The further improvement is that: the lower clamping rod is fixedly arranged on the positioning block through threaded connection.
The further improvement is that: go up the supporting rod and include connecting rod and supporting rod body, the supporting rod body passes through the screw thread and is connected with the connecting rod, the connecting rod other end is located on the locating piece.
The further improvement is that: the rack is provided with a sliding groove, the positioning part is fixedly provided with a sliding rail clamped with the sliding groove, and the sliding rail is also connected with a linkage rod which enables the positioning blocks at two ends to be linked.
The further improvement is that: and a hand wheel is arranged on the first screw rod.
The utility model has the advantages and the beneficial effects that:
1. simple structure, can fix a position the product, when the product got into the conveying cylinder of frame, last supporting rod on the positioner can carry out the centre gripping location with lower supporting rod to the product, guarantees that the product can be in the cutting position in the cutting, prevents that the cutting from giving unqualified product.
2. The distance between supporting rod and the lower supporting rod can be adjusted to the roll adjustment device, not only can make the product stack the centre gripping simultaneously, then cut, but also can fix a position corresponding to the product of different thickness, has improved the efficiency and the practicality of cutting greatly.
3. The rubber block can prevent the clamping rod from damaging the product during clamping.
4. Go up the supporting rod and set up with lower supporting rod dismantled and assembled respectively, make it can match different product sizes, and then change its length, make it have more the practicality.
5. The cooperation of spout and slide rail can make the more smooth and easy slip in the frame of locating piece, and the trace can make the positioner at both ends remove simultaneously, has further guaranteed the accuracy of product cutting position, improves the qualification rate of product.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-2, a fashioned cutting device of lunch-box includes frame 1, be equipped with the conveying cylinder 2 that is used for carrying the product in frame 1, both ends symmetry is equipped with the positioner who is used for fixing a position the product in frame 1, positioner includes: locating piece 3 in frame 1 is located in the slidable, be equipped with down supporting rod 8 on the locating piece 3, be equipped with on the locating piece 3 and be used for with the cooperation of lower supporting rod 8 with the fixed elastic last supporting rod 4 that takes of product, still be equipped with in the frame 1 and be used for the drive the gliding slider of locating piece 3, slider includes rotatable first screw rod 5 of locating in frame 1, first screw rod 5 wears to locate on the locating piece 3, locating piece 3 can with the transmission of first screw rod 5 meshing. Wherein, when the product got into the conveying cylinder 2 of frame 1, align the product both ends respectively, then break off from the fingers and thumb clamping rod 4, put the product on clamping rod 8 down, then loosen clamping rod 4, make the product centre gripping last clamping rod 4 and down on clamping rod 8, then rotate first screw rod 5, first screw rod 5 and the meshing transmission of locating piece 3, locating piece 3 slides on frame 1, drives the product and removes on conveying cylinder 2, then cuts the product.
In order to accelerate the cutting efficiency and fix a position the product that corresponds different thickness, still be equipped with the roll adjustment device that is used for adjusting last supporting rod 4 and lower supporting rod 8 distance on the locating piece 3, the roll adjustment device includes second screw rod 10, first passageway 31 that is linked together with the outside is seted up to locating piece 3, second screw rod 10 is rotatable to be located on the locating piece 3 and second screw rod 10 wear to locate in the first passageway 31, go up 4 one ends of supporting rod and wear to locate in the first passageway 31 and second screw rod 10 and last supporting rod 4 meshing transmission. The distance between supporting rod 4 and the lower supporting rod 8 can be adjusted to the roll adjustment device, not only can make the product stack the centre gripping simultaneously, then cuts, but also can fix a position the product that can correspond different thickness, has improved the efficiency of cutting greatly.
In order to prevent the clamping rods from damaging the product during clamping, rubber blocks 9 are respectively and fixedly arranged on the upper clamping rod 4 and the lower clamping rod 8.
In order to match products with different sizes, the lower clamping rod 8 is fixedly arranged on the positioning block 3 through threaded connection, the upper clamping rod 4 comprises a connecting rod 41 and a clamping rod body 42, the clamping rod body 42 is connected with the connecting rod 41 through threads, and the other end of the connecting rod 41 is arranged on the positioning block 3. Go up supporting rod 4 and lower supporting rod 8 dismantled and assembled setting respectively, make it can match different product sizes, and then change its length, make it have more the practicality.
