Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of instrument inspection, and in particular to an auxiliary clamping device and a detection device. Background Art
[0002] As the frequency and accuracy requirements for hardware signal testing continue to increase, the use of passive probes with precise measurement capabilities has increased significantly. To achieve high test accuracy, traditional passive single-ended probes typically require a short ground ring for grounding. However, the small size and stiffness of a short ground ring make it difficult to operate, limiting the user's ability to capture only one signal at a time. Furthermore, due to the limited size of the operator's hand, it is not suitable for testing test points in small spaces. Utility Model Content
[0003] The main purpose of the utility model is to provide an auxiliary clamping device and a detection device, aiming to improve the convenience of operating a passive probe and expand the scope of use of the passive probe.
[0004] The utility model provides an auxiliary clamping device, which is used to fix a passive probe. The passive probe includes a body and a ground pin electrically connected to the body. The auxiliary clamping device includes:
[0005] a first arm, wherein a first fixing portion is provided on the first arm for fixing the body;
[0006] a second arm, wherein a second fixing portion is provided on the second arm for fixing the earth pin;
[0007] The first arm and the second arm are connected via a support member, and the support member is provided with an adjustment portion for adjusting the relative position between the first arm and the second arm.
[0008] The present application also provides a detection device, comprising:
[0009] Auxiliary clamping device as described above;
[0010] the body fixed on the first fixing portion;
[0011] The ground pin is fixed on the second fixing portion.
[0012] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:
[0013] The utility model discloses an auxiliary clamping device and a detection device for fixing a passive probe, wherein the passive probe includes a body and a ground pin electrically connected to the body, and the auxiliary clamping device includes a first arm, a second arm, and an adjustable support member connecting the first arm and the second arm. The operator controls the probe and the ground pin by controlling the two arms with only one hand, and adjusts the distance and angle between the probe and the ground pin to perform single-ended signal testing, thereby improving the convenience of using the passive probe. Moreover, since the auxiliary clamping device is much smaller than a person's fingers, it gets rid of the pain point that traditional passive probes require two hands to test only one set of signals and cannot penetrate into the test position with a small space, thereby greatly improving the test efficiency, saving labor costs, improving the test accuracy and reliability, and expanding the scope of use of the passive probe. In addition, by operating the adjustment part of the support member, the operator can adjust the relative position between the first arm and the second arm according to the test requirements, thereby realizing the simultaneous testing of single-ended signals in different planes or directions. The embodiment of the present application can be applied to various complex test environments for multi-angle detection of passive probes of different sizes, and has a high degree of flexibility and adaptability.

[0029] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0031] like Figure 1 、 Figure 5 As shown, an embodiment of the present application provides an auxiliary clamping device for installing a passive probe. The passive probe includes a main body 1 and a ground pin 2 electrically connected to the main body 1. The auxiliary clamping device includes a first arm 10 and a second arm 20. The first arm 10 is provided with a first fixing portion 11 for fixing the main body 1. The second arm 20 is provided with a second fixing portion 21 for fixing the ground pin 2. The first arm 10 and the second arm 20 are connected by a support member 30. The support member 30 is provided with an adjustment portion 31 for adjusting the relative position between the first arm 10 and the second arm 20.
[0032] It should be understood that the passive probe includes a main body 1 and a ground pin 2 connected to the main body 1 through a short ground wire. Traditional passive single-ended probes usually need to be grounded through a short ground ring. The short ground ring is small in size and relatively hard, which makes the operator's operation feel not ideal, and a single person can only capture one group of signals at a time. And due to the size of the operator's hand, it cannot test test points in a smaller space. Based on this, in various testing scenarios, it is often necessary to fix and position the passive probe to ensure the accuracy of the test. However, traditional fixing fixtures are often of a single design and are difficult to adapt to the detection needs of measured signals in different planes and directions.
