[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 In the present embodiment, a high temperature resistant composite insulating paper comprises a fixing tube 1, which is cylindrical, and an insulating paper body 2 is provided with a mounting hole adapted to the fixing tube 1. By setting the mounting hole, the insulating paper body 2 can be installed more conveniently, which not only saves the installation time, but also can adapt to insulating paper bodies 2 of different sizes. The outer surface of the fixing tube 1 is fixed with the insulating paper body 2, and the front of the stabilizing block 501 is provided with a positioning hole adapted to the insulating paper body 2. When the insulating paper body 2 is cut, the insulating paper body 2 is restricted by the positioning hole to avoid the sliding of the insulating paper body 2 during the cutting process, resulting in the cut insulating paper body 2 not meeting the required length. The outer surface of the fixing tube 1 The left and right sides of the surface are rotatably connected with a rotating component, and a cutting component 5 for cutting the insulating paper body 2 is fixed on the top of the rotating component. The rotating component can drive the cutting component 5 to rotate as a whole. The rotating component is composed of two rotating blocks 3 and two connecting rods 4. The two rotating blocks 3 are both mounted on the outer surface of the fixed cylinder 1 and distributed on the left and right. The cutting component 5 is driven to rotate as a whole by the rotating block 3, which can improve the practicality of the cutting component 5. It can be cut at different angles and is more convenient to use. The connecting rod 4 is fixed between the rotating block 3 and the stabilizing block 501. The connecting rod 4 plays the role of connecting the cutting component 5 and has a certain stability, so that the cutting process of the cutting component 5 is smoother.

[0022] In this embodiment, after the cutting assembly 5 is driven by the rotating block 3 to move as a whole to the incision of the insulating paper body 2, the insulating paper body 2 is cut by the cutting assembly 5, thereby achieving the purpose of facilitating cutting and saving time and effort.

[0023] See also Figure 3In order to facilitate cutting, the cutting assembly 5 in this embodiment includes a stabilizing block 501 fixed to the top of the rotating assembly. Two return springs 502 are fixed to the inner bottom wall of the stabilizing block 501 and both penetrate the outer side of the stabilizing block 501. The return spring 502 not only limits the movement of the pressing plate 504, but also drives the pressing plate 504 back to the origin after the pressing plate 504 is pressed down for cutting, so as to facilitate cutting again. There is no need to manually pull the pressing plate 504 back to the origin, which is more time-saving and labor-saving. The movable hole is adapted to the return spring 502, and the movable hole can limit the moving direction of the return spring 502 so that it can only rise or fall vertically, thereby ensuring the stability of the cutting assembly 5 during overall operation. The inner cavities of the two return springs 502 are fixed with connecting rods 503, which are connected to the pressure plate 504 through the connecting rods 503, so that the pressure plate 504 and the return spring 502 restrict each other to improve stability. The pressure plate 504 can only be raised and lowered vertically to ensure the flatness of the incision of the insulating paper body 2, and a downward pressing part is fixed on the top of the connecting rod 503 and the return spring 502.

[0024] It should be noted that the pressing part is composed of a pressing plate 504 and a cutter 505. The pressing plate 504 is fixed to the top of the connecting rod 503 and the return spring 502. The cutter 505 is fixed to the bottom of the pressing plate 504 and penetrates into the inner cavity of the stabilizing block 501. A guide hole for the movement of the cutter 505 is provided on the stabilizing block 501. The guide hole not only limits the moving direction of the cutter 505 so that the cutter 505 can only move up and down, but also has a certain degree of safety, avoiding injuries caused by contact between fingers and the cutter 505 when pulling the insulating paper body 2, thereby playing a protective role.

[0025] In this embodiment, by applying downward pressure to the pressing plate 504, the cutter 505 is driven to move downward, and finally the cutter 505 contacts the inner bottom wall of the stabilizing block 501 to cut the insulating paper body 2, thereby facilitating cutting and saving time and effort.

[0026] The working principle of the above embodiment is:

[0027] When it is necessary to cut the insulating paper body 2, first, the insulating paper body 2 is passed through the positioning hole of the stabilizing block 501, and the insulating paper body 2 is pulled to the required length and then stopped, and then the pressing plate 504 is pressed downward. The pressure on the pressing plate 504 will drive the cutter 505 to move downward at the same time. Since the pressing plate 504 is restricted by the connecting rod 503, the pressing plate 504 can only move vertically up and down. At this time, the cutter 505 moves downward until it contacts the inner bottom wall of the stabilizing block 501 to complete the cutting of the insulating paper body 2. Then, the pressing plate 504 is released. After the pressure is lost, the rebound force of the two return springs 502 pushes the connecting rod 503 and the pressing plate 504 back to the origin, and finally drives the cutter 505 to move upward for easy use next time, thereby achieving the purpose of easy cutting and saving time and effort.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
