[0012] In the figure: 1- telescopic scale a, 2- telescopic slide a, 3- telescopic scale b, 4- telescopic slide b, 5- telescopic scale c, 6- telescopic slide c, 7- sliding nozzle. DETAILED DESCRIPTION

[0013] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] like Figure 1 As shown, a convenient ruler for drawing lining layered casting lines is mainly composed of a telescopic ruler group, a slide plate assembly and a sliding nozzle 7, wherein the telescopic ruler group is installed at the bottom of the slide plate assembly, and the sliding nozzle 7 is slidably installed on the slide plate assembly.

[0015] In order to make the entire drawing ruler small in size and easy to store and carry, the slide assembly is a retractable slide assembly, which consists of a retractable slide a 2, a retractable slide b 4 and a retractable slide c 6. The retractable slide a 2 and the retractable slide b 4 are both hollow cylinders. The retractable slide a 2 can be slidably mounted on the outside of the retractable slide b 4, and the retractable slide b 4 can be slidably mounted on the outside of the retractable slide c 6. The slide assembly can be adjusted to a required length by sliding relative to each other. The slide assembly is provided with a horizontal through groove along the length direction, and the sliding nozzle 7 can be slidably installed in the horizontal through groove. It is best that the sliding nozzle 7 consists of a round tube nozzle and a vertical sliding rod, and the round tube nozzle can be slidably installed in the horizontal through groove through the vertical sliding rod.

[0016] The telescopic scale set is composed of at least two telescopic scales and installed at the bottom of the slide assembly. Preferably, the corresponding slide assembly is provided with a telescopic scale a1, a telescopic scale b3 and a telescopic scale c5, which are respectively installed at the bottom of the telescopic slide a2, the telescopic slide b4 and the telescopic slide c6. The telescopic scale preferably adopts a telescopic scale rod, which can be better made into a telescopic structure than a general scale, and the length adjustment during use is more accurate. At the same time, the telescopic scale set is hinged at the bottom of the slide assembly and can be folded and stored.

[0017] In the specific use process, the surveyor first draws a reference line at the position of the short side wall, pulls out the telescopic slide plate b 4 and the telescopic slide plate c 6 to the appropriate length, and adjusts the length of the telescopic scale a 1, the telescopic scale b 3 and the telescopic scale c 5 according to the required spacing of the layered casting. The lower end of the telescopic scale after the length adjustment is aligned with the reference line, the slide plate assembly is close to the surface to be drawn, the spray can nozzle is inserted into the sliding nozzle 7, and the spray can is slid in the horizontal groove through the sliding nozzle 7 to spray the casting line to complete the drawing of this section. When drawing the next casting line, the telescopic scale a 1, the telescopic scale b 3 and the telescopic scale c 5 are aligned with the casting line drawn in the previous one, and this cycle is repeated until the drawing is completed.
