[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] The portable electric thermal cutting equipment described in the utility model includes an outer shell 1, which has a battery 11 and a coil 12 built in it. The outer shell 1 is provided with two power-on interfaces 13. Optionally, the power-on interface 13 can be an interface in the traditional sense connected by a male and female connector, or a locking hole 32 on the outer shell 1 through which the power line passes. The coil 12 is a coreless coil 12 formed by spirally winding two wires, and one of the wires is electrically connected to the positive electrode of the battery 11, and the other end is connected to one of the power-on interfaces 13. One end of the other wire is connected to the other power-on interface 13, and the other end is electrically connected to the negative electrode of the battery 11. Specifically, in this embodiment, the outer shell 1 is divided into three layers of space, namely, upper, middle and lower, by an epoxy resin board. The battery 11 is placed in the uppermost space, the coil 12 is placed in the lowermost space, and a switch circuit 14 is placed in the middle layer for controlling the on and off of the circuits of the battery 11 and the coil 12. Optionally, the switch circuit 14 can be a button switch, a contact switch, or a A switch, a toggle switch, or any other form of switch controls the circuit connection between the battery 11 and the coil 12. Specifically, the switch can be fixed on the outer shell 1 so that the operator can contact the switch to change the switch state. The switch circuit 14 is connected in series between the battery 11 and the coil 12, and the switch circuit 14 controls the current on and off. Exemplarily, one end of the switch circuit 14 can be connected to the positive pole of the battery 11, and the other end is connected to the end of a wire in the coil 12. Or in another optional embodiment, the switch circuit 14 can also be embodied in the form of a circuit board, and the switch control of the circuit is realized by arranging corresponding switching devices on the circuit board, such as MOS tubes, triodes, etc. More specifically, the gate of the switching device can be controlled by a weak voltage circuit, the positive pole of the battery 11 is connected to the source of the switching device, and the wire connected to the positive pole of the battery 11 in the coil 12 is connected to the drain of the switching device, so that the switch device is controlled to be on and off by the weak voltage circuit, thereby controlling the circuit on and off between the power supply and the coil 12.In the present embodiment, the battery 11 is a rechargeable lithium battery 11 with a standard voltage of 29.6V (how to charge the lithium battery 11 is a prior art in the art and will not be described in detail here). The number of turns of the wire connected to the positive electrode of the battery 11 is 5, and the number of turns of the wire connected to the negative electrode of the battery 11 is 8-10. The coil 12 improves the stability of the voltage in the DC circuit, so that the current in the circuit can be maintained within the required range for a longer time, and prevents the battery 11 from being insufficiently charged due to long-term discharge. Optionally, in other embodiments, the battery 11 voltage can be controlled to be greater than 20V, so that during use, an arc is formed between the contact of the electrothermal cutting equipment and the object to be cut, and the object to be cut is melted and cut off by high temperature; optionally, the winding method of the two wires forming the coil 12 can be a coil 12 formed by winding around the axis respectively, or a coil 12 formed by winding around the axis in an interlaced manner. At the same time, in order to protect the circuit, a resistor is connected in series to the tail end of the coil 12 wire connected to the negative electrode of the battery 11, and a fuse is connected in series between the coil 12 and the battery 11.

[0032] Two external wires 17, one end of the two external wires 17 are respectively connected to the two power interfaces 13, and the other end is respectively connected to the welding clamp 15 or the jumper clamp. Specifically, one end of one of the wires is connected to one of the power interfaces 13, and the other end is connected to the welding clamp 15, so that the welding clamp 15 is connected to the positive electrode of the battery 11, and one end of the other wire is connected to the other power interface 13, and the other end is connected to the jumper clamp, so that the jumper clamp is connected to the negative electrode of the battery 11. During work, the object to be cut is clamped by the jumper clamp, and then the welding wire or the conductor is fixed on the welding clamp 15. By bringing the welding clamp 15 close to the object to be cut, a loop is formed, and an arc is formed between the welding wire or the conductor and the object to be cut. The object to be cut is melted by the high temperature generated by the arc, thereby completing the demolition;

