Description

Technical Field

[0001] This application belongs to the field of temperature measurement technology, and specifically relates to a temperature measurement device for use in confined spaces. Background Technology

[0002] In industrial production, equipment maintenance, scientific research experiments, and other scenarios, temperature measurement is a key link in ensuring production efficiency, equipment safety, and the reliability of experimental data. Its measurement accuracy and ease of operation directly affect the overall work results.

[0003] In real-world industrial settings, temperature monitoring of many critical components must be performed within confined spaces, with electrolytic cells in the electrolysis industry serving as a prime example. Specifically, small windows are located at the top and bottom of the cell shell at the aluminum outlet and flue end. These windows occupy extremely narrow spaces, making it difficult to insert or accurately aim a conventional handheld temperature gun at the target measurement point, thus hindering the accurate acquisition of the cell shell's actual temperature. This measurement predicament directly leads to safety hazards: when the cell shell temperature rises abnormally, the inability to monitor it promptly and accurately can delay the assessment of equipment malfunctions or abnormal electrolytic reactions, potentially resulting in equipment damage, decreased production efficiency, or even more serious safety accidents. Summary of the Invention

[0004] In view of this, this application provides a temperature measurement device for use in confined spaces. Its main purpose is to enable convenient and accurate measurement of the temperature of the target measurement part in a confined space, so as to ensure the normal operation and safety of industrial production, equipment maintenance and other scenarios.

[0005] To achieve the above objectives, this application mainly provides the following technical solutions:

[0007] Optionally, the temperature sensor is rotatably mounted on the second end of the elongated bracket via a rotating connection structure, and the temperature sensor can rotate relative to the elongated bracket about the axis of the rotating connection structure.

[0008] Optionally, the temperature sensor has a rotation range of 120 degrees relative to the elongated bracket about the axis of the rotating connection structure. The rotation range is based on the state where the detection end of the temperature sensor is perpendicular to the elongated bracket, and can rotate 60 degrees toward the elongated bracket and 60 degrees away from the elongated bracket.

[0012] Optionally, the non-hinged end of the adjustment handle is the end of the adjustment handle away from the hinge point between the adjustment handle and the elongated bracket; the non-bracket connection end of the temperature sensor is the end of the temperature sensor away from the rotational connection point between the temperature sensor and the elongated bracket.

[0013] Optionally, the temperature measuring device for use in confined spaces further includes:

[0014] A bidirectional force spring is provided, which is disposed between the adjusting handle and the grip handle. One end of the bidirectional force spring is connected to the grip handle, and the other end is connected to the adjusting handle.

[0015] Optionally, when the adjusting handle is not rotated relative to the elongated bracket, the bidirectional force spring is in a naturally extended state, and the detection end of the temperature sensor is perpendicular to the elongated bracket.

[0016] Optionally, when the adjustment handle is rotated toward the grip handle, the bidirectional force spring switches from the naturally extended state to the compressed state, the detection end of the temperature sensor rotates toward the elongated bracket, and the angle between the detection end of the temperature sensor and the elongated bracket gradually decreases.

[0017] Optionally, when the adjustment handle is rotated away from the grip handle, the bidirectional force spring switches from the naturally extended state to the stretched state, the detection end of the temperature sensor rotates away from the elongated bracket, and the angle between the detection end of the temperature sensor and the elongated bracket gradually increases.

[0018] Optionally, the display device includes a display screen and a power module, wherein the power module is electrically connected to the display screen and the temperature sensor respectively to supply power to the display screen and the temperature sensor.

[0023] The temperature measuring device for use in confined spaces provided in this application has its wires threaded through the hollow structure of a long strip bracket, which avoids the risk of the exposed wires being snagged or worn by components in the confined space, thus extending the service life of the temperature measuring device and reducing measurement interruptions caused by wire failure.

[0024] The temperature measurement device for narrow spaces provided in this application has a display device fixed on the handle. Operators do not need to insert the probe and then bend over or get close to view the data.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0032] See Figure 1 As shown, according to an embodiment of this application, a temperature measuring device for use in confined spaces is provided, including a long strip support 1, which has a hollow structure; a handle 2 is provided at the first end of the long strip support 1, and a display device 3 is fixedly provided on the handle 2; a temperature sensor 4 is provided at the second end of the long strip support 1, and the temperature sensor 4 and the display device 3 are connected by a wire 5, which passes through the hollow structure of the long strip support 1.

