[0002] The hexagonal wrench is a common wrench tool, which is used to rotate a hexagonal bolt with a hexagonal groove in the center of the bolt head. It is often used for assembly and disassembly between workpieces. The existing hexagonal wrench has an "L"-shaped structure with a fixed length. Usually, the shorter end is used to cooperate with the hexagonal bolt, and the operator holds the longer end for easy operation. However, the traditional hexagonal wrench is an integrated overall structure and is divided into multiple pieces due to different sizes. After use, it is often lost when stored, resulting in incomplete wrench sizes. Its length is fixed, and the larger hexagonal wrench occupies a larger space, which is inconvenient for the operator to carry.

[0025] like Figures 1 to 5 As shown, a specific embodiment of the present invention provides a new foldable wrench, including a first handle body 1, the first handle body 1 and the second handle body 2 are slidingly arranged, the second handle body 2 is arranged in an L shape, one end of the second handle body 2 is arranged inside the first handle body 1, and the other end of the second handle body 2 is arranged outside one end of the first handle body 1 and is installed with a wrench head 4, the other end of the first handle body 1 is provided with a handle base 11, the upper end of the handle base 11 is provided with a screw rod 8, the screw rod 8 is threadedly connected to one end of the second handle body 2, and a storage cavity 14 is provided inside the handle base 11.

[0026] By adopting the above technical solution, the utility model is designed with a mounting hole 3, and a wrench head 4 of corresponding size can be selected according to different usage conditions and installed inside the mounting hole 3, so that the wrench can remove hexagon socket screws of various sizes. By providing a storage cavity 14 inside the handle seat 11, the wrench head 4 after use is stored inside the storage cavity 14 to avoid loss. By designing the second handle body 2, the second handle body 2 can be extended or retracted from the inside of the first handle body 1 to adjust the overall length of the wrench. During the use of the wrench, it can be adjusted to a suitable length to save effort, and it can be folded and retracted into the inside of the first handle body 1 after use. It has the advantages of both length and the volume of the wrench can be reasonably set.

[0027] Specifically, such as Figure 2 and Figure 5 As shown, a protrusion 5 is fixedly provided at one end of the wrench head 4, and the protrusion 5 is arranged inside the mounting hole 3. The protrusion 5 is arranged in a hexagonal shape, and the protrusion 5 is magnetic. The wrench head 4 and the protrusion 5 are arranged in several groups, and the sizes of the wrench head 4 are different. The sizes of the protrusion 5 are all adapted to the size of the mounting hole 3. The wrench head 4 and the protrusion 5 are arranged inside the storage cavity 14.

[0028] By adopting the above technical solution, the sizes of the wrench heads 4 are all different and a protrusion 5 of the same size is fixed at one end. The protrusion 5 is inserted into the inside of the mounting hole 3, which facilitates the quick installation of the wrench head 4 and the second handle body 2. The protrusion 5 is set to be hexagonal to prevent the protrusion 5 from rotating inside the mounting hole 3 during the process of changing hands. The protrusion 5 is magnetic and can be adsorbed with the second handle body 2 to prevent loosening and falling off after installation.

[0029] Specifically, such as Figure 2 As shown, a sealing cover 15 is provided at one end opening of the storage cavity 14 , and the sealing cover 15 is threadedly connected to one end of the handle base 11 .

[0030] By adopting the above technical solution, the sealing cover 15 is installed at one end of the handle base 11 in a rotational manner to seal the storage cavity 14, so as to better store the wrench head 4 stored inside the storage cavity 14. The sealing cover 15 is separated from the handle base 11 by reverse rotation to facilitate the removal of the wrench head 4 and to install it on the second handle body 2 for use.

[0031] Specifically, such as Figure 2 As shown, a through hole 6 is provided inside the first handle body 1 , and the through hole 6 is provided through both ends of the first handle body 1 . The size of the through hole 6 is adapted to the second handle body 2 and is slidably provided with the second handle body 2 .

[0032] By adopting the above technical solution and providing the through hole 6 inside the first handle body 1 , the second handle body 2 can be extended from and retracted into the first handle body 1 to adjust the length of the wrench.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, a slider 9 is fixedly provided at one end of the second handle body 2. The size of the slider 9 is adapted to the slide groove 10. The slider 9 is slidably arranged inside the slide groove 10. The slide groove 10 is arranged inside the first handle body 1. The length of the slide groove 10 is set to two-thirds of the length of the first handle body 1.

[0034] By adopting the above technical solution, by setting the slider 9 and the slide groove 10, the extension length of the second handle body 2 is limited while preventing the second handle body 2 from rotating inside the first handle body 1. The length of the slide groove 10 is two-thirds of the length of the first handle body 1, so that the second handle body 2 has sufficient length inside the first handle body 1 after being extended, avoiding the situation where the second handle body 2 is broken and separated from the first handle body 1 during the process of applying force when the connection part is short after the second handle body 2 is extended from the inside of the first handle body 1.

[0035] Specifically, such as Figure 2 As shown, a countersunk hole 7 is provided inside the second handle body 2 , a screw rod 8 is provided inside the countersunk hole 7 , and a thread is partially provided at one end of the countersunk hole 7 , which is adapted to the screw rod 8 .

[0036] By adopting the above technical solution, one end of the countersunk hole 7 is provided with a thread and is threadedly connected to the screw rod 8 , and the extension length of the second handle body 2 can be adjusted by rotating the screw rod 8 .

[0037] Specifically, such as Figure 2 and Figure 4 As shown, a convex ring 12 is provided at one end of the handle seat 11, and the convex ring 12 is rotatably provided inside the annular groove 13. The annular groove 13 is provided at one end of the first handle body 1, and a plurality of grooves 16 are provided on the outer side of the first handle body 1.

[0038] By adopting the above technical solution, the convex ring 12 is connected with the annular groove 13 so that the handle base 11 is installed as a whole with the first handle body 1 and can rotate with the first handle body 1, which is convenient for adjusting the extension length of the second handle body 2. A plurality of grooves 16 are provided on the outside of the first handle body 1, so that the friction between the first handle body 1 and the palm is increased during the use of the wrench. At the same time, air can circulate inside the grooves 16, thereby enhancing breathability and reducing sweating of the palms.
