The socket tool holder 100 is used for assembling an existing socket tool 200. The socket tool 200 is formed with a quadrangular socket 201; the socket tool holder 100 includes a base 10, a rotating The socket 20, a segmented positioning member 30 and a disengagement prevention member 40; wherein, the base 10 includes a chassis 11 and a protruding shaft 12, the protruding shaft 12 is formed with at least one abutting plate extending laterally 13 (Note: this example is two symmetrical configuration types); the rotating socket 20 includes a seat 21 and a quadrangular socket 22, The quadrangular socket 22 is used for assembling the quadrangular socket 201 of the socket tool 200. A hollow cavity 221 is formed inside the quadrangular socket 22, and at least one elastic piece 222 is formed in the hollow cavity 221. Each elastic piece A blocking portion 223 is formed on the outer side of the 222. When the elastic piece 222 is supported by the at least one abutting plate 13 into a rigid state, the blocking portion 223 is positioned at the quadrangular socket 201 to prevent the socket tool 200 from coming off. The seat 21 is formed with an escape hole 23, and the contour shape of the escape hole 23 must be passed through by the protruding shaft 12 of the base 10 and the at least one abutting plate 13 to enter the hollow cavity 221; the segment The positioning member 30 includes at least one engaging protrusion 33 and a first segment of the engaging portion 31 and the second segment of engaging portion 32 for the at least one engaging protrusion 33 to be selectively aligned and engaged, wherein the at least one engaging portion 33 is engaged. The protruding portion 33 is formed on the protruding shaft 12 of the base 10 , and the first segment 31 and the second segment 32 are formed at the corresponding positions of the seat portion 21 ; the disengagement prevention member 40 , Located in the hollow cavity 221 , it includes an anti-drop blocking edge 41 formed at a predetermined height position of the protruding shaft 12 of the base 10 in a laterally relative diameter-expanding shape. The anti-drop blocking edge 41 has elastic properties and Its outer diameter must be larger than the corresponding hole diameter of the avoidance hole 23 . When the protruding shaft 12 passes through the avoidance hole 23 , the anti-detachment baffle 41 is forced to pass through the avoidance hole 23 in an interference fit state. in the hollow cavity 221 , thereby preventing the protruding shaft 12 from coming out of the hollow cavity 221 in reverse; thereby, the segmented positioning member 30 and the anti-dropping member 40 are both arranged on the lateral contour of the quadrangular socket joint 22 The configuration type within the projected range.

With the above-mentioned structural composition and technical features, the socket tool placement base 100 disclosed in the present invention is first shown in FIG. 3 to FIG. 6 in actual use, which is a set positioning state.

Therefore, at this time, the blocking portion 223 cannot locate the quadrangular socket 201 (as shown in FIG. 1 ), which constitutes a release state in which the socket tool 200 can be disengaged. The main purpose of the present invention is to make both the segmented positioning member 30 and the anti-detachment member 40 set within the projection range of the lateral contour of the quadrangular socket joint 22, so that the socket tool can be placed in the seat product. The outer diameter volume can be further reduced, so as to better meet the development trend of miniaturization design of tool products.

As shown in FIG. 9 to FIG. 15 , in this example, the periphery of the seat 21 of the rotating socket 20 further extends to form an outer disk 24 beyond the projection range of the lateral profile of the quadrangular socket 22 , and the outer disk A circular matching portion 25 is formed at the bottom of the portion 24 (note: this example is in the shape of a groove, but it can also be in the shape of a bump), and the chassis 11 of the base 10 is correspondingly formed with a circular guide portion 115 (note: This example is in the shape of a bump, but also in the shape of a groove), and the circular guide portion 115 is used for the circular matching portion 25 to be assembled together, so as to provide a more stable rotation guiding and leaning effect.

As shown in FIG. 2 and FIG. 4 , in this example, the height position of the disengagement-preventing baffle 41 is the same as the height position of the bottom ends of the two abutting plates 13 .

As shown in FIG. 2 and FIG. 4 , in this example, the disengagement-preventing member 40 further includes an inclined guide surface 42 integrally extended from the disengagement-preventing baffle 41 and connected to the protruding shaft 12 ; The function of the inclined guide surface 42 is mainly to enable the anti-falling blocking edge 41 to obtain the guiding function of the inclined surface during the process of forcibly passing over the avoidance hole 23 and to be more smooth.

As shown in FIG. 16 , in this example, the anti-detachment member 40 further includes an inclined guide edge 43 formed in the escape hole 23 , and the inclined guide edge 43 has a diameter-reduced end 431 and an enlarged diameter end 432 ; this example The inclined guide edge 43 in the middle is correspondingly matched with the anti-separation blocking edge 41, wherein The outer diameter of the enlarged diameter end 432 is larger than the outer diameter of the anti-detachment retaining edge 41 , and the outer diameter of the reduced diameter end 431 is smaller than the outer diameter of the anti-detachment retaining edge 41 . As disclosed in the previous paragraph, the anti-falling blocking edge 41 can obtain the guiding function of the inclined surface during the process of forcibly passing over the avoidance hole 23 , so as to be smoother.

As shown in FIG. 2 , in this example, the first-stage inserting portion 31 and the second-segment inserting portion 32 of the segmented positioning member 30 are formed in the portion of the seat portion 21 that avoids the through hole 23 The position of the hole wall constitutes an arrangement pattern in which the first-stage inserting portion 31 , the second-stage inserting portion 32 and the escape hole 23 are arranged at the same height level. The effect of the embodiment disclosed in this example not only reduces the width of the structure of the present invention, but also further reduces the height and has a better miniaturization effect.

As shown in FIG. 3 , in this example, the avoidance hole 23 cooperates with the at least one abutment plate 13 to form at least one wing hole 235 , so that the first segment of the inserting portion 31 , the second segment of the inserting portion 32 and the The at least one wing hole portion 235 is arranged in a mutually staggered relationship.

As shown in FIG. 17 , in this example, the avoidance hole 23 cooperates with the at least one abutting plate to form at least one wing hole portion (the reference numeral is omitted here), and the one wing hole portion is used as the first segment of the inserting portion at the same time. 31 use.

As shown in FIG. 9 , in this example, the first-stage inserting portion 31 and the second-segment inserting portion 32 of the segmented positioning member 30 are formed at the bottom of the seat portion 21 to form the first segment The inserting portion 31 , the second-stage inserting portion 32 and the avoidance hole 23 are arranged in different height levels.
