The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the socket wrench 100 in the first embodiment; Figure 2 for Figure 1 A schematic diagram of the socket wrench 100 from another angle; Figure 3 for Figure 1 An exploded schematic diagram of the socket wrench 100 shown.

[0041] This invention provides a socket wrench 100, a hardware tool for tightening threaded parts in narrow or recessed locations. In this embodiment, the socket wrench 100 is used to tighten bolts and nuts. It is understood that in other embodiments, the socket wrench 100 can also be used to tighten other hardware parts.

[0042] Traditional socket wrenches are only suitable for one type of threaded part. To accommodate different threaded parts, socket wrenches are usually sold in sets containing multiple sizes. However, selling socket wrenches in sets not only wastes manufacturing materials but also takes up storage and transportation space, increasing transportation costs and making them inconvenient for users to store.

[0043] Based on this, this application provides a socket wrench 100, including a main body 10, an adjusting ring 20, a driving ring 30, and at least two inner diameter adjusting members 40. The main body 10 includes a wrench engagement portion 11 and a size adjusting portion 12 that are disposed opposite to each other. The adjusting ring 20 and the driving ring 30 are both sleeved on the main body 10. The at least two inner diameter adjusting members 40 cooperate with each other and are used to clamp threaded parts. The main body 10, the adjusting ring 20, the driving ring 30, and the inner diameter adjusting members 40 cooperate with each other to adjust the inner diameter of the pattern formed by the at least two inner diameter adjusting members 40.

[0044] The present disclosure will now be described through several specific embodiments. To keep the following description of the embodiments of the invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the invention appears in more than one drawing, the component may be represented by the same or similar reference numerals in each drawing.

[0045] Example 1

[0046] The outer peripheral walls of both the wrench engagement portion 11 and the size adjustment portion 12 of the main body 10 are approximately cylindrical, and the outer diameter of the size adjustment portion 12 is larger than that of the wrench engagement portion 11. The wrench engagement portion 11 has a wrench engagement port 111 for engaging with external hand tools or power tools; the size adjustment portion 12 has a nut engagement port 121 for engaging with the inner diameter adjustment member 40; the peripheral wall of the size adjustment portion 12 also has an opening groove 13 for mounting the inner diameter adjustment member 40.

[0047] The wrench engagement 111 is preferably a square prism-shaped hole, and the nut engagement 121 is preferably a regular hexagonal prism-shaped hole. It is understood that the wrench engagement 111 or the nut engagement 121 can also be other shapes, as long as they can be used to engage with external tools or nut heads.

[0048] The outer peripheral wall of the adjusting ring 20 is approximately cylindrical. The adjusting ring 20 is fitted with the size adjusting part 12 of the main body 10, and the inner wall of the adjusting ring 20 has at least two adjusting grooves 221. The two adjusting grooves 221 have different depths along the radial direction of the adjusting ring 20. The adjusting ring 20 and the main body 10 are fixed relative to each other in the axial direction, and the adjusting ring 20 can rotate relative to the main body 10 in the circumferential direction. The adjusting grooves 221 can be aligned with the opening grooves 13 and joined together to form receiving grooves (not labeled). The receiving grooves are used to accommodate the inner diameter adjusting part 40. By joining the opening grooves 13 with different adjusting grooves 221, receiving grooves of different depths can be formed. By cooperating with the inner diameter adjusting part 40 and receiving grooves of different sizes, nuts of different sizes can be fixed.

[0049] The drive ring 30 is generally cylindrical and is sleeved on the adjusting ring 20, allowing it to slide along the axis of the adjusting ring 20. A connector 31 protrudes from the inner wall of the drive ring 30 for connecting the inner diameter adjusting member 40. The connector 31 drives the inner diameter adjusting member 40 to slide back and forth along the axis of the adjusting ring 20. Preferably, the outer wall of the drive ring 30 is also provided with anti-slip textures (not labeled).

[0050] There are at least two inner diameter adjusting members 40, which cooperate with each other and are used to clamp the threaded parts. Each inner diameter adjusting member 40 is elongated, with one end accommodated in the receiving groove formed by the adjustment groove 221 and the opening groove 13, and the other end connected to the connector 31. The inner diameter adjusting member 40 can move along the axial direction of the adjustment ring 20 towards the side relatively close to the wrench engagement 11 under the drive of the connector 31. After rotating the adjustment ring 20, the opening groove 13 is aligned with another adjustment groove 221 of different depth and assembled to form receiving grooves of different sizes. The inner diameter adjusting member 40 can be accommodated in receiving grooves of different sizes to adjust the inner diameter of the pattern formed by the at least two inner diameter adjusting members 40.

