[0028] An end sleeve structure is arranged between the main rod one 1, the plurality of groups of auxiliary rods 2, and the main rod two 3, and is used for mutual butt joint between the main rod one 1, the plurality of groups of auxiliary rods 2, and the main rod two 3.

[0029] A quick disassembly structure is arranged on each group of end sleeve structures between the main rod one 1, the auxiliary rod 2, and the main rod two 3, and is used for assembling any number of groups of auxiliary rods 2 between the main rod one 1 and the main rod two 3 and quickly disassembling the auxiliary rods 2.

[0030] The end sleeve structure comprises a notch sleeve 4, a transverse clamping groove 5, and a clamping protrusion 10, the main rod one 1 and each group of auxiliary rods 2 are fixedly provided with an integrated notch sleeve 4 corresponding to the end in the same direction, the notch sleeve 4 is open, and the transverse clamping groove 5 in the open shape is further arranged on the corresponding center line of the two sides of the notch sleeve 4, the main rod two 3 and each group of auxiliary rods 2 are fixedly provided with an integrated clamping protrusion 10 corresponding to the end on the two sides in the same direction, and the clamping protrusion 10 is matched with the transverse clamping groove 5; the open design of the notch sleeve 4 facilitates the clamping protrusion 10 to be aligned and inserted into the transverse clamping groove 5, which simplifies the butt joint process and improves the convenience of assembly. At the same time, the open structure is convenient for observing the matching of the clamping protrusion 10 and the transverse clamping groove 5 during installation or disassembly; the open design of the transverse clamping groove 5 not only provides a path for the insertion of the clamping protrusion 10, but also plays a role in limiting the clamping protrusion 10 in the transverse direction after clamping, so as to ensure that the main rod one 1, the auxiliary rod 2, and the main rod two 3 will not relatively displace in the transverse direction after butt joint, thereby enhancing the stability of the connection.

[0031] The ends of the main rod two 3 and each group of auxiliary rods 2 are sequentially inserted into the notch sleeves 4 on the ends of each group of auxiliary rods 2 and the main rod one 1 in the same direction, and the clamping protrusions 10 on the two sides of the ends of the main rod two 3 and the auxiliary rod 2 are clamped into the transverse clamping grooves 5 arranged on the two sides of each group of notch sleeves 4.

[0032] The quick dismounting structure comprises the circular arc clamping plate 7, the limiting circular arc groove 8, the limiting circular arc strip 9 and the clamping plate gap 11, the upper and lower sides of the gap sleeve 4 corresponding to the horizontal clamping groove 5 are provided with the circular arc grooves 6, the upper and lower sides of the gap sleeve 4 are symmetrical to each other, and the two ends of the circular arc grooves 6 are open to the inner wall of the horizontal clamping groove 5, the upper and lower sides of the gap sleeve 4 are slidably clamped with the circular arc clamping plate 7, the arc length of the circular arc clamping plate 7 is less than the opening arc length of the circular arc groove 6, the two sides of the gap sleeve 4 corresponding to the circular arc groove 6 are provided with the limiting circular arc grooves 8, and the two sides of the circular arc clamping plate 7 are integrally and slidably clamped in the limiting circular arc grooves 8, and the ports of the limiting circular arc grooves 8 are also open to the ports of the circular arc grooves 6, and the cooperation of the limiting circular arc grooves 8 and the limiting circular arc strips 9 limits and guides the circular arc clamping plate 7. On the one hand, the limiting circular arc strip 9 slides in the limiting circular arc groove 8, so that the circular arc clamping plate 7 can only move on a specific track, thereby ensuring the accuracy of the clamping and disengaging clamping actions; on the other hand, the cooperation also prevents the circular arc clamping plate 7 from being pulled out of the circular arc groove 6 during operation, thereby ensuring the reliability of the quick dismounting structure, the clamping protrusion 10 is provided with the clamping plate gap 11 corresponding to the port of the circular arc groove 6, thereby providing a channel for the clamping of the circular arc clamping plate 7, and the circular arc clamping plate 7 can be rotated and clamped in the clamping plate gap 11 provided in the clamping protrusion 10.

