[0018] This embodiment utilizes the cooperation between the ratchet 22 and the pawl 23 so that the socket assembly 40 can be reversibly unidirectionally driven by the handle 10. The cooperation between the socket assembly 40 and the ratchet 22 allows the position of each socket 42 to be flexibly changed. It integrates the advantages of the wide range of applications of the socket wrench and the reversible unidirectional drive of the ratchet wrench, so that the handle can reversibly unidirectionally drive the threaded component to rotate at the desired position.

[0019] In this embodiment, the handle 10 and the wrench head 20 are an integrally formed structure, and the interior of the assembly groove 21 is provided with a first groove portion 211 for accommodating the ratchet 22, and a second groove portion 212 for accommodating the pawl 23, and the first groove portion 211 and the second groove portion 212 are both constructed in a circular shape, the axis of the first groove portion 211 is parallel to the axis of the second groove portion 212, and the first groove portion 211 is connected to the second groove portion 212, and the cover plate 30 covers the top of the assembly groove 21 and is fixed by screws, and a through hole 213 is provided in the first groove portion 211 and the cover plate 30, and the through hole 213 is coaxially arranged with the first groove portion 211, so that after the cover plate 30 is installed, a hollow installation space is formed at the position corresponding to the first groove portion 211 on the wrench head 20, and the sleeve assembly 40 rotates in the installation space.

[0020] It should be noted that the diameter of the first groove portion 211 is greater than the diameter of the second groove portion 212 , and the second groove portion 212 is arranged at an end portion close to the handle 10 .

[0021] In this embodiment, the ratchet 22 is constructed in a circular ring shape, the teeth of the ratchet 22 are arranged on the outer circumferential surface of the circular ring, the assembly hole 221 is formed on the ratchet 22 and is coaxially arranged with the ratchet 22, the ratchet 22 is rotatably arranged as a whole in the first groove portion 211, and the ratchet 22 is coaxially arranged with the first groove portion 211, the assembly hole 221 is coaxial with the through hole 213, and the diameters of the two are the same, and two connecting cylinders 222 for accommodating the rotating shaft 41 of the sleeve assembly 40 are provided on the side wall of the assembly hole 221, the two connecting cylinders 222 are coaxially arranged, and the axis of the connecting cylinder 222 is arranged along the radial direction of the assembly hole 221, that is, the two connecting cylinders 222 are arranged as a whole on the diameter of the assembly hole 221, and the two connecting cylinders 222 are symmetrically arranged.

[0022] In this embodiment, the pawl 23 is constructed as a whole into an arc-shaped sector, and the two ends of the sector form a clamping portion 231 that engages with the ratchet 22. Two arc-shaped limiting grooves 232 are provided on the circumferential surface of the sector. The limiting grooves 232 correspond to the clamping portion 231 one by one. The pawl 23 is rotatably arranged in the second groove portion 212 as a whole, and the pawl 23 and the second groove portion 212 are coaxially arranged. A lever 233 is fixedly connected to the axis of the pawl 23. After the lever 233 passes through the cover plate 30, it extends radially along the cover plate 30. Rotating the lever 233 can drive the pawl 23 to rotate, thereby changing the clamping state of the clamping portion 231 and the ratchet 22.

[0023] In addition, an insertion hole 214 is provided on the side wall of the second groove portion 212, and a push rod 24 is inserted in the insertion hole 214. A compression spring 241 is provided between the inner end of the push rod 24 and the bottom of the insertion hole 214, and the outer end of the push rod 24 abuts against the limiting groove 232. The limiting groove 232 is an arc-shaped groove concave toward the axis of the pawl 23. The compression spring 241 pushes the push rod 24 to move outward, so that the outer end of the push rod 24 abuts against the limiting groove 232. Accordingly, one of the clamping portions 231 of the pawl 23 is kept engaged with the teeth of the ratchet 22, and the other clamping portion 231 is away from the ratchet 22. When the lever 233 is swung, the ratchet 23 will be driven to rotate as a whole, so that the other limiting groove 232 can be rotated to a position corresponding to the push rod 24. At this time, the other clamping portion 231 will approach and be engaged with the ratchet 22, thereby changing the direction in which the ratchet 22 is driven.

[0024] In this embodiment, the sleeve assembly 40 includes a rotating shaft 41 and a plurality of sleeves 42. The rotating shaft 41 and the plurality of sleeves 42 are an integrally formed structure. The rotating shaft 41 can be rotatably inserted into the interior of the connecting cylinder 222, so that the rotating shaft 41 is arranged as a whole along the diameter direction of the ratchet 22. The plurality of sleeves 42 are all constructed in a cylindrical shape, and the plurality of sleeves 42 have inner holes for adapting to different types of threaded components (such as bolts, screws, and nuts). The plurality of sleeves 42 are distributed at intervals along the circumference of the rotating shaft 41, and the axes of the plurality of sleeves 42 intersect at the intersection of the axes of the rotating shaft 41 and the assembly hole 221, so that after the handle 10 is rotated around the rotating shaft 41 to the desired position, the sleeve that clamps the threaded component can be reversibly driven to rotate in one direction.
