After the adjustment is completed, the fixing bolt 13 is rotated to rotate the movable plate 11 and the movable frame 10, and then the fixing cap 15 threadedly connected to the outer surface of the fixing rod 14 is rotated. At this time, the fixing cap 15 and the connecting plate 16 are rotated, and the connecting plate 16 drives the movable frame 10 to slide with the fixed rod 14 through the auxiliary plate 17, and then drives the movable frame 10 to slide with the fixed disk 8. At this time, the movable frame 10 drives the movable plate 11 and the pressure plate 12 to move to the left, so that the pressure plate 12 stably clamps the electronic device.

[0020] Embodiment 2: The existing electric welding machine will generate bright light during the welding process, which may cause damage to the eyes of people around, and may even generate sparks flying outward, and the protection effect is poor. Therefore, by setting, a support plate 23, an electric telescopic rod 24, a mounting plate 25, a support rail 26, a fixing plate 27, an electric welding machine body 28, an electric welding machine welding head 29 and a buffer protection mechanism 30, the buffer protection mechanism 30 includes a buffer protection tube 31 sleeved on the outside of the electric welding machine welding head 29, a buffer rubber pad 32 fixedly connected to the left side of the buffer protection tube 31, a buffer rod 33 for connection and a second spring 34 sleeved on the outer surface of the buffer rod 33, a plurality of groups of buffer rods 33 are fixedly connected to the left side of the fixing plate 27, and the buffer rods 33 are A left-right sliding structure is formed between the buffer protective tube 31, the buffer protective tube 31 moves left-right on the outside of the welding head 29 of the welding machine, and the left end of the welding head 29 of the welding machine does not extend out of the opening of the left end of the buffer protective tube 31, the upper right end of the base 1 is fixedly connected with a support plate 23, and the front and rear ends of the support plate 23 are fixedly installed with an electric telescopic rod 24, the movable end of the electric telescopic rod 24 is fixedly connected with a mounting plate 25, and a left-right sliding structure is formed between the lower end of the mounting plate 25 and the support rail 26, the support rail 26 is fixedly connected to the middle of the upper end of the base 1, the upper left end of the mounting plate 25 is fixedly connected with a fixing plate 27, and the welding head 29 of the welding machine is penetrated through the hole in the middle of the fixing plate 27, such as Fig.13 , Fig.14 and Fig.15 As shown, after the electronic device is clamped, the end of the welding head 29 of the welding machine is wiped and cleaned to prevent solder from being placed at the port and keep the port clean, thereby effectively preventing cold soldering. The welding head 29 of the welding machine is started, and the electric telescopic rod 24 is started at the same time to push the mounting plate 25 and the support rail 26 to slide. The mounting plate 25 moves to the left, and the mounting plate 25 drives the welding machine body 28 and the welding head 29 of the welding machine to move to the left to perform welding operations on the electronic device. In addition, in the actual welding process, before the end of the welding head 29 of the welding machine contacts the electronic device, The left end of the buffer protective tube 31 and the buffer rod 33 are in contact with the electronic device or the fixed plate 8. At this time, the buffer protective tube 31 is squeezed, and the buffer protective tube 31 and the buffer rod 33 slide. The buffer protective tube 31 squeezes the second spring 34, causing the second spring 34 to undergo elastic deformation. At this time, the buffer rubber pad 32 moves to the right, that is, the welding head 29 of the electric welding machine extends from the buffer protective tube 31 to perform welding operations on the electronic device. Through the setting of the buffer protective tube 31, the bright light and sparks generated during the welding process can be effectively prevented from causing harm to personnel.

[0021] Embodiment 3: In the existing electric welding machine, when welding, when it is necessary to weld electronic components at different positions and angles, it is necessary to loosen the fixation of the components through the clamping assembly, disassemble and adjust them, and then re-fix them. The operation steps are cumbersome, which affects the welding efficiency of the components. Therefore, by setting a vertical plate 2, a fixed long cylinder 3, an adjusting screw rod 4, a movable block 5, a support frame 6, a movable column 7, a fixed disk 8, a connecting frame 18, a connecting block 19, a first spring 20, a positioning plate 21 and a fixing groove 22, the vertical plate 2 is welded to the upper left end of the base 1, and the upper right end of the vertical plate 2 is fixedly connected with a horizontal fixed long cylinder 3, and the fixed long cylinder The middle part of the support frame 3 is rotatably connected with an adjusting screw rod 4, and the adjusting screw rod 4 is threadedly connected to the movable block 5, and the movable block 5 is slidably connected to the middle part of the fixed long cylinder 3. The outer surface of the support frame 6 is sleeved with a connecting frame 18, and the front and rear ends of the support frame 6 are fixedly connected with connecting blocks 19, and an up and down sliding structure is formed between the connecting block 19 and the connecting frame 18, and the upper end of the connecting frame 18 is fixedly connected with a positioning plate 21, and a first spring 20 is arranged between the lower end of the connecting frame 18 and the support frame 6, and the right end of the positioning plate 21 is inserted into the fixed groove 22 at the corresponding position, and the fixed groove 22 is arranged at an equal angle on the outer surface of the movable column 7, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 , Fig.12 and Fig.13 As shown, in the actual welding process, when it is necessary to weld different positions of the electronic device, by rotating the adjusting screw rod 4 threadedly connected to the middle part of the fixed long cylinder 3, the adjusting screw rod 4 drives the movable block 5 to slide forward or backward in the fixed long cylinder 3, so that the fixed plate 8 drives the electronic device to move forward and backward, and the connecting frame 18 can also be pulled upward to slide between the connecting frame 18 and the connecting block 19. At this time, the connecting frame 18 squeezes the first spring 20, and the first spring 20 undergoes elastic deformation. The connecting frame 18 drives the positioning plate 21 to move upward, so that the positioning plate 21 moves out of the fixing groove 22, thereby loosening the limit between the support frame 6 and the movable column 7, and then Then rotate the fixed disk 8, the fixed disk 8 drives the movable column 7 and the support frame 6 to rotate, thereby driving the electronic device to rotate, and the movable block 5 slides in the fixed long cylinder 3, and rotates between the movable column 7 and the support frame 6, so that the welding position of the electronic device can be adjusted without disassembling the electronic device, which simplifies the actual operation steps and improves the welding efficiency of the electronic device. After the adjustment is completed, directly release the connecting frame 18. At this time, the first spring 20 restores the elastic deformation, pushes the connecting frame 18 to move downward, drives the right end of the positioning plate 21 to be inserted into the fixed groove 22 at the corresponding position, and limits the movable column 7 and the support frame 6.
