Description

Technical Field

[0001] This utility model relates to the field of film and television equipment technology, and in particular to a testing device. Background Technology

[0002] In the photography industry, film and television accessories are crucial for shooting. Among them, lighting equipment is the key device for shaping light, while tripods, stabilizers, and other auxiliary equipment provide support for the camera and usually need to be securely connected to the support. The handle on the support serves as an important control component, allowing the film and television accessories to rotate flexibly around the support, thereby adjusting the lighting angle of the lighting equipment or changing the shooting angle of the camera, helping the photographer achieve diverse shooting effects.

[0003] However, during prolonged and frequent use, the handle will inevitably experience wear and tear, loose parts, and button malfunctions. These potential problems, once they occur, will directly affect the handle's control over lighting or photographic equipment, leading to inaccurate shooting angle adjustments.

[0004] Currently, the testing of handles generally adopts a manual operation method. This means that testers need to simulate the rotation of the handle in various real-world usage scenarios, including different rotation angles, speeds, and forces. This requires testers to perform a large number of repetitive actions, and each handle must undergo multiple rotation tests. The whole process is very tedious, time-consuming, and labor-intensive, which greatly reduces testing efficiency. Utility Model Content

[0005] In order to overcome at least one of the defects described in the prior art, the present invention provides a testing device that can improve the testing efficiency of handles.

[0006] The technical solution adopted by this utility model to solve its problem is: A testing apparatus for performing a rotation test on the handle of a device under test, comprising: Test bench; A connecting base is movably disposed on the test bench and can move along a first direction, and the device under test is fixedly installed on the connecting base; A test assembly is mounted on the test bench. The test assembly includes an adjustment base, a clamping mechanism, and a driving component. The adjustment base is disposed opposite to the connecting base. The clamping mechanism is rotatably mounted on the adjusting seat, the driving member is used to drive the clamping mechanism to rotate, and the clamping mechanism is used to clamp the handle.

[0007] Furthermore, the test bench is provided with a first slide rail, which extends along the first direction, and the connecting seat is provided with a first slider, which slides in cooperation with the first slide rail to drive the connecting seat to move along the first direction.

[0008] Furthermore, the test platform is provided with a second slide rail, which extends along a second direction perpendicular to the first direction. The bottom of the adjustment seat is provided with a second slider, which slides in cooperation with the second slide rail to drive the test component to move along the second direction.

[0009] Furthermore, the adjusting base is provided with a mounting base and an adjusting assembly; The adjustment assembly includes an adjustment rod, an adjustment nut, and an adjustment plate. One end of the adjustment plate is connected to the adjustment nut, and the other end of the adjustment plate is connected to the mounting base. The adjusting rod extends along a third direction perpendicular to the first and second directions. The adjusting nut is threadedly engaged with the adjusting rod. When the adjusting rod rotates, the adjusting nut moves along the third direction, causing the adjusting plate to move along the third direction, thereby causing the mounting base to move along the third direction.

[0010] Furthermore, the adjusting seat is provided with a third slide rail, which extends along the third direction, and the mounting seat is provided with a third slider, which slides in cooperation with the third slide rail to drive the mounting seat to move along the third direction.

[0011] Furthermore, the adjusting rod is also provided with a handle, which is located at the end of the adjusting rod away from the test platform. Rotating the handle will cause the adjusting rod to rotate.

[0012] Furthermore, the clamping mechanism includes a first clamping block, a second clamping block, and a mounting plate. The first clamping block and the second clamping block are spaced apart on the mounting plate. When force is applied, the first clamping block and / or the second clamping block move closer to or further away from each other to clamp or release the handle. The driving member is connected to the mounting plate and drives the mounting plate to rotate.

[0013] Furthermore, the clamping mechanism also includes a locking rod and a locking member. One end of the locking rod is fixed to the second clamping block, and the other end of the locking rod passes through the first clamping block. The locking member is installed on the first clamping block and connected to the locking rod to lock or release the first clamping block.

[0014] Furthermore, the clamping mechanism also includes at least two guide rods, one end of each of the two guide rods is fixed to the second clamping block, and the other end of each of the two guide rods passes through the first clamping block, allowing the first clamping block to move upward along the guide rods in the third direction.

