Description

Technical Field

[0001] The present invention relates to the technical field of tooling and fixtures, and in particular to a testing device. Background Art

[0002] In order to meet the communication and charging needs of wireless headphones with ear handles, a metal contact piece is provided at the bottom of the ear handle of the wireless headphones. When the wireless headphones leave the factory, the metal contact piece is needed to perform a functional test on the wireless headphones.

[0003] In order to improve the user experience and texture of wireless headphones, the bottom of the ear handle of the wireless headphones is generally chamfered smoothly. When the metal contact is set at the bottom of the ear handle, the metal contact also needs to be processed into a curved structure with an arc.

[0004] In the related art, two test probes or springs for accessing the positive and negative electrodes are fixed on the test fixture, and the wireless headset is pushed along the axial direction of the ear handle so that the metal contact on the ear handle contacts the test probe or spring. Since the gap between the two test probes or springs is smaller than the width of the metal contact, as the ear handle moves axially, the metal contact with the curved surface structure will stretch the two test probes or springs apart, increasing the distance between the two test probes or springs. The greater the distance between the two test probes or springs, the greater the deformation of the two test probes or springs, and the greater the pressure applied by the test probes or springs on the metal contacts, so that the elastic force of the test probes or springs can be used to achieve the purpose of stable contact with the metal contacts, and then the wireless headset is stably electrically connected to the test fixture through the metal spring, thereby achieving functional testing of the wireless headset. However, since the surface of the metal contact is a curved surface, during the contact between the metal contact and the test probe or spring, the test probe or spring will exert an axial and normal force on the metal contact along the ear handle, and there is still relative displacement between the two from the beginning of contact until they are fully pressed into place. Therefore, there will be obvious friction force between the metal contact and the test probe or spring. In addition, wireless headphones need to be repeatedly tested at different test stations of the test tooling. When the metal contact contacts and separates from the test probe or spring, the test probe or spring will rub the surface of the metal contact. In this way, the metal contact on the ear handle is easily scratched or scratched, which seriously affects the product quality of the produced wireless headphones. Summary of the invention

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The present invention proposes a testing device for testing the communication function, charging function and other functions of a wireless headset. Figures 1 to 3 As shown, the wireless headset includes an ear handle 61 and a metal contact piece 62 partially arranged on the outer wall of the ear handle 61, and the testing device includes a mounting seat 1, a driving member 3 and at least two test clamps 2, the mounting seat 1 includes a first slide 11 and a second slide 12 which are movably connected, and the first slide 11 is provided with a push block 1221; each test clamp 2 is rotatably connected to the first slide 11 and can be driven to cooperate with the push block 1221; each test clamp 2 is enclosed to form a receiving space 2a for accommodating the ear handle 61; the driving member 3 is connected to the second slide 12, and the driving member 3 drives the second slide 12 to move relative to the first slide 11, so that the push block 1221 drives each test clamp 2 to cooperate and clamp the ear handle 61 located in the receiving space 2a, and makes each test clamp 2 abut against the metal contact piece 62.

[0048] In this embodiment, the mounting base 1 is used to install the test chuck 2. In the mounting base 1, the first slide 11 and the second slide 12 are movably connected by means of rail groove matching, screw rod and screw rod nut matching, etc., and the push block 1221 is connected to the first slide 11 by means of plug-in, screw connection, etc., so that the first slide 11 can move in a directional manner relative to the second slide 12, and drive the push block 1221 to move in a directional manner.

[0049] The test chuck 2 is used to contact the metal contact 62 on the ear handle 61 to form mutual conduction with the metal contact 62. The test chuck 2 can be connected to the test equipment, and the test equipment performs functional testing on the wireless headset through the test chuck 2 and the metal contact 62. Each test chuck 2 is rotatably connected to the first slide 11 by means of hole-shaft matching, hinges, etc. Each test chuck 2 has a free end away from the rotational connection with the first slide 11. When the test chuck 2 rotates relative to the first slide 11, the free ends of each test chuck 2 gather inward or open outward. When the free ends of each test chuck 2 gather inward, they can clamp and fix the ear handle 61 of the wireless headset. Each test chuck 2 is also in transmission cooperation with the push block 1221. For example, the first slide 11 is provided with a hollow boss, and each test chuck 2 is rotatably connected to the outer wall of the boss. The push block 1221 is slidably penetrated into the hollow inner cavity of the boss and is rotatably connected to each test chuck 2 in a hole-shaft cooperation manner. When the push block 1221 moves along the inner cavity of the boss, it drives each test chuck 2 to rotate relative to the first slide 11.