[0051] Please refer to the following: Figures 4 to 9 , Figure 4 for Figure 1 The shown is a cross-sectional view of the socket wrench 100 in its first use state; Figure 5 for Figure 4 Top view of the socket wrench 100 shown; Figure 6 for Figure 1 The shown is a cross-sectional view of the socket wrench 100 when it is transitioning from a first use state to a second use state. Figure 7 for Figure 6 Top view of the socket wrench 100 shown; Figure 8 for Figure 1 The socket wrench 100 shown is a cross-sectional view in its second use state; Figure 9 for Figure 8 The top view of the socket wrench 100 shown. Wherein, Figure 6 and Figure 7 The arrow in the image indicates the direction of movement of the drive ring 30.

[0052] In one embodiment, the socket wrench 100 further includes a pushing assembly 50 connected to the inner diameter adjusting member 40. The pushing assembly 50 is capable of moving the inner diameter adjusting member 40 towards the end relatively away from the wrench engagement portion 11, causing the inner diameter adjusting member 40 to extend into receiving grooves of different sizes. It is understood that in other embodiments, the pushing assembly 50 may not be provided, and the inner diameter adjusting member 40 may be extended into the adjusting groove 221 by manually pushing the drive ring 30, or by other common methods.

[0053] The process of using socket wrench 100 is as follows: Figure 4Using the indicated direction as a reference, the user pushes the drive ring 30 downwards. The connector 31 in the drive ring 30 causes the inner diameter adjusting member 40 to move downwards as well, until the inner diameter adjusting member 40 disengages from the adjusting groove 221. At this point, the adjusting ring 20 is rotated until the opening groove 13 aligns and engages with another adjusting groove 221 of different depths. Under the drive of the pushing component 50, the inner diameter adjusting member 40 extends into receiving grooves of different sizes, thus changing the inner diameter of the pattern formed by the inner diameter adjusting member 40, thereby enabling the clamping of threaded parts of different types. Figure 5 and Figure 9 As shown, Figure 5 In the middle, the inner diameter adjusting component 40 is located in a relatively deep adjusting groove 221. The inner diameter of the shape formed by the inner diameter adjusting component 40 is relatively large, which allows the socket wrench 100 to actually connect to nuts of a larger size. Figure 5 The dimension indicated by the dashed line; when the dimension is changed, such as... Figure 9 As shown, at this time, the inner diameter adjusting component 40 is located in a shallow adjusting groove 221. The inner diameter of the shape formed by the inner diameter adjusting component 40 is small, which makes the actual size of the nut that the socket wrench 100 can connect to smaller. Figure 9 The dimensions are indicated by the dashed lines in the diagram.

[0054] It is understood that in other embodiments, the opening groove 13 can also be aligned with the adjustment grooves 221 of different depths by rotating the drive ring 30. At this time, the inner diameter adjustment member 40 can drive the main body 10 to rotate through the inner wall of the opening groove 13, so that the opening groove 13 is aligned with the adjustment grooves 221 of different depths, thereby changing the inner diameter size of the pattern formed by the inner diameter adjustment member 40.

[0055] In one embodiment, the opening groove 13 is opened along the axial direction of the body 10, thereby better accommodating the movement of the inner diameter adjustment member 40.

[0056] Since the heads of standard threaded parts are mostly hexagonal, in one embodiment, to better suit standard threaded parts, the nut engagement 121 is a hexagonal prism hole, and the number of opening slots 13 is preferably three. The number of inner diameter adjusting members 40 is the same as the number of opening slots 13. The three opening slots 13 are evenly distributed on the peripheral wall of the size adjustment part 12 and located at the center of the edge of the hexagonal prism hole, which can better accommodate various types of standard threaded parts. It is understood that in other embodiments, the nut engagement 121 can also be of other shapes, and the number of opening slots 13 and inner diameter adjusting members 40 can be one, two, or more, and the number of inner diameter adjusting members 40 can be less than the number of opening slots 13; as long as the inner diameter of the shape formed by the inner diameter adjusting members 40 can be adjusted.

[0057] To prevent axial displacement between the main body 10 and the adjusting ring 20, an axial limiting member 14 is protruding from the outer peripheral wall of the size adjustment part 12 of the main body 10; an axial limiting groove 21 is formed on the inner peripheral wall of the adjusting ring 20, and the axial limiting member 14 can slide in the axial limiting groove 21 to limit axial displacement when the main body 10 and the adjusting ring 20 rotate relative to each other. It can be understood that in other embodiments, the axial limiting groove 21 can also be formed on the outer peripheral wall of the size adjustment part 12 of the main body 10, and the axial limiting member 14 can be protruding from the inner peripheral wall of the adjusting ring 20, as long as it can prevent axial displacement between the main body 10 and the adjusting ring 20.