[0033] In order to improve the above situation, the present application provides an auxiliary clamping device, including a first arm 10 and a second arm 20, to clamp or fix the probe body 1 and the ground needle 2. The first arm 10 and the second arm 20 can be in the shape of long strips and respectively provided with a free end and a fixed end along their own length direction. The two free ends can carry the probe body 1 and the ground needle 2 and extend into the test space to capture the test signal. The two fixed ends are connected by a support member 30. The support member is provided with an adjusting portion 31 for adjusting the telescopic length of the support member 30, thereby adjusting the distance between the first arm 10 and the second arm 20, and thereby changing the distance between the two free ends. In addition, the adjusting portion 31 can also be used to adjust the rotation direction of the support member 30, thereby adjusting the angle between the first arm 10 and the second arm 20, and thereby changing the angle between the two free ends.
[0034] It should be explained that, during use, only the telescopic length of the support member 30 can be adjusted to adjust the distance between the first arm 10 and the second arm 20. Alternatively, only the rotation direction of the support member 30 can be adjusted to adjust the angle between the first arm and the second arm. The telescopic length and rotation direction of the support member 30 can also be adjusted simultaneously to simultaneously adjust the distance and angle between the first arm and the second arm. In other words, the telescopic length or rotation direction of the support member 30 can be adjusted independently or synchronously to achieve simultaneous testing of single-ended signals in different planes or directions, so as to be flexibly applicable to various complex test environments for multi-angle detection of passive probes.
[0035] As an embodiment, the adjustment portion 31 includes a first sliding body 321 and a slide rail 322. The first sliding body 321 slides on the slide rail 322 in a direction parallel to the axis of the support member 30 to adjust the distance between the first arm 10 and the second arm 20. Furthermore, the first sliding body 321 can also slide in a direction perpendicular to the axis of the support member 30 to adjust the angle between the first arm 10 and the second arm 20. In some examples, a bolt and nut combination can also be used to achieve relative movement to adjust the distance. In short, by sliding the first sliding body 321 in both directions on the slide rail 322, it is possible to control both the distance between the first arm 10 and the second arm 20 and the angle between the two. The embodiment of the present application can adapt the passive probe to various test environments through a simple structure, further increasing the flexibility of operation.
[0036] As an embodiment, the adjustment part 31 includes a first rotating shaft provided on the first arm 10 or the second arm 20, and a first rotating arm installed on the first rotating shaft. When the first rotating shaft is provided on the first arm 10, the end of the first rotating arm away from the first rotating shaft is integrally connected to the second arm 20. Similarly, when the first rotating shaft is provided on the second arm 20, the end of the first rotating arm away from the first rotating shaft is integrally connected to the first arm 10. By rotating the first rotating arm around the first rotating shaft, the distance between the first arm 10 and the second arm 20 is adjusted, and the angle between the first arm 10 and the second arm 20 is adjusted. The setting of this adjustment structure enables the operator to adjust the positional relationship between the first arm 10 and the second arm 20 in two different planes. The two different planes can be in a parallel relationship, a perpendicular relationship, or a cross relationship. Therefore, the embodiment of the present application provides a higher degree of adjustment freedom and better environmental adaptability, which is convenient for multi-angle fixation and multi-dimensional detection of the passive probe.
[0037] Of course, the above method is only exemplary. In other embodiments, the distance and angle between the first arm 10 and the second arm 20 can be adjusted by other methods, which are not limited here.
[0038] Optionally, the adjustment portion 31 further includes a locking device 33 for fixing the position of the first sliding body 321 (such as a slider, a slide, a sleeve, etc.) after the distance or angle between the first arm 10 and the second arm 20 is adjusted to a preset distance and / or a predetermined angle, thereby ensuring stability during the test.
[0039] In some optional embodiments, referring to Figure 1The auxiliary clamping device also includes a gripping portion 40. The gripping portion 40 is detachably connected to the support member 30 and is mounted on a side of the support member 30 away from the first arm 10 and the second arm 20. During use, the operator does not need to directly grip the first arm 10 and the second arm 20, thereby avoiding hand fatigue or reduced adjustment accuracy caused by prolonged operation or fine adjustment. Operation through the gripping portion 40 reduces direct contact with the support arms and the burden of operation. This is ergonomic, improves the convenience and comfort of operation, and is also suitable for various test environments requiring more precise positioning, further improving test accuracy.
