The specific embodiment

Fig. 1 has illustrated a kind of guider 10a with pilot unit 16a and guard shield device 20a with stereogram, this guider is used to sting the hand held power machine 12a of saw 14a form, this guard shield device 20a is designed to the housing 66a of hand held power machine 12a, and is provided with the CD-ROM drive motor that is not shown specifically here in this guard shield device.This pilot unit 16a has one and is parallel to the principal spread direction 24a that guard shield device 20a's or housing 66a's principal spread direction 22a extends, and wherein, this pilot unit 16a is set for direct reception and guiding plug-in cutter 18a.

In addition, this thorn saw 14a has a driver element 68a, and this driver element provides along the reciprocating motion on the vibration-direction 28a, thereby does elevating movement continuously at the reciprocal device 30a of work driving in service, for example reciprocating lever of thorn saw 14a.This reciprocal device 30a has a cutter receiving element 70a, plug-in cutter 1 8a of this cutter receiving element carrying thorn saw blade 62a form.

At the sliding members 46a of the slide form that is provided with on the downside 72a of cutter receiving element 70a of attaching troops to a unit of housing 66a, the pilot unit 16a that is used for plug-in cutter 18a removably is fixed on this sliding members by a screw thread that is not shown specifically.This pilot unit 16a has two

matrix

54a, 56a, and these matrixes respectively have principal spread direction 58a, a 60a, and these principal spread directions are arranged mutual vertically.This pilot unit 1 6a or matrix 56a have one with pilot unit 1 6a or the director element 32a that constructs integratedly with matrix 56a, this director element is configured to the profiled member of U-shaped profile, wherein each extends along a saw blade side 76a arm 74a of U (arm only is shown in Fig. 1) on principal spread direction 24a, and the base section of U (at length not illustrating) extends along saw blade back side 78a perpendicular to principal spread direction 24a.Be arranged on by the profiled member with the U-shaped profile on three sides of plug-in cutter 18a, this director element 32a receives plug-in cutter 1 8a with a width 80a, and this width is equivalent to the width 80a of director element 32a, makes matrix 56a obtain guide function thus.By director element 32a or by means of plug-in cutter 18a is inserted in the profiled member of U-shaped profile, pilot unit 16a can stop plug-in cutter 18a to move on direction 26a, and this direction 26a is perpendicular to guard shield device 20a's or housing 66a's principal spread direction 22a and perpendicular to the reciprocal vibration-direction 28a of device 30a.

For this reason, this hand held power machine 12a or this pilot unit 16a have a retaining element 44a, and this retaining element is fixed on this pilot unit 16a on the sliding members 46a by the screw thread that does not illustrate.Therefore this retaining element 44a is made of matrix 54a and extends perpendicular to guard shield device 20a's or housing 66a's principal spread direction 22a.In addition, this retaining element 44a determines maximum working depth 82a by its layout with respect to cutter receiving element 70a, determines thus, only has plug-in cutter 18a to pass described workpiece 42a during the processing of workpiece 42a.

With stereogram a kind of guidance set 38a has been shown in Fig. 2, it is used for the hand held power machine 12a that comprises pilot unit 16a is led and is used for carrying out otch 84a with the straight line of cut of workpiece 42a.For this guiding, this guidance set 38a has a guide device 50a, this guide device is configured to metal slide, and hand held power machine 12a can be supported on the upside 86a of this guide device or be directed on the direction of motion or operative orientation 88a by its sliding members 46a.In addition, guarantee this guiding by a gathering sill 90a, this gathering sill is extending and this gathering sill is seen on vibration-direction 28a by plug-in cutter 18a and pilot unit 16a in the course of the work and passed (referring to Fig. 3) along guide device 50a on the operative orientation 88a.On the 92a of the end of guide device 50a, the immobilising device 96a of rod type is set perpendicular to guide device 50a on downside 94a, this bar is put guide device 50a device 98a and is connected with putting, and this is put and puts device and be used for working face upper support guidance set 38a at for example desk.Put and put the adjusting device 100a that device 98a is provided with wooden semi-circular disks form, the operator can regulate devices use by this and be arranged on and put the control stick 104a of putting on the device 98a goes out to be used for the otch 84a of workpiece 42a in dial 102a adjusted the cutting angle of expectation.

For holding workpieces 42a, this guidance set 38a has wooden bearing unit 40a, and this bearing unit is made of the angled component assembly 106a that has by touching member 108a and supporting member 110a.This supporting member 110a can be with regulating the round member 112a interruption that device 100a regulates by one, this round member is used as bearing-surface equally, in this round member, be provided with a slit 114a who in operative orientation 88a, extends, in the process of processing work 42a, plug-in cutter 18a leads in this slit, so that carry out otch 84a along operative orientation 88a and on vibration-direction 28a.Can regulate this round member 112a by rotary actuator spare 100a, therefore regulate slit 84a and therefore regulate the cutting angle of expecting.By rotation, the guide device 50a of guidance set 38a can swingingly be supported on 180 ° scope 52a and guide device and slit 114a are conditioned similarly, thereby can realize the good guidance to plug-in cutter 18a with regard to the otch 84a that expects.

Figure 3 illustrates system 48a with hand held power machine 12a and guidance set 38a, this hand held power machine 12a has a pilot unit 16a, and this system is in the layout that is used for implementing passing the otch 84a of workpiece 42a, wherein, for the sake of clarity, otch 84a is implemented at this.

Guider 10a's or guidance set 38a's two optional embodiments have been described in Fig. 4 to 6.On substantially the same member, feature and the functional principle to represent to identical Reference numeral.And in order to distinguish these embodiment, alphabetical a to c is added in the Reference numeral of these embodiment.The following description is limited to the difference of the embodiment among Fig. 1 to 3 substantially, wherein, and can be about identical member, feature and function with reference to explanation to the embodiment among Fig. 1 to 3.

Show the guider 10b that is used to sting the hand held power machine 12b that saws the 14b form with cutaway view at Fig. 4, this guider 10b has a pilot unit 16b and has a guard shield device 20b who is integrated among the guidance set 38b, so that carry out at this otch that passes a workpiece 42b that does not illustrate.This pilot unit 16b and guidance set 38b have constituted the 48b of system with hand held power machine 12b.

This guidance set 38b has the guard shield device 20b of base section 116b form, and two arm 120b, 122b that extend perpendicular to base section 116b extend on the opposed end 118b of this guard shield device.On corresponding, the opened end portions 124b of arm 120b, 122b, arm 120b, 122b respectively constitute a bearing-surface that is used to have the guide device 50b of gathering sill 90b, wherein, hand held power machine 12b is directed to being bearing on the guide device 50b or on operative orientation 88b during the processing work 42b.This guide device 50b puts by immobilising device 96 and to be put device 98b and is connected, and the base section 116b of guidance set 38b is bearing in this and puts and put on the device.
