The pressure plate 5 is an iron product that can be bent under pressure, and is used to press the lower end of the heat exchanger support rod. The height of the lower inner wall of the passage opening 4 is the same as the height of the lower inner wall of the anti-slip groove 7. When assembling the heat exchanger, the lower surface of the pressure plate 5 is in close contact with the lower inner wall of the anti-slip groove 7, and the relationship between the passage opening 4 and the lower inner wall of the anti-slip groove 7 is used to increase the effect of the pressure plate 5.

[0025] The pedal 3 is rotatably connected to the end of the placement plate 2 with a pressure plate 5. The pressure plate 5 and the pedal 3 clamp the front and rear ends of the pressure plate 16. The pressure plate 5 is used to limit the range of movement of the pressure plate 5 and improve the stability of the pressure plate 5 when it is in action. A storage groove 6 is provided on the side of the pedal 3 away from the placement plate 2. When the heat exchanger is not assembled, the pressure plate 5 is located inside the storage groove 6. The width of the storage groove 6 is smaller than the width of the pressure plate 5, and the pressure plate 5 does not completely enter the interior of the storage groove 6. The storage groove 6 is used to store unused pressure plates 5, wherein a portion of the pressure plate 5 is exposed to the outside to improve the convenience of taking the pressure plate 5.

[0026] A limiting groove 13 is provided on the upper surface of the base 1. The limiting groove 13 surrounds the placement plate 2. The internal sliding connection of the limiting groove 13 is an automatic telescopic rod 8. The limiting groove 13 provides a replacement space for the automatic telescopic rod 8. The upper end of the automatic telescopic rod 8 is fixedly connected to a mounting plate 18. A ball 17 is rotatably connected at the center point of the upper surface of the mounting plate 18. The upper end of the ball 17 is fixedly connected to the storage box 10. When assembling the heat exchanger, bolt parts are placed inside the storage box 10. The length and width of the mounting plate 18 are greater than the length and width of the storage box 10. The edge of the lower end of the storage box 10 is in a tilted state and is in close contact with the upper surface of the mounting plate 18. The ball 17 is used to provide the storage box 10 with conditions for rotating and tilting relative to the mounting plate 18.

[0027] The interior of the storage box 10 is fixedly connected with multiple long rods 11, which divide the storage box 10 into two storage spaces, upper and lower. The long rods 11 are used to separate large and small bolt parts. The right surface of the mounting plate 18 is fixedly connected with a storage bag 9. When the device is used, tools for fixing bolts are placed inside the storage bag 9. The storage bag 9 is used to store the work of assembling the heat exchanger. The interior of the storage box 10 is slidably connected with a load-bearing plate 12. The load-bearing plate 12 passes through the right surface of the storage box 10, and the load-bearing plate 12 is located above the long rods 11. The load-bearing plate 12 is used to isolate the long rods 11. The front surface of the storage box 10 is provided with an access opening 14, which is located below the long rods 11, and the access opening 14 is provided with a sealing plate 15. The access opening 14 is used to take the bolt parts below the storage box 10.

[0028] Working principle: First, slide the storage box 10 to a position that does not affect the placement of the heat exchanger outer box and extract the pressing piece 16, then place the heat exchanger shell inside the anti-slip groove 7. If a support rod is provided at the lower end of the heat exchanger shell, bend the removed pressing piece 16 and make the front and rear ends of the pressing piece 16 pass through the passage opening 4, so as to use the pressing piece 16 to press the edge of the support rod, and then flip down the pressing plate 5, and use the pressing plate 5 to press the front and rear sides of the pressing piece 16. The bolt parts are in a state of separation of large and small bolts before being placed in the storage box 10. The large-diameter bolts are directly placed on the long rod 11, and the small-diameter bolts are placed under the long rod 11.

[0029] When large and small bolts are in a mixed state, dump the bolts directly into the storage box 10 from above. Note that before dumping the bolts, use the load-bearing plate 12 to isolate the long rod 11 to prevent the falling bolts from damaging the long rod 11. After the bolts are dumped, pull out the long rod 11, and then overturn and tilt the storage box 10. At this time, the bolts with small diameters pass through the gaps between the long rods 11 and fall under the long rods 11. The automatic telescopic rod 8 changes the height of the storage box 10, and the limiting slide 13 provides the storage box 10 with the conditions for changing its position, thereby ensuring that the storage box 10 is always in the most comfortable taking state.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
