The screwdriver includes a connector (10, Figure 3), a shank 1 with a handle 11 connected to a rotatable collar 2 and a base 3 located in a polygonal cavity 17 of the handle. At least one resilient member (22, Figure 3) extends from the underside of the collar and is inserted in a recess (15, Figure 3) of the handle. A stop (23, Figure 6) also extends from the underside of the collar and is located in a cut 14 of a ridge 13 of the handle. At least one notch 24 and at least one block 25 are formed on the top end of the collar. An annular groove (26, Figure 3) on the collar engages with a flange 16 on the handle. The base is connected to the top end of the collar via a polygonal reception member 30 located in the handle cavity. A tube (31, Figure 4) extends from the base which secures a rod 36 connected to a positioning member 37. The positioning member includes multiple slots 371 able to hold bits 4 in position. The end of the base is sealed by a cap 38. |
