A baffle 3 is fixedly installed on the inner wall of the card slot 21. A pull rod 31 is fixedly installed on the outer surface of the baffle 3. The outer surface of the baffle 3 is snap-fitted with the inner wall of the card slot 21, and one end of the pull rod 31 is fixedly connected to one side of the baffle 3. A placement plate 4 is fixedly installed on the inner wall of the outer frame 2. The outer diameter of the placement plate 4 is the same as the inner diameter of the outer frame 2, and the outer surface of the placement plate 4 is slidably connected to the inner wall of the outer frame 2. A partition 5 is fixedly installed on the outer surface of the placement plate 4. A sliding hole 51 is opened on the outer surface of the partition 5. A sliding rod 6 is fixedly installed on the inner wall of the sliding hole 51. A first spring 61 is fixedly installed on the outer surface of the sliding rod 6. A total of two sliding holes 51 are provided on the outer surface of the partition 5, and the outer surface of the sliding rod 6 is slidably connected to the inner wall of the sliding hole 51. The top end of the sliding rod 6 is fixedly installed with a clamping plate 62, and one side of the clamping plate 62 is fixedly connected to the top end of the sliding rod 6.

[0022] In this embodiment, the outer frame 2 is provided to provide a protective effect on the electric heating plug to ensure that the electric heating plug does not fall during transportation or handling. By setting the card slot 21 to be snap-fitted with the baffle 3, it is ensured that the baffle 3 will not fall. By setting the baffle 3, it is ensured that the electric heating plug placed inside the outer frame 2 will not fall. By setting the pull rod 31, it is convenient for the staff to remove the baffle 3 and open the placement box 1. By setting the placement plate 4 for placing the electric heating plug. By setting the partition 5 to provide a good installation environment for other components and limit the electric heating plug. By setting the sliding hole 51 to be slidably connected to the sliding rod 6, it is ensured that the sliding rod 6 can move normally. By setting the first spring 61 to drive the sliding rod 6 to displace. Since the sliding rod 6 is fixedly connected to the clamping plate 62, when the sliding rod 6 moves, the clamping plate 62 will also move accordingly. By setting the clamping plate 62 to fix the electric heating plug, it is ensured that there will be no shaking during transportation or handling, and the electric heating plug will not be damaged.

[0023] Embodiment 2

[0024] AsFigures 3 - 4 As shown in the figure, a sliding groove 7 is fixedly installed on the inner wall of the outer frame 2. A sliding rod 71 is fixedly installed on the inner wall of the sliding groove 7. The outer surface of the sliding rod 71 is slidably connected to the inner wall of the sliding groove 7. A second spring 72 is fixedly installed on the outer surface of the sliding rod 71. One end of the second spring 72 is fixedly connected to the outer surface of the sliding rod 71. A blocking piece 73 is fixedly installed at the bottom end of the sliding rod 71. The bottom end of the sliding rod 71 is fixedly connected to one side of the blocking piece 73. The outer surface of the blocking piece 73 is slidably connected to the inner wall of the sliding groove 7.

[0025] In this embodiment, by setting the sliding groove 7, a working environment is provided for the sliding rod 71 to ensure that the sliding rod 71 can move normally. By setting the second spring 72 fixedly connected to the outer surface of the sliding rod 71, it is ensured that the second spring 72 can drive the sliding rod 71 to displace, thereby providing a buffering effect on the placing plate 4 and ensuring that the glow plug will not be damaged. By setting the second spring 72, the buffering work can be carried out normally. By setting the blocking piece 73 fixedly connected to the sliding rod 71, it is ensured that the sliding rod 71 will not fall off from the inside of the sliding groove 7 and ensure the normal progress of the buffering work.

[0026] Working principle:

[0027] As Figures 1 - 4 shown, when the staff uses the placing box 1 to transport the glow plug to prevent breakage, first, the staff places the glow plug inside the two partition plates 5 so that the glow plug is in contact with the placing plate 4. Then, the first spring 61 drives the sliding rod 6 to move. Since the sliding rod 6 is slidably connected to the sliding hole 51, the sliding rod 6 can move normally. And since the sliding rod 6 is fixedly connected to the clamping plate 62, the clamping plate 62 will also move when the sliding rod 6 moves, thereby fixing the glow plug. After the glow plug is fixed, the staff closes the baffle 3 from the inside of the clamping groove 21 to ensure that the glow plug will not fall out of the inside of the outer frame 2. If there is a bump during transportation, the sliding rod 71 will move downward inside the sliding groove 7, compress the second spring 72, and since the second spring 72 is fixedly connected to the sliding rod 71, when the second spring 72 rebounds, it will drive the sliding rod 71 to reset, thereby providing a buffering effect.

[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
