Description

Technical Field

[0001] This invention relates to hand tools, and more particularly to a tool connector. Background Technology

[0002] When tightening or loosening screws, nuts, bolts, or other fasteners, power tools, pneumatic tools, or hand tools are often used with sockets or other adapters. Because different fasteners have different specifications, types, and operating environments, users usually need to use tool adapters as a medium to allow the rotating tool to quickly connect to different sizes of fasteners, thereby improving the tool's applicability and ease of use.

[0003] However, conventional tool joints are prone to loosening, jamming, or detachment when subjected to repeated loading and unloading of fasteners or high-speed rotation, vibration, and impact from rotating tools due to inaccurate positioning or uneven operation. This not only affects tool change efficiency but may also reduce operational stability and safety. Furthermore, insufficient precision in the fit of the internal components of the tool joint or uneven stress can easily lead to increased wear and affect its service life, making improvement necessary.

[0004] Therefore, it is necessary to provide a novel and progressive tool connector to solve the above-mentioned problems. Summary of the Invention

[0023] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection, as will be stated in advance.

[0024] Please refer to Figures 1 to 6 This illustrates an embodiment of the present invention, in which the tool connector comprises: a body 1, a stop member 4, a control member 5, an elastic member 6, and a locking mechanism 7.

[0025] The body 1 defines an axial direction 11 and a radial direction 12. The abutment 4 is movably disposed on the body 1 along the radial direction 12. The control member 5 includes a locking section 51, which includes at least one slot 52 and at least one corner portion 53. The at least one slot 52 extends along the axial direction 11 and the at least one corner portion 53. The control member 5 is movable along the axial direction 11 to be inserted into the body 1 in a locked position and a released position. When the control member 5 is in the locked position, it pushes against the abutment 4 along the radial direction 12, and the abutment 4 protrudes from the body 1. When the control member 5 is in the released position, it does not push against the abutment 4, and the abutment 4 can retract into the body 1 along the radial direction 12. The elastic member 6 springs against the body 1 and the control member 5 to give the control member 5 a tendency to move toward the locked position.

[0026] The displacement of the control element 5 along the axial direction 11 can be converted into the extension and retraction of the abutment 4 in the radial direction 12. The user only needs to push the control element 5 to complete the installation and removal of the sleeve, which is quite convenient and quick to use. In addition, the elastic element 6 can return the control element 5 to the locked position in its normal state, so as to reduce the possibility of accidental loosening during use.

[0027] The locking mechanism 7 includes at least one through groove 71 and a locking member 72. The at least one through groove 71 is disposed in the body 1 and corresponds to at least one locking slot 52 in the radial direction 12. The locking member 72 is clamped to the body 1. A portion of the locking member 72 extends into the at least one locking slot 52 along the radial direction 12 through the at least one through groove 71. Thus, the locking member 72 blocks the control member 5 in the axial direction 11, preventing the control member 5 from detaching from the body 1. The locking member 72 extends into the at least one locking slot 52 from the outside along the radial direction 12, which has the advantages of simple assembly, clear positioning, and easy maintenance and replacement.

[0028] It is worth mentioning that at least one slot 52 is provided at at least one corner 53, so that the at least one slot 52 can provide the insertion space for the locking member 72 by utilizing the corner 53 position of the locking section 51, ensuring that the planar side of the locking section 51 can still maintain the guiding relationship of surface contact with the corresponding hole wall of the body 1, and the control member 5 can be displaced along the axial direction 11 while maintaining better anti-rotation, coaxial guidance and stable force transmission. In this embodiment, the cross-sectional profile of the locking section 51 is polygonal, the locking section 51 is a hexagonal rod, the at least one corner 53 includes a plurality of corners 53, the at least one slot 52 includes a plurality of slots 52, and the plurality of slots 52 are distributed at the plurality of corners 53.

[0029] Along the axial direction 11, the length of each slot 52 is greater than the length of each through slot 71, ensuring that when the control member 5 moves between the locked position and the released position, the locking member 72 can remain in each slot 52 without interfering with the normal stroke of the control member 5, so that the control member 5 has the effect of being able to slide along the axial direction 11 without detaching from the body 1.

