Description
本發明係與鑽頭工具有關，特別是關於一種連接於起子頭的替換式鑽頭工具。The present invention is related to bit tools, and more particularly to an alternative bit tool attached to a bit.
按，一般欲以電動工具裝設起子頭進行鎖固螺絲動作時，大都會預先以工作物上先鑽設一組裝孔，以便螺絲可順利螺結鎖固，然而由於電動工具一次只能夾持一種工具(鑽頭或起子頭)，因此作業人員需時常進行鑽頭或起子頭的拆換動作，造成作業上極大的不便。Press, when you want to use the power tool to install the screwdriver head to lock the screw action, the Metropolis first drills an assembly hole on the work object so that the screw can be screwed smoothly, but the power tool can only be clamped at a time. A tool (drill bit or screwdriver head), so the operator needs to perform the action of removing the drill bit or the screwdriver head from time to time, resulting in great inconvenience in operation.
是以，証書號M265168，如圖1所示，其揭露一套筒1，該套筒1一端套接起子頭，該起子頭組設於電動工具上(圖未示)，該套筒1一端具有一彈性夾頭18，另一端具有一定位單元2；一鎖緊螺帽3係螺接於彈性夾頭18外部，以及一鑽頭4，該鑽頭4係插置在套筒1內，轉動該鎖緊螺帽3壓迫該彈性夾頭18，以夾緊該鑽頭4，利用該鑽頭4於工作物上鑽設好組裝孔後，將該套筒1與該起子頭分離，即可藉由該電動工具連接起子頭將螺絲螺鎖於組裝孔。Therefore, the certificate number M265168, as shown in FIG. 1, discloses a sleeve 1 which is sleeved at one end with a screwdriver head. The screwdriver head is assembled on a power tool (not shown), and the sleeve 1 is provided at one end. The utility model has a resilient collet 18 with a positioning unit 2 at the other end; a locking nut 3 is screwed to the outside of the elastic collet 18, and a drill bit 4 is inserted into the sleeve 1 to rotate the The locking nut 3 presses the elastic collet 18 to clamp the drill bit 4, and after the drill hole 4 is drilled into the working hole, the sleeve 1 is separated from the screwdriver head, thereby The power tool is connected to the driver's head to screw the screw to the assembly hole.
上述習知專利雖可解決需拆換鑽頭、起子頭的問題，但實際使用上因為需利用該鎖緊螺帽3螺接於該彈性夾頭18，才能迫緊該彈性夾頭18夾緊該鑽頭4，因此鎖緊螺帽3的尺寸必需與該彈性夾頭18相符，除此鑽頭的尺寸亦會受到該鑽緊螺帽3的限制，換言之如欲更換較粗的鑽頭時原先的鎖緊螺帽3則無法使用，因此整體在使用上並不便利。Although the above-mentioned conventional patent can solve the problem that the drill bit and the screwdriver bit need to be dismantled, in actual use, since the lock nut 3 needs to be screwed to the elastic collet 18, the elastic collet 18 can be forced to clamp. The drill bit 4, therefore, the size of the locking nut 3 must conform to the elastic collet 18, except that the size of the drill bit is also limited by the tightening nut 3, in other words, the original locking when the thicker drill bit is to be replaced The nut 3 cannot be used, so the overall use is not convenient.
以及，証書號M296114，如圖2所示，其揭露一套筒5、一鎖結元件6及一固定裝置7，該套筒5前端設置一具螺孔8之夾持部9，該夾持部9供一鑽頭插設，藉該鎖結元件6螺鎖於該夾持部9之螺孔8迫抵鑽頭柄部固定，固定裝置7係由一活動束筒70、一彈簧71、一鋼珠72及一扣環73所組成，該固定裝置7組設於該套筒5後段。And the certificate number M296114, as shown in FIG. 2, discloses a sleeve 5, a locking component 6 and a fixing device 7. The front end of the sleeve 5 is provided with a clamping portion 9 with a screw hole 8, the clamping The portion 9 is inserted into a drill bit, and the screw hole 8 of the clamping portion 9 is screwed to the shank of the shank portion. The fixing device 7 is composed of a movable beam tube 70, a spring 71, and a steel ball. 72 and a buckle 73 are formed, and the fixing device 7 is assembled in the rear portion of the sleeve 5.
上述習知專利雖可達到快速套接於預先夾持在電鑽的起子頭上，藉由起子頭帶動鑽頭進行鑽孔動作，及於鑽孔後方便拆卸下起子頭進行鎖固螺絲；惟整體組裝方式過於複雜，以及固定裝置7的構件亦過於繁雜，除此如欲更換言鑽頭時，則必需額外使用工具採能將鎖結元件6拆卸，使該鎖結元件6分離原先迫抵之鑽頭柄部，因此不僅使用成本提高，且操作上極為不易。Although the above-mentioned conventional patent can be quickly sleeved on the screwdriver head pre-clamped on the electric drill, the drill bit is driven by the screwdriver head, and the screwdriver is easily removed after drilling, and the overall assembly method is too The complexity, as well as the components of the fixing device 7, are also too complicated, in addition to the replacement of the drill bit, it is necessary to additionally use the tool to disassemble the locking element 6, so that the locking element 6 is separated from the original handle of the bit. Therefore, not only is the use cost increased, but the operation is extremely difficult.
因此，如何改善習知產品的缺失即為本發明目前首要研發課題。Therefore, how to improve the lack of conventional products is the current primary research and development topic of the present invention.