[0058] To allow for more flexible rotation between the main body 10 and the adjusting ring 20, the axial limiting groove 21 is preferably an annular groove, and there are three axial limiting members 14 evenly distributed on the peripheral wall of the size adjustment part 12, with the three axial limiting members 14 arranged in a concentric circle. It can be understood that in other embodiments, the axial limiting groove 21 may also be multiple concentric grooves, or may be of other shapes, as long as it allows the axial limiting members 14 to slide within the axial limiting groove 21.

[0059] To prevent the adjusting ring 20 from dislodging from the drive ring 30, the socket wrench 100 also includes a locking pin 15 and a first elastic element 16. The axial limiting member 14 has a locking groove 141, which accommodates part of the structure of the first elastic element 16 and the locking pin 15. One end of the first elastic element 16 abuts against the inner wall of the locking groove 141, and the other end abuts against the inner wall of the axial limiting groove 21 of the adjusting ring 20 via the locking pin 15. When the first elastic element 16 is in a compressed state, it can press the adjusting ring 20 tightly against the drive ring 30, preventing the adjusting ring 20 from dislodging from the drive ring 30. On the other hand, the locking pin 15 also prevents the axial limiting member 14 from directly contacting the axial limiting groove 21. The rotational movement between the main body 10 and the adjusting ring 20 can be achieved by sliding the locking pin 15 along the inner wall of the axial limiting groove 21, increasing the smoothness of the adjustment ring 20's rotation relative to the main body 10.

[0060] In this embodiment, the locking pin 15 is cylindrical. It is understood that in other embodiments, the locking pin 15 may also be in the form of a ball or other materials, as long as it can lock the first elastic element 16 and slide smoothly on the inner wall of the axial limiting groove 21.

[0061] One end of the adjusting ring 20, relatively close to the size adjusting part 12, protrudes into the interior of the adjusting ring 20 to form an annular protrusion 22. Multiple adjusting grooves 221 are formed on the inner peripheral wall of the annular protrusion 22. Figure 4In the indicated direction, the inner diameter adjusting member 40 can move downward under the drive of the drive ring 30 and disengage from the adjusting groove 221. At this time, the inner diameter adjusting member 40 is located below the annular protrusion 22 and can rotate relative to the lower part of the annular protrusion 22 until the inner diameter adjusting member 40 is aligned with another adjusting groove 221. Then, the inner diameter adjusting member 40 can rise again under the drive of the pushing component 50 and be accommodated in the receiving groove formed by the adjusting groove 221 and the opening groove 13. It can be understood that in other embodiments, the drive ring 30 can also drive the inner diameter adjusting member 40 to move upward and disengage from the adjusting groove 221.

[0062] In order to allow the inner diameter adjusting member 40 to move smoothly back and forth in the adjusting groove 221, the annular protrusion 22 is positioned on the side of the adjusting groove 221 that is relatively close to the wrench engagement portion 11 (i.e. Figure 4 A first guide portion 222 is provided on the lower side of the annular protrusion 22 in the indicated direction. The first guide portion 222 guides the inner diameter adjusting member 40 when it moves to the adjusting groove 221, so that the inner diameter adjusting member 40 can smoothly enter the adjusting groove 221. Specifically, in this embodiment, the first guide portion 222 is an inclined surface; it can be understood that in other embodiments, the first guide portion 222 can also be other shapes, such as a concave surface, as long as it can play a guiding role.

[0063] In this embodiment, there are nine adjusting grooves 221, which are evenly distributed around the annular protrusion 22. The nine adjusting grooves 221 have three different sizes, with three grooves of each size, spaced apart from each other. The nut engagement port 121 in the main body 10 is a hexagonal prism-shaped hole, and there are three inner diameter adjusting members 40. The three inner diameter adjusting members 40 can be located in three adjusting grooves 221 of the same size, and can be simultaneously replaced into three other adjusting grooves 221 of the same size to adjust the inner diameter of the shape formed by the inner diameter adjusting members 40. This arrangement provides good symmetry of the inner diameter adjusting members 40 and a large contact area with the threaded parts, resulting in good stability when clamping the threaded parts. It is understood that in other embodiments, more than nine or fewer than nine adjustment grooves 221 may be provided. Each adjustment groove 221 of the same size may be one, two, four or more, as long as it can achieve the purpose of adjusting the inner diameter of the inner diameter adjustment member 40 to form the inner diameter of the graphic.

