Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in figs. 1-13, a kind of tie gun that can regulate the dynamics of tightening, comprise main body 1, handle 11 and shoutoff mechanism, main body 1 rear portion is connected with upper cover 2, handle 11 and main body 1 pin joint, be connected with the 3rd connecting strap 13 one end in the middle part of handle 11, 3rd connecting strap 13 other end is connected with in the middle part of the second connecting strap 12, second connecting strap 12 top is connected with spring leaf 14, second axis of rolling 34 of the second connecting strap 12 bottom is arranged on main body 1 side, spring leaf 14 side is connected with returning spring 35, also comprise strength adjusting mechanism, strength adjusting mechanism comprises curved pin 15, in the middle part of curved pin 15, pin joint on the body 1, first axis of rolling 33 that first connecting strap 10 lower end connects is arranged in the groove of curved pin 15, first adjustment sheet 10 upper pin connects on the body 1, the adapter shaft of the first adjustment sheet 10 left end is arranged in the U-type groove 25 of knife bar 5 end, knife bar 5 pin joint on the body 1, be arranged on below blade 4 on the left of knife bar 5, up-down adjustment mechanism is connected with on the left of curved pin 15.
Utility model works principle is as follows: shoutoff mechanism comprises blade, and band can cut off by blade.Up-down adjustment structure, by manual control, can move up and down.When up-down adjustment mechanism moves up time, curved pin 15 is driven to rotate clockwise around bearing pin 32, curved pin 15 drives the first axis of rolling 33 run-off the straight displacement to the right, now, the adapter shaft on the left of the first connecting strap 10 moves down accordingly, drives the rotation that knife bar 5 is slight clockwise, now move up on the left of knife bar 5, and be arranged on bottom blade 4 on knife bar 5, knife bar 5 is with cutting blade 4 slightly to move up, and then can improve the dynamics that blade cuts off wire harness.When needs reduce blade dynamics time, move down up-down adjustment mechanism.
As preferably, described up-down adjustment mechanism comprises tension bar 18, tension bar 18 lower end is through stretching in the blind hole of adjusting knob 21 after the through hole on elastic force seat 16 and the through hole on adjusting knob 19, adjusting knob 21 sidewall is provided with puller bolt 22, tension bar 18 overcoat has outside little spring 30, little spring 30 and is provided with big spring 31, and fixed support 17 is through the groove of elastic force seat 16 both sides.
Up-down adjustment mechanical work principle is as follows: tighten puller bolt 22, rotation of adjustment knob 21, adjusting knob 21 is made to drive tension bar 18 to move up, tension bar 18 upper end is provided with the through hole 29 be connected with curved pin 15, tension bar drives curved pin 15 to rotate clockwise around bearing pin 32, and then blade is moved up.When blade position is adjusted to the right place, just accurately can control dynamics, now unclamp puller bolt 22, even if adjusting knob 21 is rotated in workman's maloperation, the position of blade also can not change again, and then makes the strength of tightening of tie gun be in locking state.Make binding force in production process relatively more even, bad product can not be caused.Wherein, big spring 31 and little spring 30 can guarantee the position of trickle adjustment blade, and blade, applying when application force band, displacement a little can occur, and big spring 31 and little spring 30 can reset blade in time.Registration mast 28 on elastic force seat 16 can spacing little spring.
As preferably, described strength adjusting mechanism also comprises locking mechanism, locking mechanism comprises the first fixed block 23 be fixed on bottom main body 1, first fixed block 23 is connected with spring pin 36, spring pin 36 bottom contacts with the second fixed block 24, and the spacing preiection 27 of the second fixed block 24 end is arranged in the teeth of adjusting knob 21 sidewall.Spring pin 36 holds out against the second fixed block 24, makes spacing preiection 27 snap in adjusting knob 21 sidewall, can prevent adjusting knob 21 from arbitrarily rotating like this, also can prevent adjusting knob 21 from reversing.
Shoutoff mechanism in the utility model comprises blade 4, blade 4 is arranged in the cavity of the rifle headrest 3, blade 4 is provided with the protruding 4-1 of blade, and the protruding 4-1 of blade is just in time stuck in the blade groove 3-1 of the rifle headrest 3, and one end of blade 4 is placed on the step 3-2 on the rifle headrest 3.The left side edge of blade groove 3-1 can change to the distance L of the rifle headrest 3 leftmost side, and on each rifle headrest 3, distance L can arrange difference, to adapt to the requirement of arrowband to different length in reserve.Do not fix between blade 4 and the rifle headrest 3, can change arbitrarily, countersunk bolts runs through the counterbore on the rifle headrest 3 and the connecting bore 26 in main body 1, the rifle headrest and main body is coupled together, and is linked up by M3 bolt and main body by two other fixed orifice.By adjusting the different rifle headrests, just different length can be reserved to band.And the replacing of the rifle headrest is more convenient, blade 4 is general.Generally, L can be 1,2,3,4 or 5mm.Wherein, the second catch 8 is connected with pull bar 9, and the first catch 7 is in stay side.
In the utility model, on handle 11, cover has taper knob 20, shoutoff mechanism use principle is as follows: inserted in the teeth of stay 6 by the groove of band by end, pull handle 11, be connected in the middle part of handle 11 with the 3rd connecting strap 13, can not move, therefore handle 11 rotates around the bearing pin of top, and drive spring leaf 14 to be moved to the left, spring leaf 14 drives pull bar 9 to be moved to the left, pull bar 9 promotes blade 4 and works, and is cut off by band.After release handle 11, under the effect of returning spring 35, pull bar 9 and blade 4 automatically return to original position, ready for working next time.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
