在前述推棒126的轴部126e的外周上,卷绕着复位弹簧132,复位弹簧132的前端接触于在前述旋转接套130的内部所形成的阶梯部130d(图5(b))。 On the outer periphery of the shaft portion 126e of the pushing rod 126, the return spring 132 is wound around the front end of the return spring 132 in contact with the contact stepped portion 13Od (FIG. 5 (b)) formed inside the sleeve 130 in the rotary. 此外,复位弹簧132的后端接触于推棒126的阶梯部126g,推棒126由复位弹簧132始终朝后退方向加力。 Further, the rear end of the return spring 132 contacts the stepped portion 126g of the push rod 126, the push rod 126 is always urged by a return spring 132 toward the backward direction. 此外,如果前述推棒126的收容部126f和轴部126e的前端使推棒126克服复位弹簧132的加载力而前进,则插过前述旋转接套130而从手柄部12突出成为可能。 Further, if the accommodating portion 126f and the shaft portion of the push rod 126 so that the distal end 126e of the pushing rod 126 against the biasing force of the return spring 132 is advanced, it is inserted through the rotation of the sleeve 130 is made possible from the protruding portion 12 of the handle.

构成以上的手柄部12的零件仅有复位弹簧132是金属制的,其余零件,手柄右壳121、手柄左壳122、扳机123、推棒126、棘爪构件128、旋转接套130全都是塑料制的。 Reset only parts constituting the handle portion 12 above the spring 132 is made of metal, the remaining parts, the right handle shell 121, left handle shell 122, the trigger 123, the push rod 126, the pawl members 128, 130 are all rotatably attached plastic sleeve system. 最好是,如果这些塑料零件全都用相同的塑料来形成,则在如后所述的进行再利用处理的场合,更为有利。 Preferably, if all of the plastic parts formed by the same plastic, then as the case of the reuse processing, is more advantageous.

首先仅说明像以上这样所构成的手柄部12的作用。 First of illustration only handle portion 12 thus constituted as above. 如果操作者握持前述握持部124a,扣动扳机123使之接近握持部124a,则因为扳机123的上端配合于推棒126的突起126a,所以推棒126前进,也就是向杆部14一方移动。 If the operator holds the grip portion 124a, so as to pull the trigger 123 closer to the grip portion 124a, the upper end of the trigger 123 as the push rod fitting projection 126 is 126a, the pushing rod 126 forward, i.e. toward the rod section 14 party movement. 借此,棘爪构件128的前端头部接触于推棒126的棘齿126b,如图6中所示,其前端头部被向前侧,也就是杆部14一侧压倒。 Accordingly, the distal head portion of the pawl member 128 in contact with the pushing rod 126b 126 of the ratchet tooth, as shown in Figure 6, the front end of the head which is the front side, i.e. the side of the rod portion 14 overwhelming. 而且,棘齿128b与推棒126的的棘齿126b啮合。 Further, the ratchet 128b of the push rod 126 engages the ratchet teeth 126b. 同时,板弹簧部128d接触门124d的位于图6中右端的柱,图6中,向右凸地弯曲。 Meanwhile, the plate spring portion 128d contacts the door 124d is located in the right end column in FIG. 6, FIG. 6, right convexly curved. 靠此一板弹簧部128d的弹簧力,棘爪构件128的前端头部向推棒126的棘齿126b一方压住,特别是向图6的右上方压住。 By a spring force of this spring plate portion 128d of the front end of the pawl member 128 presses the head portion to one of the ratchet teeth 126b of the pushing rod 126, in particular pressed to the upper right of FIG. 6. 如果继续推棒126的前进,则棘爪构件128的前端头部摇动过图6的右上方和左下方之间,其棘齿128b一边从棘齿126b适当退避一边对棘齿126b相对移动。 If the bar 126 continues to push forward, the front end of the pawl member between the head portion 128 of the swing through the upper right and lower left in FIG. 6, the ratchet 128b side from the side ratchet teeth 126b of the ratchet teeth properly retracted 126b relative movement. 如果停止扳机123的摇动运动,推棒126的前进运动停止,则棘爪构件128的前端头部向右上方向棘齿126b一方推压,确保棘齿128b与棘齿126b之间的啮合,推棒126的停止被保持。 If the shaking motion of the trigger stop 123, forward movement of the push rod 126 is stopped, the front end of the pawl member 128 in the rightward direction and a head portion ratchet teeth 126b pressed one, to ensure the engagement between the ratchet teeth of the ratchet teeth 128b and 126b, push rods 126 cease to be maintained. 此时,虽然在推棒126上靠复位弹簧132的加载力作用着使推棒126后退的力,但是因为棘齿128b与棘齿126b啮合,棘齿128b无法向允许推棒126后退的方向退避,故推棒126的后退被禁止。 In this case, although the effect of making the push rod 126 backward force against the biasing force of the return spring 132 in the pushing rod 126, but because the engaging ratchet teeth 128b of the ratchet teeth 126b, 128b ratchet directions Unable to allow pushing rod 126 is retracted back , so that the pushing rod 126 is retracted prohibited.

