[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1, reference Figure 1-Figure 2, which is the first embodiment of the utility model, provides a cutting device, which includes:

[0031] The support unit 100 includes a base 101 and a housing 102 disposed on the base 101 ; the base 101 is used to fix and support the driving assembly 203 and the cutting assembly 302 .

[0032] The driving unit 200 includes an articulated seat 201 disposed on the base 101, a fixed axis 202 disposed on the articulated seat 201, and a driving assembly 203 disposed on the fixed axis 202; and,

[0033] The cutting unit 300 includes a block 301 disposed on the housing 102, a cutting assembly 302 disposed on the block 301, and a positioning groove 303 disposed on the housing 102. The block 301 places the tooth plate 302a to fall off from the base 101, and the driving assembly 203 is used to drive the cutting assembly 302 to operate, so as to cut the insulation layer of cables of different sizes.

[0034] The driving assembly 203 includes a handle 202a rotatably mounted on the fixed shaft 1 202, a hinge seat 202b mounted on the handle 202a, and a fixed shaft 202c mounted on the hinge seat 202b. The hinge seat 202b and the fixed shaft 202c are used to mount the connecting rod 202d on the handle 202a, and gripping the handle 202a drives the movement of the connecting rod 202d.

[0035] The driving assembly 203 further includes a connecting rod 202d rotatably disposed on the second fixed axis 202c, a third fixed axis 202f disposed on the connecting rod 202d, a connecting seat 202e disposed on the third fixed axis 202f, and a return spring 202g disposed on the connecting seat 202e. The connecting seat 202e and the third fixed axis 202f are used to connect the connecting rod 202d and the tooth plate 302a in the cutting assembly 302, and the movement of the connecting rod 202d drives the tooth plate 302a to move in the base 101.

[0036] During use, the operator places the cable that needs to be repaired between the four cutting components 302 through the positioning ring 207. The diameter of the positioning ring 207 is much larger than the diameter of the cable, and the distance between the two cutting components 302 opposite to the X-axis and the Y-axis is much larger than the diameter of the cable. This ensures that the cutting component 302 can adapt to cables of different diameters, increases the adaptability of the cutting tool to different cable sizes, and cuts the insulation layer on the surface of the cable through the operation of the driving component 203.

[0037] Specifically, when the staff passes the cable through the positioning ring 207 to position the cable between the cutting components 302, the staff holds the gripping rod 202a by hand, and the fixed axis 1 202 and the hinge seat 1 201 at one end of the gripping rod 202a are rotated and fixed on the base 101. By using the lever principle, with the fixed axis 1 202 as the fulcrum, the staff holds the gripping rod 202a, and the connecting rod 202d between the two gripping rods 202a is driven, and the angle between the two connecting rods 202d begins to decrease. The decrease in the angle of the connecting rod 202d pushes the The toothed plate 302a is moved along the base 101 and the positioning ring 207. The movement of the toothed plate 302a drives the cutting assembly 302, so that the cutting assembly 302 is aligned with and contacts the surface of the cable, thereby cutting the surface of the cable. After the cutting is completed, the operator removes his hand from the grip 202a. Under the action of the reset spring 202g, the grip 202a and the connecting rod 202d return to a normal angle. Finally, the operator removes the cut cable from the positioning ring 207.

[0038] Due to the design of the spacing between the positioning ring 207 and the cutting assembly 302, it can adapt to cables of different calibers, increasing the versatility and flexibility of the leakage repair device. The fast cutting action and simple operation process improve work efficiency and reduce the time required for repairing or replacing cables.

[0039] Example 2, reference Figure 1-Figure 3 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: a rotating shaft 204 is provided on the housing 102, and a circular gear 205 is provided on the rotating shaft 204, and the circular gears 205 are arranged in a linear array inside the housing 102. The rotating shaft 204 is used to fix and support the rotation of the circular gear 205, and both ends of the rotating shaft 204 are fixed on the inner surface of the housing 102, and the circular gear 205 directly below the tooth plate 302a connected to the connecting seat 202e is used to drive the rotation of the gear ring 206.

[0040] Compared with the embodiment 1, a gear ring 206 is further provided on the circular gear 205, one side of the gear ring 206 is provided on the base 101, and a positioning ring 207 is provided on one side of the circular gear 205. After the gear ring 206 is driven to rotate by the circular gear 205 directly below the gear plate 302a connected to the connecting seat 202e, it is used to drive the rotation of the other three circular gears 205. The rotation of the other three circular gears 205 can drive the gear plate 302a with a block 301 at one end to move in the base 101 and the positioning ring 207.

