Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0027] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0028] In this embodiment, the orientation of the straightening frame placed in a horizontal position is used as the reference orientation.

[0029] like Figure 1 As shown, a handheld building plastering wire mesh straightening device includes a straightening frame 10. The straightening frame 10 is provided with a roller 20 for placing the wire mesh roll, at least one set of straightening rollers for straightening the wire mesh, and two oppositely arranged cutting blades 30 for cutting the wire mesh along the straightening direction. The roller 20 has an opening 21 for pulling out the wire mesh. In this embodiment, the roller 20 is a hollow cylinder. One end of the roller 20 has an inlet for putting in the wire mesh roll. The straightening frame 10 is provided with slots corresponding to the two ends of the roller 20. The two ends of the roller 20 are connected to the two slots one by one by quick-release pins.

[0030] The straightening roller assembly includes an active roller 41 and a passive roller 42. Both the active roller 41 and the passive roller 42 are rotatably connected to the straightening frame 10. One end of the active roller 41 is fixedly connected to or integrally connected to a rotating wheel 43. A straightening gap is formed between the active roller 41 and the passive roller 42, through which the wire mesh passes.

[0031] In this embodiment, the straightening frame 10 is provided with three sets of straightening rollers; the inner wall of the straightening frame 10 is provided with at least one set of oppositely arranged connecting parts, and each connecting part is provided with at least three connecting holes 11. The two ends of the passive roller 42 are respectively rotatably connected to two oppositely arranged connecting holes 11. The distance between each set of connecting holes 11 on the same side and the corresponding active roller 41 is different. By setting connecting holes 11 at different distances from the active roller 41 to connect the passive roller 42, the distance between the passive roller 42 and the active roller 41 is different, that is, the gap size of the straightening gap is different, so as to be suitable for wire mesh of different thicknesses; each passive roller 42 has a connecting shaft at both ends, and the two connecting shafts are respectively rotatably connected to two opposite connecting holes 11, so that the passive roller 42 can rotate during the straightening process.

[0032] In this embodiment, the rotating wheels 43 connected to each active roller 41 are located on the same side of the straightening frame 10, and the three rotating wheels 43 mesh with each other in sequence. A rotating handle 44 is fixed or integrally connected to the rotating wheel 43 in the middle. The rotating handle 44 drives the rotating wheel 43 to rotate, thereby driving the active roller 41 to rotate.

[0033] A handle 50 is provided at the end of the straightening frame 10 away from the cutting blade 30. The handle 50 is a cylindrical body with a hollow interior to reduce weight and facilitate the use of the straightening device.

[0034] The straightening device also includes a cutting lever 61 and a connecting rope 62. The cutting lever 61 is disposed between the handle 50 and the straightening frame 10. One end of the connecting rope 62 is connected to the cutting lever 61, and the other end of the connecting rope 62 is connected to the cutting blade 30. In this embodiment, the cutting lever 61 is slidably connected between the handle 50 and the straightening frame 10. Multiple guide posts 63 are provided on both sides of the straightening frame 10. The connecting rope 62 abuts against the guide posts 63. The two cutting blades 30 are arranged vertically. A connecting rope 62 is connected to each end of the two cutting blades 30. The connecting rope 62 connected to the upper cutting blade 30 is arranged downward through the guide post 63, and the connecting rope 62 connected to the lower cutting blade 30 is arranged upward through the guide post 63. Each connecting rope 62 is connected to the two ends of the cutting lever 61 respectively. By pulling the cutting lever 61, the two cutting blades 30 arranged vertically move closer to each other, cutting the wire mesh, which has a scissor-like effect.

[0035] In a preferred embodiment, the handle 50 is provided with two first elastic elements 64. One end of each of the two first elastic elements 64 is fixed to one end of the handle 50, and the other end of each of the two first elastic elements 64 is fixed to one end of the cutting lever 61. The two ends of the first elastic elements 64 are located on the same side of the straightening frame 10. By providing the first elastic elements 64, the cutting lever 61 can automatically reset. Each cutting blade 30 is provided with a second elastic element 65 at both ends. One end of the second elastic element 65 is fixedly connected to the straightening frame 10, and the other end of the second elastic element 65 is fixedly connected to the corresponding cutting blade 30. By providing the second elastic elements 65, the cutting blade 30 can automatically reset after cutting.

[0036] As a preferred embodiment, the straightening frame 10 is provided with a protective cover 12 at one end where the cutting blade 30 is located. The protective cover 12 is gradually inclined downward from the top to the bottom. The upper end of the protective cover 12 can be fixed or integrally connected to the straightening frame 10. By providing the protective cover 12, workers are prevented from entering and cutting their fingers when cutting the wire mesh.

[0037] As a preferred embodiment, the surface of the passive roller 41 and / or the surface of the active roller 42 are covered with anti-slip rubber to increase the friction between the passive roller 41 and / or the active roller 42 and the wire mesh, thereby ensuring the straightening effect.

[0038] In summary, this application straightens the wire mesh by setting up a roller 20 to hold the wire mesh roll, forming a straightening gap between the active roller 41 and the passive roller 42, and setting up a cutting blade 30 to cut the wire mesh. The operation is simple and effectively improves the efficiency of straightening the wire mesh. By using two rollers to straighten the wire mesh, it is ensured that all corners of the wire mesh are in contact with the rollers and are straightened, which effectively improves the straightening quality.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
