[0066] As shown in Fig. 5, for the second, third and fourth embodiments of the present application, at least one blocking mechanism 30 is provided at a proper position of the bit accommodating tube 20, so that each bit 10 can only pass through the position and cannot be reset. The blocking mechanism 30 can be formed by a conventional blocking mechanism or structure, or as shown in Fig. 5, a roughly annular blocking structure Al is used as the blocking mechanism 30. The annular blocking structure Al can be annularly closed Al 1 or open Al 2. The blocking structure Al is provided with at least one inwardly bent elastic arm Al 3 (in this embodiment, two elastic arms Al 3, Al 4 are used as the blocking structure). The through slot 203 of the bit accommodating tube 20 is also provided with a corresponding annular recess 203A at a proper position. By accommodating the blocking structure Al, the bit 10 is pushed by the previous bit 10A, so that the bit 10 passes through the slot hole A 15 of the blocking structure Al, and after the bit 10 passes through, the elastic arms Al 3, Al 4 are opened from the outside of the positioning structure section 101 of the bit 10, and then the bit 10 is reset by the elastic arms Al 3, Al 4 on the top surface of one end 103 of the bit 10, so that the bit 10 is blocked and cannot be reset (for the second embodiment of the present application). The annular blocking structure Al can be made of metal or alloy or rigid plastic or plastic compound, or metal with magnetic material.

[0067] As shown in Fig. 5, another blocking mechanism 30A can be provided at a proper position of the bit accommodating tube 20, which is at least one inwardly bent elastic arm B20 (in this embodiment, two elastic arms B201, B202 are used as the blocking structure). The elastic arms B201, B202 are provided with through slots B203 around three edges of the elastic arms B201, B202, so as to facilitate the bending and resetting mechanism of the elastic arms B201, B202. The function is the same as that of the second embodiment (for the third embodiment of the present application).

[0068] As shown in Fig. 5, the holding portion 204 near one end of the bit accommodating tube 20 can be designed to be separated from the bit accommodating tube 20, or integrally formed with the holding portion 204 (in this embodiment, the holding portion 204 is integrally formed with the bit accommodating tube 20). The size, appearance and material (metal or alloy or metal or alloy combined with plastic) of the holding portion 204 and the bit accommodating tube 20 can be designed to be matched with each other as needed, so as to produce diversity and various needs in use (for the fourth embodiment of the present application).

[0069] As shown in Fig. 6, the fifth embodiment of the present application can be provided with at least one elastic blocking mechanism 30B at a proper position of the bit accommodating tube 20, which can be designed as a ring in this embodiment. The elastic blocking mechanism 30B has a hollow ring 30B1 and an elastic opening 30B2, and is provided with upper and lower edges 30B3 and 30B4. The bit accommodating tube 20 is provided with a recess 203B at a proper position of the through slot 203, which is larger than the outer diameter of the hollow ring 30B1, so as to provide a space for the elastic blocking mechanism 30B. The elastic blocking mechanism 30B can be made of metal or alloy or high-rigidity metal or alloy or high-rigidity plastic composite, or can be made of magnetic material.

[0070] When the bit 10 is pushed through the inner slot 30B5 of the elastic blocking mechanism 30B and the outer top A1 of the positioning structure 101 of the bit 10, the inner diameter of the inner slot 30B5 is expanded (as shown in the enlarged view of Fig. 6-a). After the bit 10 passes through the elastic blocking mechanism 30B, the elastic blocking mechanism 30B is reset, and the inner diameter of the inner slot 30B5 is reduced A2 to be smaller than the outer diameter of the positioning structure 101 of the bit 10, so as to prevent the bit 10 from being reset (as shown in the enlarged view of Fig. 6-b). The recess 203B3 of the bit accommodating tube 20 and the elastic blocking mechanism 30B constitute a set of elastic blocking mechanisms 30B, which can be provided with one or more sets of elastic blocking mechanisms 30B in the through slot 203 of the bit accommodating tube 20.

[0071] As shown in Fig. 7, the sixth embodiment of the present application can be provided with a guide slope 30B6 in the inner slot 30B5 of one edge 30B3 of the elastic blocking mechanism 30B, which can be used to guide any one of the two ends 102 and 103 of the bit 10, such as an inclined angle or a right angle or any shape, so as to facilitate the use of bits 10 of different specifications and shapes.

[0072] As shown in Fig. 8, it is the seventh embodiment of the present application, and in the above various embodiments, especially in the slot 203 of the end 202 of the bit accommodating tube 20 near the outlet, another elastic holding mechanism 30C is additionally provided. The elastic holding mechanism 30C is the same as the elastic blocking mechanism 30B of the fifth and sixth embodiments in structure, but the purpose is different. The elastic blocking mechanism 30B mainly provides the bit 10 to pass through and prevent the bit 10 from returning, while the elastic holding mechanism 30C is to clamp the bit 10A in the position after passing through the elastic blocking mechanism 30B, so that the locking end 104 of the bit 10 is exposed outside the end 202 of the bit accommodating tube 20 but will not fall off. When the locking end 104 is pressed for use (such as the arrow), it will be prevented from retracting by the elastic blocking mechanism 30B and be used. The material of the elastic holding mechanism 30C is made of metal or alloy or high-rigidity metal or alloy or high-rigidity plastic composite, etc. It can also be made of magnetic material. The annular elastic holding mechanism 30C can be designed with various shapes matching the bit 10 or not, or designed as a closed annular or an open annular.

[0084] As shown in FIGS. 24 and 25, the nineteenth embodiment of the present application is used as an example of the above-mentioned various embodiments, particularly the sixteenth, seventeenth, eighteenth, and nineteenth embodiments of the present application. The plurality of bits 10S each have a convex 1040- concave 104C double locking end 104, which is used as an example. The convex 104- concave 104C double locking end 104 of each bit 10 is stacked in a nested manner with different sizes. (For the rotation of the bit accommodating tube 20 and the bit 10 in the use state, please refer to the description of FIG. 11.) The plurality of bits 10S are stacked in a nested manner with the convex 104 inserted into the concave 104C, and are arranged in order from small to large sizes, or vice versa. Since the bit 10S has a double locking end 104 (or a single locking end 104), the required bit 10 is pushed to the use position at the outlet of one end 202 of the bit accommodating tube 20 in an orderly stacked manner. Since the number of bits 10S stored in the bit accommodating tube 20 is fixed, and the total length of the plurality of bits 10S is also fixed, it is not possible to smoothly push the plurality of bits 10S to the use position if one bit is missing. Therefore, when replacing the bits 10S, the bit to be replaced must be inserted into the slot 203 at one end 201 of the bit accommodating tube 20, so that the locking end 104 of the bit 10 near one end 202 of the bit accommodating tube 20 is pushed to the outlet at one end 202. Therefore, the arrangement order of the bits 10S is not easily confused, and can be provided in an orderly and regular manner. In addition, the double locking end 104 with a convex 104- concave 104C can be used in a reversed manner, with the locking end 104C exposed as a concave end 104C (as shown in FIG. 25).
