Abstract

A universal joint with a changeable tool component comprises a female boss and a tool component. A nesting part and an accommodating part are respectively arranged at the two ends of the female boss; a sphere and a drive part are respectively arranged at the two ends of the tool component; the sphere is arranged in the accommodating part of the female boss; a brake structure is arranged between the accommodating part of the female boss and the sphere of the tool component, so that a female boss is clamped to drive the tool component to rotate synchronously; besides, a lock-out structure is arranged on the female boss; slotted holes communicated with the accommodating part are formed on the two sides of the lock-out structure of the female boss; a buckle piece is arranged in each slotted hole; a pressing sleeve with a butt-pulling surface inside is sleeved on the outer side of the female boss; the pressing sleeve pushes the two buckle pieces to clamp the sphere via the butt-pulling surface, so as to assemble the tool component on the female boss; therefore, only by operating the pressing sleeve of the female boss to enable the buckle piece to be separated from the tool component, tool components with different types and sizes of drive parts can be assembled on a single female boss, therefore, the purposes of great cost saving and portability are achieved.

Description

The universal joint of replaceable different tool assemblies

Technical field

The utility model relates to a kind of universal joint, be particularly related to a kind of universal joint of replaceable different tool assemblies, this utility model can make female seat and tool assembly rotate synchronously, and with the single female seat different tool assemblies of arranging in pairs or groups, thereby significantly saves cost and be easy to carry.

Background technology

Can arrange in pairs or groups hand-held tool or pneumatic tool of universal joint carried out the operation of mounting or dismounting bolt tool, yet bolt tool according to different types and size, each universal joint also is provided with different types, the tool assembly of size, the universal joint that for example has the sleeve barrel tool assembly, have the universal joint of die nut tool assembly or have universal joint of screwdriver head tool assembly etc., and the tool assembly of same pattern roughly is divided into public affairs, imperial sizing, with the universal joint with sleeve barrel tool assembly is example, differentiation has a plurality of universal joints of a series of different imperial sizing sleeve barrel tool assemblies, and a plurality of universal joints of a series of different metric size sleeve barrel tool assemblies.

See also Fig. 1, be No. 87218189 " structural improvement of universal sleeve (appending one) " patent case of TaiWan, China patent, this universal sleeve 10 includes tool assembly 11 and female seat 12, this tool assembly 11 is provided with the drive division 111 that is quadrangular prism and has steel ball in an end, the other end then is provided with the spheroid 112 with perforation 113, one end of this female seat 12 is provided with the fit portion 121 that is four jiaos of holes, in order to socket hand-held tool or pneumatic tool, the other end of female seat 12 then is provided with the holding part 122 of built-in spring 123, and offer two corresponding and connect through hole 124 to holding part 122, and can insert the spheroid 112 of tool assembly 11 in the holding part 122 of female seat 12, utilize alignment pin 13 to run through the perforation 113 of the through hole 124 and the tool assembly 11 of female seat 12 again, tool assembly 11 fixedly is assembled on the female seat 12, in addition be equipped with spring 14 and have the ring set 15 of projection 151 in the outer cover of female seat 12, this ring set 15 convexes with one and coats edge 152 in the top of projection 151, buckleing 16 with a C type again is buckled on the female seat 12, and be positioned at coating edge 152 sides of ring set 15, and can be with the spacing in case anti-avulsion of ring set 15 clips from female seat 12; Yet this universal sleeve has following disappearance:

Though the ring set 15 of this universal sleeve 10 can utilize and coat edge 152 and prevent that the C type from buckleing 16 impaired, and when pressing down ring set 15, replaceable C type buckles 16, but the spheroid 112 of tool assembly 11 is fixedly to be assembled in the holding part 122 of female seat 12 with alignment pin 13, when tool assembly 11 damages, owing to can't change tool assembly 11 separately, so that whole universal sleeve 10 must be abandoned, cause the disappearance that expends cost.

Because a female seat 12 sets firmly the tool assembly 11 of assembling unimodality and size, if desire is produced the universal sleeve 10 of ten kinds of a series of different metric sizes, promptly must make ten tool assemblies 11 and ten female seats 12, when producing the universal sleeve 10 of different types (the universal sleeve that for example has the screwdriver head tool assembly), must make the tool assembly 11 and the female seat 12 of a series of relative populations in addition again, so that quite expend cost in the making of universal sleeve 10.

Because universal sleeve 10 is metallic articles, and the universal sleeve 10 of each of different types, size all disposes a tool assembly 12 and female seat 11, when the user desires to carry the universal sleeve 10 of a plurality of different types, size, the burden that the weight of a plurality of female seats 12 is carried increase causes the shortcoming of carrying effort.

Therefore, how to design a kind of tool assembly of different types, size that can on female seat, change the outfit, and significantly save cost and the convenient universal joint that carries, be the target of these relevant practitioner's research and development.

Summary of the invention
