[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly defined and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0019] The structure of the fixed carrier mechanism for headphone mini-MIC testing provided by the present invention is as Figure 1 and Figure 4 shown, including a support plate 1. Both the left and right ends of the surface of the support plate 1 are fixed with a carrier assembly 2 by bolts, and an earring product 4 with two positioning grooves at the bottom is placed on the surface of the carrier assembly 2; the carrier assembly 2 is composed of a bearing seat 21, a double-headed probe detection block 22, and a carrier plate 23. The bearing seat 21 is fixedly connected to the surface of the support plate 1 by bolts, and a double-headed probe detection block 22 with two probes at the top is installed on the top of the bearing seat 21 by screws. And a carrier plate 23 is arranged at the top of the double-headed probe detection block 22. Buffer springs 231 are fixed on both sides of the bottom of the carrier plate 23, and the bottom ends of the buffer springs 231 are fixedly connected to the surface of the double-headed probe detection block 22. Limit screws 233 are arranged at the four corner positions of the carrier plate 23, and the bottom ends of the limit screws 233 penetrate through the carrier plate 23 and are threadedly connected to the surface of the double-headed probe detection block 22. The limit screws 233 are used for limiting the up and down movement of the carrier plate 23, and at the same time, the distance between the carrier plate 23 and the double-headed probe detection block 22 can also be adjusted.

[0020] During implementation, the earring product 4 is placed on the surface of the carrier plate 23. When placing it, the positioning groove at the bottom of the earring product 4 is engaged with the positioning block 232 in a mutually positioning manner. After the engagement, the two probes on the surface of the double-headed probe detection block 22 will be aligned with the detection points of the earring product 4. By rotating the limit screw 233 to threadedly connect it with the double-headed probe detection block 22, the distance between the carrier plate 23 and the double-headed probe detection block 22 is adjusted to adjust the contact degree between the two probes of the subsequent double-headed probe detection block 22 and the detection points of the earring product 4.

[0021] Further, as Figure 2 and Figure 3 shown, pressing modules 3 are installed on the left and right side walls of the support plate 1 through bolts. The pressing module 3 is used for the pressing work of the earring product 4. Two groups of positioning blocks 232 are arranged on the surface of the carrier plate 23. The positioning blocks 232 cooperate with the positioning grooves on the surface of the earring product 4 for the clamping and positioning work when the earring product 4 is placed. The pressing module 3 is composed of a mounting plate 31, a pressing cylinder 32, a U-shaped seat 33, a movable arm 34 and a pressing head 35. The mounting plate 31 is fixedly connected to the surface of the support plate 1 through bolts, and a pressing cylinder 32 is fixed to the surface of the mounting plate 31 through screws. One end of the top of the mounting plate 31 is hinged with a movable arm 34 through a hinge rod 311, and a pressing head 35 is inserted and fixed at one end of the top of the movable arm 34. The pressing head 35 is used for the pressing work of the earring product 4. An activity groove 341 is formed at one end of the movable arm 34 away from the pressing head 35. The top of the pressing cylinder 32 is sleeved and fixed with a U-shaped seat 33, and one end of the movable arm 34 located in the activity groove 341 is located inside the U-shaped seat 33. At the same time, a movable rod 331 is arranged on the surface of the U-shaped seat 33, and the movable rod 331 penetrates through the activity groove 341 and extends to the outside of the U-shaped seat 33.

[0022] During implementation, the pressing cylinder 32 on the surface of the mounting plate 31 drives the U-shaped seat 33 to move upward. When moving upward, it will drive the movable arm 34 to rotate around the hinge rod 311 under the activity cooperation of the movable rod 331 and the activity groove 341, so that the pressing head 35 moves downward, thereby pressing the earring product 4. During the pressing, the downward pressing of the carrier plate 23 is buffered by the buffer spring 231, causing the detection points of the earring product 4 to slowly come into contact with the probes on the surface of the double-headed probe detection block 22.

[0023] Working principle: When in use, first place the earring product 4 on the surface of the carrier plate 23. When placing it, the positioning groove at the bottom of the earring product 4 is engaged with the positioning block 232 in a mutually positioning manner. After the engagement, the two probes on the surface of the double-headed probe detection block 22 will be aligned with the detection points of the earring product 4, improving the accuracy of the earring product 4 after placement and avoiding the occurrence of skew phenomena when the earring product 4 is placed.

[0024] Subsequently, by rotating the limit screw 233 to threadedly connect it with the double-headed probe detection block 22, the distance between the carrier plate 23 and the double-headed probe detection block 22 is adjusted to regulate the contact degree between the two probes of the subsequent double-headed probe detection block 22 and the detection points of the earring product 4, so that it can meet the placement work of the detection points at different depths of the earring product 4 as required, thereby expanding the application range of the fixed fixture mechanism.

[0025] Finally, the earring product 4 is pressed down by the pressing module 3. When the pressing module 3 is implemented, the pressing cylinder 32 on the surface of the mounting plate 31 drives the U-shaped seat 33 to move upward. When moving upward, it will drive the movable arm 34 to rotate around the hinge rod 311, and under the active cooperation of the movable rod 331 and the movable groove 341, the pressing head 35 moves downward, thereby pressing down the earring product 4. When pressing down, the buffer spring 231 buffers the downward pressure on the carrier plate 23, causing the detection points of the earring product 4 to slowly come into contact with the probes on the surface of the double-headed probe detection block 22, thus avoiding damage during pressing.
