The aforementioned knuckle 64 is received in the accommodating groove 61, the bottom end is pressed against the elastic member 63 and the top end is engaged with the ratchet row 44. The loop sleeve 65 is movably sleeved on the outer periphery of the second handle 50, and is coupled with the lancet 64 by a pin A4.

彎管工序開始時，先將第二手柄50(卡掣座52端) 以連接桿30的第一結合元件A1為支點朝第一手柄10的置管座12方向轉動，並將一管狀元件70穿經第一手柄10的置管座12(置管槽14)，與彎管盤20彎管槽24及作動塊40作動槽42所形成之通道。 At the beginning of the elbow process, the second handle 50 (the end of the cassette 52) is first Rotating the first coupling member A1 of the connecting rod 30 toward the socket 12 of the first handle 10, and passing a tubular member 70 through the socket 12 of the first handle 10 (the tube groove 14), The elbow groove 20 and the actuating block 40 actuate the passage formed by the groove 42.

請參閱第3至5圖所示，次施力於第二手柄50同時以彎管盤20第一結合元件A1(連接孔28)為支點，使第二手柄50異於卡掣座52的一端朝第一手柄10的方向移動；過程中，單向卡掣組之棘舌64與作動塊40之棘齒列44形成卡合，而連動作動塊40以第二結合元件A2(樞設孔41)為軸心，沿彎管盤20之彎管槽24外周緣運動，使伸設於彎管槽24及作動槽42間的管狀元件70產生彎曲的現象。 Referring to FIGS. 3 to 5, the second handle 50 is applied to the second handle 50 while the first coupling member A1 (the connecting hole 28) of the bending plate 20 is used as a fulcrum, so that the second handle 50 is different from the end of the locking seat 52. Moving in the direction of the first handle 10; during the process, the knuckle 64 of the unidirectional cassette group is engaged with the ratchet row 44 of the actuating block 40, and the actuating block 40 is coupled to the second coupling element A2 (the pivoting hole 41) The axis is moved along the outer periphery of the curved groove 24 of the curved disk 20 to cause the tubular member 70 extending between the curved groove 24 and the actuating groove 42 to be bent.

該使用者力量不足時，再藉由棘舌64與作動塊40之棘齒列44可單向退讓互動，移動第二手柄50反向第一手柄10方向運動位移，尋求較佳施力之力矩；過程中，棘舌64受棘齒列44推頂而壓縮彈性元件63，使棘舌64退縮沒入容置槽61中，而對作動塊40之棘齒列44形成退讓，使第二手柄50以作動塊40之第三結合元件A3(內樞孔43、兩外樞孔54)為軸心擺動，俾使棘舌64相對棘齒列44運動，待棘舌64位移到棘齒列44預設位置後，再度將第二手柄50(相異卡掣座52另一端)向第一手柄10方向運動扳動，達成省力之效益。 When the user's power is insufficient, the thorns 64 and the ratchet row 44 of the actuating block 40 can be retracted and unidirectionally moved, and the second handle 50 is moved in the opposite direction of the first handle 10 to seek a better torque. During the process, the lance 64 is pushed up by the ratchet row 44 to compress the elastic member 63, so that the lance 64 is retracted into the accommodating groove 61, and the ratchet row 44 of the actuating block 40 is retracted to make the second handle The third coupling member A3 (the inner pivot hole 43, the two outer pivot holes 54) of the actuating block 40 is pivoted about the axis, so that the spine 64 moves relative to the ratchet row 44, and the ratchet 64 is displaced to the ratchet row 44. After the preset position, the second handle 50 (the other end of the dissimilar card holder 52) is again moved in the direction of the first handle 10, thereby achieving the labor saving effect.

請參閱第6、7圖所示，透過環套65連動插銷A4及棘舌64，俾使棘舌64壓縮彈性元件63，使棘舌64沒入容置槽61中，方便卡掣座52(棘舌64)快可速於棘齒列44外周緣運動。 Referring to the figures 6 and 7, the bolt A4 and the knuckle 64 are interlocked through the ring sleeve 65, so that the knuckle 64 compresses the elastic member 63, so that the knuckle 64 is immersed in the accommodating groove 61, facilitating the shank 52 ( The spine 64) is faster than the outer periphery of the ratchet row 44.

以上所述說明，僅為本發明的較佳實施方式而已，意在明確本發明的特徵，並非用以限定本發明實施例的範 圍，本技術領域內的一般技術人員根據本發明所作的均等變化，以及本領域內技術人員熟知的改變，仍應屬本發明涵蓋的範圍。 The above description is only the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the embodiments of the present invention. </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt;
