DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0036] Please also read Figure 1 and Figure 2According to a first aspect of an embodiment of the utility model, a universal hexagon socket wrench 1 is provided. The wrench 1 comprises a wrench body 10, a plurality of movable parts 11 and a retaining structure 12. The wrench body 10 has a mounting surface 100. The wrench body 10 is provided with a plurality of first slide grooves 102 arranged at intervals around a center line X. The first slide grooves 102 are arranged to extend radially along the center line X. The plurality of movable parts 11 can together constitute a clamping portion for clamping a hexagon socket bolt. The number of the plurality of first slide grooves 102 is the same as the number of the plurality of movable parts 11. The plurality of movable parts 11 can be slidably connected to each of the first slide grooves 102. The plurality of movable parts 11 can slide to different preset positions relative to the mounting surface 100 to adjust the size of the constituted clamping portion. The retaining structure 12 is provided on the mounting surface 100. The retaining structure 12 is used to hold the plurality of movable parts 11 at preset positions, wherein the center line X is perpendicular to the mounting surface 100.

[0037] The wrench 1 provided by the embodiment of the utility model is provided with a plurality of movable members 11, and the plurality of movable members 11 together constitute a clamping portion, so that the outer contour of the clamping portion can be clamped with the hexagon socket bolt, and a plurality of first slide grooves 102 are provided around the center line X on the wrench body 10, and the plurality of movable members 11 can slide on the plurality of first slide grooves 102 along the radial direction of the center line X relative to the mounting surface 100 to different preset positions (such as Figure 2 and Figure 3 The movable parts 11 shown are in different preset positions), so that the size of the engaging portion changes, so that the formed engaging portion can engage with hexagon socket bolts of different sizes, thereby making the wrench 1 adaptable to the use of hexagon socket bolts of different specifications, with good versatility and convenient use. At the same time, by setting a retaining structure 12, the retaining structure 12 can hold multiple movable parts 11 in preset positions, thereby avoiding the situation where the movable parts 11 move and cannot engage with the hexagon socket bolts during the use of the wrench 1.

[0038] For example, when the multiple movable members 11 slide relative to the mounting surface 100 and approach each other, the size of the engaging portion becomes smaller; and when the multiple movable members 11 slide relative to the mounting surface 100 and move away from each other, the size of the engaging portion becomes larger. It can be seen that, by adopting the solution of the present application, the positions of the multiple movable members 11 can be adjusted according to the specifications of the hexagon socket bolts, so that the formed engaging portion can be adapted to the hexagon socket bolts of different specifications, and the adaptability and versatility are better.

[0039] It is understandable that, in actual use, when the plurality of movable members 11 are engaged with the hexagon socket bolt, the position where the center line of the wrench 1 is aligned with the hexagon socket bolt is the position where the center line X of the wrench 1 is located.

[0040] Optionally, the wrench body 10 may be a plate-like structure, a columnar structure or a rod-like structure, etc., as long as it is convenient for the user to hold it. The specific selection can be made according to actual conditions and is not specifically limited in this embodiment.

[0041] Optionally, the number of the movable members 11 may be two, three, four or five, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment. Figure 2 As shown, Figure 2 2 shows an example in which the number of movable members 11 is three.

[0042] In some embodiments, the wrench 1 further includes a transmission structure 13, which is used to drive the multiple movable parts 11 to slide simultaneously. In this way, the transmission structure 13 can drive the multiple movable parts 11 to slide simultaneously, which can facilitate the movement of the multiple movable parts 11 at the same time, and is conducive to improving the synchronization of the multiple movable parts 11 when sliding, so that the multiple movable parts 11 can better engage with the hexagon socket bolts.

[0043] In other embodiments, a plurality of transmission structures 13 may be provided to respectively drive the movable member 11 to slide. For example, a plurality of connecting rod mechanisms may be provided to respectively drive the movable member 11 to slide by pulling the rods respectively.

[0044] Please also read Figure 2 and Figure 4 In some embodiments, the transmission structure 13 includes a rotating member 130, which is arranged between the mounting surface 100 and the movable member 11. The rotating member 130 is provided with a plurality of second slide grooves 1300, and the number of the second slide grooves 1300 is the same as the number of the movable members 11. Each movable member 11 is provided with a protrusion 1110 on the side facing the rotating member 130, and each protrusion 1110 is respectively slidably connected to the corresponding second slide groove 1300. The rotating member 130 can rotate around the center line X relative to the mounting surface 100 to drive the movable member 11 to slide relative to the first slide groove 102. The retaining structure 12 is used to maintain the rotation angle of the rotating member 130, and the axis of the rotating member 130 coincides with the center line X. In this way, the protrusion 1110 of the movable member 11 is slidably connected with the second slide groove 1300. When the rotating member 130 rotates, the multiple second slide grooves 1300 and the multiple protrusions 1110 slide relative to each other, so that under the drive of the protrusion 1110, the multiple movable members 11 slide radially relative to the multiple first slide grooves 102 along the center line X at the same time, which is conducive to improving the synchronization of the sliding of the multiple movable members 11, so that the multiple movable members 11 can be better engaged with the hexagon socket bolts. In addition, the holding structure 12 only needs to maintain the rotation angle of the rotating member 130 to simultaneously maintain the positions of the multiple movable members 11, without having to maintain the positions of the multiple movable members 11 separately, which is conducive to simplifying the structure of the holding structure 12.

