Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figs. 1 to 3 The utility model provides a kind of angle identifier of cutting line free calculation, it includes: first indicating assembly 1, second indicating assembly 2, identification assembly 3, several convex baffles 4 and limiting assembly 5;Second indicating assembly 2 is rotationally connected with the end of first indicating assembly 1;Identification assembly 3 is arranged on first indicating assembly 1 and second indicating assembly 2;Several convex baffles 4 are respectively fixedly arranged on first indicating assembly 1 and second indicating assembly 2;Limiting assembly 5 is installed at the connecting place of first indicating assembly 1 and second indicating assembly 2.

[0022] It should be noted that the device is suitable for the butt joint measurement of square tubes or square rods with the same size or two sizes that are not completely the same. When the structures of the two square tubes are not completely the same, they at least need to have one equal side length, and the edge part is used as the butt joint edge part, and then the inclined butt joint operation is performed. The two square tubes are respectively placed on the inner sides of the first indicating assembly 1 and the second indicating assembly 2, and the nut is used for rotating connection to ensure that the angle and position between the two assemblies can be flexibly adjusted. During the adjustment process, the marking assembly 3 is arranged on the first indicating assembly 1 and the second indicating assembly 2, which facilitates the user to watch and mark accordingly when adjusting to the required angle and position. At the same time, a plurality of protruding baffles 4 are respectively fixed on the first indicating assembly 1 and the second indicating assembly 2, which play a positioning role for the square tubes and ensure that the correct distance and position between the tool and the cut material are maintained during the cutting process. The protruding baffles 4 are in an integral structure with the first plate body 11, the first synchronous part 12, the second plate body 21 and the second synchronous part 22, which can be obtained by bending a whole planar structure part. The limiting assembly 5 is installed at the connection between the first indicating assembly 1 and the second indicating assembly 2, which functions to realize positioning after adjusting to the appropriate position, and ensure the accuracy of the cutting line and the accuracy of the angle. Through the cooperative work of the first indicating assembly 1 and the second indicating assembly 2, the user can quickly and accurately determine the cutting line and angle without calculation, thereby improving the work efficiency.

[0023] In some examples, further, the first indicating assembly 1 comprises: a first plate body 11, a first synchronous part 12 and a first sliding block 13, the first plate body 11 is divided into a straight section and a bent section; the first synchronous part 12 is arranged in parallel with the straight section of the first plate body 11; and the first sliding block 13 is arranged on the bent section of the first plate body 11 and is movably connected with the first synchronous part 12.

[0024] It should be noted that the first synchronous part 12 is arranged in parallel with the straight section of the first plate body 11, which ensures that the synchronous part can be consistent with the straight section of the first plate body 11 during the measurement process, thereby providing an accurate measurement reference. By arranging the sliding block, the first synchronous part 12 can always be parallel with the straight section of the first plate body 11, thereby ensuring the accuracy and consistency of the measurement. The cooperative work of the first plate body 11, the first synchronous part 12 and the first sliding block 13 enables the first indicating assembly 1 to flexibly and accurately measure the angle and length.

[0025] In some examples, further, the second indicating assembly 2 comprises a second plate body 21, a second synchronous part 22 and a second sliding block 23. The second plate body 21 is divided into a straight section and a bent section. The end of the second plate body 21 is clamped with a nut and is overlapped with the first plate body 11. The second synchronous part 22 is arranged in parallel with the straight section of the second plate body 21. The end of the second synchronous part 22 is clamped with a nut and is overlapped with the first synchronous part 12. The second sliding block 23 is installed on the bent section of the second plate body 21 and is movably connected with the second synchronous part 22.