[0033] The temperature measuring device provided in the embodiments of this application for narrow space applications has a long strip bracket 1 that can easily extend into narrow spaces such as the small window of the aluminum outlet end of the electrolytic cell and the flue end of the cell shell, avoiding the problem that conventional handheld temperature guns cannot enter due to size limitations.

[0034] The temperature measuring device for narrow space applications provided in the embodiments of this application has a temperature sensor 4 directly fixed at the second end of the elongated bracket 1, which can accurately align with the target measurement part, avoiding measurement errors caused by alignment deviations in conventional equipment and ensuring the accuracy of temperature data.

[0035] The temperature measuring device provided in the embodiments of this application for use in narrow spaces has a handle 2 at the first end of the long strip bracket 1, which is ergonomically designed. The operator can hold the handle 2 to stably control the temperature measuring device, which makes it easy to adjust the position and angle of the temperature sensor 4 in narrow spaces and reduces the difficulty of operation.

[0036] In the embodiments of this application, the temperature measuring device for use in confined spaces provides a wire 5 that is threaded through the hollow structure of the elongated support 1. This avoids the risk of the wire 5 being exposed and potentially snagged or worn by components in the confined space, thus extending the service life of the temperature measuring device and reducing measurement interruptions caused by wire 5 failure.

[0037] The temperature measuring device provided in the embodiments of this application for use in narrow spaces has a display device 3 fixed on the handle 2. The operator does not need to insert the probe and then bend over or get close to view the data. The temperature can be read directly at the hand position, which reduces the operation actions in complex industrial environments and improves operation safety.

[0038] The elongated bracket 1, serving as the main support structure of the temperature measuring device, has a width of 10 to 30 mm and a slender shape, making it suitable for measurement in confined spaces. In practical applications, the elongated bracket 1 can easily extend into narrow areas, solving the problem of conventional temperature measuring equipment being too large to fit. Simultaneously, the elongated bracket 1 has a certain length and can be designed to specific dimensions, such as 30 to 100 cm, to meet the depth requirements of different confined spaces. This ensures that in scenarios such as small windows in electrolytic cells, it can reach the target measurement point without limiting the measurement range due to insufficient length. This allows operators to control the temperature sensor 4 to the designated position simply by holding the handle 2, without needing to extend their arms or bodies into dangerous confined spaces. This expands the measurement coverage and avoids direct contact between the human body and high-temperature equipment or sharp parts in confined spaces, further enhancing operational safety.

[0039] Specifically, the elongated bracket 1 is hollow and open at both ends. Its internal cavity can accommodate the wires 5 connecting the temperature sensor 4 and the display device 3, thus protecting the wires 5 from being snagged, worn, or affected by environmental interference in the confined space. Here, the wires 5 have a multi-strand composite structure, including a signal transmission line for transmitting the signals collected by the temperature sensor 4, and a power supply line for powering the temperature sensor 4.

[0040] The long, narrow support 1 has a handle 2 at one end, which is the end where the operator holds the long, narrow support 1. The handle 2 makes it easier for the operator to hold the long, narrow support 1 stably and accurately control the position and angle of the temperature sensor 4 at the other end, which is especially flexible when adjusting the measurement point in a confined space.

[0041] The handle 2 is equipped with a display device 3, which displays the temperature data detected by the temperature sensor 4 in real time. This allows operators to read the data directly from their hand without having to put their hands into confined spaces or get too close to observe, improving both ease of operation and safety.

[0042] A temperature sensor 4 is installed at the second end of the elongated support 1, specifically at the end of the support 1 that extends into the narrow space. The temperature sensor 4 is a component that directly contacts or aligns with the target measurement area, used to collect temperature signals. Its position at the end of the support 1 extending into the narrow space allows for close and precise alignment with the target measurement area, reducing measurement errors. Here, the temperature sensor 4 is an infrared temperature sensor, enabling non-contact temperature measurement without direct contact with the target measurement area. This avoids wear or damage caused by direct contact between the temperature sensor 4 and the high-temperature tank shell, sharp parts, etc., extending its service life. Furthermore, for narrow spaces such as electrolytic cells where high temperatures and corrosive environments may exist, non-contact measurement reduces performance degradation caused by prolonged exposure to harsh environments, ensuring the stability of measurement accuracy.

