As shown in fig. 7, 8, and 9, the middle leg 702 is movable relative to the sheath 701 between a first position i (see fig. 7) and a second position ii (see fig. 8 and 9). As shown in fig. 7, when the middle support 702 is at the first position i, the friction end 806 of each damping member 801 is located in the first relief section 711 of the corresponding first relief groove 710, and the middle support elastic member 704 (see fig. 6) is compressed and has a potential to move the middle support 702 from the first position i to the second position ii. As shown in fig. 8 and 9, when the middle support 702 is in the second position ii, the friction end 806 of each damping member 801 contacts with one of the first chamfer portion 713 and the first friction surface portion 714 of the inner side surface 709 of the corresponding outer side wall 706, and as shown in fig. 8, when the middle support 702 is at the starting point of the stroke in the second position ii, the friction end 806 of each damping member 801 contacts with the first chamfer portion 713 of the inner side surface 709 of the corresponding outer side wall 706. As shown in fig. 9, during the movement of the middle leg 702 toward the end of the stroke of the second position ii, after the friction end 806 of each damping member 801 is separated from the first chamfer portion 713 of the inner side surface 709 of the outer side wall 706, the friction end 806 of each damping member 801 is in contact with the corresponding first friction surface portion 714 of the inner side surface 709 of the outer side wall 706. In the present embodiment, the first relief section 711 of the first relief groove 710 of each outer sidewall 706 is hollow, so when the middle support 702 is at the first position i, the friction end 806 of each damping member 801 does not contact with the inner side surface 709 of the corresponding outer sidewall 706, but not limited thereto, in other variations of the present embodiment, the first relief section 711 of the first relief groove 710 of each outer sidewall 706 may also be formed by protruding the inner side surface 709 outward to be non-hollow, the friction end 806 of each damping member 801 slightly contacts with the inner side surface 709 of the corresponding outer sidewall 706, and the buffering elastic member 802 is not compressed.
As shown in fig. 3, the operating unit 80 is operatively connected to the center leg 702 and selectively positions the center leg 702 at the first position i. In this embodiment, the operation unit includes a button 81 and a positioning element 82 connected to the button 81, the positioning element 82 can hook the middle support 702 by the front end, when the user wants to eject the middle support 702, the user can press the button 81 to drive the rear end of the positioning element 82, so that the front end of the positioning element 82 is separated from the middle support 702, and at this time, the middle support 702 can be ejected forward by the elastic restoring force of the middle support elastic element 704.
Therefore, in the process of moving the middle support 702 from the first position i to the second position ii, firstly, the first relief section 711 of the first relief groove 710 of the outer sidewall 706 is used for allowing the friction end 806 of the damping member 801 to freely move, so that the middle support 702 is not subjected to resistance during initial ejection, furthermore, the first inclined guide surface 713 of the inner side surface 709 of the outer sidewall 706 is used for enabling the friction end 806 of the damping member 801 to smoothly enter the second position ii from the first position i, and finally, the friction force between the damping member 801 and the inner side surface 709 of the outer sidewall 706 is used for generating a buffering effect, so that the speed and force for ejecting the sheath 701 from the middle support 702 can be reduced, and the safety of a user during use can be improved.
As shown in fig. 10 and 11, a second embodiment of a stapler with a buffering mechanism according to the present invention, similar to the first embodiment, is mainly different in that:
in this embodiment, the damping module 800 has two damping members 801 and a damping elastic member 809 disposed between the damping members 801, and each damping member 801 has only the shoulder 803 and the outer rod 804. The shoulder 803 has an inner side surface 807 opposite to the outer rod 804, an outer peripheral surface 808 connected to the inner side surface 807, and a locking groove 810 formed in the inner side surface 807. The locking groove 810 has a horizontal section 811 extending outward from the inner side surface 807 in the transverse direction Y, and a vertical section 812 extending upward from the horizontal section 811 to the outer peripheral surface 808. The elastic buffer member 809 has a bent curved section 813 and two positioning sections 814, the curved section 813 has two opposite ends 815, the positioning sections 814 are respectively connected to the ends 815 and extend outward along the transverse direction Y, each positioning section 814 is embedded in the horizontal section 811 of the corresponding slot 810 of the damping member 801, and each end 815 is embedded in the vertical section 812 of the corresponding slot 810 of the damping member 801.
