During the rotation of the fan blades 15, a certain airflow will be generated to blow air to the single frequency modulation simulation tester 1 and the heat sink 17, so that the heat can be dissipated from both. In this process, the poor heat dissipation effect of the single frequency modulation simulation tester 1 can be reduced, resulting in the single frequency modulation simulation tester 1 being used outdoors. The high temperature outdoors plus the heat generated by the single frequency modulation simulation tester 1 during operation can easily damage its internal electronic components, affecting the use effect of the single frequency modulation simulation tester 1. At this time, the heat sink 17 and the fan blades 15 are set, and the heat dissipation speed of the single frequency modulation simulation tester 1 can be increased, thereby improving the stability of the single frequency modulation simulation tester 1 during use.

At this time, release the pull plate 23, and the first spring 21 will apply a certain reaction force to the insertion rod 22, pushing the insertion rod 22 onto the side wall of the slot 24 to make it stuck, thereby fixing the slider 12. In this process, the poor fixing effect of the drive motor 14 can be reduced, resulting in the slider 12 easily sliding off the inner wall of the guide rail 11 when it is accidentally pulled, causing the drive motor 14 to fall and be damaged. At this time, the insertion rod 22 is set to increase the fixing effect of the slider 12 on the inner wall of the guide rail 11, thereby improving the fixing effect of the drive motor 14.

[0025] like Figure 1-4 As shown, a pair of telescopic rods 3 are hinged on the side walls of the mounting frame 13; the pair of telescopic rods 3 are symmetrically arranged on both sides of the mounting frame 13 and have the same structure; the ends of the telescopic rods 3 are hinged on the same baffle plate 31; a second spring 32 is fixedly connected between the baffle plate 31 and the mounting frame 13; when in use, when the drive motor 14 is accidentally hit by an external object during use, the foreign object will first hit the wall of the baffle plate 31, at this time the baffle plate 31 will approach the mounting frame 13 and squeeze the second spring 32, so that the second spring 32 performs a telescopic movement, and the telescopic rod 3 will perform a telescopic movement at the same time, at this time, under the elastic action of the second spring 32, the impact force generated by the collision will be buffered, in this process, the drive motor 14 can be reduced in the process of not having a protective effect during use, resulting in the drive motor 14 being easily damaged when being hit by an external object, affecting the use effect, at this time, the baffle plate 31 is set, thereby playing a protective buffering role for the drive motor 14.

[0026] like Figure 1-4As shown, a pair of fixing rods 4 are fixedly connected to the side wall of the mounting frame 13; the pair of fixing rods 4 are symmetrically arranged on both sides of the mounting frame 13 and have the same structure; a guide plate 41 is fixedly connected to the end of the fixing rod 4; a pair of through holes 42 are symmetrically opened on the side wall of the guide plate 41; when in use, the airflow generated by the rotation of the fan blades 15 will contact the guide plate 41, and under the action of the guide plate 41, the airflow can be dispersed, and at the same time, part of the airflow will pass through the through holes 42 and blow to the bottom of the guide plate 41, thereby increasing the blowing range of the airflow. In this process, the range of the airflow blown out by the fan blades 15 can be reduced and concentrated, resulting in poor heat dissipation effect on the primary frequency modulation simulation tester 1, affecting the use effect of the primary frequency modulation simulation tester 1, at this time, the guide plate 41 and the through holes 42 are set, and then the blowing range of the airflow can be increased, and the heat dissipation effect of the primary frequency modulation simulation tester 1 and the heat sink 17 can be improved.

[0027] like Figure 1-4 As shown, a pair of limit plates 5 are fixedly connected to the side walls of the guide rail 11; the pair of limit plates 5 are symmetrically arranged on both sides of the guide rail 11 and have the same structure; a plurality of sponge pads 51 are evenly fixedly connected to the side walls of the limit plates 5; when in use, by inserting the slider 12 onto the inner side wall of the guide rail 11, the slider 12 will contact the limit plates 5 on both sides of the guide rail 11, and under the action of the inclined surface of the limit plate 5, the slider 12 will slide toward the middle of the limit plates 5 on both sides. At the same time, the sponge pads 51 can block the direct contact between the slider 12 and the limit plate 5, thereby reducing the wear caused to the slider 12 when it contacts the limit plate 5. In this process, it can reduce the difficulty in aligning the slider 12 when inserting it onto the inner side wall of the guide rail 11, making it difficult to insert the slider 12 onto the inner side wall of the guide rail 11. At this time, the limit plate 5 is set, thereby playing a limiting role when the slider 12 is inserted into the inner side wall of the guide rail 11, and at the same time, the sponge pads 51 can play a protective role for the limit plate 5.

