[0002] A calibrator, also known as a calibration instrument, is mainly used in the connection of square tubes or steel tubes to calibrate and adjust them to ensure the accuracy and reliability of the dimensions after the connection. Currently available calibrators are designed for straight connections and for perpendicular connections.
[0003] Most existing calibration instruments are designed for straight and right-angle connections and cannot adjust the angle. However, in practical applications, in addition to straight and right-angle connections between square tubes and steel pipes, there is also a need for connections at other angles.
[0004] Therefore, it is necessary to provide a calibration instrument to address the aforementioned technical problems.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides a calibration instrument, including: a main rod and a clamping device;
[0008] One end of the main rod is fixed with a first rotating shaft, and a first correction component and a second correction component are rotatably connected to the first rotating shaft. The first correction component and the second correction component are both chiseled with a first sliding groove. A moving component is slidably arranged on the main rod. A push rod is arranged inside the main rod. A scale is arranged on the main rod.
[0009] The clamping device is installed on the first and second alignment members. The clamping device includes a pair of fixed bases. Each pair of fixed bases has a second sliding groove. A second slider is slidably arranged in the second sliding groove. A clamping plate is fixed on the pair of second sliders. A control box is fixed between the pair of main rods. A drive shaft is rotatably arranged on the control box.
[0010] In one or more embodiments of this utility model, a pair of crossbars are fixed on both sides of the movable member. The movable member drives the second rotating shaft to move through the crossbars. The ends of the pair of crossbars away from the movable member are rotatably connected to the second rotating shaft for connecting the first slider.
[0011] In one or more embodiments of this utility model, a first slider is fixed at both ends of the second rotating shaft. The first slider is slidably disposed in the first groove. The second rotating shaft drives the first slider to move along the trajectory of the first groove, thereby realizing the adjustment of the angle between the first corrector and the second corrector.
[0012] In one or more embodiments of this utility model, a pair of movable rods are provided on both sides of the push rod for outwardly opening and clamping the movable part. Each pair of movable rods is chiseled with multiple inclined grooves. A push block corresponding to the inclined groove is fixed on the push rod.

The transmission shaft drives the gear to rotate, and the gear drives the pair of toothed plates to move in opposite directions.
[0015] In one or more embodiments of this utility model, a fixing block is fixed to one end of each pair of toothed plates, and a rotating rod is rotatably connected between each pair of fixing blocks and the clamping plate. When the toothed plates drive the fixing blocks to open outward, the fixing blocks push the clamping plate to move along the trajectory of the second slider sliding in the second groove through the rotating rod.
[0016] In one or more embodiments of this utility model, a third slide groove is cut into the control box, and a slide rail is fixed on the toothed plate. The slide rail is slidably disposed in the third slide groove, which limits the position of the toothed plate so that the toothed plate can only move along the trajectory direction of the third slide groove.
[0017] In one or more embodiments of this utility model, the transmission shaft is provided with a retaining ring and a second rotating handle fixed outside the control box. The second rotating handle is used to drive the transmission shaft to rotate, and the retaining ring is used to prevent the transmission shaft from rotating in the opposite direction.
[0018] In one or more embodiments of this utility model, a groove is chiseled on the toothed ring, and a locking plate is rotatably provided on the control box. One end of the locking plate is locked in the groove, and the transmission shaft is prevented from rotating in the reverse direction by locking the plate in the groove.

Detailed Implementation
[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0032] like Figures 1 to 8 As shown, a calibration instrument in one embodiment of the present invention includes: a main rod 1 and a clamping device 2.
[0033] like Figures 1 to 4 As shown, a first rotating shaft 101 is fixed to one end of the main rod 1. A first corrector 102 and a second corrector 103 are rotatably connected to the first rotating shaft 101. Different angle corrections are achieved by adjusting the angle between the first corrector 102 and the second corrector 103. Both the first corrector 102 and the second corrector 103 have a first sliding groove 104, and a first slider 105 moves along the first sliding groove 104. A movable member 106 is slidably mounted on the main rod 1 to move the crossbar 107. A push rod 109 is installed inside the main rod 1 to push a pair of movable rods 108 outwards, causing the movable rods 108 to clamp the movable member 106. A scale 115 is provided on the main rod 1. The movable member 106 adjusts its position on the main rod 1 according to the scale 115, so that the first corrector 102 and the second corrector 103 present different included angles. The scale 115 is marked with different angle values.
[0034] like Figures 1 to 4 As shown, a pair of crossbars 107 are fixed on both sides of the movable component 106. The movable component 106 drives the second rotating shaft 112 to move via the crossbars 107. The ends of the crossbars 107 away from the movable component 106 are rotatably connected to the second rotating shaft 112, which is used to connect the first slider 105. The first slider 105 is fixed to both ends of the second rotating shaft 112. The first slider 105 is slidably disposed in the first slide groove 104. The second rotating shaft 112 drives the first slider 105 to move along the trajectory of the first slide groove 104, thereby realizing the adjustment of the angle between the first corrector 102 and the second corrector 103.
