[0022] For this specific embodiment, by pressing the pressing piece 105, the pressing piece 105 slides in the cylinder 106, and the pressing piece 105 presses the rotating plate 108. Under the cooperation of the pivot 107, the rotating plate 108 rotates, and then the rotating plate 108 cooperates with the recess 118, and then the block 110 is pushed outward, the block 110 cancels the block of the right angle ruler 101, and then the position of the vernier 102 is adjusted. After adjustment, the pressing piece 105 is loosened, and under the elastic force of the spring 109, the block 110 again blocks the right angle ruler 101, and then the vernier 102 is limited. Thus, the device can quickly adjust the position of the vernier 102, and is simple and convenient to install and disassemble, and has wide application range.

[0023] The side of the abutting block 110 has a groove 118, the cursor 102 is arranged on the right angle ruler 101, the first sliding frame 103 is sleeved outside the right angle ruler 101, and the first sliding frame 103 is fixedly connected with the lower end of the cursor 102, the shell 104 is fixedly connected with the front end of the first sliding frame 103, the cylinder 106 is fixedly arranged on the inner wall of the shell 104, one end of the pressing block 105 penetrates through the shell 104 and is slidably matched with the cylinder 106, the abutting block 110 penetrates through the shell 104 and the first sliding frame 103 and abuts against the right angle ruler 101, the two ends of the spring 109 are fixedly connected with the inner wall of the shell 104 and the front end of the abutting block 110 respectively, the rotating shaft 107 is rotatably connected with the shell 104 and is located in the interior of the shell 104, the rotating plate 108 is arranged on the rotating shaft 107, one end of the rotating plate 108 is located in the interior of the groove 118, and the other end of the rotating plate 108 is located behind the pressing block 105. By extruding the pressing block 105, the pressing block 105 slides in the cylinder 106, the pressing block 105 extrudes the rotating plate 108, and under the cooperation of the rotating shaft 107, the rotating plate 108 rotates, so that the rotating plate 108 cooperates with the groove 118, the abutting block 110 is pushed outwards, the abutting block 110 cancels the abutment with the right angle ruler 101, the position of the cursor 102 is adjusted, after the adjustment is completed, the pressing block 105 is loosened, under the elastic force of the spring 109, the abutting block 110 abuts against the right angle ruler 101 again, the cursor 102 is limited in position, and after the abutting block 110 returns to the original position, the rotating plate 108 also rotates back to the original position under the driving of the groove 118, so that the device can quickly adjust the position of the cursor 102, is simple and convenient to install and disassemble, and has wide application range.

[0024] Secondly, the sliding groove 111 is fixedly connected with the rear end of the pressing block 105, and one end of the rotating plate 108 is slidably matched with the sliding groove 111. When the pressing block 105 drives the rotating plate 108 to rotate, the sliding groove 111 is matched with the rotating plate 108, so that the rotating plate 108 cannot be separated from the pressing position of the pressing block 105, and the rotating plate 108 cannot rotate, and the sliding groove 111 makes the rotating plate 108 rotate more stably.

[0025] Meanwhile, the main ruler 112 is arranged on the cursor 102, the base ruler 113 is arranged on the main ruler 112, and the straight ruler 114 is arranged on the horizontal moving unit. Measurement work is performed through cooperation between the main ruler 112, the cursor 102, the base ruler 113 and the straight ruler 114.

By rotating the rotating block 117, the bolt 116 abuts against the ruler 114, and then the right angle ruler 101 is fixed on the ruler 114. When it is necessary to adjust the position of the right angle ruler 101, the rotating block 117 is twisted in the opposite direction, the bolt 116 is away from the threaded hole 119, and then the abutting against the ruler 114 is separated, and then the position of the right angle ruler 101 can be adjusted.

[0027] In addition, the main ruler 112 has a first scale line 120, and the cursor 102 has a second scale line 121. By the first scale line 120 and the second scale line 121, the main ruler 112 and the cursor 102 can be used for accurate measurement work, and the second scale line 121 is more advanced than the first scale line 120, so that the cursor 102 can realize fine measurement of an angle.

[0028] When the universal angle ruler is used, the pressing block 105 is extruded, the pressing block 105 slides in the cylinder 106, the pressing block 105 extrudes the rotating plate 108, and the rotating plate 108 rotates under the cooperation of the rotating shaft 107, the rotating plate 108 cooperates with the recess 118, the resisting block 110 is pushed outwards, the resisting block 110 cancels the resistance with the right angle ruler 101, the position of the cursor 102 is adjusted, after the adjustment is completed, the pressing block 105 is loosened, the resisting block 110 again resists the right angle ruler 101 under the elastic force of the spring 109, the cursor 102 is limited, the device can quickly adjust the position of the cursor 102, is simple and convenient to install and disassemble, and has wide application range; when the pressing block 105 pushes the rotating plate 108 to rotate, the sliding groove 111 is adapted with the rotating plate 108, the rotating plate 108 is prevented from being separated from the pressing position of the pressing block 105, the situation that the rotating plate 108 cannot rotate is avoided, and the rotating plate 108 rotates more stably; the main ruler 112, the cursor 102, the base ruler 113 and the ruler 114 are cooperated to carry out measurement work; the rotating block 117 is rotated, the screw 116 resists the ruler 114, the right angle ruler 101 is fixed on the ruler 114, when the position of the right angle ruler 101 needs to be adjusted, the rotating block 117 is twisted in the opposite direction, the screw 116 is away from the threaded hole 119, the resistance of the right angle ruler 101 to the ruler 114 is avoided, and the position of the right angle ruler 101 can be adjusted; the first scale line 120 and the second scale line 121 are used, the main ruler 112 and the cursor 102 can carry out accurate measurement work, and the second scale line 121 is higher than the first scale line 120, so that the cursor 102 can realize fine measurement of an angle.