如果进一步扣动扳机123,推棒126进一步前进,则如图7中所示,棘爪构件128的棘齿128b与推棒126的棘齿126b的啮合脱开,棘爪构件128的前端头部进入退避部126d处。 If further pull the trigger 123, push rod 126 is advanced further, the engaging 7, the ratchet pawl member 128b of the pushing rod 128 and ratchet teeth 126 of FIG 126b is disengaged from the front end of head portion 128 of the pawl member enter at the retreat portion 126d. 这样一来,推棒126就从棘爪构件128解脱了。 Thus, the push rod 126 to the pawl member 128 freed.

如果解除对扳机123的力,则推棒126靠复位弹簧132的加载力后退。 If the force on the trigger 123 is released, the push rods 126 against the biasing force of the return spring 132 is retracted. 此时,棘爪构件128的前端头部接触于推棒126的棘齿126b,如图8中所示,其前端头部被向后侧,也就是与杆部14相反一侧压倒。 At this time, the front end of the pawl member 128 in contact with the head of the ratchet teeth 126 of the pushing rod 126b, shown in Figure 8, the front end of the head which is to the rear side, i.e. opposite to the rod portion 14 overwhelming. 而且,棘齿128c与推棒126的棘齿126b啮合。 Further, the ratchet teeth 128c with the ratchet 126 engages the pushing rod 126b. 同时板弹簧部128d接触门124d的位于图8中左端的柱,图8中,向左凸地弯曲。 While the plate spring portion 128d contacts the door 124d is located in the left end column in FIG. 8, FIG. 8, leftward convexly curved. 靠此一板弹簧部128d的弹簧力,棘爪构件128的前端头部向推棒126的棘齿126b一方压住,特别是向图8的左上方压住。 By a spring force of this spring plate portion 128d of the front end of the pawl member 128 presses the head portion to one of the ratchet teeth 126b of the pushing rod 126, in particular pressed to the left in FIG. 8. 如果继续推棒126的后退,则棘爪构件128的前端头部摇动过图8的左上方和右下方之间,其棘齿128c一边从棘齿126b适当退避一边对棘齿126b相对移动。 If you continue to push back the rod 126, the head portion 128 of the front end of the pawl member between the upper left and lower right swing through FIG. 8, which ratchet teeth 128c from the side ratchet teeth 126b of the ratchet teeth properly retracted side 126b relative movement. 假如在图8那样的中途状态下再次扣动扳机123,使推棒126前进,则棘齿128c与棘齿126b啮合,因为棘齿128c无法向允许推棒126前进的方向退避,故推棒126的前进被禁止。 If the trigger is pulled again in the intermediate state of FIG. 8 as 123, so that the push rod 126 advances, the ratchet engagement with the ratchet teeth 128c 126b, 128c as not to allow the ratchet advancing direction of the pushing rod 126 is retracted, the push rod 126 so the advance is prohibited.

而且,如果推棒126进一步后退,则返回到图2的状态,棘爪构件128的棘齿128c与推棒126的棘齿126b的啮合脱开,棘爪构件128的前端头部进入退避部126c处。 Further, if the rod 126 is further pushed back, the process returns to the state of FIG. 2, the ratchet member engaging pawl 128c and the push rod 128 the ratchet 126 is disengaged from the teeth 126b, distal head portion 128 of the pawl member into the retracted portion 126c place. 这样一来,推棒126就从棘爪构件128解脱了。 Thus, the push rod 126 to the pawl member 128 freed.

