Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] like Figures 1-6 As shown, this embodiment discloses a screwdriver handle, which includes a housing 1, a tool holder 2, a locking and blocking member 3, an end cap 4, and a tool handle chuck 5.

[0027] The housing 1 is the gripping part, which is a cylindrical sleeve that can be made of materials such as plastic, rubber, or metal. It has an internal cylindrical receiving cavity 15, and the inner wall of the housing 1 has an opening facing a first direction (…). Figure 1 and Figure 2 The guide groove 11 extends in the X direction (as shown in the diagram), with its opening facing the receiving groove. In this embodiment, the housing 1 is formed by splicing two mutually symmetrical parts; in other alternative embodiments, the housing 1 may also be a one-piece structure.

[0028] The tool holder 2 is movably disposed within the receiving cavity 15. It can enter the receiving cavity 15 in the first direction and can also move in the opposite direction. The tool holder 2 can accommodate multiple tool heads 7. One end of the tool holder 2 in the first direction is provided with a slider 21 that matches the guide groove 11. The slider 21 is slidably disposed in the guide groove 11.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the tool holder 2 in this embodiment includes a mounting part 22, a connecting post 23, and a partition plate 24. A slider 21 is provided on the mounting part 22. In this embodiment, the mounting part 22 and the slider 21 are integrally formed. One end of the connecting post 23 is connected to the mounting part 22, and the other end is connected to the end cover 4. The periphery of the connecting post 23 is provided with a plurality of insertion slots capable of holding multiple tool heads.

[0030] A partition plate 24 is disposed in the middle of the connecting post 23, that is, between the mounting part 22 and the end cover 4. The partition plate can divide the insertion slot into upper and lower parts, thereby accommodating more cutting heads and preventing the cutting heads from interfering with each other. More specifically, the insertion slot is formed by two adjacent insertion plates 25. The ends of the insertion plates 25 are respectively forked outward to form two locking hooks 251, thereby facilitating the removal, placement, and replacement of cutting heads. A locking stop 3 is disposed at one end of the housing 1 in the direction opposite to the first direction and is located on the axis of the guide groove 11. The locking stop 3 can prevent the slider 21 from disengaging from the guide groove 11 when it moves away from the first direction, thereby preventing the tool holder 2 from falling out of the receiving cavity 15.

[0031] Specifically, such as Figure 1 As shown, a U-shaped mounting groove 12 is provided at one end of the housing 1 in the direction opposite to the first direction. A snap-fit ​​blocking member 3 is disposed in the mounting groove 12. In this embodiment, the snap-fit ​​blocking member 3 and the housing 1 are integral structures. The snap-fit ​​blocking member 3 is elastic and can elastically deform along the direction of expansion or contraction of the diameter of the receiving cavity 15. Thus, when the tool holder 2 enters the receiving cavity 15 in the first direction, the slider 21 can push the snap-fit ​​blocking member 3 outward (i.e., along the direction of expansion of the diameter of the receiving cavity 15), thereby allowing the tool holder 2 to enter the receiving cavity 15 inside the housing 1. After the tool holder 2 enters the receiving cavity 15, the slider 21 falls into the guide groove 11, and the snap-fit ​​blocking member 3 automatically rebounds and falls into position on the axis of the guide groove 11, thereby preventing the slider 21 from moving away from the first direction and detaching from the guide groove 11, thus preventing the tool holder 2 from falling out of the receiving cavity 15.

[0032] More specifically, such as Figure 1 and Figure 2 As shown, the snap-fit ​​blocking member 3 includes an operating part 31 protruding from the housing 1, an elastic connecting part 32 connecting one end of the operating part 31 to the housing 1, a blocking part 33 that can prevent the slider 21 from moving away from the first direction and disengaging from the guide groove 11, and a snap-fit ​​part 34 that is detachably connected to the end cover 4.

[0033] The operating part 31 is connected to the housing 1 via the elastic connecting part 32, so that the operating part 31 can be lifted upward (i.e., in the direction of increasing diameter of the receiving cavity 15) or pressed downward (i.e., in the direction of decreasing diameter of the receiving cavity 15).

[0034] The blocking part 33 is provided at the outer end of the operating part 31 and has a downward protruding boss. The boss can prevent the slider 21 from moving away from the first direction and disengaging from the guide groove 11.

[0035] The snap-fit ​​part 34 is disposed above the blocking part 33 and protrudes upward, and the snap-fit ​​part 34 can be detachably snapped together with the end cover 4.

