End is equipped with anti-slip part 71, and the setting of anti-slip part 71, which is convenient for taking, holds；The setting of rumpbone 7 on the one hand can be by the first side handle 21 and second
Side handle 22 is fixedly connected, and the holding tank 24 of receiving is provided for blade 1, on the other hand to when blade 1 is accommodated in holding tank 24,
Rumpbone 7 plays the role of limit, and blade 1 is avoided to store excessively.
23 front end of elastic arm is provided with steel part 231 of the tip far from handle of a knife 2 for supporting blade 1, and blade 1 is equipped with and steel
The third groove 101 that part 231 is adapted to, when blade 1 is accommodated in handle of a knife 2, the steel part 231 on elastic arm 23 is connected to third groove
When in 101, blade 1 just cannot take out from handle of a knife 2 easily.
It is provided with first bearing retainer 8 between first side handle 21 and blade 1, is arranged between the second side handle 22 and blade 1
There is second bearing retainer 9；It is embedded with ball 10 on first bearing retainer 8 and second bearing retainer 9；First axle is accepted insurance
Holder 8, second bearing retainer 9 are socketed on main shaft mother nail 3, the setting of first bearing retainer 8, second bearing retainer 9
It is rotated convenient for blade 1, also functions to the effect of buffering.
First bearing seat 11, second bearing retainer 9 and are provided between first side handle 21 and first bearing retainer 8
Second bearing seat 12 is provided between two side handles 22, first bearing seat 11 and second bearing seat 12 play the role of fastening.
First side handle 21 is horizontally connected with only close to one end of blade 1 and the second side handle 22 between one end of blade 1
Position nail 13；Blade 1 is equipped with the position-arresting groove 102 for being embedded in stop bit nail 13；When blade 1 turns to expansion position, the first position-arresting groove
102 abut with the first stop bit nail 13, and blade 1 just cannot be rotated further, and the side of handle of a knife 2, which is further fixed on, embraces folder 14.
In addition, main shaft nail 4 includes interior nail and outer nail, interior nail is set in inside outer nail, also, real between interior nail and outer nail
It now relatively rotates, main shaft mother nail 3 is inserted into outside described and nails on, and interior nail is fixedly connected with the first gear 151, and quilt is followed closely in external force
When rotation, interior nail and first gear 151 are realized and are rotated synchronously so that first gear 151 drives the second tooth by third gear 153
Wheel 152 is rotated, so that second gear 152 drives crawler belt item 1121 in accommodating chamber back-and-forth motion, i.e. first gear 151
Passing sequentially through third gear 153, second gear 152 and crawler belt item 1121 drives second page 112 to be moved forward and backward in accommodating chamber, can
It is very convenient to increase the length of blade 1.
When using the present invention, due to including blade 1 and handle of a knife 2, wherein blade 1 is hinged with handle of a knife 2 so that blade 1
It is rotated around handle of a knife 2, and blade 1 includes first page 111, second pages 112 and gear sets, the molding in first page 111
Having accommodating chamber, (first page 111 includes first shell 1111 and second shell 1112, first shell 1111 and second shell 1112
It is superimposed with each other together, also, the accommodating chamber is formed between first shell 1111 and second shell 1112), and second page
112 are set in first page 111, also, first page 111 is slidably connected with second page 112 so that second page
112 can slide (i.e. second page 112 slides in the accommodating chamber of first page 111) in first page 111, at second
112 one end of page form crawler belt item 1121, in addition, gear set includes first gear 151, second gear 152 and third gear
153, moreover, first gear 151, second gear 152 and third gear 153 are rotatably installed in (i.e. tooth on first shell 1111
Wheel group is rotatably arranged in first page 111 and in accommodating chamber), first gear 151 and third gear 153 are intermeshed,
Also, the second gear 152 is intermeshed with third gear 153, and second gear 152 engages connection with crawler belt item 1121
(i.e. first gear 151, third gear 153, second gear 152 and crawler belt item 1121 engage successively), first gear 151 is rotated
When, first gear 151 drives second gear 152 to be rotated by third gear 153, so that second gear 152 drives
Crawler belt item 1121 is moved forward and backward in accommodating chamber, i.e., first gear 151 passes sequentially through third gear 153, second gear 152 and crawler belt
Item 1121 drives second page 112 to be moved forward and backward in accommodating chamber；When needing to adjust the length of blade 1, external force so that interior nail is turned
Dynamic, interior nail and first gear 151 realize and rotate synchronously that, that is, so that first gear 151 is rotated, first gear 151 passes sequentially through
Third gear 153, second gear 152 and crawler belt item 1121 drive second page 112 to be moved forward and backward in accommodating chamber, to increase knife
The length of piece 1, it is the case where avoiding " long blade " from must be equipped with " long-cutter holder ", very convenient.It can solve jack knife in the prior art
The length of structure is long, inconvenient to carry, alternatively, decreased food is too short, uses also dangerous, inconvenient problem.Separately
Outside, the both ends that the fastener 5 of the first side handle 21, elastic arm 23 and the second side handle 22 is connected on the jack knife are inlaid in the first side handle respectively
21, in the second side handle 22, while fastener 5 fixes the first side handle 21, elastic arm 23 and the second side handle 22, also it is hidden in the first side
