of the tool is made possible.
- a radial preloaded radial spring is advantageous in the tool-side disengagement position arranged, whereby the locking elements after removal of the tool be pushed back radially inwards.
- the tool holder 1 has a tool holder 1 for a rotating and striking Hand tool device 2 for receiving a tool 3 with a clamping end, which has two axially delimited locking grooves 4.
- the tool holder 1 also has an axially displaceable locking sleeve 5 for radially into the locking groove 4 engaging locking elements 6 in the form of balls and for the locking sleeve 5 an axially lockable locking element 7.
- the radial spring design Prestressed latching element 7 engages axially latchably behind a radial latch Locking means 8.
- the locking sleeve 5 is axially form-fitting with an axially by hand displaceable, freely rotatable sliding sleeve 9 connected against the force of a spring 10 offset on the drive side.
- Locking elements 6 are in the axial removal of the tool side Tool 3 temporarily through the drive-side limitation of the locking groove 4 in the Tool-side disengagement position 11a of the locking sleeve 5 displaced and press outside against a radially preloaded radial spring 12.
