This utility model purpose is to solve above-mentioned technical problem, and a kind of resetting-mechanism of Linear stapling cutter simple in structure is provided.
The technical solution of the utility model is:
A kind of resetting-mechanism of Linear stapling cutter, the tooth bar that comprises the traction piece that resets, the rollback pull bar that is connected with the described traction piece that resets, can be dynamically connected with described rollback pull bar, also comprise the reseting plate of integrated molding and the drag hook that resets, the described drag hook that resets vertically is convexly set on described reseting plate, there is an end of a reset tension spring to catch on the described drag hook that resets, the other end of described reset tension spring catches on the extension spring of described Linear stapling cutter and buckles, and the lower surface of described reseting plate is the contact surface with the vertically only lock dog of described Linear stapling cutter.
Preferably, described extension spring button is arranged on the tooth bar of described Linear stapling cutter.
Preferably, the described drag hook that resets is located at the top of described tooth bar.
Preferably, connect on described reseting plate and be provided with at least one guide groove that resets, the side of described tooth bar convexes with at least one pilot pin, and described pilot pin extend in the described guide groove that resets.
Preferably, connect on described reseting plate and be provided with opening, described rollback pull bar extend in the opening of described reseting plate.
The beneficial effects of the utility model are: reseting plate and the drag hook that resets is one-body molded, simple and reliable for structure, easy to assembly, and cost.

Wherein: 1, reseting plate; 2, the drag hook that resets; 3, the guide groove that resets; 4, reset tension spring; 5, opening; 6, extension spring button; 7, pilot pin; 8, vertically stop lock dog; 9, spring; 10, rollback pull bar; 11, percussion handle; 12, ratchet; 13, the traction piece that resets; 14, tooth bar.
The specific embodiment
Embodiment one: referring to illustrated in figures 1 and 2, this utility model provides a kind of resetting-mechanism of Linear stapling cutter, the tooth bar 14 that comprises the traction piece 13 that resets, the rollback pull bar 10 that is connected with the described traction piece that resets, can be dynamically connected with described rollback pull bar, and the reseting plate 1 of integrated molding and the drag hook 2 that resets.The described drag hook 2 that resets vertically is convexly set on described reseting plate 1.The lower surface of described reseting plate 1 is the contact surface with the vertically only lock dog 8 (shown in Figure 3) of described Linear stapling cutter.Because reseting plate 1 and the drag hook 2 that resets are metal material, therefore can adopt the mode of stepping punching press to realize one-body molded.Certainly, if reseting plate 1 and the drag hook 2 that resets are plastic material, can adopt integrated injection molding.
Have an end of a reset tension spring 4 to catch on the described drag hook 2 that resets, the other end of described reset tension spring 4 catches on the extension spring button 6 of described Linear stapling cutter, and described extension spring button 6 is arranged on the tooth bar 14 of described Linear stapling cutter.The described drag hook 2 that resets is located at the top of described tooth bar 14.
In conjunction with Fig. 3, shown in Figure 4, connect on described reseting plate 1 and be provided with at least one guide groove 3 that resets, the side of described tooth bar 14 convexes with at least one pilot pin 7, and described pilot pin 7 extend in the described guide groove 3 that resets.The described guide groove 3 that resets is oblique lower setting.Connect on described reseting plate 1 and be provided with opening 5, the part of the rollback pull bar 10 of described Linear stapling cutter extend in described opening 5.
The below simply describes operating process of the present utility model.
As shown in Figure 3, the ratchet 12 on percussion handle 11 drives tooth bar 14 and advances, the high position during described reseting plate 1 is in Fig. 3 all the time under the effect of reset tension spring 4 at this moment, and namely described reseting plate 1 is not interfered the intermeshing of tooth bar 14 and vertical only lock dog 8.Because a vertical only side of lock dog 8 is subject to the effect of spring 9, so its engagement with tooth bar 14 can stop tooth bar 14 rollbacks, and this hour rack 14 is in and stops lock status.
As shown in Figure 4, after the Linear stapling cutter percussion was complete, rollback pull bar 10 drove reseting plate 1 and moves backward, and meanwhile reseting plate 1 moves down again under the effect of reset guide groove 3 and pilot pin 7, reaches like this low level in Fig. 4.The active force that the lower surface of described reseting plate 1 forces described vertical only lock dog 8 to overcome spring 9 moves down, thereby make described vertically only lock dog 8 and tooth bar 14 disengagements, the tooth bar 14 of this moment is not subjected to vertically only stopping of lock dog 8, pulls the traction piece 13 that resets can make the smooth rollback of tooth bar 14.
This utility model still has numerous embodiments, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the claimed scope of this utility model.
