DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 to Figure 7 As shown, an efficient and easy-to-use sticky paper roll comprises a roll 1 and sticky paper 2 wound thereon, the roll 1 is rotatably arranged on a roll frame 3, a punching mechanism 4 and a handle 5 are arranged on the roll frame 3, a rotation locking mechanism 6 is arranged between the handle 5 and the roll 1, wherein the punching mechanism 4 is provided for the purpose of making a row of dot matrix perforations on the sticky paper 2, so as to facilitate direct tearing by hand without the aid of scissors and other tools, and the rotation locking mechanism 6 is provided for the purpose of locking the roll 1 when the paper roll is not in use, preventing the roll 1 from rotating freely and causing the sticky paper 2 to fall off, thereby avoiding waste of materials.

[0028] Specifically, the punching mechanism 4 includes a transition roller 4a and a punching knife 4b, the transition roller 4a is located above the reel 1 and the rotation center axes of the two are parallel, and the distance between the punching knife 4b and the transition roller 4a is variable; the punching knife 4b is in the form of a flat sheet, and its two sides are inserted into the slide groove provided on the reel frame 3. The cutting edge of the side close to the transition roller 4a is provided with saw teeth, and the side away from the transition roller 4a is provided with a push block 4c, the slide groove is located in the bracket provided on the reel frame 3, and a compression spring 4d is provided between the push block 4c and the bracket. The push block 4c is closer to the handle 5 than the saw teeth. By pushing the push block 4c in the direction of the transition roller 4a, the saw teeth can be moved to contact the transition roller 4a, and the sticky paper 2 between the two can be pressed to cut a row of dot matrix perforations, so that the sticky paper 2 at the perforation can be torn off by hand, which is convenient for construction and use. The function of the compression spring 4d is to reset the punching knife 4b away from the transition roller 4a, and the sticky paper 2 can be released normally.

[0029] On the other hand, specifically, the rotation locking mechanism 6 includes a locking block 6a arranged beside the rotating shaft of the reel 1 and an operating plate 6b arranged beside the handle 5, a rod 1 6c and a rod 2 6d are arranged between the locking block 6a and the operating plate 6b, one end of the rod 1 6c and the rod 2 6d are in contact and the middle of both are hinged to the reel frame 3; the end of the rod 1 6c away from the rod 2 6d is connected to the locking block 6a, and the end of the rod 2 6d away from the rod 1 6c is connected to the operating plate 6b, a section of the rod 1 6c close to the rod 2 6d is in an arc shape, a tension spring 6e is arranged between the section of the rod 1 6c close to the locking block 6a and the reel frame 3, the operating plate 6b is an arc panel that fits the shape of the outer surface of the handle 5, and a variable acute angle is formed between the operating plate 6b and the handle 5, and the rotating shaft of the reel 1 is close to the locking block 6 One side of a is provided with concave or convex patterns, and the side of the locking block 6a close to the reel 1 is provided with corresponding convex patterns or concave patterns, and the convex patterns are embedded in the concave patterns to be stuck with each other. When using an efficient and easy-to-use sticky paper roll of the utility model, the hand holds the operating plate 6b and the grip 5, and the angle between the two is reduced. Due to the rotation at the hinge fulcrum, the rod 2 6d squeezes the arc-shaped segment of the rod 1 6c, and the rod 1 6c drives the locking block 6a away from the rotating shaft of the reel 1. At this time, the locking block 6a cannot limit the rotation of the reel 1. Similarly, if the efficient and easy-to-use sticky paper roll of the utility model is not used, the operating plate 6b is released, and under the action of the tension spring 6e, the locking block 6a will contact the end face of the rotating shaft of the reel 1, and the convex and concave patterns are used to lock the reel 1, thereby preventing the reel 1 from rotating freely.

[0030] In addition, a telescopic support leg 3a is provided at the lower part of the roll frame 3, which is inclined downward and can keep the surface of the sticky paper 2 from contacting the surface of the object below when placed to avoid pollution and waste.

[0031] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, changes, modifications or additions are all covered within the protection scope of the present invention.