[0015] Furthermore, the test stand is provided with two locking components, which are respectively connected to the connecting seat and the adjusting seat; The locking component includes a latch and a locking rod. One end of the latch is connected to the connecting seat or adjusting seat, and the other end of the latch is rotatably connected to the locking rod. The latch is used to drive the locking rod to move up and down along its own axis when rotated, so as to lock or unlock the connecting seat or adjusting seat.

[0016] In summary, the testing device provided by this utility model has the following technical effects: it installs the device under test on the connecting seat, and then the connecting seat moves closer to the adjusting seat along the first direction until the clamping mechanism can clamp the handle of the device under test. Then, the clamping mechanism is driven to rotate by the driving component, thereby driving the handle to rotate repeatedly to perform testing. The entire testing process does not require manual intervention, saving time and effort and improving testing efficiency. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figures 1 to 6 This utility model discloses a testing device for performing rotation tests on the handle 2 of the device under test 1. It includes a test platform 10, a connecting seat 20, and a testing component 3. The connecting seat 20 is movably disposed on the test platform 10 and can move along a first direction. The device under test 1 is fixedly installed on the connecting seat 20. The testing component 3 is installed on the test platform 10. The testing component 3 specifically includes an adjusting seat 30, a clamping mechanism 40, and a driving component 50. The adjusting seat 30 is disposed opposite to the connecting seat 20. The clamping mechanism 40 is rotatably installed on the adjusting seat 30. The clamping mechanism 40 is used to clamp the handle 2, and the driving component 50 is used to drive the clamping mechanism 40 to rotate.

[0027] Based on the above structure, taking the length direction of the test platform 10 as an example, during assembly, the connecting seat 20 is positioned to correspond to the clamping mechanism 40 on the adjusting seat 30. This ensures that after the device under test (DUT) 1 is installed with the connecting seat 20, the handle 2 on the DUT 1 can be aligned with the clamping mechanism 40 for easy clamping. When the testing device is in its initial state, the connecting seat 20 is positioned away from the adjusting seat 30, creating a gap. This prevents the operator from easily colliding with the clamping mechanism 40 or other structures on the adjusting seat 30 when connecting the DUT 1 (such as a bracket for audio-visual equipment or accessories) with the handle 2 to the connecting seat 20. This allows for more open space around the DUT 1, making it easier for the operator to install the DUT 1. It also avoids problems such as improper installation or incorrect installation direction due to limited space, resulting in smoother operation.

[0028] After the device under test 1 with handle 2 is installed on the connector 20, the handle 2 is aligned with the position of the clamping mechanism 40. At this time, the operator can manipulate the connector 20 to move it closer to the adjusting seat 30 in the first direction until the connector 20 and the adjusting seat 30 reach a suitable position. Then, the clamping mechanism 40 on the adjusting seat 30 clamps the handle 2. After clamping is completed, the drive unit 50 is activated to drive the clamping mechanism 40 to rotate. During the rotation, the clamping mechanism 40 can synchronously drive the handle 2 to rotate continuously and reciprocally, simulating various operating scenarios of the handle 2 in actual use, and testing the handle 2.

[0029] Once the test is complete, simply detach the handle 2 from the clamping mechanism 40, and then manipulate the connecting seat 20 to move away from the adjusting seat 30 in the first direction until the distance between the connecting seat 20 and the adjusting seat 30 is appropriate. In a relatively open space, the equipment on the connecting seat 20 can be easily removed, a new device under test 1 can be replaced, and the next round of cyclic testing can begin. The entire testing process does not require manual intervention, saving time and effort and greatly improving testing efficiency.

[0030] It should be noted that in this embodiment, the connecting seat 20 can be connected to the test bench 10 by a sliding connection. For example, a linear guide rail is installed on the test bench 10, extending along a first direction. Simultaneously, a slider or pulley matching the linear guide rail is installed at the bottom of the connecting seat 20, allowing the slider or pulley to slide in contact with the linear guide rail. When an external force is applied to the connecting seat 20, the slider slides on the linear guide rail, causing the connecting seat 20 to move linearly along the direction of the linear guide rail, thereby moving closer to or further away from the adjusting seat 30.

