DETAILED DESCRIPTION
[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples.

[0024] A preferred embodiment of a double-ended electric soldering iron of the utility model is as follows Figures 1 to 5 As shown, the double-headed electric soldering iron includes a first tweezer handle 1, a second tweezer handle 2 and a rotating assembly 4. The first tweezer handle 1 and the second tweezer handle 2 are the main structure of the double-headed electric soldering iron. The first tweezer handle 1 and the second tweezer handle 2 are hinged by the rotating assembly 4, so that the first tweezer handle 1 and the second tweezer handle 2 can be opened and closed.
[0025] One end of the first tweezers handle 1 and the second tweezers handle 2 are provided with an assembly hole 8, and the other end is provided with a soldering iron tip 3, the assembly hole 8 is used to assemble the rotating assembly 4, and the soldering iron tip 3 is used to solder the electronic components after power is turned on. In this embodiment, the double-headed electric soldering iron further includes a rear cover 9, which is connected to one end of the first tweezers handle 1 and the second tweezers handle 2 with the assembly hole 8, and the rear cover 9 covers the assembly hole 8, and the rear cover 9 is used to protect the connection position of the first tweezers handle 1 and the second tweezers handle 2, and a conductive wire can also pass through the rear cover 9.
[0026] The rotating assembly 4 includes a rotating shaft 41 and an elastic member 42. The rotating shaft 41 passes through the assembly hole 8 on the first forceps handle 1 and the second forceps handle 2. The rotating shaft 41 is the rotation center of the first forceps handle 1 and the second forceps handle 2. The rotating shaft 41 can limit the rotation direction of the first forceps handle 1 and the second forceps handle 2, thereby reducing the deviation of the rotation plane of the first forceps handle 1 and the second forceps handle 2. The elastic member 42 is assembled between the first forceps handle 1 and the second forceps handle 2. The elastic member 42 can apply elastic force to the first forceps handle 1 and the second forceps handle 2 to drive the first forceps handle 1 and the second forceps handle 2 to open. In a natural state without the action of human power, the first forceps handle 1 and the second forceps handle 2 are in a naturally open state due to the action of the elastic member 42.
[0027] The first forceps handle 1 is also provided with a first limiting platform 5, and the second forceps handle 2 is provided with a second limiting platform 6, and the first limiting platform 5 and the second limiting platform 6 are respectively located on the mutually adjacent sides of the first forceps handle 1 and the second forceps handle 2. The first limiting platform 5 and the second limiting platform 6 are both arranged in a staggered manner in a plurality of groups along the up-down direction, and the space between two adjacent first limiting platforms 5 is adapted to the size of the second limiting platform 6, and the space between two adjacent second limiting platforms 6 is adapted to the size of the first limiting platform 5, so that when the first forceps handle 1 and the second forceps handle 2 are closed, the first limiting platform 5 and the second limiting platform 6 are engaged with each other.
[0028] The top and bottom surfaces of the first limiting platform 5 and the second limiting platform 6 are mutually staggered and limited, and the first tweezers handle 1 and the second tweezers handle 2 are limited in the up and down directions to prevent the first tweezers handle 1 and the second tweezers handle 2 from swinging due to their lengths, and ensure that the soldering iron tips 3 at the ends of the first tweezers handle 1 and the second tweezers handle 2 always move on the same plane. The rotating component 4, the first limiting platform 5 and the second limiting platform 6 cooperate with each other to jointly ensure that the soldering iron tips 3 are aligned.
[0029] The double-headed electric soldering iron is provided with a rotating assembly 4 between the first tweezers handle 1 and the second tweezers handle 2, and the rotating shaft 41 of the rotating assembly 4 cooperates with the assembly hole 8. When the first tweezers handle 1 and the second tweezers handle 2 are closed, the rotating shaft 41 serves as the axis to rotate around the center line of the rotating shaft 41. The rotating shaft 41 has a limiting effect on the rotation direction of the first tweezers handle 1 and the second tweezers handle 2, thereby reducing the deviation of the rotation plane of the first tweezers handle 1 and the second tweezers handle 2; at the same time, when the first tweezers handle 1 and the second tweezers handle 2 are closed, the staggered first limit platforms 5 and the second limit platforms 6 are engaged with each other to prevent the first tweezers handle 1 and the second tweezers handle 2 from swinging, thereby ensuring that the soldering iron tips 3 of the first tweezers handle 1 and the second tweezers handle 2 move and align on the same plane, thereby improving the welding quality and efficiency.
[0030] Preferably, the root thickness of the first limiting platform 5 and the second limiting platform 6 is greater than the top thickness, and the top surface and the bottom surface of the first limiting platform 5 and the second limiting platform 6 are both inclined surfaces that are away from each other from the top to the root.
