Example 1:

a multifunctional electrode holder, as shown in figure 1, comprises a holder body 1 and a holder body sheath 2. The clamp body 1 is made of red copper with good conductivity, and the clamp body 1 is connected with a welding machine through a cable. The clamp body 1 is provided with a jaw, and the clamp body has the functions of clamping the welding rod 11 and conducting current required by welding for the welding rod 11. The clamp body 1 is arranged in the clamp body sheath 2, and the clamp body sheath 2 has the functions of facilitating the holding of the electrode holders by a welder, insulating and heat-insulating, and preventing the welder from electric shock and scalding;

in order to solve the problems in the background art, as shown in fig. 2, a lifting lug is arranged at the lower end of a clamp body sheath 2, and a fan 3 is hinged on the lifting lug through a hinge shaft. Specifically, the hinge shaft is a bolt and a nut, and the nut can moderately lock the lifting lug, so that the rotation of the fan 3 has certain self-locking property. As can be seen from fig. 2, the bolts are perpendicular to the clamping surface of the jaws, and the rotation surface of the fan 3 substantially coincides with the clamping surface of the jaws. In this way, the welding rod 11 can be positioned in the rotation plane of the blower 3 no matter what angle the welding rod 11 is clamped in the jaw. In the embodiment, the jaw of the clamp body 1 adopts a sinking structure, which has the functions of facilitating welding operation and enabling the head end of the welding rod 11 to be close to the air outlet of the fan 3;

after the measures are adopted, when welding operation is carried out, the fan 3 can rotate around the hinge shaft only by manual adjustment and stop at a certain angle, so that the air outlet direction of the fan 3 can be aligned with the welding end of the welding rod 11. It is noted that the fans 3 are not limited to one, and two or more fans 3 may be used in series in order to increase the wind speed;

it is known that toxic gases and fumes generated during welding are rooted in the burning of the coating at high temperatures at the welding end of the electrode 11. During welding, the air outlet direction of the fan 3 can be always aligned to the welding end of the welding rod 11 by adjusting the hinging angle of the fan 3, toxic gas and smoke dust are blown away from the root of smoke generation in the direction away from a welder, and the toxic gas and the smoke dust are prevented from being accumulated around the welder and causing harm to the health of the welder;

a power supply unit is arranged on the electrode holders and is used for supplying power to the fan 3. The power supply unit has three power supply modes, and the first power supply mode is to use the battery to supply power, and the power supply unit has the advantages of simple structure and convenience in use. However, the energy storage of the battery is limited, and the battery needs to be replaced and charged frequently;

the second power supply mode is to convert the welding power supply from the cable connection into a voltage-stabilized power supply through a circuit. The electric power supply device has the advantages that the electric power and the power supply time are not worried, and the fan is powered as long as the electric welder is powered. However, the defects are also obvious, the no-load output voltage of the electric welding machine is about 80V, the welding voltage is about 30V, the voltage fluctuation is large, and most of the welding power is alternating current, an inverter circuit and a voltage stabilizing circuit are needed to convert the welding power into direct current voltage stabilizing power which can be used by a fan and a spotlight, and the cost is high;

the third power supply mode is special, a voltage-stabilized power supply is arranged in the electric welding machine, and the fan is connected with the voltage-stabilized power supply through an electric wire. The voltage-stabilized power supply converts 380V industrial power into direct-current voltage-stabilized power supply which can be used by the fan through a voltage reduction and rectification circuit to supply power for the fan. Obviously, the power supply mode can solve the power supply problem of the fan once and for all, but the electric welding machine needs to be refitted;

in this embodiment, a battery-powered mode is employed. As shown in fig. 1 and 2, a battery box 7 is arranged at the tail end of a clamp body sheath 2, a fan switch 9 is arranged in the middle of the clamp body sheath 2, and a battery in the battery box 7 is electrically connected with a fan 3 through a lead and the fan switch 9;

Specifically, a dovetail-shaped plug-in structure is arranged at the rear end of the clamp body sheath 2, and the battery box 7 can be plugged in the clamp body sheath 2 through the plug-in structure and is electrically connected with the fan 3 through a contact and a wire. The design is to facilitate the replacement of the battery boxes 7 alternately, so that one battery box 7 is powered and the other battery box 7 is charged;

in the embodiment, three rechargeable 18650 lithium batteries are installed in the battery boxes 7, and each battery box 7 can meet the requirement of welding operation for half a day after each battery box 7 is replaced, and can meet the requirement of welding operation for the whole day after each battery box 7 is fully charged for 2-3 hours after each battery box is fully charged;

in order to facilitate the detection of the electric quantity and the charging, an electric quantity display plate 8 and a charging port are arranged on the battery box 7.

