When cutting and positioning, one end of the wallpaper is fixed by the clip 7, a cutting frame 8 is provided on the telescopic rod 1, and a cutting knife assembly 9 is slidably provided on the cutting frame 8, and the wallpaper is cut by manually sliding the cutting knife assembly 9, and a wallpaper roll 13 is placed between the two sets of clamping disks 3.

[0026] Among them, the telescopic rod 1 includes a sleeve 10 and a sleeve rod 11, and one end of the sleeve rod 11 is slidably embedded in the interior of the sleeve 10. The sleeve 10 and the sleeve rod 11 are fixed by a tightening screw 12. After loosening the tightening screw 12, the sleeve rod 11 can slide along the axial direction of the sleeve 10 to adjust the extended length of the sleeve rod 11. After the adjustment is completed, tighten the tightening screw 12 to achieve tightening. The total length of the telescopic rod 1 is adjustable, and the length of the telescopic rod 1 can be adjusted accordingly according to the length of the wallpaper roll 13.

[0027] Among them, the wallpaper roll 13 is placed between two groups of clamping plates 3. According to the length of the wallpaper roll 13, the length of the telescopic rod 1 is adjusted accordingly, so that the two groups of clamping plates 3 are respectively tightly attached to the two ends of the wallpaper roll 13. The wallpaper roll 13 is clamped and fixed by the two groups of clamping plates 3, which is suitable for wallpaper rolls 13 of different specifications and sizes.

[0028] Among them, the cutting knife assembly 9 includes a slide seat 14 and a slide rod 15, and the slide rod 15 slides through the slide seat 14, a pressure plate 16 is provided at one end of the slide rod 15, and a cutting blade 18 is provided at the other end of the slide rod 15. Blades are provided on both sides of the cutting blade 18. A first spring 17 is provided between the slide seat 14 and the pressure plate 16. When the pressure plate 16 is manually pressed, the slide rod 15 is driven to slide along the slide seat 14, driving the cutting blade 18 to move down to the cutting position.

[0029] Among them, a slide groove 19 is opened on the cutting frame 8, and the slide groove 19 is slidably connected with the slide seat 14. The cutting frame 8 plays a guiding role. When cutting, the cutting knife assembly 9 slides straight along the slide groove 19 of the cutting frame 8 to limit the cutting direction, avoid the phenomenon of tilting the cutting edge, and improve the wallpaper cutting quality and cutting efficiency.

[0030] When the wallpaper is stretched to the limit of 2, the clamping plate 3 drives the wallpaper roll 13 to rotate relative to the vertical plate 2 to lengthen the wallpaper, and the unfolded wallpaper is measured by the scale on the metal ruler 5. When the unfolded length of the wallpaper reaches the specified value, the pulling of the metal ruler 5 stops, the pulling force disappears, the extrusion force of the limiting mechanism 6 is greater than the elastic force of the spring, and the pressure plate 21 of the limiting mechanism 6 presses the metal ruler 5 to limit and lock the metal ruler 5. At this time, the pressure plate 16 of the cutting knife assembly 9 is manually pressed to drive the cutting blade 18 to move downward, and the cutting knife assembly 9 is slid along the slide groove 19 to perform a straight line cutting of the wallpaper by the cutting blade 18.

[0031] Among them, the limiting mechanism 6 includes a base plate 20 and a pressure plate 21, a second spring 22 is arranged between the pressure plate 21 and the base plate 20, and the base plate 20 is fixedly connected to the tape measure base 4, the second spring 22 has a certain elastic force, under the action of the elastic force, the pressure plate 21 has a certain extrusion force, and the elastic force of the second spring 22 is greater than the elastic force of the spring inside the tape measure base 4. When the pulling force applied to the metal tape 5 disappears, the limiting mechanism 6 relies on the elastic force of the second spring 22 to lock the metal tape 5.

[0032] Among them, the metal ruler tape 5 is wound on the clockwork spring. When the metal ruler tape 5 and the clip 7 need to be reset after cutting is completed, a certain external force is applied to the pressure plate 21 to lift the pressure plate 21, and the extrusion force acting on the metal ruler tape 5 disappears. At this time, under the action of the rebound force of the clockwork spring, the metal ruler tape 5 and the clip 7 are driven to reset, which is beneficial to the next cutting positioning.

[0033] The metal ruler tape 5 is provided with scales, and the unfolded length of the wallpaper is measured by the scales. The wallpaper is unfolded smoothly, and the size of the wallpaper is measured accurately, thereby improving the cutting quality.

[0034] The clamping disc 3 is rotatably connected to the vertical plate 2 via a rotating shaft 23. When the wallpaper is unfolded, the clamping disc 3 drives the wallpaper roll 13 to rotate relative to the vertical plate 2, thereby lengthening the wallpaper.

[0035] Working principle: when in use, place the wallpaper roll 13 between the two sets of clamping plates 3, and adjust the length of the telescopic rod 1 accordingly according to the length of the wallpaper roll 13, so that the two sets of clamping plates 3 are respectively in close contact with the two ends of the wallpaper roll 13, and the wallpaper roll 13 is clamped and fixed by the two sets of clamping plates 3, and the two sets of clips 7 are respectively clamped at the edges of the wallpaper, and the metal ruler tape 5 is manually pulled, and the pulling force is greater than the elastic force of the spring and the extrusion force of the limit mechanism 6, the metal ruler tape 5 is pulled out, and the metal ruler tape 5 drives the clip 7, and the clip 7 drives the edge of the wallpaper to unfold the wallpaper, and at the same time the clamping plate 3 drives the wallpaper roll 13 to rotate relative to the vertical plate 2 to lengthen the wallpaper, and the unfolded wallpaper is measured by the scale on the metal ruler tape 5. When the wallpaper is unfolded When the opening length reaches the specified value, stop pulling the metal tape 5, the pulling force disappears, the extrusion force of the limit mechanism 6 is greater than the elastic force of the spring, and the pressure plate 21 of the limit mechanism 6 presses the metal tape 5 to limit and lock the metal tape 5. At this time, manually press the pressure plate 16 of the cutting knife assembly 9 to drive the cutting blade 18 to move down, and slide the cutting knife assembly 9 along the slide groove 19 at the same time. The wallpaper is cut in a straight line by the cutting blade 18. After the cutting is completed, the cut wallpaper can be removed. A certain external force is applied to the pressure plate 21 to lift the pressure plate 21. The extrusion force acting on the metal tape 5 disappears. At this time, under the action of the rebound force of the spring, the metal tape 5 and the clip 7 are driven to reset, which is conducive to the next cutting positioning. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model.
