[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1-5 As shown, this utility model provides an adjustable PCB board electroplating hanger, including a top arm 1. Two sliders 2 are slidably connected inside the top arm 1. A connecting rod 3 is fixed to one of the opposite ends of the two sliders 2. The opposite ends of the two connecting rods 3 pass through the top arm 1 and are respectively fixed to side arms 4. Side rods 5 are slidably connected to the bottom ends of the two side arms 4. A bracket 6 is fixed to the bottom end of the two side rods 5. A first stud 11 is fixed to the bottom end of the top arm 1. A bottom arm 7 is threadedly connected to the outer arm of the first stud 11. Both ends of the bottom arm 7 are provided with slots 8 that match the bracket 6. A second limiting block 18 is fixed to the top end of the slider 2. The top end of the second limiting block 18 passes through the top arm 1 and is fixed to a support plate 19. The top end of the support plate 19 is provided with a locking structure 20 for locking the position of the slider 2. Multiple fixing brackets 13 are fixed to the top end of the bottom arm 7. A second stud 14 is threadedly connected to one end of the fixing bracket 13. A clamping plate 15 is rotatably connected to one end of the second stud 14 located inside the fixing bracket 13.

[0017] The overall effect of Embodiment 1 is that, through the arrangement of two sliders 2 and two connecting rods 3, the distance between the two side arms 4 and the top arm 1 can be adjusted, reducing the floor space. The side rods 5 are slidably connected to the bottom ends of the side arms 4, allowing adjustment of the overall length of the two side arms 4, further reducing the floor space. The first stud 11, threadedly connected to the bottom arm 7, allows the bottom arm 7 to be rotated closer to the top arm 1, further reducing the floor space. All three components of this device—top arm 1, side arms 4, and bottom arm 7—are adjustable, reducing the floor space by 50% when not in use, thus enhancing its practicality. When unfolding the device, simply rotate the bottom arm 7 threadedly to the bottom of the first stud 11, then pull the two side arms... 4. Maximize the distance between the top arm 1 and the bottom arm 4. Then, guided by the card holder 6 and the card slot 8, push the two side arms 4 to move towards each other, so that the card holder 6 enters the card slot 8. On the one hand, limit the position of the bottom arm 7 to prevent it from rotating. On the other hand, limit the position of the side rod 5 to prevent it from sliding in the side arm 4. Finally, lock the position of the two sliders 2 through the locking structure 20, thereby locking the position of the connecting rod 3 and the side arm 4, achieving the effect of unfolding the device. By placing the PCB board in the fixed frame 13, the user rotates the rotating plate 16, which drives the second stud 14 to rotate, so that the clamping plate 15 moves under the limitation of the inner cavity of the fixed frame 13, thereby clamping and fixing the PCB board.

[0018] Example 2, as Figure 1-5 As shown, the locking structure 20 includes a bracket 2001 fixed to the top of the support plate 19. A locking post 2002 is slidably connected inside the bracket 2001. The bottom end of the locking post 2002 passes through the support plate 19 and is movably inserted into the top arm 1. A pull plate 2003 is fixed to the top of the locking post 2002. A spring 2004 is fixed between the pull plate 2003 and the bracket 2001 on the outside of the locking post 2002. First limiting blocks 9 are fixed to both ends of the side rod 5. First limiting grooves 10 matching the first limiting blocks 9 are opened at both ends of the inner arm of the side arm 4. One end of the pull plate 2003 is fixed with a limiting groove. Plate 21, limiting plate 21 is slidably connected to limiting post 22, the bottom end of limiting post 22 is fixed to support plate 19, the top end of limiting post 22 is fixed with second baffle 23, the top end of top arm 1 is provided with multiple locking holes 24 matching locking post 2002, the opposite ends of clamping plate 15 and fixing frame 13 are both fixed with rubber pads 17, the end of second stud 14 located outside fixing frame 13 is fixed with rotating plate 16, the top end of top arm 1 is fixed with hook 25, the top end of top arm 1 is provided with moving groove matching second limiting block 18, the bottom end of first stud 11 is fixed with first baffle 12.

[0019] The effect achieved by the entire embodiment 2 is that when the user pulls the pull plate 2003 upward, the locking post 2002 can be moved upward, causing the locking post 2002 to disengage from the locking hole 24 on the top arm 1. At this time, the user can pull the side arm 4 to move it. When it moves to the appropriate position, the locking post 2002 will move downward under the return thrust of the spring 2004. The locking post 2002 will then insert into the corresponding locking hole 24 at the top of the top arm 1, locking the position of the slider 2, thereby locking the positions of the two side arms 4. Through the setting of the limiting plate 21, the limiting post 22, and the second baffle 23, the pull can be locked. The upward pulling distance of plate 2003 is limited to prevent the pin 2002 from detaching from bracket 2001, thus enhancing stability. The first limiting block 9 and the first limiting groove 10 limit the side rod 5 to prevent it from moving out of side arm 4, further enhancing stability. The first baffle 12 limits the position of bottom arm 7 to prevent it from moving out of first stud 11. The rubber pad 17 cushions the PCB board when clamped by clamping plate 15, reducing clamping damage and enhancing practicality.

[0020] Working Principle: When in use, the distance between the two side arms 4 and the top arm 1 can be adjusted by using two sliders 2 and two connecting rods 3, reducing the footprint. Side rods 5 are slidably connected to the bottom of the side arms 4, allowing adjustment of the overall length of the two side arms 4, further reducing the footprint. A first stud 11, threadedly connected to the bottom arm 7, allows the bottom arm 7 to be rotated closer to the top arm 1, further reducing the footprint. All three components—top arm 1, side arms 4, and bottom arm 7—are adjustable, reducing the footprint by 50% when not in use, enhancing practicality. To unfold the device, simply rotate the bottom arm 7 to the bottom of the first stud 11. Then, pull the two side arms 4 to maximize the distance between them and the top arm 1. Guided by the clamp 6 and the slot 8, the two side arms 4 move towards each other, causing the clamp 6 to enter the slot 8. Inside, on the one hand, the position of the bottom arm 7 is limited to prevent it from rotating, and on the other hand, the position of the side rod 5 is limited to prevent it from sliding inside the side arm 4. Finally, by pulling the pull plate 2003 upward, the user can move the locking post 2002 upward, so that the locking post 2002 disengages from the locking hole 24 opened on the top arm 1. At this time, the user can pull the side arm 4 to move it. When it moves to the appropriate position, the locking post 2002 will move downward under the reset thrust of the spring 2004. The locking post 2002 will be inserted into the corresponding locking hole 24 at the top of the top arm 1, locking the position of the slider 2, thereby locking the position of the two side arms 4. By placing the PCB board in the fixing frame 13, the user can rotate the rotating plate 16 to drive the second stud 14 to rotate, so that the clamping plate 15 moves under the limitation of the inner cavity of the fixing frame 13, thereby clamping and fixing the PCB board.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
