[0019] Embodiments

[0020] Please refer to Figures 1-2 The utility model provides a kind of gypsum board segmentation auxiliary tool, including two end rotationally connected first calipers 1 and second calipers 2, first calipers 1 and second calipers 2 all have scale 100, first cutter assembly 3 is slidably installed on first calipers 1, first cutter assembly 3 can slide along first calipers 1, second cutter assembly 4 is slidably installed on second calipers 2, second cutter assembly 4 can slide along second calipers 2, the included angle of the sliding direction of first cutter assembly 3 and the sliding direction of second cutter assembly 4 can be changed arbitrarily;When using, generally, second calipers 2 is relative to first calipers 1 overturn, so that first calipers 1 and second calipers 2 are perpendicular, the zero scale 100 of first calipers 1 is aligned with the starting point of gypsum board mountain, and first cutter assembly 3 is slid to the zero scale 100 end of first calipers 1, press first calipers 1, and slide first cutter assembly 3 to cut gypsum board, the scale 100 on second calipers 2 can cooperate with first calipers 1 to measure the interval of first calipers 1 from the edge of gypsum board, to facilitate measurement;The position of second calipers 2 on gypsum board can also be fixedly limited, so as to rotate first calipers 1, and cut the arc shape of gypsum board.

[0021] In specific embodiments, reference is made to Figure 1 , Figure 2The first cutter assembly 3 comprises a first sliding block 31 and a cutter 32. The first sliding block 31 slides along the first ruler 1. The first sliding block 31 is longitudinally provided with a column groove 311. The cutter 32 penetrates from the bottom of the first sliding block 31 to the inside of the column groove 311 and is connected with a pressing piece 33 arranged above the first sliding block 31. An elastic piece 34 is arranged in the column groove 311. The two ends of the elastic piece 34 abut against the pressing piece 33 and the bottom of the column groove 311 respectively. The part of the cutter 32 below the first sliding block 31 is connected with a limiting piece 35. In the scheme, the position of the first sliding block 31 on the first ruler 1 can be changed by manually sliding the first sliding block 31. In use, the pressing piece 33 needs to be pressed so that the pressing piece 33 can overcome the elastic force of the elastic piece 34 and the tip of the cutter 32 exceeds the lower surface of the first ruler 1 and penetrates into the gypsum board. At this time, the first sliding block 31 is slid to cut the gypsum board. When the cutting is completed, the pressing piece 33 is released. The elastic piece 34 pushes the cutter 32 so that the tip of the cutter 32 is higher than the lower surface of the first ruler 1, thereby avoiding scratching the gypsum board.

[0022] In specific embodiments, referring to Figure 1 、 Figure 2 The first ruler 1 is provided with a first long groove 11 in the middle. The cutter 32 is arranged in the middle of the first sliding block 31 and moves in the first long groove 11. In the scheme, since the first ruler 1 has a width, the width will affect the cutting precision of the cutter 32. The first long groove 11 can facilitate the observation of the position of the tip of the cutter 32. When the cutter 32 slides to the leftmost end of the first ruler 1, the cutter 32 can be flush with the end point scale 100 on the first ruler 1. Further, the end of the first ruler 1 close to the rotationally connected end of the second ruler 2 is further provided with a scale 100 that can be spliced with the scale 100 of the second ruler 2. The influence of the width of the first ruler 1 can be overcome, and the precision of the position of the cutter 32 can be improved.

[0023] In specific embodiments, referring to Figure 1 、 Figure 2 The second cutter assembly 4 comprises a U-shaped piece 41 and a nail body 42. The second ruler 2 is provided with a second long groove 21 in the middle. The U-shaped piece 41 is inserted from the side of the second ruler 2 towards the second long groove 21. The nail body 42 penetrates from above the U-shaped piece 41 into the second long groove 21 and extends to the bottom of the second ruler 2. The U-shaped piece 41 is fixed on the second ruler 2 by penetrating bolts. In the scheme, one end of the second ruler 2 can rotate relative to the first ruler 1. After rotation, the second ruler 2 can overlap the first ruler 1 by a part to reduce the width of the whole device and facilitate storage. Before the second ruler 2 is rotated, the first cutter assembly 3 needs to be slid to the rightmost end of the first ruler 1. The length of the second ruler 2 in the application is less than that of the first ruler 1.

[0024] In specific embodiments, referring to Figure 1 、 Figure 2The two sides of the first sliding block 31 are provided with C-shaped handle pieces 312; in this scheme, the handle pieces 312 on the two sides of the first sliding block 31 can facilitate the fingers of the personnel to provide a pushing force for the first sliding block 31, and facilitate the operation and use of the personnel.

[0025] In specific embodiments, referring to Figure 1 , Figure 2 The two sides of the first caliper 1 are provided with guide grooves 12, and the inner side wall of the first sliding block 31 is provided with clamping blocks 313 matched with the guide grooves 12; in this scheme, the first sliding block 31 can be clamped under the action of the clamping blocks 313 and the guide grooves 12, so as to avoid the first sliding block 31 from being separated from the first caliper 1, and to provide a guiding effect.

[0026] In specific embodiments, referring to Figure 1 , Figure 2 The sliding range of the cutter 32 on the first caliper 1 is the same as the range of the scale 100 on the first caliper 1; in this scheme, the moving range of the cutter 32 on the first caliper 1 can be known through the scale 100 on the first caliper 1, and the moving distance of the cutter 32 can be conveniently observed.

[0027] In specific embodiments, referring to Figure 1 , Figure 2 Figure 1 Figure 2 The sliding interval of the nail body 42 on the second caliper 2 is the same as the range of the scale 100 on the second caliper 2; in this scheme, the scale 100 on the second caliper 2 is used to measure the distance of the first caliper 1 from the edge of the gypsum board, and can cooperate with the first caliper 1 to realize the measurement of length and width, thereby improving the convenience of gypsum board cutting measurement.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
