Abstract

This utility model belongs to the field of wrench technology and discloses an intelligent wrench, which includes a body, a clamping module, and a drive module. The intelligent wrench of this utility model uses several clamping members included in the clamping module to form a clamping opening, thereby clamping threaded connectors. Since the clamping members can converge or disperse, thus changing the size of the clamping opening, the intelligent wrench of this utility model can accommodate threaded connectors of different sizes. Furthermore, each clamping member is equipped with a pressure sensor. Therefore, during the tightening process of the threaded connector, this utility model can collectively detect the torque between the clamping module and the threaded connector, thereby detecting the degree of tightening of the threaded connector. This eliminates the risk of the threaded connector being insufficiently tightened or over-tightened due to human error, thus ensuring product quality.

Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to an intelligent wrench. Background Technology

[0002] A wrench is a tool designed based on the lever principle. It is commonly used to tighten or loosen bolts, screws, nuts, or other threaded fasteners, and is therefore widely used in installation and disassembly operations.

[0003] As described above, in existing technologies, the end of a wrench is provided with a receiving hole, which forms the clamping jaw of the wrench. Threaded connectors can be placed in the receiving hole and clamped by the end of the wrench. To accommodate threaded connectors of different sizes, the clamping width of the wrench can be manually adjusted within a certain range. However, this manual adjustment method is not only time-consuming but also labor-intensive. To address this issue, existing technologies have developed wrenches with automatically adjustable clamping widths. However, these wrenches only have the function of automatically adjusting the clamping width to match threaded connectors of different sizes; they lack the ability to detect the tightness of the threaded connector during tightening. Therefore, in practical applications, threaded connectors may still be at risk of being insufficiently tightened or over-tightened due to human error. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent wrench that can automatically adjust the clamp width to match threaded connectors of different sizes, and can detect the tightness of the threaded connectors during the tightening process, thereby eliminating the risk that the threaded connectors are not tightened enough or are over-tightened due to human error.

[0005] To achieve this objective, one embodiment of this utility model adopts the following technical solution:

[0006] Smart wrenches, including:

[0007] The main body has a clamping opening at one end, and the main body is provided with a button module;

[0008] A clamping module is disposed at the end of the body. The clamping module includes a plurality of clamping members, which together form the clamping opening and are all slidably mounted on the body. Each clamping member is provided with a pressure sensor. The pressure sensor can detect the pressure between the clamping member and the threaded connector when the clamping module clamps the threaded connector.

[0009] The drive module is capable of driving several of the clamping components to converge or disperse. The drive module is communicatively connected to the button module and the pressure sensor.

[0010] In some embodiments, the drive module includes a drive arm and a drive component. The drive component is connected to a plurality of clamping components via the drive arm and is capable of driving the plurality of clamping components to move synchronously.

[0011] In some embodiments, the driving arm is a multi-link mechanism, and the motion of the driving member is transmitted to a plurality of the clamping members through the multi-link mechanism.

[0012] In some embodiments, all the clamping members are provided with movable plates opposite each other, and a spring is installed between the movable plate and the body. All the movable plates are connected in series to form the driving force arm. The pressure sensor is supported between the corresponding clamping member and the movable plate. The two middle movable plates are connected to the movable end of the driving member through a transmission member. The transmission member can move toward or away from the driving force arm.

[0013] In some embodiments, springs are provided on both sides of the pressure sensor in a direction perpendicular to the arrangement direction of the clamping member and the moving plate.

[0014] In some embodiments, the movable end of the drive member is rotatable about its axis, the movable end of the drive member is provided with a wave groove, the wave groove surrounds the outer periphery of the movable end of the drive member, one end of the transmission member is inserted into the wave groove, and the other end of the transmission member is fixedly connected to the drive arm.

[0018] In some embodiments, the smart wrench is provided with clamping modules at both ends, and each clamping module is provided with a corresponding drive module.

