[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] Example: See Figure 1-3 In order to solve the problem that the current fuse function demonstrator is inconvenient to carry when used outside, resulting in the inconvenience of using the fuse demonstration device, and the direct observation method cannot be used to display the product effect to customers intuitively, a fuse function demonstrator is provided, including a demonstration box 1, and a protective demonstration structure is installed on the upper end of the demonstration box 1;

[0023] The protection demonstration structure includes: two binding posts 2, two copper wire mounting posts 3, three power switch components, a sliding rheostat 4, two fuse mounting posts 5, a flip protection component and a snap-on mounting component;

[0024] The two binding posts 2 are respectively installed on the wall surface of one side of the demonstration box 1, the two copper wire mounting posts 3 are respectively installed on the upper end of the inner wall of the demonstration box 1, and one of the copper wire mounting posts 3 is connected to one of the binding posts 2, one end of the three power-on switches 6 is connected to another copper wire mounting post 3, the sliding rheostat 4 is fixedly installed on the lower end of the inner wall of the demonstration box 1, and is connected to the other end of the three power-on switch components, the two fuse mounting posts 5 are installed on one side of the lower end of the inner wall of the demonstration box 1, and one of the fuse mounting posts 5 is connected to the other end of the sliding rheostat 4, and the other fuse mounting post 5 is connected to another binding post 2, the flip protection component is installed on one side of the lower end of the demonstration box 1, and is located on the outside of the two fuse mounting posts 5, and one end of the snap-fit ​​mounting component is hinged to one side of the demonstration box 1.

[0025] When using it outside, the device is portable and movable by cooperating with the provided snap-fit ​​installation component and the lifting handle 13 at the upper end of the demonstration box 1. When placed at a designated location for demonstration operation, the snap-fit ​​installation component is unfolded and the demonstration box 1 is supported. Then the sliding rheostat 4 is adjusted to the minimum, and the flip protection component is opened at the same time. The two ends of the prepared fuse are respectively connected to the two fuse mounting posts 5, and then the two ends of the copper wire are respectively connected to the two copper wire mounting posts 3. Then the flip protection component is reset, and the two terminals 2 are respectively connected to the positive and negative poles of the power supply, and then the three power-on switch components are turned on in sequence. When the three power-on switch components light up, when a current lower than the rated value of the fuse passes through the fuse After the fuse is turned on, the fuse does not change. Subsequently, the sliding rheostat 4 is adjusted. When the overload current passes through the fuse, the current exceeds the rated value and the fuse will melt, thereby cutting off the circuit to prevent the equipment or circuit from being damaged or causing a fire due to overload current. During the detection process, the diameter of the copper wire located at the upper end of the two copper wire mounting posts 3 is half of the internal wire. When the fuse is too large or a wire of other materials is mistakenly connected, the copper wire located at the upper end of the two copper wire mounting posts 3 will melt, and the internal wires and other components will be overload protected. The fuse position is protected by the set flip protection component. At the same time, the magnifying lens set in the protection frame 9 is used to facilitate the user to observe the changes in the fuse.

[0028] In order to observe and detect the power-on status of the fuse, the power-on status of the power-on light group 7 is controlled by operating the power-on switch 6. When the power-on light group 7 lights up, it indicates that the fuse is in normal condition. When the fuse blows due to overload, the power-on light group 7 is turned off.

[0029] Furthermore, the rollover protection assembly includes: a mounting seat 8 and a protection frame 9;

[0030] The mounting seat 8 is fixedly mounted on the inner wall of the demonstration box 1 , and one end of the protection frame 9 is hinged to the mounting seat 8 .
