[0009] The cutting assembly includes a threaded rod and a sliding rod rotatably mounted on both sides of the mounting base, and a slider is mounted on both the threaded rod and the sliding rod, wherein the slider located on the threaded rod is threadedly connected to the threaded rod.

[0010] An auxiliary pressure assembly is disposed inside the mounting base.

[0011] The auxiliary pressure assembly includes two pairs of elastic telescopic rods fixedly installed inside the mounting base. The telescopic end of each elastic telescopic rod slides through the side wall of the mounting base, and a U-shaped mounting plate is fixedly installed on the telescopic end of each pair of elastic telescopic rods.

[0012] Preferably, a screw cap is fixedly installed at the end of the threaded rod, and a cutting tooth and a support cylinder are fixedly installed together between the pair of sliders.

[0013] Preferably, a support cylinder is slidably mounted on the end of the mounting base, and mounting grooves are provided on both sides of the support cylinder. A protrusion is slidably mounted inside the mounting groove, and a spring is installed between the protrusion and the inner sidewall of the mounting groove. Insertion holes are provided on both sides of the mounting base, and the protrusion and the insertion hole are slidably engaged.

[0014] Preferably, a rotating sleeve is slidably mounted on the support cylinder, and limit plates are slidably mounted on both sides of the support cylinder near the two ends of the rotating sleeve.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] Firstly, this utility model uses a rubber suction cup to stably attach the device to a workbench, making it convenient for users to use without the need for carrying it by hand. In addition, the cutting teeth facilitate the cutting of the stretch film, avoiding uneven tears. The support cylinder effectively supports the stretch film, preventing the cut from sticking to the film body after tearing, thus affecting future use.

[0018] Secondly, the auxiliary pressure component of this invention can effectively apply pressure to the stretch film, ensuring that the stretch film can rotate stably during use, thereby avoiding unstable rotation when the stretch film is pulled, which would affect the normal use of the stretch film.

[0019] This technology addresses the problem that while existing technologies facilitate the use of stretch film, the manual handling required for frequent use can lead to fatigue and wobbling, resulting in unstable film placement and affecting the overall performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] This utility model provides an improved PE stretch film. The technical solution of this utility model is as follows:

[0029] like Figures 1-4 As shown, a PE stretch film includes a mounting base 1, with multiple columns 2 fixedly mounted on the bottom of the mounting base 1, and also includes a cutting component and an auxiliary pressure component. The cutting component and auxiliary pressure component can play a good auxiliary role in use.

[0030] A cutting assembly is provided at the end of the mounting base 1.

[0031] The cutting assembly includes a threaded rod 11 and a slide rod 12 respectively rotatably mounted on both sides of the mounting base 1. A slider 13 is mounted on both the threaded rod 11 and the slide rod 12. The slider 13 located on the threaded rod 11 is threadedly connected to the threaded rod 11. By rotating the threaded rod 11 and the slide rod 12, the slider 13 can be moved, which facilitates adjustment according to the usage of the stretch film 4.

[0032] The auxiliary pressure component is located inside the mounting base 1.

[0033] The auxiliary pressure assembly includes two pairs of elastic telescopic rods 18 fixedly installed inside the mounting base 1. The telescopic end of each elastic telescopic rod 18 slides through the side wall of the mounting base 1. The telescopic ends of each pair of elastic telescopic rods 18 are fixedly installed with a U-shaped mounting plate 19. The elastic telescopic rods 18 can move the U-shaped mounting plate 19, thereby ensuring that the auxiliary pressure assembly can be used normally.

[0034] Furthermore, a screw cap 16 is fixedly installed at the end of the threaded rod 11, and a cutting tooth 14 and a support cylinder 15 are fixedly installed between a pair of sliders 13. The screw cap 16 allows the threaded rod 11 to be easily rotated, which facilitates the movement of the sliders 13, and in turn, the movement of the cutting tooth 14 and the support cylinder 15. This allows for adjustment according to the usage of the stretch film 4, ensuring that the cutting tooth 14 and the support cylinder 15 are always in the appropriate position.

[0035] Furthermore, a support cylinder 5 is slidably installed at the end of the mounting base 1. Mounting grooves 7 are provided on both sides of the support cylinder 5. A protrusion 8 is slidably installed inside the mounting groove 7. A spring 9 is installed between the protrusion 8 and the inner side wall of the mounting groove 7. Insertion holes 17 are provided on both sides of the mounting base 1. The protrusion 8 and the insertion hole 17 are slidably engaged. The spring 9 can stably insert the protrusion 8 into the insertion hole 17, thereby ensuring that the support cylinder 5 can be stably installed on the mounting base 1. When it is necessary to replace the wrapping film 4, the support cylinder 5 can be removed by pressing the protrusions 8 on both sides, thus facilitating the replacement of the wrapping film 4.

[0036] Furthermore, a rotating sleeve 6 is slidably installed on the support cylinder 5, and limit plates 10 are slidably installed on both sides of the support cylinder 5 near the two ends of the rotating sleeve 6. The limit plates 10 can limit the rotating sleeve 6 and the stretch film 4, ensuring that the stretch film 4 rotates stably and does not move left or right.

[0037] Furthermore, a stretch film 4 is fitted onto the rotating sleeve 6, and a rubber suction cup 3 is fixedly installed at the bottom of each column 2. A roller 20 is rotatably installed inside the U-shaped mounting plate 19. The rubber suction cup 3 ensures that the mounting base 1 is stably adsorbed and fixed on the workbench. The U-shaped mounting plate 19 and the roller 20 ensure that they can apply auxiliary pressure to the stretch film 4, thereby ensuring that the stretch film 4 rotates more stably.

[0038] The specific working method is as follows: the mounting base 1 is stably fixed on the workbench by the rubber suction cup 3, the stretch film 4 is sleeved on the rotating sleeve 6, and after the limit plates 10 on both sides are installed, the support cylinder 5 is slidably installed on the front end of the mounting base 1. When it moves to the designated position, under the action of the spring 9, it can move the protrusion 8 into the insertion hole 17, thereby achieving the installation effect of the stretch film 4. By rotating the screw cap 16, the threaded rod 11 is rotated, thereby moving the cutting tooth 14 and the support cylinder 15. When it is necessary to replace the stretch film 4, simply press down the protrusions 8 on both sides to remove the support cylinder 5, which is convenient for replacement. The roller 20 can provide good auxiliary pressure for the stretch film 4 to ensure that it can work normally.