[0019] The beneficial effects of this utility model are:

[0020] In one embodiment of the intelligent wrench of this invention, a clamping jaw is formed by several clamping members included in the clamping module, thereby clamping the threaded connector. Since the clamping members can converge or disperse, thus changing the size of the clamping jaw, the intelligent wrench of this invention can accommodate threaded connectors of different sizes. Furthermore, each clamping member is equipped with a pressure sensor. Therefore, during the tightening process of the threaded connector, this invention can collectively detect the torque between the clamping module and the threaded connector, thereby detecting the degree of tightening of the threaded connector. This eliminates the risk of the threaded connector being insufficiently tightened or over-tightened due to human error, thus ensuring product quality. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] Please see Figures 1 to 7 This embodiment provides an intelligent wrench, which includes a body, a clamping module 3 and a driving module 4. The body has a clamping opening 11 at its end. Specifically, the intelligent wrench includes a head 51 and a handle 52. The clamping opening 11 is formed at the head 51. The wrench can be fitted onto the outer periphery of the threaded connector through the clamping opening 11. The operator can tighten the threaded connector by holding the handle 52 and rotating the handle 52 around the center point of the clamping opening 11.

[0041] As described above, the clamping module 3 is disposed at the end of the main body, and the clamping module 3 includes a plurality of clamping members 31, which together form a clamping opening 11 and are all slidably mounted on the main body. Specifically, the end of the main body is provided with a receiving hole for accommodating threaded connectors, the clamping opening 11 is formed in the receiving hole, and the wall of the receiving hole is provided with a plurality of sliding grooves 14, in which a clamping member 31 is installed, and the clamping member 31 can move along the opening direction of the sliding groove 14.

[0042] Thus, the clamping elements 31 can be brought together or dispersed. Specifically, the drive module 4 can drive the clamping elements 31 to be brought together or dispersed. When the clamping elements 31 are brought together, the size of the clamping opening 11 is reduced, which makes it suitable for clamping smaller threaded connectors. When the clamping elements 31 are dispersed, the size of the clamping opening 11 is increased, which makes it suitable for clamping larger threaded connectors.

[0043] In addition, all clamping components 31 are equipped with pressure sensors 32. The pressure sensors 32 can detect the pressure between the clamping component 31 and the threaded connector when the clamping module 3 clamps the threaded connector, thereby ensuring that the clamping module 3 can firmly clamp the threaded connector.

[0044] In addition, the smart wrench also includes a processing circuit that is electrically connected to all pressure sensors 32. When the smart wrench tightens the threaded connector, it calculates the torque between the clamping module 3 and the threaded connector based on the detection data of all pressure sensors 32. Specifically, during the process of the operator tightening the threaded connector with the smart wrench, each pressure sensor 32 can detect the pressure between its corresponding clamping component 31 and the threaded connector. The processing circuit integrates the detection data of all pressure sensors 32 and can calculate the torque between the clamping module 3 and the threaded connector accordingly.

[0045] For example, in this embodiment, after the clamping module 3 securely clamps the M8 bolt, the operator holds the middle position of the handle 52 and applies a tightening force of 300N to the bolt. That is, the pressure sensor 32 detects that the pressure between the corresponding clamping member 31 and the bolt is 300N. Furthermore, the distance between the middle position of the handle 52 and the center position of the clamping jaw 11 is 15cm. Therefore, the torque generated between the clamping module 3 and the threaded connector is F = 100N * 15cm = 4500N·cm = 4.5N·m. Thus, in this embodiment, the torque between the clamping module 3 and the bolt is calculated by the processing circuit to be 4.5N·m.

[0046] Furthermore, the drive module 4 is communicatively connected to the button module 2 and the pressure sensor 32. Specifically, in this embodiment, the smart wrench also includes a control panel 71, and the drive module 4, button module 2, and pressure sensor 32 are all electrically connected to the control panel 71, thereby enabling the drive module 4 to communicate with the button module 2 and the pressure sensor 32.

[0047] It is understood that the processing circuit is a circuit module arranged on the control panel 71, and includes a processor chip, memory, and other structures. Since the specific structure of the processing circuit is existing technology, it will not be described in detail in this embodiment.

[0048] Based on the above, the smart wrench in this embodiment forms a clamping opening 11 by means of several clamping members 31 included in the clamping module 3, thereby clamping the threaded connector. Since the several clamping members 31 can converge or disperse, thereby changing the size of the clamping opening 11, the smart wrench in this embodiment can match threaded connectors of different sizes. Moreover, each clamping member 31 is provided with a pressure sensor 32. Thus, during the tightening process of the threaded connector, all pressure sensors 32 can jointly detect the torque between the clamping module 3 and the threaded connector, thereby detecting the degree of tightening of the threaded connector, eliminating the risk of the threaded connector being insufficiently tightened or over-tightened due to human error, and thus ensuring product quality.

