以上所述即為本發明實施例各主要構件之結構及其組態說明。至於本發明的作動方式及功效作以下說明。The above description is the structure and configuration description of each main component of the embodiment of the present invention. The mode of operation and efficacy of the present invention are described below.
參閱第9至11圖所示,當該擺動盤38的止動部36對準該掣動件42的卡制部423時,作動該扳動件43向該擺動件31方向移動,並以頂制端431頂向該卡制部423,使卡制部423可確實的卡制於該止動部36,該擺動件31即可保持不動,而驅動選擇裝置40呈不驅動狀態。須說明的是,該驅動選擇裝置40呈不驅動狀態是指當該掣動件42的卡制部423被該扳動件43朝該擺動件31方向帶動後,該掣動件42的掣動柱422會同時帶動該移動件41朝該擺 動件31的反方向移動,使該穿軸3脫離於該擺動盤38的置孔35,最終使該主動軸22不再帶動該擺動件31、勾臂24、及上環勾23作動。Referring to the figures 9 to 11, when the stopping portion 36 of the swash plate 38 is aligned with the locking portion 423 of the swaying member 42, the urging member 43 is moved in the direction of the oscillating member 31, and is topped. The manufacturing end 431 is directed toward the locking portion 423, so that the locking portion 423 can be surely locked to the stopping portion 36, and the swinging member 31 can be kept stationary, and the driving selection device 40 is in a non-driving state. It should be noted that the driving selection device 40 in the non-driving state means that when the locking portion 423 of the cocking member 42 is driven by the urging member 43 toward the oscillating member 31, the cocking member 42 is tilted. The column 422 will simultaneously drive the moving member 41 toward the pendulum The moving member 31 moves in the opposite direction to disengage the threading shaft 3 from the hole 35 of the swash plate 38, and finally the driving shaft 22 no longer drives the swinging member 31, the hook arm 24, and the upper ring hook 23 to operate.
參閱第7、8圖所示,當作動該扳動件43,並使該頂制部431往離開該卡制部423方向移動時,該掣動件42之掣動端421受該彈性件44的拉引,使該移動件41靠向驅動件33,該移動件41上的穿軸34具有向擺動件31穿置之預力,該主動軸22轉動帶動該驅動件33時,待該穿套部332對準該擺動盤38的置孔35,該穿軸34即可穿入該置孔35內帶動該擺動件31及該勾臂24,該驅動選擇裝置40呈驅動狀態。Referring to FIGS. 7 and 8, when the trigger member 43 is moved and the top portion 431 is moved away from the locking portion 423, the swing end 421 of the tilting member 42 is received by the elastic member 44. Pulling the moving member 41 against the driving member 33, the threading shaft 34 on the moving member 41 has a pre-stress to the swinging member 31. When the driving shaft 22 rotates to drive the driving member 33, the wearing portion 33 is to be worn. The sleeve portion 332 is aligned with the through hole 35 of the swash plate 38. The through shaft 34 can penetrate the through hole 35 to drive the swinging member 31 and the hook arm 24. The driving selection device 40 is in a driving state.
值得一提的是,複參閱第7、8圖所示,當該擺動盤38上的止動部36未對準該掣動件42的卡制部423時,該掣動件42的卡制部423會受限於該擺動盤38的弧形側面383,使得該扳動件43無法帶動該卡制部423朝該擺動盤38方向扳動一距離,而讓該穿軸34保持穿入在該擺動盤38的置孔35內的狀態(即該驅動選擇裝置40呈驅動狀態),此時,該上環勾23則如第1圖所示,係位於該針板13的上方;複參閱第10、11圖所示,當該擺動盤38上的止動部36對準該掣動件42的卡制部423時,該掣動件42的卡制部423不再受限於該擺動盤38的弧形側面383,使得該扳動件43得以帶動該卡制部423朝該擺動盤38方向扳動一距離,而讓該穿軸34脫離該擺動盤38的置孔35之外的狀態(即該驅動選擇裝置40呈不驅動狀態),此時,該上環勾23則如第2圖所示,係位於該針板13的下方,據此,本發明在控制該勾臂24呈不驅動狀態時,可以確保所帶動的上環勾23位於該針板13的下方,避免該縫針14作動時與該上環勾23產生干涉,因此操控上較為確定,而達到該上環勾23於不驅動狀態可確實定位的目的。It should be noted that, as shown in FIGS. 7 and 8, when the stopper portion 36 on the swash plate 38 is not aligned with the locking portion 423 of the swaying member 42, the swaying member 42 is clamped. The portion 423 is limited to the curved side surface 383 of the swash plate 38, such that the trigger member 43 cannot drive the locking portion 423 to a distance in the direction of the swash plate 38, and the through shaft 34 is kept penetrated. a state in the hole 35 of the swash plate 38 (that is, the drive selection device 40 is in a driving state). At this time, the upper ring hook 23 is located above the needle plate 13 as shown in FIG. 1; As shown in FIGS. 10 and 11, when the stopper portion 36 of the swash plate 38 is aligned with the locking portion 423 of the swaying member 42, the locking portion 423 of the swaying member 42 is no longer limited to the swash plate. The curved side surface 383 of the 38 causes the triggering member 43 to drive the locking portion 423 to a distance in the direction of the swash plate 38, and the insertion shaft 34 is disengaged from the hole 35 of the swash plate 38. (ie, the drive selection device 40 is in a non-driving state). At this time, the upper ring hook 23 is located below the needle plate 13 as shown in FIG. 2, and accordingly, the present invention controls the hook arm 24 to be Drive When it is ensured that the upper ring hook 23 is located below the needle plate 13, to avoid interference with the upper ring hook 23 when the needle 14 is actuated, the control is relatively determined, and the upper ring hook 23 can be surely driven. The purpose of positioning.
值得說明的是,複參閱第9、12圖所示,由於該擺動件31另端313以一螺栓37固設有一擺動盤38,該擺動盤38上設有該止動部36及該置孔 35,且該擺動盤38供該螺栓37穿過處形成一長形之調整孔382,使該擺動盤38所在的角度可被調整與定位,因此,可控制當該擺動盤38上的止動部36對準該掣動件42的卡制部423時,該上環勾23與該針板及縫針之間的相對位置,僅需控制該上環勾23不與作動時的縫針產生干涉即可。It is to be noted that, as shown in FIG. 9 and FIG. 12, since the other end 313 of the oscillating member 31 is fixed with a swaying disc 38 by a bolt 37, the swash plate 38 is provided with the stopping portion 36 and the through hole. 35, and the swash plate 38 is provided with an elongated adjusting hole 382 through the bolt 37, so that the angle at which the swash plate 38 is located can be adjusted and positioned, so that the stop on the swash plate 38 can be controlled. When the portion 36 is aligned with the locking portion 423 of the swaying member 42, the relative position between the upper ring hook 23 and the needle plate and the needle is only required to control the upper ring hook 23 from interfering with the needle at the time of actuation.
綜上所述,上述各實施例及圖示僅為本發明的較佳實施例而已,當不能以之限定本發明實施之範圍,即大凡依本發明申請專利範圍所作的均等變化與修飾,皆應屬本發明專利涵蓋的範圍內。In the above, the above embodiments and the illustrations are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equal variations and modifications made by the scope of the patent application of the present invention are It should be within the scope of the patent of the present invention.
