[0009] A further preferred solution of the utility model is that external power output ports are provided at middle positions on both sides of the double gears.

[0010] A further preferred solution of the utility model is that the telescopic handle and the fixed handle are both installed on the control panel, and the telescopic handle and the fixed handle cooperate with each other.

[0011] A further preferred solution of the utility model is that the movable blade is arc-shaped, a blade is arranged on the inner side of the movable blade, and a transmission tooth is arranged on the outer side, and the movable blade is connected with the double gear through the transmission tooth.

[0012] A further preferred solution of the utility model is that the fixed blade is arc-shaped, a blade is arranged on the outer side of the fixed blade, and the outer side of the fixed blade matches with the inner side of the movable blade.

[0013] The utility model has the following benefits:

[0014] The utility model is provided with a telescopic handle, a fixed handle, an external power output port, a double gear, a ratchet and a bevel rack. It can not only be used by manual control of the telescopic handle and the fixed handle, but also can realize electric cable cutting by inserting an electric wrench into the external power output port, thereby solving the problem of the single structure of the existing bolt cutters and increasing the practicality and reliability of the bolt cutters.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] according to Figure 1-3 As shown, a manual and electric dual-purpose bolt cutter comprises a control panel 1, a double gear 2 is mounted on the control panel 1, the rear bottom of the double gear 2 is matched with a ratchet 9 and a bevel rack 10 respectively, the ratchet 9 is provided for preventing the blade from moving in the opposite direction when the telescopic handle 8 and the fixed handle 7 are manually operated, the bevel rack 10 is fixedly connected to one end of the telescopic handle 8, a fixed handle 7 is provided on one side of the telescopic handle 8, a movable blade 3 is matched and connected to the top of the front side of the double gear 2, the top of the movable blade 3 is rotatably connected to one end of a fixed blade 4, and the other end of the fixed blade 4 is fixedly connected to the control panel 1.

[0021] External power output ports 5 are provided at the middle positions on both sides of the double gear 2. Such a configuration can be used to connect to the most common electric wrench on the market, and the electric wrench provides power to drive the movable blade 3 to cut the cable.

[0022] The telescopic handle 8 and the fixed handle 7 are both mounted on the control panel 1 , and the telescopic handle 8 and the fixed handle 7 cooperate with each other. The telescopic handle 8 provided here is rotatably connected to the control panel 1 , and the fixed handle 7 is fixedly connected to the control panel 1 .

[0023] The movable blade 3 is arc-shaped, with a blade provided on the inner side of the movable blade 3 and a transmission tooth 6 provided on the outer side. The movable blade 3 is connected with the double gear 2 through the transmission tooth 6. The movable blade 3 can rotate 360° around the axis to ensure that cables of different diameters can be placed in the jaws of the wire cutter.

[0024] The fixed blade 4 is arc-shaped, and a cutting edge is arranged on the outer side of the fixed blade 4 . The outer side of the fixed blade 4 matches with the inner side of the movable blade 3 .

[0025] Working principle: When the external power output port 5 of the double gear 2 is connected to the electric wrench, the double gear 2 will drive the movable blade 3 to rotate. Since the double gear 2 is the driving wheel and the number of teeth is smaller than the number of teeth of the movable blade 3, when the electric wrench gives power to the double gear 2, a large torque will be generated on the movable blade 3 to cut the cable.

[0026] When the telescopic handle 8 is manually controlled, due to the principle of leverage, the telescopic handle 8 will drive the bevel rack 10 to move, and the bevel rack 10 will push the teeth of the double gear 2 to rotate, and the double gear 2 will drive the movable blade 3 to move. Since the length of the ratchet 9 is much smaller than the length of the manual pressure handle, by utilizing the principle of leverage, a large force change is not required to make the blade generate a large torque to cut the cable.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
