[0044] As Figure 1-2 shown, a wire stripping and cutting device provided by an embodiment of the present invention includes: a clamping assembly 1, a wire cutting assembly 2, a second driving member 3, and a control switch (not shown in the figure);

[0045] The clamping assembly 1 includes two oppositely arranged clamping members 11, and a clamping opening for accommodating a wire 5 is defined between the two clamping members 11;

[0046] The wire cutting assembly 2 includes a first driving member 22 and two oppositely arranged wire cutting members 21. A wire cutting opening for placing the wire 5 is defined between the two wire cutting members 21. The wire cutting opening and the clamping opening are parallel in the first direction X. The first driving member 22 is connected to the two wire cutting members 21, and the first driving member 22 is used to drive the two wire cutting members 21 to open or close;

[0047] The second driving member 3 is connected to the clamping assembly 1. The second driving member 3 is used to drive the two clamping members 11 to open or close, and the first driving member 22 is mounted on the second driving member 3;

[0048] The control switch is electrically connected to the first driving member 22. The control switch is used to switch between a first gear and a second gear. When the control switch switches to the first gear, the first driving member 22 drives the two wire cutting members 21 to open. When the control switch switches to the second gear, the first driving member 22 drives the two wire cutting members 21 to close.

[0049] It should be noted that before cutting the wire, the operator holds the anti - detachment wire cutter, operates the second driving member 3 to drive the two clamping members 11 of the clamping assembly 1 to open, and switches the control switch to the first gear. The control switch controls the first driving member 22 to drive the two wire - cutting members 21 of the wire - cutting assembly 2 to open, and puts the wire 5 into the clamping opening and the wire - cutting opening at the same time.

[0050] After that, the second driving member 3 drives the two clamping members 11 to close, clamping the wire 5. Then the control switch is switched to the second gear, and the control switch controls the first driving member 22 to drive the two wire - cutting members 21 to close, cutting the wire 5. During the wire - cutting process, the two clamping members 11 can be kept closed to clamp the wire 5 all the time. Therefore, after the wire 5 is cut, the situation that the movable end of the wire 5 swings or even drops can be effectively avoided.

[0051] The second driving member 3 is connected to the clamping assembly 1, the first driving member 22 is installed on the second driving member 3, and the first driving member 22 is connected to the two wire - cutting members 21, forming an integral anti - detachment wire cutter. The structure of the anti - detachment wire cutter of the present application is simple and the operation is more convenient.

[0052] The clamping member 11 is preferably a clamping plate, and the wire - cutting member 21 is preferably a cutting head.

[0053] The operator can switch the control switch between the first gear and the second gear by pressing the control switch, or switch the control switch between the first gear and the second gear by timing.

[0054] In a more specific embodiment, the second driving member 3 is used to adjust the degree of opening or closing of the two clamping members 11. Therefore, the second driving member 3 can adjust the size of the clamping opening to adapt to clamping wires 5 with different diameters, and can also adjust the clamping force on the wire 5 to avoid damaging the structure of the wire 5 due to excessive clamping force.

[0055] As Figure 1-4 shown, in a more specific embodiment, the clamping assembly 1 further includes: a mounting seat 12, a plurality of first hinge arms 13 and a plurality of second hinge arms 15;

[0056] The mounting seat 12 includes a main body 121 and two fixing ears 122, and the two fixing ears 122 are respectively connected to both sides of the main body 121 in the first direction X;

[0057] The first ends of two adjacent first hinge arms 13 are connected by a first hinge shaft 14;

[0058] The middle parts of two adjacent second articulated arms 15 are arranged in a crosswise manner and are connected by a second articulated shaft 16. The second articulated shaft 16 is parallel to the first articulated shaft 14. The second articulated shaft 16 is installed between two fixed ears 122. The first end of the second articulated arm 15 is articulated to the second end of the corresponding first articulated arm 13, and the second end of the second articulated arm 15 is connected to the corresponding clamping member 11;

[0059] The main body 121, the first articulated arm 13, the second articulated arm 15, and the clamping member 11 are arranged in sequence along the second direction Y;

[0060] The second driving member 3 is connected to the mounting base 12. The second driving member 3 is used to drive two adjacent first articulated arms 13 to open or close;

[0061] Wherein, the first direction X and the second direction Y are perpendicular to each other.

[0062] It should be noted that before wire cutting, the second driving member 3 drives two adjacent first articulated arms 13 to open. Since the middle parts of two adjacent second articulated arms 15 are arranged in a crosswise manner and are connected by a second articulated shaft 16, the second articulated shaft 16 is installed between two fixed ears 122, the second articulated shaft 16 is stationary relative to the two fixed ears 122, and the second articulated arm 15 is also articulated to the first articulated arm 13. Therefore, two adjacent first articulated arms 13 drive the first ends of the corresponding two second articulated arms 15 to open, and the second ends of the corresponding two second articulated arms 15 also open, and the two clamping members 11 move away from each other, opening the two clamping members 11.