[0033] The outer shell 1 is also provided with a wire storage unit 2, and the wire storage unit 2 includes a fixed seat 21 and a lap piece 22, the fixed seat 21 and the outer shell 1 are fixedly connected, and a storage space 211 is opened on one side of the fixed seat 21, and one end of the lap piece 22 is hinged to the fixed seat 21, and when the lap piece 22 is rotated to the extreme position, it can be placed in the storage space 211, and the lap piece 22 extends vertically inward from one end of the outer shell 1 to form an anti-detachment portion 221, and a storage space 222 is left between the hinge between the lap piece 22 and the fixed seat 21 and the anti-detachment portion 221, and a torsion spring is provided between the lap piece 22 and the fixed seat 21, one of the legs of the torsion spring is against the fixed seat 21, and the other leg is against the bottom of the lap piece 22, and when the storage unit When the element is in a natural state, the overlap plate 22 is placed in the accommodating space 211. When the cutting equipment is not needed, the external wire 17 can be rolled up and wrapped around the overlap plate 22. Specifically, the overlap plate 22 is flipped outward from the accommodating space 211 to expose the accommodating space 222 to the outside. Then, the external wire 17 is wrapped around the overlap plate 22 and the wire is placed in the accommodating space 222. After the winding is completed, under the action of the torsion spring, the overlap plate 22 is flipped into the accommodating space 211, so that the overlap plate 22, the anti-slip portion 221 and the fixing seat 21 surround and form a closed space to prevent the rolled-up external wire 17 from falling off the overlap plate 22, thereby reducing the space occupied by the external wire 17 to facilitate the police to carry it. In this embodiment, there are two wire storage units 2, and the two external connection interfaces are respectively placed on both sides of the outer shell 1, and the two wire storage units 2 are also respectively placed on both sides of the outer shell 1, so that the two external wires 17 can be stored through the two ear wire storage units 2 respectively. At the same time, in an emergency situation where welding is required, only the welding clamp 15 or the overlapping clamp 16 needs to be pulled outward, and the overlapping plate 22 is flipped outward under the action of external force, so that the external wire 17 can be more conveniently detached from the overlapping plate 22.

[0034] One side of the outer shell 1 is also provided with a slide groove, and the sliding plate 3 is slidably connected to the slide groove, one end of the slide groove is closed, and the other end is connected to the outside. When the sliding plate 3 moves to the extreme position, it can abut against the closed end of the slide groove. A shoulder strap 31 is fixed on the sliding plate 3 to facilitate the police officer to carry the cutting equipment. Specifically, during use, since the equipment with batteries 11, wires, coils 12, welding pliers 15, and lap joint pliers 16 is relatively heavy, it is inconvenient to get up after being carried on the ground. The sliding plate 3 can be carried on the body first, and then the cutting equipment can be matched with the skateboard through the cooperation of teammates, so that the top of the skateboard abuts against the end of the slide groove, which reduces the burden on the person carrying it, and at the same time, in order to To further increase the applicable scenarios, the cutting machine is carried and used when a person is rappelling or hanging upside down. The sliding plate 3 and the outer shell 1 are respectively provided with locking holes 32, and when the sliding plate 3 moves to the extreme position, the locking hole 32 of the sliding plate 3 and the locking hole 32 of the outer shell 1 correspond to each other, and an anti-slip pin is inserted into the two locking holes 32, thereby completing the locking between the cutting machine and the sliding plate 3 to prevent the cutting machine from slipping. The anti-slip pin can be a columnar structure. After the anti-slip pin is inserted into the locking hole 32, the anti-slip pin will not slip out due to the police officer's body blocking it. Optionally, a clamping structure can also be provided in the locking hole 32 of the sliding plate 3 or the outer shell 1 to cooperate with the anti-slip pin to prevent the anti-slip pin from slipping.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