通过以上推棒126和棘爪构件128的作用,可靠地进行由扳机123的完全扣动动作和完全解除动作组成的一个循环的动作,阻止半途而废的动作,如后所述夹子C的赋予和下一个夹子C的准备得以可靠地进行。 Reliably operated by a cycle operation the trigger 123 is fully pulled, and movements and completely released by the action of the above pushing rod 126 and the pawl member 128, preventing the halfway operation, as described later, and imparting the clip C preparation of a clip C is reliably performed.

在此一手柄部12中,因为棘爪构件128本身备有板弹簧部128d,故可以省略另外的弹簧构件,可以减少零件数。 In this handle portion 12, since the pawl member 128 itself is provided with a plate spring portion 128d, it is possible to omit an additional spring member, the number of parts can be reduced.

此外,在本发明中,因为谋求零件的减少也使构成简化,故其装配性,特别是在把导向机构16、钳口18、推杆20、钳口闭锁构件22和夹子供给机构24的各零件收容于非常细的杆部14内方面有优越性。 In the present invention, since the parts also seek to reduce the configuration is simplified, the assembling of which, particularly in the guide mechanism 16, the jaws 18, the push rod 20, the latch jaw member 22 and the clip feeding mechanism 24 each part accommodated in a very thin stem portion 14 aspect of superiority. 下面就其装配步骤进行说明。 Its assembly will now be described step.

〔9〕装配步骤首先,在把零件插入杆部14内的导管144内之前,预先把多个夹子C、夹子推出棒166、夹子弹簧168放在钳口18所焊接的夹子盒162内部,按已经说明的那样的图12的步骤把夹子盒162和夹子盒盖164结合起来,装配导向机构16。 [9] The first assembly step, before the catheter 144 is inserted into the inner part of the rod portion 14, a plurality of clips C in advance, introduction of rod clamps 166, 168 on the spring clip 162 inside the welding jaws 18 of the clip case, press FIG step as already described in the clip 12 and the clip cartridge cover 162 combined 164, guide assembly 16. 进而,把夹子架242的切起部242b经由复位棒248的开口248a插入弹簧轴245后端的窄缝中,把复位弹簧244配置于弹簧轴245的外周,把弹簧轴245的前端插入复位棒248的筒部248b内,把这些夹子架242、复位弹簧244、弹簧轴245、复位棒248整体地装配起来。 Further, the cut and raised portion of the clip holder 242b 242 via a reset rod spring 248 is inserted into the shaft 248a of the slit opening 245 in the rear end, the return spring 244 disposed on the outer periphery of the spring shaft 245, the shaft 245 is inserted into the distal end of the spring reset rod 248 the inner cylindrical portion 248b, these frame clips 242, return spring 244, the spring shaft 245, the reset rod 248 integrally assembled. 而且,进一步把复位棒248的筒部248b插入前述导向机构16的后端。 Moreover, the further cylindrical portion 248 of the reset rod 248b is inserted into the rear end 16 of the guide means.

此外,把卡止构件246的轴部246a插入后推杆202的长孔202b的轴承窝202d中。 Further, the shaft portion 246 of the engaging member 246a is inserted into the long hole 202d pusher bearing pocket 202 in 202b.

接着,把后推杆202从其后端插入导管144中。 Next, after the pusher bar 202 is inserted into conduit 144 from its rear end. 在把后推杆202插入导管144内一定程度时,使与夹子架242、前述导向机构16等整体地装配的夹子架242的后端从上边盖住后推杆202的前端。 When the push rod 202 is inserted into the catheter 144 after the certain degree, the distal end of the clip bracket 242, the rear end of the guide means 16 and the like integrally mounted bracket clip 242 after the push rod 202 from the top cover. 此时,注意使卡止构件246的伸出部246b卡止于夹子架242的卡止孔242c中。 In this case, note that the locking member 246 protruding portions 246b latch onto the clip holder 242 of the locking hole 242c. 而且,把后推杆202与夹子架242一起插入导管144内,在后推杆202即将完全插入导管144内时,把后推杆202与前推杆204结合起来,前推杆204也一起插入。 Moreover, after the push rod 202 of the clip 242 are inserted together into the catheter holder 144, when the push rod 202 will be completely inserted into the catheter 144, the plunger 202 after the pre-fader 204 combined with the front plunger 204 inserted together . 此外,预先装配成一体的弹簧轴245、复位弹簧244、复位棒248、导向机构16和钳口18也与夹子架242一起插入导管144内。 In addition, pre-assembled into a shaft integral spring 245, return spring 244, a reset rod 248, a guide mechanism 16 and the jaws 18 are also inserted into the clip holder 242 along conduit 144. 而且在前推杆204即将完全插入导管144内时,把前述钳口闭锁构件22连接于前推杆204上,插入导管144内。 When the plunger 204 and the front will be completely inserted into the catheter 144, to the latch jaw member 22 is connected to the front of the plunger 204, the conduit 144 is inserted. 而且,把钳口18的突起18d、18d推入导管144的开口144b并固定。 Further, the jaws 18 of the projection 18d, 18d is pushed into the opening 144b of the conduit 144 and is fixed. 最初插入的后推杆202的被收容部202a从导管144的后端突出。 After the initial insertion of the push rod 202 is housed portion 202a projecting from the rear end 144 of the catheter.

