Description
本發明係與快速拆卸裝置有關，詳而言之，係指一種工具頭快速拆卸裝置。 The present invention relates to a quick disassembly device, and more particularly to a tool head quick dismounting device.
按，近代工業發展迅速，不只是專業技師們，一般社會大眾對於手工具之利用已是稀鬆平常的事情，其中，可快速拆卸工具頭之手工具因具有使用便捷及攜帶方便等特性，已廣泛使用於各種類型之工作環境。 According to the rapid development of modern industry, not only professional technicians, but the general public's use of hand tools is a common problem. Among them, the tool for quick disassembly of the tool head has been widely used because of its convenient use and portability. Used in all types of work environments.
習知之一種可快速拆卸工具頭之手工具結構，如第M428023號發明專利所示，請參閱第一圖，其所提供之拆卸裝置10包含有一套接筒12、一按壓構件16及一工具頭17。該套接筒12內具有一套接空間13，並於該套接空間13之內壁面環設有一定位環圈14。該按壓構件16之底端具有一磁性物件161，並係穿設於該套接筒12之頂面，可沿該套接筒12之軸向上下位移。該工具頭17之周側壁設有可供定位之多數凹槽18。如此，當該工具頭17套接於該套接筒12之套接空間13時，其頂端係受到該磁性物件161的吸固，其周側壁之該等凹槽18係卡固於該套接空間13之定位環圈14，而可使該工具頭17不會滑動鬆脫。請參閱第二圖，當欲拆卸該工具頭17時，係按壓該按壓構件16之頂端，使該工具頭17之凹槽18脫離該套接空間13之定位環圈14，再將該工具頭17向下拉引，使該工具頭17之頂端脫離該磁 性物件161之吸固，而可將該工具頭17取出，以便進行後續之工具頭之替換作業。 A hand tool structure for quickly disassembling a tool head, as shown in the invention patent No. M428023, please refer to the first figure. The disassembling device 10 provided includes a set of the barrel 12, a pressing member 16 and a tool head. 17. The socket 12 has a set of connecting spaces 13 , and a positioning ring 14 is disposed on the inner wall of the socket space 13 . The bottom end of the pressing member 16 has a magnetic member 161 and is disposed on the top surface of the sleeve 12 and is vertically displaceable along the axial direction of the sleeve 12. The peripheral side wall of the tool head 17 is provided with a plurality of recesses 18 for positioning. Thus, when the tool head 17 is sleeved in the socket space 13 of the socket 12, the top end of the sleeve is received by the magnetic object 161, and the grooves 18 of the peripheral side wall are fastened to the socket. The positioning ring 14 of the space 13 allows the tool head 17 to be prevented from sliding loose. Referring to the second figure, when the tool head 17 is to be removed, the top end of the pressing member 16 is pressed, so that the groove 18 of the tool head 17 is disengaged from the positioning ring 14 of the socket space 13, and the tool head is replaced. 17 pull down to make the top of the tool head 17 out of the magnetic The article 161 is wicked and the tool head 17 can be removed for subsequent tool head replacement.
然而，上述之工具頭之拆卸裝置10於使用上有所缺失，如當按壓該按壓構件16之頂端以將該工具頭17推出該套接空間13時，由於該磁性物件161係設於該按壓構件16之底端，即便該工具頭17之凹槽18脫離該套接空間13之定位環圈14，該工具頭17仍被吸固於該按壓構件16之底端，無法脫離該套接空間13，使用者必須再將該工具頭17向下拉引才可將該工具頭17自該套接空間13內脫出，使拆卸裝置10之實用性大打折扣。 However, the above-mentioned tool head dismounting device 10 is missing in use, such as when the top end of the pressing member 16 is pressed to push the tool head 17 out of the socket space 13, since the magnetic object 161 is attached to the pressing. At the bottom end of the member 16, even if the recess 18 of the tool head 17 is disengaged from the positioning ring 14 of the socket space 13, the tool head 17 is still sucked to the bottom end of the pressing member 16, and cannot be separated from the socket space. 13. The user must pull the tool head 17 downward to release the tool head 17 from the socket space 13, so that the utility of the disassembly device 10 is greatly reduced.
其次，以該按壓構件16將該工具頭17推出該套接空間13時，由於該定位環圈14係為彈性物件，即便該工具頭17之凹槽18脫離該定位環圈14，該定位環圈14仍會束縛該工具頭17之周壁，如第二圖所示，使該工具頭17無法直接脫出該套經空間13，如此不僅喪失快速拆卸之效果，使用上亦十分繁瑣且不便。 Secondly, when the pressing member 16 pushes the tool head 17 out of the socket space 13, since the positioning ring 14 is an elastic member, even if the groove 18 of the tool head 17 is separated from the positioning ring 14, the positioning ring The ring 14 still restrains the peripheral wall of the tool head 17, as shown in the second figure, so that the tool head 17 cannot directly escape the sleeve space 13, so that not only the effect of quick disassembly is lost, but also the use is cumbersome and inconvenient.
本發明旨於解決上揭缺失，其主要目的在於提供一種快速拆卸裝置，其可快速拆卸工具頭，提升使用時的實用性與便捷性。 The present invention is directed to solving the above-mentioned problems, and its main object is to provide a quick disassembly device which can quickly disassemble the tool head and improve the practicability and convenience in use.