[0031] Alternatively, the connecting seat 20 and the test bench 10 can be connected via a lead screw and nut transmission. For example, a lead screw is installed on the test bench 10, extending along a first direction, and a lead screw nut with a threaded fit is installed on the connecting seat 20. In use, the operator can rotate it manually or drive the lead screw to rotate via a motor. The nut will move linearly along the axis of the lead screw under the helical action of the lead screw, thereby moving the connecting seat 20 closer to or away from the adjusting seat 30.

[0032] Of course, the connection between the connecting seat 20 and the test bench 10 can also be achieved through a rack and pinion transmission connection. For example, a rack can be installed on the test bench 10 along the movement direction of the connecting seat 20 (i.e., the first direction), and a gear that meshes with the rack can be installed on the connecting seat 20. The gear is usually connected to the motor through a shaft. When the motor drives the gear to rotate, the rotational motion of the gear is converted into the linear motion of the rack due to the meshing of the gear and the rack, thereby driving the connecting seat 20 to move linearly closer to or away from the adjusting seat 30 along the first direction. The specific connection method between the connecting seat 20 and the test bench 10 can be set according to the actual scenario requirements, and will not be elaborated here.

[0033] More specifically, in this embodiment, limiters 14 are respectively provided at both ends of the test bench 10. The two limiters 14 are spaced apart along the first direction and abut against the connecting seat 20 when the connecting seat 20 moves to the end of its stroke along the first direction. When the connecting seat 20 moves along the first direction to abut against one of the limiters 14, the connecting seat 20 is blocked by the limiter 14, preventing the connecting seat 20 from exceeding the preset movement path, reducing the risk of the connecting seat 20 colliding with other components of the test bench 10 or leaving the test area due to excessive movement, and improving the stability and safety of the test environment.

[0034] Furthermore, the clamping mechanism 40 in this embodiment can be a clamping block type clamping mechanism, such as being formed by two opposing clamping blocks. The inner surface of the clamping blocks is usually designed to fit the shape of the handle 2. The two clamping blocks can be elastically connected or relatively slidingly connected to move closer or further apart to clamp or release the handle 2. After clamping the handle 2, the connecting parts can be locked by screws or bolts to lock the clamping blocks and achieve stable clamping.

[0035] Of course, the clamping mechanism 40 can also consist of two opposing clamping blocks, a drive mechanism, and a guide. The drive mechanism can be a cylinder, hydraulic cylinder, or electric push rod, etc., providing power to drive the clamping blocks to move. The guide consists of a guide rail and a slider, allowing the clamping blocks to move along a predetermined direction to achieve clamping and releasing actions. When it is necessary to clamp the handle 2, the piston of the drive mechanism (such as a cylinder) extends, pushing one of the clamping blocks along the guide towards the handle 2 through the connecting component. At the same time, the other clamping block also moves towards the handle 2 synchronously under the action of the corresponding drive mechanism. The two clamping blocks gradually approach each other and tightly clamp the handle 2, achieving clamping.

[0036] In another embodiment, the clamping mechanism 40 can also be an existing clamping mechanism, such as two clamping arms connected by a pivot or hinge. External force (such as a manual lever, pneumatic or electric actuator) causes the clamping arms to rotate around the pivot, thereby opening and closing the clamping arms to grip the handle 2. There are various ways to configure the clamping mechanism 40; the specific configuration can be determined according to actual needs.

[0037] More specifically, in this embodiment, the driving component 50 can be a drive motor (such as a stepper motor or a servo motor), and the output shaft of the driving component 50 is directly connected to the clamping mechanism 40 through mechanical structures such as couplings and keyways, so as to directly drive the clamping mechanism 40 to rotate.

[0038] As a preferred embodiment, in this embodiment, a first slider 21 is provided at the bottom of the connecting seat 20, and a first slide rail 11 is provided on the test platform 10. The first slide rail 11 is extended along the first direction, and the first slider 21 slides in cooperation with the first slide rail 11. In this way, when it is necessary to drive the connecting seat 20 to move along the first direction, only a slight external force needs to be applied to the connecting seat 20 to drive the connecting seat 20 to reciprocate along the first direction, so as to move closer to or away from the adjusting seat 30.