[0043] Specifically, the temperature sensor 4 is connected to the display device 3 via a wire 5, forming a signal transmission path. In use, the operator holds the handle 2 and inserts the second end of the elongated bracket 1, which carries the temperature sensor 4, into a narrow space, such as the small window of an electrolytic cell, aligning the temperature sensor 4 with the target measurement area. The temperature signal collected by the temperature sensor 4 is transmitted through the wire 5 inside the elongated bracket 1 to the display device 3 on the handle 2, allowing the operator to directly read the temperature data, achieving convenient and accurate temperature measurement of the target within a narrow space. Here, the target measurement area is the electrolytic cell shell.

[0044] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the temperature sensor 4 is rotatably mounted on the second end of the elongated bracket 1 via the rotating connection structure 6, and the temperature sensor 4 can rotate relative to the elongated bracket 1 about the axis of the rotating connection structure 6.

[0045] In this embodiment, the rotatable temperature sensor 4 can be accurately aligned with the target measurement part hidden behind a corner or gap, avoiding the inability to align with the target measurement part due to limited viewing angle.

[0046] The rotating connection structure 6 is an intermediate component between the temperature sensor 4 and the second end of the elongated bracket 1. It can be understood as a hinge, rotating shaft, or damping shaft, etc. One end is fixedly connected to the second end of the elongated bracket 1, and the other end is fixedly connected to the temperature sensor 4, forming a movable connection fulcrum. Thus, the temperature sensor 4 can rotate relative to the elongated bracket 1 around the axis of the rotating connection structure 6. For example, it can achieve directional rotation within an angle range of 0° to 180°, and will not detach from the elongated bracket 1 during rotation, maintaining a stable mechanical connection and signal transmission. Here, the wire 5 can be connected through a reserved channel inside the rotating connection structure 6, avoiding pulling on the wire 5 during rotation.

[0047] Specifically, in practical applications, when the long strip bracket 1 is inserted into a narrow space, the temperature sensor 4 can be rotated to quickly switch the measurement angle for multiple measurement points in different directions within the narrow space, reducing the repeated insertion and removal of the long strip bracket 1 and improving measurement efficiency.

[0048] In the above embodiment, the temperature sensor 4 rotates 120 degrees relative to the elongated bracket 1 about the axis of the rotating connection structure 6. The rotation range is based on the state where the detection end of the temperature sensor 4 is perpendicular to the elongated bracket 1. It can rotate 60 degrees towards the elongated bracket 1 and 60 degrees away from the elongated bracket 1.

[0049] Specifically, when the sensing end of the temperature sensor 4 is at a 90° right angle to the length direction of the elongated bracket 1, this is the initial reference position for rotation. For example, if the elongated bracket 1 is horizontally extended, the sensing end of the temperature sensor 4 will be perpendicular to the elongated bracket 1 and extend outward.

[0050] Specifically, in practical applications, the detection end of temperature sensor 4 rotates 60° from its initial reference position toward the elongated support 1 itself, reducing the angle between the detection end of temperature sensor 4 and the elongated support 1 to 30°. At this point, temperature sensor 4 is closer to the elongated support 1, making it suitable for measuring target areas on the side or rear of the elongated support 1. Alternatively, the detection end of temperature sensor 4 can rotate 60° from its initial reference position away from the elongated support 1, increasing the angle between the detection end of temperature sensor 4 and the elongated support 1 to 150°. At this point, temperature sensor 4 is more outwardly positioned, making it suitable for measuring target areas slightly to the outside of the front of the elongated support 1.

[0051] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1As shown, the temperature measuring device for use in confined spaces also includes an adjustment handle 7 and an adjustment rod 8; the adjustment handle 7 is hinged to the first end of the elongated support 1, and the adjustment handle 7 can rotate relative to the elongated support 1 about the hinge point between the adjustment handle 7 and the elongated support 1; one end of the adjustment rod 8 is hinged to the non-hinged end of the adjustment handle 7, and the other end is hinged to the non-support connection end of the temperature sensor 4.

[0052] In this embodiment, by setting an adjustment handle 7 and an adjustment rod 8, when the elongated bracket 1 is extended into a narrow space, the operator does not need to directly contact the temperature sensor 4. Simply holding the handle 2 and rotating the adjustment handle 7 will cause the temperature sensor 4 to rotate via the adjustment rod 8. This solves the problem of not being able to manually adjust the angle of the temperature sensor 4 in narrow spaces, making it particularly suitable for scenarios with limited space and where it is difficult to reach in, allowing the temperature sensor 4 to be flexibly aligned with the target measurement area hidden behind corners or gaps.

