The second mounting shell is provided on the back of the first mounting shell, and the wire body is passed through the wire holes of the first mounting shell and the second mounting shell. The blade device is installed inside the first mounting shell, and the transmission mechanism is installed inside the second mounting shell. By installing the blade device and the transmission mechanism, wire bodies of different sizes can be firmly clamped, and wire bodies of different sizes can be stripped, thereby improving the efficiency and practicality of the stripping device; the utility model is also suitable for the field of power construction.

[0004] However, when stripping a wire, the aforementioned device activates a drive motor to rotate a bidirectional lead screw within the lead screw mounting slot. The lead screw surface contacts the interior of a moving block, controlling the blade bodies to move toward or away from each other along the blade mounting slot. The blade bodies move toward each other to strip the wire body, and after stripping is complete, the blade bodies move away from each other. Because the blade bodies can only cut the upper and lower surfaces of the wire, the insulation layer on the side of a cylindrical wire may not be completely cut through, resulting in poor stripping results. This may leave unstripped insulation, affecting the quality of subsequent electrical connections. Utility Model Content

DETAILED DESCRIPTION

[0026] Please refer to Figure 1-Figure 5 A wire stripping device, including wire main body 1 and the first installation shell 2 and the second installation shell 3 of being set on its surface left and right sides:

[0027] Furthermore, the first mounting shell 2 includes a first shell 201 sleeved on the left side of the surface of the wire body 1, a threading hole is opened in the center of the first shell 201, and four cutting knives 202 are arranged in a circular array inside the threading hole. The four cutting knives 202 are fixedly connected to the surface of the first shell 201 away from the axis. The four threaded sleeves 203 extend from one end of the cutting knife 202 to the inside of the first shell 201 and are slidably connected thereto. The movement trajectory of the four threaded sleeves 203 is to slide from the axis of the first shell 201 to the circumference of the first shell 201;

[0028] A threading hole is provided in the center of the first shell 201, and four cutting knives 202 are provided inside the threading hole. The cutting knives 202 are arranged in a circular array, and each cutting knife 202 is fixed by a threaded sleeve 203. The threaded sleeve 203 can slide inside the first shell 201, and the movement trajectory is from the axis to the circumference. The cutting knife 202 moves outward from the axis of the first shell 201 through the sliding of the threaded sleeve 203, gradually approaching the surface of the wire body 1, thereby achieving cutting of the wire insulation layer. Since the cutting knives 202 are arranged in a circular array, the insulation layer of the wire can be cut from multiple angles at the same time, ensuring the uniformity and integrity of the cutting.

[0029] Furthermore, the second mounting shell 3 includes a second shell 301 sleeved on the right side of the surface of the wire body 1. A threading hole is opened in the center of the second shell 301. Arc-shaped clamping plates 302 are provided on the upper and lower sides of the threading hole respectively. The inner walls of the two arc-shaped clamping plates 302 are in contact with the surface of the wire body 1. The two arc-shaped clamping plates 302 are fixedly connected to the side away from each other with a connecting rod 303. The two connecting rods 303 extend from one end away from each other into the interior of the second shell 301 and are slidably connected thereto.

[0030] Furthermore, a plurality of electric push rods 4 are fixedly connected to a side of the second housing 301 close to the first housing 201 , and the telescopic ends of the plurality of electric push rods 4 are fixedly connected to a side of the first housing 201 .

[0031] Multiple electric push rods 4 are fixed on one side of the second shell 301 close to the first shell 201. The telescopic ends of the electric push rods 4 are fixedly connected to the first shell 201. The relative positions of the first mounting shell 2 and the second mounting shell 3 can be controlled by the telescopic action of the electric push rods 4.

[0032] Furthermore, the axes of the wire body 1, the first shell 201 and the second shell 301 coincide with each other, the threading holes are located on the same horizontal line, and the first shell 201 and the second shell 301 are both made of stainless steel.

[0033] The wire body 1 is a wire that needs to be stripped, and its axis coincides with the axis of the first shell 201 and the second shell 301 to ensure that the wire is placed in the center of the device. The first shell 201 is made of stainless steel and has good corrosion resistance and mechanical strength. The second shell 301 is also made of stainless steel, which is consistent with the material of the first shell 201, ensuring the stability and durability of the overall structure.

