Specific embodiment

Fig. 1 and Fig. 2 are please referred to, it includes one in rifle that those shown, which is that band provided by the utility model fastens parting tool, The shell 1 of shape, front end are equipped with an entrance 11 entered for band, and rear end is equipped with a connector 12, furthermore extend downwardly one again It is available for users to the handle 13 of gripping.

A chipping 2 is pivoted with one first pivot 14 in the shell 1, the chipping 2 is in the delimited on either side of first pivot 14 There are a front end 21 and a rear end 22, and be equipped with a blade 211 to cut off band in front end 21, is equipped with a convex block in rear end 221。

It is equipped with a track for restraining forming by several limited posts 15 in the shell 1, and is equipped with a pull rod 3 in the track, The pull rod 3 can slide along the track.The front end of the pull rod 3 is equipped with a tooth block 31, pulls it to catch on band, the pull rod 3 Rear end one pushing block 4 is pivoted with one second pivot 16, this pushing block 4 is to support the rear end that face 41 is butted on the chipping 2 on one.

The shell 1 is pivoted with a trigger 5 in the front of the handle 13 with a third pivot 18, can be towards close to the handle 13 Direction pivot pendulum.The trigger 5 is equipped with a block 51, and be butted on the pushing block 4 once supports face 42.Accordingly, when detaining the trigger 5 Afterwards, which will push the pushing block 4 backward, and the pushing block 4 is made to pull 3 rearward displacement of pull rod to pull band, and the block 51 push against the pivot pendulum that the pushing block 4 generates opposite second pivot 16 simultaneously, so that the pushing block 4 is pushed 2 pivot of chipping pendulum, and then enable knife Piece 211 cuts off band.The shell 1 is equipped with a reset spring 17 for being butted on the chipping 2 again, after pushing the chipping 2 by the pushing block 4 It can homing.

The distance that band is pulled before cutting determines the degree that article is tightened, and the utility model is by an adjustment mechanism 6 adjustment.The adjustment mechanism 6 includes a hammer 61, a turn-button 62 and an elastic component 63.The hammer 61 is with one the 4th pivot 19 It is hubbed at the shell 1, front side is equipped with a concave-arc part 611, is butted on wherein for the convex block 221 of the chipping 2.The turn-button 62 is hubbed at The connector 12 of the shell 1, and can be rotated in original place at the connector 12.The turn-button 62 is equipped with a jack-post 621 at center, and There is a slope block 622 to be surrounded on around the jack-post 621, which has an angled end-face 623, wherein the angled end-face 623 Height along a hand of spiral be in consecutive variations.

The elastic component 63 is set between the hammer 61 and the turn-button 62, is the spring that one end is coated on outer cylinder.The bullet One end of property part 63 is butted on the angled end-face 623 of the turn-button 62, and the other end is then butted on the rear side of the hammer 61.Accordingly, the hammer 61 press power for pushing and generating the compacting chipping 2 by the elastic component 63, and then the chipping 2 is pushed by the pushing block 4 Caused pivot is put to form obstruction；In other words, which must impose the thrust beginning energy for overcoming the press power enough to the chipping 2 It pushes the chipping 2 to generate pivot pendulum, and then cuts off band.

However the size of the above-mentioned press power is determined according to the position that the elastic component 63 is butted on the angled end-face 623, and the elasticity The position that part 63 is butted on the angled end-face 623 can be by rotating 62 adjustment of turn-button.It is carefully sayed, as shown in Fig. 2, when rotating the turn-button 62 when being butted on the elastic component 63 on the lower position of angled end-face 623, the elastic component 63 generated by lesser compression compared with Small elastic force, thus the strength for pushing against the hammer 61 is smaller, and then the hammer 61 is made to become smaller the press power amount of the chipping 2；Instead It, as shown in figure 5, when rotating the turn-button 62 is butted on the elastic component 63 on the higher position of angled end-face 623, the elastic component 63 are generated biggish elastic force by biggish compression, thus the strength for pushing against the hammer 61 is also larger, and then makes the hammer 61 Become larger to the press power amount of the chipping 2.

By above structure, the utility model in actual use, such as want detaining 5 posterior cord band of trigger need not excessively tight beam Article is cut off person, then can rotate the turn-button 62 as illustrated in fig. 2, make the turn-button 62 with lower position on the angled end-face 623 It sets and is pushed for the elastic component 63, the strength of the hammer 61 of the elastic component 63 pushing and pressing at this time is smaller, pressure of the hammer 61 to the chipping 2 Power processed is also smaller, then only needs to carry out a pivot pendulum more by a small margin as illustrated in fig. 3 after trigger 5 is detained, which pushes The pushing block 4, and then the thrust of the chipping 2 is pushed to be enough that the hammer 61 is overcome to make the chipping 2 to the press power of the chipping 2 Convex block 221 is detached from the concave-arc part 611 of the hammer 61 and generates pivot pendulum, and enables the cutting band 7 as illustrated in fig. 4 of blade 211 whereby.

On the other hand, such as want to be cut off again by lasting tension with girding articles detaining 5 posterior cord band of trigger still, then it can be such as The turn-button 62 is rotated as shown in Figure 5, pushes the turn-button 62 for the elastic component 63 with higher position on the angled end-face 623, this When the elastic component 63 push against the hammer 61 strength it is larger, the hammer 61 is larger to the press power of the chipping 2, then in 5 quilt of trigger A pivot pendulum by a relatively large margin must be carried out after detaining as illustrated in fig. 6, the block 51 can be enabled to push the pushing block 4, and then pushing should The thrust of chipping 2 is enough to overcome the hammer 61 to the press power of the chipping 2, and the convex block 221 of the chipping 2 is made to be detached from the hammer 61 Concave-arc part 611 and generate pivot pendulum, and enable whereby blade 211 as illustrated in fig. 7 cutting band 7.

Furthermore as shown in Fig. 1, Fig. 8, the circumferential surface of the jack-post 621 of the turn-button 62 is equipped with a plurality of positioning depressions 624, and is somebody's turn to do Shell 1 be equipped with one include spring and steel ball flexible positioning piece 625 be embedded in it flexibly by spring push steel ball In one of positioning depression 624, the turn-button 62 is fixed, accordingly so that the elastic component 63 is firmly butted on the angled end-face 623. It is equipped with a mark face 626 around the turn-button 62 again, the position for corresponding to each positioning depression 624 is respectively equipped with a beacon information, can User is provided and browses the adjustment state for recognizing the turn-button 62.

The utility model has the advantage of the component configurations using less component and simplification can reach adjustment band beam The function of tight degree, can reduce the technical difficulty of material cost and assembling, and the utility model is utilized when rotating the turn-button 62 The angled end-face 623 pushes the elastic component 63, and can be operationally more laborsaving, uses upper convenience to be promoted.