[0053] Among them, the adjustment handle 7 is a component that can be directly controlled by the operator. It is installed at the first end of the long strip bracket 1 and is connected to the long strip bracket 1 by a hinge.

[0054] The adjusting rod 8 is a slender rod-shaped component that transmits power, with both ends connected by hinges. Here, one end of the adjusting rod 8 is connected to the non-hinged end of the adjusting handle 7; the other end is connected to the non-support connection end of the temperature sensor 4.

[0055] Specifically, in practical application scenarios, when the operator rotates the adjustment handle 7, the adjustment handle 7 rotates around its hinge point with the long strip bracket 1, causing its non-hinged end to move; this movement is transmitted to the non-bracket connection end of the temperature sensor 4 through the adjustment rod 8, forcing the temperature sensor 4 to rotate around its rotational connection structure 6 with the long strip bracket 1; ultimately achieving the linkage effect where the operator rotates the adjustment handle 7 at the near end of the long strip bracket 1, and the temperature sensor 4 synchronously changes its angle at the far end of the long strip bracket 1.

[0056] In the above embodiments, see Figure 1 As shown, the non-hinged end of the adjustment handle 7 is the end of the adjustment handle 7 that is away from the hinge point between the adjustment handle 7 and the elongated bracket 1; the non-bracket connection end of the temperature sensor 4 is the end of the temperature sensor 4 that is away from the rotational connection point between the temperature sensor 4 and the elongated bracket 1.

[0057] The adjustment handle 7 is connected to the elongated bracket 1 by a hinge, which can be understood as a pivot point. The end of the adjustment handle 7 closest to this pivot point is the hinged end, while the opposite end is the non-hinged end. When the operator rotates the adjustment handle 7, the non-hinged end of the adjustment handle 7 will move in an arc around the pivot point, transmitting force to the temperature sensor 4 through the adjustment rod 8, thereby causing the temperature sensor 4 to rotate.

[0058] The temperature sensor 4 is connected to the second end of the elongated bracket 1 via a rotating connection structure 6. The end of the sensor 4 closest to the pivot point is the bracket connection end. The bracket also includes a detection end for acquiring temperature signals and a non-bracket connection end located on the side of the bracket connection end furthest from the detection end. When the adjusting handle 7 moves the adjusting rod 8, the adjusting rod 8 exerts a pushing and pulling force on the non-bracket connection end of the temperature sensor 4, forcing the temperature sensor 4 to rotate about the rotating connection structure 6 as an axis, thereby changing the angle of the detection end.

[0059] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the temperature measuring device for use in confined spaces also includes a bidirectional force spring 9, which is disposed between the adjusting handle 7 and the grip handle 2. One end of the bidirectional force spring 9 is connected to the grip handle 2, and the other end is connected to the adjusting handle 7.

[0060] In this embodiment, when the operator releases the adjustment handle 7, the bidirectional force spring 9 can use its own elasticity to drive the adjustment handle 7 back to its initial position, and simultaneously link the temperature sensor 4 back to the aforementioned initial reference position, eliminating the need for manual adjustment and improving operational convenience. During adjustment, the elasticity of the bidirectional force spring 9 can also provide a stable damping feel for the adjustment handle 7, preventing sudden changes in the angle of the temperature sensor 4 due to fluctuations in operating force, thus facilitating precise angle control. Furthermore, if the temperature sensor 4 accidentally touches an obstacle in a confined space, the bidirectional force spring 9 can absorb the impact force through deformation, reducing the instantaneous stress on the adjustment rod 8, temperature sensor 4, and rotating connection structure 6, lowering the risk of component damage, and extending the service life of the device.

[0061] The bidirectional force-bearing spring 9 has a bidirectional force-bearing characteristic. It is installed between the adjusting handle 7 and the grip handle 2, with one end fixedly connected to the grip handle 2 and the other end fixedly connected to the adjusting handle 7. Here, when the operator rotates the adjusting handle 7, the bidirectional force-bearing spring 9 will deform due to the change in the relative position of the adjusting handle 7 and the grip handle 2, and at the same time generate a reverse elastic force. When the operator releases the adjusting handle 7, the elastic force of the bidirectional force-bearing spring 9 will drive the adjusting handle 7 to automatically return to the initial position, and then drive the temperature sensor 4 back to the aforementioned initial reference position through the adjusting rod 8.

