Please cooperate and consult shown in Fig. 2 and Figure 10-12; On the basis of embodiment three; The present invention also offers draw-in groove 35 on closed clamping plate 3, arc safety plate 89 moving up and down is installed in draw-in groove 35, and the upper end of safety plate 89 is provided with protrusion 892: when this safety plate 89 moves down; Its upper end protrusion 892 contacts with gear wheel 832 engagements of travelling gear 83, stops travelling gear 83 and indicator wheel 84 to rotate revolution; When moving on the safety plate 89, its upper end protrusion separates with travelling gear 83, and travelling gear 83 can reset with indicator wheel 84 revolutions.
Further improvement as present embodiment; Described strap 1 middle part is provided with cotter way and back rotational pin; The front end of closed clamping plate is connected with the back rotational pin, and the rear end of nail supporting base assembly is fixed with preceding rotational pin, and preceding rotational pin can slide up and down and is installed in the cotter way of strap.
Between nail supporting base assembly 2 and back rotational pin, being equipped with can be along the closed sleeve pipe 5 of strap 1 to front slide, and in closed sleeve pipe 5, is provided with jaw locking safety block.Jaw locking safety block is installed on the strap 1 through the compression spring, and when closed sleeve pipe 5 during to front slide, jaw locking safety block can eject and prop up the trailing edge of closed sleeve pipe 5 downwards.And the upper surface of safety plate 89 lower ends and jaw locking safety block offsets, and can between safety plate 89 and strap 1, restoration spring 891 be installed.
More than each embodiment be merely and the present invention is directed to the each several part structure and do improved specific descriptions; Be not to be used to limit protection scope of the present invention; In the practice; Can carry out the combination between each embodiment as required, below the stiching instrument duty with all embodiment Combination application described, further to define technique effect of the present invention and course of action.Need to prove, for course of action clearly is described, will be example with topology layout mode shown in Figure 1 below, and from angle shown in Figure 1, and depression angle is explained the direction of motion of each parts.
During use, apparatus is in original state, and the indicating window Show Color for example is red, and expression band cutter tooth bar is not advanced as yet.Promote earlier closed sleeve pipe 5 forward, strap 1 and nail supporting base assembly 2 closures, the closed and locked safety block in the closed sleeve pipe 5 falls from initial position; Lock closed sleeve pipe 5; Tooth on safety plate 89 and the travelling gear 83 is meshed, and in the percussion process, can prevent travelling gear 83 rollbacks.
Push flexible handle 9; Closed clamping plate 3 rotate thereupon; Push broach connecting rod and sliver 81 that support link 41 promotes to be installed on the closed clamping plate 3 slide to closed clamping plate 3 front ends (being Fig. 1 left-hand), and sliver 81 drives and cooperates the stroke piece of installing 82 to slide synchronously, because stroke piece 82 is provided with toothrow 821 near closed clamping plate 3 one sides; And be meshed with tooth on the gear wheel 832 of travelling gear 83; Stroke piece 82 will drive travelling gear 83 and clockwise rotate (Fig. 1 depression angle), and then be rotated counterclockwise (Fig. 1 depression angle) through pinion 831 drive indicator wheels 84, in the indicating window of apparatus, can be observed the variation of color or pattern; For example be shown as purple, expression percussion is for the first time accomplished.
In this process, the block 88 compression torsion springs of installing on the sliver 81 turn clockwise, and the end face of the limited step 881 of block 88 is equal with sliver 81 surfaces, can be smoothly through set fixture block 91 on the flexible handle 9.
Unclamp flexible handle 9 and reset, can prevent travelling gear 83 and indicator wheel 84 revolutions through safety plate 89, and sliver 81 moves right with respect to stroke piece 82, the extension spring 86 between stroke piece 82 and the sliver 81 is stretched.
In sliver 81 back off procedure; When the block of installing on the sliver 81 88 moves to fixture block 91 the place aheads of flexible handle 9,, can not be rotated counterclockwise because block 88 receives the restriction of block groove 811; At this moment; Fixture block 91 will impose downward power to sliver 81 and stroke piece 82 with the landslide surface of block 88, and stroke piece 82 presses down and supports leaf spring 85.Stroke piece 82 is got back to initial position with respect to sliver 81 under the restoring force effect of the extension spring that is stretched 86.After block 88 broke away from fixture block 91, sliver 81 drove stroke piece 82 and gets back to initial position.
In addition, also can band cutter tooth bar of the present invention be designed to the propulsive structure of substep, push flexible handle 9 and closed clamping plate 3 at every turn; Band cutter tooth bar is all pushed ahead LAP, under the effect of safety plate 89, can guarantee when closed clamping plate 3 reset at every turn; Indicator wheel 84 can not turn round, and pushes closed clamping plate 3 once more, and indicator wheel 84 will continue to rotate (by Fig. 1 depression angle for rotating counterclockwise) according to former direction; Color in the indicating window also can change at any time, with the sign stroke distances.
After percussion was accomplished, the color in the indicating window was for example shown in green, and the expression percussion is accomplished and can be resetted.Earlier jaw is resetted; Jaw locking safety block 84 is by jack-up, and the jack-up safety plate 89 then, makes its upper end protrusion break away from the pawl of travelling gear 83 gear wheels 832; Indicator wheel 84 resets under the effect of torsion spring; Drive travelling gear 83 and get back to initial position, completion resets, and gets back to red color lump in the indicating window and shows.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
