When the grip member 20 is slid to the first position, the grip member 20 is located closest to the working head 11, at which time the dental tool has the shortest length; and when the grip member 20 slides to the In the second position, the grip 20 is located furthest from the working head 11, at which point the dental tool has the longest length.
該固定裝置30設置於該工具本體10與該握持件20之間，用以將該握持件20固定於該第一位置與該第二位置之間的任一位置。該固定裝置30包括一迫緊固定件31以及一迫緊移動件32。該迫緊固定件31具有一呈水滴狀的頭部311以及一螺桿312連接於該頭部311的細端。該螺桿312旋入該柄部12的螺孔14中，並保有一部份位於該螺孔14外。該頭部311的粗端具有一凹槽313，可供一螺絲起子結合，而將該迫緊固定件31旋入該螺孔14。該迫緊移動件32中央具有一穿孔321，且形成有一連接部322與二彈性迫緊部323。該迫緊移動件32套設於該迫緊固定件31的螺桿312上，並位於該工具本體10的柄部12與該迫緊固定件31的頭部311之間。該迫緊固定件31的螺桿312與該迫緊移動件32的連接部322呈螺接之狀態，使轉動該迫緊移動件32時可於一放鬆位置與一迫緊位置間移動。當該迫緊移動件32往該放鬆位置移動時，該迫緊移動件32之彈性迫緊部323是往遠離該頭部311之方向移動；當該迫緊移動件32往該迫緊位置移動時，該迫緊移動件32之彈性迫緊部323是朝向該頭部311之方向移動。當該迫緊移動件32朝向該迫緊位置之方向移動時，該等彈性迫緊部323會沿著該頭部311而逐漸向外擴；當該迫緊移動件32朝向該放鬆位置之方向移動時，該等彈性迫緊部323會因逐漸離開該頭部311而逐漸向內縮。 The fixing device 30 is disposed between the tool body 10 and the holding member 20 for fixing the holding member 20 at any position between the first position and the second position. The fixing device 30 includes a pressing fixing member 31 and a pressing moving member 32. The pressing fixing member 31 has a head portion 311 having a teardrop shape and a screw 312 connected to the thin end of the head portion 311. The screw 312 is screwed into the threaded hole 14 of the shank 12 and has a portion located outside the screw hole 14. The thick end of the head 311 has a recess 313 for a screwdriver to be screwed into the screw hole 14. The pressing and moving member 32 has a through hole 321 in the center thereof, and is formed with a connecting portion 322 and two elastic pressing portions 323. The pressing and moving member 32 is sleeved on the screw 312 of the pressing and fixing member 31 and located between the handle portion 12 of the tool body 10 and the head portion 311 of the pressing and fixing member 31. The screw 312 of the pressing fixing member 31 and the connecting portion 322 of the pressing moving member 32 are screwed together to move between a relaxed position and a pressing position when the pressing moving member 32 is rotated. When the pressing moving member 32 moves to the relaxed position, the elastic pressing portion 323 of the pressing moving member 32 moves away from the head portion 311; when the pressing moving member 32 moves to the pressing position At this time, the elastic pressing portion 323 of the pressing moving member 32 is moved toward the head 311. When the pressing moving member 32 moves toward the pressing position, the elastic pressing portions 323 gradually expand outward along the head portion 311; when the pressing moving member 32 faces the relaxed position When moving, the elastic pressing portions 323 gradually contract inwardly as they gradually move away from the head portion 311.
該迫緊移動件32位於該握持件20中，並略與該握持件20接觸，使轉動該握持件20時可一併帶動該迫緊移動件32移動，使該迫緊移動件32朝向該放鬆位置或朝向該迫緊位置之方向移動。 The pressing and moving member 32 is located in the holding member 20 and slightly contacts the holding member 20, so that when the holding member 20 is rotated, the pressing and moving member 32 can be moved together to make the pressing moving member 32 moves toward the relaxed position or toward the forced position.
當轉動該握持件20使該迫緊移動件32朝向該迫緊位置之方向移動時，該二彈性迫緊部323會沿著該頭部311而逐漸向外擴，而伸入該頭部311與該握持件20之間的間隙，最終達緊迫之狀態，令該握持件20無法轉動也無法滑動。而當朝反方向轉動該握持件20使該迫緊移動件32朝向該放鬆位置之方向移動時，該二彈性迫緊部323會因逐漸離開該頭部311而逐漸向內縮，使該握持件20可自由滑動。 When the grip member 20 is rotated to move the pressing and moving member 32 in the direction of the pressing position, the two elastic pressing portions 323 gradually expand outward along the head portion 311 to extend into the head portion. The gap between the 311 and the grip member 20 is finally brought to an impressed state, so that the grip member 20 cannot rotate or slide. When the gripping member 20 is rotated in the opposite direction to move the pressing and moving member 32 toward the relaxed position, the two elastic pressing portions 323 are gradually retracted by gradually moving away from the head portion 311, so that the The grip 20 is free to slide.
藉此，牙醫師可先轉動該握持件20使該迫緊移動件32朝向該放鬆位置之方向移動，然後滑動該握持件20至預定位置，使該牙科工具具有適當的長度，此時轉動該握持件20使該迫緊移動件32朝向該迫緊位置之方向移動，直至該握持件20無法轉動時，該握持件20即被穩固地固定於該位置，以利牙醫師進行治療。如圖6所示，牙醫師可將該握持件20滑動至具有最長之長度，以利進行後方牙齒之治療。 Thereby, the dentist can first rotate the grip member 20 to move the pressing and moving member 32 toward the relaxed position, and then slide the grip member 20 to a predetermined position to make the dental tool have an appropriate length. Rotating the gripping member 20 moves the pressing and moving member 32 in the direction of the pressing position until the gripping member 20 cannot rotate, the gripping member 20 is firmly fixed at the position for the dentist Treatment. As shown in Figure 6, the dentist can slide the grip 20 to the longest length to facilitate treatment of the posterior teeth.
補充說明，該握持件20的軸孔21中具有一擋止部22，而該工具本體10在該工作頭部11與該柄部12的交接處具有一擋垣15，當該握持件20滑動至該第一位置時，該擋垣15會接觸該擋止部22，使該握持件20無法繼續滑動，而當該握持件20滑動至該第二位置時，該迫緊移動件32會接觸該擋止部22，也使該握持件20無法繼續滑動。 In addition, the shaft hole 21 of the holding member 20 has a stopping portion 22, and the tool body 10 has a dam 15 at the intersection of the working head 11 and the shank portion 12, when the holding member When the slide 20 is slid to the first position, the shackle 15 contacts the stop portion 22, so that the grip member 20 cannot continue to slide, and when the grip member 20 slides to the second position, the urging movement is forced. The member 32 will contact the stop portion 22, and the grip member 20 will not continue to slide.
綜上，本發明所提供之牙科工具延長結構，可讓牙醫師自行調整工具的長度，於伸長時，因結構上力臂加長，而達到省力以及深入患者口腔內部之效能，據以利於治療的進行，再者，於縮短時，可供使用者便於收納及消毒，如是構造簡單、穩固性高，實具商業上的競爭價值。 In summary, the dental tool extension structure provided by the invention allows the dentist to adjust the length of the tool by itself, and when the length is extended, the labor force is lengthened, thereby achieving labor saving and deepening of the inside of the patient's mouth, thereby facilitating treatment. In addition, when shortened, it is convenient for users to store and disinfect. If it is simple in structure and high in stability, it has commercial competitive value.
