The handle of expression can be adorned fixedly a cutter head or a replacing bar in Fig. 1 to 7.Cutter head or replacing bar are installed in the cutter head mount pad 23.The working method of the replacing bar that detailed description can here be used in DE 10233866.3, therefore, the disclosed content of this application here is included in the application fully.
Handle is made up of two parts basically.Handle portion 1 is a core body spare.Handle portion 2 is sleeve members.A hole 3 is arranged in sleeve member 2.Cavity walls 13 has some concane gaps 24 at outer wall side, and filling embeds flexible plastic in these concane gaps 24.Cause two to be in the embedding lattice chain (Felderketten) that front and back position is made up of flexible plastic thus.Between these two embedding lattice chains, establish the handle section of diameter maximum.In the zone that is in local diameter increase section was stitched in the boundary of overcoat one side, this diameter increase section is direct to be connected with hand sth. made by twisting district between two handle portions 1,2.Handle jacket constitutes two opposed manipulation districts 8 in the recessed section of the annular of centre by its flexible plastic insertion.Below each flexible plastic insertion, the bottom of concane gap 24 is provided with the free otch 25 of U-shaped.Constitute a control arm 14 based on this otch 25.Manipulation projection 15 of radially inwardly stretching out of free end design of control arm 14.
Handle portion 1 has the core body 4 cutter head being installed or being changed bar.Described core body inserts in the hole 3 under closed position shown in Figure 3 fully.There are a plurality of clamping frame lattice that extend vertically in the core body outside.A crewdriver attachment 11 is arranged in each clamping frame lattice.These driver bits of open position (see figure 5) at the storage chamber 6 that is become by these clamping frame lattices can be removed or insert again.
Each clamping frame lattice are separated each other two extend for elasticity tongue 5 respectively along the opposed wall 10 of diameter.These elasticity tongues 5 have radially outwards directed lock dog 9.The closed position of representing in Fig. 3 or Fig. 4, these two lock dogs 9 are in before the stopping step 7 of handle portion 2.Stop two handle portions 1,2 to move each other vertically thus.Have only by radially acting in two radially opposed soft districts 8 simultaneously, could make lock dog 9 leave the tracks of stopping step 7 by the deflection of control arm 14, thereby allow two handle portions 1,2 axially to relatively move to the pressure of interior orientation.For realizing this point, handle projection 15 and radially inwardly masterpiece is used on the elasticity tongue 5, make their elastic deflections.
If the kayser between two handles 1,2 is cancelled by pressurizeing in two opposed soft districts 8 simultaneously as mentioned above, then spring 16 expansion that can relax.The expansion of compression spring 16 causes partially opening the position that storage chamber 6 is represented in Fig. 2.Lax fully at this position compression spring 16.
Can reach the fully open position of representing among Fig. 5 by on two handle portions 1,2, applying axial tension.In the terminal stage towards the direction dislocation of this fully open position, the manipulation projection 15 of control arm 14 is crossed the stop protrusion 18 on the core body 4.At this fully open position, handle the sidewall retaining of projection 15 and lean against on the backstop 19 in the back.The leading flank of handling projection 15 is the inclined-plane.Equally, the trailing flank of backstop 19 also is the inclined-plane.These two inclined-planes work the inclined-plane that climbs jointly when assembling two handle portion insertings for handle.
In order to close storage chamber 6 again, the handle portion 2 with hole 3 must move with respect to handle portion 1 vertically.Here overcome by stop protrusion 18 and the kayser of handling protruding 15 actings in conjunction formation by axial compressive force.
The closed position of representing among Fig. 4 reaches like this, that is, and and the inclined-plane mating reaction of inclined-plane and stopping step 7 by lock dog 9.These two mutual slippages in inclined-plane of terminal stage at closing movement.This with elasticity tongue 5 radially the elastic deflection of inward direction combine.