[0050] The metal contact 62 on the ear handle 61 of the wireless headset generally includes two pieces for connecting the positive and negative electrodes of the power supply. The two metal contact pieces 62 are spaced apart on the ear handle 61. Each metal contact piece 62 has a surface exposed on the outer wall of the ear handle 61, and the exposed surface of the metal contact piece 62 is generally large enough to contact the positive / negative electrodes of the power supply. In order to electrically contact the two metal contact pieces 62 to perform a functional test on the wireless headset, the number of test chucks 2 is correspondingly at least two. When the number of test chucks is two, the two test chucks 2 can be arranged in a mirror-symmetrical manner. The mirror-symmetrical arrangement includes two test chucks 2 arranged in parallel and opposite to each other, as well as Figure 2 The two test chucks 2 shown are arranged at an angle. Based on the fact that each metal contact piece 62 has a sufficiently large surface area, the relative position and angle of the two test chucks 2 can be flexibly designed, as long as the two test chucks 2 can respectively contact and conduct with the two metal contact pieces 62 during the wireless headset test. When there are multiple test chucks 2, each test chuck 2 can be arranged in a ring-shaped surrounding manner. During the wireless headset test, some test chucks 2 contact one metal contact piece 62, and the remaining test chucks 2 contact another metal contact piece 62.

[0051] The driving member 3 is used to drive the second slide 12 to move relative to the first slide 11. The driving member 3 can be arranged on the first slide 11 or connected and fixed to the first slide 11 through an intermediate connecting member. The driving member 3 can be a cylinder, a linear motor, etc., so that the driving member 3 can drive the second slide 12 to move relative to the first slide 11 in a directional manner.

[0052] In this embodiment, at least two rotatable test chucks 2 are arranged on the first slide 11, and the second slide 12 movably connected to the first slide 11 is driven to move by the driving member 3, so that when the second slide 12 moves, it drives the push block 1221 arranged on the second slide 12 to move, so that the push block 1221 drives the free ends of each test chuck 2 that cooperates with it to close inward or open outward, so that each test chuck 2 can cooperate with the clamping ear handle 61 when closing inward, and the test chuck 2 contacts the metal contact sheet 62 on the ear handle 61, and then the wireless headset can be functionally tested through the test chuck 2 and the metal contact sheet 62. After the wireless headset test is completed, the driving member 3 runs in reverse to drive the push block 1221 to drive the free ends of each test chuck 2 to open outward, and the headset that has completed the test can be taken out. In the above process, the free end of each test chuck 2 moves from the radial direction of the ear handle 61 toward (during testing) or away from (after the test is completed), and there is no relative movement between the metal contact piece 62 on the ear handle 61 and the test chuck 2 along the axial direction of the ear handle 61. After the test chuck 2 contacts the metal contact piece 62, there is no relative displacement of the metal contact piece 62, which basically avoids the scratching and friction of the test chuck 2 on the metal contact piece 62, greatly reduces the risk of the metal contact piece 62 being scratched during the test process, and improves the reliability of the wireless headset test and the product quality of the wireless headset when leaving the factory.

[0053] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the first slide seat 11 is provided with a mounting portion 111, and each test chuck 2 is rotatably connected to the mounting portion 111; a guide groove 111a is provided in the mounting portion 111, and an opening 111b communicating with the outside is provided on the side wall of the guide groove 111a corresponding to the test chuck 2, and one end of each test chuck 2 extends into the guide groove 111a through the opening 111b; at least part of the structure of the push block 1221 is slidably limited in the guide groove 111a, and the push block 1221 can contact the test chuck 2 when moving along the guide groove 111a, and drive the test chuck 2 to rotate relative to the mounting portion 111.

