[0039] See also Figure 2 The first fixing section 10 includes a first plug-in portion 11 and a first breaking portion 12 which are arranged in sequence. The first breaking portion 12 is arranged at the end of the first plug-in portion 11.

[0040] The first plug-in portion 11 extends from the joint on the first template 200 and extends out of the first template 200. The extended first plug-in portion 11 is fixed to the first template 200 to fix the first template 200 and the first fixing section 10. In one embodiment, the first plug-in portion 11 is substantially rectangular. It is understood that the shape of the first plug-in portion 11 is not limited thereto. For example, in other embodiments, the first plug-in portion 11 is circular.

[0041] The first plug-in portion 11 is provided with a first mounting hole 111, and the first mounting hole 111 has a center line. The first mounting hole 111 is used to cooperate with the first template 200 so that the first template 200 and the first fixing section 10 are fixed. In one embodiment, a pin is fixed on the first template 200, and the pin extends into the first mounting hole 111 to fix the first template 200 and the first fixing section 10. The first mounting hole 111 is provided in the middle of the first plug-in portion 11, and the first mounting hole 111 is a circular hole. It can be understood that the opening position of the first mounting hole 111 is determined by the position of the pin and changes with the change of the position of the pin. The shape of the first mounting hole 111 is not limited thereto. For example, in other embodiments, the first mounting hole 111 is a square hole.

[0042] It should be noted that the center line of the first mounting hole 111 is the axis of the circular hole.

[0043] Two ends of the first breaking portion 12 are respectively disposed at the first plug-in portion 11 and the connecting section 30 , so that when the first plug-in portion 11 extends out of the first template 200 , the first plug-in portion 11 and the connecting section 30 are disconnected through the first breaking portion 12 .

[0044] The first breaking portion 12 is provided with a first breaking groove 121. The first breaking groove 121 is used to break the first plug-in portion 11 along the position of the first breaking groove 121 when the first plug-in portion 11 extends out of the first template 200. In one embodiment, the first breaking groove 121 is provided on two opposite sides of the first breaking portion 12, and the shape of the first breaking groove 121 is substantially V-shaped. It can be understood that the opening position and shape of the first breaking groove 121 are not limited thereto. For example, in other embodiments, the first breaking groove 121 is provided on one side of the first breaking portion 12, and the first breaking groove 121 is a rectangular groove.

[0045] See also Figure 2 The second fixing section 20 includes a second plug-in portion 21 and a second breaking portion 22 which are arranged in sequence. The second breaking portion 22 is arranged at the end of the second plug-in portion 21.

[0046] The second plug-in portion 21 extends from the joint on the second template 300 and extends out of the second template 300. The extended second plug-in portion 21 is fixed to the second template 300 to fix the second template 300 and the second fixing section 20. In one embodiment, the second plug-in portion 21 is substantially rectangular. It is understood that the shape of the second plug-in portion 21 is not limited thereto. For example, in other embodiments, the second plug-in portion 21 is circular.

[0047] The second plug-in portion 21 is provided with a second mounting hole 211, and the second mounting hole 211 has a center line. The second mounting hole 211 is used to cooperate with the second template 300 so that the second template 300 and the second fixing section 20 are fixed. In one embodiment, a pin is fixed on the second template 300, and the pin extends into the second mounting hole 211 to fix the second template 300 and the second fixing section 20. The second mounting hole 211 is provided in the middle of the second plug-in portion 21, and the second mounting hole 211 is a circular hole. It can be understood that the opening position of the second mounting hole 211 is determined by the position of the pin and changes with the change of the position of the pin. The shape of the second mounting hole 211 is not limited thereto. For example, in other embodiments, the second mounting hole 211 is a square hole. The center line of the second mounting hole 211 is approximately perpendicular to the center line of the first mounting hole 111, that is, the angle between the center line of the second mounting hole 211 and the center line of the first mounting hole 111 is between 80 degrees and 100 degrees, for example, the angle can be 80 degrees, 85 degrees, 90 degrees, 95 degrees, 100 degrees, etc.

[0048] It should be noted that the center line of the second mounting hole 211 is the axis of the circular hole.

[0049] Two ends of the second breaking portion 22 are respectively arranged on the second plug-in portion 21 and the connecting section 30 , so that when the second plug-in portion 21 extends out of the second template 300 , the second plug-in portion 21 and the connecting section 30 are disconnected through the second breaking portion 22 .

[0050] The second breaking portion 22 is provided with a second breaking groove 221. The second breaking groove 221 is used to break the second plug-in portion 21 along the position of the second breaking groove 221 when the second plug-in portion 21 extends out of the second template 300. In one embodiment, the second breaking groove 221 is provided on two opposite sides of the second breaking portion 22, and the shape of the second breaking groove 221 is substantially V-shaped.

[0051] See also Figure 2, the connecting section 30 is connected to the first fixing section 10, and is twisted at a preset angle to connect the second fixing section 20, so as to fix the first fixing section 10 and the second fixing section 20. In one embodiment, the first fixing section 10, the second fixing section 20 and the connecting section 30 are integrally formed. It can be understood that the fixing method of the first fixing section 10, the second fixing section 20 and the connecting section 30 is not limited thereto. For example, in other embodiments, the first fixing section 10, the second fixing section 20 and the connecting section 30 are welded and connected.

[0052] In one embodiment, the first template 200 and the second template 300 are aluminum alloy templates, the first template 200 is substantially "L" shaped, and the second template 300 is substantially flat. It is understood that the type and shape of the first template 200 and the second template 300 are not limited thereto. For example, in other embodiments, the first template 200 and the second template 300 are steel templates, and the shape of the first template 200 and the second template 300 is a triangular prism.

[0053] During operation, the first plug-in portion 11 is inserted into the joint of the first template 200, and the pin provided on the first template 200 is inserted into the first mounting hole 111 to fix the first template 200 and the first fixing section 10. The second plug-in portion 21 is inserted into the joint of the second template 300, and the pin provided on the second template 300 is inserted into the second mounting hole 211 to fix the second template 300 and the second fixing section 20, thereby fixing the first template 200 and the second template 300 through the pull tab 100.

[0054] Concrete is poured into the fixed first template 200 and the second template 300. After the concrete solidifies, a tool is used to knock the first plug-in portion 11 extending out of the first template 200 and the second plug-in portion 21 extending out of the second template 300, so that the first plug-in portion 11 is broken along the first breaking groove 121, and the second plug-in portion 21 is broken along the second breaking groove 221. At this time, the first template 200 and the second template 300 are fixed, and the pull tab 100 is located in the first template 200 and the second template 300.

[0055] The pull tab 100 provided above fixes the first fixing section 10 and the second fixing section 20 in the first template 200 and the second template 300 respectively, and connects the first fixing section 10 and the second fixing section 20 with the connecting section 30, and adjusts the angle between the center line of the first mounting hole 111 and the center line of the second mounting hole 211 to connect the first template 200 and the second template 300 at different angles, so that it is suitable for internal and external template systems with different angles and has strong applicability.