[0045] In other embodiments, the transmission structure 13 may also include a gear and multiple racks. The multiple racks are arranged at intervals along the rotation direction of the gear and are all meshed with the gear. The multiple movable parts 11 are respectively connected to each rack. When the gear rotates, the multiple racks move linearly along different tangential directions, thereby simultaneously driving the multiple movable parts 11 to slide relative to the corresponding first slide groove.

[0046] Optionally, the second slide groove 1300 may be a slide groove having a cross-sectional shape of a circular arc, an elliptical arc, a parabola, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0047] In some embodiments, a plurality of second slide grooves 1300 are arranged at intervals around the center line X, and the distance between the second slide grooves 1300 and the center line X gradually increases along the rotation direction of the rotating member 130. In this way, when the rotating member 130 rotates along the rotation direction, the second slide grooves 1300 will push the protrusions 1110 to move in the radial direction of the center line X in a direction away from the center line X, so that the plurality of movable members 11 slide relative to the mounting surface 100 and move away from each other. When the rotating member 130 rotates in a direction opposite to the rotation direction, the second slide grooves 1300 will push the protrusions 1110 to move in the radial direction of the center line X in a direction close to the center line X, so that the plurality of movable members 11 slide relative to the mounting surface 100 and move closer to each other.

[0048] Optionally, the rotating member 130 may be a gear or a turntable, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0049] In some embodiments, the rotating member 130 is a gear, and the transmission structure 13 also includes a worm 131. The worm 131 is disposed on the mounting surface 100 and is meshingly connected to the rotating member 130. The worm 131 can rotate around a first direction Y relative to the mounting surface 100 to drive the rotating member 130 to rotate. The first direction Y is a direction perpendicular to the center line X.

[0050] In this way, the gear can be driven to rotate by rotating the worm 131, and the cooperation of the gear and worm 131 has a good deceleration effect, so that the adjustment of the angle of gear rotation is more precise, that is, the adjustment of the positions of multiple movable parts 11 is more precise, so that the multiple movable parts 11 can better engage with the hexagon socket bolts. At the same time, the cooperation of the gear and worm 131 has a large bearing capacity and good wear resistance, which can improve the reliability and service life of the wrench 1.

[0051] Please also read Figure 5 and Figure 6 In some embodiments, a mounting hole 101 is provided on the mounting surface 100, and a rotating shaft 1301 is provided on the gear, and the rotating shaft 1301 is rotatably connected to the mounting hole 101. In this way, the gear can be installed in the mounting hole 101 and can rotate around the center line X relative to the mounting surface 100.

[0052] Please refer again Figure 2 In some embodiments, the wrench 1 further includes two fixing blocks 14 , which are arranged on the mounting surface 100 at intervals along the first direction Y, and both ends of the worm 131 are rotatably connected to the two fixing blocks 14 .

[0053] In this way, by arranging two fixing blocks 14 at intervals along the first direction Y on the mounting surface 100, the two fixing blocks 14 can fix the worm 131 to the mounting surface 100, and the worm 131 can rotate around the first direction Y, so that when the worm 131 rotates, it can drive the gear to rotate around the center line X.

[0054] In actual operation, the user can rotate the spiral teeth of the worm 131 to rotate the rotating member 130, thereby driving the movable member 11 to slide relative to the mounting surface 100, thereby adjusting the size of the engaging portion.

[0055] Optionally, the retaining structure 12 can directly maintain the positions of the multiple movable parts 11. For example, the retaining structure 12 may include a plurality of buckles arranged on the mounting surface 100. After the movable parts 11 move to the preset positions, the plurality of buckles are respectively engaged with the movable parts 11. The retaining structure 12 can also maintain the positions of the multiple movable parts 11 by maintaining the angle of the rotating part 130. For example, the retaining structure 12 may include a retaining arm 120. After the rotating part 130 rotates to the preset angle, the retaining arm 120 is engaged with the rotating part 130 (the tooth groove on the gear), thereby maintaining the multiple movable parts 11 at the preset positions.

[0056] See also Figure 7 In some embodiments, the retaining structure 12 includes a retaining arm 120, an elastic member 121 and a limit member 122. One end of the retaining arm 120 is connected to the mounting surface 100 for rotation around a second direction Z. One end of the elastic member 121 is connected to the other end of the retaining arm 120. The other end of the elastic member 121 is connected to the wrench body 10. The elastic member 121 is used to provide an elastic reset force so that the retaining arm 120 is engaged with the rotating member 130. The limit member 122 is provided on the mounting surface 100. The limit member 122 can rotate around the second direction Z relative to the mounting surface 100. The limit member 122 is configured to limit the position of the retaining arm 120 relative to the wrench body 10. The second direction Z is a direction parallel to the center line X.