[0063] After placing the wire 5 into the clamping opening, the second driving member 3 drives two adjacent first articulated arms 13 to close, thereby driving the first ends of the corresponding second articulated arms 15 to close, and the second ends of the corresponding second articulated arms 15 also close, and the two clamping members 11 move towards each other, closing the two clamping members 11.

[0064] In a more specific embodiment, the second driving member 3 is used to adjust the degree of opening or closing of two adjacent first articulated arms 13. Therefore, the second driving member 3 can adjust the size of the clamping opening to adapt to clamping wires 5 with different diameters, and can also adjust the clamping force of the wire 5 to avoid damaging the structure of the wire 5 due to excessive clamping force.

[0065] The first end of the second articulated arm 15 being articulated to the second end of the corresponding first articulated arm 13 specifically means that: the second ends of two adjacent first articulated arms 13 and the first ends of two adjacent second articulated arms 15 are connected by different articulated shafts.

[0066] The second end of the second articulated arm 15 being connected to the corresponding clamping member 11 specifically means that: the first ends of two adjacent articulated arms are respectively connected to two clamping members 11.

[0067] Such as Figure 1-4As shown, in a more specific embodiment, a threaded hole 1211 penetrating along the second direction Y is formed in the main body 121;

[0068] The second driving member 3 includes: a tube body 31, a movable block 32, a threaded rod 33, and a handle 34;

[0069] The tube body 31 extends along the second direction Y, the main body 121 is installed at the first end of the tube body 31, and the first driving member 22 is installed on the tube body 31;

[0070] The movable block 32 includes a mounting portion 321 and two sliding portions 322. The two sliding portions 322 are respectively connected to both sides of the mounting portion 321 in the first direction X, and the first hinge shaft 14 is installed between the two sliding portions 322;

[0071] The threaded rod 33 is disposed inside the tube body 31, and the first end of the threaded rod 33 passes through the threaded hole 1211 to connect the movable block 32;

[0072] The handle 34 is disposed near the second end of the tube body 31. The handle 34 is connected to the threaded rod 33, and a control switch (not shown in the figure) is installed on the handle 34.

[0073] It should be noted that before wire cutting, the control switch on the handle is switched to the first gear, and the control switch sends a corresponding signal to the first driving member 22, and the first driving member 22 drives the two wire cutting members 21 to open. The operator can switch the gear of the control switch by pressing the control switch or by timing.

[0074] The operator holds the tube body 31 with one hand and rotates the handle 34 with the other hand. The handle 34 drives the threaded rod 33 to rotate. The handle 34 can adjust the number of turns of the threaded rod 33 to move the threaded rod 33 along the second direction Y relative to the main body 121 of the mounting seat 12 by a corresponding distance. The threaded rod 33 drives the connected movable block 32 to move synchronously by a corresponding distance. Since the first hinge shaft 14 is installed between the two sliding portions 322 of the movable block 32, it can drive the plurality of first hinge arms 13 to open by a corresponding angle, and further drive the second hinge arms 15 to open by a corresponding angle, and the two clamping members 11 move away from each other by a corresponding distance to adjust the degree of opening of the two clamping members 11.

[0075] After placing the wire 5 into the wire cutting opening and the clamping opening, rotate the handle 34 in the reverse direction. The handle 34 drives the threaded rod 33 to rotate in the reverse direction, and the number of turns of the threaded rod 33 can be adjusted, so that the threaded rod 33 moves a corresponding distance in the reverse direction of the second direction Y relative to the main body 121 of the mounting base 12. The threaded rod 33 drives the connected movable block 32 to move the corresponding distance synchronously, and multiple first hinge arms 13 close by the corresponding angle. Further, multiple second hinge arms 15 also close by the corresponding angle, and the two clamping members 11 move towards each other by the corresponding distance, adjusting the degree of closing of the two clamping members 11 to clamp the wire 5, adapting to clamping wires 5 of different diameters, and also being able to adjust the clamping force of the wire 5 to avoid damaging the structure of the wire 5 due to excessive clamping force.

[0076] One end of the handle 34 away from the threaded rod 33 is a hexagonal nut structure, and the staff can use an ordinary wrench or an electric wrench to act on the hexagonal nut structure for screwing, so as to drive the handle 34 to rotate.

[0077] Alternatively, the handle 34 is an electric rotating device and can rotate by itself.

[0078] The first driving member 22 of the wire cutting assembly 2 is installed on the outer side of the tube body 31 and will not be affected by the movement of the threaded rod 33 inside the tube body 31.

