DETAILED DESCRIPTION
[0016] For the convenience of description, if the words of "upper", "lower", "left" and "right" appear in the utility model, they only represent the same direction as the upper, lower, left and right directions of the drawing itself, and do not limit the structure, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.
[0017] It should be pointed out that the following detailed description is exemplary and is intended to provide further description of the utility model. Unless otherwise specified, all technical and scientific terms used in the utility model have the same meaning as that generally understood by ordinary technical personnel in the technical field to which the utility model belongs. The cement mortar insulation board auxiliary cutting tool of the utility model will be further described in conjunction with the drawings and specific embodiments of the description.
[0018] Reference Figure 1 And Figure 2 , an example of a cement mortar insulation board auxiliary cutting tool, comprising: a first slide rod 1, a second slide rod 2, a first limiting plate 3, a supporting block 4, a screw rod 5, a guiding groove plate 6 and a ruler 7. Specifically, the left end of the second slide rod 2 is slidably inserted into the lumen of the right end of the first slide rod 1, thereby forming an extension rod structure. The second slide rod 2 can be a solid rod body or a hollow pipe body. The supporting block 4 is two blocks, which are fixed on the upper surfaces of the first slide rod 1 and the second slide rod 2 respectively, and has a screw hole on the supporting block 4. The screw rod 5 is arranged in parallel with the extension rod structure, and one end of the screw rod 5 passes through the screw holes of the two supporting blocks 4 in turn. The threads on the two sides of the middle of the screw rod 5 are opposite in rotation direction (i.e. left-handed and right-handed threads), so that the threads between the screw holes of the two supporting blocks 4 and the screw rod 5 are opposite in rotation direction. By rotating the screw rod 5, the two supporting blocks 4 are synchronously moved closer or farther away, realizing the extension and retraction of the extension rod structure. Thus, it is suitable for insulation boards of different widths, and improves the application range of the auxiliary cutting tool.
[0019] The telescopic rod structure is horizontally arranged, and the left end of the first sliding rod 1 and the right end of the second sliding rod 2 are both fixed with the vertically arranged first limiting plate 3, so as to clamp the telescopic rod structure on the two side surfaces of the heat insulation board 8 to be cut, preventing movement during cutting and causing the auxiliary cutting function to fail. The left end of the first sliding rod 1 is fixed with the guide groove plate 6 on the upper surface, and the guide groove plate 6 is in an inverted "U" shape. The scale 7 is slidably arranged through the guide groove plate 6, and the scale 7 is perpendicular to the first sliding rod 1. It should be understood that the guide groove plate 6 and the scale 7 can also be arranged on the upper surface of the right end of the second sliding rod 2, or both the first sliding rod 1 and the second sliding rod 2 are provided with the guide groove plate 6 and the scale 7, so as to simultaneously measure the length of the heat insulation board to be cut from both ends.
[0020] In use, referring to Figure 2 , the scale 7 is pulled out to the length of the heat insulation board to be cut, and then the auxiliary cutting tool of the embodiment is placed on the upper surface of the heat insulation board 8 to be cut, and the 0 scale line at the right end of the scale 7 is aligned with the right end surface of the heat insulation board 8 to be cut. Then rotate the rotating screw 5 to make the two supporting blocks 4 approach synchronously until the first limiting plate 3 is clamped on the two side surfaces of the heat insulation board 8 to be cut, that is, the fixing of the auxiliary cutting tool is realized. Then remove the scale 7, and the worker holds the electric grinding wheel / blade to cut the heat insulation board along the first sliding rod 1 and the second sliding rod 2. During the process, the telescopic rod structure effectively prevents the grinding wheel / blade from deviating and causing the size of the obtained heat insulation board to be inconsistent with the actual needs. After cutting, reverse rotation of the rotating screw 5 makes the two supporting blocks 4 move away synchronously, and then the auxiliary cutting tool is removed from the heat insulation board.
[0021] In another embodiment, referring to Figure 3 , the first sliding rod 1 and the second sliding rod 2 of the cement mortar heat insulation board auxiliary cutting tool of the above embodiment are both square tubes, and the front wall surface of the first sliding rod 1 is open, and the front wall surfaces of the first sliding rod 1 and the second sliding rod 2 are flush after the second sliding rod 2 is inserted into the lumen of the first sliding rod 1. Thus, the cutting surface obtained by the electric grinding wheel / blade cutting the heat insulation board along the first sliding rod 1 and the second sliding rod 2 remains flush.
[0022] In another embodiment, referring to Figure 1 and Figure 2 , the cement mortar heat insulation board auxiliary cutting tool of the above embodiment further comprises a vertically arranged positioning bolt 9 which is threadedly connected in the upper surface screw hole of the guide groove plate 6, so as to temporarily fasten the scale 7 after pulling out the length of the heat insulation board to be cut, and prevent the position of the scale 7 from changing during movement.
[0023] In another embodiment, referring to Figure 1 and Figure 2 , the outer end of the scale 7 of the cement mortar insulation board auxiliary cutting tool of the above-mentioned embodiment is provided with a second limiting plate 10 arranged vertically downward. In use, the second limiting plate 10 is attached to the side wall surface of the insulation board 8 to be cut, so that the 0 scale line at the right end of the scale 7 is automatically aligned with the right end surface of the insulation board 8 to be cut, which is more accurate and helps to improve work efficiency.
[0024] In another embodiment, referring to Figure 1 and Figure 2 , at least one end of the lead screw 5 of the cement mortar insulation board auxiliary cutting tool of the above-mentioned embodiment is fixed with a hand wheel 11, so as to drive the lead screw 5 to rotate more quickly.
[0025] The above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