[0040] In one embodiment, a second threaded rod 34 is provided on the side of the support member 30 facing away from the first arm 10 and the second arm 20. The grip portion 40 is provided with a threaded hole 41. The second threaded rod 34 is screwed into the threaded hole 41 to facilitate the fixation and removal of the grip portion 40. In some examples, welding, riveting, snap-fit connection, pin connection, etc. can also be used to achieve the fixed connection between the grip portion 40 and the support member 30. Among them, the screw-on connection method is both simple to operate and provides a stable connection. It does not require the shape of the connecting components to be changed, and the simple structure allows for quick disassembly, thereby improving ease of use.
[0041] In one embodiment, a second rotation axis 35 is provided on the side of the support member 30 facing away from the first arm 10 and the second arm 20. The grip portion 40 is detachably mounted on the second rotation axis 35 and rotates about the second rotation axis 35 to adjust the orientation of the free ends of the first arm 10 and the second arm 20, adapting to testing requirements in different directions and expanding the range of use of the passive probe.
[0042] In some optional embodiments, reference Figure 1 To increase the adjustable length range of the grip 40 and thereby capture a wider range of signals to be tested, the grip 40 itself can be configured to have an adjustable length. Optionally, the grip 40 can include at least two sleeved tubes. One tube can extend or retract from the other, or one tube can be threadedly connected to the other, allowing the grip 40 to be extended or retracted by rotating one of the tubes.
[0043] In one embodiment, the grip portion 40 includes a first rod 421 and a first sleeve 422 having an inner diameter larger than that of the first rod 421. The first rod 421 is provided with a bolt having external threads. The first sleeve 422 is internally provided with mating internal threads. The first rod 421 is rotated and inserted into the first sleeve 422 to adjust the length of the grip portion 40. In the first embodiment, one end of the first rod 421 is detachably connected to the support member 30, and the other end of the first rod 421 is rotated and inserted into the first sleeve 422. In another embodiment, one end of the first sleeve 422 is detachably connected to the support member 30, and the other end of the first sleeve 422 is inserted into the first rod 421. The positions of the first rod 421 and the first sleeve 422 can be interchanged. Of course, the above method is merely exemplary. In other embodiments, the length of the grip portion 40 can be adjusted using other methods to accommodate test spaces of varying depths and improve the accuracy and versatility of testing. This is not intended to be limiting.
[0044] In some optional embodiments, reference Figure 1 In order to increase the adjustable length range of the first arm 10 and the second arm 20 so that the test signal can be captured in a larger range, the first arm 10 and the second arm 20 themselves can be set to a structure with adjustable length.
[0045] In one embodiment, the first arm 10 includes a second sliding body 121 and a second sleeve 122. The second sliding body 121 is inserted into the second sleeve 122 along the axis of the first arm 10 and slides to adjust the length of the first arm 10. The inner diameter of the second sleeve 122 is designed to match the outer diameter of the second sliding body 121 to ensure that the second sliding body 121 can slide freely within it. Furthermore, the second sleeve 122 includes a guide rail to guide the movement of the second sliding body 121 within the second sleeve 122, ensuring that it slides along a straight line or a specific path. During use, the second sliding body 121 can be moved manually or automatically along the guide rail within the second sleeve 122 to a preset position to accommodate test chambers of varying depths. Optionally, the first arm 10 may be provided with a locking device to secure the position of the second sliding body 121 after adjustment to the preset position, preventing it from sliding during operation and ensuring stability during testing. Common locking devices include screws, clamps, and locking pins.
[0046] In some examples, the first arm 10 includes a telescopic rod. The telescopic rod is composed of multiple nested tubular components, and the length of the first arm 10 is adjusted by rotating or pushing the outer tube to adjust the extension length of the inner tube. In other examples, the first arm includes a hinge and connecting rod structure. The first arm 10 is connected by a hinge, and the length of the first arm 10 is adjusted by adjusting the length of the connecting rod. Optionally, the first arm 10 can also be configured as other retractable structures, such as a foldable or segmented structure, and the length of the first arm 10 can be adjusted by unfolding or connecting the segments. For example, it can be configured as a spring-connected structure, and the length of the first arm 10 can be adjusted by a telescopic spring.
