The central shaft 20 has a fixed end 201 and a limiting end 202, with a first annular groove 203 formed near the fixed end 201 and a second annular groove 204 formed near the limiting end 202.If the insulating body 11 of the handle 10 is arranged such that it simultaneously encloses the drive element 12 and the fixed end 201 of the central axis 20, the central axis 20 remains stably positioned inside the handle 10, and the drive element 12 and the central axis 20 are separated from each other, thus completely isolating the central axis 20 and the handle 10 and ensuring safe use of the insulated tool. The storage unit 30 has a sheath tube 31 and an elastic ring 32, with a storage holder 33 and a locking plate 34 arranged on the sheath tube 31, the storage holder 33 serving to hold the at least one bit 40. A plurality of elastic grippers 311 are arranged at one end of the sheath tube 31, and the other end is connected to an end cap 35.The outer tube 31 is inserted over the central axis 20 in such a way that it is slidable along the central axis 20. By bringing the elastic grippers 311 into engagement in the first annular groove 203 or in the second annular groove 204 and then holding them with the elastic ring 32, the outer tube 31 can be completely fixed at the point where it has traveled the greatest distance. On the side of the inner tube part 312 of the outer tube 31 facing the elastic grippers 311, a stepped edge 313 is arranged, and a locking sleeve 21 is mounted on the limiting end 202 of the central axis 20, wherein the outer diameter of the locking sleeve 21 is larger than the diameter of the stepped edge 313 and smaller than the diameter of the inner tube part 312, so that the outer tube 31 can be blocked by the locking sleeve 21 so that it does not immediately detach from the central axis 20 when moved.Once the outer tube 31, together with the storage holder 33, the locking plate 34 and at least one bit 40, is completely installed inside the handle 10, the open end 102 of the handle 10 is closed with the end cap 35.

[0013] According to the invention, the insulating body 11 is designed in such a polygonal shape that the insulating body 11 and the actuating end 101 of the handle 10 are positively locked together.

[0014] According to the invention, a slot 111 is formed on the insulating body 11, into which the actuating end 101 of the handle 10 can be inserted.

[0015] According to the invention, the drive element 12 is a ratchet socket wrench insert.

[0016] According to the invention, the drive element 12 is a conventional socket wrench insert.

[0017] According to the invention, an extended part 121 is arranged on the drive element 12, which serves to ensure that the drive element 12 is surrounded over a large area by the insulating body 11.

[0018] According to the invention, a groove 2011 is formed at the fixed end 201 of the central axis 20, into which the insulating body 11 is inserted as soon as the insulating body 11 surrounds the drive element and the fixed end of the central axis.

[0019] According to the invention, a barrier wall 112 is formed between the drive element 12 and the stationary end 201 as soon as the insulating body 11 encloses the drive element 12 and the stationary end 201 of the central axis 20. Thus, the drive element 12 and the stationary end 201 can be completely separated from each other by the barrier wall 112.

[0020] For the use of the insulated tool according to the invention, the following applies: Fig. 5 to Fig.Reference is made to Figure 7. By pulling the end cap 35, the storage holder 33, together with the bit 40, is pulled out of the end cap 35 and the outer tube 31 is pulled out of the handle 10. Simultaneously, the elastic grippers 311 are removed from the first annular groove 203 and instead moved to engage in the second annular groove 204, so that the outer tube 31, together with the storage holder 33, is securely fixed in a position in which the outer tube 31 and the storage holder 33 are exposed, allowing the at least one bit 40 to be taken or replaced. Once the at least one bit 40 has been taken or replaced, the end cap 35 and the outer tube 31 are pushed back in the opposite direction. Thus, the open end 102 is closed again with the end cap 35. The screwdriver is then ready for the next use.

[0021] The insulated tool according to the invention, with an arrangement for storing bits, has the following advantages. First, the elastic ring 32 is inexpensive to manufacture and easier to assemble, thus making the arrangement for storing bits equipped with the elastic ring 32 more competitive. Second, the elastic ring 32 is designed to hold the elastic grippers 311 in such a way that they are reliably held in the position in which the elastic grippers 311 engage with the first annular groove 203 or the second annular groove 204, thereby ensuring reliable fixation of the components of the insulated tool.Thirdly, the insulated tool is designed such that the central axis 20 is enclosed by the insulating body 10 in such a way that the central axis 20 and the drive element 12 are separated from each other, so that the drive element 12 and the central axis 20 do not come into direct contact, thereby ensuring absolute isolation when using the insulated tool, so that the user is well protected when using the insulated tool according to the invention with electrical equipment.