[0054] In this embodiment, the mounting portion 111 is a boss structure on the first slide 11, and a guide groove 111a is provided in the mounting portion 111, which is connected to the outside and arranged along the moving direction of the second slide 12. The push block 1221 passes through the notch of the guide groove 111a and extends into the guide groove 111a, and slides and abuts or loosely fits with the inner wall of the guide groove 111a. The side wall of the guide groove 111a is provided with an opening 111b that passes through the outer wall of the mounting portion 111, and the rotation connection between the test chuck 2 and the mounting portion 111 is located in or adjacent to the opening 111b. In the non-testing state, one end of the test chuck 2 passes through the opening 111b and extends into the guide groove 111a, and the push block 1221 is disengaged from the test chuck 2; in the testing state, the push block 1221 is driven by the driving member 3 to move along the guide groove 111a and contact the end of the test chuck 2 extending into the guide groove 111a, and the push block 1221 squeezes and pushes the end of the test chuck 2 extending into the guide groove 111a, and the test chuck 2 rotates relative to the mounting portion 111, so that the free ends of each test chuck 2 away from the opening 111b gather inward and cooperate with the clamping ear handle 61. In this way, the present embodiment utilizes the lever principle to enable the push block 1221 to push one end of the test chuck 2 to move, and drives the free end of the test chuck 2 to move, thereby cleverly realizing the drive control of each test chuck 2. Moreover, a detachable transmission cooperation mode is adopted between the push block 1221 and each test chuck 2. The push block 1221 and each test chuck 2 are neither directly connected nor connected through a transmission member, which can simplify the structure of the present test device, avoid the use of intermediate transmission members, reduce the volume of the present test device, and reduce the manufacturing cost of the present test device.

[0055] Alternatively, if Figure 4 As shown, the push block 1221 may be a wedge-shaped structure, and its outer wall has two inclined surfaces arranged opposite to each other. The shape of the guide groove 111a is adapted to the outer shape of the push block 1221, and the guide groove 111a also has two side walls arranged in an inclined surface. The two inclined surfaces of the push block 1221 are respectively in sliding contact with the two inclined side walls of the guide groove 111a to realize the movement guidance of the push block 1221 in the guide groove 111a, thereby ensuring the stability of the movement of the push block 1221. The above-mentioned openings 111b are provided on the two inclined side walls of the guide groove 111a, and the number of the test chucks 2 is two, and the two test chucks 2 are respectively located at the two openings 111b, and one end of each test chuck 2 passes through an opening 111b and extends into the guide groove 111a. When the push block 1221 moves along the guide groove 111a, the two inclined surfaces of the push block 1221 respectively abut against one end of the two test clamps 2 extending into the guide groove 111a, and simultaneously drive the two test clamps 2 to rotate relative to the mounting portion 111, so that the free ends of the two test clamps 2 cooperate to clamp the ear handle 61 of the wireless headset to be tested. In this way, the two test clamps 2 can be driven stably and reliably by a single push block 1221.

[0056] In one embodiment of the present invention, Figure 4 As shown, the outer wall of the mounting portion 111 is provided with at least two first elastic members 112, each 112 is connected to a test chuck 2, and the first elastic member 112 applies an elastic force to one end of the test chuck 2 in a direction away from the mounting portion 111, so that the other end of the test chuck 2 passes through the opening 111b and extends into the guide groove 111a.

[0057] In this embodiment, the end of the test chuck 2 away from the test chuck 2 extending into the guide groove 111a is a free end, and the first elastic member 112 is disposed between the free end of the test chuck 2 and the mounting portion 111, and is connected to the test chuck 2 and the mounting portion 111 by abutting or by hole limiting. The rotational connection between the test chuck 2 and the mounting portion 111 is located between the first elastic member 112 and the end of the test chuck 2 extending into the guide groove 111a. The first elastic member 112 applies an elastic force to the free end of the test chuck 2, so that the free end of the test chuck 2 is away from the mounting portion 111, and the end of the test chuck 2 away from the free end passes through the opening 111b and extends into the guide groove 111a, so that the test chuck 2 is tilted as a whole, and the free ends of each test chuck 2 are opened to form a larger accommodating space 2a for the ear handle 61 to freely enter and exit. Thus, when the ear handle 61 is inserted into the accommodating space 2a formed by the free ends of the test chucks 2, the outer wall of the ear handle 61 and the metal contact sheet 62 will not rub against the free ends of the test chucks 2, which can effectively prevent the ear handle 61 and the metal contact sheet 62 from being scratched. The first elastic member 112 can be a metal spring, a rubber spring, etc.

