DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, several embodiments of the present invention will be described with reference to the drawings. For the sake of clarity, many practical details will be described below. However, it should be understood that these practical details should not be intended to limit the present invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, in order to simplify the drawings, some known or conventional structures and components are simply and diagrammatically shown in the drawings, and overlapping components may be represented by using the same or similar symbols.

[0019] (First embodiment) 1 and 2, FIG. 1 is an exploded view of a socket structure 100 according to a first embodiment of the present invention, and FIG. 2 is a schematic three-dimensional view of the socket structure 100 of FIG. 1. The socket structure 100 includes a socket body 110 and a polygonal drive structure 120. The socket body 110 has a first mounting hole 111 and a second mounting hole 112, the first mounting hole 111 is provided at one end of the socket body 110 along the central axis of the socket structure 100, and the second mounting hole 112 is provided at the other end of the socket body 110 along the central axis of the socket structure 100, and the first mounting hole 111 and the second mounting hole 112 are connected to each other. The first mounting hole 111 is used to engage a hand tool such as a square wrench to rotate and drive the socket structure 100, and the second mounting hole 112 is used to engage a fastener such as a screw.

[0020] The polygonal drive structure 120 is provided around the outer peripheral wall of the socket body 110 and surrounds the first mounting hole 111. In particular, the socket body 110 may include a drive end surface 113, which is perpendicular to the central axis, and the first mounting hole 111 may be drilled in the drive end surface 113. The polygonal drive structure 120 may include a plurality of teeth 121, each of which extends from the drive end surface 113 along a direction parallel to the central axis, and each of the teeth 121 may have a rectangular column shape with a long side parallel to the central axis. In this way, the socket structure 100 having the teeth 121 can be fitted with a ratchet wrench to rotate the socket structure 100, so that the first mounting hole 111 and the polygonal drive structure 120 can be combined with different manual tools, thereby increasing the diversity of the driving method of the socket structure 100.

[0021] The socket structure 100 may further include a recessed space 122, an elastic member 123, and a ball plunger 124. The recessed space 122 is provided in the polygonal driving structure 120 along the radial direction of the central axis. The elastic member 123 is provided in the recessed space 122. The ball plunger 124 is connected to one end of the elastic member 123, and a part of the ball plunger 124 protrudes from the recessed space 122. When a hand tool (not shown) is engaged with the polygonal driving structure 120, the ball plunger 124 can be pressed against the engagement hole of the hand tool, which is advantageous for engagement and fixation, and makes the engagement of the hand tool more stable.

[0022] 2, the depth of the first mounting hole 111 and the second mounting hole 112 can be greater than the height of the hand tool or fastener to be engaged, so that when the hand tool engages the first mounting hole 111, it extends beyond the first mounting hole 111 into the second mounting hole 112 and presses against the fastener, preventing the fastener from disengaging from the second mounting hole 112. However, the present invention is not limited thereto.

[0023] Referring to Fig. 3, Fig. 3 is a schematic side view showing the socket structure 100 of Fig. 1. The socket structure 100 has a maximum height L1 along the central axis, and the polygonal driving structure 120 has an axial length L2 along the central axis, the axial length L2 being less than or equal to half of the maximum height L1. Furthermore, the axial length L2 may be 34% to 42% of the maximum height L1. This ensures that the socket body 110 and the polygonal driving structure 120 have an appropriate ratio.

[0024] 3, the polygonal drive structure 120 has a first width L3 along the radial direction of the central axis, and the socket body 110 has a second width L4 along the radial direction of the central axis, the first width L3 being larger than the second width L4. This allows the effort arm to be larger than the load arm when the socket structure 100 is fitted and rotated with a ratchet wrench, resulting in a labor-saving effect.

[0025] Second embodiment 4 and 5, FIG. 4 is a schematic three-dimensional view of a socket structure 200 according to a second embodiment of the present invention, and FIG. 5 is another schematic three-dimensional view of the socket structure 200 of FIG. 4.

In the second embodiment, each tooth portion 221 of the polygonal driving structure 220 has a sharp triangular prism shape, and the end surface that is flush with the driving end surface 213 of the polygonal driving structure 220 has a star-shaped polygon shape.

[0026] Furthermore, the socket structure 200 may include a drive hole 230 drilled in the socket body 210 and communicating with the second mounting hole 212 along the radial direction of the central axis. The drive hole 230 is used to allow a hand tool (not shown) to engage with the socket body 210 from a side edge thereof, and a user can apply force from the side edge of the socket body 210 to rotate the socket structure 200, thereby enabling the socket structure 200 to complete attachment and detachment of a fastener even in a space lacking in vertical height.

[0030] More specifically, the driving hole 430 can be communicated with the first fitting hole 411 by penetrating the stepped portion 422 of the polygonal driving structure 420 and the socket body 410 along the radial direction of the central axis, and the method by which the user rotates the socket structure 400 using the driving hole 430 is similar to the socket structures 200 and 300 described above, so a detailed description thereof will be omitted here. Furthermore, the stepped portions 422 are formed on both opposing sides of the polygonal driving structure 420, and can be clamped with an open-end wrench to rotate the socket structure 400.

[0031] Fifth embodiment 8, a schematic three-dimensional view of a socket structure 500 according to a fifth embodiment of the present invention is shown.
