DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0022] An embodiment of this application discloses a portable construction cost measuring ruler. Referring to Figures 1-4 , it includes a main ruler body 1. A groove is provided inside the main ruler body 1, and a secondary ruler body 2 is arranged inside the groove. One end of the secondary ruler body 2 is fixedly installed with a fixing rod 3;

[0023] The upper and lower ends of the outer surface of the fixed rod 3 are rotatably connected to the inside of one end of the main scale body 1. The secondary scale body 2 is rotatably connected to the main scale body 1 through the fixed rod 3. A pointer 4 is fixedly connected to the upper end of the fixed rod 3. The upper surface of the connection part between the main scale body 1 and the secondary scale body 2 is fixedly connected with an angular scale pattern 5. The tip of the pointer 4 corresponds to the angular scale pattern 5. By driving the fixed rod 3 to rotate with the secondary scale body 2, the fingertip of the pointer 4 points to different positions of the angular scale pattern 5, so as to facilitate the measurement of the angle by using the included angle between the secondary scale body 2 and the main scale body 1, enhancing the applicability of the device. A hidden groove 7 is opened inside the secondary scale body 2. A slide rail is opened at the bottom of the hidden groove 7. The inner surface of the hidden groove 7 is slidably connected with an extended scale plate 8 through the slide rail. By adding the extended scale plate 8 inside the secondary scale body 2, when it is necessary to adjust and increase the length of the measuring scale for measurement work, the limiting rod 10 is squeezed inward to make the second spring 9 stressed. At the same time, when the limiting rod 10 is disengaged from the positioning hole 11, the extended scale plate 8 can be pulled outward to increase the length of the entire measuring scale, improving the measurement efficiency. By opening the hidden groove 7 inside the secondary scale body 2, when the extended scale plate 8 is not needed, the extended scale plate 8 can be retracted into the hidden groove 7 for convenient storage. A number of positioning holes 11 are evenly opened on the side of the secondary scale body 2. A second spring 9 is fixedly installed on the side of the extended scale plate 8 close to the positioning hole 11. The other end of the second spring 9 is fixedly installed with a limiting rod 10. The outer surface of the limiting rod 10 is movably connected to the inside of the positioning hole 11. It is convenient to adjust the extended length of the extended scale plate 8 by connecting the limiting rod 10 to different positioning holes 11, making it more convenient to use. And through the reset effect of the second spring 9, when the extended scale plate 8 is adjusted to the appropriate position, the second spring 9 drives the outer side of the limiting rod 10 to be movably connected to the inside of the positioning hole 11, thereby locking the extended scale plate 8 and ensuring the stability of the device during measurement and making it more convenient to use. Two chutes 61 are evenly opened at the left end of the main scale body 1. A limiting baffle 62 is arranged outside the chutes 61. Two sliders 63 are evenly installed on the inner surface of the limiting baffle 62. The two sliders 63 are slidably connected to the inner surface of the chutes 61. A first spring 64 is fixedly installed on the inner surface of the two sliders 63. The other end of the first spring 64 is fixedly installed on the side of the inner surface of the chutes 61. The reset effect of the first spring 64 drives the limiting baffle 62 to translate toward one side of the groove, thereby locking the secondary scale body 2 inside the groove on the inner side of the main scale body 1, improving the overall convenience of the device, saving floor space and facilitating the staff to carry and use.

[0024] The implementation principle of a portable construction cost measuring ruler according to an embodiment of the present application is as follows: When using this device, push the limit baffle 62 towards the end away from the groove, so that the secondary ruler body 2 inside the groove can move. Then, rotate the secondary ruler body 2 to unfold it for measurement operations. The cooperation between the pointer 4 and the angle scale lines 5 enables the main ruler body 1 and the secondary ruler body 2 to conveniently measure the angle of an object. And when it is necessary to increase the measurement length, press the limit rod 10 so that it disengages from the positioning hole 11, and then pull the extension ruler plate 8 to slide outward on the inner side of the secondary ruler body 2. When it extends to the specified length, use the reset effect of the second spring 9 to connect the limit rod 10 to another positioning hole 11 inside to lock the extension ruler plate 8, thereby increasing the measurement distance of the entire measuring ruler.