[0062] Specifically, the bidirectional force spring 9 connects the adjusting handle 7 and the grip handle 2, providing elastic constraints for the rotation of the adjusting handle 7, enabling automatic reset after operation, and buffering force changes during operation, making angle adjustment more stable and precise.

[0063] In the above embodiments, see Figure 1 As shown, when the adjusting handle 7 is not rotated relative to the long strip bracket 1, the bidirectional force spring 9 is in a naturally extended state, and the detection end of the temperature sensor 4 is perpendicular to the long strip bracket 1.

[0064] Here, when the adjusting handle 7 does not rotate relative to the elongated bracket 1, the temperature measuring device is in its initial state. In this initial state, the bidirectional force spring 9 is in its natural extended state; that is, the bidirectional force spring 9 is neither stretched nor compressed. At this time, the bidirectional force spring 9 does not generate additional elastic force and only maintains its natural shape. Furthermore, corresponding to the initial state of the adjusting handle 7, the detection end of the temperature sensor 4 is in a position perpendicular to the elongated bracket 1. This position is the aforementioned initial reference position. For example, if the elongated bracket 1 is placed horizontally, then the detection end of the temperature sensor 4 is perpendicular to the elongated bracket 1 and points outward, presenting a 90° angle. It should be noted that this initial state setting provides the operator with a unified starting point for operation. When the operator begins to use the temperature measuring device, they can know the initial angle of the temperature sensor 4 without additional adjustment, facilitating quick operation. At the same time, after each operation, with the help of the bidirectional force spring 9, the adjusting handle 7 and the temperature sensor 4 can automatically return to this initial state, preparing for the next operation and improving the convenience and efficiency of operation.

[0065] In the above embodiments, see Figure 1 As shown, when the adjustment handle 7 is rotated toward the grip handle 2, the bidirectional force spring 9 switches from a naturally extended state to a compressed state, the detection end of the temperature sensor 4 rotates toward the elongated bracket 1, and the angle between the detection end of the temperature sensor 4 and the elongated bracket 1 gradually decreases.

[0066] Here, when the operator actively rotates the adjusting handle 7 towards the grip handle 2, that is, when the operator holds the grip handle 2 and drives the adjusting handle 7 towards the palm, the distance between the grip handle 2 and the adjusting handle 7 decreases, and the bidirectional force spring 9 between the grip handle 2 and the adjusting handle 7 is compressed. At this time, the compressed bidirectional force spring 9 generates a reverse elastic force, that is, a force attempting to return to its natural state, storing energy for the subsequent reset action. Furthermore, since the adjusting handle 7 is connected to the non-bracket connection end of the temperature sensor 4 through the adjusting rod 8, when the adjusting handle 7 rotates, the pulling force is transmitted to the temperature sensor 4 through the adjusting rod 8, forcing the temperature sensor 4 to rotate around its rotational connection structure 6 with the elongated bracket 1. Specifically, the detection end of the temperature sensor 4 rotates towards the elongated bracket 1, that is, the detection end of the temperature sensor 4 moves closer to the elongated bracket 1 from the aforementioned initial reference position, ultimately resulting in a gradual decrease in the angle between the detection end of the temperature sensor 4 and the elongated bracket 1. For example, it gradually decreases from 90° to 30°. It should be noted that this linkage mechanism allows the operator to precisely control the angle of the distal temperature sensor 4 at the near end of the elongated support 1, i.e., the gripping end, through simple hand movements, such as squeezing the adjustment handle 7 and the grip handle 2. This brings the sensor's detection end closer to the elongated support 1, thus adapting to target measurement locations hidden on the side or rear of the elongated support 1 in narrow spaces. This avoids the problem of misalignment due to limited viewing angle and improves measurement flexibility. At the same time, the damping force generated by compressing the bidirectional force spring 9 stabilizes the operating force, prevents sudden angle changes, and ensures alignment accuracy.

[0067] In the above embodiments, see Figure 1 As shown, when the adjustment handle 7 is rotated away from the grip handle 2, the bidirectional force spring 9 switches from a naturally extended state to a stretched state, the detection end of the temperature sensor 4 rotates away from the elongated bracket 1, and the angle between the detection end of the temperature sensor 4 and the elongated bracket 1 gradually increases.