[0079] When the two clamping members 11 are closed and the clamping members 11 clamp the wire 5, switch the control switch to the second gear. The control switch sends a corresponding signal to the first driving member 22, and the first driving member 22 drives the two wire cutting members 21 to close, cutting the wire 5.

[0080] In another more specific embodiment, the second driving member 3 further includes: a sensor. The sensor is electrically connected to the control switch. The sensor is installed on the clamping member 11 and is used to detect whether the clamping member 11 clamps the wire 5. When the sensor detects that the clamping member 11 clamps the wire 5, the sensor sends a signal to the control switch. The control switch switches to the second gear, and the control switch sends a corresponding signal to the first driving member 22, and the first driving member 22 drives the two wire cutting members 21 to close.

[0081] The sensor is preferably a pressure sensor. The pressure sensor is arranged on the opposite surfaces of the clamping member 11. When the pressure sensor senses an increase in pressure (the clamping member 11 and the wire 5 contact and squeeze the pressure sensor), it proves that the clamping member 11 has clamped the wire 5.

[0082] In an even more specific embodiment, the second driving member 3 includes a fixing member and a plurality of clamping claws. The fixing member is connected to the mounting base 12, and the plurality of clamping claws are connected to the fixing member. The plurality of clamping claws respectively clamp a plurality of first hinge arms 13 one by one, open or close two adjacent first hinge arms 13, and can adjust the degree of opening or closing of two adjacent first hinge arms 13. The first driving member 22 of the wire cutting assembly 2 is mounted on the fixing member.

[0083] As Figure 1-4 shown, in an even more specific embodiment, the fixing ear 122 is provided with sliding holes 1221 extending along the second direction Y, and the two sliding portions 322 are respectively snapped into the two sliding holes 1221.

[0084] It should be noted that the fixing ear 122 is provided with sliding holes 1221 extending along the second direction Y, and the two sliding portions 322 are respectively snapped into the two sliding holes 1221. Therefore, the movable block 32 can move relative to the mounting base 12, and the sliding holes 1221 limit the moving path of the sliding portions 322. Therefore, when the threaded rod 33 pushes the movable block 32 to move, it is smoother.

[0085] Preferably, the fixing ear 122 extends along the second direction Y, and the sliding portion 322 extends along the second direction Y.

[0086] As Figure 1-2 shown, in an even more specific embodiment, the second driving member 3 further includes: a connecting rod 35;

[0087] The connecting rod 35 is disposed in the pipe body 31. The first end of the connecting rod 35 is connected to the handle 34, and the second end of the connecting rod 35 is connected to the second end of the threaded rod 33;

[0088] The handle 34 is used to control the rotation of the connecting rod 35.

[0089] It should be noted that when wire cutting work needs to be performed on a wire 5 at a relatively long distance, the length of the pipe body 31 needs to be set longer so that the wire 5 can be placed into the clamping opening and the wire cutting opening. The process of making the thread on the threaded rod 33 is relatively complex. Therefore, the length of the threaded rod 33 can remain unchanged, and the length of the threaded rod 33 is adapted to the length of the sliding holes 1221.

[0090] A longer connecting rod 35 is provided. The connecting rod 35 does not need to be made with a thread. The first end of the connecting rod 35 is connected to the handle 34, and the second end of the connecting rod 35 is connected to the second end of the threaded rod 33. The handle 34 controls the rotation of the connecting rod 35, thereby controlling the rotation of the threaded rod 33.

[0091] As Figure 1 shown, in an even more specific embodiment, it further includes: a fixture 4;

[0092] The fixture 4 includes two first semi-circular rings 41 and two second semi-circular rings 42. The first ends of the two first semi-circular rings 41 are connected, and the first ends of the two second semi-circular rings 42 are connected. The second end of the first semi-circular ring 41 is connected to the corresponding second end of the second semi-circular ring 42. A first fixing opening for accommodating the pipe body 31 is formed between the two first semi-circular rings 41, and a second fixing opening for accommodating the first driving member 22 is formed between the two second semi-circular rings 42.

[0093] It should be noted that the fixture 4 can install the first driving member 22 on the outer side of the pipe body 31, improving the stability of the installation of the first driving member 22 on the pipe body 31.

[0094] In another more specific embodiment, there are multiple fixtures 4, and the multiple fixtures 4 are arranged in sequence along the second direction Y. Using multiple fixtures 4 to clamp and fix the pipe body 31 and the first driving member 22 can improve the stability of the installation between the two.

[0095] As Figure 1 shown, in a more specific embodiment, a first extension portion 43 is provided on the side of the first semi-circular ring 41 away from the second semi-circular ring 42, and the two first extension portions 43 are connected by bolts. A second extension portion 44 is provided on the side of the second semi-circular ring 42 away from the first semi-circular ring 41, and the two second extension portions 44 are connected by bolts. A third extension portion 45 is provided on the side where the first semi-circular ring 41 and the second semi-circular ring 42 are connected, and the two third extension portions 45 are connected by bolts.

