Screwdriver having a removable ring tab with printed or punched words or diagrams

#The present invention relates to a screwdriver having a removable ring tab on which printed or punched words or diagrams are provided. The screwdriver has a handle portion and a shank portion and on the handle portion is disposed a recessed groove in which the ring tab of a like or different color can be housed. The ends of the ring tab are provided with a retaining protrusion and a retaining cavity respectively for locking the ring tab in place. Words or diagrams of different sized can be printed or punched on the ring tab instead of on the handle portion whereby even mistakenly printed or punched words or diagrams can be easily removed by replacement of the ring tabs without discarding the whole screwdrivers in mass production. Besides, the printed or punched words or diagrams are not easily abraded away in long term operation.

#As shown in FIG. 1, a conventional screwdriver is provided with words or diagrams in 3 ways. The first way is effected by directly printing words 12 on the handle portion 11 of a screwdriver 10; the second way is effected by directly putting embossed words or diagrams 12′ on the handle portion 11 of the screwdriver 10 in an integral production process; the third way is effected by mechanically pressing words or diagrams 12″ on the shank 13 of a screwdriver 10.

#Such prior art screwdrivers have the following disadvantages in practical operation:

#FIG. 1 is a perspective diagram of a prior art screwdriver;

#FIG. 2 is a diagram showing the operation mode thereof;

#FIG. 3 is a perspective diagram of the exploded components of the screwdriver of the present invention;

#Referring to FIG. 3, the screwdriver 20 of the present invention comprises a handle portion 21, a shank portion 22 and a ring tab 30. A peripheral groove 23 of a proper depth is disposed on the handle portion 21. The shape of the ring tab 30 made in conformance to the peripheral groove 23 is resilient and of a color which may be different from the handle portion 21. The ring tab 30 has two split ends, one is a retaining protrusion 31 and the other is a retaining cavity 32.

#As shown in FIG. 4, in assembly, the ring tab 30 printed or punched with words or diagrams of various desired sizes can be registered with the peripheral groove 23 of the screwdriver 20 with the retaining protrusion 31 engaged with the retaining cavity 32 so as to make the ring tab 30 lie flush with the round surface of the handle portion 21 of the screwdriver 20.