[0057] In this way, when it is necessary to adjust the position of the movable part 11, the limit member 122 is rotated so that the limit member 122 abuts against the retaining arm 120, and the retaining arm 120 is rotated to be disengaged from the rotating member 130. At this time, the retaining arm 120 will not be engaged with the rotating member 130, and the rotating member 130 rotates around the center line X, thereby driving the multiple movable parts 11 to move. When it is necessary to maintain the position of the movable part 11, the limit member 122 is rotated so that the limit member 122 is disengaged from the retaining arm 120. Since the elastic member 121 is pressed between the wrench body 10 and the retaining arm 120, the elastic force provided by the elastic member 121 will cause the retaining arm 120 to rotate around the second direction Z until it is engaged with the rotating member 130, thereby blocking the rotation of the rotating member 130, and then keeping the multiple movable parts 11 in the preset position. Therefore, the user only needs to adjust the limit member 122 to make the retaining arm 120 engage with or disengage from the rotating member 130. The structure is simple and the operation is easy.

[0058] Optionally, the elastic member 121 may be a spring or a spring sheet, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0059] Optionally, the retaining arm 120 may be a columnar structure or a rod-shaped structure, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

[0060] Optionally, the limiting member 122 may be a block structure or a columnar structure, etc., which may be selected according to actual conditions and is not specifically limited in this embodiment.

By setting the wrench body 10 as the base 10a and the cover plate 10b, the cover plate 10b and the base 10a can enclose and form the receiving cavity 10c, so as to accommodate and protect the various components of the wrench 1 (such as the movable part 11 and the retaining structure 12, etc.).

[0062] In some embodiments, the cover plate 10b of the wrench body 10 is provided with a first avoidance hole 103 connected to the accommodating cavity 10c, and the first avoidance hole 103 is used to allow the helical teeth of the worm 131 to be at least partially exposed to the cover plate 10b. In this way, the user can rotate the rotating member 130 by rotating the helical teeth of the worm 131 exposed to the cover plate 10b, thereby adjusting the position of the movable member 11, which is convenient to use.

[0063] In some embodiments, the cover plate 10b of the wrench body 10 is provided with a second avoidance hole 104 connected to the accommodating cavity 10c, and the retaining structure 12 also includes a handle 123, which is provided on the cover plate 10b and away from the accommodating cavity 10c, and the handle 123 is connected to the limit member 122 through the second avoidance hole 104.

[0064] In this way, by providing a handle 123 outside the cover plate 10b, the user can rotate the limit member 122 by rotating the handle 123, so that the retaining arm 120 is engaged with or disengaged from the rotating member 130, which is convenient to use.

[0065] In some embodiments, the first slide groove 102 is provided on the cover plate 10b, the first slide groove 102 penetrates the cover plate 10b in a direction parallel to the center line X, and is connected to the accommodating cavity 10c, and at least a portion of the movable member 11 is exposed to the cover plate 10b from the first slide groove 102. In this way, at least a portion of the movable member 11 can be exposed to the cover plate 10b from the first slide groove 102, and the portion of the movable member 11 exposed to the cover plate 10b can abut against the hexagon socket bolt.

[0066] In other embodiments, the first slide groove 102 may also be disposed on the base 10a, so that the protrusion 1110 of the movable member 11 is slidably connected to the first slide groove 102 and the second slide groove 1300 at the same time.

[0067] See also Figure 8 In some embodiments, the movable member 11 includes a contact portion 110 and a sliding portion 111. The sliding portion 111 is slidably connected to the first slide groove 102, and a protrusion 1110 is provided on the sliding portion 111. The contact portion 110 is connected to the sliding portion 111 and exposed to the cover plate 10b. In this way, the protrusion 1110 of the sliding portion 111 can cooperate with the second slide groove 1300 and slide under the drive of the rotating member 130, so that the contact portion 110 abuts against the hexagon socket bolt.

[0068] In some embodiments, a slide rail 105 (such as Figure 1 As shown in FIG. 1 , the sliding portion 111 is provided with a slider 1111, and the slider 1111 is slidably connected to the slide rail 105. In this way, through the cooperation of the slider 1111 and the slide rail 105, the sliding of the movable member 11 relative to the first slide groove 102 can be made more stable.

[0069] In some embodiments, the movable member 11 is provided with a positioning portion 1100 , and the plurality of movable members 11 can slide relative to the mounting surface 100 to approach each other so that the plurality of positioning portions 1100 abut against each other.

Moreover, the plurality of movable parts 11 can be at the same position each time they are reset, and the center line X always passes through the center of the plurality of movable parts 11. Even if there is a deviation in synchronization when the plurality of movable parts 11 move, the synchronization of the plurality of movable parts 11 can be restored when the plurality of movable parts 11 are reset, thereby improving the reliability of the wrench 1.
