The first fixed block 100 is provided with a plurality of first threaded holes, and the second fixed block 200 is provided with a plurality of second threaded holes. The first screw 300 combines the first fixed block 100 and the second fixed block 200 through the first threaded hole and the second threaded hole to form a fixing fixture, and the fixing fixture is used to place and clamp the tungsten copper block 400.

[0023] The tungsten copper block 400 is generally in the shape of a rectangular parallelepiped.

[0024] The first fixing block 100 is in the shape of an elongated strip, and a first threaded hole is provided on the side of the first fixing block 100. The first threaded hole runs transversely through the first fixing block 100. In a specific embodiment, three first threaded holes are provided, and the three first threaded holes are arranged transversely in a straight line, and the three first threaded holes are distributed at equal intervals.

[0025] The first fixed block 100 is also provided with a first slot 140, which is used to place the tungsten copper block 400. In a specific embodiment, two first slots 140 are provided on the first fixed block 100. The length of the first slot 140 is an integer multiple of the length of the tungsten copper block 400, so that one or more tungsten copper blocks 400 can be placed in the first slot 140. In a specific embodiment, the length of the first slot 140 is three times the length of the tungsten copper block 400, so that three tungsten copper blocks 400 can be placed in each first slot 140.

[0026] The second fixing block 200 is in the shape of an elongated strip, and a second threaded hole is provided on the side of the second fixing block 200. The second threaded hole is arranged horizontally. In a specific embodiment, there are three second threaded holes, which are arranged in a straight line and are evenly spaced. The three second threaded holes correspond one by one to the three first threaded holes.

[0027] The second fixed block 200 is also provided with a second slot 220, the shape of which matches the shape of the first slot 140, and the second slot 220 is used to place the tungsten copper block 400. In a specific embodiment, two second slots 220 are provided on the second fixed block 200. The length of the second slot 220 is an integer multiple of the length of the tungsten copper block 400, so that one or more tungsten copper blocks 400 can be placed in the second slot 220. In a specific embodiment, the length of the second slot 220 is three times the length of the tungsten copper block 400, so that three tungsten copper blocks 400 can be placed in each second slot 220.

[0028] A plurality of first screws 300 are provided, and the first screws 300 are threadedly assembled with the first threaded hole and the second threaded hole, so that the first fixing block 100 and the second fixing block 200 are combined together to form a fixing fixture, and at this time, the first slot body 140 and the second slot body 220 correspond to each other to form a storage groove, and the tungsten steel block is placed in the storage groove. The first fixing block 100 and the second fixing block 200 clamp and fix the tungsten steel block through the first slot body 140 and the second slot body 220. By adjusting the first screw 300, the distance between the first fixing block 100 and the second fixing block 200 can be adjusted, so that tungsten steel blocks of different sizes can be clamped between the first fixing block 100 and the second fixing block 200.

[0029] The first trough body 140 and the second trough body 220 both include a vertical surface 120 and a horizontal surface 130, and the vertical surface 120 and the horizontal surface 130 are perpendicular to each other. Elastic gaskets are fixed on the vertical surfaces 120 of the first trough body 140 and the second trough body 220, and the elastic gaskets are made of silicone material. When the first fixed block 100 and the second fixed block 200 clamp the tungsten steel block, the elastic gasket can not only prevent the tungsten steel block from being damaged during the clamping process, but also effectively increase the friction between the tungsten steel block and the first fixed block 100 and the second fixed block 200, so as to enhance the stability of the support.

[0030] The fixture for evaporating solder on the tungsten copper block 400 further includes a substrate 500 . The substrate 500 is a rectangular plate and is used to fix the first fixing block 100 and the second fixing block 200 .

[0031] A first through hole 110 is provided at each end of the first fixed block 100, and a second through hole 210 is provided at each end of the second fixed block 200. The first through hole 110 passes through the first fixed block 100, and the second through hole 210 passes through the second fixed block 200. A third threaded hole is provided on the substrate 500, and the third threaded hole corresponds to the first through hole 110 and the second through hole 210 one by one. The fixture for evaporating solder on the tungsten copper block 400 also includes a second screw, and the number of the second screws is the same as the number of the third through holes. The second screw passes through the first through hole 110 and fixes the first fixed block 100 on the substrate 500 through the third threaded hole. The second screw passes through the second through hole 210 and fixes the second fixed block 200 on the substrate 500 through the third threaded hole. A plurality of sets of fixing fixtures spaced in parallel are provided on the substrate 500.

[0032] A heat dissipation structure is disposed at the bottom of the substrate 500 to improve heat dissipation efficiency. In a specific embodiment, the heat dissipation structure is a heat dissipation fin.
