A heating tube 170 is provided inside the handle 100 along the length direction of the handle 100, and one end is connected to the cutter head 110. The heating tube 170 is used to heat the cutter head 110. An electromagnetic coil 160 is wound around the outer side of the heating tube 170 along the length direction of the heating tube 170 and is used to electromagnetically heat the tube 170. It should be noted here that the present invention uses a mold single-head heating tube 170, and one end of the heating tube 170 is in full contact with the cutter head 110 for heat conduction.

[0039] In this embodiment, the first connection portion 150 at the top of the handle 100 is fixedly connected to the handle 100. The limiting block 120 is connected to the external thread of the first connection portion 150 via an internal thread.

[0040] In some specific embodiments, the first connecting portion 150 is a hollow cavity that communicates with the handle 100. It should be noted that one end of the heating tube 170 can extend from the first connecting portion 150 at the top of the handle 100 to the interior of the stopper 120, contacting the blade head 110, thereby heating the blade head 110.

[0041] In some specific embodiments, a first limiting hole 122 is defined at one end of the limiting block 120 adjacent to the first connecting portion 150 . The first limiting hole 122 is provided with an internal thread matching the external thread of the first connecting portion 150 .

[0042] In some specific embodiments, the limiting block 120 is in the shape of a hexagonal prism. A groove is formed at one end of the limiting block 120 away from the connecting portion. A second limiting hole 121 is also formed on the side wall of the limiting block 120.

[0043] In some specific embodiments, a second connecting portion 111 is provided at one end of the cutter head 110 adjacent to the limiting block 120. A protrusion 112 is provided on a sidewall of the second connecting portion 111. The protrusion 112 is configured to be engaged with the second limiting hole 121 of the limiting block 120.

[0044] In this embodiment, the second connecting portion 111 of the cutter head 110 is also in the shape of a hexagonal prism. It can be inserted into the groove of the limit block 120. It should be noted that after the second connecting portion 111 of the cutter head 110 is inserted into the groove of the limit block 120, the protrusion 112 on the second connecting portion 111 can be limited in the second limiting hole 121 on the side wall of the limit block 120. It should also be noted that the interior of the second connecting portion 111 is a hollow structure. An elastic component is installed on the inner side wall of the second connecting portion 111. The elastic force direction of the elastic component is toward the second limiting hole 121 of the limit block 120. One end of the protrusion 112 is fixed to the elastic component. A telescopic hole for the protrusion 112 is also provided on the side wall of the second connecting portion 111. The protrusion 112 is away from one end of the elastic component and can extend from the telescopic hole of the protrusion 112 and be provided in the second limiting hole 121 of the limit block 120. It should be noted that the elastic component can be a spring.

[0045] When installing or replacing the cutter head 110, one only needs to manually press the protrusion 112 into the interior of the second connecting portion 111, then insert the cutter head 110 into the groove of the limit block 120, adjust the orientation, and when the telescopic hole of the protrusion 112 is aligned with the second limit hole 121 of the limit block 120, the protrusion 112 will automatically pop out and get stuck in the second limit hole 121. When the cutter head 110 needs to be removed, the protrusion 112 is manually pressed into the interior of the second connecting portion 111 and pulled outward with force, which is convenient and quick to operate.

[0046] In some specific embodiments, the end of the blade head 110 away from the handle 100 is in the shape of a "I" or a "X" or a "M".

[0047] In some specific embodiments, a non-slip leather cover 130 is further included. The non-slip leather cover 130 is covered on the outside of the handle 100 and is provided with non-slip stripes.

[0048] In some embodiments, a rear cover 140 is further provided at an end of the handle 100 away from the blade 110. A mounting groove is provided within the rear cover 140 for securing the heating tube 170. It should be noted that the mounting groove securely secures the heating tube 170 so that the heating tube 170 does not wobble within the handle 100 when the screwdriver is in use.

[0049] In some specific embodiments, a power supply is further included to supply power to the heating tube 170 and the electromagnetic coil 160 .

[0050] In some specific embodiments, a power supply connection hole 141 is further provided at the bottom of the rear cover 140 for connecting to a power supply.

[0051] In this embodiment, the electromagnetic coil operates on the principle of electromagnetic induction, commonly known as an inductor. When current flows through a conductor, it generates a certain electromagnetic field around it. The conductor itself, in turn, induces other conductors within this electromagnetic field. The effect on the conductor generating the electromagnetic field is called "self-induction," meaning the changing current generated by the conductor itself generates a changing magnetic field, which in turn influences the current in the conductor. The effect on other conductors within this electromagnetic field is called "mutual induction."

[0052] The working principle of the electric heating tube is based on the thermal effect of electric current. Heat is generated by energizing the resistance wire, and then transferred to the surface of the metal tube through the heat-conducting medium, thereby heating the surrounding objects or media.

[0053] Working method of the utility model:

[0054] When it is necessary to remove rusty or difficult-to-remove screws, connect the multifunctional screwdriver to the power supply. At this time, the electromagnetic coil 160 will generate a strong electromagnetic field, and the electric heating tube 170 will generate heat. The electromagnetic coil 160 and the electric heating tube 170 will transfer the generated electromagnetic properties and heat to the cutter head 110, heating and magnetizing the cutter head 110. First, the electric heating tube 170 heats the screw through the heated cutter head 110. The heating temperature should be moderate to avoid damaging the screw or surrounding materials. Then wait for cooling: After heating, wait for the screw to cool. This step is critical, because the cooled screw will shrink, and the friction between the nut will decrease, making disassembly easier. Removing the screw: After the screw cools, since the cutter head 110 is electromagnetically magnetized, when the screw has been heated and cooled to a certain degree, it will be easily removed from its original position.

[0055] By adopting the above technical solution disclosed in the utility model, the following beneficial effects are obtained:

[0056] The utility model discloses a multifunctional screwdriver that is easily unloaded, comprising a handle 100 and a hollow cavity.
