Abstract
The utility model discloses a sleeve for disassembling a locking screw of a spare tire or a jack. A connecting rod matched with a pneumatic impact wrench is arranged on one end of the sleeve, and a hole slot matched with the top end of the locking screw is arranged on the other end of the sleeve; the hole slot consists of a polygonal hole and a strip-shaped channel, the polygonal hole is positioned at the axial center of the sleeve, and the strip-shaped channel is communicated with the polygonal hole in the radial direction and takes the center of the polygonal hole as a symmetric center; and the polygonal hole is adaptive to the top end of the locking rod with a polygonal top end in shape and size, and the strip-shaped channel is adaptive to the top end of the locking screw with a rod like top end in shape and size. The sleeve can conveniently disassemble locking screws with different shapes, is more convenient and simpler to operate, and can improve the disassembling work efficiency and reduce the slipping safety accidents as the locking screw is unscrewed.
Description
Technical field
The utility model belongs to repair outfit, is specifically related to a kind of sleeve that is used for dismounting spare tyre or jack tie down screw.
Background technology
When spare tyre that assembles different cars or jack; The spare tyre of different automobile types or the tie down screw of jack have difformity; Be illustrated in figure 5 as the tie down screw 4 on shaft-like top; Be illustrated in figure 6 as the tie down screw 5 on hexagonal top, and these two kinds of tie down screws of existing dismounting sleeve dismounting simultaneously cause efficiency of assembling low; In addition, when particularly assembling has the tie down screw on shaft-like top, the frequent landing of sleeve barrel tool that is used to tighten tie down screw, operation is inconvenience very.
Summary of the invention
The purpose of the utility model provides a kind of sleeve that is used for dismounting spare tyre or jack tie down screw, and this sleeve is convenient to the installation and removal tie down screw, and can improve efficiency of assembling.
The technical scheme of the utility model is following:
A kind of sleeve that is used for dismounting spare tyre or jack tie down screw, an end of said sleeve has the connecting rod that cooperates with pneumtic impact wrench, and the other end of sleeve has the hole slot that cooperates with the top of tie down screw; Said hole slot is made up of a polygonal hole and a bar-shaped trough, and polygonal hole is positioned at the axial center of sleeve, and said bar-shaped trough and polygonal hole radially connect, and is symmetrical centre with the center of polygonal hole; The shape size and the end shape size with the tie down screw on polygonal top of said polygonal hole adapt, and the shape size and the end shape size with the tie down screw on shaft-like top of said bar-shaped trough adapt.
Further, said polygonal hole is hexagonal hole or quadrilateral hole.
In use, this sleeve can adapt to the dismounting needs of different tie down screws, if the tie down screw on shaft-like top, then match with bar-shaped trough in shaft-like top; If the tie down screw on polygonal top, polygonal top then with sleeve in polygonal hole match.
The beneficial effect of the utility model: this sleeve is the multi-form tie down screw of dismounting easily, and is more convenient to operate, simple, can improve the operating efficiency of assembling, and reduced because of tie down screw and do not tightened the security incident that produces landing.

Fig. 3 is used for the cutaway view of the tie down screw on shaft-like top for the utility model.
Fig. 4 is used for the cutaway view of the tie down screw on hexagonal top for the utility model.
Fig. 5 is the sketch map of the tie down screw on existing shaft-like top.
Fig. 6 is the sketch map of the tie down screw on existing hexagonal top.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in Figure 2; One end of sleeve has the connecting rod 3 that cooperates with pneumtic impact wrench; The other end of sleeve has the hole slot that cooperates with the top of tie down screw, and this hole slot is made up of a hexagonal hole 2 and a bar-shaped trough 1, and hexagonal hole 2 is positioned at the axial center of sleeve; Bar-shaped trough 1 radially connects with hexagonal hole 2, and is symmetrical centre with the center of hexagonal hole 2.The shape size and the end shape size with the tie down screw on hexagonal top of hexagonal hole 2 adapt, and the shape size and the end shape size with the tie down screw on shaft-like top of bar-shaped trough 1 adapt.
Concrete method for using such as Fig. 3 and shown in Figure 4; Through the connecting rod on the sleeve 3 sleeve is installed on the aerofoil machine earlier; Again with jacket casing on the tie down screw top, if the tie down screw 5 on hexagonal top shown in Figure 6, the hexagonal top then with sleeve in hexagonal hole 2 match; If the tie down screw 4 on shaft-like top shown in Figure 5, then match with bar-shaped trough 1 in shaft-like top; After both overlap well, pull rifle along clockwise starting wind again tie down screw is tightened, take out wind at last and pull rifle.