[0031] The top and bottom surfaces of the first limiting platform 5 and the second limiting platform 6 are both inclined surfaces, which have a correction and guiding effect on the first tweezers handle 1 and the second tweezers handle 2. When the first tweezers handle 1 and the second tweezers handle 2 are closed, the horizontal misalignment of the tip of the soldering iron tip 3 is corrected to ensure that the soldering iron tip 3 is horizontally aligned.
[0032] Preferably, the first limiting platform 5 and the second limiting platform 6 are both provided with chamfers 7 at their ends close to each other.
[0033] Chamfers 7 are provided on the first limiting platform 5 and the second limiting platform 6. If the first tweezers handle 1 and the second tweezers handle 2 are misaligned, the chamfers 7 collide with each other for horizontal correction when the first tweezers handle 1 and the second tweezers handle 2 are closed to avoid jamming due to excessive deformation.

Visually, the first limit platform 5 and the second limit platform 6 form a triangular structure. When the first tweezers handle 1 and the second tweezers handle 2 begin to close, the first limit platform 5 and the second limit platform 6 at one end close to the rotating shaft 41 first interlock and bite, thereby reducing the contact area during closing and avoiding jamming. At the same time, the inclined surface has a gradual correction effect as the closing proceeds.
[0036] Preferably, the rotating assembly 4 further includes a bearing 43 , the bearing 43 is fixedly assembled in the assembly hole 8 , and the rotating shaft 41 is fixedly assembled with the bearing 43 .
[0037] The rotating component 4 also includes a bearing 43. The bearings 43 are assembled in the assembly holes 8 of the first tweezers handle 1 and the second tweezers handle 2. The bearing 43 and the first tweezers handle 1, the bearing 43 and the rotating shaft 41 can be installed by a riveting process, which reduces the gap between the bearing 43, the assembly hole 8 and the rotating shaft 41, eliminates the error gap caused by the linkage of multiple accessories, and greatly reduces the horizontal misalignment of the opening and closing of the first tweezers handle 1 and the second tweezers handle 2.
[0038] Preferably, the elastic member 42 comprises a torsion spring, which is sleeved on the rotating shaft 41 , and two ends of the torsion spring are respectively connected to the first tweezers handle 1 and the second tweezers handle 2 .
[0039] The elastic member 42 is a torsion spring, which has a more stable elastic force on the first tweezers handle 1 and the second tweezers handle 2. When the force of manpower on the first tweezers handle 1 and the second tweezers handle 2 is less than the force of the torsion spring, the first tweezers handle 1 and the second tweezers handle 2 can be automatically opened.
[0040] Preferably, the first tweezers handle 1 and the second tweezers handle 2 both include an outer shell 11 and an inner shell 12, the inner shell 12 is snap-fitted with the outer shell 11, the soldering iron tip 3 is inserted into the inner shell 12, the assembly hole 8 is opened in the inner shell 12, and the elastic member 42 is arranged between the inner shells 12 of the first tweezers handle 1 and the second tweezers handle 2.
[0041] The first tweezers handle 1 and the second tweezers handle 2 are both formed by an outer shell 11 and an inner shell 12 that are interlocked. The elastic member 42, the soldering iron tip 3 and the assembly hole 8 are all arranged on the inner shell 12. The outer shell 11 has a protective effect on the inner shell 12 and the structure thereon. The outer shell 11 is the part where people hold their hands during operation. When the first tweezers handle 1 and the second tweezers handle 2 are closed, the force application point of the operator is also on the outer shell 11.
[0042] Preferably, the soldering iron tip 3 comprises an inner core 31 , a heating element 32 and a fixing spring 33 , the inner core 31 is inserted into the inner shell 12 , the heating element 32 is arranged in the inner core 31 , and the fixing spring 33 is press-fitted between the heating element 32 and the inner core 31 .
[0043] The inner core 31 is an external structural part of the soldering iron tip 3. It is an insulating structure and is used to fix the heating element 32 and the fixing spring 33. The heating element 32 can generate heat for electric soldering after being energized. The fixing spring 33 is arranged between the inner core 31 and the heating element 32. The fixing spring 33 applies radial elastic force to fix the heating element 32. At the same time, the fixing spring 33 is also used to connect with the external circuit to energize the heating element 31. In this embodiment, there are three fixing springs 33, which are arranged at intervals along the length direction of the heating element 32 to ensure the assembly accuracy of the heating element 32, so as to ensure that the tips of the two soldering iron tips 3 are in the same plane in the initial state.
[0044] Preferably, a pressing sleeve 13 is also buckled on the housing 11 , and the pressing sleeve 13 is arranged at one end of the housing 11 close to the soldering iron tip 3 .
