Stop part 142 is provided with stop surface 154 on the end 141 near saw blade 36, as shown in Figure 7, and this stop surface 154 is vertical with first abutment face 65 on being formed at neonychium 88, also can acutangulate setting with first abutment face 65.Certainly, directly be formed on the first side wall 48 like first abutment face, same, first abutment face and this stop surface 154 also acutangulate setting.
Stop surface 154 with first oblique angle α 1 that cutting planes form equates with first abutment face 65 that with second angle 3 of the acute angle that said first abutment face 65 forms effect is following to be introduced.
Second angle 3 between the stop surface 154 and first abutment face 65 depends on first limit 161 that the workpiece W and first abutment face 65 lean and the angle between the workpiece abutment face 165; Because second angle 3 and first limit 161 equate with angle between the workpiece abutment face 165; Can so that workpiece W and stop surface 154 fit more, thereby the protection cutting accuracy.
And cutting for ease; Second abutment face 67 equates with second angle 3 that said first abutment face 65 forms with stop surface 154 with the second oblique angle α 2 that cutting planes forms; So; When workpiece be resisted against be cut on second abutment face 67 after, can be directly the cut surface of workpiece directly be resisted against on first abutment face 65 as workpiece abutment face 165 and cuts.
In the present embodiment, second angle 3 that the stop surface 154 and first abutment face 65 form is 45 degree, and certainly, angle also can be other angle between the stop surface 154 and first abutment face 65.This stop part 142 can be processed by the plastics of certain toughness, against workpiece the time, both can increase friction and prevent that workpiece from moving, and also can prevent the surface of the work that weares and teares.Certainly this stop part 142 also can be integrally formed with slide mass 146.
Retaining mechanism 144 comprises locking nut 156 that is arranged in the stop part 142 and the double-screw bolt 158 that cooperates with locking nut 156; Double-screw bolt 158 is cooperated with locking nut 156 by the hole that bottom 150 lateral surfaces of U-shaped sliding part 146 pass on the sliding part 146; Promoting stop part 142 closely cooperates with rule 72; The wall extension 152 that adds sliding part 146 matches with first side 78 of rule 72, thereby sliding part 146 is fixed on the rule 72.Locking for ease, the end of double-screw bolt 158 also is connected with the knob 159 of handled easily.
Reading for ease, like Fig. 7 and shown in Figure 8, this cutting attachment 40 also is provided with first pointer 160 and second pointer 170 that matches and use with scale value.
As shown in Figure 8, first pointer 160 is used to indicate that workpiece W is resisted against first limit 161 on first abutment face 65 cuts length in advance, and what just workpiece W went up relative longer sides cuts length in advance.Refer again to shown in Figure 4ly, first pointer 160 comprises the pointer portion 162 that is connected on the sliding part 146, and this pointer portion 162 points on rules 72 high scale values, thereby shows the length of the longer sides that current setting is good.In the present embodiment, pointer portion 162 is integrally formed with sliding part 146, and along with sliding part 146 slides along rule 72, is used to regulate Cutting Length.
As shown in Figure 9, what second pointer 170 was used to indicate workpiece W second limit 163 relative with first abutment face 65 cuts length in advance, also goes up relatively with regard to workpiece W and cuts length in advance than minor face.
Refer again to shown in Figure 4ly, second pointer 170 comprises installation portion 172, indication portion 174 and aligned portions 176.Wherein installation portion 172 is along linearly extended elongate rod with aligned portions 176.One end of this installation portion 172 and an end of aligned portions 176 link together, and form indication portion 174 in both junctions.Indication portion 174 points on the rules 72 high scale values, thereby shows and cut length in advance than minor face.Form the 3rd angle 4 between installation portion 172 and the aligned portions 176, in the present embodiment, the 3rd angle 4 is 45 degree.
When reality is used, need precise length or the precise length on second limit 163 on first limit 161 of workpiece W sometimes, so just need to use first pointer 160 or second pointer 170.As shown in Figure 8, because of the pointer portion 162 of first pointer 160 is installed on the sliding part 146, and pointer portion 162 point to corresponding scale be used to indicate workpiece W first limit 161 to cut length in advance more directly perceived.So can move sliding part 146 earlier during operation; Make the corresponding scale of cutting length in advance on pointer portion 162 sensings, first limit of the pointer 160 of winning; And through retaining mechanism 144 locking sliding parts 146; Place work piece W then, with first limit 161 of workpiece W and first abutment face 65 against, workpiece abutment face 165 and stop surface 154 back that leans just can have been cut.