[0047] Of course, the above method is only exemplary. In other embodiments, the length of the first arm 10 can be adjusted by other methods, which are not limited here.
[0048] In one embodiment, the second arm 20 includes a third slider 221 and a third sleeve 222. The third slider 221 is inserted into the third sleeve 222 along the axis of the second arm 20 and slides to adjust the length of the second arm 20. The inner diameter of the third sleeve 222 is designed to match the outer diameter of the third slider 221 to ensure that the third slider 221 can slide freely within it. Furthermore, the third sleeve 222 includes a guide rail to guide the movement of the third slider 221 within the third sleeve, ensuring that it slides along a straight line or a specific path. During use, the third slider 221 can be moved manually or automatically along the guide rail within the third sleeve 222 to a preset position to accommodate test chambers of varying depths. Optionally, the second arm 20 may be provided with a locking device to secure the third slider 221 in place after adjustment to the preset position, preventing it from sliding during operation and ensuring stability during testing. Common locking devices include screws, clamps, and locking pins.
[0049] In some examples, the second arm 20 includes a telescopic rod. The telescopic rod is composed of multiple nested tubular components, and the length of the first arm 20 is adjusted by rotating or pushing the outer tube to adjust the extension length of the inner tube. In other examples, the first arm includes a hinge and connecting rod structure. The second arm 20 is connected by a hinge, and the length of the second arm 20 is adjusted by adjusting the length of the connecting rod. Optionally, the second arm 20 can also be configured as other retractable structures, such as a foldable or segmented structure, and the length of the second arm 20 can be adjusted by unfolding or connecting the segments. For example, it can be configured as a spring-connected structure, and the length of the second arm 10 can be adjusted by a telescopic spring.
[0050] Of course, the above method is only exemplary. In other embodiments, the length of the second arm 20 can be adjusted by other methods, which are not limited here.
[0051] In some optional embodiments, reference Figure 1 In order to increase the adjustable width range of the first arm 10 and the second arm 20 so as to capture the test signal in a larger range, the first arm 20 and the second arm 20 themselves can be set as a structure with adjustable width.
[0052] In one embodiment, the first arm 10 includes a fourth slider 131 and a first inline housing 132. The fourth slider 131 is embedded in the first inline housing 132 perpendicular to the axis of the first arm 10 and slides to adjust the width of the first arm 10. As part of the support arm, the first inline housing 132 has an internal cavity or channel to accommodate the fourth slider 131. The inner wall design of the first inline housing 132 matches the outer wall design of the fourth slider 131, ensuring that the fourth slider 131 can slide freely perpendicular to the axis of the first arm 10 to accommodate test spaces of varying narrowness. Furthermore, the first inline housing 132 includes a guide rail to guide the fourth slider 131, ensuring that it slides along a straight line or a specific path. During use, the fourth slider 131 can be moved manually or automatically along the guide rail within the first inline housing 132 to a preset position. Optionally, a locking device may be provided on the first arm 10 to fix the position of the fourth sliding body 131 after adjusting to a preset position, thereby preventing it from sliding during operation and ensuring stability during testing. Common locking devices include screws, clamping devices, locking pins, etc.
[0053] In some examples, the first arm 10 can be configured as another retractable structure, such as a foldable or segmented structure, where the width of the first arm 10 can be adjusted by unfolding or connecting the segments. For another example, the first arm 10 can be configured as a spring-connected structure, where the width of the first arm 10 can be adjusted by extending or retracting the spring.
[0054] Of course, the above method is only exemplary. In other embodiments, the width of the first arm 10 can be adjusted by other methods, which are not limited here.
