Detailed Description

Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1-4, the utility model provides a screwdriver with a replaceable tool bit, which comprises a fixed rod 1 and a fixed handle 101, wherein a fixed block 2 is penetrated inside the fixed rod 1, a rotating rod 3 is sleeved on the surface of the fixed block 2, a sleeve joint 4 is arranged on the surface of the rotating rod 3, a rubber ring 5 is connected on the surface of the sleeve joint 4, thread grooves 6 are formed inside the fixed rod 1, the rotating rod 3 and the rubber ring 5, and a threaded rod 7 is connected inside the thread grooves 6 in a threaded manner.

The fixed rod 1 and the rotating rod 3 are in a clamping structure and are sleeved on the surface of the fixed block 2; the fixed block 2 connects the fixed rod 1 with the rotating rod 3, so that the rotating rod 3 can rotate.

The rubber ring 5 is positioned between the sleeve joint 4 and the fixed block 2; the rubber ring 5 can increase friction and limit the rotation amplitude of the rotating rod 3.

The thread groove 6 is matched with the threaded rod 7 in size and is symmetrical with respect to the longitudinal center line of the fixed block 2; the threaded rods 7 on two sides fixedly mount the fixed rod 1 and the rotating rod 3, and limit the rotation of the rotating rod 3.
