[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1 As shown, a dipping tool for processing ball pins includes a circular ring bracket 1, a connecting hole 2, a support panel 3, and a column 5.

[0025] There are at least three columns 5 between the circular brackets 1, which are welded and fixed to the circular brackets. Six support panels 3 are connected to the circular brackets 1. Each support panel 3 has several connection holes 2, and the ball pins can be hung in the connection holes 2.

[0026] In this utility model, six support panels are spot-welded to the circular bracket 1. After spot welding, the support panels 3 are fixed. Furthermore, the support panels 3 can be replaced by melting the tin liquid. The size and gap of the connection holes 2 in the support panels 3 can be punched based on the actual size of the ball pins. After punching, the holes can be connected to the same circular bracket. This allows the circular bracket 1 to be dip-coated with multiple ball pins simultaneously, making it more economical and practical.

[0027] In the present utility model, Figure 1 The figure shows a combination of two circular ring brackets 1. In actual production, multiple layers can be connected, not limited to two layers.

[0028] like Figure 2 As shown, the ring bracket 1 includes a large ring 11, a small ring 12, and fixing rods 13. The large ring 11 and the small ring 12 are coaxial and on the same plane. Six fixing rods 13 are welded between the large ring 11 and the small ring 12, and the ends of the fixing rods 13 are respectively against the inside of the large ring 11 and the outside of the small ring 12.

[0029] In the present invention, the large circular ring 11, the small circular ring 12 and the fixing rod 13 are welded together, so as to be more solid and stable.

[0030] like Figure 1 As shown, the longer arc side of the support panel 3 is connected to the large circular ring 11 , the shorter arc side of the support panel 3 is connected to the small circular ring 12 , and the side edge of the support panel 3 is connected to the fixing rod 13 .

[0031] In the present invention, the closed plane formed by the large ring 11, the small ring 12 and the fixing rod 13 can just accommodate the support panel 3. After spot welding the support panel 3, the fixing rod 13 also serves as a reinforcing rib, which can prevent the support panel 3 from large-scale deformation after the ball pin is placed.

[0032] like Figure 3 As shown, the column 5 includes an inner shaft 51, an outer shaft 52, a first connecting member 53 and a second connecting member 54. The inner shaft 51 is sleeved inside the outer shaft 52, and the inner shaft 51 can slide inside the outer shaft 52. The second connecting member 54 is threadedly connected to the outer side of the first connecting member 53.

[0033] In the present invention, when the first connecting member 53 and the second connecting member 54 are not locked at all, the inner shaft 51 can slide up and down in the outer shaft 52. When the inner shaft 51 and the outer shaft 52 slide to the required length, by tightening the second connecting member 54, the inner shaft 51 and the outer shaft 52 can be ensured not to slide relative to each other.

[0034] like Figure 4 As shown, the first connecting member 53 includes a pressing shaft 531 and a connecting shaft 532. The inner diameter of the connecting shaft 532 is larger than that of the pressing shaft 531. The pressing shaft 531 is sleeved on the inner shaft 51, and the connecting shaft 532 is sleeved on the outer shaft 52.

[0035] like Figure 3 、 Figure 4 As shown, a groove 5311 is provided on the clamping shaft 531 , and after the second connecting member 54 is locked, the clamping shaft 531 can be fixedly connected to the inner shaft 51 .

[0036] In the present invention, the inner diameter of one slotted end of the compression shaft 531 is slightly larger than the inner diameter of the other end of the compression shaft 531. After the second connector is tightened, the gap between the slots 5311 is reduced to be almost the same as the inner diameter of the other end of the compression shaft 531. At this point, the compression shaft 531 squeezes the inner shaft 51 to achieve an interference fit, thereby securely connecting the inner shaft 51 to the outer shaft 52.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
