During the upward movement, the two sliders 6 will move in the two slide openings 5 ​​respectively. Under the action of the inclined surface pressure, the two slide plates 3 will move toward each other in the horizontal direction until the two slide plates 3 abut against each other. At this time, the protection frame 2 is no longer controlled to move upward, and the hardware pipes will be located in a relatively closed space formed between the protection frame 2, the two slide plates 3 and the platform 1, which can shield the welding area and prevent the welding slag and sparks generated during the welding process from splashing onto the clothes of the staff at will; At the same time, the end of the locking rod 18 will correspond to the position of the locking groove 22. By controlling the end of the locking rod 18 to be inserted into the locking groove 22, the position of the slide plate 3 and the protective frame 2 can be locked. When the lock needs to be released, just pull the pull block 19 to control the end of the locking rod 18 to move out of the locking groove 22, which is convenient and quick.

[0018] The fixing assembly includes a first threaded rod 8 with opposite thread directions at the left and right ends, a T-shaped sliding block 9 symmetrically threadedly sleeved on the first threaded rod 8, two second threaded rods 10 with opposite thread directions at the left and right ends, and a plurality of fixing blocks 11. A slide groove 12 is horizontally opened on the upper surface of the platform 1. The first threaded rod 8 is horizontally rotatably installed in the slide groove 12. A rotation groove 13 is horizontally opened on the upper surface of the sliding block 9. Two second threaded rods 10 are respectively horizontally rotatably installed in the two rotation grooves 13. The plurality of fixing blocks 11 are respectively threadedly sleeved on the two second threaded rods 10 in pairs. The first threaded rod 8 is controlled to rotate by a driving component. The driving component includes a driving motor 14. An installation cavity 15 is opened in the platform 1. The driving motor 14 is fixedly installed in the installation cavity 15, and the output shaft is fixedly connected to one end of the first threaded rod 8. First, the two hardware pipe fittings to be welded are placed between the two pairs of fixing blocks 11 respectively, and then the second threaded rod 10 is rotated to control the fixing blocks 11 symmetrically threadedly sleeved on the second threaded rod 10 to move relative to each other in the horizontal direction until the two fixing blocks 11 are tightly against the hardware pipe fittings, and then the fixing of the hardware pipe fittings is completed, and then the driving motor 14 is started to control the rotation of the first threaded rod 8, and the two sliding blocks 9 symmetrically threadedly sleeved on the first threaded rod 8 will respectively carry the two fixed hardware pipe fittings to move relative to each other in the horizontal direction until the two ends of the two hardware pipe fittings close to each other are against each other; The hardware pipe fittings of different lengths and diameters can be fixed and clamped. The fixable hardware pipe fittings are no longer of a certain length and a certain diameter, thereby improving the practicability of the device.

[0019] The fixed block 11 is fixedly mounted with an air bag 23 on its surface, and the upper surface of the platform 1 is provided with a plurality of hollow rods 24 with one end being designed to be closed, and a piston rod 25 is inserted in the hollow rod 24 in a sliding seal, and a second telescopic spring 31 is provided in the hollow rod 24, and the two ends of the second telescopic spring 31 are respectively fixedly connected to the hollow rod 24 and the piston rod 25, and an air guide hose 26 is fixedly mounted on one end of the hollow rod 24, and the plurality of air guide hoses 26 are respectively connected to the plurality of air bags 23, and the hollow rod 24 is fixedly mounted on the upper surface of the platform 1 through a supporting component, and the supporting component includes a fixed sleeve on the hollow rod 24 The mounting ring 27 and the support rod 28 fixedly mounted on the outer ring wall of the mounting ring 27, the bottom end of the support rod 28 is fixedly connected to the upper surface of the platform body 1, and the multiple piston rods 25 are controlled to move in the horizontal direction by the pressing component, and the pressing component includes two triangular first pressing blocks 29 and two trapezoidal second pressing blocks 30, the two first pressing blocks 29 are respectively fixedly connected to one end of the multiple piston rods 25 located outside the hollow rod 24, and the second pressing blocks 30 are symmetrically fixedly mounted on the inner wall of the protection frame 2, and the inclined surfaces are respectively arranged face to face with the inclined surfaces of the two first pressing blocks 29; When the protection frame 2 is in the process of moving upward, the inclined surfaces of the two first pressing blocks 29 will slide and contact with the inclined surfaces of the two second pressing blocks 30 respectively. Under the action of the inclined surface pressing, the multiple piston rods 25 will all move toward the direction close to the inside of the hollow rod 24. During the movement, the volume inside the hollow rod 24 becomes smaller and the pressure increases. The gas in the hollow rod 24 will rush into the airbag 23 from the air guide hose 26, so that the airbag 23 expands. The expanded airbag 23 will fit tightly with the hardware pipe fittings, increasing the contact area between the fixing block 11 and the hardware pipe fittings, thereby enhancing the effect of fixing the hardware pipe fittings, and avoiding the poor fixing effect of the fixing block 11 on the hardware pipe fittings due to the irregular size of the hardware pipe fittings to be welded; When the welding work is completed, the protective frame 2 is controlled to move downward. At this time, the pressing force exerted by the second pressing block 30 on the first pressing block 29 gradually disappears, and the piston rod 25 will quickly move and reset under the elastic potential energy of the second telescopic spring 31. At this time, the volume inside the hollow rod 24 becomes larger and the pressure decreases. The gas in the airbag 23 will re-enter the hollow rod 24 from the air guide hose 26, and the airbag 23 will also quickly recover.

[0020] The surface of the platform 1 is provided with a placement groove, in which a slag collecting box 16 is slidably arranged, and the bottom wall of the chute 12 is symmetrically and vertically provided with a slag opening 17 connected with the placement groove; The welding slag generated during the welding process will fall on the surface of the platform 1 and the chute 12. The welding slag that falls into the chute 12 is difficult to clean. It only needs to start the drive motor 14 to control the sliding block 9 to move back and forth in the horizontal direction in the chute 12. During the movement of the sliding block 9, the welding slag that falls into the chute 12 will be pushed into the slag collecting box 16 from the multiple slag openings 17, thereby completing the effect of cleaning the welding slag in the chute 12.

[0021] In the present invention, after the hardware pipe fittings to be welded are fixed and abutted against each other by the fixing assembly, the protective frame 2 is controlled to move upward. During the upward movement, the two sliders 6 will move in the two slide openings 5 ​​respectively. Under the action of the inclined surface pressure, the two slide plates 3 will move closer to each other in the horizontal direction until the two slide plates 3 abut against each other. At this time, the protective frame 2 is no longer controlled to move upward, and the hardware pipe fittings will be located in a relatively closed space formed between the protective frame 2, the two slide plates 3 and the platform 1. Then, the position of the protective frame 2 can be locked by the locking assembly. The protective frame 2 and the slide plates 3 can shield the welding area to prevent welding slag and sparks generated during welding from splashing onto the workers' clothes at will.
