The working end 31 is formed in a shape of a cross, a cross, and a sixth An angled, ratchet-shaped or plum-shaped shape, etc., the positioning rod 32 is provided with a positioning block 32, and one side of the positioning block 32 is provided with a convex body 33, and the convex body 33 is attached to the fixing collar 2, the convex body 33 is provided with a ring groove 34. The assembly block 11 corresponding to the handle 1 in the convex body 33 is provided with a polygonal insertion groove 35, and the insertion groove 35 is set to be associated with the group. Block 11 is matched Each of the positioning inlays 21 corresponding to the fixing collar 2 is provided with a guiding groove 36 on the outer wall surface of the protruding body 33. The guiding grooves 36 are connected to the annular groove 34, so that the replacement is a replacement. Screwdriver structure.

When assembling, please refer to the first to fourth figures. First, the fixing collar 2 is sleeved on the connecting block 11 of the handle 1, so that the positioning flange 20 in the fixing collar 2 is embedded in the assembling block 11 In the upper ring groove 12, the fixing collar 2 is fixed on the assembly block 11 of the handle 1, and the fixing collar 2 can be rotated on the assembly block 11, and then the driver shaft 3 to be used is selected. The insertion end 30 of the driver shaft 3 is inserted into the fixing collar 2 and the insertion hole 10 of the handle 1. The positioning inlay 21 in the fixing collar 2 is along the driver shaft 3. The guiding groove 36 on the convex body 33 is slid into the annular groove 34, and the assembling block 11 of the handle 1 is inserted into the insertion groove 35 of the convex body 33 of the screwdriver shaft 3, and the fixing sleeve is inserted. The ring 2 is rotated by an angle, so that the positioning inlay 21 on the fixing collar 2 is rotated and disengaged from the guiding groove 36 to be embedded in the ring groove 34. The driver rod body 3 can be fixed by the fixing collar 2 On the handle 1, so that the overall assembly can be completed, and the assembly is very convenient and fast.

When using, please refer to the first to fourth figures, the user only needs to select the driver shaft 31 which has the same shape as the screw head groove of the screw or the screw to be loosened, and the driver shaft 3 is selected. It can be used by being inserted into the handle 1 in the above assembled manner. If the driver shaft 3 is to be replaced, the fixed collar 2 only needs to be rotated in the reverse direction, so that the positioning inlay 21 in the fixing collar 2 is in the ring groove. 34 is internally rotated and the guide groove 36 on the convex body 33 of the screwdriver shaft 3, the positioning inlay 21 of the fixing collar 2 is no longer embedded in the ring groove 34 of the driver shaft 3, and The driver rod body 3 is pulled out and replaced from the handle 1 so that various types and sizes of the driver rod body 3 can be easily and quickly replaced on the single handle 1, which can reduce the space for the screwdriver to be placed. Carrying and using, and saving the cost of purchasing a plurality of screwdrivers; and the present invention can be increased by the polygonal combination block 11 on the handle 1 and the polygonal insertion groove 35 in the convex body 33 of the driver shaft 3 The strength of the overall assembly.

In view of the above, the present invention has achieved the intended use and efficacy, and is more desirable and practical than the prior art, but the above embodiments are only specifically described for the preferred embodiment of the present invention.