[0039] Compared to other moving connection methods, this sliding connection structure is relatively simple, consisting of a slider and a rail, without complex transmission components or joint structures, reducing potential failure points and wear areas. Therefore, it boasts high reliability, maintains good performance over extended periods of use, and is suitable for various working environments.

[0040] More specifically, in this embodiment, there are two first slide rails 11 and two slide rails are provided at the bottom of the connecting seat 20. The two sliders slide in cooperation with the two slide rails, making the movement of the connecting seat 20 more stable.

[0041] It should be noted that, based on the first slide rail 11, limiting members 14 can be set at both ends of the first slide rail 11 to prevent the connecting seat 20 from exceeding the preset movement path.

[0042] Furthermore, the test bench 10 is provided with a second slide rail 12, which extends along a second direction perpendicular to the first direction. The bottom of the adjustment seat 30 is provided with a second slider 34, which slides in cooperation with the second slide rail 12 to drive the test component 3 to move along the second direction.

[0043] Based on this structure, taking the width direction of the test platform 10 as an example, the second direction is extended along the width direction (second direction) of the test platform 10. The adjustment seat 30 can slide in this direction, so that the clamping mechanism 40 provided on the adjustment seat 30 can be adjusted in a two-dimensional plane. When the handle 2 moves close to the adjustment seat 30 in the length direction (first direction) of the test platform 10, if the clamping mechanism 40 is aligned with the handle 2 in the first direction, but there is a deviation in the width direction, the position of the clamping mechanism 40 in the width direction can be adjusted by sliding the adjustment seat 30 in the second direction, so that it can be accurately aligned with the handle 2, so that the handle 2 can be reliably clamped.

[0044] In actual operation, since the position of handle 2 may be uncertain, by adjusting the first direction and the second direction respectively, the operator can flexibly control the movement of the adjusting seat 30 and the clamping mechanism 40 according to the actual position of handle 2, so as to adapt to handle 2 in different positions, thereby increasing the flexibility and convenience of operation.

[0045] Similarly, two second slide rails 12 and two second sliders 34 can be provided to ensure stable movement of the adjusting seat 30 in the second direction. Simultaneously, limiting members 14 (such as limiting posts or limiting blocks) are provided at both ends of the second slide rail 12. These limiting members 14 abut against the adjusting seat 30 when it reaches the end of its stroke in the second direction. Thus, when the adjusting seat 30 moves in the second direction and abuts against one of the limiting members 14, the adjusting seat 30 is blocked by the limiting member 14, preventing it from exceeding the preset movement path. This reduces the risk of the adjusting seat 30 colliding with other components of the test bench 10 or leaving the test area due to excessive movement, improving the stability and safety of the test environment.

[0046] Furthermore, the adjusting base 30 is provided with a mounting base 31 and an adjusting assembly 33. Specifically, the adjusting assembly 33 includes an adjusting rod 331, an adjusting nut 333, and an adjusting plate 332. One end of the adjusting plate 332 is connected to the adjusting nut 333, and the other end of the adjusting plate 332 is connected to the mounting base 31. The adjusting rod 331 extends along a third direction perpendicular to the first and second directions. The adjusting nut 333 is threadedly engaged with the adjusting rod 331. When the adjusting rod 331 rotates, the adjusting nut 333 moves along the third direction, causing the adjusting plate 332 to move along the third direction, thereby causing the mounting base 31 to move along the third direction.

[0047] Based on this structure, taking the height direction of the test platform 10 as an example, the adjusting rod 331 and the adjusting nut 333 are threaded together. When the adjusting rod 331 is rotated, the adjusting nut 333 will move linearly along the third direction, thereby driving the adjusting plate 332 to move linearly along the third direction. In this way, the mounting base 31 connected to the adjusting plate 332 and the clamping mechanism 40 located on the mounting base 31 can be finely adjusted in position in the third direction.

