[0002] A combined angle ruler is a tool for measurement and drawing, usually used in fields such as construction, engineering, and woodworking. It can help users accurately measure angles and lengths.

[0003] After retrieval, Chinese Patent Publication No.: CN220871653U discloses a combined angle ruler for positioning, including a scale. By providing a slide rail in the middle of the scale, the right angle ruler and the circle ruler can slide. By clamping the right angle ruler outside the scale, the required angle can be measured. And by installing a limiting rod at one end of the right angle ruler, by rotating the limiting rod to control the clamping force between the right angle ruler and the scale, the right angle ruler can be rotated arbitrarily to change the measurement angle. Then, a positioning component is installed on one side of the limiting rod. By sliding the positioning component to fit outside the scale, one side of the right angle ruler can be used as a reference to ensure that it reaches 90 degrees, facilitating the quick positioning of a right angle. The circle ruler installed inside the slide rail can measure the angles of various different objects, and when the initial angle needs to be positioned, only by rotating the reset component so that one end of it engages with the outside of the circle ruler, the positioning can be restored.

Connecting grooves 11 are opened at both the upper and lower parts of the scale 1 for cooperating with the connection of the right angle ruler 2. A positioning groove 13 is arranged at the front part of the connecting groove 11 at the top, which is located at the intersection of the extension lines of multiple angle marking lines 12, that is, at the center of the circle, and is used for cooperating with the positioning of the positioning component 24 and is adapted to the ball 244. A positioning hole 14 is opened in the middle of the connecting groove 11 for cooperating with the positioning rod 4. Multiple drawing holes 15 are opened at the rear part of the top surface of the connecting groove 11. The tip of a drawing pen can pass through different drawing holes 15 and cooperate with the positioning rod 4 in the positioning hole 14 for drawing circles with different diameters.

[0035] Please refer to Figure 4 - Figure 6 , an adjusting groove 21 is opened at the middle part of the left side of the right angle ruler 2 for cooperating with the angle adjustment between the scale 1 and the right angle ruler 2. An auxiliary groove 211 is opened at the front part of the top surface of the inner wall of the adjusting groove 21 for assisting in the connection and adjustment of the fixing member 23. An installation groove 22 is opened at the middle part of the right side of the right angle ruler 2 for cooperating with the connection of the positioning rod 4, and the positioning rod 4 is threadedly connected thereto. A fixing member 23 is arranged at the front part of the left side of the top surface of the right angle ruler 2 for cooperating with the positioning of the position of the right angle ruler 2 on the scale 1. A positioning component 24 is arranged at the rear part of the left side of the top surface of the right angle ruler 2 for cooperating with the angle positioning between the scale 1 and the right angle ruler 2. A limiting rod 25 is fixedly connected to the top surface of the left side of the lower part of the right angle ruler 2, and the limiting rod 25 is movably connected to the connecting groove 11 at the lower part for cooperating with the connection between the right angle ruler 2 and the scale 1.

[0036] Furthermore, the fixing member 23 includes a screw rod 231 for cooperating with the connection of the fixing member 23. The screw rod 231 penetrates through the right angle ruler 2 and is threadedly connected thereto. A rotating plate 232 is fixedly connected to the top of the screw rod 231 for rotating the screw rod 231. A fixing plug 233 is fixedly connected to the lower part of the screw rod 231. It is made of rubber and can be inserted into the upper connecting groove 11 to fix the position of the right angle ruler 2. The fixing plug 233 is movably connected to the upper connecting groove 11.

[0037] Further, the positioning component 24 includes an empty rod 241 for cooperating with the connection of various components. The empty rod 241 passes through the upper part of the right-angle ruler 2 and is threadedly connected thereto. A connecting rod 242 is slidably connected to the lower part of the empty rod 241 for cooperating with the positioning between the positioning component 24 and the positioning groove 13. A spring 243 is fixedly connected between the empty rod 241 and the connecting rod 242 for cooperating with the movement and reset of the connecting rod 242. A ball 244 is rotatably connected to the lower part of the connecting rod 242 for cooperating with the limitation of the positioning groove 13. The ball 244 is movably connected to the positioning groove 13.

[0038] Working principle: During use, the turntable 232 can be rotated to drive the screw rod 231 to move upward, so that the fixing plug 233 is separated from the connection groove 11. Then, the right-angle ruler 2 is slid along the connection groove 11 on the scale ruler 1 to a suitable position and the turntable 232 is rotated in the reverse direction to make the fixing plug 233 snap into the connection groove 11, so that the position between the right-angle ruler 2 and the scale ruler 1 is fixed. When it is necessary to change the angle between the scale ruler 1 and the right-angle ruler 2, the turntable 232 is rotated again to drive the fixing plug 233 to separate from the connection groove 11. At the same time, the empty rod 241 is rotated to drive the connecting rod 242 and the ball 244 connected to the connecting rod 242 downward until the ball 244 abuts against the lower inner wall of the connection groove 11. At the same time, the spring 243 is slightly compressed. Then, the right-angle ruler 2 is slid to drive the positioning component 24 to move toward the positioning groove 13 until it is felt that the ball 244 is pushed into the positioning groove 13 by the restoring force of the spring 243. Then, according to the angle scale line 12 on the scale ruler 1, the angle between the scale ruler 1 and the right-angle ruler 2 is adjusted to a suitable position. Then, the empty rod 241 can be rotated again to drive the connecting rod 242 and the ball 244 to be pressed downward together, so that the spring 243 is deformed again, and the connecting rod 242 abuts against the inner wall of the upper connection groove 11, so that the angle between the scale ruler 1 and the right-angle ruler 2 is fixed. When it is necessary to draw a circle, the empty rod 241 and the screw rod 231 are rotated in the reverse direction to drive the ball 244 and the fixing plug 233 away from the connection groove 11 respectively. Then, the right-angle ruler 2 is slid to separate it from the scale ruler 1. Then, the positioning rod 4 connected to the right-angle ruler 2 is taken out, the scale ruler 1 is placed at the position where the circle needs to be drawn, the positioning rod 4 is inserted into the positioning hole 14, and the drawing pen is inserted into the appropriate drawing port 15 according to the need. Keeping the position of the positioning rod 4 unchanged and dragging the drawing pen can draw a suitable circle.
