the first shearing fork group comprises two first shearing fork arms, and one end of each first shearing fork arm is rotatably arranged on the first rack;

the second shearing fork group comprises two second shearing fork arms which are arranged in a crossing way, and a second through hole is formed at the crossing point of each second shearing fork arm; one end of each second shearing arm is respectively connected with the other end of each first shearing arm in a rotating way, and the fixing piece further comprises a first bolt which is arranged in the second through hole in a penetrating way, so that the second shearing arms swing around the first bolts for increasing the range.

5. A refuse bag necking machine in accordance with claim 4, wherein said scissors hinge further comprises:

the third shearing fork group comprises two third shearing fork arms and second bolts which are arranged in a crossing way, and a third through hole is formed at the crossing point of each third shearing fork arm; one end of each third shearing fork arm is respectively connected with the other end of each second shearing fork arm in a rotating way, and the second bolt penetrates through the third through hole;

the fourth shearing fork group comprises two fourth shearing fork arms and third bolts which are arranged in a crossing way, and a fourth strip-shaped through hole is formed at the crossing point of each fourth shearing fork arm; one end of each fourth shearing fork arm is respectively connected with the other end of each third shearing fork arm in a rotating way, and the third bolt penetrates through the fourth strip-shaped through hole.

6. The garbage bag necking machine core according to claim 1, wherein the first guide plate and the second guide plate are of double-layer structures, the first guide plate comprises an upper clamping plate and a lower clamping plate, the second guide plate is provided with an upper clamping plate guide groove and a lower clamping plate guide groove which are respectively matched with the upper clamping plate and the lower clamping plate, the upper clamping plate is in sliding connection with the upper clamping plate guide groove so as to achieve upper portion shrinkage of a garbage bag opening, and the lower clamping plate is in sliding connection with the lower clamping plate guide groove so as to achieve lower portion shrinkage of the garbage bag opening.

7. The garbage bag necking machine core of claim 6, wherein positioning holes are formed in two sides of the first guide plate and the second guide plate, guide shafts are accommodated in the positioning holes, the guide shafts are arranged on the first spring groups close to one ends of the first guide plates, in an initial state, the scissor hinge groups and the power assembly are in a tightening state, the first guide plates compress the first spring groups, when the power assembly drives the scissor hinge assemblies to extend out, the first guide plates tightly push the first guide plates under the action of elasticity of the first spring groups, so that movement generated by gaps between the scissor hinge assemblies is eliminated, and the scissor hinge assemblies are in a stable state when running.

8. A refuse bag necking machine core according to claim 7, characterized in that the second spring group is arranged at one end of the guide shaft close to the second guide plate, when the first guide plate is contacted with the second guide plate, the second guide plate compresses the second spring group to buffer the acting force between the heat sealing assemblies, after the heat sealing is finished, the power assembly drives the scissor hinge assemblies to retract, and the second spring group pushes the second guide plate tightly to assist discharging.

9. A packaged toilet seat, comprising:

the toilet seat body comprises a garbage bag storage opening at the top and a discharge plate far away from the garbage bag storage opening;

the bag fixing assembly is arranged at the garbage bag storage opening and used for storing hollow garbage bags;

the bag feeding assembly is arranged below the bag fixing assembly;

and the refuse bag necking machine core provided below the bag feeding assembly and comprising any one of the refuse bag necking machine cores in claims 1-8.

10. The packaged toilet seat according to claim 9, wherein the bag securing assembly comprises:

the hollow column is used for sleeving a hollow garbage bag;

a chassis extending horizontally outwards from the bottom end of the hollow column body, and the chassis is fixed on the toilet seat body;

the annular cover body is buckled at the top end of the hollow cylinder;

one end of the garbage bag bypasses the annular cover body from the outer side of the hollow cylinder to enter the inner side of the hollow cylinder.
