Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model provides a kind of box spanner, as shown in Fig. 1,2 and 4, including barrel housing 1,7 and of sleeve end cap
Handle 8, handle 8 are connect using the direct nested type of polygon with sleeve end cap 7, are determined as shown in fig. 6,7 rear portion of sleeve end cap is provided with
Position groove positions, and is provided with elastic bumps 10 on handle 8, elastic bumps 10 are oppositely arranged with positioning groove.7 rear portion of sleeve end cap
It is provided with groove positioning to cooperate with the elastic bumps 10 on handle 8, prevents the axial motion of handle 8 and quick detachable.Further, it covers
Cylinder 7 inner wall of end cap is provided with reinforcing rib 71.Barrel housing 1 and sleeve end cap 7 pass through circumferential fastening screw 9 and fasten, and work as sleeve shell
When 1 internal component of body damages, it is easily changed.
If if as shown in Figure 1, be disposed with inside barrel housing 1 dry-charged plates thimble 2, preceding guide plate 3, rear deflector 4,
Dry thimble spring 5 and fixed tailgate 6, fixed tailgate 6 are arranged at 1 rear portion of barrel housing, as shown in figure 5,1 inner wall of barrel housing
It is provided with convex block 11, fixed tailgate 6 is arranged at 11 rear of convex block and offsets with sleeve end cap 7.Several 5 one end of thimble spring are solid
The surface of fixed tailgate 6 is set calmly, the other end offsets with rear deflector 4, and the front of rear deflector 4 is arranged in preceding guide plate 3,
And it is provided with gap between rear deflector 4, if dry-charged plates thimble 2 and the surface of preceding guide plate 3 offset, preceding guide plate 3 is with after
The surface of guide plate 4 is provided with several pilot holes, if dry-charged plates thimble 2 is oppositely arranged with pilot hole and thimble spring 5.Often
The vertical cross-section of root sliding 2 front end of thimble is hexagon, and the vertical cross-section of every sliding 2 rear end of thimble is circle,
The pilot hole on preceding 3 surface of guide plate is hexagon, and the pilot hole on 4 surface of rear deflector is circle.Preceding guide plate 3 is led with after
It is welded in barrel housing 1 to plate 4, aperture is hexagonal structure on preceding guide plate 3, and aperture is circle on rear deflector 4
