- the slide sleeve 14A has its front end formed with an inner sloping annular edge 141 so as to let the combination of the bead(s) 13 with the engaging head member 2 able to be loosened for facilitating removing or replacing the engaging head member 2.
- the fifth conventional tool-combining rod shown in Fig.5 has a slide sleeve 14A provided on the rod member 1 for replacing the engaging head member2 easily, but the outer diameter d1 of the slide sleeve 14A is much larger than the outer diameter d2 of the rod member 1.
- the automatic screwdriver 4 used at the present usually has a screw screwed out and then screwed into an objective, and the automatic screwdriver unit 42 may recover its original position by the recovering resilience of the contractible spring 43.
- the outer annular wall of the tool-combining rod is positioned in a screw bend hole 401 and wrapped by the annular wall of a screw hole 402. If the tool-combining rod is too large, it is hard for the automatic screwdriver tool unit 42 to recover its original position, failing to operate smoothly.
- the tool combining rod employed today has a small outer diameter and is made integral as one 1C, as shown in Figs. 6, 7 and 8, but this integrally made tool combining rod 1C may become unusable and has to be replaced or cast away in case the engage portion 22 of its engaging head member 2 is worn off, increasing cost in using.

Abstract
Description
- This invention relates to a tool-combining rod according to the preamble of
claim 1. Such a tool-combining rod is known from EP-A-0221279. - Conventional tool combining rods are almost the same in structure. One conventional tool-combining rod shown in Figs. 1, 2 and 3 includes a
rod member 1 and anengaging head member 2. Therod member 1 is bored at the front end with a combining hollow 10 have the same shape as that of therod portion 20 of theengaging head member 2 so as to let them combined together closely. The combining hollow 10 is bored with one or twobead holes 12 in itswall 11 for receiving abead 13, which is pressed by asleeve 14, as shown in Figs. 1 and 2. Or the combining hollow 10 may have itswall 11 bored with a C-shaped groove 12A for a C-shaped clasp 13A to be fitted therein, as shown in Fig. 3. Further, between the engagehole 12 and the engagebead 13 or between the C-shaped groove 12A and the C-shaped clasp 13A there must be a space and a little elasticity for theengage bead 13 and the C-shaped clasp 13A to move around in order to permit theengaging head member 2 to be pulled out for replacing and inserted in place with easiness. - A fourth conventional tool combining rod, as shown in Fig. 4, includes a
rod member 1 provided with a combining hollow 10 having ahole 15 in the rear side, and a C-shaped groove 12A in its wall for receiving a C-shaped clasp 16. Thus, in case theengaging head member 2 has to be pulled out or replaced, anauxiliary tool 3 has to be inserted in thehole 15 and pushed the bottom of theengaging head member 2 outward so as to take out or replace theengaging head member 2. - However, each of the four conventional tool combining rods described above needs to be provided with a
bead hole 13 or anannular groove 21 in therod portion 20 of theengaging head member 2 not only to let theengaging head member 2 fixed in position by the bead(s) 13 or the C-shaped clasps shaped clasp bead hole 12 or in the C-shaped groove 12A, thus letting theengaging head member 2 and the combining hollow 10 combined together or disengaged from each other smoothly and easily. - In view of the above-mentioned condition, the thickness L of the
hollow wall 11 has to be set within a proper range. The conventional tool combining rods shown in Figs. 1, 2 and 3 all have too large an outer diameter (over 7 mm) so they are not applicable to anautomatic screwdriver 4 fitted with a screw band, but only available for a common tool having a comparatively short combining rod. The fourth conventional tool-combining rod shown in Fig. 4 has the outer diameter of itsrod member 1 diminished to conform to the foresaid automatic screwdriver. Under this condition, after theengaging head member 2 is combined with the combining hollow 10 of therod member 1, the engaging head member2 is closely stuck by the C-shapedclasp 16 in such a condition that it can hardly be pulled out by hand, and so therod member 1 has to be bored with theside hole 15 for anauxiliary tool 3 to insert therein and prop out theengaging head member 2 by means of an auxiliary tool. However, theside hole 15 bored in the wall of therod member 1 will reduce the strength of therod member 1, possible to render the tool-combiningrod 1 twisted, deformed and broken off at the location of theside hole 15 in the event of the twisting force of combination being too large. - Still the fifth conventional tool-combining rod shown in Fig. 5, includes a
rod portion 1 having a combining hollow 10 in the front end. The combining hollow 10 has itsannular wall 11 bored with anbead hole 12 for receiving abead 13. Acontractible spring 14 is provided on the outer side of thehollow wall 11 of the combining hollow 10, having one end pushing against theannular surface 111 of thehollow wall 11 and the other end pushing against the innerannular surface 140 of aslide sleeve 14A, and positioned between theslide sleeve 14A and thehollow wall 11 of the combining hollow 10. Besides, the combining hollow 10 has its wall provided annularly with a C-shaped clasp 112 to prevent theslide sleeve 14A from slipping off. Theslide sleeve 14A has its front end formed with an inner slopingannular edge 141 so as to let the combination of the bead(s) 13 with theengaging head member 2 able to be loosened for facilitating removing or replacing theengaging head member 2. - As described above, the fifth conventional tool-combining rod shown in Fig.5 has a
slide sleeve 14A provided on therod member 1 for replacing the engaging head member2 easily, but the outer diameter d1 of theslide sleeve 14A is much larger than the outer diameter d2 of therod member 1. As a result, such a tool-combining rod provided with two combining components is not applicable to anautomatic screwdriver 4. In operating, theautomatic screwdriver 4 used at the present usually has a screw screwed out and then screwed into an objective, and theautomatic screwdriver unit 42 may recover its original position by the recovering resilience of thecontractible spring 43. At this time, the outer annular wall of the tool-combining rod is positioned in ascrew bend hole 401 and wrapped by the annular wall of ascrew hole 402. If the tool-combining rod is too large, it is hard for the automaticscrewdriver tool unit 42 to recover its original position, failing to operate smoothly. - Therefore, the tool combining rod employed today has a small outer diameter and is made integral as one 1C, as shown in Figs. 6, 7 and 8, but this integrally made
tool combining rod 1C may become unusable and has to be replaced or cast away in case the engageportion 22 of itsengaging head member 2 is worn off, increasing cost in using. - This invention is devised to offer a tool-combining rod having a small outer diameter (less than 7 mm) and applicable to an automatic screwdriver, able to be operated smoothly and lower cost in manufacturing.