[0055] In one embodiment, the second arm 20 includes a fifth slider 231 and a second inline housing 232. The fifth slider 231 is embedded in the second inline housing 232 perpendicular to the axis of the second arm 20 and slides to adjust the width of the second arm 20. As part of the support arm, the second inline housing 232 has an internal cavity or channel to accommodate the fifth slider 231. The inner wall design of the second inline housing 232 matches the outer wall design of the fifth slider 231, ensuring that the fifth slider 231 can slide freely perpendicular to the axis of the second arm 20 to accommodate test spaces of varying degrees of narrowness. Furthermore, the second inline housing 232 includes a guide rail to guide the fifth slider 231, ensuring that it slides along a straight line or a specific path. During use, the fifth slider 231 can be moved manually or automatically along the guide rail within the second inline housing 232 to a predetermined position. Optionally, a locking device may be provided on the second arm 20 to fix the position of the fifth sliding body 231 after adjusting to a preset position, thereby preventing it from sliding during operation and ensuring stability during testing. Common locking devices include screws, clamping devices, locking pins, etc.
[0056] In some examples, the second arm 20 can be configured as another retractable structure, such as a foldable or segmented structure, where the width of the second arm 20 can be adjusted by unfolding or connecting the segments. For another example, the second arm 20 can be configured as a spring-connected structure, where the width of the second arm 20 can be adjusted by extending or retracting the spring.
[0057] Of course, the above method is only exemplary. In other embodiments, the width of the second arm 20 can be adjusted by other methods, which are not limited here.
[0058] In some optional embodiments, combined with Figure 1 、 Figure 4 To increase the adjustable width range of the second arm 20 and thereby capture test signals over a wider range, at least one spare part, namely a third arm 70, can be prepared. The width of the third arm 70 is different from that of the second arm 20. Based on test requirements, the operator can remove the second arm from the third sleeve 222 and securely install the third arm 70 in the third sleeve 222 to accommodate test spaces of varying degrees of narrowness.
[0059] Reference Figure 1 、 Figure 2 A first fixing portion 11 is provided on the first arm 10 for fixing the passive probe body 1 .
[0060] As an embodiment, the first fixing portion 11 includes an open ring 14 and a first fastening device 15. The open ring 14 is used to fix the body 1. The first fastening device 15 is used to fasten the open ring 14 to the first arm 10.
[0061] In some examples, the first fixing portion 10 can also be set to other structures to fix the passive probe body 1. For example, the first fixing portion 11 can be set to a slot fitting structure. The body 1 can be inserted into the slot and fixed to achieve quick loading and unloading and precise positioning. Or the first fixing portion 11 can be set to a magnetic adsorption structure. The body 1 is adsorbed to the first arm 10 through magnetic material to achieve quick fixation and release. Or the first fixing portion 11 is set to an adhesive fixing structure. By using an adhesive or adhesive material, the body 1 is fixed to a preset position of the first arm 10 to ensure its stability. In other examples, the first fixing portion 11 adopts an elastic clamping structure. The elastic deformation of the elastic material is used to adapt to probes of different sizes and to achieve stable fixation of the probe. In other embodiments, the fixation of the body 1 can also be achieved by other means, which are not limited here.
[0062] As a preferred embodiment, refer to Figure 2 The first fastening device 15 includes a first connecting piece 1511 extending from the open ring 14, a third nut hole 1512 in the first connecting piece 1511, and a second connecting piece 1521 extending from the first arm 10, and a fourth nut hole 1522 in the second connecting piece 1521. The third nut hole 1512 and the fourth nut hole 1522 are connected by means of a first stud 1523. When in use, the operator loosens the first stud 1523. On the one hand, the diameter of the open ring 14 can be adjusted to adapt to passive probes of different sizes. On the other hand, the first fixing part 11 and the first arm 10 can rotate relative to each other. Rotating the first fixing part 11 adjusts the direction of the probe to meet the testing requirements of various complex spaces for multi-angle detection. After the adjustment is completed, tighten the first stud 1523 to fasten the open ring 14 to the first arm 10 to ensure stable clamping and precise guidance of the passive probe and improve the detection effect. In the embodiment of the present application, the setting of the open ring 14, compared with the slot matching structure, magnetic adsorption structure and adhesive fixing structure, can not only achieve stable fixation and convenient installation of the main body 1, but also achieve the effect of flexible control of the clamping size, and can make the main body 1 rotate flexibly with the rotation of the open ring 14 itself, thereby adapting to multi-angle detection needs, and the application scenarios are more extensive.