[0058] When the ear handle 61 is placed in the accommodating space 2a, the driving member 3 drives the second slide 12 to drive the push block 1221 to move into the guide groove 111a, and the push block 1221 pushes one end of each test clamp 2 to extend into the guide groove 111a, so that each test clamp 2 rotates relative to the mounting seat 1, and each test clamp 2 squeezes the first elastic member 112 located between it and the mounting portion 111, and the free ends of each test clamp 2 approach each other and gather inward, and the free ends of each test clamp 2 cooperate to clamp the ear handle 61, and each test clamp 2 contacts and conducts with the metal contact 62 on the ear handle 61, so as to realize the functional test of the wireless headset through the test clamp 2 and the metal contact 62. When the wireless headset test is completed, the driving member 3 drives the second slide 12 to drive the push block 1221 to move toward the outside of the wire groove, and the push block 1221 gradually disengages from the end of the test clamp 2. The free end of the test clamp 2 moves away from the mounting portion 111 under the elastic action of the first elastic member 112. The free ends of each test clamp 2 move away from each other and open outward. The ear handle 61 of each test clamp 2 moves in the radial direction and disengages from the ear handle 61. In this way, the tested wireless headset located in the accommodating space 2a can be freely taken out, and the test clamp 2 will not actively scratch the ear handle 61 or the metal contact sheet 62.

[0059] In one embodiment of the present invention, Figure 4 As shown, the outer wall of the mounting portion 111 is provided with at least two limiting grooves 111c, which are arranged along the length direction of the test chuck 2, and a part of the structure of each test chuck 2 is limited in the limiting groove 111c.

[0060] In this embodiment, the limiting groove 111c is used to limit the test chuck 2. The limiting groove 111c is a groove structure opened on the outer wall of the mounting portion 111. The limiting groove 111c is extended along the length direction of the test chuck 2, and accommodates and limits a part of the structure of the test chuck 2. The limiting groove 111c can also be connected with the opening 111b. In this way, the side wall of the limiting groove 111c will stop and limit the upper and lower ends of the test chuck 2 to prevent the test chuck 2 from moving up and down during the rotation process, ensure the reliability of each test chuck 2 when clamping the ear handle 61, and enable the test chuck 2 to accurately contact the metal contact sheet 62 on the ear handle 61.

[0061] In one embodiment of the present invention, Figure 4 As shown, at least two rotating shafts 113 are penetrated through the side wall of the opening 111 b , and each test chuck 2 is provided with an axial hole, and each rotating shaft 113 passes through an axial hole.

[0062] In this embodiment, the inner wall of the opening 111b can extend outward to form an extension portion, and the rotating shaft 113 can be inserted through the extension portion and located between the extension portion and the outer wall of the first slide seat 11; or, the two ends of the rotating shaft 113 are respectively inserted through the opposite side walls of the opening 111b. The test chuck 2 is rotatably connected to the mounting portion 111 through the hole-shaft fit between the rotating shaft 113 and the shaft hole. In this way, the rotational connection between the test chuck 2 and the mounting part is located in the opening 111b, and the distance between the free end of the test chuck 2 and the rotational connection is greater than the distance between the end of the test chuck 2 away from its free end and the rotational connection, and the end of the test chuck 2 away from its free end is the force-applying end of the push block 1221, so that the test chuck 2 as a whole becomes a force-consuming lever structure, and the smaller movement of the end of the test chuck 2 away from its free end can be converted into a larger movement of the free end of the test chuck 2, which is conducive to shortening the moving distance of the end of the push block 1221 that pushes the test chuck 2 to extend into the guide groove 111a, reducing the moving stroke of the push block 1221, and helping to compress the volume of the test device. In addition, the free end of the test chuck 2 with a larger displacement amplitude can also achieve a more reliable clamping of the ear handle 61, and improve the reliability of the abutment between the test chuck 2 and the metal contact sheet 62.

[0063] In one embodiment of the present invention, Figure 4 and Figure 5As shown, one end of each of the test chucks 2 extending into the guide groove 111a is provided with a guide wall 211 and a limiting wall 212 connected to each other; when the push block 1221 moves in the guide groove 111a, it can move along the guide wall 211 and drive each of the test chucks 2 to rotate relative to the mounting portion 111; when each of the test chucks 2 cooperates with the clamping ear handle 61, the push block 1221 abuts against the limiting wall 212 of each of the test chucks 2 to limit the position.