- The present invention has the following features.
- 1. The tool combining rod consists of a rod member having one end formed with a non-round and equiangular portion to be combined with a drive tool for transmitting power, and the other end provided with a combining hollow and having an outer diameter smaller than or equal to the largest outer diameter of foresaid non-round surface, with the combining hollow provided with an inner annular surface for facilitating receiving an engage member.
- 2. The engage member is bored with a central hole for receiving the rod portion of the engaging head member, and provided with an elastic annular surface for combining with the inner annular surface of the combining hollow of the rod member and firmly holding the engaging head member to prevent it from slipping off.
- 3. The tool combining rod is composed of a rod member, an engaging head member and an engage member, therefore in case the engaging head member is worn off due to driving screws, it needs only to replace the engaging head member, reducing expenditure of a user.

- A preferred embodiment of a tool-combining rod in the present invention, as shown in Figs. 9, 10 and 12, includes a
rod member 5, anengaging head member 6 and an engagemember 7 as main components combined together. - The
rod member 5 has a non-circularequiangular portion 55 formed in a rear part, a front hollow 50 formed in a front end and shaped as the shape of arod portion 60 of the engaginghead member 6 and having anannular groove 52 in its wall. The front hollow 50 has an annular taperedsurface 53. And the outer diameter of the non-circularequiangular portion 55 is larger than that of theouter surface 56 of therod member 5. - The engaging
head member 6 has arear rod portion 60 of a geometrical shape with no grooves or recesses and fitting in the front hollow 50 of therod member 5. The engaginghead member 6 further has afront rod portion 61, an engageportion 62 formed in a front end part of thefront rod portion 61, with the outer diameter of therear rod portion 60 is larger than thefront rod portion 61 to define aconical portion 63 therebetween. - The engage
element 7, as shown in Figs. 9, 10, 12 - 15, has anannular wall 70, one ormore slots 71 equidistantly formed in theannular wall 70 so as to supply the engageelement 7 with necessary elasticity for engagement, and its number depends on how large the elasticity or the engaging force is needed. Further arear flange 72 is formed at the rear end of the elasticannular wall 70 to engage with theannular groove 52 of therod member 5, as shown in Fig. 12. Moreover, the engagemember 7 has arear end surface 73 tightly fitting with theconical portion 63 of the engaginghead member 6, so when a user operates anautomatic screwdriver 4, ascrew 41 may produce outward-pulling force against the engaginghead member 6 to prevent the engaginghead member 6 from loosening due to the tight combination of the engagingportion 62 with thefitting groove 410 of thescrew 41 during returning process of theautomatic screwdriver 4. Further, the engagemember 7 has acenter hole 75 and an outerannular surface 74 of any shape so as to be easily clamped by anauxiliary tool 76. And the outerannular surface 74 preferably has a conical shape as shown in Figs. 13 - 15, but can have any shape so long as it cannot stick with a holdingperiphery 402 of ascrew hole 401 of ascrew band 40. Then the engagemember 7 may be easily separated from the engaginghead member 6 with only a little force. - If the engaging
head member 6 is to be altered, it is firstly combined with the engagemember 7, as shown in Fig. 19, and then the two 6 and 7 all together are manually or by means of anauxiliary tool 76 combined with the combining hollow 50 of therod member 5 by means of clamping and pressing the engagemember 7. On the contrary, if the engaginghead member 6 is to be taken out, only engage anauxiliary tool 76 with theouter periphery 74 of the engagemember 7 and pull out the engaginghead member 6 out of therod member 5, as shown in Figs. 20 and 21. - As can be seen, the tool-combining rod in the present invention consists of three components, the
rod member 5, the engaginghead member 6 and the engagemember 7. In order to adapt anautomatic screwdriver 4 with the tool combining rod in the invention, therod member 5 has the non-circularequiangular portion 55, and thesubstantial front portion 56 formed circular or any other shape and having a diameter smaller than or equal to the outer diameter of the rearequiangular portion 55, with the largest diameter of the engagemember 72 being equal to or smaller than that of therod member 5 for convenience of handling theautomatic screwdriver 4. - Next, shown in Figs. 22, 23 and 24, the outer diameter of the engage
member 7 is smaller than the largest outer diameter of therod member 5, so the tool combining rod can easily move ascrew 41 through thescrew hole 401 of thescrew band 40, as shown in Figs. 22 and 23. After thescrew 41 is driven tightly in an object, the tool-combining rod is moved back by the spring 43 (practically amovable member 42 returns to its original position). At this time, the tool-combining rod can move back to its original position through the screw hole 400 of thescrew band 40, without a problem of being constricted dead, impossible to move. Accordingly, a user may use anautomatic screwdriver 4 with the tool-combining rod for driving ascrew 41 smoothly and conveniently. So the tool combining rod may be manufactured with a low cost, not wearing off, splitting or tearing, needless to replace, only with the engaginghead member 6 having to be replaced with a new one in case of the engageportion 62 worn off.