[0030] On the radial direction 12, the length of each through groove 71 is greater than the length of each slot 52. Thus, when viewed from the side, a portion of the locking section 51 will be exposed in at least one through groove 71, which makes it easy to confirm whether the locking member 72 is indeed inserted into the slot 52. At the same time, it can reduce the difficulty of alignment during assembly, thereby improving the assembly yield and locking reliability.

[0031] The main body 1 includes a first component 2 and a second component 3. The first component 2 includes a head 21 and a connecting part 22 connected together. At least one through groove 71 is provided in the connecting part 22. The locking member 72 is clamped in the connecting part 22. The second component 3 is sleeved on the connecting part 22 along the axial direction 11 to cover the locking member 72 and the at least one through groove 71. This can take into account both assembly convenience and protection, and can also prevent foreign objects from affecting the locking action.

[0032] Preferably, the inner side of the second component 3 is recessed along the radial direction 12 with at least one positioning recess 31. The locking member 72 further includes a clamping portion 721 and at least one positioning protrusion 722. The clamping portion 721 is clamped to the assembly portion 22, and the at least one positioning protrusion 722 protrudes from the clamping portion 721. When the second component 3 is sleeved on the assembly portion 22, the at least one positioning protrusion 722 is inserted into the at least one positioning recess 31, so that the second component 3 cannot be disengaged from the first component 2. In this way, the locking member 72 can not only block the control member 5, but also prevent the second component 3 from disengaging from the first component 2 through the engagement of the at least one positioning protrusion 722 and the at least one positioning recess 31. Thus, the locking member 72 has the dual functions of preventing the control member 5 from disengaging and positioning the second component 3, thereby reducing the number of parts and improving the overall structural integration.

[0033] In this embodiment, there are three of the at least one positioning recess 31 and three of the at least one positioning protrusion 722. Through the three-point positioning configuration, a more stable clamping and positioning effect can be formed between the second component 3 and the first component 2, avoiding the second component 3 from swaying or loosening relative to the first component 2. In this embodiment, when viewed along the axial direction 11, one positioning recess 31 and two positioning recesses 31 are arranged opposite to each other.

[0034] The second component 3 has a through hole 32 extending along the axial direction 11. When the second component 3 is sleeved on the assembly part 22, the control component 5 protrudes from the second component 3 through the through hole 32, and the user can directly operate the control component 5 from the outside. The outline of the through hole 32 matches the outline of the locking section 51, which can provide a guiding and anti-sway effect for the control component 5, making the movement of the control component 5 along the axial direction 11 more stable and reducing the possibility of jamming during operation.

[0035] Preferably, the outer surface of the second component 3 is provided with a textured anti-slip structure 33, which can increase the friction between the user's hand and the second component 3, allowing the user to hold and operate stably, thereby improving operational safety.

[0036] The head 21 includes a first section 211 and a second section 212. The abutment 4 is disposed in the first section 211. The outer contour of the second section 212 is circular. The outer diameter of the second section 212 is larger than the maximum outer diameter of the first section 211. When the second component 3 is sleeved on the assembly part 22, the outer diameter of the side of the second component 3 near the head 21 is equal to the outer diameter of the second section 212. This makes the appearance and stress contour of the head 21 and the second component 3 more continuous, reducing collisions, scratches or stress concentration caused by step differences, and improving the overall structural strength and grip feel.

[0037] The control component 5 further includes a working section 54 and a connecting rod 55. The locking section 51 is connected between the working section 54 and the connecting rod 55. The working section 54 includes a receiving portion 541 and a sloped portion 542 arranged adjacent to each other along the axial direction 11. When the control component 5 is in the locked position, the sloped portion 542 pushes against the abutment 4. The sloped portion 542 can convert the pushing of the control component 5 along the axial direction 11 into the outward pushing of the abutment 4 along the radial direction 12, so that the locking action is smooth and effortless. When the control component 5 is in the released position, the receiving portion 541 can receive and accommodate the portion of the abutment 4, so that the abutment 4 has enough space to retract into the body 1, so as to facilitate quick disassembly of the sleeve.

[0038] Preferably, the working section 54, the locking section 51, and the connecting rod 55 are integrally formed, which can improve the structural strength, transmission stability, and durability of the control component 5; at the same time, it can also reduce assembly steps, reduce assembly errors, and improve mass production consistency.

[0039] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