[0064] In this embodiment, the guide wall 211 and the limiting wall 212 are both located on the side of the test chuck 2 facing the push block 1221, wherein the guide wall 211 is an inclined surface, which is arranged at an angle with the length direction of the test chuck 2; the limiting wall 212 is a plane, which is arranged parallel to the length direction of the test chuck 2. When the push block 1221 moves into the guide groove 111a, the outer wall of the push block 1221 slides against the guide wall 211, and the end of the push block 1221 close to the test chuck 2 slides along the guide wall 211 and pushes the test chuck 2 to rotate relative to the mounting portion 111, and the test chuck 2 squeezes the first elastic member 112, and the free ends of each test chuck 2 approach each other until the end of the push block 1221 close to the test chuck 2 slides along the guide wall 211 to the limiting wall 212, and the free ends of each test chuck 2 move to the limit position and cooperate to clamp the ear handle 61 of the wireless headset to be tested. When the wireless headset test is completed, the push block 1221 moves outward from the guide groove 111a, and the push block 1221 slides along the limit arm to the guide wall 211. The free ends of the test chuck 2 move away from each other under the elastic action of the first elastic member 112 and release the ear handle 61 of the wireless headset; in this way, the drive control of the test chuck 2 and the testing and loading and unloading of the wireless headset are realized.

[0065] In one embodiment of the present invention, Figures 1 to 4 As shown, the above-mentioned testing device also includes a base 4 and a positioning seat 5, the positioning seat 5 and the driving member 3 are arranged on the base 4, and the positioning seat 5 is used to position the wireless headset; the second slide 12 is movably connected to the base 4, and can move close to or away from the positioning seat 5, the second slide 12 is provided with a bearing portion 121 and a stop portion 122 arranged at an angle, and the push block 1221 is arranged on the stop portion 122; the first slide 11 is movably arranged on the bearing portion 121, and is located between the stop portion 122 and the positioning seat 5; when each test chuck 2 clamps the ear handle 61, the first slide 11 abuts against the positioning seat 5 to limit the position.

[0066] In this embodiment, the base 4 is used to install the positioning seat 5 and the second slide 12. The positioning seat 5 is used to position the wireless headset to be tested. The positioning seat 5 may be provided with a buckle structure for clamping and fixing the wireless headset. The second slide 12 may be movably connected to the base 4 by means of rail groove matching, screw rod and screw rod nut matching, etc. The second slide 12 can be driven by the driving member 3 to move closer to or away from the positioning seat 5 relative to the base 4, so that the test chuck 2 on the first slide 11 moves closer to or away from the wireless headset on the positioning seat 5. The first slide 11 may be movably connected to the bearing portion 121 by means of rail groove matching, etc. When the second slide 12 is driven to move, the first slide 11 moves with the second slide 12.

[0067] When performing a functional test on the wireless headset on the positioning seat 5, the driving member 3 drives the second slide 12 to drive the first slide 11 to move toward the positioning seat 5. At this time, part of the structure of the first slide 11 protrudes from the side of the second slide 12 facing the positioning seat 5, and the push block 1221 disengages from the test clamp 2 until the first slide 11 abuts against the positioning seat 5, and the ear handle 61 of the wireless headset is located in the accommodating space 2a formed by the opened multiple test clamps 2. At this time, the driving member 3 continues to drive the second slide 12 to move closer to the positioning seat 5, and the push head of the second slide 12 moves toward the guide groove 111a of the first slide 11. The push head drives each test clamp 2 to rotate relative to the mounting portion 111, and the free ends of each test clamp 2 gather inward and clamp the ear handle 61, and the test clamp 2 contacts and conducts with the metal contact 62 on the ear handle 61.

[0068] In one embodiment of the present invention, Figures 4 to 6 As shown, a first positioning groove 121a is provided on the side of the bearing portion 121 facing the first slide 11, and a second positioning groove 11a connected to the first positioning groove 121a is provided on the side of the first slide 11 facing the bearing portion 121; the testing device also includes a second elastic member 13, a part of the structure of the second elastic member 13 is located in the first positioning groove 121a, and the rest of the structure of the second elastic member 13 is located in the second positioning groove 11a; when each test chuck 2 clamps the ear handle 61, the second elastic member 13 applies an elastic force to the first slide 11 in the direction of the positioning seat 5.

[0069] In this embodiment, if Figure 5 As shown, before testing the wireless headset, the second elastic member 13 is located in the space enclosed by the first positioning groove 121a and the second positioning groove 11a and is in a non-compressed state, the free end of each test clamp 2 is opened outward under the elastic action of the first elastic member 112, and the end of each test clamp 2 away from its free end extends into the guide groove 111a, the push block 1221 is located in the guide groove 111a and is disengaged from the end of each test clamp 2 extending into the guide groove 111a, and part of the structure of the first slide seat 11 protrudes from the side of the second slide seat 12 facing the positioning seat 5.