[0063] Optionally, the first connecting piece 1511 and the second connecting piece 1512 in the first fastening device 15 are connected by means of a spring. During use, the operator compresses the spring, which can adjust the diameter of the open ring 14 to accommodate passive probes of different sizes. On the other hand, the first fixing part 11 and the first arm 10 can also rotate relative to each other. The orientation of the probe is adjusted by rotating the first fixing part 11 to accommodate the testing requirements of various complex spaces for multi-angle detection. In other embodiments, the size and rotation direction of the first fixing part 11 can also be adjusted by other means, which are not limited here. In actual applications, due to the limitation of the elastic range of the spring, the compression range of the first connecting piece 1511 and the second connecting piece 1512 may be subject to certain restrictions. That is, the diameter adjustment range of the open ring 14 is affected by the elastic range. Therefore, compared with the spring fastening method, the operator adjusts the diameter of the open ring 14 by rotating the first stud 1523, and the fastening effect is better.
[0064] In some optional embodiments, referring to Figure 2 The first arm 10 is provided with a sixth sliding body 161 and a sliding groove 162 along the axis of the first arm 10. The first fastening device 15 is mounted on the sixth sliding body 161 to connect the first fixing portion 11 to the first arm 10. The sixth sliding body 161 slides along the sliding groove 162, causing the open ring 14 to move along the axis of the first arm 10. This facilitates rapid adjustment of the detection position, flexibly adjusts the distance between the probe on the body 1 and the ground pin 2, and improves the applicability of the auxiliary clamping device.
[0065] Reference Figure 1 、 Figure 3 A second fixing portion 21 is provided on the second arm for fixing the ground pin 2.
[0066] As an implementation method, refer to Figure 1 、 Figure 3 The second fixing portion 21 includes a mounting slot 24 and a slot width adjustment device 25. The slot width of the mounting slot 24 matches the diameter of the ground pin 2. The slot width adjustment device 25 is used to adjust the slot width of the mounting slot 24 to accommodate ground pins 2 of different sizes, thereby improving the applicability of the auxiliary clamping device.
[0067] In one embodiment, the second fixing portion 21 includes a third rotating shaft 261 mounted at one end of the second arm 20, and a fixing head 262 mounted on the third rotating shaft 261. The fixing head 262 rotates about the third rotating shaft 261 to adjust the orientation of the second fixing portion 21, and thereby the orientation of the earth pin 2, to accommodate detection requirements at different angles. The mounting slot 24 and the slot width adjustment device 25 are located on the fixing head 262.
[0068] As an embodiment, the slot width adjustment device 25 includes: a first hole 2511 and a second hole 2512 respectively located on the first side surface and the second side surface opposite to the fixing head 262, the first side surface and the second side surface being adjacent to the surface where the mounting slot 24 is located; a first connecting rod 2513 passing through the first hole 2511 and the second hole 2512, and the two ends of the first connecting rod 2513 are respectively provided with a first threaded portion and a second threaded portion; and further includes a first rotary vane 2521 and a second rotary vane 2522, the first rotary vane 2521 being provided at the first side surface, the first rotary vane 2521 having a fifth nut hole, the fifth nut hole being screwed into the first threaded portion, the second rotary vane 2522 being provided at the second side surface, the second rotary vane 2522 having a sixth nut hole, the sixth nut being screwed into the second threaded portion, and the slot width of the mounting slot 24 is adjusted by the first rotary vane 2521 and the second rotary vane 2522 to adapt to ground pins 2 of different sizes.
[0069] Optionally, the slot width adjustment device 25 includes: a first pressing plate, which is a first pressing element for clamping an object; a second pressing plate, which is a second pressing element for clamping an object, and is arranged opposite to the first pressing plate; a spring, which is arranged between the first pressing plate and the second pressing plate, and is used to provide a restoring force so that the two pressing plates can adapt to ground pins 2 of different diameters and maintain the clamping force. During use, the operator can adjust the distance between the two pressing plates according to the diameter of the clamped ground pin 2, and the spring compression automatically adjusts to adapt to the size of the ground pin 2 to achieve stable clamping. However, due to the limitation of the elastic range of the spring, the compression range of the first pressing plate and the second pressing plate may be affected to a certain extent. Therefore, compared with the spring compression method, the operator adjusts the slot width of the mounting slot 24 by rotating the first rotary plate 2521 and the second rotary plate 2522 to adapt to ground pins 2 of different sizes, and the adjustment effect is better.
