[0017] Preferably, the finger ring is sleeved on the pressing block, and the circumference of the finger ring is adjustable, wherein the width of the finger ring is the same as the width of the bottom surface of the pressing block groove.

[0018] Preferably, the finger ring includes an elastic part and a connecting part, the elastic part is located on the top of the top surface of the pressing block, the connecting part is located on both sides of the pressing block and the bottom surface of the opening, and the connecting part includes a Velcro at the connection of the finger ring.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] An embodiment of the present application discloses a detector auxiliary installation fixture.

[0030] Reference Figure 1 、 Figure 3 and Figure 4 , a detector auxiliary installation fixture, when in use, align the pin of the detector 4 with the tooling board 3 with one hand, and fix the operator's finger on the top of the pressing block 1 in the auxiliary installation fixture through the finger ring 2, and straddle the limit block 13 on both sides of the detector 4 PCB board. Press down the top surface of the pressing block 1 with the finger force, where the groove 11 on the bottom surface of the pressing block 1 can accommodate the PD chip, lead and protective glue, and the pressure feet 12 on both sides of the opening of the groove 11 can press the detector 4 PCB board, pressing the pin of the detector 4 into the needle seat hole of the tooling board 3.

[0031] Reference Figure 1 The opening width of the groove 11 at the bottom of the pressing block 1 is larger than the bottom width of the groove 11. The design of the opening of the groove 11 being larger than the bottom makes the main structure of the pressing block 1 more stable and less likely to deform when pressed. An arc-shaped transition 111 is used between the opening of the groove 11 and the pressure foot 12. The arc-shaped transition 111 ensures that even if there is a certain degree of deviation when the pressure foot 12 presses the detector 4 PCB board, it is not easy to damage the PD chip, leads, and protective adhesive of the detector 4.

[0032] Reference Figure 1The surface of the presser foot 12 and the inner side of the limit block 13 are coated with an insulating buffer layer 121. The insulating buffer layer 121 can effectively buffer the impact of the limit block 13 on the PCB board of the detector 4, reducing the damage to the detector 4.

[0033] Reference Figure 1 The free end of the stopper 13 is provided with a guide angle 131, which is an arc-shaped surface located at the bottom of the stopper 13. The arc-shaped guide angle 131 of the stopper 13 not only guides the auxiliary installation fixture of the detector 4 into the inner side of the needle seat, but also prevents the pressing block 1 from colliding with the PD chip, leads, and protective adhesive when installing it onto the detector 4, thereby damaging the detector 4.

[0034] Reference Figure 1 The arc-shaped protrusions 14 are provided on both outer sides of the groove 11 of the pressing block 1, wherein the arc-shaped protrusions 14 are arranged at the connection between the top surface and the side surface, and the arc-shaped protrusions 14 protrude from the side surface of the pressing block 1. The arc-shaped protrusions 14 are provided at the connection between the top surface and the side surface of the pressing block 1, which can make the operator's fingers more comfortable when pressing the top surface, and when the finger ring 2 is lost or damaged, the pressing block 1 can also be taken out by holding the arc-shaped protrusions 14 on both sides of the pressing block 1.

[0035] Reference Figure 1 and Figure 2 The finger ring 2 is mounted on the pressing block 1, and the circumference of the finger ring 2 is adjustable, wherein the width of the finger ring 2 is the same as the width of the bottom surface of the groove 11 of the pressing block 1. The finger ring 2 includes an elastic portion 21 and a connecting portion 22, wherein the elastic portion 21 is located at the top of the top surface of the pressing block 1, and the connecting portion 22 is located on both sides of the pressing block 1 and the bottom surface of the opening, and the connecting portion 22 includes a Velcro connection at the connection of the finger ring 2. The connecting portion 22 in the finger ring 2 uses a Velcro structure to adjust the circumference of the finger ring 2 by connecting the hook surface at one end with the velvet surface at the other end at different positions, thereby adapting to the fingers of different operators, and the elastic portion 21 on the finger ring 2 can stably connect the finger to the pressing block 1.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
