[0003] For example, the publication number is CN104708644A, and the name is a cutting tool. Cutting is performed by setting scissor blades. However, when cutting with the scissor blades, the residual asphalt material of the waterproof roll will remain on the blades, causing the scissor blades to get stuck during cutting, making it difficult to operate, and reducing the cutting efficiency of the cutting tool.

[0004] Therefore, it is necessary to design a waterproof coil cutting tool to improve the above problems. Utility Model Content

[0012] Furthermore, the two bent ends of the bent baffle are arc-shaped, and the centers of the arcs coincide with the geometric center of the cutting portion.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model provides a cutting device and a pressing device. The pressing device presses two sets of circular blades of the cutting device to cut the waterproofing roll. When cutting, the asphalt material on the waterproofing roll moves along the tangent direction, so that the asphalt material on the waterproofing roll will not remain. At the same time, the two sets of circular blades will not get stuck, thereby improving the cutting efficiency of the cutting tool;

[0015] (2) A bending baffle is provided above the two sets of circular blades to prevent the asphalt on the waterproof membrane from splashing everywhere. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution, design method and advantages of the utility model clearer, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1-Figure 3 As shown, the utility model provides a waterproof coiled material cutting tool, including a cutting device and an extrusion device 1, wherein the cutting device includes two staggered cutting parts, the outer side of the cutting part is provided with a cutting edge, the extrusion device 1 is arranged above the two cutting parts, the two cutting parts are connected by the extrusion device 1, and the extrusion device 1 is operated so that the cutting edges of the two cutting parts are tangent to form a cutting area for cutting the waterproof coiled material;

[0023] Further, the cutting portion is a circular blade 4, and the outer edge of the circular blade 4 is a cutting edge;

[0024] Further, the extrusion device 1 includes a transverse connecting rod 3 and an elastic element, the transverse connecting rod 3 is sleeved with two vertical connecting rods 2, the two vertical connecting rods 2 are slidably connected to the transverse connecting rod 3, and the tops of the two vertical connecting rods 2 are connected by the elastic element;

[0025] The bottoms of the two vertical connecting rods 2 are connected to the cutting portion;

[0026] Further, the elastic element is a helical spring or an arc-shaped spring structure;

[0027] Furthermore, the two vertical connecting rods 2 are also connected with a bending baffle 5, which is a concave plate with two ends bent, and the bent end of the bending baffle 5 is located close to the circular blade 4;

[0028] Among them, the concave plate is provided with two long through holes arranged horizontally and in parallel, and the two vertical connecting rods 2 respectively pass through the two long through holes on the concave plate to respectively install the two circular blades 4 on both sides of the bottom of the concave plate; a cylinder is connected to one side of the bottom of the vertical connecting rod 2, and a mounting hole is provided at the center of one end face of the circular blade 4, and the cylinder at the bottom of the vertical connecting rod 2 cooperates with the mounting hole to connect the bottom of the vertical connecting rod 2 with one end face of the circular blade 4;

[0029] Furthermore, the two bent ends of the bent baffle 5 are arc-shaped, and the centers of the arcs coincide with the geometric center of the cutting portion;

[0030] It is worth mentioning that the utility model sets a cutting device and an extrusion device 1 to remove the asphalt material residue on the waterproof roll material so that the two groups of circular blades 4 will not get stuck. The cutting device includes two circular structure cutting parts with external cutting arrangement, and the cutting part is a circular blade 4. The two circular blades 4 are connected by an elastic element. When in use, the operator squeezes the two groups of circular blades 4 together through the extrusion device 1 to perform the cutting operation. After the cutting is completed, the extrusion device is released, and the blades will automatically return to the initial position and be ready for the next cutting. The cutting edges of the two groups of circular blades 4 are externally cut to form a cutting area to cut the waterproof roll material.
