利用上述的工具組，請參考第6圖，使用者首先可將旋轉工具的握持段14插置於套筒、氣動工具或電動工具，以配合手工具或動力工具使用，再從工作部11將扭力增強器20套接於旋轉工具10，待扣環30扣抵於環凹槽233即完成組裝，可利用工作部11插抵於螺絲等緊固件90，由套筒另端連接的手工具或由其他動力工具帶動旋轉工具10轉動，用以擰緊或轉鬆緊固件90。Using the above tool set, please refer to FIG. 6, the user can first insert the holding section 14 of the rotating tool into the sleeve, pneumatic tool or electric tool to match with the hand tool or power tool, and then from the working part 11 The torque booster 20 is sleeved on the rotary tool 10, and the assembly is completed when the buckle 30 is buckled in the ring groove 233. The working part 11 can be inserted into the fastener 90 such as a screw, and the hand tool connected by the other end of the sleeve Or, the rotating tool 10 can be driven to rotate by other power tools to tighten or loosen the fastener 90.

在緊固件90轉動的阻力較小時，由於第一端部231與卡合部12之間以及第二端部232與握持段14之間具有錯動間隙，握持段14與工作部11之間的扭力僅經由頸縮段13與卡合部12傳遞，扭力增強器未發揮作用，本實施例之工具組與習用的起子頭等旋轉工具的使用功能一致。When the resistance to rotation of the fastener 90 is small, the holding section 14 and the working section 11 have a misalignment gap between the first end 231 and the engaging section 12 and between the second end 232 and the holding section 14 The torque between them is only transmitted through the necking section 13 and the engaging portion 12, the torque booster does not work, and the tool set of this embodiment has the same function as the conventional rotating tool such as a screwdriver head.

當緊固件90轉動的阻力較大時，例如欲拆卸久未卸下的緊固件時，使用者需要以較大扭力轉動旋轉工具10，旋轉工具首先會於頸縮段13發生扭轉變形，由於第一端部231與卡合部12之間以及第二端部232與握持段14之間具有錯動間隙，卡合部12與握持段14能相對轉動，請參考第7圖，卡合部12與握持段相對轉動後，卡合部12隨即卡抵於第一端部231，且握持段將會卡抵於第二端部，使握持段的扭力能經由第二端部、扭力增強器、第一端部與卡合部傳遞至工作部，而能夠傳遞額外的扭力以轉動緊固件。When the resistance to rotation of the fastener 90 is large, for example, when the fastener that has not been removed for a long time is to be removed, the user needs to rotate the rotary tool 10 with a large torque, and the rotary tool will first be twisted and deformed in the necking section 13 because There is a misalignment gap between the end portion 231 and the engaging portion 12 and between the second end portion 232 and the gripping section 14, the engaging portion 12 and the gripping section 14 can rotate relatively, please refer to FIG. 7, the engaging portion 12 After the relative rotation of the gripping section, the engaging portion 12 then snaps against the first end 231, and the gripping section will snap against the second end, so that the torque of the gripping section can pass through the second end, The torsion booster, the first end and the engaging portion are transmitted to the working portion, and additional torsional force can be transmitted to rotate the fastener.

除上述實施方式之外，如不需要較大的扭力作用時，亦可將扭力增強器卸除，則本創作中的旋轉工具即可如習用的旋轉工具一般使用。In addition to the above embodiments, if a large torque is not required, the torque booster can also be removed, and the rotating tool in this creation can be used as a conventional rotating tool.