[0048] Thus, if the clamping mechanism 40 approaches the adjusting seat 30 along the first direction (the length direction of the test platform 10) and aligns with the handle 2 along the second direction (the width direction of the test platform 10), and there is still a deviation in the height direction (third direction) of the adjusting seat 30, simply rotate the adjusting rod 331 to move the adjusting plate 332 in the third direction to adjust the position of the clamping mechanism 40 in the third direction until the clamping mechanism 40 is aligned with the handle 2, so that the clamping mechanism 40 can be finely adjusted in three-dimensional space. Combining the adjustments of the clamping mechanism 40 in the first and second directions mentioned above, the clamping mechanism 40 can be aligned with the handle 2 in different positions and postures, adapting to various complex testing requirements and greatly improving the flexibility and applicability of the entire device.

[0049] Compared to some methods that require manually pushing or pulling the mounting base 31 to adjust the position, adjusting by rotating the adjusting rod 331 is more labor-saving and convenient, reducing the workload of operators and improving work efficiency.

[0050] It should be noted that the adjusting rod 331 in this embodiment can be an existing lead screw, and the adjusting nut 333 can be a lead screw nut that matches and is threaded together.

[0051] In addition, a handle 3311 is provided on the adjusting rod 331. The handle 3311 is located at the end of the adjusting rod 331 away from the test platform 10. The handle 3311 provides the operator with a convenient grip, making it easy to apply force to rotate the adjusting rod 331.

[0052] Furthermore, the adjusting seat 30 is provided with a mounting seat 31 and a third slide rail 32. The third slide rail 32 extends along a third direction. The bottom of the mounting seat 31 is provided with a third slider 311. The third slider 311 slides in cooperation with the third slide rail 32 to drive the mounting seat 31 to move along a third direction.

[0053] Specifically, when the mounting base 31 moves along a third direction under the drive of the adjusting plate 332, the third slider 311 slides in cooperation with the third slide rail 32, and the third slide rail 32 provides guidance for the third slider 311, making the mounting base 31 move more smoothly along the third direction and reducing jamming or shaking.

[0054] Compared to relying solely on the adjusting rod 331 to drive the mounting base 31, the cooperation between the third slider 311 and the third slide rail 32 can better guide the mounting base 31 to move in a straight line, improve the smoothness of the movement, and avoid the mounting base 31 from tilting or swaying due to the rotation of the adjusting rod 331. This improves the accuracy and stability of the clamping mechanism 40 in the third direction, which is beneficial for achieving the clamping operation of the target object.

[0055] Furthermore, the clamping mechanism 40 includes a first clamping block 41, a second clamping block 42, and a mounting plate 43. The first clamping block 41 and the second clamping block 42 are spaced apart on the mounting plate 43. When the first clamping block 41 and / or the second clamping block 42 are subjected to force, they move closer to each other or further apart, clamping the handle 2 when they move closer to each other or releasing the handle 2 when they move further apart. The driving member 50 is connected to the mounting plate 43 and drives the mounting plate 43 to rotate.

[0056] Based on this structure, during assembly, the first clamping block 41 and the second clamping block 42 are spaced apart. Specifically, the first clamping block 41 and the second clamping block 42 can be connected by elastic components (such as springs or elastic blocks). When it is necessary to clamp the handle 2, the operator can apply external force to the first clamping block 41 or the second clamping block 42, or apply external force to the first clamping block 41 and the second clamping block 42 with both hands at the same time, so that the elastic component between the first clamping block 41 and the second clamping block 42 is stretched, so that the first clamping block 41 and the second clamping block 42 move away from each other to form a gap larger than the size of the handle 2. At this time, the handle 2 is placed in the gap between the first clamping block 41 and the second clamping block 42. Then, the operator stops applying external force. At this time, the elastic component returns to its own deformation, so that the first clamping block 41 and the second clamping block 42 move closer to each other, thereby generating a clamping force on the handle 2 and achieving clamping of the handle 2. Subsequently, the mounting plate 43 is rotated by the drive component 50, which in turn drives the clamping mechanism 40 to rotate, and the handle 2 is tested.

[0057] After the handle 2 has been tested, simply apply external force to the first clamping block 41 or the second clamping block 42 again to stretch the elastic component between the first clamping block 41 and the second clamping block 42, so that the two clamping blocks move away from each other to form a gap larger than the size of the handle 2. At this time, the handle 2 can be removed, and then the clamping mechanism 40 returns to its initial state.

