Shape ground is constituted.But it is also recognized that damping element 24 thinks significant other design forms, such as conduct with technical staff
Polygon with circular dead slot etc..The here of pilot unit 14 has at least one director element 26, and damping element 24 is arranged
On director element.Pilot unit 14 has two director elements 26,28 altogether, wherein, damping element 24 is arranged on the two
Director element 26, one of 28 is upper (Fig. 2).But it is also recognized that pilot unit 14 has leading different from the quantity of two
To element 26,28.Director element 26,28 is configured to straight-line guidance post.In addition it is contemplated that damping unit 22 has two damping units
Part 24, wherein, each damping element 24 is arranged on two director elements 26, one of 28.Director element 26,28 is in assembling shape
At least substantially extend parallel to each other in state.In addition, director element 26,28 is at least substantially orthogonal to prop up in confined state
The bearing-surface 58 of bearing unit 12 extends, and bearing unit 12 is bearing on workpiece by the bearing-surface when workpiece is processed.It is oriented to unit
Part 26,28 is regularly connected by the ways and means that press-fit connection is had been known with technical staff with bearing unit 12.
This, director element 26,28 is configured to hollow cylinder.The ways and means that spring element 16,18 is had been known with technical staff
In being arranged on director element 26,28.In addition multiple guide posts 60,62 of pilot unit 14 are arranged in director element 26,28.Lead
Surrounded by spring element 16,18 to bar 60,62 heres.Spring element 16,18 is supported on by an end leads accordingly respectively
To on element 26,28 and/or bearing unit 12 and spring element 16,18 is respectively supported at by another end and is led accordingly
Taking on protuberance 64,66 to bar 60.Guide post 60,62 respectively back to the side of bearing unit 12 regularly with housing list
Unit 20 connects.
When workpiece is processed by hand tool 10, in order to cut off workpiece microgranule, housing unit 20 overcomes spring element
The spring force of part 16,18 towards the direction of bearing unit 12 is moved, desired and thick by milling depth before until reaching
The cutting depth for adjusting unit 42 to adjust out.After desired cutting depth is reached, housing unit 20 is associated with leading by one
Fixed relative to bearing unit 12 with the ways and means that technical staff has been known to the clamping element of element 26, one of 28
In one location.Next when needed cutting depth can again be adjusted by milling depth accurate adjustment unit 40.When housing list
Unit 20 towards bearing unit 12 direction move when, housing unit 20 is directed to by pilot unit 14.Here, spring element
16th, 18 compressed and guide post 60,62 in straight-line guidance post 26,28 relative to director element 26,28 move.Housing rounding
20 surround director element 26,28 by the guiding area 68,70 of housing unit 20.Therefore, the excircle of director element 26,28 exists
Slide on the guiding area 68,70 of housing unit 20 in the motion of housing unit 20.The here of damping element 24 is arranged on two
On the excircle of director element 26, one of 28.Therefore, damping element 24 be arranged on housing unit 20 guiding area 68,70 it
In one region.In addition, damping element 24 is movingly supported by relative to director element 26,28.Here, damping element 24 can
It is bearing on director element 26 to motion, damping element 24 is arranged on the excircle of director element.
When housing unit 20 is moved towards the direction of bearing unit 12, damping element 24 is same towards bearing unit 12
Move in direction.Here, housing unit 20 has at least one portable element 30 (Fig. 3), the portable element is arranged in shell
Body unit 20 makes damping element 24 towards bearing unit when moving towards bearing unit 12 against the spring force of spring element 16,18
12 direction motion.Portable element 30 is made up of the annular shoulder 72 of housing unit 20, it be arranged on housing unit 20 towards
On the inner side of damping element 24.But it is also recognized that portable element 30 thinks significant other design shapes with technical staff
Formula.
In addition, there is damping unit 22 at least one backstop energy to introduce element 32, it is arranged for backstop energy
It is incorporated in large area (Fig. 3) in damping element 24.There are damping unit 22 two backstop energy to introduce element 32,74 altogether.
These backstop energy introduce the disk that element 32,74 heres are configured to annular.Damping element 24 along one at least substantially
The direction extended parallel to lifting axis 34 is arranged on backstop energy and introduces between element 32,74.Therefore, backstop energy introduces unit
Part 32, one of 74 is arranged on the side towards bearing unit 12 of damping element 24 in confined state and backstop energy draws
Enter element 32, one of 72 to be arranged on back on the side of bearing unit 12.Backstop energy introduces element 32,72 in damping element 24
It is driven in motion.The here of portable element 30 of housing unit 20 is when housing unit 20 is moved towards the direction of bearing unit 12
Act on backstop energy to introduce on element 74, the backstop energy introduces element and is arranged on back on the side of bearing unit 12.Separately
Outward, damping element 22 has a stopping element 76, and it is arranged for limiting damping element 24 in motion away from supporting
Motion on the direction of unit 12.The here of stopping element 76 is configured to locating snap ring, and it is arranged on a groove of director element 26
In 78, damping element 24 is moveably supported at thereon.
When housing unit 20 after pinching screw 48 is released due to pilot unit 14 spring element 16,18 spring force
And when moving away from the direction of bearing unit 12, damping element 24 and backstop energy introduce element 32,74 by guide portion
Domain 68, one of 70 is same towards moving away from the direction of bearing unit 12, until being arranged on the side of bearing unit 12
Backstop energy introduces the backstop of element 74 on stopping element 76.Due to housing unit 20 kinergety and due to spring element
16th, 18 spring force in the effect on the direction of bearing unit 12, damping element 24 is pressed when housing unit 20 rebounds
Contract and damp the impact energy of the housing unit 20.