Example 2:

unlike embodiment 1, the blower 3 is installed in the housing 4, and the housing 4 has a hinge shaft capable of being hinged with the lifting lug on the clamp body sheath 2;

as shown in fig. 5, the fan 3 is installed in the housing 4, firstly, the housing 4 can protect the fan 3, so that the fan 3 is prevented from being damaged by collision; secondly, the existing fan 3 lacks a hinge structure; thirdly, the serial connection of a plurality of fans 3 is facilitated.

Example 3:

unlike embodiment 2, a raval nozzle structure may be provided on the housing 4;

as shown in fig. 6, the raval nozzle structure is located at the air outlet end of the fan 3, and the raval nozzle structure has a nozzle structure that expands after being received. The Laval nozzle has the effects of collecting wind and increasing the wind speed of the wind, and can enhance the blowing-off strength of toxic gas and smoke dust.

Example 4:

unlike embodiment 2, an LED spotlight 5 is installed at the center of the air outlet of the blower 3, and the irradiation direction of the spotlight 5 is coaxial with the air outlet direction of the blower 3, as shown in fig. 7. During welding, the irradiation direction of the spot lamp 5 can be aligned with the welding end of the welding rod 11 by adjusting the hinging angle of the fan 3. Referring to fig. 1 and 2, a spotlight switch 10 is provided at the middle of the clamp body sheath 2 for controlling the spotlight 5 to be turned on;

when welding is performed in a closed or dark environment, it is difficult for a welder to see the welding position clearly. The spot lamp 5 is arranged on the fan 3 or the shell 4, and the irradiation direction of the spot lamp 5 can be aligned with the welding end of the welding rod 11 while blowing, so that a welder can observe the welding position conveniently. And along with the adjustment of the air outlet angle of the fan 3, the irradiation direction of the spotlight 5 can be adjusted in a following way.

Example 5:

unlike embodiment 1, goggles 6 are mounted on the caliper body sheath 2;

as shown in fig. 8, at the time of welding, as the electrode 11 is shortened, the hinge angle of the blower 3 needs to be constantly adjusted. The welding mask is held by the other hand of the welder, and the hinge angle of the fan 3 cannot be adjusted in real time. The goggles 6 are arranged on the pliers body sheath 2, so that the other hand of a welder can be liberated, and the welder can adjust the hinging angle of the fan 3 in real time on the premise of protecting eyes of the welder, thereby ensuring that the air outlet direction of the fan 3 is always aligned to the welding end of the welding rod 11;

referring to fig. 9, in the present embodiment, the goggles 6 are composed of a universal adjuster 63, a lens mount 62, a lens 61, and a protection edge 64;

specifically, the mirror mount 62 is a plastic member with a resilient snap groove, as shown in fig. 10. The mirror body 61 can be inserted into the elastic clamping groove and clamped and fixed by the elastic clamping groove. The mirror body 61 needs to be replaced after being broken, and the mirror body 61 and the mirror body mounting frame 62 adopt the detachable clamping mode, so that the mirror body 61 can be replaced conveniently and quickly, and the mirror body mounting frame 62 can be reused. A detachable guard edge 64 is arranged on the periphery of the mirror body 61, and the guard edge 64 is formed by bending steel wires. The mirror body mounting frame 62 is provided with a jack and a clamping groove, and the guard 64 is inserted into the jack and clamped by the clamping groove. This limits the freedom of the guard 64 and also facilitates the removal and installation of the guard 64. The perimeter of the mirror body 61 is most prone to shatter due to impact and the guard 64 acts to prevent shattering of the perimeter of the mirror body 61 due to impact. The protective edge 64 can be quickly detached, so that the mirror body 61 can be quickly replaced, and the protective edge 64 can be repeatedly used;

in this embodiment, the universal adjusting member 63 is a universal tube. The universal tube is a metal strip spirally wound tube, and can be bent in a universal manner, and after bending, the universal tube can be kept in a bent state, so that the goggles 6 have universal adjustability. It is noted that the universal tube is one type of universal adjusting structure, and the universal adjusting structure can be a ball head rod, a multi-section rod or other universal adjusting parts;

referring to fig. 11, fig. 11 shows another implementation of the goggles 6. As can be seen from fig. 11, the mirror mount 62 itself has a guard for preventing the collision of the mirror 61, and the mirror mount 62 has a clip-like structure for clipping the mirror 61 to the mirror mount 62. Obviously, this mounting also facilitates the replacement of the mirror body 61;

due to the limitations of welding conditions and the welder's position, the light blocking position of the goggles 6 needs to be adjusted accordingly. The universal adjusting member 63 can adjust the light blocking position of the goggles 6 in a universal manner, so that a welder can perform welding operation in a comfortable posture.

According to the embodiment, the electrode holders have the functions of blowing smoke, lighting, blocking light and protecting eyes, so that a welder can conveniently weld in a non-windy or relatively closed environment, and the welder is prevented from being hurt by toxic gas, smoke dust and arc light.
