One end is provided with through hole 22, and main shaft 30 is articulated with the through hole 22.Specifically, the main shaft 30 of the present embodiment is removably articulated with
The through hole 22, blade 20 have and can only rotated around the main shaft 30 so as to ensure the rotation direction of blade 20.When by outer
When power presses the knife back, the blade 20 first overcomes the elastic stress of shell fragment 80 so that steel ball 70 and the positioning close to quick-opening device 24
Hole 21 separates, and now steel ball 70 is resisted against blade 20, and blade 20 can rotate around main shaft 30 along close to the direction of bayonet socket 11, until remote
The positioning hole 21 of quick-opening device 24 can position when being absorbed in steel ball 70 to blade 20.In addition, the groove spacer sleeve 50 is now
Available for the further extreme position for limiting blade 20 and being folded in bayonet socket 11.
For the expanded position of effective control blade 20, the blade 20 of the present embodiment needs effectively to be resisted against stop bit nail
40。
As shown in Figure 3 and Figure 4, it is preferred that in order to effectively ensure the expanded position of blade 20, the blade 20 is close to main
One end of axle 30 is provided with locating slot 23, and locating slot 23 is used for the position for limiting the expansion of blade 20.Specifically, the blade of the present embodiment
20 are provided with locating slot 23 close to one end of main shaft 30；When by quick-opening device 24 described in pressed by external force, first gram of the blade 20
The elastic stress of shell fragment 80 is taken so that steel ball 70 separates with the positioning hole 21 away from quick-opening device 24, now steel ball 70 is resisted against knife
Piece 20, blade 20 can rotate around main shaft 30 along away from the direction of bayonet socket 11, until the positioning hole 21 close to quick-opening device 24 is absorbed in steel
Blade 20 can be positioned during pearl 70, so simultaneously, the locating slot 23 offsets further to limit knife with stop bit nail 40
The position that piece 20 deploys.
To make the steel ball 70 be held against in the blade 20, the one end of the shell fragment 80 of the present embodiment away from steel ball 70
Need to be fixed on handle 10.
As shown in Figure 2 and Figure 5, it is preferred that use space to reduce, the handle 10 is provided with mounting groove 17, shell fragment 80
Mounting groove 17 is removably fixedly arranged on by connector 60.Specifically, the handle 10 of the present embodiment is dug on own material
Go out a mounting groove 17, shell fragment 80 stretch into the one end of the mounting groove 17 and shell fragment 80 away from steel ball 70 by connector 60 with
Removably is fixedly arranged on to mounting groove 17.Quick-opening device 24 described in the present embodiment is provided with slotted eye 25, when blade 20 is folded in
After bayonet socket 11, the slotted eye 25 can be clasped by external member can be easily accomplished carrying.As can be seen here, by provided with shell fragment
80, and the one end of shell fragment 80 is provided with the steel ball 70 for being used for being resisted against blade 20, and the other end is fixedly arranged on mounting groove 17 and used
Above-mentioned technical proposal, this can realize without lock jack knife and blade 20 is effectively positioned by self-locking manner.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
