By pressing the pressing piece 66 downward, the pressing piece 66 pushes the L-shaped connecting rod 65 to move downward, and the other end of the L-shaped connecting rod 65 is connected to the trapezoidal blade plate 62. Therefore, the trapezoidal blade plate 62 will move along the through groove at the bottom of the connecting plate 2 The groove slides downward, so that the trapezoidal blade 62 cuts the rubber strip on the feeding wheel 8, and also includes a cutting groove 9, which is provided with a plurality of cutting grooves 9. The cutting grooves 9 are arranged in an equidistant circular array around the feeding wheel 8. The setting of the cutting groove 9 helps the trapezoidal blade 62 to cut the rubber strip smoothly. After the cutting is completed, the pressing piece 66 is released, and the trapezoidal blade 62 is reset under the action of the compression spring 64. A connecting block 3 is welded to the bottom of the right end of the arc-shaped handle 1, and a middle wheel 4 is arranged in a groove arranged at the center of the right end of the bottom of the connecting block 3. The center of the middle wheel 4 is rotatably installed with a third fixed shaft 11, and the front and rear ends of the third fixed shaft 11 are respectively fixedly connected to the inner side of the groove at the right end of the bottom of the connecting block 3. The diameter of the middle wheel 4 is larger than the diameter of the feeding wheel 8. The diameter of the middle wheel 4 is larger than the feeding wheel 8, so as to provide a stronger pressing effect, ensuring that the rubber strip is tightly pressed into the rubber strip groove reserved on the doors and windows. The connecting block 3 is an isosceles "trapezoidal" structure. An adjusting unit 5 is arranged at the left end of the bottom of the connecting block 3. The adjusting unit 5 comprises a bidirectional threaded rod 51, a first fixed shaft 52, a clamping piece 53, an edge wheel 54 and a button block 55. The bidirectional threaded rod 51 is arranged on the inner side of the groove arranged at the left end of the connecting block 3, and the front and rear ends of the bidirectional threaded rod 51 are respectively rotatably connected to the connecting block 3 through bearings, and the front end of the bidirectional threaded rod 51 is fixedly connected to the button block 55 arranged on the front side of the connecting block 3. The thread directions of the front and rear ends of the bidirectional threaded rod 51 are opposite, and the front and rear ends of the bidirectional threaded rod 51 are respectively threadedly installed with clamping pieces 53.The clamping member 53 is a "U"-shaped structure, and a side wheel 54 is respectively arranged at the inner bottom of the clamping member 53. The bottom of the clamping member 53 and the through hole arranged in the center of the side wheel 54 are respectively rotatably mounted on the outer side of the first fixed shaft 52 fixedly installed at the bottom of the groove at the left end of the connecting block 3. By rotating the knob block 55, it drives the bidirectional threaded rod 51 to rotate. Since the threads at the front and rear ends of the bidirectional threaded rod 51 are in opposite directions, the two clamping members 53 move in opposite directions along the first fixed shaft 52. In addition, since the inner bottom of the clamping member 53 "clamps" the side wheel 54, ” limit, therefore, the clamping member 53 will drive the side wheel 54 to move along the first fixed axis 52 during the movement, and by changing the distance between the side wheels 54, the side wheels 54 can press the two sides of the rubber strips of different widths, and the diameter of the side wheel 54 is smaller than the diameter of the middle wheel 4, and the diameter of the side wheel 54 is larger than the diameter of the feeding wheel 8, and the diameter of the side wheel 54 is smaller than the middle wheel 4. This design ensures sufficient pressing force, and the diameter of the side wheel 54 is larger than the feeding wheel 8, so that better support and guidance can be provided during the pressing process, ensuring that the rubber strip can pass smoothly.

[0021] The working principle of the utility model is as follows: when it is necessary to press the rubber strip on the door and window, first, the rubber strip to be compressed is passed over the feeding wheel 8, and the rubber strip is pulled or pushed to pass over the feeding wheel 8, thereby preparing for the subsequent cutting operation. Next, the rubber strip is pulled to the bottom of the middle wheel 4, and the rubber strip to be compressed is placed on the rubber strip groove reserved on the door and window. Then, the user holds the arc-shaped handle 1 and applies a certain pressure to the connecting block 3 to make the middle wheel 4 contact with the rubber strip. Since the diameter of the middle wheel 4 is larger than the feeding wheel 8, a stronger pressing effect can be provided to ensure that the rubber strip is tightly pressed into the rubber strip groove reserved on the door and window. Secondly, in the process of pressing the rubber strip, the user can adjust the distance between the side wheels 54 through the button block 55 as needed, and rotate the button block 55 to drive the bidirectional threaded rod 51 to rotate. Since the threads at the front and rear ends of the bidirectional threaded rod 51 are in opposite directions, the two clamping parts 53 are moved along The first fixed axis 52 moves in the opposite direction. In addition, since the inner bottom of the clamping piece 53 "clamps" the side wheel 54 to limit the position, the clamping piece 53 will drive the side wheel 54 to move along the first fixed axis 52 during the movement, and by changing the distance between the side wheels 54, the side wheels 54 can press the two sides of the rubber strips of different widths; finally, when it is necessary to cut the rubber strip, the user pushes the pressing piece 66 downward, and the pressing piece 66 slides toward the inside of the rectangular groove 61 through the guide groove, while pushing the L-shaped connecting rod 65 downward. The other end of the L-shaped connecting rod 65 is connected to the trapezoidal knife plate 62. Therefore, the trapezoidal knife plate 62 will slide downward along the through groove at the bottom of the connecting plate 2 to cut the rubber strip on the feeding wheel 8, and the cutting groove 9 on the feeding wheel 8 will help the trapezoidal knife plate 62 to cut the rubber strip smoothly. After the cutting is completed, the pressing piece 66 is released, and under the action of the compression spring 64, the trapezoidal knife plate 62 is reset.