[0034] Furthermore, the inner walls of the four threaded sleeves 203 are threadedly connected to threaded rods 204, and the four threaded rods 204 are arranged in a circular array inside the first shell 201 and are rotatably connected to the first shell 201. One side of the four threaded sleeves 203 is slidably connected to a guide rod 213, and the four guide rods 213 are fixedly arranged in a circular array inside the first shell 201.

[0035] Furthermore, bevel gears 205 are fixedly sleeved on the surfaces of the four threaded rods 204, and the four bevel gears 205 are meshedly connected to the same bevel gear ring 206 on one side. The bevel gear ring 206 is connected to a plurality of annular blocks 208 in a circular array on the side away from the bevel gear 205, and an annular groove 209 is opened on one side of the inner wall of the first shell 201, and the plurality of annular blocks 208 and the annular groove 209 are slidably connected.

[0036] Furthermore, a number one gear 207 is fixedly sleeved on the circumferential surface of the bevel gear ring 206, and a number two gear 210 is meshedly connected to the top of the number one gear 207. A slot 211 is provided on the top of the first shell 201. The number two gear 210 extends to the outside of the first shell 201 and is rotatably connected to the slot 211. A first motor 212 is fixedly connected to the top of the first shell 201, and the output shaft of the first motor 212 is fixedly connected to the inner wall of the number two gear 210.

[0037] After the first motor 212 is started, its output shaft begins to rotate, driving the second gear 210. The second gear 210 meshes with the first gear 207, causing the first gear 207 to also rotate. The first gear 207 is fixedly mounted on the bevel gear ring 206, rotating along with the first gear 207. The bevel gear ring 206 meshes with the four bevel gears 205, causing all four bevel gears 205 to rotate simultaneously. Each bevel gear 205 is fixedly mounted on a threaded rod 204, causing the four threaded rods 204 to rotate synchronously. As the four threaded rods 204 rotate, the threaded connections push the four threaded sleeves 203 along the guide rod 213. The threaded sleeve 203 moves in a circular motion from the axis of the first housing 201, driving the cutting blades 202 gradually closer to the surface of the wire body 1. The four cutting blades 202 move from the center of the wire body 1 outward, gradually approaching the surface of the wire and beginning to cut the wire's insulation. Because the four cutting blades 202 are arranged in a circular array, they can simultaneously cut the wire's insulation from multiple angles, ensuring uniform and complete cutting. When the cutting blades 202 complete their cutting, the first motor 212 stops, and the threaded rod 204 rotates in the opposite direction, driving the threaded sleeve 203 and cutting blades 202 away from the wire body 1. The insulation of the wire body 1 is completely cut, allowing for easy stripping.

[0038] Furthermore, opposite ends of the two connecting rods 303 are fixedly connected to movable plates 304 . The two movable plates 304 are correspondingly arranged at upper and lower positions inside the second shell 301 and are slidably connected to the second shell 301 .

[0039] Furthermore, one side of the inner wall of the two movable plates 304 is threadedly connected to the same bidirectional screw rod 305, and the bidirectional screw rod 305 is rotatably set on one side of the inside of the second shell 301. The other side of the inner wall of the two movable plates 304 is slidably connected to a limiting rod 309, and the limiting rod 309 is fixedly set on the other side of the inside of the second shell 301.

[0040] Furthermore, a worm gear 306 is fixedly sleeved on the central surface of the bidirectional screw rod 305, and a worm 307 is meshedly connected to one side of the worm gear 306. A second motor 308 is fixedly connected to one side of the outer wall of the second shell 301, and the output shaft of the second motor 308 extends to the interior of the second shell 301 and is fixedly connected to one end of the worm 307.

[0041] After the second motor 308 is started, its output shaft rotates, driving the worm 307 to rotate. The rotation of the worm 307 drives the worm wheel 306 to rotate through the meshing relationship. The rotation of the worm wheel 306 drives the bidirectional screw 305 to rotate. The rotation of the bidirectional screw 305 pushes the two movable plates 304 to slide along the limit rod 309 through the threaded connection. The two movable plates 304 slide along the limit rod 309, driving the two arc-shaped clamping plates 302 to move closer to or away from each other, thereby clamping or releasing the wire body 1. When the cutting is completed, the second motor 308 rotates in the opposite direction, and the bidirectional screw 305 rotates in the opposite direction, driving the two movable plates 304 to slide along the limit rod 309, so that the two arc-shaped clamping plates 302 move away from each other, releasing the wire body 1.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