[0041] During use, when the operators start working, they first hold the rod 202a tightly and operate it. This action triggers the first step of the mechanical linkage. As the grip 202a moves, the connecting rod 202d moves accordingly, and the angle between the two connecting rods 202d decreases, thereby pushing the toothed plate 302a connected to them to move along the positioning groove 303 on the base 101 and the positioning ring 207. The movement of the toothed plate 302a drives the circular gear 205 directly below to rotate, and this rotation triggers the rotation of the toothed ring 206 on the base 101. The rotation of the toothed ring 206 triggers a chain reaction, causing the other three circular gears 205 to start rotating, thereby driving the remaining three toothed plates 302a with a block 301 at one end and the toothed plates 302a connected to the connecting seat 202e at one end to move the same distance in the positioning ring 207 and the base 101, so that the cutting knife 302d and the positioning roller 302i on the cutting assembly 302 act on the surface of the cable at the same time to cut the insulating layer on the surface of the cable.

[0042] Through mechanical linkage, the entire cutting process only requires the operator to control by simply gripping the grip 202a, which simplifies the cable cutting operation process and avoids the operator from frequently changing cutting tools. The operator can quickly complete the cable cutting work and improve the efficiency of cutting the cable surface insulation layer.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 1-Figure 4 , which is the third embodiment of the utility model, is different from the second embodiment in that the cutting assembly 302 includes a tooth plate 302a disposed on the blocking block 301, a mounting plate 302b disposed on the tooth plate 302a, and a support block 302c disposed on the mounting plate 302b. The tooth plate 302a is used to drive the movement of the mounting plate 302b, and the support block 302c is used to fix and support the cutting knife 302d.

[0045] Compared with Example 2, further, the tooth plate 302a is provided with a guide block 304, the tooth plate 302a is provided on the positioning groove 303, the guide block 304 is provided on the positioning groove 303, and the tooth plates 302a are arranged in a linear array on the base 101. The guide block 304 slides in the positioning groove 303 to fix the position of the tooth plate 302a in the positioning groove 303, and the position of the tooth plate 302a is offset during the movement.

[0046] Furthermore, a cutting knife 302d is provided on the support block 302c, the support block 302c is L-shaped, and the cutting knife 302d is cone-shaped. The support block 302c is L-shaped, and the cutting knife 302d is provided at the top of the L-shaped support block 302c, so as to facilitate cutting the surface of the cable.

[0047] Furthermore, a limit plate 302f is provided on the mounting plate 302b, a slide rod 302g is provided on the limit plate 302f, and a positioning spring 302e is provided on the slide rod 302g. The limit plate 302f is used to position the sliding slide rod 302g, and the positioning spring 302e is used to reset the moving slide rod 302g.

[0048] The positioning spring 302e is arranged between the sliding rod 302g and the tooth plate 302a, one end of the positioning spring 302e is arranged on the sliding rod 302g, and the other end of the positioning spring 302e is arranged on the tooth plate 302a. The sliding rod 302g is provided with a support seat 302h, and the support seat 302h is provided with a positioning roller 302i. The length of the positioning roller 302i and the sliding rod 302g in the original state is longer than the horizontal length of the cutting knife 302d on the supporting block 302c, and the positioning roller 302i slides toward the tooth plate 302a through the sliding rod, so that the cutting knife 302d contacts the cable.

[0049] During use, the movement of the tooth plate 302a drives the mounting plate 302b to slide toward the center position of the housing 102, and the slide rod drives the positioning roller 302i to first abut the outside of the cable, so that the cable is positioned by the positioning roller 302i, which is convenient for the cutting knife 302d to cut and strip the insulation layer on the surface of the cable. At this time, under the continuous movement of the tooth plate 302a, the positioning roller 302i slides toward the tooth plate 302a through the slide rod, so that the cutting knife 302d contacts the cable and presses into the insulation layer of the cable, and then the housing 102 is rotated ninety degrees so that the cutting knife 302d cuts the insulation layer of the cable longitudinally, thereby cutting off the insulation layer on the outside of the cable, and pulling out the cut part of the insulation layer from the outside of one end of the cable, so as to facilitate observation of the internal situation of the cable and repair. Through the sliding cooperation of the four sets of tooth plates 302a, cables of different sizes can be cut and repaired without repeated replacement of tools, thereby improving the maintenance efficiency of the cable.

[0050] The remaining structure is the same as that of Example 2.