[0058] Of course, during installation, a bidirectional threaded rod can also be installed on the mounting plate 43. The two ends of the threaded rod have threads with opposite directions of rotation. Simultaneously, the first clamping block 41 and the second clamping block 42 each have threaded holes that match the threads at both ends of the threaded rod. The two clamping blocks are then installed on the threaded rod through these threaded holes. When the threaded rod is rotated, because the threads at both ends rotate in opposite directions, the two clamping blocks will move in opposite directions along the axial direction of the threaded rod, thus moving closer or further apart, thereby clamping or releasing the handle 2.

[0059] In this way, by using clamping blocks that are spaced apart and can move closer or further apart when subjected to force, the clamping interval can be flexibly adjusted according to the thickness and other dimensions of the handle 2, thereby adapting to the clamping requirements of various different specifications of handle 2 and improving the versatility and applicability of the clamping mechanism 40.

[0060] Furthermore, the clamping mechanism 40 also includes a locking rod 44 and a locking member 441. One end of the locking rod 44 is fixed to the second clamping block 42, and the other end of the locking rod 44 passes through the first clamping block 41. The locking member 441 is installed on the first clamping block 41 and connected to the locking rod 44 to lock or release the first clamping block 41.

[0061] Based on this structure, during assembly, the locking element 441 can be rotatably sleeved on the locking rod 44. When it is necessary to clamp the handle 2, the locking element 441 can be rotated to move away from the second clamping block 42. At this time, the first clamping block 41 can move away from the second clamping block 42 along the axial direction (i.e., the length direction) of the locking rod 44, so that a gap is formed between the first clamping block 41 and the fixed second clamping block 42. At this time, the handle 2 can be placed between the first clamping block 41 and the second clamping block 42 for clamping. Within the interval, the locking member 441 is then rotated. Since the locking member 441 is rotatably connected to one end of the locking rod 44, during the rotation, the locking member 441 will gradually press against the first clamping block 41. As the locking member 441 continues to rotate, the first clamping block 41 that is pressed against will move along the locking rod 44 towards the second clamping block 42, thereby getting closer to the second clamping block 42 until it can make close contact with the handle 2 and generate sufficient clamping force. At this time, the rotation of the locking member 441 is stopped, and the handle 2 is firmly clamped.

[0062] Similarly, when it is necessary to release the handle 2, simply rotate the locking member 441 in the opposite direction so that the locking member 441 gradually moves away from the first clamping block 41 that is being pressed. As the locking member 441 rotates, the pressure on the first clamping block 41 gradually decreases. Without the action of external force, the first clamping block 41 and the second clamping block 42 return to their original interval state, and the handle 2 can be taken out.

[0063] It should be noted that in this embodiment, the locking rod 44 can be a screw, and the locking element 441 can be an existing nut that is threaded to the screw. One end of the locking rod 44 is fixedly connected to the second clamping block 42, so that the second clamping block 42 remains fixed. The threaded end of the locking rod 44 passes through the first clamping block 41. Thus, when it is necessary to clamp the handle 2, the nut is rotated. Due to the action of the thread, the nut will move axially along the locking rod 44, thereby pressing against the first clamping block 41, causing the first clamping block 41 to move closer to the second clamping block 42 to clamp the handle 2. When the handle 2 is released, the nut is rotated in the opposite direction, and the nut moves in the opposite direction, releasing the pressure on the first clamping block 41, thereby unlocking the handle 2.

[0064] Furthermore, the clamping mechanism 40 also includes at least two guide rods 45, one end of each guide rod 45 is fixed to the second clamping block 42, and the other end of each guide rod 45 passes through the first clamping block 41. The first clamping block 41 can move along the guide rods 45 in a third direction (i.e., the height direction of the test platform 10).

[0065] In a specific configuration, the guide rod 45 can be extended along a third direction (i.e., the height direction of the test platform 10). In this way, when the first clamping block 41 moves closer to or further away from the second clamping block 42 in the third direction, it can only move along the extension direction of the guide rod 45 (i.e., the height direction of the test platform 10). The guide rod 45 plays a guiding role, preventing the first clamping block 41 from shifting, shaking, or twisting when subjected to external force or during clamping. This allows the first clamping blocks 41 to move closer to or further away from each other in a predetermined direction, thus achieving stable clamping of the handle 2.