In this way, the second embodiment can achieve the same purpose and effect as the first embodiment, and in addition, by the shape design of the bending portion 813 of the buffering elastic member 809, the interference between the mandrel 705 and the buffering elastic member 809 can be avoided, so the buffering module 800 of the second embodiment can be applied to the middle support module 700 of the stapler with smaller overall design space.
As shown in fig. 12 and 13, a third embodiment of a stapler with a buffering mechanism according to the present invention, similar to the second embodiment, mainly differs in that:
each of the outer sidewalls 706 of the sheath 701 further has a second relief groove 717 formed on the inner side surface 709 and located in front of the first relief groove 710 in the long direction X. The second receding groove 717 has a second rear guiding slanting section 718, and a second receding section 719 communicating with the second rear guiding slanting section 718 and located in front of the second rear guiding slanting section 718. The inner side surface 709 also has a second back guiding inclined surface portion 720 defining an outer side of the second back guiding inclined section 718 and extending forward and outward from the first friction surface portion 714. A distance between the second back chamfer portion 720 of the inner side surface 709 of the outer sidewall 706 increases gradually from back to front.
As shown in fig. 14 and 15, when the middle support 702 is in the second position ii, during the forward movement of the middle support 702, the friction end 806 of each damping member 801 is in contact with the corresponding first chamfer portion 713, the first friction surface portion 714 and the second back chamfer portion 720 of the inner side surface 709 of the outer side wall 706 in sequence. In this embodiment, the middle support 702 can also move to a third position iii relative to the sheath 701, and when the middle support is in the third position iii, the friction end 806 of each damping member 801 is located in the second relief section 719 of the corresponding second relief groove 717 and does not contact the inner side surface 709 of the corresponding outer side wall 706. The second relief groove 717 disposed on each outer sidewall 706 allows the user to easily pull out the middle support 702 to the end of the travel of the third position iii (see fig. 15). Thus, the third embodiment can achieve the same purpose and effect as the second embodiment described above, and it can be understood that when the user pushes the middle support 702 back, the friction end 806 of the damping member 801 can be smoothly moved from the third position iii to the second position ii by the second rear inclined surface portion 720 of the inner side surface 709 of the outer side wall 706.
As shown in fig. 16 and 17, a fourth embodiment of a stapler with a buffering device according to the present invention, similar to the third embodiment, mainly differs in that:
the second relief groove 717 of each outer sidewall 706 further has a second leading inclined section 721 communicated with the second relief section 719 and located in front of the second relief section 719, and a friction section 722 communicated with the second leading inclined section 721 and located in front of the second leading inclined section 721. The inner side surface 709 of each outer side wall 706 further has a second leading inclined surface portion 723 defining an outer side of the second leading inclined section 721, and a second friction surface portion 724 defining an outer side of the friction section 722. A distance between the second front inclined plane portions 723 of the inner side surface 709 of the outer side wall 706 gradually decreases from the rear to the front, and a distance between the second friction surface portions 724 of the inner side surface 709 of the outer side wall 706 is larger than a distance between the first friction surface portions 714.
In this embodiment, the middle leg 702 can also move to a fourth position iv relative to the sheath 701, when the middle leg 702 is at the fourth position iv, the friction end 806 of each damping member 801 sequentially contacts with the second front inclined surface portion 723 and the second friction surface portion 724 of the inner side surface 709 of the corresponding outer side wall 706 during the forward movement of the middle leg 702. Thus, the fourth embodiment can achieve the same purpose and effect as the third embodiment.
In summary, the stapler with the buffering device of the present invention can utilize the friction force between the damping member 801 and the inner surface 709 of the outer sidewall 706 to generate the buffering effect, so as to slow down the speed and force of the middle support 702 ejecting the sheath 701, so that the user can use the stapler more safely, thereby achieving the purpose of the present invention.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
