Further, the support structure 4 is also provided. Through the support structure 4, the asphalt adhered after the measuring structure 2 is inserted can be effectively scraped and cleaned, playing a self-cleaning function, avoiding the trouble of cleaning after the asphalt cools and solidifies later, being flexible to use and suitable for popularization;

[0036] The measuring structure 2 includes a rectangular slider 201, a measuring insertion plate 202, a pointed head 203, a moving plate A 204, a connecting rod 205, an operating rod 206, a moving plate B 207, a limiting spring 208 and a threaded rod 209.