[0026] It should be noted that the second synchronous part 22 is arranged in parallel with the straight section of the second plate body 21 and is overlapped with the first synchronous part 12 through the nut. Thus, the second indicating assembly 2 can be adjusted independently while keeping synchronization with the first indicating assembly 1 to adapt to different measurement requirements. The first synchronous part 12 and the second synchronous part 22 can be synchronously rotated under the action of the sliding block along with the rotation of the first plate body 11 and the second plate body 21, so as to facilitate accurate positioning. In actual use, the user can adjust the positional relationship between the second plate body 21 and the second synchronous part 22 according to the needs, and accurately mark the cutting line and the angle through the rotation of the first plate body 11 and the second plate body 21, so as to realize fast and accurate measurement and marking without complex calculation or auxiliary lines. The efficiency and accuracy of measurement are improved, and the device is particularly suitable for occasions where the cutting line and the angle need to be determined quickly.

[0027] In some examples, further, the first plate body 11, the second plate body 21, the first synchronous part 12 and the second synchronous part 22 are all provided with scales. The scales can make the device multi-purpose. The second plate body 21 and the second synchronous part 22 can cooperate to obtain the width of the right-end profile. Similarly, the first plate body 11 and the first synchronous part 12 can cooperate to obtain the width of the left-end profile.

[0028] In some examples, further, the limiting assembly 5 comprises a connecting rod 51, which is provided with a strip-shaped through hole 52. The overlapping part of the first synchronous part 12 and the second synchronous part 22 can move along the length direction of the through hole 52. Two hand screws 53 are respectively screwed with the nuts.

[0029] It should be noted that the role of the connecting rod 51 is to connect the end of the first indicating assembly 1 and the second indicating assembly 2, allowing rotation between the two assemblies to facilitate adjustment to the desired angle. One end of the connecting rod 51 is rotationally connected to the connection between the first plate body 11 and the second plate body 21, ensuring coordinated movement between the two assemblies. The connecting rod 51 has a through hole 52, which allows the connection between the first synchronous part 12 and the second synchronous part 22 to move accordingly when the angle between the first plate body 11 and the second plate body 21 changes. The hand screw 53 is used to fix and lock the angle between the first plate body 11 and the second plate body 21, the first synchronous part 12 and the second synchronous part 22, and ensures that there is no displacement during measurement and marking by screwing with the nut. In actual operation, the user first adjusts the angle between the first plate body 11 and the second plate body 21, then the first synchronous part 12 and the second synchronous part 22 rotate accordingly, and finally the hand screw 53 is used for position locking to ensure the accuracy and stability of the measurement. The user can quickly and accurately set the cutting line and angle, improving work efficiency, while avoiding errors caused by manual calculation or inaccurate marking.

[0030] In some examples, further, the identification assembly 3 comprises: a protractor 31 and an indicating rod 32, the protractor 31 is arranged at the end of the second plate body 21; the number of indicating rods 32 is two, and one of the indicating rods 32 is installed at the end of the first plate body 11 and fits the protractor 31, and the other indicating rod 32 is arranged at the end of the connecting rod 51 and fits the protractor 31.

[0031] It should be noted that the protractor 31 is used to directly read the angle. Two indicating rods 32 are used to mark and confirm the angle, one of which is installed at the end of the first plate body 11 and can accurately read the angle formed between the first plate body 11 and the second plate body 21. The other indicating rod 32 is arranged at the end of the connecting rod 51 to ensure that the cutting angle can be accurately read and marked when the connecting rod 51 is adjusted to fix the angle between the first plate body 11 and the second plate body 21. Through the coordinated work of the two indicating rods 32, the user can directly read the required cutting angle on the protractor 31, so as to accurately mark the cutting line and angle on the cut material, simplifying the measurement and marking process, and making the cutting work more efficient and accurate.

[0032] According to Fig. 3 As shown in FIG. 6, angle B (cutting angle of the right end profile), due to simple geometric relationship, angle C (cutting angle of the left end profile) can be derived, that is, angle C = 360°-angle A-angle B, that is, all the required cutting angles are obtained. Use the bench saw, or directly draw a auxiliary line on the profile to be cut along the connecting rod 51, and cut directly with an angle grinder.
