Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Fig. 1-2 is referred to, Fig. 1 is the structural representation of the embodiment of the utility model internal angle wrench one, and Fig. 2 is that this practicality is new
Type internal angle wrench coordinates the structural representation of an embodiment with interior corner bolt.
In the present embodiment, internal angle wrench 100 includes：The auxiliary section 101 of one bending connection and operating portion 102, coordinate
Portion 101 makes internal angle wrench 100 fix bolt coordinating with the decorative pattern sectional hole patterns of interior angle bolt head, tighten so as to reaching or
Unscrew the purpose of interior corner bolt；Operating portion 102 is the handgrip part using the internal angle wrench 100, while is also to apply moment of torsion
Position.
Alternatively, internal angle wrench 100 can be inner hexagon spanner, in the present embodiment, auxiliary section 101 and operating portion 102
It can be a linear plastic material, such as steel, material section shape is processed as regular hexagon, being formed by bending forming should
Auxiliary section 101 and the operating portion 102, herein bending are in 90 °；Therefore, auxiliary section 101 and the cross sectional shape phase of operating portion 102
Together, in the present embodiment, the cross sectional shape of auxiliary section 101 coordinates the regular hexagon decorative pattern on hexagon socket head cap screw head for regular hexagon
Hole, fix hexagon socket head cap screw.
Certainly, as skilled in the art to understand, the cross sectional shape of the auxiliary section 101 can be arbitrary polygon, full
Sufficient cross sectional shape is corresponding with the decorative pattern sectional hole patterns of bolt head, can play a part of fixing bolt.It is appreciated that
It is that the overall structure of the auxiliary section 101 in the utility model embodiment and operating portion 102 is exactly that the common guiding that is not provided with is tied
The spanner of structure.
In the present embodiment, the end of auxiliary section 101 is provided with guide frame, and the guide end of guide frame is prior to auxiliary section
101 are set in the periphery of interior angle bolt head to be tightened, so that the end of auxiliary section 101 is easy to and interior angle bolt head to be tightened
Decorative pattern hole coordinate positioning.
Alternatively, guide frame can include linkage section 103 and guide section 104, linkage section 103 respectively with auxiliary section 101
And guide section 104 connects, the end structure annular in shape of guide section 104.The end of auxiliary section 101 is located at the end of guide section 104
Within face, so that the end face of guide section 104 is prior to the ends contact of auxiliary section 101 interior angle bolt head to be tightened, and then play
Guide effect, so that the end of auxiliary section 101 is easy to and the decorative pattern hole of interior angle bolt head to be tightened coordinates positioning.
Alternatively, internal angle wrench 100 coordinates as shown in Figure 2 with interior corner bolt 201.
Fig. 3-4 is referred to, Fig. 3 is the structural representation of the utility model auxiliary section and the embodiment of linkage section connected mode one
Figure, Fig. 4 is the structural representation of the utility model auxiliary section and another embodiment of linkage section connected mode.
Alternatively, auxiliary section 301 is set through linkage section 302, as shown in figure 3, or the part of auxiliary section 401 through connection
Section 402 is set, as shown in Figure 4.
Fig. 5-6 is referred to, Fig. 5 is the structural representation of the embodiment of the utility model guide section one, and Fig. 6 is the utility model
The structural representation of another embodiment of guide section.
Alternatively, linkage section 501 and guide section 502 are structure as a whole, and guide section 502 can be hollow no bottom surface cylinder
Structure, as shown in figure 5, or guide section 601 is hollow no bottom surface round estrade structure, i.e. loudspeaker openning shape, certainly, opening is inclined
Angle of bevel needs are smaller, typically could be arranged to be no more than 10 degree compared to the inclination angle ∠ 1 of its center axis 602, such as
Shown in Fig. 6.
Alternatively, the distance of the end of auxiliary section 101 to the end of guide section 104 is 1.0mm~2.0mm, certainly, such as originally
Art personnel are understood, herein the distance of the end of auxiliary section 101 to the end of guide section 104 be according to internal angle wrench 100 with
And depending on the size of interior corner bolt, different numerical value can be set for different internal angle wrench 100 and interior angle Bolt sizes
Scope, it is therefore an objective to be the end of guide section 104 bolt head to be tightened prior to the ends contact of auxiliary section 101, so that auxiliary section
101 are easier to the decorative pattern hole on fitted bolt head.
Alternatively, the end outer diameter of guide section 104 is more than bolt head diameter 0.8mm~1.0mm, guide section 104
Inner wall of end diameter be more than bolt head diameter 0.3mm~0.5mm.Obviously, the end inside and outside wall diameter of guide section 104 herein
Size be to be set according to the size of interior corner bolt, it is therefore intended that be directed to the area control of the end cyclic structure of section 104
Within the specific limits, make it easier for contacting bolt head, reach guide effect；The cyclic structure area of the end of guide section 104
It is excessive, it is unfavorable for the fitted bolt head decorative pattern hole of auxiliary section 101, the cyclic structure area of the end of guide section 104 is too small, can cause
Guide section 104 is arranged bolt head operating difficulties.
The utility model passes through the end set guide frame in internal angle wrench auxiliary section, the guide section end of guide frame
First it is set in interior angle bolt head periphery to be tightened so that the easy flower with interior angle bolt head to be tightened in the end of auxiliary section
Pit coordinates positioning, so as to improve the operating efficiency of spanner and safety in utilization.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is all
