For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0017] See also Figure 1-Figure 4 , which is convenient for cost consulting and calculation work, comprises a main ruler 10 and a sub-rule 11; the vertical section of the main ruler 10 is set to a right-angle trapezoid, and a sub-rule moving storage slot 14 is opened in the right-angle side of the main ruler 10; a swing positioning ring 20 is installed at one end of the sub-rule 11, and the swing positioning ring 20 is placed in the sub-rule moving storage slot 14 for sliding setting, and the movable swing positioning ring 20 is placed in the position inside the sub-rule moving storage slot 14, so as to adjust the position change between the sub-rule 11 and the main ruler 10, and the swing positioning ring 20 placed in the sub-rule moving storage slot 14 is placed in the sub-rule moving storage slot 14. 0 is provided with a rotating member, and the rotating member is used to adjust the placement angle of the secondary ruler 11 relative to the main ruler 10. At the same time, the thickness of the secondary ruler 11 is less than the thickness of the secondary ruler mobile storage slot 14, and the length of the secondary ruler 11 is less than the length of the secondary ruler mobile storage slot 14. The rotating member and the swing positioning ring 20 are placed in the secondary ruler mobile storage slot 14 for sliding cooperation, so that the secondary ruler 11 is controlled to be stored in the secondary ruler mobile storage slot 14. An adjustable secondary ruler 11 is provided on one side of the main ruler 10, which increases the measuring range of the entire positioning ruler and is convenient for carrying and storage.
[0018] In the embodiment of the present invention, the vertical section of the secondary ruler 11 is set to be an isosceles trapezoid, and the inclined surfaces of the main ruler 10 and the secondary ruler 11 are both engraved with scale lines 12, and the scale lines 12 are used to measure the length. The main ruler 10 corresponding to the top of the secondary ruler moving storage slot 14 is provided with a slideway 13 with the same length as the secondary ruler moving storage slot 14, and the top of the rotating part extends to the outer top of the slideway 13 and moves along the inside of the slideway 13;
[0019] The rotating member includes a screw rod 15 placed inside the slideway 13 for movement. A secondary scale sliding positioning nut 16 is threadedly connected to the screw rod 15 located above the slideway 13. By rotating the secondary scale sliding positioning nut 16, a limit block is installed at the bottom end of the screw rod 15. A limit slot is provided in the inner bottom wall of the secondary scale moving storage slot 14 corresponding to the limit block. The limit slots are distributed along the length direction of the secondary scale moving storage slot 14. The limit block is placed in the limit slot and slides, so that the screw rod 15 can move along the length direction of the slideway 13 while being fixed in the vertical direction.
[0020] The contact force between the bottom of the secondary scale sliding positioning nut 16 and the upper surface of the slideway 13 is adjusted by rotating the secondary scale sliding positioning nut 16, thereby limiting the movement of the screw rod 15. At the same time, a secondary scale swing positioning nut 21 is threadedly connected to the screw rod 15 inside the secondary scale moving storage slot 14. The screw rod 15 located at the lower side of the secondary scale swing positioning nut 21 is rotatably assembled with the swing positioning ring 20. The secondary scale swing positioning nut 21 is rotated to adjust the contact force of its bottom on the swing positioning ring 20, thereby limiting the rotation between the swing positioning ring 20 and the screw rod 15. That is, after the swing positioning ring 20 is adjusted to the desired angle, the rotation is controlled by rotating the secondary scale swing positioning nut 21.
[0021] It should be noted that the width of the secondary ruler movable storage slot 14 is set within a reasonable size, that is, the user's fingers can be smoothly inserted into the secondary ruler movable storage slot 14 to directly control the rotation of the secondary ruler swing positioning nut 21. In this way, the secondary ruler swing positioning nut 21 can be controlled at any time to limit the rotation of the swing positioning ring 20 without the aid of external tools.
[0022] In one embodiment of the present invention, an extension block is installed at the lower part of the end wall of the secondary scale 11 away from the main scale 10, and a fixed column 18 is installed on the top of the extension block. A ring 19 is rotatably mounted on the fixed column 18, and an angle measuring scale 17 is installed on one side of the ring 19. The rotational mounting between the ring 19 and the fixed column 18 facilitates the installation and removal of the angle measuring scale 17 and the secondary scale 11. At the same time, the angle measuring scale 17 is used to measure the angle. When the secondary scale 11 is stored in the secondary scale movable storage slot 14, the angle measuring scale 17 needs to be detached from the end of the secondary scale 11.
[0023] The working principle of the utility model is: in the idle position of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical connections are completed in a sequential working order. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, according to the requirements of the measurement work, the main ruler 10 and the auxiliary ruler 11 are used to perform corresponding measurements. The main ruler 10 is operated directly for measurement. When the auxiliary ruler 11 is used, according to the distribution of the measured position, the auxiliary ruler 11 is first swung out from the auxiliary ruler mobile storage slot 14, and the auxiliary ruler 11 and the main ruler 10 are controlled within a reasonable placement angle. At the same time, the end of the auxiliary ruler 11 is placed at a reasonable position of the main ruler 10, and then the scale lines 12 on both sides of the auxiliary ruler 11 are used for measurement. At the same time, an angle measuring ruler 17 is installed at the end of the auxiliary ruler 11 as needed, and the angle measuring ruler 17 is used to measure the arc, thereby expanding the effective measurement range of the positioning ruler.
[0024] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