[0028] like Figure 1-4 As shown, a plurality of elastic sheets 6 are evenly fixed to the side walls of the baffle 31; during use, when the baffle 31 is impacted and squeezed toward the mounting frame 13, the elastic sheet 6 is squeezed between the baffle 31 and the mounting frame 13 and deformed, and a certain reaction force is applied under the elastic action of the elastic sheet 6. In this process, the poor buffering effect of the second spring 32 can be reduced, resulting in the drive motor 14 being easily damaged when the baffle 31 is impacted. At this time, the elastic sheet 6 is provided to further play a buffering role when the baffle 31 is impacted.

[0029] like Figure 1-4As shown, a copper tube 7 is fixedly connected to the side wall of the heat sink 17; the copper tube 7 passes through the wall of the heat sink 17 and is fixed thereto; when in use, multiple heat sinks 17 can be connected in series through the copper tube 7 to connect them together, and the heat of the heat sink 17 itself can be connected in series through the copper tube 7 to improve the heat dissipation effect. In this process, the heat dissipation speed of the heat sink 17 can be reduced, which results in the primary frequency modulation simulation tester 1 being easily damaged when the heat is high. At this time, the copper tube 7 is set to increase the heat dissipation effect of the primary frequency modulation simulation tester 1 and improve the heat dissipation speed of the heat sink 17.

[0030] like Figure 1-4 As shown, the side wall of the slider 12 is fixedly connected with a rubber pad 8; the rubber pad 8 and the guide rail 11 are in sliding cooperation; when in use, by inserting the slider 12 into the inner wall of the guide rail 11, the rubber pad 8 will contact with the guide rail 11 and generate a certain friction force to pre-fix the slider 12. In this process, after the slider 12 is inserted into the inner wall of the guide rail 11, the slider 12 can be accidentally pulled when the insertion rod 22 is inserted into the side wall of the slot 24, causing the slider 12 to slide and affect the insertion of the insertion rod 22. At this time, the rubber pad 8 is set to play a role in pre-fixing the slider 12.

[0031] When working, first hold the mounting frame 13, align the slider 12 with the guide rail 11, and insert the slider 12 into the inner wall of the guide rail 11. Since the guide rail 11 has a certain length, the slider 12 can be lowered to slide out from the inner wall of the guide rail 11 to fix the drive motor 14. Then, when the single frequency modulation simulation tester 1 is working, the heat generated by the single frequency modulation simulation tester 1 can be absorbed by the heat conduction plate 16 and tightly fitted with the single frequency modulation simulation tester 1, and the heat can be conducted to the wall of the heat sink 17, and the absorbed heat can be released through the heat sink 17. At the same time, the drive motor 14 is started, and the fan blades 15 can be driven to rotate under the action of the drive motor 14. When the fan blades 15 rotate During the process, a certain amount of airflow will be generated to blow air to the frequency modulation simulation tester 1 and the heat sink 17, so that the two can dissipate heat. When in use, first hold the pull plate 23 and pull it, and pull the plug rod 22 to one side of the pull plate 23. At this time, the first spring 21 will be squeezed by the plug rod 22 and will perform a telescopic movement. After that, when the slider 12 is fully inserted into the inner wall of the guide rail 11, the plug rod 22 will correspond to the position of the slot 24. At this time, the pull plate 23 is released, and the first spring 21 will exert a certain reaction force on the plug rod 22, pushing the plug rod 22 to the side wall of the slot 24, making it stuck, and fixing the slider 12. When in use, when the drive motor 14 is accidentally hit by foreign objects during use When the fan 15 is hit, the foreign object will first hit the wall of the baffle plate 31. At this time, the baffle plate 31 will approach the mounting frame 13 and squeeze the second spring 32, so that the second spring 32 will perform a telescopic movement. At the same time, the telescopic rod 3 will perform a telescopic movement. At this time, the impact force generated by the collision will be buffered under the elastic action of the second spring 32. When in use, the airflow generated by the rotation of the fan blades 15 will contact the guide plate 41. Under the action of the guide plate 41, the airflow can be dispersed. At the same time, part of the airflow will pass through the through hole 42 and blow to the bottom of the guide plate 41, thereby increasing the blowing range of the airflow. When in use, by inserting the slider 12 onto the inner wall of the guide rail 11, the slider 12 will contact the two sides of the guide rail 11. When the baffle plate 31 is in contact with the limit plate 5, under the action of the inclined surface of the limit plate 5, the slider 12 will slide toward the middle of the limit plates 5 on both sides. At the same time, the sponge pad 51 can prevent the slider 12 from directly contacting the limit plate 5, thereby reducing the wear caused to the slider 12 when it contacts the limit plate 5. When in use, when the baffle plate 31 is impacted and squeezed to approach the mounting frame 13, the elastic sheet 6 is squeezed between the baffle plate 31 and the mounting frame 13 and deformed, and a certain reaction force is applied under the elastic action of the elastic sheet 6. When in use, multiple heat sinks 17 can be connected in series through the copper tube 7 to connect them together, and the heat of the heat sink 17 itself can be connected in series through the copper tube 7 to improve the heat dissipation effect.
