[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 4 As shown, this embodiment provides a hole-opening tool for an insulation board, comprising:

[0028] The base 1 includes a middle plate 100 and a plurality of sliding cavities 101 connected to the middle plate 100 and extending radially toward the outside of the middle plate 100;

[0029] The positioning column 2 penetrates the interior of the middle plate 100 and extends to the lower area of ​​the middle plate 100;

[0030] The hot melt portion 3 is movably disposed inside the sliding cavity 101 and is locked at a designated position inside the sliding cavity 101;

[0031] Among them, multiple hot melt parts 3 are all located on the outside of the positioning column 2, and the bottom ends of multiple hot melt parts 3 are all on the same virtual circular trajectory. After the hot melt parts 3 are powered on and heated, they rotate around the positioning column 2 to form the opening part of the insulation board.

[0032] In this embodiment, specifically, the shape of the middle plate 100 is a square.

[0033] In this embodiment, specifically, on the top end surface and the bottom end surface of the sliding cavity 101, a first open area 1010 and a second open area 1011 corresponding to each other are formed along the length direction of the sliding cavity 101. The front end of the sliding cavity 101 is an open structure, and a spacing area is provided between the front end of the sliding cavity 101 and the positioning column 2. A horizontally arranged strip hole 1012 is provided on one of the side walls of the sliding cavity 101. The strip hole is connected to the interior of the sliding cavity 101.

[0034] The formed spacing area makes it easy to take the hot melt portion 3 in an unlocked state out of the sliding cavity 101 .

[0035] In this embodiment, further, the number of the sliding cavities 101 is four, and the four sliding cavities 101 all extend radially toward the outside of the middle plate 100 , and the edge of the bottom plate of each sliding cavity 101 is connected to one edge of the middle plate 100 adjacent thereto.

[0036] Among the four sliding cavities 101 , two sliding cavities 101 with corresponding positions are located on the same axis.

[0037] In this embodiment, specifically, the positioning post 2 passes through the axis of the middle plate 100 and then extends to the lower area of ​​the middle plate 100 .

[0038] Preferably, the bottom end of the positioning column 2 is a sharp structure. This design facilitates the bottom end of the positioning column 2 to be embedded in the insulation board, thereby improving the positioning performance of the hole-opening tool.

[0039] In this embodiment, specifically, each hot melt part 3 includes a sliding part, a hot melt knife 302 disposed inside the sliding part, and a locking part 303 for locking the sliding part inside the sliding cavity 101. The sliding part is movably disposed inside the sliding cavity 101, and is locked at a designated position inside the sliding cavity 101 by the locking part 303.

[0040] Furthermore, the sliding portion includes a longitudinal body 300 for the hot melt knife 302 to penetrate, and corresponding sliding members 301 respectively arranged on both sides of the longitudinal body 300 and connected to the longitudinal body 300 .

[0041] Preferably, the sliding member 301 may be a pulley to facilitate the movement of the sliding part inside the sliding cavity 101 .

[0042] Furthermore, the width of the longitudinal body 300 is the same as the width of the first open area 1010, so that the top end surface of the longitudinal body 300 is located in the upper area of ​​the sliding cavity 101. The bottom end surface of the longitudinal body 300 is located inside the sliding cavity 101, and a through hole for the hot melt knife 302 to penetrate is formed inside the longitudinal body 300.

[0043] Since the width of the through hole is not greater than the width of the second open area 1011 , the bottom end of the hot melt knife 302 can extend to the lower area of ​​the sliding cavity 101 through the second open area 1011 after passing through the through hole.

[0044] Furthermore, the locking part 303 includes a bolt and a rotating part, wherein one end of the bolt is connected to the rotating part. By manipulating the spiral part, the other end of the bolt passes through the strip hole 1012 and abuts against the longitudinal body 300, thereby fixing the longitudinal body 300 at a designated position in the sliding cavity 101.

[0045] In addition, a scale is provided on the top end surface of each sliding cavity 101 and / or the side wall surface with the strip hole 1012. This design facilitates adjusting the position of each hot melt part 3 in the sliding cavity 101 to a specified position, thereby ensuring the formation of a circular hole effect.

[0046] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