[0096] It should be noted that the first semi-circular ring 41 is connected to the corresponding second semi-circular ring 42 through the third extension portion 45. A first extension portion 43 is provided on the side of the first semi-circular ring 41 away from the second semi-circular ring 42, and a second extension portion 44 is provided on the side of the second semi-circular ring 42 away from the first semi-circular ring 41. That is, the first extension portion 43, the first semi-circular ring 41, the third extension portion 45, the second semi-circular ring 42, and the second extension portion 44 are connected in sequence to form a whole. The two first extension portions 43 and the two second extension portions 44 are connected by bolts, improving the stability of the fixation between the two first semi-circular rings 41 and the two second semi-circular rings 42.

[0097] As Figure 4 shown, in a more specific embodiment, the opposite surfaces of the clamping members 11 are arc-shaped surfaces 111 adapted to the electric wire 5.

[0098] It should be noted that when the two clamping members 11 move towards each other, the opposite surfaces will come into contact with the electric wire 5. Therefore, the opposite surfaces of the two clamping members 11 are arc-shaped surfaces 111 adapted to the electric wire 5, which can clamp the circular cross-section electric wire 5 more fittingly and improve the stability of the clamping.

[0099] As Figure 4As shown, in a more specific embodiment, the arc surface 111 is provided with concave-convex patterns 1111 .

[0100] It should be noted that the arc surface 111 is provided with concave-convex patterns 1111 , which can increase the friction between the arc surface 111 and the surface of the wire 5 , and further improve the stability of clamping.

[0101] like Figure 2 As shown, in a more specific embodiment, the first driving member 22 is a hydraulic driving mechanism.

[0102] It should be noted that there are many types of hydraulic drive mechanisms, for example: Patent document CN205949963U discloses a new type of hydraulic shear, the hydraulic drive mechanism includes an oil cylinder and a manual valve mechanism, a piston mechanism is installed in the oil cylinder, the piston mechanism is composed of a piston rod and a piston head arranged at the front end of the piston rod, the front end of the piston head is used to connect with the two wire cutting members 21 through a hinge mechanism, the piston rod is used to push the piston head and drive the hinge mechanism to extend and contract, and drive the two wire cutting members 21 to open or close;

[0103] For example: Patent document CN219464623U discloses a distribution line inspection and trimming device, in which the hydraulic drive mechanism includes a fixed seat, on which a hydraulic drive shaft is provided, and the end of the hydraulic drive shaft away from the fixed seat is used to connect two cutting members 21, and the movement of the hydraulic drive shaft on the fixed seat can drive the two cutting members 21 to open or close.

[0104] The hydraulic drive mechanism is highly efficient, and can achieve power transmission and control through liquid media. It can quickly generate large forces and flexibly adjust speed, which greatly improves work efficiency. The system has a simple structure, streamlined components, and strong reliability.

[0105] In another more specific embodiment, the first driving member 22 is a pneumatic driving mechanism.

[0106] The working process of the present invention is as follows: before cutting the wire, the operator holds the anti-slip wire cutter, the second driving member 3 controls the two clamping members 11 of the clamping assembly 1 to open and controls the first driving member 22 to drive the two wire cutting members 21 of the wire cutting assembly 2 to open, and the wire 5 is placed in the clamping port and the wire cutting port at the same time.

[0107] Afterwards, the second driving member 3 controls the two clamping members 11 to close and clamp the wire 5. Then, the second driving member 3 controls the first driving member 22 to drive the two wire cutting members 21 to close and cut the wire 5. During this process, the two clamping members 11 are always closed to clamp the wire 5, thereby effectively preventing the movable end of the wire from swinging or even falling off.

[0108] Since the second driving member 3 is connected to the clamping assembly 1, and the first driving member 22 of the wire cutting assembly 2 is mounted on the second driving member 3, and the first driving member 22 is connected to two wire cutting members 21 to form the whole anti-dropping wire cutter, an operator can hold the anti-dropping wire cutter with one hand to complete the clamping and wire cutting work, reducing the operation difficulty.

[0109] The second driving member 3 can control the degree of opening or closing of the two clamping members 11, so as to adapt to clamping wires 5 with different diameters, and can also adjust the clamping force of the wire 5 to avoid damaging the structure of the wire 5 due to excessive clamping force.

[0110] In summary, the embodiment of the present invention provides an anti-dropping wire cutter, which can cut the wire on the basis of clamping the wire, avoid the wire from falling after being cut, has a simple structure, and is convenient to operate.

[0111] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
