Description
本創作係涉及壞損螺栓的取出，尤其是指一種方便取出壞損螺栓，且在取出的過程中避免相對螺栓活動的壞損螺栓取出器。This creation relates to the removal of damaged bolts, especially to a broken bolt extractor that facilitates the removal of damaged bolts and avoids relative bolt movement during removal.
螺栓為常見的一種緊固件，經常用於結合兩個物件；然而，一旦螺栓頭滑牙或者是斷裂時，常會導致螺柱無法自螺孔取出的問題。常見的解決方式有利用衝擊起子敲擊螺栓頭，利用衝擊力鬆開螺柱，亦或者是將螺帽銲固於螺柱，再以扳手將螺帽連同螺柱旋出；近來亦有採用螺柱拔取器來取出壞損螺栓的方式。一種現有的螺柱拔取器，其端部呈錐狀且設有螺紋，其中，現有螺栓拔取器的螺紋與壞損螺栓的螺紋旋向相反；使用現有的螺柱拔取器來移除一壞損的螺栓時，首先必須以一鑽頭在該壞損的螺栓鑽出一孔洞，再將該螺柱拔取器旋入該孔洞，由於該螺柱拔取器的螺紋與該壞損螺栓的螺紋的旋向相反，因此在將該螺栓拔取器旋入該孔洞的過程中，能將該螺栓拔取器螺鎖入該壞損的螺栓，並同時將該壞損螺栓自一螺孔取出。Bolts are a common type of fastener that is often used to join two objects; however, once the bolt head slips or breaks, it often causes the stud to fail to be removed from the screw hole. Common solutions include hitting the bolt head with an impact screwdriver, loosening the stud with impact force, or welding the nut to the stud, and then screwing the nut together with the stud with a wrench; The column extractor is used to remove the damaged bolts. An existing stud extractor having a tapered end and a threaded end, wherein the thread of the existing bolt extractor is opposite to the thread of the broken bolt; the existing stud extractor is used to remove a damage When bolting, first, a hole must be drilled in the damaged bolt with a drill bit, and the stud extractor is screwed into the hole, because the thread of the stud extractor and the thread of the broken bolt are rotated. On the contrary, in the process of screwing the bolt extractor into the hole, the bolt extractor can be screwed into the damaged bolt and the damaged bolt can be taken out from a screw hole at the same time.
只是，現有的螺栓拔取器需要預先以該鑽頭在該壞損的螺栓鑽出所述的孔洞，在操作上較為繁瑣且不方便；由此可知，現有的螺栓拔取器在結構上仍有進步與改善的空間。However, the existing bolt extractor needs to drill the hole in the damaged bolt in advance, which is cumbersome and inconvenient in operation; thus, it is known that the existing bolt extractor still has an improvement in structure. Room for improvement.