[0070] like Figure 6 As shown, when the wireless headset is tested, the wireless headset to be tested is placed on the positioning seat 5 for positioning, and the driving member 3 drives the second slide 12 to drive the first slide 11 to move close to the positioning, and the first slide 11 first abuts against the positioning seat 5 and will not continue to move. At this time, the ear handle 61 of the wireless headset to be tested is located in the accommodating space 2a enclosed by the opened test clamps 2; the second slide 12 continues to move under the drive of the driving member 3, and drives the push block 1221 to move into the guide groove 111a, and the push block 1221 slides along the guide wall 211 of each test clamp 2 to the limit wall 212, and each test clamp 2 rotates relative to the mounting portion 111, and the free end of each test clamp 2 gathers inward and clamps the ear handle 61 located in the accommodating space 2a, and each test clamp 2 contacts and conducts with the metal contact sheet 62 on the ear handle 61, and the wireless headset is functionally tested through the test clamp 2 and the metal contact sheet 62. At this time, because the first positioning groove 121a and the second positioning groove 11a are offset from each other, the second elastic member 13 is compressed by the side walls of the first positioning groove 121a and the second positioning groove 11a, and the second elastic member 13 applies an elastic force on the first sliding seat 11 toward the positioning seat 5.

[0071] After the wireless headset test is completed, the driving member 3 reversely drives the second slide 12 to drive the push block 1221 to move outward from the guide groove 111a, and each test chuck 2 is reset under the action of the corresponding first elastic member 112, and the free end of each test chuck 2 opens outward and separates from the metal contact piece 62 on the ear handle 61. The first slide 11 is still pressed against the positioning seat 5 under the elastic action of the second elastic member 13 and does not move with the movement of the second slide 12, until the second elastic member 13 elastically restores the initial state, and the second elastic member 13 no longer applies an elastic force toward the positioning seat 5 to the first slide 11, the second slide 12 will drive the first slide 11 to retract and reset through the second elastic member 13, and each test chuck 2 will also reset accordingly. In this way, after the wireless headset test is completed, the present embodiment can first open each test chuck 2 to release the tested wireless headset and then retract it, and the test chuck 2 will not retract in the state of clamping the wireless headset, which can prevent the test chuck 2 from causing damage to the ear handle 61 and the metal contact piece 62 of the wireless headset. The second elastic member 13 may be a metal spring, a rubber spring or the like.

[0072] In one embodiment of the present invention, Figure 2 and Figure 4As shown, one of the two sides of the above-mentioned bearing portion 121 facing the first slide 11 and the side of the first slide 11 facing the bearing portion 121 is provided with a positioning column 1213, and the other of the two sides of the bearing portion 121 facing the first slide 11 and the side of the first slide 11 facing the bearing portion 121 is provided with a bar hole 11b, the bar hole 11b is arranged along the moving direction of the first slide 11, and the positioning column 1213 is slidably limited in the bar hole 11b; and / or, one of the two sides of the stop portion 122 facing the first slide 11 and the side of the first slide 11 facing the stop portion 122 is provided with a positioning pin 1222, and the other of the two sides of the stop portion 122 facing the first slide 11 and the side of the first slide 11 facing the stop portion 122 is provided with a positioning hole 11c, the positioning hole 11c is arranged along the moving direction of the first slide 11, and the positioning pin 1222 is slidably limited in the bar hole 11b.

[0073] In this embodiment, the arrangement of the positioning column 1213 and the bar hole 11b can cooperate to guide the movement of the first slide 11 on the bearing portion 121 of the second slide 12, thereby improving the stability and reliability of the relative movement of the first slide 11 and the second slide 12. The arrangement of the positioning pin 1222 and the positioning hole 11c can also cooperate to guide the movement of the first slide 11 on the bearing portion 121 of the second slide 12, thereby improving the stability and reliability of the relative movement of the first slide 11 and the second slide 12. The positioning column 1213 and the bar hole 11b can cooperate to limit the first slide 11 in the horizontal direction, and the positioning pin 1222 and the positioning hole 11c can cooperate to limit the first slide 11 in the vertical direction. When the positioning column 1213, the bar hole 11b, the positioning pin 1222 and the positioning hole 11c are set at the same time, the first slide 11 can be limited in the horizontal and vertical directions to avoid shaking or vibration when the first slide 11 moves relative to the second slide 12, thereby ensuring the movement stability of the first slide 11 and improving the reliability of the test device when testing wireless headphones.