像以上这样,对导管144内的插入简单地结束。 As set forth above, is simply inserted into the end of the conduit 144. 接着,扣动预先装配的手柄部12的扳机123,使推棒126前进,使其收容部126f从手柄部12的前端开口突出。 Next, pull the trigger of the handle portion 12 of the pre-assembled 123, so that the push rod 126 advances, so that the housing from the front end portion 126f of the handle portion 12 of the projecting opening. 而且,当把从前述导管144的后端突出的后推杆202的被收容部202a连接于推棒126的收容部126f,解除扳机123时,则后推杆202的后端与推棒126一起被拉入手柄部12。 Further, when the rear end of the plunger after the conduit 144 protrudes from the accommodating portion 126f is housed portion 202a is connected to a push rod 126 202, the trigger 123 is released, the rear end of the push rod 126 and push rod 202 with pulled into the handle portion 12. 最后把旋钮142从导管144的前端通过,拧在前述手柄部12的旋转接套130上,用旋转接套130和旋钮142夹住导管144后端的法兰部144a,借此手柄部12与杆部14完全连接起来。 Finally, the knob 142 from the distal end of the catheter 144 through, screwed onto the handle portion 12 of the rotation of the sleeve 130, the sleeve 130 by rotating knob 142 and the flange portion 144 sandwiched between the rear end of the conduit 144a, whereby the grip portion 12 with the rod section 14 is completely connected. 通过以上的作业,装配结束。 By the above operation, the end of the assembly.

像这样,与现有技术品相比,零件数减少了,进而,因为削减了小的弹簧零件等,简化了构成,故装配变得非常简单。 Thus, compared to the prior art products, the number of parts can be reduced, and further, since the cut parts of the small spring like configuration is simplified, it becomes very simple assembly.

〔10〕夹子供给机构的变形例图28是表示夹子供给机构34的另一种构成的图。 [10] The modification of FIG clip feed mechanism 28 is a clip feed mechanism of another configuration 34 of FIG. 本变形例中的夹子供给机构34沿由杆部14的轴向延伸的夹子架342、给夹子架342向轴向后方加力的复位弹簧244(加力机构)、复位弹簧244卷绕于其周面上的弹簧轴245、插入后推杆202且能够沿横向也就是左右方向摇动的卡止构件346、以及卡合于前述在夹子盒162的后端所形成的卡合孔162d中的复位棒348来构成。 The clip feeding mechanism of the present modified embodiment of the clip 34 along the carrier by an axially extending portion 14 of the stem 342, the clip body 342 to the rearward axial biasing of the return spring 244 (urging means), the return spring 244 wound around the its spring axis peripheral surface 245, the push rod 202 and can be inserted in the lateral direction is about swinging locking member 346, and engaged with the engaging holes 162d at the rear end of the clip cartridge 162 formed in reset rod 348 is constituted. 再者,与前述构成同一的构件,被赋予同一标号。 Further, with the identical constituting member is denoted by the same reference numerals.

