[0029] Embodiment 1

[0030] The present utility model provides the following technical solutions: As Figures 1 - 5 shown, a thermally conductive silicone sheet with adhesiveness on both sides includes a thermally conductive silicone sheet body 100. Adhesive layers 101 are connected to both the top and bottom of the thermally conductive silicone sheet body 100. A release paper 102 is connected to the top of the adhesive layer 101. Cutting strips 10001 are connected to both sides of the thermally conductive silicone sheet body 100. A limiting strip 10002 is connected to one side of the cutting strip 10001. A fixing frame 105 is sleeved outside the limiting strip 10002. A fixing rod 10501 is connected to one end of a pair of fixing frames 105. A cutting mechanism 107 is connected to the top of the fixing frame 105. By connecting adhesive layers 101 to both the top and bottom of the thermally conductive silicone sheet body 100, double-sided adhesion of the thermally conductive silicone sheet body 100 is achieved. By connecting a release paper 102 to the top of the adhesive layer 101, protection of the adhesive layer 101 is achieved. By connecting a fixing rod 10501 to one end of a pair of fixing frames 105, support of the fixing frame 105 is achieved, avoiding the situation where the thermally conductive silicone sheet body 100 adheres together.

[0031] Embodiment 2

[0032] Referring to Figures 1 - 5As shown in the figure, the cutting mechanism 107 includes a pressing plate 10701. A cutting knife 10702 is installed on one side of the pressing plate 10701. The cutting knife 10702 is located at the top of the cutting strip 10001. Slide rods 10703 are slidably connected to both ends of the pressing plate 10701. The bottom ends of the slide rods 10703 are fixedly connected to the top end of the fixed frame 105. A spring 10704 is sleeved on the outer side of the slide rod 10703. The top end of the spring 10704 is connected to the bottom end of the pressing plate 10701, and the bottom end of the spring 10704 is connected to the top end of the fixed frame 105. A limit plate 10705 is installed at the top end of the slide rod 10703. By installing a cutting knife 10702 on one side of the pressing plate 10701, pressing the pressing plate 10701 can make the cutting knife 10702 cut the cutting strip 10001, so as to separate the fixed frame 105 from the heat-conducting silicone sheet body 100. By slidably connecting slide rods 10703 to both ends of the pressing plate 10701, the pressing stability of the pressing plate 10701 is improved. By sleeving a spring 10704 on the outer side of the slide rod 10703, the pressing plate 10701 can automatically reset after being pressed. By installing a limit plate 10705 at the top end of the slide rod 10703, the limit of the pressing plate 10701 after reset is realized, and the pressing plate 10701 is prevented from sliding out of the slide rod 10703.

[0033] Embodiment 3

[0034] Referring to Figures 1 - 5 As shown in the figure, a number of limit holes 10003 are opened at the top end of the limit strip 10002. A number of limit posts 106 are installed inside the limit holes 10003. The top and bottom ends of the limit posts 106 are respectively fixedly connected to the inside of the fixed frame 105. A connecting strip 103 is connected to one side of the release paper 102. A pulling belt 104 is connected to one end of the connecting strip 103. By installing a number of limit posts 106 inside the limit holes 10003, the connection firmness between the limit strip 10002 and the fixed frame 105 is improved. By connecting a pulling belt 104 to one end of the connecting strip 103, it is convenient for the user to pull out the release paper 102.

[0035] Specifically, the working principle of the double-sided adhesive thermal conductive silicone sheet: When in use, the release paper 102 at the bottom of the thermal conductive silicone sheet body 100 is torn off through the pulling belt 104, so that the thermal conductive silicone sheet body 100 is pasted on the device with the equipment. By pressing the pressing plate 10701, the cutting knife 10702 cuts the cutting strip 10001. Then, the release paper 102 at the top of the thermal conductive silicone sheet body 100 can be torn off through the pulling belt 104. Since the top and bottom ends of the thermal conductive silicone sheet body 100 are both connected with the adhesive layer 101, the double-sided pasting of the thermal conductive silicone sheet body 100 is realized. Since the top end of the adhesive layer 101 is connected with the release paper 102, the protection of the adhesive layer 101 is realized. Since one end of a pair of fixed frames 105 is connected with the fixed rod 10501, the support of the fixed frame 105 is realized, avoiding the situation that the thermal conductive silicone sheet body 100 is bonded together. Since the cutting knife 10702 is installed on one side of the pressing plate 10701, pressing the pressing plate 10701 can make the cutting knife 10702 cut the cutting strip 10001, thereby realizing the separation of the fixed frame 105 and the thermal conductive silicone sheet body 100. Since both ends of the pressing plate 10701 are slidably connected with the sliding rods 10703, the pressing stability of the pressing plate 10701 is improved. Since the outer side of the sliding rod 10703 is sleeved with the spring 10704, the automatic reset of the pressing plate 10701 after pressing is realized. Since the limiting plate 10705 is installed at the top end of the sliding rod 10703, the limiting of the pressing plate 10701 after reset is realized, avoiding the pressing plate 10701 from sliding out of the sliding rod 10703. Since a plurality of limiting columns 106 are installed inside the limiting holes 10003, the connection firmness between the limiting strip 10002 and the fixed frame 105 is improved. Since one end of the connecting strip 103 is connected with the pulling belt 104, it is convenient for the user to pull out the release paper 102. The utility model can effectively prevent the thermal conductive silicone sheets from being bonded together during pasting, improve the use convenience of the user, and has high practical value.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