[0033] The thickness of the clamping protrusion 10 is greater than the thickness of the gap sleeve 4, so that a part of the clamping protrusion 10 protrudes out of the gap sleeve 4 after being inserted into the horizontal clamping groove 5, thereby providing a structural basis for the subsequent clamping of the circular arc clamping plate 7, and the side outer wall of the clamping protrusion 10 corresponding to the clamping plate gap 11 is open, the outer surface of the circular arc clamping plate 7 protrudes out of the outer surface of the gap sleeve 4, thereby facilitating the operator to directly operate the circular arc clamping plate 7 for rotation, and improving the convenience of operation.

[0034] The clamping protrusion 10 is provided with the gap 12 corresponding to the two side inner walls of the clamping plate gap 11, and the two side gaps 12 in the clamping plate gap 11 are aligned with the upper and lower limiting circular arc grooves 8 in the circular arc groove 6, so that the limiting circular arc strips 9 on the two sides of the circular arc clamping plate 7 can smoothly pass through during the clamping rotation, thereby avoiding interference and ensuring smooth clamping action.

[0035] Working principle: according to the operation requirement, the length of the screwdriver rod can be adjusted, and the main rod one 1 and the main rod two 3 can be directly connected:

[0036] The clamping protrusions 10 on both sides of the end of the main bit bar two 3 are aligned with the horizontal clamping grooves 5 on both sides of the notch sleeve 4 on the end of the main bit bar one 1, then the main bit bar two 3 is inserted into the notch sleeve 4 until the clamping protrusions 10 are completely clamped into the horizontal clamping grooves 5. Then, the circular arc clamping plate 7 is rotated, and since the limiting circular arc strips 9 on both sides of the circular arc clamping plate 7 can slide in the limiting circular arc grooves 8, the circular arc clamping plate 7 can be smoothly rotated. When the circular arc clamping plate 7 is rotated to a certain angle, it is made to penetrate and clamp into the clamping plate notches 11 provided in the clamping protrusions 10, and the blocking effect of the circular arc clamping plate 7 prevents the main bit bar two 3 from being pulled out of the notch sleeve 4 of the main bit bar one 1, thereby completing the connection of the main bit bar one 1 and the main bit bar two 3.

[0037] According to the operation requirements, the length of the screwdriver bar is adjusted, and any number of groups of the auxiliary bit bars 2 are disassembled and assembled.

[0038] The auxiliary bit bar 2 is installed: the clamping protrusions 10 on both sides of the end of the auxiliary bit bar 2 are aligned with the horizontal clamping grooves 5 on both sides of the notch sleeve 4 on the end of the previous bar, which can be the main bit bar one 1 or the auxiliary bit bar 2 that has been installed, and the auxiliary bit bar 2 is inserted so that the clamping protrusions 10 are clamped into the horizontal clamping grooves 5. Then, the circular arc clamping plate 7 on the notch sleeve 4 is rotated so that it penetrates and clamps into the clamping plate notches 11 of the clamping protrusions 10 of the auxiliary bit bar 2, thereby completing the installation of one group of auxiliary bit bars 2. By repeating this operation, multiple groups of auxiliary bit bars 2 can be installed according to requirements.

[0039] The auxiliary bit bar 2 is disassembled: the circular arc clamping plate 7 is reversely rotated so that it is separated from the clamping plate notches 11 of the clamping protrusions 10, and since the limiting circular arc strips 9 are limited in the limiting circular arc grooves 8, the circular arc clamping plate 7 will not be separated from the notch sleeve 4. Then, the auxiliary bit bar 2 is pulled out of the notch sleeve 4, and the disassembly is completed. By repeating this operation, any number of auxiliary bit bars 2 can be disassembled, and the length of the screwdriver bar can be adjusted.

[0040] Through the cooperation of the above-mentioned end sleeve structure and quick disassembly and assembly structure, the combined segmented screwdriver bar can quickly connect the main bit bar one 1 and the main bit bar two 3, and conveniently and quickly install or disassemble the auxiliary bit bar 2 according to operation requirements, so that the length of the screwdriver bar can be flexibly adjusted to adapt to operation requirements of different depths or spaces.

[0041] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
