Description

Anti-theft screw removal sleeve

This creation relates to a sleeve, and more particularly to a sleeve for removing an anti-theft screw.

In general, in order to prevent theft of tires, advanced imported cars often have anti-theft screws on the wheel frame. By using anti-theft screws that are difficult to disassemble with general tools, the chances of being thieves are reduced, and the general anti-theft screws are often hidden in the car. In a recessed hole, the tool is difficult to reach, and often has a strangely shaped head, which makes the general tool difficult to fit.

However, there is still a need to remove the anti-theft screws when repairing or replacing the tires. Therefore, special removal tools are required for removal. For example, the patents TW M495926 and CN 206550931U are used to match the head with a special shape. The screw is sleeved on the head of the anti-theft screw with a corresponding shape of the sleeve inside the sleeve, and the sleeve can be rotated by the driving tool to screw the anti-theft screw; Patent TW M425747 discloses another form of dismantling The inner diameter of the sleeve is tapered inward, and the head of the anti-theft screw can be snap-fitted into the sleeve hole by tapping the tool, and the anti-theft screw can be driven by rotating the sleeve with the driving tool. The advantage of turning is that it can be matched with different shapes of anti-theft screw heads.

However, the patents TW M495926 and CN 206550931U are only suitable for the special anti-theft screws of the head shape, especially the anti-theft screws for the round head can not be removed at all; as for the patent TW M425747, although it can match the anti-theft screws of different shapes, the sleeve In order to extend the long rod-shaped tool into the long rod-like tool after use, the tube is ejected from the anti-theft screw, and the whole body is hollow, which is difficult to withstand the torsion and is easy to be broken, and the sleeves of different sizes of the sleeve holes must be separately manufactured, and the cost is high.

The main purpose of this creation is to provide an anti-theft screw removal sleeve that saves manufacturing costs and is easy to manufacture and use.

In order to achieve the above object, the present invention provides an anti-theft screw dismounting sleeve comprising a body and a driving head.

The body has a first end and a second end, the body has a set of holes at the first end, and the body has a first connecting portion at the second end, wherein the inner diameter of the sleeve is The first end is tapered toward the second end; the driving head has a third end and a fourth end, and the driving head has a second connecting portion at the third end, the driving head is at the The four ends have a driving portion, and the second connecting portion is detachably and non-rotatably connected to the first connecting portion. When the first connecting portion is connected to the second connecting portion, the body and the driving head cannot be wound An axially opposite rotation, the drive portion is coupled to a drive tool to drive the drive head to rotate.

Thereby, the creation can be used with the same driving head with different sizes of the body, and has good structural strength, and is convenient for taking out the anti-theft screw.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIG. 1 to FIG. 5 , the present invention provides an anti-theft screw disassembling sleeve comprising a body 10 and a driving head 20 .

The body 10 has a first end 11 and a second end 12 . The body 10 has a set of holes 13 at the first end 11 . The body 10 has a first connecting portion 14 at the second end 12 . The inner diameter of the sleeve hole 13 is tapered from the first end 11 toward the second end 12; the driving head 20 has a third end 21 and a fourth end 22 (preferably, the body) The driving head 20 has a second connecting portion 23 at the third end 21, and the driving head 20 has a driving portion 24 at the fourth end 22, the second connection The portion 23 is detachably and non-rotatably connected to the first connecting portion 14. When the first connecting portion 14 is connected to the second connecting portion 23, the body 10 and the driving head 20 cannot rotate relative to each other in an axial direction. The driving portion 24 is connected by a driving tool 60 to drive the driving head 20 to rotate.

In the embodiment, the first connecting portion 14 is a polygonal hole (for example, a quadrangular hole, a hexagonal hole, an octagonal hole, etc.), and the second connecting portion 23 is a polygonal column (for example, a quadrangular column, a hexagonal column, and an octagonal column). And the plurality of corner holes correspond to each other, and the driving portion 24 is also a polygonal column (for example, a quadrangular column, a hexagonal column, an octagonal column or the like can be matched with a tool such as a wrench), and the maximum inner diameter of the first connecting portion 14 is smaller than The minimum inner diameter of the sleeve hole 13 forms a class surface between the first connecting portion 14 and the sleeve hole 13 , and the driving portion 24 and the second connecting portion 23 have a larger outer diameter. In addition, preferably, the end of the third end 21 of the driving head 20 is sleeved with a C-shaped ring 26, and the minimum outer diameter of the C-ring 26 is larger than the maximum outer diameter of the second connecting portion 23, thereby The C-ring 26 has elasticity to abut against the inner wall of the first connecting portion 14, so that the driving head 20 is substantially positioned on the body 10.

In addition, the fourth end 22 of the driving head 20 is further recessed with a receiving hole 25 extending along the axial direction of the driving head 20 and not extending to the second connecting portion 23, the receiving hole 25 An auxiliary tool 40 is extended into the top for a tapping tool 50 to strike.

In actual use, the appropriate body 10 is selected (depending on the type, size, and shape of the anti-theft screw to be disassembled), the body 10 and the driving head 20 are connected to each other, and the body 10 is inserted into the anti-theft screw 30. The recessed hole 70 (generally, the head 31 of the anti-theft screw 30 is located at the bottom of the recessed hole 70 to prevent any tool from being removed), so that the head 31 of the anti-theft screw 30 extends into the sleeve hole 13 And an auxiliary tool 40 (preferably a bar-shaped tool) is inserted into the receiving hole 25, and the other end of the auxiliary tool 40 is tapped by a tapping tool 50 (for example, a hammer) to make the body 10 is tightened in the direction of the anti-theft screw 30. Since the sleeve hole 13 is tapered inwardly, the head 31 of the anti-theft screw 30 can be clamped and positioned by the body 10 by the above-mentioned tapping. As shown in FIG. 3, a driving tool 60 (for example, a wrench) can be coupled to the driving portion 24 to rotate the driving head 20. The driving head 20 further drives the body 10 to rotate, and the body 10 is further driven. The head 31 of the anti-theft screw 30 is rotated, and the anti-theft screw 30 can be turned outward. It will be removed, as shown in FIG.

As for how the anti-theft screw that has been removed is removed from the main body, as shown in FIG. 5, the driving head 20 is first removed from the main body 10, and the main body 10 is clamped and fixed by a clamping tool 80, and then A removal tool 90 (preferably a bar-shaped tool) extends from the first connecting portion 14 into the body 10 and further extends into the sleeve hole 13 to abut the head 31 of the anti-theft screw 30. The anti-theft screw 30 can then be knocked out by tapping the other end of the removal tool 90 with the tapping tool 50. The anti-theft screw of the present invention is used for disassembling the sleeve, and the body 10 and the driving head 20 are separately designed. For the anti-theft screw after unscrewing, the complete structure of FIG. 5 or the anti-theft screw head and the smaller diameter are presented. When the screw segment is in a broken state, it can be separated from the body through the driving head, and the function of removing the tool to knock out the body sleeve hole is supplemented by the removal tool.

With the above structure, the anti-theft screw disassembling sleeve provided by the present invention can match different types of bodies with the same driving head, which can reduce the manufacturing cost, and the driving head can be non-through, increase the structural strength, and can withstand the torsion and avoid The breakage is damaged. In addition, the drive head and the body can also be made of different materials to meet the function requirements.
