Description

Technical Field

[0001] The invention relates to an adjustable spanner, belonging to the field of hardware tools, and is particularly characterized in that a socket is adopted to adjust the spanner width of the spanner. Background Art

[0002] The wrench is a commonly used work tool. There are many types of wrenches, which can be divided into two types according to their adjustability: adjustable wrenches and fixed wrenches. They each have their own advantages and disadvantages.

[0003] 1. Advantages and disadvantages of existing fixed wrenches

[0004] The fixed spanner does not need to adjust the width of the spanner when working. The spanner and the nut have a high degree of fit, and the clamping is more secure, basically seamless. It will not slip and will not damage the screw. It can work quickly, and the working speed is faster than the adjustable spanner. It has a long service life and is not easy to damage. The manufacturing process is simple, the cost is low, and the price is low. It is relatively small and light, and is more suitable for narrow working environments.

[0005] The disadvantages of fixed wrenches come from the design itself. Currently, fixed wrenches basically adopt a double-head design, that is, a fixed wrench can screw nuts of two specifications. However, there are many types of nuts at present. Therefore, it is necessary to carry multiple wrenches when working, and it is troublesome to frequently change wrenches of different sizes. It is necessary to manage multiple wrenches at the same time to prevent loss. It is very troublesome. There is also a head-changing fixed wrench on the market, which uses the head-changing method to adjust the width of the wrench mouth, but it also needs to be equipped with multiple wrench heads for replacement, and it is necessary to manage multiple wrench heads at the same time to prevent loss, which is also troublesome.

[0006] 2. Advantages and disadvantages of existing adjustable wrenches.

[0007] Today's adjustable wrenches can adapt to a variety of nuts of different sizes because their opening width is continuously adjustable. There is no need to frequently change different wrenches when using them, which is its advantage. But its disadvantages are also obvious. And again: the fatal disadvantage comes from the design itself. First, it is easy to slip. When the nut that needs to be rotated is tight and the force is slightly greater, the movable lip of the adjustable wrench is easily expanded to cause displacement and slip. This is because the opening adjustment direction of the adjustable wrench is consistent with its force direction. Even if the opening width after adjustment is consistent with the size of the nut, when force is applied, there will be a gap between the adjusting wheel and the rack. After the adjustable wrench is used for a long time, there will be a gap due to wear, which will cause the opening of the wrench to swell, resulting in slipping, and the nut can be rounded in one second, thereby damaging the nut. Second, due to the setting of the adjustment mechanism, the manufacturing cost and manufacturing difficulty increase accordingly, resulting in a higher price. Summary of the invention

[0008] The technical problem to be solved by the present invention is to combine the advantages of an adjustable wrench and a fixed wrench and eliminate their disadvantages. The fixed wrench should have the advantages of being difficult to slip and having a high degree of fit with the nut, and should also be able to adapt to nuts of all sizes.

[0009] In order to solve the above problem, the present invention adopts a socket method to adjust the size of the spanner. Since the size of the spanner is adjusted by the socket method, the spanner will not become larger due to force during use. In this way, the spanner has the advantages of a fixed spanner that is not easy to slip and has a high degree of fit with the nut, and also has the advantages of an adjustable spanner that can adapt to various nut models.

[0045] The technical problem to be solved by the present invention is to combine the advantages of adjustable wrenches and fixed wrenches and discard their disadvantages. It should have the non-slip advantage of a fixed wrench and be able to adapt to both large and small nuts, that is, one wrench can handle all types.

[0046] To solve the above problems, the present invention uses a socket method to adjust the size of the wrench opening. Since the socket method is used to adjust the size of the wrench opening, the wrench opening will not become larger due to the force during use. In this way, the wrench has both the non-slip advantage of a fixed wrench and the advantage of an adjustable wrench that can adapt to various nut models.

[0047] The first wrench of the present invention includes a handle 1, a wrench head 2, and a plug-in 4. The wrench head 2 further includes a fixed wrench lip 3 and an insertion rail 15. The fixed wrench lip 3 and the insertion rail 15 are integrated. The wrench can be in the normal form of a currently commercially available adjustable wrench or in the form of an F wrench, such as Figure 1 . The insertion rail 15 is connected to the wrench head 2 and is a part of the wrench head 2, and is also connected to the handle 1 at the same time. The insertion rail 15 is characterized in that its cross-sectional shape is in the shape of a Feng character (like a crenelated wall); there are teeth 16 on two surfaces of the insertion rail 15, and both the tooth width and the tooth pitch are 2 mm. Such as Figure 2 . The plug-in 4 is rectangular when viewed from the front and in the shape of the letter H when viewed from the side, such as Figure 3 . There are two insertion feet 7 at both ends of the plug-in 4. The two insertion feet 7 are arranged in a two-character shape, and there are teeth 16 in the middle. Both the tooth width and the tooth pitch are 2 mm, and the tooth shape is arranged in the shape of a crenelated wall, such as Figure 4 . Marks for facilitating the adjustment of the width of the wrench opening are engraved on the plug-in. Each time the insertion direction of the plug-in 4 is changed, the width of the wrench opening can be adjusted by 1 mm. The plug-in 4 has four directions and can adjust the width of the wrench opening by 4 mm. For a larger width of the wrench opening, it needs to be adjusted by changing the insertion position of the plug-in 4, and each time the insertion position is changed, it is adjusted by 4 mm. In this way, the width of the entire wrench opening can be continuously adjusted at 1-mm intervals.
