彈性件50一端容置於第一容置槽1141,另一端容置於第四容置槽311。本實施方式中,彈性件50為一彈簧。 One end of the elastic member 50 is received in the first receiving groove 1141, and the other end is received in the fourth receiving groove 311. In this embodiment, the elastic member 50 is a spring.
請一併參閱圖6,組裝時,首先將六阻力部20依次嵌入六收容槽1111,磁鐵34嵌入第五容置槽312,將調節件1231收容於第二容置槽1214,並將凸柱1237之自由端依次穿過第二通孔1216及第四通孔1234,使主體1236收容於第三容置槽1215,再將固定銷1233依次穿過第五通孔1235及第六通孔1238進而將調節件1231與鎖定件1232固定;其次,將卡位塊44穿過第三通孔1221使得卡突43抵持於連接部122遠離本體121一端,將起子頭40之主體41自由端穿過第七通孔1321使得圓柱42與固定蓋13相接觸,並將第三螺紋1222與第四螺紋1311旋轉配合使得固定蓋13與調節筒12固定,此時卡突43鄰近第三通孔1221;再將卡位塊44之自由端收容於卡位槽331,並將第一桿31之自由端穿過刻度套筒11之第一通孔110,使得磁鐵34與阻力部20接觸,並將第一螺紋1131與第二螺紋1213旋轉配合使得刻度套筒11與調節筒12相配合;最後將彈 性件50一端連接於第四容置槽311,另一端連接於第一容置槽1141,並將後蓋114與第一圓筒111連接,即完成組裝。 Please refer to FIG. 6 together. When assembling, firstly, the six resistance portions 20 are sequentially inserted into the six receiving grooves 1111, the magnet 34 is inserted into the fifth receiving groove 312, the adjusting member 1231 is received in the second receiving groove 1214, and the convex post The free end of 1237 passes through the second through hole 1216 and the fourth through hole 1234 in order, so that the main body 1236 is received in the third receiving groove 1215, and then the fixing pin 1233 passes through the fifth through hole 1235 and the sixth through hole 1238 in this order. Further, the adjusting member 1231 and the locking member 1232 are fixed; secondly, the locking block 44 is passed through the third through hole 1221 so that the locking protrusion 43 abuts the end of the connecting portion 122 away from the body 121, and the body 41 of the driver head 40 is freely passed through Pass the seventh through hole 1321 to make the cylinder 42 contact the fixed cover 13 and rotate the third thread 1222 and the fourth thread 1311 to fix the fixed cover 13 and the adjusting cylinder 12. At this time, the catch 43 is adjacent to the third through hole 1221. ; Then, the free end of the locking block 44 is received in the locking slot 331, and the free end of the first rod 31 is passed through the first through hole 110 of the scale sleeve 11, so that the magnet 34 contacts the resistance portion 20, and The first thread 1131 and the second thread 1213 are rotationally matched so that the scale sleeve 11 is matched with the adjustment cylinder 12; The bomb One end of the flexible member 50 is connected to the fourth receiving groove 311, and the other end is connected to the first receiving groove 1141. The rear cover 114 is connected to the first cylinder 111, and the assembly is completed.
請一併參閱圖8-9,使用時,首先轉動筒鎖123,使鎖定件1232完全收容於第三容置槽1215,此時鎖定件1232與刻度套筒11沒有發生相互干涉,調節筒12可相對刻度套筒11轉動,轉動調節筒12,使得調節筒12對應到刻度線1121上所需之刻度,再次轉動筒鎖123,使鎖定件1232突出於第三容置槽1215,並與刻度套筒11產生干涉,即鎖定調節筒12與刻度套筒11,完成起子扭力之調節,並可使用起子頭40擰螺絲。當起子頭40轉動所受阻力小於阻力部20與磁鐵34之間所提供之阻力時,起子頭40及轉軸30不會相對套筒10轉動,可擰動螺絲;當起子頭40轉動所受阻力大於阻力部20與磁鐵34之間所提供之阻力時,起子頭40帶動轉軸30轉動,使得起子頭40與轉軸30相對套筒10轉動,使得起子無法擰螺絲。 Please refer to FIGS. 8-9 together. In use, first rotate the cylinder lock 123 so that the locking member 1232 is completely received in the third receiving groove 1215. At this time, the locking member 1232 and the scale sleeve 11 do not interfere with each other, and the cylinder 12 is adjusted. It can rotate relative to the scale sleeve 11 and rotate the adjustment cylinder 12 so that the adjustment cylinder 12 corresponds to the required scale on the scale line 1121. Turn the cylinder lock 123 again so that the locking member 1232 protrudes from the third accommodation groove 1215 and is aligned with the scale. The sleeve 11 interferes, that is, the adjustment cylinder 12 and the scale sleeve 11 are locked to complete the adjustment of the torque of the driver, and the screw 40 can be used to screw the screw. When the resistance of the screwdriver head 40 is less than the resistance provided between the resistance portion 20 and the magnet 34, the screwdriver head 40 and the rotating shaft 30 will not rotate relative to the sleeve 10, and the screw can be screwed; When the resistance provided by the resistance portion 20 and the magnet 34 is greater, the screwdriver head 40 drives the rotating shaft 30 to rotate, so that the screwdriver head 40 and the rotating shaft 30 rotate relative to the sleeve 10, making the screwdriver unable to screw.
不使用時,打開筒鎖123,於彈性件50之作用下,更容易轉動調節筒12使得第一螺紋1131與第二螺紋1213完全重疊,再鎖定筒鎖123即可。 When not in use, open the cylinder lock 123. Under the action of the elastic member 50, it is easier to rotate the adjustment cylinder 12 so that the first thread 1131 and the second thread 1213 completely overlap, and then lock the cylinder lock 123.
可理解,阻力部20還可收容於多邊形筒112之內側壁上,當套筒10之長度最長時,阻力部20與磁鐵34接觸面積最大,第一螺紋1131與第二螺紋1213沒有重疊;當套筒10之長度最短時,阻力部20與磁鐵34接觸面積最小,第一螺紋1131與第二螺紋1213完全重疊。 It can be understood that the resistance portion 20 can also be accommodated on the inner side wall of the polygonal cylinder 112. When the length of the sleeve 10 is the longest, the contact area between the resistance portion 20 and the magnet 34 is the largest, and the first thread 1131 and the second thread 1213 do not overlap; When the length of the sleeve 10 is the shortest, the contact area between the resistance portion 20 and the magnet 34 is the smallest, and the first thread 1131 and the second thread 1213 completely overlap.
本發明之可調扭力起子,利用阻力部與轉軸之間之阻力,即可完成雙向之扭力調節,工程校驗時具有較好之校驗效果,且結構簡單,適合多種起子頭之更換。 The adjustable torque driver of the present invention can complete the two-way torque adjustment by using the resistance between the resistance part and the rotating shaft. It has a good calibration effect during engineering calibration, and has a simple structure, which is suitable for replacing a variety of screwdriver heads.
