The guide rail 9 and the limit cover 5 jointly limit a guide groove, and the plate body 81 is slidably assembled in the guide groove and adapted to the guide groove size. By setting the guide rail 9 to form a guide groove, it is convenient to constrain the moving direction of the plate body 81, and at the same time limit the axial movement of the plate body 81 in the rod body 1, to ensure that when the limit groove 811 of the plate body 81 is engaged with the limit ring groove 33 of the screwdriver 3, the plate body 81 and the screwdriver 3 are blocked in the axial direction of the rod body 1.

[0058] Optionally, the guide rail 9 is L-shaped and two guide rails are provided, and the two guide rails 9 and the bottom wall of the limiting cover 5 jointly limit a guide groove.

[0059] It should be noted that, when the limit cover 5 is rotated and the first screwdriver 3 corresponding to the through hole 51 is not the required one, the screwdriver 3 will, under the action of the support spring, make the cutter head 31 partially extend into the through hole 51 and cooperate with the plate body 81 for blocking. At this time, the thickness of the cover plate corresponding to the through hole 51 on the limit cover 5 can be ignored, or the through hole 51 is a conical hole whose cross-sectional diameter decreases in the direction approaching the plate body 81. When the limit cover 5 is rotated, the cutter head 31 can slide along the conical surface and move in the direction away from the plate body 81, so that the limit cover 5 will not be stopped by the through hole 51 and the cutter head 31 when it is rotated.

[0060] In some embodiments, Figure 7 As shown, a first extension plate 82 is provided at one end of the plate body 81 close to the through hole 51, and a second extension plate 83 is provided at one end of the plate body 81 away from the through hole 51.

[0061] Specifically, two first extension plates 82 are provided at one end of the plate body 81 close to the through hole 51, and the two first extension plates 82 are provided on both sides of the plate body 81, and the extension direction of the first extension plate 82 is perpendicular to the axial direction of the rod body 1, and at the same time, the first extension plate 82 is prevented from interfering with the limiting ring groove 33, so as to ensure the clamping fit between the plate body 81 and the connecting rod 32 of the screwdriver 3. When a limiting spring is provided between the first extension plate 82 and the guide rail 9, the limiting spring is a supporting spring. Under the action of external force, the limiting spring is used to push the first extension plate 82 to move away from the guide rail 9 to drive the plate body 81 to move. When the second extension plate 83 When a limit spring is provided between the guide rail 9, the limit spring is a tension spring. Under the action of external force, the limit spring is used to drive the second extension plate 83 to move in the direction close to the guide rail 9 to drive the plate body 81 to move. The limit spring is provided. When the screwdriver 3 does not extend out of the mounting hole 12 and the through hole 51, the plate body 81 can block the through hole 51, so as to facilitate the rotation of the limit cover 5 to select a suitable screwdriver 3. When the screwdriver 3 extends out of the mounting hole 12 and the through hole 51, the plate body 81 is snap-fitted with the screwdriver 3. The limit spring can prevent the plate body 81 from contacting with the screwdriver 3 by snap-fitting, thereby ensuring the reliability of the screwdriver 3 when in use.