夹子架342与夹子架242的不同之处在于,没有卡止孔242c,而是形成侧部缺欠的缺口孔342c。 The clip of the clip bracket 342 that is different from the frame 242, there is no locking holes 242c, 342c hole but a cutout portion side imperfections. 缺口孔342c由位于后部而缺欠大于夹子架342的左右方向中心线的第1缺口孔342c1,和位于第1缺口孔342c1前方,缺欠小于左右方向中心线的第2缺口孔342c2组成。 Cutout hole 342c of the cutout in the rear right and left direction of the clip body 342 is greater than the first notch centerline hole 342c1, and a second notch located at the first hole 342c1 front hole cutout, the cutout is smaller than the left-right direction center line 342c2 composition. 其他方面与夹子架242几乎相同。 Other aspects of the clip bracket 242 is almost the same.

卡止构件346是由金属制成的板簧,嵌入后推杆202的长孔202b中,一端安装于后推杆202的长孔202b中。 The locking member 346 is a plate spring made of metal, the push rod fitted in the long hole 202b 202, attached to the rear end of the push rod in the elongated hole 202b 202. 此外,在顶上部形成从长孔202b突出的卡止部346b,该卡止部346b能够在长孔202b的范围内以前述安装点为中心沿左右方向摇动。 Further, the top portion 202b is formed projecting from the long hole 346b of the engaging portion, the engaging portion 346b can be in the range of the long hole 202b of the attachment point to the center of swinging left and right direction. 卡止构件346靠其板簧的弹性始终在长孔202b内加力以便沿轴向成为平行,前述卡止部346b卡止于前述夹子架342的缺口孔342c的第1缺口孔342c1。 The locking member 346 is always urged in the elongated hole 202b of the leaf spring against its elasticity so as to be parallel to the axial direction, the engaging portion 346b is engaged with the cutout holes 342 of the bracket clip 342c of the first notches hole 342c1.

此外,在复位棒348的后端形成越往前左右方向越宽的凸轮面348d。 Further, a wider lateral direction of the forward cam surface 348d at the rear end of the reset rod 348. 此一凸轮面348d与前述卡止构件346相关,使卡止构件346的卡止部346b向横向也就是左右方向移动,发挥使夹子架342后退的作用。 This cam surface 348d and the associated latch member 346, so that the card locking member 346 of locking portion 346b is moved laterally to the left and right direction, so that play a role in the clip holder 342 is retracted.

在像以上这样所构成的夹子供给机构34中也与夹子供给机构24同样地作用。 24 also act similarly with the clip feeding mechanism 34 as the clip feeding mechanism constituted in the above this. 也就是说,如果后推杆202前进,则卡止构件346一起前进,因为卡止构件346的卡止部346b卡止于夹子架342的第1缺口孔342c1中,所以夹子架342也一起前进。 That is, if the push rod 202 advances, the engagement member 346 are advanced together, because the card locking member 346 is engaged with the stopper portion 346b of the first hole 342c1 notch in the clip body 342, the body 342 also advances with the clip . 夹子架342前进,其前端推出前头的夹子C而向钳口18的钳口要素18a、18a之间导向如图25中所示。 The clip bracket 342 forward, the front end of the clip C and introduced to the top of the jaw 18 of the jaw elements 18a, 18a between the guide 25 shown in FIG. 接着,卡止构件346的卡止部346b与位于复位棒348后端的凸轮面348d干涉。 Next, the card locking member 346 of locking portion 346b and the cam surface 348d of the rear end of the reset rod 348 to interfere. 如图29中所示,靠此一凸轮面348d使卡止构件346向左右方向摇动,卡止构件346的卡止部346b从夹子架342的第1缺口孔342c1退出。 In Figure 29, against a cam surface 348d so that this locking member 346 swing in the lateral direction, the locking member locking portion 346b of the card 346 exits from the first hole 342c1 cutout 342 of the clip bracket. 借此,夹子架342从卡止构件346解脱,故靠复位弹簧244的加载力后退。 Accordingly, the clip body 342 is freed from the locking member 346, so that the biasing force of the return spring 244 on the back.

此外,如果夹子C的赋予作业结束,后推杆202后退,则卡止构件346也后退,其卡止部346b通过夹子架342的第2缺口孔342c2,再次卡止于先前已经后退的夹子架342的第1缺口孔342c1中。 Furthermore, if the clip C imparting job end, the push rod 202 retracted, the locking member 346 is also retracted, its engaging portion 346b 342c2, back again has been previously engaged by the second clip frame cutout holes 342 of the clip bracket the first notch in the hole 342 342c1.

