[0029] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, one of ordinary skill in the art will understand other possible embodiments and the advantages of the present invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figures 1-8 As shown, this embodiment provides a pop-up storage unit for screwdriver bits, including a cylindrical shell 1 and a pop-up device 2 located in the shell 1 .

[0033] The housing 1 has a cavity 10 opened along an axial direction. The cavity 10 is open at one end and closed at the other end. A slot 11 is provided on the inner wall of the cavity 10 near the opening.

[0034] The pop-up device 2 includes a clamping member 21, a pop-up block 22 and an elastic member 23, wherein the clamping member 21 is movably installed at the bottom of the cavity 10, and has a force-applying portion 211 extending outside the cavity 10 and a hook portion 212 capable of clamping the pop-up block 22. A reset spring (not shown in the figure) is also provided on the clamping member 21. The reset spring generates an elastic force to reset the clamping member 21 so that it can be clamped again when the pop-up block 22 is pressed back.

[0035] The ejection block 22 includes an outer retaining ring 221 configured to match the shape of the cavity 10 and an ejection member 222 sleeved within the outer retaining ring 221. Since the cavity 10 in this embodiment is cylindrical, the outer retaining ring 221 has a generally cylindrical shape. The center portion of the outer retaining ring 221 is hollowed out along the axial direction of the cavity 10, providing the outer retaining ring 221 with an annular peripheral wall. The peripheral wall of the outer retaining ring 221 is provided with at least one retaining structure 2211, which engages with the retaining groove 11 on the inner wall of the cavity 10 to prevent the outer retaining ring 221 from slipping out of the opening of the cavity 10.

[0036] The limiting structure 2211 can be assembled in the cavity 10 by being radially converged. When it moves to the position of the locking slot 11, it is locked in the locking slot 11 by the elastic force of the limiting structure 2211, thereby preventing the outer fixing ring 221 from being separated from the cavity 10. The limiting structure 2211 can be an elastic ring mounted on the outer fixing ring 221, a ball screw fixed to the outer fixing ring 221, or other structures.

[0037] Since the pop-up block 22 in this embodiment is usually a plastic part or a metal part, the limiting structure 2211 can be directly formed by the peripheral wall of the outer fixing ring 221, that is, a hook 2212 is formed on the peripheral wall of the outer fixing ring 221, and only the upper end of the hook 2212 is connected to the peripheral wall of the outer fixing ring 221, so that the hook 2212 can have a certain elastic deformation ability, so that it can be radially contracted along the cavity 10 and assembled in the cavity 10. When it moves to the position of the slot 11, it uses its accumulated elastic force and is locked in the slot 11 to prevent the outer fixing ring 221 from detaching from the cavity 10.

[0038] The outer fixing ring 221 has a plurality of bit fixing members 223 on the top away from the bottom of the cavity 10 . These bit fixing members 223 are arranged on the top of the outer fixing ring 221 . Each bit fixing member 223 is used to fix and accommodate at least one screwdriver bit 3 .

[0039] The ejector 222 is sleeved within the outer retaining ring 221. The bottom of the ejector 222 has a hook portion 2221 that mates with the hook portion 212 of the latch 21. The top outer wall of the ejector 222 has several radially recessed grooves 2222, each corresponding to a tool bit retainer 223. The middle portion of the tool bit retainer 223 is hingedly secured to the top of the outer retaining ring 221, forming a seesaw-like structure. Its bottom has an extension portion 2231 that extends roughly horizontally into the groove 2222, and its top has a retaining cavity 2232 for accommodating a screwdriver bit.

[0040] The elastic member 23 (a spring in this embodiment) is installed on the bottom of the cavity 10 and acts on the bottom of the ejector 222 to generate an elastic force to push the ejector toward the opening of the cavity 10 .

[0041] The process of using the pop-up storage unit for screwdriver bits provided in this embodiment is as follows:

[0042] In the storage state, the hook portion 2221 at the bottom of the ejector 222 is hooked and fixed by the hook portion 212 of the clamping member 21, and generates a force to compress the elastic member 23. At this time, the pop-up block 22 is located at the lower part of the cavity 10 along with the ejector 222, and the screwdriver head 3 is also retracted in the cavity 10.

[0043] When the screwdriver head 3 needs to be used, the clamping member 21 is pushed to disengage the hook portion 212 of the clamping member 21 from the hook portion 2221 at the bottom of the ejecting member 222. At this time, the elastic force of the elastic member 23 pushes the ejecting member 222 and the outer fixing ring 221 toward the opening direction. When the limiting structure 2211 on the outer fixing ring 221 moves to the position of the card slot 11 of the cavity 10, the limiting structure 2211 pops out and is connected to the card slot 11, thereby limiting the movement of the outer fixing ring 221 and allowing the tool head fixing member 223 on the top of the outer fixing ring 221 to extend out of the cavity 10. At the same time, the ejecting member 222 acts on the extension portion 2231 at the bottom of the tool head fixing member 223 to make the upper part of the tool head fixing member 223 flip outward, so that the screwdriver head 3 fixed on the tool head fixing member 223 can be expanded outward, forming a Figure 6 As shown in the state, the screwdriver head 3 can occupy a smaller storage space in the storage state, while there is a wider gap between adjacent screwdriver heads for easy access when in use.

[0044] After use, the outer fixing ring 221 and the ejector 222 are pushed toward the bottom of the cavity 10 together with a force, so as to push the outer fixing ring 221 and the ejector 222 to the bottom of the cavity 10, and the hook portion 212 of the clamping member 21 hooks the hook portion 2221 at the bottom of the ejector 222, so that the pop-up storage unit of the screwdriver bit provided in this embodiment is restored to the storage state.

[0045] In this embodiment, a cavity 220 is formed in the middle of the top surface of the ejection block 22, and a plurality of bit fixing members 223 are arranged around the cavity to form a space for accommodating the screwdriver handle on the ejection block 22. Preferably, a cover (not shown) is also included. The cover covers the open end of the housing, and when the clamping member 21 clamps the ejection block 22, the screwdriver handle placed on the ejection block is located in the chamber surrounded by the cover and the housing. The cover can form a sealed chamber in the housing to prevent dust and other foreign objects from contaminating the screwdriver bit. In addition, the screwdriver handle can be used to restore the ejection block 22 to the storage state, making it easier to reset the pop-up storage unit.

[0046] Example 2

[0047] refer to Figure 9 This embodiment further provides a screwdriver bit storage structure, which includes two pop-up storage units as described in Example 1, and the openings of the shells 1 of the two pop-up storage units have mutually matching threaded connection structures, that is, the shell 1 of one pop-up storage unit is provided with an internal thread structure, and the shell 1 of the other pop-up storage unit is provided with a matching external thread structure, so that the shells 1 of the two pop-up storage units can be threadedly connected to each other into a whole and form a sealed chamber to prevent dust and other foreign objects from contaminating the screwdriver bits.

[0048] In this embodiment, reference Figure 9 and Figure 10 The pop-up blocks 22 of the two pop-up storage units are arranged opposite to each other, and there is a concave cavity 220 on the middle part of the top surface. A plurality of tool bit fixing members 223 are arranged around the concave cavity 220 to form a space for placing the bolt driver handle 4 between the two pop-up blocks 22, so that the tool handle and the tool bit can be stored simultaneously in the screwdriver bit storage structure. At the same time, after the tool is used, the pop-up block 22 can be restored to the storage state with the help of the bolt driver handle 4, which is more convenient for resetting the pop-up storage unit.

[0049] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