[0036] In this embodiment, the snap-fit ​​blocking member 3 is an integral structure, that is, the operating part 31, the elastic connecting part 32, the blocking part 33, and the snap-fit ​​part 34 are integrally formed. Of course, the snap-fit ​​blocking member 3 can also be integrally formed with the housing 1.

[0037] like Figure 6 As shown, the end cap 4 is disposed on one end of the tool holder 2 away from the second direction. The end cap 4 is detachably connected to the snap-fit ​​blocking member 3. Specifically, in this embodiment, a snap-fit ​​groove 41 is provided on the inner wall of the end cap 4 at a position corresponding to the snap-fit ​​part 34, and the snap-fit ​​part 34 can snap into the snap-fit ​​groove 41.

[0038] In this embodiment, pressing the operating part 31 along the diameter reduction direction of the receiving cavity 15 causes the elastic connecting part 32 to deform, allowing the locking part 34 to be inserted into the end cover 4. Stopping pressure on the operating part 31 causes the elastic connecting part 32 to spring back, locking the locking part 34 into the locking groove 41, thus preventing the screwdriver holder 2 from falling out of the receiving cavity 15 when using the screwdriver. Afterwards, when it is necessary to remove or replace the screwdriver tip, simply pressing the operating part 31 disengages the locking part 34 from the locking groove 41. Continuing to press the operating part 31 separates the end cover 4 from the housing 1, allowing the screwdriver holder 2 to be pulled out and the required screwdriver tip 7 to be removed. When the screwdriver holder 2 moves away from the first direction under the guidance of the slider 21 and the guide groove 11, the protrusion on the blocking part 33 abuts against the slider 21, interfering with the slider 21's continued outward movement, thereby preventing the screwdriver holder 2 from falling out of the receiving cavity 15.

[0039] The tool holder chuck 5 is located at one end of the housing 1 in the first direction. The tool holder chuck 5 can fix various types of tool heads 7, specifically, such as... Figures 1-3 As shown, the housing 1 has a connecting groove 13 at one end in the first direction. Multiple V-shaped slots 14 are evenly arranged circumferentially within the connecting groove 13. The end of the tool holder chuck 5 near the housing 1 has a tool holder connecting portion 51 that can be inserted into the connecting groove 13. The tool holder connecting portion 51 has a triangular protrusion 511 that mates with the multiple V-shaped slots 14. In this embodiment, the mounting groove 12 is connected to the receiving groove; in other embodiments, they may not be connected.

[0040] In this embodiment, the above-described structure allows for a more convenient and stable installation of the tool holder chuck 5 onto the housing 1.

[0041] Furthermore, such as Figure 5 As shown, a ratchet structure 52 is provided at the end of the chuck 5 away from the housing 1, and the ratchet structure 52 is connected to the cutter head 7.

[0042] In this embodiment, a ratchet structure 52 is provided, which can rotate and remove screws in narrow or hard-to-access locations, improving applicability.

[0043] Furthermore, in this embodiment, there are two guide grooves 11, two snap-fit ​​blocking members 3, two sliders 21, and two snap-fit ​​grooves 41 inside the end cover 4. The two guide grooves 11 are symmetrically arranged along the axis of the receiving cavity 15, and the positions of the sliders 21 and snap-fit ​​blocking members 3 correspond to the positions of the guide grooves 11.

[0044] In this embodiment, the above-described structure can more stably guide the tool holder 2 to move in the first direction or in the opposite direction within the receiving cavity 15.

[0045] In other alternative embodiments, the number of guide grooves 11, snap-fit ​​blocking members 3, and sliders 21 is not limited to two, and their positions are not limited to being symmetrically arranged along the axis in this embodiment.

[0046] Furthermore, such as Figure 1 As shown, the outer side of the screwdriver handle housing 1 in this embodiment is also covered with an anti-slip sleeve 6 made of rubber or other materials, which can increase friction and provide an anti-slip function.

[0047] In this embodiment, the screwdriver handle has a guide groove 11 on the inner wall of the housing 1, and a slider 21 that can slide in the guide groove 11 is provided on the tool holder 2. By improving the original structure, the cost can be reduced. A snap-fit ​​blocking member 3 is provided to snap the end cap 4 and to interfere with the movement of the slider 21, thereby preventing the slider 21 on the tool holder 2 from sliding out of the guide groove 11. This also prevents the tool holder 2 from falling out of the receiving cavity 15 when the tool head 7 is being picked up and replaced.

[0048] The following points need to be explained: (1) The accompanying drawings of this utility model embodiment only involve the structure involved in this utility model embodiment. Other structures can refer to the general design.

[0049] (2) Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