[0066] It should be noted that the guide rods 45 are set to two, three or more, depending on the size of the first clamping block 41, in order to meet the actual guiding requirements and enable the first clamping block 41 to move stably in the third direction.

[0067] Furthermore, the test bench 10 is equipped with two locking components 13, which are respectively connected to the connecting seat 20 and the adjusting seat 30. Specifically, the locking component 13 includes a latch 131 and a locking rod 132. One end of the latch 131 is connected to the connecting seat 20 or the adjusting seat 30, and the other end of the latch 131 is rotatably connected to the locking rod 132. When the latch 131 rotates, it drives the locking rod 132 to move up and down along its own axis to lock or unlock the connecting seat 20 or the adjusting seat 30.

[0068] Specifically, during assembly, one end of the latch 131 of one of the locking components 13 is connected to the connecting seat 20, and the other end of the latch 131 is rotatably connected to the locking rod 132. When it is necessary to lock the connecting seat 20, an external force is applied to the latch 131 connected to the connecting seat 20 towards the test platform 10, causing the latch 131 to rotate downwards along its own axial direction (i.e., the vertical direction of the test platform 10, i.e., the height direction) towards the end face of the test platform 10. This causes the locking rod 132 to move downwards along the vertical direction of the test platform 10 until it abuts against the test platform 10. At this time, friction and pressure are generated between the locking rod 132 and the test platform 10, and these friction and pressure prevent the connecting seat 20 from moving horizontally. Meanwhile, because the latch 131 is connected to the connecting seat 20, the locking lever 132 generates an upward supporting force on the connecting seat 20 through the latch 131, which restricts the movement of the connecting seat 20 in the vertical direction. Under the constraints in the horizontal and vertical directions, the connecting seat 20 is firmly fixed in the current position, thereby achieving the locking of the connecting seat 20, so as to avoid the connecting seat 20 from shaking due to external force during the testing of the device under test 1, and reduce the probability of the device under test 1 shaking during the testing of the handle 2.

[0069] When it is necessary to release the connecting seat 20, the locking buckle 131 is rotated in the opposite direction, causing the locking rod 132 to move upward along the vertical direction of the test platform 10. This causes the locking rod 132 to gradually move away from the test platform 10. As the locking rod 132 moves upward, the friction and pressure between it and the test platform 10 gradually decrease until they disappear, releasing the horizontal constraint on the connecting seat 20. Simultaneously, the upward support force exerted by the locking rod 132 on the connecting seat 20 through the locking buckle 131 also disappears, releasing the vertical constraint on the connecting seat 20. At this point, the connecting seat 20 is no longer restricted by the locking rod 132 and can move freely on the test platform 10 or undergo other operations, thus achieving the release of the connecting seat 20.

[0070] Similarly, one end of the latch 131 of another locking member 13 is connected to the adjusting seat 30, and the other end is rotatably connected to the locking rod 132 of the locking member 13. When it is necessary to lock the adjusting seat 30, similar to the locking connection method, simply rotate it downwards or upwards along the vertical direction of the test platform 10 to move the locking rod 132 up and down along the vertical direction of the test platform 10, thereby locking or unlocking the adjusting seat 30. This prevents the adjusting seat 30 from shaking due to external forces during the testing process of the clamping mechanism 40, reducing the probability of the clamping mechanism 40 shaking during testing.

[0071] It should be noted that during assembly, a connecting piece can be externally installed on the connecting seat 20 and the adjusting seat 30, and the latch 131 can be rotatably connected to the connecting piece via a rotating shaft. By setting some structures to increase friction at the rotating shaft, such as using rubber washers, damping oil, or special coatings, the coefficient of friction between the rotating shaft and the latch 131 can be increased. This allows the latch 131 to resist the reverse tendency caused by vibration or other external forces when it rotates downwards, so that the two locking rods 132 can stably lock the connecting seat 20 and the adjusting seat 30.