[0070] In some examples, the second fixing portion can also be set to other structures, such as the second fixing portion 21 includes a mounting hole for fixing the ground pin 2. The mounting hole is provided at the free end of the second arm 20, and the inner wall of the mounting hole is made of elastic material. When in use, the ground pin 2 passes through the mounting hole, and the elastic material can make the mounting hole adapt to ground pins 2 of different sizes and realize the compression and fixation of the ground pin 2. It should be noted that the mounting hole can be directly provided on the second arm 20, or it can be provided on the fixing head 262 at the free end of the second arm 20. There is no restriction on the penetration direction of the mounting hole. However, due to the elastic range of the elastic material, the compression range of the mounting hole on the ground pin 2 is limited to a certain extent. Therefore, compared with the elastic fixation method of the mounting hole, the operator can more flexibly adjust the fixing size of the second fixing portion 21 through the mounting slot 24 and the slot width adjustment device 25, thereby more stably fixing the ground pin 2.
[0071] In some optional embodiments, reference Figure 4The auxiliary clamping tool also includes a first threaded rod 50. A first nut hole 511 matching the first threaded rod 50 is provided on the first arm 10. A second nut hole 512 matching the first threaded rod 50 is provided on the second arm 20. The first threaded rod 50 passes through the first nut hole 511 and the second nut hole 512 to fix the relative positions of the first arm 10 and the second arm 20. A first adjusting member 521 is provided on one side of the first threaded rod 50 passing through the first nut hole 511 on the first arm 10, and a second adjusting member 522 is provided on one side of the first threaded rod 50 passing through the second nut hole 512 on the second arm 20. The first adjusting member 521 and the second adjusting member 522 are used to adjust the telescopic length of the first threaded rod 50, thereby fixing the relative positions of the first arm 10 and the second arm 20. During use, loosen the first adjusting member 521 and / or the second adjusting member 522, and adjust the first sliding body 321 on the support member 30 until the distance between the first arm 10 and the second arm 20 is adjusted to a preset distance. To prevent the first arm 10 and the second arm 20 from sliding, tighten the first adjusting member 521 and the second adjusting member 522, so that the distance between the first arm 10 and the second arm 20 remains unchanged, thereby improving the stability of the test.
[0072] In some optional embodiments, reference Figure 6 The auxiliary clamping tool also includes an elastic member 60. The elastic member 60 is installed between the first support point of the first arm 10 and the second support point of the second arm 20 to fix the relative position of the first arm 10 and the second arm 20. The elastic member 60 can be made of an elastic material such as a spring or elastic resin. The first and second support points can be provided with positioning portions for mounting the elastic member. The ends of the elastic member are respectively sleeved on the two positioning portions and connected to the first and second arms 10 and 20, respectively, to prevent the elastic member from falling off the first and second arms 10 and 20. During use, the operator can adjust the first sliding body 321 on the support member 30 as needed until the distance between the first and second arms 10 and 20 is adjusted to a preset distance. The elastic member 60 will be compressed or stretched as the first sliding body 321 slides. When the first sliding body 321 slides to the preset position, the first adjusting member 521 and the second adjusting member 522 are tightened, the distance between the first and second arms 10 and 20 is maintained, the relative position between the probe and the ground pin 2 is determined, and the passive probe probe can perform instrument detection. When the test is completed, the first adjusting member 521 and / or the second adjusting member 522 is loosened, and the elastic member 60 returns to its original position, restoring the distance between the first arm 10 and the second arm 20 .
[0073] The provision of the first threaded rod 50 or the elastic member 60 enables the operator to adjust the distance between the first fixing portion 11 and the second fixing portion 21 more accurately and conveniently, thereby improving the accuracy of the distance between the probe and the ground pin 2, and further improving the accuracy of the passive probe test.
