The inner shell 1 and the outer shell 2 are both U-shaped. For easy assembly, the outer shell 2 can be divided into an upper half shell and a lower half shell. The U-shaped shell includes an upper arm and a lower arm, an upper cavity 3 and a lower cavity 4 are respectively arranged on the upper arm and the lower arm, an upper roller 5 and a lower roller 6 are respectively arranged in the upper cavity 3 and the lower cavity 4, the upper roller 5 is rotatably arranged on the upper bracket 7, and the lower roller 6 is rotatably arranged on the lower bracket 8, the outer ends of the upper bracket 7 and the lower bracket 8 are respectively extended out of the outer shell 2, and the upper bracket 7 and the lower bracket 8 are elastically connected to the upper arm and the lower arm through elastic members; the upper bracket 7 and the lower bracket 8 can drive the upper roller 5 and the lower roller 6 to extend into the U-shaped groove 9 of the U-shaped shell and approach each other under the action of external force, so the inner shell 1 is provided with a first avoidance hole 10 for the upper roller 5 and the lower roller 6 to extend out of the upper cavity 3 and the lower cavity 4. And the upper bracket 7 and the lower bracket 8 are reset under the action of the elastic member and drive the upper roller 5 and the lower roller 6 back to the upper cavity 3 and the lower cavity 4.

[0030] When sealing the sealing strip of the sealing bag, put the sealing strip end of the sealing bag into the U-shaped groove 9, and then press the upper bracket 7 and the lower bracket 8 by hand, so that the upper roller 5 and the lower roller 6 are close to each other in the U-shaped groove 9, and move the utility model, the upper roller 5 and the lower roller 6 roll while acting on the sealing strip to achieve sealing.

[0031] The utility model has a variable distance between the upper roller 5 and the lower roller 6, which can be applied to sealing strips of different thicknesses. The upper roller 5 and the lower roller 6 have a certain axial length, which can be applied to the sealing of sealing strips of different numbers, and has good versatility.

[0032] Generally, the upper roller 5 and the lower roller 6 are located in the upper cavity 3 and the lower cavity 4 in the absence of external force. However, they are also allowed to partially extend out of the upper cavity 3 and the lower cavity 4.

[0033] In addition, the utility model also provides a second avoidance hole on the outer shell 2 at a position corresponding to the first avoidance hole 10 on the inner shell 1.

A through hole is provided at the bottom of the second recessed hole 17. Second bosses 18 corresponding in number and position to the second recessed holes 17 are provided on the inner shell 1. Threaded holes are provided on the second bosses 18.

[0036] The outer shell 2 and the inner shell 1 are connected by screws passing through the through holes in the first recessed holes 13 and being screwed into the threaded holes of the first protruding columns 14 , and by screws passing through the through holes in the second recessed holes 17 and being screwed into the threaded holes of the second protruding columns 18 .

[0037] It should be noted that the connection position of the outer shell 2 and the inner shell 1 of the utility model adopts a stopper structure to make the two connected firmly and not easily displaced.

[0038] The U-shaped groove 9 of the present invention is located on the inner shell 1, and the inner end of the U-shaped groove 9 can play a role of abutment. Therefore, the first boss 14 and the second boss 18 are located on the outer side of the inner shell 1 and the outer shell 2. Specifically, a horizontal extension plate 30 is centrally arranged on the outer side of the inner shell 1, and the horizontal extension plate 30 and the inner shell 1 are usually an integrally formed structure, and the first boss 14 and the second boss 18 are respectively formed on the upper and lower planes of the horizontal extension plate 30.

[0040] Specifically, the elastic member is a spring 23, and the first mounting seat is a first spring seat 24. The first spring seat 24 is arranged at the bottom surface of the first main board 19 at a position corresponding to the first concave hole 13. The first spring seat 24 can be a cylinder or a column with a cross-shaped cross section. The spring 23 is sleeved outside the first spring seat 24, and one end of the spring 23 is pressed against the first main board 19, and the other end is pressed against the screw or the bottom of the first concave hole 13. As another embodiment, the first spring seat 24 of the utility model can also be a column with a blind hole, and one end of the spring 22 is arranged in the blind hole, and the other end is pressed against the screw or the bottom of the first concave hole 13.

[0041] The purpose of providing the first spring seat 24 is to prevent the spring 23 from not being well positioned, thereby affecting the resetting of the upper bracket 7 .

[0042] In addition, the elastic member described in the present invention may be a sponge, a spring, etc., in addition to the spring 23.

[0043] In order to prevent the upper bracket 7 from being separated from the outer shell 2, the utility model is provided with a limit hook 25 on the first main board 19, the upper end of the limit hook 25 is fixedly connected to the first main board 19, and the lower end passes through the through hole on the outer shell 2 and is hooked on the inner side of the outer shell 2. The elastic member drives the upper bracket 7 to reset, and the position is limited by the limit hook 25. When the limit hook 25 is hooked on the inner side of the outer shell 2, the upper bracket 7 is reset to its position and no longer moves upward.

[0044] Likewise, if Figure 3 As shown, the lower bracket 8 of the utility model includes a second main board 26, and a third side plate 27 and a fourth side plate 28 are spaced apart on the upper plane of the second main board 26, a lower roller 6 is arranged between the third side plate 27 and the fourth side plate 28, and the roller shafts at both ends of the lower roller 6 are rotatably arranged on the third side plate 27 and the fourth side plate 28.

[0045] The elastic member is a spring 23, and the second mounting seat is a second spring seat 29. The second spring seat 29 is arranged at intervals on the upper plane of the second main board 26, and the spring 21 is sleeved outside the second spring seat 29. One end of the spring 23 is pressed against the second main board 26, and the other end is pressed against the screw or the top of the second concave hole 16. As another embodiment, the second spring seat 28 of the utility model can also be a column with a blind hole, one end of the spring 23 is arranged in the blind hole, and the other end is pressed against the screw or the top of the second concave hole 17.

[0046] The second main board 26 is provided with a limit hook 25 , the lower end of which is fixedly connected to the second main board 26 , and the upper end of which passes through a through hole on the outer shell 2 and is hooked on the inner side surface of the outer shell 2 .

[0047] It can be seen from the above that the upper bracket 7 and the lower bracket 8 of the present invention have the same structure, but are arranged in mirror symmetry.

[0048] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
