The upper blade is mounted on the top of the right-angle plate at a rearward tilt, and the lower blade is mounted on the bottom of the right-angle plate at a rearward tilt.

[0008] In one embodiment of this utility model, the support assembly includes a limiting rod and an angle block, the right-angle plate is fixedly disposed with the handle, a support block is disposed on the back of the right-angle plate, and the limiting rod connects the support block and the angle block.

[0009] In one embodiment of the present invention, the support assembly further includes an elastic support portion and a ball bearing. The elastic support portion is installed on the front side of the corner block to support the ball bearing. The back of the right-angle plate is provided with a slot for limiting the ball bearing. The limiting rod is slidably engaged with the corner block.

[0010] In one embodiment of this utility model, the elastic support includes a rear shell, a buffer member, and a seat shell. The rear shell is disposed on the back of the corner block, the buffer member is installed inside the rear shell, and the seat shell is disposed at the front end of the buffer member to limit and support the ball bearing.

[0011] In one embodiment of this utility model, the corner block is provided with a through hole, and the buffer member moves through the through hole.

[0012] In one embodiment of this utility model, the elastic support portion and the ball bearings on one side of the corner block are arranged in multiple sets.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] Please see Figures 1-4 This utility model provides a wallpaper trimming device, including a handle 10, a support assembly 20 and a cutting assembly 30.

[0025] Holding the handle 10, the support assembly 20 and the cutting assembly 30 work together to quickly and smoothly cut off excess wallpaper at the corner.

[0026] The support assembly 20 is mounted on the front end of the handle 10. The cutting assembly 30 includes a right-angle plate 310, an upper blade 320, and a lower blade 330. The right-angle plate 310 is located on the front side of the support assembly 20, the upper blade 320 is mounted on top of the right-angle plate 310 at a rearward tilt, and the lower blade 330 is mounted on the bottom of the right-angle plate 310 at a rearward tilt. The tilt angle of the upper blade 320 and the lower blade 330 should be less than 5°.

[0027] The wallpaper has been applied to the wall. Hold the handle 10 with one hand and position the right-angle plate 310 of the cutting component 30 at the corner of the wall. Move it gradually from bottom to top or from top to bottom. As the handle 10 moves the support component 20 and the cutting component 30 upwards, the upper blade 320 and lower blade 330 of the cutting component 30 can cut off the excess wallpaper in the corner area. This allows for quick and clean cutting of small amounts of excess wallpaper in the corner area, making it faster and more precise than traditional utility knives or other ordinary knives.

[0028] In the above specific embodiment, the support assembly 20 includes a limiting rod 240 and an angle block 210. A right-angle plate 310 is fixedly mounted to the handle 10. A support block 350 is provided on the back of the right-angle plate 310. The limiting rod 240 connects the support block 350 and the angle block 210. The support assembly 20 also includes an elastic support part 220 and a ball bearing 230. The elastic support part 220 is installed on the front side of the angle block 210 to support the ball bearing 230. A slot 340 is provided on the back of the right-angle plate 310 to limit the ball bearing 230. The limiting rod 240 slides with the angle block 210.

[0029] With the cooperation of the elastic support 220 and the ball bearing 230, the elastic support 220 can support the ball bearing 230. Under the pressure of the handle 10, a part of the ball bearing 230 will protrude through the slot 340 and contact the paper that has been laid on the wall, reducing the friction when the right angle plate 310 slides with the paper on the wall, and making the right angle plate 310 move more smoothly in the corner area.

[0030] In a specific configuration, the elastic support portion 220 includes a rear housing 221, a buffer member 222, and a seat housing 223. The rear housing 221 is located on the back of the corner block 210, the buffer member 222 is installed inside the rear housing 221, and the seat housing 223 is located at the front end of the buffer member 222 to limit and support the ball bearing 230. The buffer member 222 in the elastic support portion 220 is used to elastically support the ball bearing 230 on the front side of the seat housing 223. The buffer member 222 can be a spring structure.

[0031] Furthermore, the corner block 210 is provided with a through hole, through which the buffer 222 movably passes. Multiple sets of elastic support parts 220 and ball bearings 230 are provided on one side of the corner block 210, making the right-angle plate 310 more stable when moving vertically. The corner block 210 is provided with a small hole that movably engages with the limit rod 240. The length of the corner block 210 is longer than the length of the right-angle plate 310; this design allows the corner block 210 to protect the upper blade 320 at the top and the lower blade 330 at the bottom of the right-angle plate 310, making it safer to use.

[0032] The wallpaper trimming device works as follows: The wallpaper is already applied to the wall. Holding the handle 10 with one hand, the right-angle plate 310 of the cutting component 30 is positioned at the corner of the wall, and gradually moved from bottom to top or top to bottom. As the handle 10 moves the support component 20 and the cutting component 30 upwards, the upper blade 320 and lower blade 330 of the cutting component 30 trim excess wallpaper in the corner area, allowing for quick and smooth trimming of small amounts of excess wallpaper in the corner area. This is faster and more precise than traditional utility knives or other ordinary knives.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
