[0008] Further, the fixing part includes an adjusting component, the adjusting component is installed on the bottom plate; and a fixing component, the fixing component is arranged on the top of the bottom plate; wherein, the fixing component is installed on the adjusting component.

[0009] Furthermore, the adjusting component includes a plurality of long holes formed in the bottom plate. A plurality of adjusting sliders are provided at the bottom of the bottom plate, and a cylindrical groove is formed in each of the plurality of adjusting sliders. Among them, there are four adjusting sliders, and the four adjusting sliders are in a T shape. The four adjusting sliders are adapted to the plurality of long holes. When sliding in the long holes, they drive the fixing block to move to adapt to the fixing requirements of PCB boards of different sizes.

[0010] Furthermore, the fixing component includes a plurality of fixing blocks provided on the top of the bottom plate. A mounting rod is fixedly connected to the bottom of each of the plurality of fixing blocks, and a cross groove is formed in the top of each of the plurality of mounting rods. Among them, there are four fixing blocks. The plurality of fixing blocks are respectively threadedly connected to the adjusting sliders through the plurality of mounting rods and the plurality of cylindrical grooves. By threadedly connecting the cylindrical grooves with the adjusting sliders, the installation and disassembly of the fixing blocks are realized.

[0011] Furthermore, the lifting part includes a support component provided at the central axis of the bottom plate, and a lifting component provided on the top of the bottom plate. Among them, the lifting component is installed in the support component.

[0012] Furthermore, the support component includes a fixing hole formed at the central axis of the bottom plate. An adjusting block is fixedly connected to the inner wall of the fixing hole. Two rectangular grooves are formed in the inner wall of the adjusting block, and a Hall element is provided on the adjusting block. Among them, the adjusting block is in a T shape. The Hall element is adapted to the two rectangular grooves, and the Hall element is in contact with the two rectangular grooves to fix the horizontal position of the Hall element. At the same time, it allows the sliding plate to drive the Hall element to move vertically to achieve height adjustment.

[0013] Furthermore, the lifting component includes a sliding plate provided in the adjusting block. A screw is rotatably connected to the bottom of the sliding plate, and a fixing member is installed on the screw. Among them, the front side and the rear side of the sliding plate respectively extend into the two rectangular grooves, and the sliding plate is slidably connected to the two rectangular grooves.

After the adjustment is completed, the fixing nut is tightened to fix the screw at the bottom of the adjusting block to prevent the Hall element from shifting during welding.

[0014] The present invention has the following beneficial effects:

[0015] (1) By setting the fixing part, when fixing the PCB board, the adjusting slider is placed into the corresponding long hole. Subsequently, a screwdriver is used to rotate the fixing block through the cross slot. At this time, the fixing block and the adjusting slider are connected through the mounting rod and the cylindrical groove, so that the adjusting slider and the fixing block are respectively fixed on the top and bottom of the bottom plate. Through the same process as above, several adjusting sliders and several fixing blocks are respectively fixed on the bottom plate. At this time, a screwdriver is used to drive the fixing block and the mounting rod to rotate through the cross slot, so that the fixing block is in a loose state of rotation. Through the same process as above, several fixing blocks are in a loose state of rotation. Subsequently, the distance between several fixing blocks is adjusted by adjusting the sliding state of several adjusting sliders in the long hole. Then, the PCB board is placed on the top of the Hall component, and the distance between several fixing blocks is adjusted. Then, several fixing blocks are tightened to fix the PCB board. After the fixing is completed, the PCB board and the Hall component are welded by welding, which can easily adapt to PCB boards of different sizes. Whether it is a small precision circuit board or a large PCB board, fixation can be achieved, greatly enhancing the versatility of the tooling, preventing the PCB board from shifting due to factors such as vibration and external force, ensuring the docking of the welding position between the Hall component and the PCB board, and guaranteeing the welding quality;

[0016] (2) By setting the lifting part, when adjusting the height of the Hall component, the Hall component is placed into the two rectangular grooves in the adjusting block. At this time, the bottom of the Hall component will slide onto the top of the sliding plate. Subsequently, the handle is rotated to drive the screw to rotate. At this time, the screw rotates and moves upward on the sliding plate, thus lifting the sliding plate to slide and move upward in the two rectangular grooves. By rotating the screw in the opposite direction, the height of the Hall component is reduced to adjust the height of the Hall component. When the height adjustment of the Hall component is completed, the fixing nut is rotated to move upward on the screw and contact the bottom of the adjusting block. At this time, the screw is fixed, so as to fix the position of the Hall component, enabling fine adjustment of the height of the Hall component as needed, conveniently and quickly meeting different welding requirements, preventing the component from shifting due to factors such as vibration and external force collision during the welding process, and ensuring the stability of the welding process and the welding quality.