[0064] In this application, the three different sized adjustment grooves 221 correspond to three commonly used specifications of threaded parts, such as 19mm, 17mm, and 15mm. It can be understood that the adjustment grooves 221 can also correspond to other specifications of threaded parts, such as 1.6mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 27mm, 30mm, 36mm, etc.

[0065] To facilitate the installation of the inner diameter adjusting component 40 onto the connecting component 31, the inner diameter adjusting component 40 has a mounting groove 41 on the side relatively close to the wrench engagement portion 11. The connecting component 31 on the inner wall of the drive ring 30 includes a mounting block 311 and fixing blocks 312 fixed on both sides of the mounting block 311. The inner diameter adjusting component 40 can be connected to the mounting groove 41 by the engagement of the mounting block 311, and the fixing blocks 312 limit the inner diameter adjusting component 40 to prevent it from coming off from both sides of the mounting block 311. With this configuration, the inner diameter adjusting component 40 can not only be detachably installed on the connecting component 31, facilitating its installation, removal, and replacement, but also the connection between the inner diameter adjusting component 40 and the connecting component 31 is reliable, making it difficult for the inner diameter adjusting component 40 to come off the connecting component 31. It is understood that in other embodiments, the inner diameter adjusting member 40 may also have a mounting block 311, and the inner wall of the drive ring 30 may have a mounting groove 41, as long as a detachable connection between the inner diameter adjusting member 40 and the connecting member 31 can be achieved. Of course, the inner diameter adjusting member 40 and the connecting member 31 may also be integrally formed, or they may be fixedly connected by means of adhesive bonding or other methods.

[0066] Preferably, the fixing block 312 is L-shaped, and the mounting block 311 and the fixing block 312 are joined together on the side of the second elastic member 51 to form a plane or curved surface. This plane or curved surface is used for the second elastic member 51 to abut, thereby improving the installation stability of the second elastic member 51.

[0067] To facilitate the reciprocating movement of the inner diameter adjusting member 40 within the receiving groove, in one embodiment, the inner diameter adjusting member 40 is provided with a second guide portion 42. The second guide portion 42 guides the inner diameter adjusting member 40 as it enters adjusting grooves 221 of different sizes. In this embodiment, the second guide portion 42 is located on the side of the inner diameter adjusting member 40 relatively closer to the drive ring 30 and relatively farther from the wrench engagement portion 11, and the second guide portion 42 is an inclined surface. It is understood that in other embodiments, the second guide portion 42 can also be a concave surface or other shapes, as long as it serves a guiding function.

[0068] In this embodiment, the first guide portion 222 and the second guide portion 42 are provided simultaneously, resulting in a better guiding effect. It can be understood that in other embodiments, if the guiding effect is not considered, either the first guide portion 222 or the second guide portion 42 may be provided.

[0069] To ensure the smooth reciprocating motion of the inner diameter adjusting member 40, in this embodiment, the socket wrench 100 further includes a seat 60, which is fitted onto the wrench engagement portion 11 of the main body 10. The pushing assembly 50 includes a second elastic member 51, which is fitted onto the end of the main body 10 relatively away from the size adjusting portion 12. One end of the second elastic member 51 abuts against the inner diameter adjusting member 40, and the other end abuts against the seat 60. The second elastic member 51 is in a compressed state, capable of applying a force to the inner diameter adjusting member 40 relatively away from the wrench engagement portion. It is understood that the second elastic member 51 can also abut one end against the seat 60 and the other end against the end of the wrench engagement portion 11, or other connection methods can be used, as long as they can provide a thrust to the inner diameter adjusting member 40 relatively away from the wrench engagement portion 11.

[0070] In this embodiment, the second elastic element 51 is a cylindrical spring. It is understood that in other embodiments, the second elastic element 51 may also be a tower spring, a torsion spring, or other types of springs, or other elastic structures, as long as it can provide thrust to the inner diameter adjusting element 40.

[0071] To make the installation of the second elastic element 51 more stable, in this embodiment, the outer diameter of the wrench engagement 11 is smaller than the outer diameter of the size adjustment part 12, and a stepped surface is formed between the wrench engagement 11 and the size adjustment part 12; when the second elastic element 51 is not under force, one end of the second elastic element 51 simultaneously abuts against the inner diameter adjustment part 40 and the stepped surface, thereby improving the installation stability of the second elastic element 51 in the socket wrench 100.

[0072] To further improve the stability of the second elastic member 51 during telescopic movement, the inner wall of the card holder extends inward to form an abutment protrusion 63. The abutment protrusion 63 is used for the second elastic member 51 to abut against and to provide support for the second elastic member 51. It is understood that in other embodiments, the second elastic member 51 may also directly abut against the bottom wall of the seat body 60.
