Description
本發明係有關於一種組設於起子之握柄內部的扭力調整結構，藉由旋動位於握柄後端之調節旋鈕，即可調節起子之扭力大小，並可做扭力之微調設定。The invention relates to a torsion adjustment structure which is arranged inside the handle of the screwdriver. By rotating the adjustment knob located at the rear end of the handle, the torque of the screwdriver can be adjusted, and the fine adjustment of the torque can be performed.
按，一般用來鎖固及旋鬆拆卸螺絲等物件之起子工具，其握柄與起子桿體大都係固定為一體，在使用時，常因不知螺絲等物件可承受之扭力大小，而隨意旋轉施力，若旋轉施力過度會導致螺絲等物件之螺牙崩牙或螺絲頭之凹槽損壞，而造成無法將螺絲等物件予以拆卸或鎖固之困擾，遂有一種可調整扭力之起子，如專利第M306166號「定扭力起子」，其主要係包括有一握柄、一扭力元件、一導動裝置、一擋止件及一封蓋所組成，該扭力元件包括有一彈性體及一滑塊，其中該彈性體係對應容置於握柄之容組空間，另滑塊周側形成有對應握柄之導槽的導軌，以使滑塊恰可對位導滑於握柄之容組空間，並擋止於彈性體，該導動裝置係包括一導動件及一驅動桿，其中該驅動桿係與導動件相對組設成一體，該驅動桿一端形成有驅動端，驅動端係依序穿伸於滑塊之穿孔、扭力元件及握柄之接孔，且導動件設有對應滑塊之導推面的受推面，且於驅動桿與導動件之相對端面設有定位部，藉此，轉動封蓋可使起子做扭力值之設定；然，習知之定扭力起子雖具有起子扭力值設定之功效，但該起子在設定扭力值上並無法顯示該扭力值之界限，使用者無法得知扭力之設定值，且於每次使用時必須重新設定封蓋轉動之圈數，因此在使用上極不方便，且該定扭力起子僅封蓋一端具有扭力調整之功效，故該起子之扭力設定時無法做微調；緣此，本發明人有鑑於一般在使用起子工具時存在有如上述之缺失，乃潛心研究、改良，遂得以首創出本發明。Press, generally used to lock and loosen the removal of screws and other items of the screwdriver tool, the handle and the driver shaft are mostly fixed as one, in use, often because of the size of the torque that can not withstand the screw and other objects, and rotate freely Applying force, if the rotation force is excessive, the screw of the screw or the like may be broken or the groove of the screw head may be damaged, and the screw or the like may not be disassembled or locked. Therefore, there is a screwdriver capable of adjusting the torque. For example, Patent No. M306166 "Constant Torque Driver" mainly comprises a handle, a torsion element, a guiding device, a stopper and a cover, and the torsion element comprises an elastic body and a slider. The elastic system is correspondingly disposed in the space of the handle of the handle, and the guide rail of the other side of the slider is formed with a guide rail corresponding to the guide groove of the handle, so that the slider can be aligned and guided to the space of the handle. And the driving device comprises a guiding member and a driving rod, wherein the driving rod is integrally formed with the guiding member, the driving rod is formed with a driving end at one end, and the driving end is fastened. Presence through the slider a hole, a torsion element and a contact hole of the handle, and the guiding member is provided with a pushing surface corresponding to the guiding surface of the sliding block, and a positioning portion is provided on the opposite end surface of the driving rod and the guiding member, thereby rotating the sealing The cover can set the torque value of the screwdriver; however, although the conventional torque generator has the function of setting the torque value of the screwdriver, the screwdriver cannot display the limit value of the torque value at the set torque value, and the user cannot know the torque value. The setting value, and the number of turns of the cover rotation must be reset every time, so it is inconvenient to use, and the fixed torque driver only has the effect of torque adjustment at one end of the cover, so the torque setting of the screwdriver cannot be set. Therefore, the inventors of the present invention have invented the present invention in view of the fact that there is a defect as described above when using a screwdriver tool.