In the handle of Fig. 8 to 13 expression, the cancellation of kayser state realizes that by pressurization on button 8 button 8 is located at the distolateral of handle portion 2.Handle portion 2 has an inner cavity 3.The core body 4 of second handle part 1 inserts in the hole 3.Core body 4 has some storage chambers that are used for driver bit 11 6 along circumferential array.Each storage chamber 6 separates each other by wall.In addition, core body 4 has a hole that is used to insert cutter head.Core body 4 also has the section of extending axially 31 in the wings, and it bears altogether four along the opposed elasticity tongue 5 of diameter.Each elasticity tongue is designed to a lock dog 9 that control inclined-plane 30 is arranged respectively.The inside that the section of extending axially 31 is inserted helical compression spring 16, the overhang bracket of compression spring is on a step 34 of core body 4.The other end of helical compression spring 16 is bearing in the bottom in hole 3.By this compression spring 16, the direction of core body 4 being opened hole 3 towards handle portion 2 with spring force loads.
Core body has one to be the backstop that extends radially 32 of lug boss in form.In the radial position identical with backstop 32, also there is a backstop 33 in hole 3, and when spring 16 pressed off two handle portions 1,2, backstop 32 retainings leaned against on the backstop 33.3 wall radially inwardly stretches out backstop 33 from the hole.Core body 4 is axially movable but can not be contained in rotationally in the hole 3.Moment of torsion can be passed on the handle portion 1 from handle portion 2 thus.
There is a jar shape groove 26 end that handle portion 2 is designed to handle portion 2 round tip.A center through hole is arranged at the bottom of jar shape groove 26, and the fixed arm of button 35 stretches out by center through hole, and button applies spring force by compression spring 27 towards the opening direction of groove 26.The hook-shaped end section of fixed arm guarantees that button is axially fixed in in its set groove 26.
The manipulation projection of button 8 staggers the earth's axis in stretching into groove 26 with respect to fixed arm 35.In the closed position, handle projection 29 and be in elasticity tongue 5 before distolateral control inclined-plane 30.In the closed position, the elasticity tongue end section that is designed to lock dog 9 stretches in the groove 26 by this way by the base apertures of groove 26, that is, make lock dog 9 barbs live the edge of base apertures.This zone of being lived by lock dog 9 barbs constitutes stopping step 7.
(Fig. 9,10) compression spring 16 is compacted in the closed position.If push button under this state as shown in figure 11, then the control inclined-plane 30 of elasticity tongue 15 is subjected to handle projection 29 loadings.Along with pushing button 8, the end rib of handling projection slides along control inclined-plane 30.When sliding therewith, the end section of elasticity tongue 5 radially moves inward.As long as the end face of button 8 is in the top on slot opening limit 28, lock dog 9 just barb is lived the stopping step 7 that sets for them.In the time of only in the end face of button 8 is imbedded groove 26, elasticity tongue 5 radially inwardly just bends to such degree,, makes the kayser engagement of lock dog 9 disengagements and stopping step that is.Therefore compression spring 16 expands and the handle portion 1 that will have a core body 4 is displaced to open position shown in Figure 12 and 13, meets each other in this position backstop 32,33.At this open position, compression spring 16 also has preload in a small amount.
If from the open position of Figure 12 and 13 expressions, core body 4 moves in the hole again, then compression spring 16 is compacted.Control inclined-plane 30 acts on the chain of command of stopping step 7 inclinations.Insert the terminal stage of motion at core body 4 in hole 3, lock dog 9 barbs are lived the stopping step 7 that sets for them.Control inclined-plane 30 in this case along sliding on stopping step 7, barb is lived stopping step until 30 quick-actions ground, control inclined-plane.
All disclosed features () own all are the invention main points.Also comprise relevant/appended disclosed content of priority document (copy of application documents formerly) in the disclosed content of the application all sidedly, also for this purpose, the feature of these data also is absorbed in claims of the application.
