參閱第六至八圖所示，第六圖為拉桿37尚未作動前的立體外觀圖，第七圖則是拉桿37作動後的立體外觀圖，使用時拉動拉桿37朝遠離後支座60的方向移動，拉桿37的鉤部371將驅使旋動件36產生旋動，旋動件36以樞接在各殼座12、13的各螺柱為旋轉中心，令撥動臂361推動離合輪32的擋環322，並使離合輪32朝接近蝸輪構件21的方向移動，蝸輪構件21的各凸鍵211與離合輪32的各鍵槽321將脫離扭矩傳送(如第八圖所示)，此時蝸桿161和導螺桿22將不再繼續傳動，當導螺桿22不旋轉的同時，驅動輪42亦不再驅使從動輪43和可變電阻41的轉軸411轉動，藉由可變電阻41電性連接一控制裝置(圖未示出)，此控制裝置將蝸輪構件21和離合輪32釋放脫離時，轉軸411所旋轉的角度並對應於可變電阻41所得出的特定電阻值載入控制裝置的記憶體中。利用此特定電阻值得出蝸輪構件21的各凸鍵211與離合輪32的各鍵槽321的嵌合位置或釋放脫離位置，而能夠不發生掉失或錯誤的情況。
Referring to the sixth to eighth figures, the sixth figure is a three-dimensional external view before the tie rod 37 is not activated, and the seventh figure is a three-dimensional external view after the tie rod 37 is actuated, and the pull rod 37 is pulled in the direction away from the rear support 60 when in use. Moving, the hook portion 371 of the pull rod 37 will drive the rotating member 36 to rotate, and the rotating member 36 is pivotally connected to each stud of each of the housings 12, 13 as a center of rotation, so that the dialing arm 361 pushes the clutch wheel 32. The retaining ring 322 moves the clutch wheel 32 toward the worm gear member 21, and the respective key 321 of the worm wheel member 21 and the key grooves 321 of the clutch wheel 32 are released from the torque transmission (as shown in FIG. 8). 161 and the lead screw 22 will not continue to drive. When the lead screw 22 does not rotate, the driving wheel 42 will no longer drive the driven wheel 43 and the rotating shaft 411 of the variable resistor 41 to rotate, and the variable resistor 41 is electrically connected. a control device (not shown). When the control device releases the worm wheel member 21 and the clutch wheel 32, the angle of rotation of the rotating shaft 411 and the specific resistance value obtained by the variable resistor 41 are loaded into the memory of the control device. in. With this specific resistance, it is possible to obtain the fitting position or release position of each of the convex keys 211 of the worm wheel member 21 and the key grooves 321 of the clutch wheel 32, and it is possible to prevent loss or error.
