The specific embodiment
See also Fig. 1, shown in Figure 2, the steel wire rope coupling assembling of this utility model band cutter stiching instrument mainly comprises contiguous block 61, connects steel wire rope 62 and snap close fixture 63.Wherein, the profile of contiguous block 61 is preferably cube shaped, and inside is divided into left chamber 611 and right chamber 612 through interlayer.
Connect steel wire rope 62 and penetrate 611 inside, left chamber, and on the termination that is positioned at contiguous block 61 inside, pushing block 621 is set, between this pushing block 621 and the left chamber 611 left walls bit shift compensation spring 64 is installed from contiguous block 61 left ends.
Snap close fixture 63 is installed in the right chamber 612 of contiguous block, and right chamber 12 right-hand members are provided with the snap close loading hatch, and between snap close fixture 63 and right chamber 612 left walls, are equipped with mounting spring 65.
Preferable, please cooperate and consult shown in Figure 3ly, the cube cavity can be adopted in left chamber 611, the rectangular block of pushing block 621 for matching with left chamber 611 shape of cross sections.The left part in chamber 611, a left side can be provided with a pair of limited step 613, is used for limiting the relative displacement distance of pushing block 621, guarantees that the preceding cutter assembly of percussion is in the initial position in the gathering sill all the time.Because when band cutter stiching instrument was closed, the closed size of jaw was 18-19mm, the nail bin groupware advances 18-19mm, therefore, the relative displacement between pushing block 621 and the contiguous block 61 is arranged between the 5-20mm, can guarantee to replenish corresponding displacement.
The right chamber 612 of contiguous block is preferably cylindrical cavity, and on 612 sidewalls of right chamber, offers chute 614, and the card protruding 615 that coincide with mounting spring 65 internal diameters is set on the left wall in right chamber 612.The snap close loading hatch comprises in the middle of the 612 right walls of right chamber offers the draw-in groove 616 to sidewall, and is positioned at the company's cutter Steel wire rope lock that is communicated with this draw-in groove 616 on the sidewall of right chamber and buckles into mouth 617.
Please cooperate and consult shown in Figure 4ly, snap close fixture 63 outer walls and right chamber 612 inwalls match, and are provided with the sliding pin 631 that leans out right chamber chute 614.Snap close fixture 63 right parts are provided with the cavity 632 that matches with the snap close that connects the cutter steel wire rope, the mounting groove 633 that left part is provided with and mounting spring 65 external diameters coincide, and mounting spring 65 promptly installs and fixes with mounting groove 633 through blocking protruding 615.
Please cooperate and consult shown in Figure 5ly, this utility model band cutter stiching instrument comprises the steel wire rope coupling assembling 6 of nail supporting base 1, nail bin 2, cutter assembly 3, propulsive mechanism 4, draw-off mechanism 5 and this utility model.Wherein, the connection steel wire rope 62 of steel wire rope coupling assembling 6 is positioned at the outer end of contiguous block and docks with the tractive steel wire rope 51 of draw-off mechanism 5, and company's cutter steel wire rope 32 snap close ends of cutter assembly 3 are installed in the right chamber 612 of contiguous block of steel wire rope coupling assembling 6.
Specifically, connect cutter steel wire rope 32 1 ends and be fixed on the cutting knife slide block of nail bin groupware 3, the other end is the free end that has snap close, is fixed on during use in the right chamber 612 of contiguous block of steel wire rope coupling assembling 6.Tractive steel wire rope 51 1 ends are fixed on the tooth bar of draw-off mechanism 5, and the other end is a free end, are positioned at the outer end of contiguous block and connect through frock with the steel wire rope 62 that is connected of steel wire rope coupling assembling 6 during installation.Connect in the chamber 611, a contiguous block left side that steel wire rope 62 is arranged on steel wire rope coupling assembling 6, an end is fixed on the pushing block 621, and the other end is a free end, during use and the free end of tractive steel wire rope 51 connect, fix through frock.Above-mentioned three sections steel wire ropes are all selected flexible wire ropes for use, after cooperatively interacting and connecting, make promotion, draw-off mechanism can drive nail bin, cutter assembly motion.
During installation; Earlier mounting spring 65 1 ends are fixed in the mounting groove 633 of snap close fixture 63; The snap close fixture 63 that will have a mounting spring 65 is installed in the right chamber 612 of fixed block, and the other end of mounting spring 65 is fixed on the card protruding 615, and the sliding pin 631 of snap close fixture 63 is installed in the right chamber chute 614; Snap close fixture 63 can move snap close fixture 63 through 631 compression or the stretching mounting spring of the sliding pins in the chute 614 to the left or to the right at this moment.
Afterwards, bit shift compensation spring 64 be installed in connect on the steel wire rope 62, again with its integral installation in chamber 611, a contiguous block left side, will have the connection steel wire rope 62 and 51 butt joints of tractive steel wire rope of pushing block 621, use aluminium alloy dog or snap close to fix.
Please cooperate and consult Fig. 6, shown in Figure 7; When nail bin groupware was installed, at first manually sliding pin 631 was moved to the left snap close fixture 63 compression mounting spring 65; The free end of company's cutter steel wire rope 32 that will be connected with nail bin groupware; Laterally pushed by snap close inlet 617, until the end position that arrives draw-in groove 616, snap close is stuck in the right chamber 612 of contiguous block.This moment, the releasable catch fixture 63, and the snap close that connects on the cutter steel wire rope 32 is urged in the cavity 632 of bottom surface, snap close fixture 63 right side.
When changing nail bin, the manually right sliding pin 631 of dialling is moved to the left through snap close fixture 63 compression mounting spring 65; Used nail bin groupware is connected the snap close end of cutter steel wire rope 32, will connect cutter steel wire rope 32 along draw-in groove 616 and snap close inlet 617 and take out, thereby shift out nail bin groupware; After a while new nail bin groupware is connected the right chamber 612 of snap close propelling contiguous block of cutter steel wire rope, releasable catch fixture 63 is again at suture head; Other nail bin groupwares are installed, are promptly accomplished the replacing operation of nail bin.
During use, before band cutter stiching instrument closure, pushing block 621 is positioned at 611 right sides, chamber, a fixed block left side.Push pedal 41 promotion nail bin groupwares through propulsive mechanism 4 move forward; Reach complete closure; In this course of action; The end that connection steel wire rope 62 is positioned at outside the contiguous block 61 is fixed, and contiguous block 61 moves right under the pulling function that connects cutter steel wire rope 32, and the bit shift compensation spring 64 that is positioned at left chamber 611 is compressed.Behind the limited step 613 in pushing block 621 arrives at left chamber 611, the coupling assembling 6 integral body 18-20mm that relatively moved forward is with the cutter stiching instrument closed fully this moment.Afterwards, spur tractive steel wire rope 51, connect steel wire rope 62, further spur coupling assembling 6, connect cutter steel wire rope 32, carry out the cutting and stitching operation thereby can drive cutter assembly 3 through draw-off mechanism 5.
When resetting, press the SR of stiching instrument, apparatus is got back to original state; Jaw and separate tissue, compressed bit shift compensation spring 64 obtain restoring, and coupling assembling 6 relatively moves left; Pushing block 621 leaves limited step 613, comes back to the right side in chamber 611, a contiguous block left side.
The above; It only is the preferred embodiment of this utility model; Be not that this utility model 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 the protection domain of this utility model.