[0035] like Figures 1 to 4As shown, a pair of movable rods 108 are provided on both sides of the push rod 109 to open and clamp the movable part 106. Each movable rod 108 has multiple inclined grooves 113. A push block 114 corresponding to the inclined groove 113 is fixed to the push rod 109. Pulling the push rod 109 outward causes the push block 114 to move along the inclined groove 113, thus opening the movable rod 108 outward. A screw 110 is fixed to one end of the push rod 109. The screw 110 is threaded onto the main rod 1 and connected to a first rotating handle 111. Rotating the first rotating handle 111 causes the screw 110 to pull the push rod 109 outward.
[0036] like Figure 1 and 5 As shown, the clamping device 2 is installed on the first calibrator 102 and the second calibrator 103. The clamping device 2 includes a pair of fixed bases 201, which are fixed to the first calibrator 102 and the second calibrator 103. Each of the fixed bases 201 has a second groove 202. A second slider 203 is slidably disposed within the second groove 202. A clamping plate 204 is fixed to the pair of second sliders 203. The clamping plate 204 is used to clamp the square tube or steel pipe to be connected. The second slider 203 drives the clamping plate 204 to move along the trajectory of the second groove 202. A control box 206 is fixed between the pair of main rods 1. A drive shaft 208 is rotatably disposed on the control box 206, which drives the gear 209 to rotate.
[0037] like Figures 5 to 8 As shown, a gear 209 is fixed at one end of the drive shaft 208 inside the control box 206. A pair of toothed plates 210 mesh on both sides of the gear 209. The drive shaft 208 drives the gear 209 to rotate, and the gear 209 drives the pair of toothed plates 210 to move in opposite directions. A fixing block 211 is fixed at one end of each pair of toothed plates 210. A rotating rod 205 is rotatably connected between each pair of fixing blocks 211 and the clamping plate 204. When the toothed plates 210 drive the fixing blocks 211 to open outward, the fixing blocks 211 push the clamping plate 204 along the trajectory of the second slider 203 sliding in the second slide groove 202 through the rotating rod 205, so that the clamping plate 204 can clamp and release the square tube or steel pipe.
[0038] like Figures 5 to 8As shown, a third groove 215 is carved inside the control box 206. A slide rail 216 is fixed on the toothed plate 210. The slide rail 216 is slidably disposed within the third groove 215, limiting the position of the toothed plate 210 so that it can only move along the trajectory direction of the third groove 215. A retaining ring 212 and a second rotating handle 207 are fixed outside the control box 206 to the drive shaft 208. The second rotating handle 207 is used to drive the drive shaft 208 to rotate, and the retaining ring 212 is used to prevent the drive shaft 208 from rotating in the opposite direction. A retaining groove 214 is carved on the retaining ring 212. A retaining plate 213 is rotatably disposed on the control box 206. One end of the retaining plate 213 is engaged in the retaining groove 214. The retaining plate 213 is engaged in the retaining groove 214 to prevent the drive shaft 208 from rotating in the opposite direction.
[0039] Working principle: First, determine the required angle between the two connected steel pipes or square tubes. Then, pull the moving part 106 to the appropriate scale. The moving part 106 drives a pair of second rotating shafts 112 to move through a pair of crossbars 107. The second rotating shafts 112 drive the first slider 105 to move along the trajectory of the first sliding groove 104, thereby adjusting the included angle between the first corrector 102 and the second corrector 103. After the angle is adjusted, rotate the first rotating handle 111. The first rotating handle 111 drives the push rod 109 to move outward. The screw 110 pulls the push rod 109 to move outward. When the push rod 109 moves outward, the push block 114 moves along the inclined groove 113 to push the moving rod 108 outward. The moving rod 108 clamps the moving part 106 to prevent the moving part 106 from moving, thereby fixing the included angle between the first corrector 102 and the second corrector 103.
[0040] Place the two steel pipes or square tubes to be connected on the fixed base 201, and then rotate the second rotating handle 207. The second rotating handle 207 drives the gear 209 to rotate through the transmission shaft 208. The gear 209 drives a pair of toothed plates 210 to move in opposite directions. The toothed plates 210 drive the fixed block 211 to open outward. The fixed block 211 pushes the clamping plate 204 along the trajectory of the second slider 203 sliding in the second slide groove 202 through the rotating rod 205, so that the clamping plate 204 clamps the square tube or steel pipe. Then, the clamping plate 213 is clamped in the slot 214 to prevent the transmission shaft 208 from rotating in the opposite direction and to prevent the clamping plate 204 from loosening its clamping of the square tube or steel pipe. After the connection is completed, simply press the end of the clamping plate 213 away from the slot 214, remove the clamping plate 213 from the slot 214, and reverse the second rotating handle 207 to release the square tube or steel pipe.