这样一来,与夹子供给机构24同样,也可以使用由板弹簧组成的卡止构件346来构成夹子供给机构34。 Thus, the same clip feeding mechanism 24, the locking member may be used consisting of a plate spring 346 constitute a clip feeding mechanism 34.

〔11〕手柄部的分解结构如果用光了夹子,则有必要进行处置。 [11] If an exploded structure of a handle portion of the clip runs out, it is necessary for disposal. 下面就此一手柄部12的处置步骤进行说明。 The following step of this disposal a handle portion 12 will be described. 首先,旋松杆部14的旋钮142与手柄部12的旋转接套130的螺纹连接,把杆部14从手柄部12分离。 First, the knob portion 14 unscrewing of the rotary shaft 142 and the handle portion 12 of the threaded nipple 130, the handle portion 14 is separated from the portion 12.

接着,如果向壳体内方向推动分别在前述手柄右壳121和手柄左壳122的壳体面上通过冲压而形成的弹性片121a、122a,使弹性片121a、122a卡合于肋130b上,则基部130a不能相对手柄壳体124旋转。 Subsequently, if the push surface of the elastic pieces, respectively the handle housing 121 and the right case 122 of the left case the handle is formed by stamping 121a, 122a into the direction of the housing, the elastic piece 121a, 122a engages ribs 130b, the base 130a relative to the handle housing 124 can not rotate. 如果在此一状态下用扳手等相对于基部130a拧动螺纹部130c,则旋转接套130在脆弱部130e处破断(参照图5(c)),位于壳体内部空间内的复位弹簧132可以取出(图30)。 If, in this state using a wrench and the like with respect to the base 130a screwing the screw portion 130c, the rotation of the sleeve 130 broken (see FIG. 5 (c)) in the fragile portion 130e situated along the return spring within the interior space of the housing 132 can be removed (FIG. 30). 这样一来,因为可以取出作为唯一的金属零件的复位弹簧132,其余是塑料零件,故可以分别处置金属零件和塑料零件。 Thus, as can be taken as the only metal parts of the return spring 132, the remaining plastic parts, it is possible to dispose the metal parts and plastic parts, respectively.

此外,也可以随意地用图31中所示的附件134来止住旋转接套130的旋转。 Further, the attachment 134 can optionally be used as shown in FIG. 31 to stop the rotation of the sleeve 130 in rotation. 附件134形成环形的主体134a和从主体134a对应于前述附件插入孔130f而形成的突起134b。 Accessory 134 forming an annular body 134a and the projections 134b of the main body 134a corresponding to the accessory insertion hole 130f formed. 前述旋转接套130的螺纹部130c可以通过环形主体134a的内侧。 The rotation of the sleeve 130 can be threaded portion 130c by the inner annular body 134a. 此外,在手柄壳体124的前端开口处,在手柄右壳121与手柄左壳122之间形成间隙,此一间隙成为窄缝124e、124e,窄缝124e、124e在与附件插入孔130f调整时,成为与附件插入孔130f连通的间隔和数目。 Further, the front end opening 124 of the handle housing, a gap is formed between the handle and the right handle shell 121 left case 122, the gap becomes a slit 124e, 124e, a slit 124e, 124e when the accessory insertion hole 130f adjustment , becomes accessory insertion spacing and number of holes 130f communication.

在分解时,卸下旋钮142,分解了杆部14和手柄部12之后,如图32中所示,把旋转接套130的螺纹部130c插过附件134的主体134a,把突起134b经由前述窄缝124e、124e插入附件插入孔130f中。 When the decomposition, removing the knob 142, after the decomposition of the stem portion 14 and the handle portion 12, as shown in FIG. 32, the rotation of the threaded portion 130 of the sleeve 130c is inserted through the body 134 of the attachment 134a, the protrusion 134b via the narrow slits 124e, 124e is inserted into the insertion hole 130f of the accessory. 借此,旋转接套130的基部130a就不能相对于手柄壳体124旋转。 Whereby rotation of the sleeve 130a of the base 130 can not rotate the handle 124 relative to the housing. 如果在此一状态下用扳手等相对于基部130a拧动螺纹部130c,则旋转接套130在脆弱部130e处破断,位于壳体内部空间内的复位弹簧132可以取出。 If in this state with respect to the base 130a wrench screwing the screw portion 130c, the rotation of the sleeve 130 in the broken at the fragile portion 130e, the return spring located within the internal space of the housing 132 can be removed.