本創作之扭力調整結構在組設於起子之握柄A內之前，須先設定其不同扭力值之大小，請參閱第三～五圖所示，可以多邊形工具插設入調節旋鈕8外端面之多邊形凹槽80內，藉由工具來帶動調節旋鈕8旋轉，調節旋鈕8旋轉時會帶動連動件9轉動，連動件9則帶動壓縮件7旋轉，壓縮件7藉由其外螺牙段71與內管1之內螺牙段15相螺設，則會向內管1之內部旋移或向外旋移，當所設定之扭力值較大時，該壓縮件7則向內旋移並抵推止擋件6向內移動，止擋件6則抵推下齒塊5更緊密貼觸於上齒塊4之側壁面上，上齒塊4則受彈簧3之彈性抵持，使下齒塊5之下卡齒51與上齒塊4之上卡齒41更緊密的相互卡掣，其扭力值則為較大；當所設定之扭力值較小時，該壓縮件7則向外移動，其止擋件6與下齒塊5及上齒塊4則受彈簧3彈性抵推亦向外移動，該下齒塊5與上齒塊4之卡掣則較不緊密，其扭力值則為較小；而所設定之扭力值大小，係限制在擋止件6之移動距離，該擋止件6之移動距離則受止付螺絲18限制於內管1之滑槽17內的距離，如此，可控制該扭力所設定的扭力值行程，另可藉由前微調桿2之旋轉來抵推或離開設於內管1內之彈簧3，來調整彈簧3之彈性壓抵力，當前微調桿2進行微調至設定值後，再將內管1上之微調固定孔13予以封口，使前微調桿2得以固定於內管1內不會再移動；當所設定之扭力值越大時，將調節旋鈕8之較大數值對正於握柄A上之指示標記A1，所欲設定之扭力值較小時，則將調節旋鈕8之較小數值對正於握柄A上之指示標記A1，如此，即可將本創作該扭力調整結構組設於起子之握柄A內。The torque adjustment structure of the present invention must be set to the different torque values before being assembled in the grip A of the screwdriver. Please refer to the third to fifth figures, and the polygon tool can be inserted into the outer end surface of the adjustment knob 8. In the polygonal groove 80, the adjustment knob 8 is rotated by the tool. When the adjustment knob 8 rotates, the linkage 9 is rotated, and the linkage 9 drives the compression member 7 to rotate. The compression member 7 is driven by the external screw segment 71. When the inner threaded portion 15 of the inner tube 1 is screwed, it will be rotated or outwardly rotated toward the inner tube 1. When the set torque value is large, the compressing member 7 is rotated inward and offset. The push-stop member 6 is moved inwardly, and the stopper member 6 is pressed against the lower block 5 to be in closer contact with the side wall surface of the upper block 4, and the upper block 4 is elastically resisted by the spring 3 to make the lower tooth The lower teeth of the block 5 under the block 5 and the upper teeth 4 of the upper tooth block 4 are more closely clamped, and the torque value is larger; when the set torque value is small, the compression member 7 moves outward. The retaining member 6 and the lower block 5 and the upper block 4 are elastically urged and moved outward by the spring 3, and the latches of the lower block 5 and the upper block 4 are less tight. The torque value is smaller; and the set torque value is limited to the moving distance of the stopper 6, and the moving distance of the stopper 6 is restricted by the stop screw 18 to the sliding groove 17 of the inner tube 1. The distance between the torque value set by the torque can be controlled, and the elastic pressure of the spring 3 can be adjusted by pushing or rotating the spring 3 provided in the inner tube 1 by the rotation of the front fine adjustment lever 2. After the current fine adjustment lever 2 is finely adjusted to the set value, the fine adjustment fixing hole 13 on the inner tube 1 is sealed, so that the front fine adjustment rod 2 is fixed in the inner tube 1 and no longer moves; when the set torque value is set, When the time is large, the larger value of the adjustment knob 8 is aligned with the indication mark A1 on the handle A. When the torque value to be set is small, the smaller value of the adjustment knob 8 is aligned with the handle A. The indicator mark A1 is thus set, and the torque adjustment structure of the present invention can be set in the handle A of the screwdriver.
使用時，請參閱第三～七圖所示，將該扭力調整結構設於握柄A內（如第四圖所示），該握柄A可供不同之起子桿體A2、A3組設使用（如第四、六圖所示），當欲調整該起子桿體之不同扭力時，僅須以輔助工具B插設入該握柄A後端面上之調節旋鈕8之多邊形凹槽80內（如第七圖所示），藉由輔助工具B轉動該調節旋鈕8，使該調節旋鈕8之扭力值的刻度及數字81對正於握柄A上之指示標記A1位置，即可完成起子桿體A2、A3之扭力調整，且藉由調節旋扭8上之刻度及數字81，可方便調整起子旋動之扭力大小。When using, please refer to the third to seventh figure, the torque adjustment structure is set in the handle A (as shown in the fourth figure), the handle A can be used for different screwdrivers A2, A3 (As shown in the fourth and sixth figures), when the different torques of the driver shaft are to be adjusted, only the auxiliary tool B has to be inserted into the polygonal groove 80 of the adjustment knob 8 on the rear end surface of the handle A ( As shown in the seventh figure, the auxiliary tool B rotates the adjustment knob 8, so that the scale of the torque value of the adjustment knob 8 and the number 81 are aligned with the position of the indicator mark A1 on the handle A, and the screwdriver rod can be completed. The torque adjustment of the bodies A2 and A3, and by adjusting the scale and the number 81 on the knob 8, it is convenient to adjust the torque of the screwdriver.
綜上所述，本發明確實已達到所預期之使用目的與功效，且更較習知者為之理想、實用，惟，上述實施例僅係針對本發明之較佳實施例進行具體說明而已，該實施例並非用以限定本發明之申請專利範圍，舉凡其它未脫離本發明所揭示之技術手段下所完成之均等變化與修飾，均應包含於本發明所涵蓋之申請專利範圍中。In view of the above, the present invention has achieved the intended use and efficacy, and is more desirable and practical than the prior art, but the above embodiments are only specifically described for the preferred embodiment of the present invention.
