[0031] Embodiment 1

[0032] Please refer to Figures 1 - 6In the embodiment of the present invention, a packaging film bracket comprises two support frames 6, a third cross bar 3 is fixedly connected between one end of the two support frames 6, a sliding cutting device is provided on the upper side of the third cross bar 3, a second cross bar 12 is provided between the ends of the two support frames 6 facing away from the third cross bar 3, the upper ends of the two support frames 6 are fixedly connected with an insertion rod 9, and the side walls at both ends of the second cross bar 12 are provided with a vertical through-hole 16, the two insertion rods 9 are respectively inserted into the two insertion holes 16 at both ends of the second cross bar 12, and two sliding bases 11 are slidably connected to the second cross bar 12. The two sliding bases 11 are symmetrically arranged, and a clamping limit device is provided on the second cross bar 12. The first cross bar 7 is fixedly connected between the two support frames 6, and the packaging film bracket can be directly placed on the desktop for use.

[0033] It also includes two hooks 8 installed on the wall. The first cross bar 7 can hang the entire bracket on the wall by hooking with the two hooks 8. The side walls of the other two support frames 6 are provided with mounting holes 17. The two support frames 6 can also be directly fixed to the wall by passing wall nails through the mounting holes 17. The vertical rod ends of the two support frames 6 can also be provided with a telescopic structure similar to the telescopic part of a fishing rod (not shown), so that the height of the support frame 6 can be adjusted.

[0034] Specifically, the sliding cutting device includes a track rod 4, which is fixedly connected to the upper side of the third cross bar 3. A track groove 5 is opened on the upper side of the track rod 4. A slider 15 is slidably connected in the track groove 5. The upper side of the slider 15 is fixedly connected to the cutting knife 2. The upper side of the cutting knife 2 is fixedly connected to the push cap 1. The cutting knife 2 is arranged in an inverted trapezoidal shape, and the cutting edge of the cutting knife 2 is located at the inclined edges on both sides. The cross-section of the track groove 5 is arranged in a T-shape. The cross-sectional shape of the slider 15 is adapted to the cross-sectional shape of the track groove 5. When one side of the stretch film is against the track groove 5, the finger pushes the cutting knife 2 to move along the track groove 5 through the push cap 1, so that the cutting knife 2 can quickly cut the stretch film.

[0035] It should be noted that, in addition to being tubular, the third crossbar 3 may also be provided in a sheet shape (not shown). When the third crossbar 3 is in a sheet shape, an embedded cutting knife may be directly mounted on the third crossbar 3 to cut the stretch film.

[0036] Specifically, the clamping limit device includes two limit clamps 10, which are sleeved on the second cross bar 12. Bolts 14 are passed through the side walls at both ends of each limit clamp 10, and butterfly nuts 13 are threaded on the bolts 14. The two limit clamps 10 are respectively located on the opposite sides of the two sliding bases 11. When the limit clamps 10 need to be fixed on the second cross bar 12, the two limit clamps 10 can be fixedly clamped on the second cross bar 12 by screwing the butterfly nuts 13 on the bolts 14.

[0037] The working principle of this utility model is:

[0038] During use, first fix the two hooks 8 to the wall by screws, then hook the first crossbar 7 on the two hooks 8, so that the whole bracket can be hung on the wall. After that, remove the second crossbar 12, then insert the winding film tube onto the second crossbar 12, and then make the two sliding bases 11 respectively abut against both ends of the winding film, and press the two limit clips 10 on the second crossbar 12 against the back side walls of the two sliding bases 11. After that, by screwing the wing nut 13 on the bolt 14, fix the two limit clips 10 on the second crossbar 12, and the installation of the winding film tube can be completed. Finally, insert the jacks 16 at both ends of the second crossbar 12 onto the two insertion rods 9. At this time, the winding film can be pulled out for use. After the pulling is completed, one side of the winding film abuts against the track groove 5, and then the finger pushes the cutting knife 2 to move along the track groove 5 through the pushing cap 1, so that the cutting knife 2 can quickly cut the winding film.

[0039] Embodiment 2

[0040] The difference between Embodiment 2 and Embodiment 1 is that the support frame 6 is arranged in a C shape, one side of the top section of the support frame 6 is arranged to slope downward, the second crossbar 12 is located in the middle of the top section of the support frame 6, and the third crossbar 3 is located at the inclined bottom end of the top of the support frame 6, as Figure 7 shown;

[0041] Embodiment 3

[0042] The difference between Embodiment 3 and Embodiment 1 is that the support frame 6 is arranged in a C shape, one side of the top section of the support frame 6 is arranged to be vertically downward, the second crossbar 12 is located in the middle of the top section of the support frame 6, and the third crossbar 3 is located at the position of the vertically downward bottom end of the top section of the support frame 6, as Figure 8 shown.

[0043] Embodiment 4

[0044] The difference between Embodiment 4 and Embodiment 1 is that the cross-sectional shapes at both ends of the second crossbar 12 are non-circular polygons, Figure 9 and Figure 10 a quadrilateral is adopted. Grooves 18 with the same shape as the non-circular polygons at the ends of the second crossbar 12 are provided on the upper sides of the two support frames 6. The grooves 18 are arranged to penetrate from left to right (as Figure 9 shown) or recessed by half (as Figure 10 shown). The recessed-by-half setting can block both ends of the second crossbar 12 to prevent the second crossbar 12 from sliding left and right. When both ends of the second crossbar 12 are stuck in the grooves 18 of the support frame 6, the second crossbar 12 can be restricted and fixed and cannot rotate, and the second crossbar 12 can be fixed without the cooperation of the insertion rod 9 and the jack 16.

[0045] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to the illustrations in the specification and the above description; however, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