[0068] Here, when the operator rotates the adjustment handle 7 away from the grip handle 2, that is, when the operator holds the grip handle 2 and drives the adjustment handle 7 to rotate outward from the palm, the distance between the grip handle 2 and the adjustment handle 7 increases, and the bidirectional force spring 9 between the grip handle 2 and the adjustment handle 7 is stretched. At this time, the stretched spring generates a contraction force, that is, a force attempting to return to its natural state, which provides damping for operation and stores energy for subsequent reset. Furthermore, since the adjustment handle 7 is connected to the non-bracket connection end of the temperature sensor 4 through the adjustment rod 8, the rotation of the adjustment handle 7 will transmit a thrust to the temperature sensor 4 through the rod, forcing the temperature sensor 4 to rotate around its rotational connection structure 6 with the elongated bracket 1. Specifically, the detection end of the temperature sensor 4 rotates away from the elongated bracket 1, that is, the detection end of the temperature sensor 4 opens outward from the aforementioned initial reference position. Ultimately, this manifests as the angle between the detection end of the temperature sensor 4 and the elongated bracket 1 gradually increasing. For example, it gradually increases from 90° to 150°. It should be noted that this mechanism allows operators to easily extend the temperature sensor 4 at the remote end through simple hand movements, such as pushing open the adjustment handle 7, to accommodate the target measurement area located slightly outside the front of the elongated bracket 1 in confined spaces. This eliminates the need for repeated insertion and removal of the elongated bracket 1, allowing for angle adjustment to cover more measurement points and improving operational efficiency. Simultaneously, the damping of the bidirectional tension spring 9 stabilizes the operating force, preventing alignment deviations caused by sudden angle changes and ensuring measurement accuracy.

[0069] In some possible embodiments disclosed in this application, the display device 3 includes a display screen and a power module, the power module being electrically connected to the display screen and the temperature sensor 4 respectively, to supply power to the display screen and the temperature sensor 4.

[0070] In this embodiment, the display screen is a key component for human-computer interaction, used to display temperature data or device status, and the temperature sensor 4 is the core component for collecting temperature signals; both require electrical power. The power module is electrically connected to both, ensuring that they receive continuous power during device operation and preventing data acquisition failures or display abnormalities due to power outages. This fundamentally guarantees the realization of the device's core functions.

[0071] Here, a single power module powers both the display screen and the temperature sensor 4. Compared to configuring separate power supplies for each, this reduces the number of components such as power interfaces and wires 5 in the circuit, simplifying the overall circuit structure. This not only reduces the size and weight of the device but also reduces the complexity of wiring connections, helping to improve the integration and space utilization of the temperature measurement device, making it particularly suitable for miniaturized and portable applications.

[0072] In some possible embodiments disclosed in this application, the lengths of the elongated support 1 and the adjusting rod 8 are adjustable.

[0073] In this embodiment, by making the lengths of the elongated support 1 and the adjusting rod 8 adjustable, the temperature measuring device can adapt to different usage scenarios and detection requirements. For example, when detecting the temperature in narrow spaces of different depths, the length of the elongated support 1 can be adjusted to allow the detection end of the temperature sensor 4 to be more accurately aligned with the detection target; while the change in the length of the adjusting rod 8 can be coordinated with the elongated support 1 to adjust the force balance or movement trajectory of the overall structure of the temperature measuring device, ensuring that the temperature measuring device can still work stably under different detection environments.

[0074] Both the elongated support 1 and the adjusting rod 8 can be composed of multiple sections, with adjacent sections connected by a telescopic locking structure. Here, the diameter of one section is slightly smaller than the other, allowing it to partially slide into the other section to achieve length adjustment. The telescopic locking structure is used to fix the relative position of the two adjacent sections after adjustment to the target length, preventing length shift due to force or vibration during use.

[0075] Specifically, the telescopic locking structure can be a spring-loaded snap-on type, a threaded locking type, or a knob locking type, etc., and this application does not limit it in this regard. Taking the telescopic locking structure as a spring-loaded snap-on type as an example, one end of one of the two adjacent long rods is provided with a spring-loaded protruding snap-on, and the inner wall of the other long rod is provided with multiple positioning holes spaced apart along the length direction.