The clip hole 111 is worn out.
進一步說明本發明的操作方式如下：Further explaining the operation of the present invention is as follows:
本發明之連接件20係分別藉由兩端的六角形套接孔21及外螺紋段24分別套接於一起子頭40(為六角形狀)及螺鎖於該夾頭10，且該起子頭40在套入該連接件20之六角形套接孔21內時，係藉由該固定環30性抵壓住該定位件23，該定位件23抵壓住該起子頭40，防止起子頭40脫落；以及該起子頭40夾持於一電動工具50上，而該夾頭10則係藉由該彈性夾緊單元12穿出該夾孔111並夾持一鑽頭60，據此組設成本發明之替換式鑽頭工具，利用該鑽頭60於一加工物上鑽設好組裝孔(圖未示)，再將該連接件20脫離與該起子頭40的套接關係，即可利用該電動工具50所夾持之起子頭40將螺絲螺鎖於該組裝孔內；The connecting member 20 of the present invention is respectively sleeved to the sub-head 40 (which is hexagonal) and screwed to the collet 10 by the hexagonal sleeve hole 21 and the external thread segment 24 at both ends, respectively, and the screwdriver head 40 When the sleeve is inserted into the hexagonal sleeve hole 21 of the connecting member 20, the positioning member 23 is pressed against the fixing member 30, and the positioning member 23 presses against the driver head 40 to prevent the driver head 40 from falling off. And the screwdriver head 40 is clamped to a power tool 50, and the chuck 10 is passed through the clamping hole 111 by the elastic clamping unit 12 and clamps a drill bit 60, according to which the invention is assembled. The replacement drill tool uses the drill bit 60 to drill an assembly hole (not shown) on a workpiece, and then the connector 20 is disengaged from the driver head 40, and the power tool 50 can be utilized. The clamped screwdriver head 40 screws the screw into the assembly hole;
而本發明具有操作簡單及快速拆換之特點，係藉由該連接件20以螺轉的方式螺入該第二本體14並與該推片13接觸，如欲使該夾頭10之彈性夾緊單元12完全夾緊該鑽頭60，則將該連接件20持續螺旋並推壓該推片13，帶動該推片13同步推壓該彈性夾緊單元12，使該彈性夾緊單元12因受該推片13的推壓於該第一本體11之容置空間110內往該夾孔111方向移動並穿出該夾孔111，且當該彈性夾緊單元12愈往該夾孔111方向移動時則愈夾緊該鑽頭60；反之如欲拆卸該鑽頭60則將該連接件20反向螺轉，使該連接件20退離與該推片13的接觸，而當該推片13未受到該推壓時則該彈性夾緊單元12利用該彈性元件121的彈力恢復，使該彈性夾緊單元12產生一復位作用，令該彈性夾緊單元12與該鑽頭60鬆脫同時縮入該夾孔111內，即達到拆卸該鑽頭60之目的。The invention has the characteristics of simple operation and quick disassembly, and is screwed into the second body 14 by the connecting member 20 and is in contact with the push piece 13 if the elastic clip of the collet 10 is to be used. When the tightening unit 12 completely clamps the drill bit 60, the connecting member 20 is continuously spiraled and pushes the push piece 13 to drive the push piece 13 to push the elastic clamping unit 12 synchronously, so that the elastic clamping unit 12 is subjected to the elastic clamping unit 12 The pushing piece 13 is pushed in the accommodating space 110 of the first body 11 and moves toward the clamping hole 111 and passes through the clamping hole 111, and moves the elastic clamping unit 12 toward the clamping hole 111. The more the bit 60 is clamped; if the bit 60 is to be disassembled, the connecting member 20 is reversely screwed, so that the connecting member 20 is retracted from the push piece 13, and when the push piece 13 is not subjected to When the pressing force is applied, the elastic clamping unit 12 recovers by the elastic force of the elastic member 121, so that the elastic clamping unit 12 generates a resetting action, so that the elastic clamping unit 12 and the drill bit 60 are loosened and retracted into the clip. Within the bore 111, the purpose of disassembling the drill bit 60 is achieved.
換言之，本發明僅需利用該連接件20的螺旋動作即可令該夾頭10之彈性夾緊單元12達到夾緊或脫離該鑽頭60，且欲進行鑽頭60與該起子頭40的動換動作時，亦僅需令該連接件60的六角形套接孔21脫離與該起子頭40(為六角形狀)的套接關係，即可改用電動工具50所夾持之起子頭40將螺絲螺鎖於該組裝孔內。In other words, the present invention only needs to utilize the screwing action of the connecting member 20 to cause the elastic clamping unit 12 of the collet 10 to be clamped or disengaged from the drill bit 60, and to perform the dynamic change operation of the drill bit 60 and the screwdriver bit 40. The hexagonal socket hole 21 of the connecting member 60 is only required to be disengaged from the screwdriver head 40 (in the shape of a hexagon), and the screwdriver head 40 held by the power tool 50 can be used to screw the screw. In the assembly hole.
綜上所述，上述各實施例及圖式僅為本發明之較佳實施例而已，當不能以之限定本發明實施之範圍，即大凡依本發明申請專利範圍所作之均等變化與修飾，皆應屬本發明專利涵蓋之範圍內。In the above, the above embodiments and drawings are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention. It should be within the scope of the patent of the present invention.
