Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a PCB board fixing table with a function of preventing false soldering, comprising: an adjusting mechanism 2, the adjusting mechanism 2 comprises a position control slot plate 21, the inner wall of the position control slot plate 21 is slidably connected to the bottom of two card slot blocks 24, the tops of the two card slot blocks 24 are provided with a clamping mechanism 3, the clamping mechanism 3 comprises a buckle block 31, the bottom of the buckle block 31 is fixedly connected to the top of the card slot block 24, the two sides of the buckle block 31 are fixedly connected to one side of a pin rod seat 35, the inner walls of the two pin rod seats 35 are rotatably connected to one end of a rocker 36, The other end of the rocker arm 36 is rotatably connected to the two sides of the two-way pin block 37, the outer surface of the two-way pin block 37 is fixedly connected to the middle of the splint 38, and the outer surface of the splint 38 is fixedly connected to the inner wall of the cushion block 39, the inner wall of the two-way pin block 37 is fixedly connected to one end of the limiting pressure block 34, the other end of the limiting pressure block 34 is slidably connected to the inner wall of the limiting groove 32, the limiting groove 32 is opened in the middle of the buckle block 31, one side of the limiting groove 32 is fixedly connected with a spring member 33, and the other end of the spring member 33 is fixedly connected to the middle of one end of the limiting pressure block 34.

[0024] In this embodiment, the setting of the adjustment mechanism 2 can provide stable adjustment and locking functions, and the setting of the clamping mechanism 3 can provide fine-tuning and clamping functions. The two slot blocks 24 can slide in the predetermined slots opened in the control slot plate 21, and the slot blocks 24 provide a fixing function for the buckle block 31, and the buckle block 31 provides a fixing function for the pin rod seat 35. The rod position set on the inner wall of the pin rod seat 35 can allow the connected rocker 36 to rotate within a range, and the other end of the rocker 36 is rotatably connected with the two-way pin rod block 37, and the two-way pin rod block 37 provides a rotatable function, and the two-way pin rod block 37 and the two ends of the pin rod seat 35 are rotatably connected to each other. At this time, when the two-way pin rod block 37 is subjected to pressure, the rocker 36 will be displaced inward and aligned with the pin rod seat The connection between the two-way pin block 35 and the two-way pin block 37 is rotated, and the two-way pin block 37 provides a fixing effect for the clamp plate 38. When the clamp plate 38 is subjected to pressure, the two-way pin block 37 connected to it will be displaced inward, and the clamp plate 38 provides a fixing effect for the cushion block 39. The cushion block 39 is made of a soft rubber material as a whole, which has a certain toughness and a certain viscosity. The limiting pressure block 34 connected to the two-way pin block 37 can slide in the limiting groove 32 opened in the buckle block 31, and the limiting groove 32 opened in the buckle block 31 and the limiting pressure block 34 are connected to each other with a spring member 33. When the limiting pressure block 34 is subjected to pressure from the two-way pin block 37, pressure will be applied to the spring member 33, and the spring member 33 will be deformed when subjected to pressure, and transmit relative force to the limiting pressure block 34.

[0025] Example 2

[0026] like Figure 1-Figure 3 As shown, a rotating groove is provided on one side of the position control slot plate 21, and the inner wall of the rotating groove is slidably and rotatably connected to the outer surface of the bidirectional threaded rod 22, and the outer surface of the bidirectional threaded rod 22 is threadedly connected to one side of two slot blocks 24, and one end of the bidirectional threaded rod 22 is fixedly connected to the inner wall of the handle 23. A fixing mechanism 1 is provided at the bottom of the position control slot plate 21, and the fixing mechanism 1 includes a mounting plate 11, and the top of the mounting plate 11 is fixedly connected to the bottom of the position control slot plate 21, and mounting holes 12 are provided on four sides of the mounting plate 11, and the inner wall of the mounting hole 12 is snap-connected to the outer surface of the external bolt.

[0027] In this embodiment, the control slot plate 21 can slide and rotate the bidirectional threaded rod 22 connected to it through the rotation groove. During the rotation of the bidirectional threaded rod 22, because its relative threads are connected to one side of the two slot blocks 24, when it rotates, the two slot blocks 24 will slide in the predetermined slots opened in the control slot plate 21 in relative directions according to the mutually connected thread grooves, and the slot blocks 24 provide a fixed effect for the buckle blocks 31. When the slot blocks 24 slide, the buckle blocks 31 connected to it will be displaced synchronously. The fixing mechanism 1 provided can provide the effect of interconnection with the external pedestal. The mounting plate 11 provides a fixed effect for the control slot plate 21, and the mounting plate 11 can allow the external bolts to be inserted into it through the mounting grooves and prevent displacement through nuts.

[0028] Working principle:

[0029] like Figure 1-Figure 4 As shown, when two PCB boards need to be welded, after marking the welding places of the two PCBs, the mounting holes 12 opened on the mounting plate 11 are engaged with the bolts on the pedestal, and after engaging, they are connected to each other through the bolts. At this time, the two PCB boards are sent into the middle part of the position control slot plate 21. After being sent in, the handle 23 can be rotated. When the handle 23 rotates, the bidirectional threaded rod 22 connected to it will rotate synchronously. When the bidirectional threaded rod 22 rotates, the two slot blocks 24 connected to it will slide in the position control slot plate 21 in relative directions. When the slot blocks 24 slide, the button blocks 31 connected to it will move synchronously. When the two button blocks 31 are relatively displaced, the pads 39 on the clamping plate 38 provided thereon can clamp the two PCB boards and move them toward the middle. When the two-way pin block 37 is subjected to pressure, the rocker 36 connected to it will rotate inward through the pin seat 35 connected to the buckle block 31, and pressure will be applied to the limiting pressure block 34. When the spring member 33 is subjected to pressure transmitted by the limiting pressure block 34 sliding in the limiting groove 32 opened in the buckle block 31, it will be deformed and provide relative force, which will be transmitted to the two-way pin block 37 and the clamping plate 38 connected to it, so that the connection of the PCB board is connected more tightly and more closely.