[0049] It is understood that, similar to wrenches in the prior art, in this embodiment, both ends of the smart wrench are provided with clamping openings 11, that is, both ends of the smart wrench are provided with clamping modules 3, and all clamping modules 3 are provided with corresponding drive modules 4, so that when working with either end, it can match threaded connectors of different sizes, and can detect the tightness of the threaded connectors during the tightening process.

[0050] Specifically, in one embodiment, the smart wrench includes a head 51 and a handle 52. Both ends of the handle 52 are provided with a head 51. Each of the two heads 51 is provided with a receiving hole. Each of the two receiving holes is provided with a clamping module 3, thereby forming a clamping opening 11 at each of the two receiving holes.

[0051] For example, in one embodiment, the receiving holes at both ends of the smart wrench are hexagonal holes. Taking the first receiving hole 12 and the second receiving hole 13 as examples, the following description is provided.

[0052] As described above, an opening 121 is provided on one side of the first receiving hole 12, so that the hole wall of the first receiving hole 12 has four surfaces, and a sliding groove 14 is provided on each surface, so that a clamping member 31 is slidably installed on each surface. That is, in this embodiment, the clamping module 3 corresponding to the first receiving hole 12 includes four clamping members 31, and the clamping opening 11 formed by the four clamping members 31 is the first clamping opening.

[0053] When the operator uses the first clamp for operation, the four clamping members 31 that form the first clamp can converge or disperse, thereby adjusting the size of the first clamp. The threaded connector can be moved into the first clamp through the opening 121 and clamped by the four clamping members 31. Then, the operator can rotate the operating handle 52 around the center point of the first clamp to tighten the threaded connector. During the tightening process, the four pressure sensors 32 can work together to detect the torque between the clamping module 3 and the threaded connector. When the torque meets the requirements, the operator stops tightening the threaded connector.

[0054] The second receiving hole 13 is a closed sleeve hole, that is, the hole wall of the second receiving hole 13 has six sides, and each side is provided with a sliding groove 14, so that each side is slidably installed with a clamping member 31. That is, in this embodiment, the clamping module 3 corresponding to the second receiving hole 13 includes six clamping members 31, and the clamping opening 11 formed by the six clamping members 31 is the second clamping opening.

[0055] When the operator uses the second clamp, the six clamping members 31 forming the second clamp can converge or disperse to adjust the size of the second clamp. The threaded connector can be moved into the second clamp from the bottom of the second threaded hole and clamped by the six clamping members 31. Then, the operator can rotate the operating handle 52 around the center point of the second clamp to tighten the threaded connector. During the tightening process, the six pressure sensors 32 work together to detect the torque between the clamping module 3 and the threaded connector. When the torque meets the requirements, the operator stops tightening the threaded connector.

[0056] It is understandable that the maximum size of the first clamping opening is the same as the size of the first receiving hole 12, and the maximum size of the second clamping opening is the same as the size of the second receiving hole 13. For the first receiving hole 12, the size of the first clamping opening decreases when the four clamping members 31 converge and extend into the first receiving hole 12, and reaches its maximum size when the four clamping members 31 disperse and completely retract into the body. Correspondingly, for the second receiving hole 13, the size of the second clamping opening decreases when all six clamping members 31 converge and extend into the second receiving hole 13, and reaches its maximum size when all six clamping members 31 disperse and completely retract into the body.

[0057] Based on the above description, in this embodiment, the button module 2 includes a power switch button 21, a manual convergence button 22, and a manual divergence button 23. The operator can control the control panel 71 to turn on or off by pressing the power switch button 21.

[0058] After the control panel 71 is powered on, the operator can press the manual convergence button 22 to control all the clamping parts 31 of the clamping module 3 to converge, and correspondingly, the operator can press the manual dispersal button 23 to control all the clamping parts 31 of the clamping module 3 to disperse.

[0059] Understandably, operators need to press and hold the manual convergence button 22 or the manual divergence button 23 to adjust the clamp 11 to the appropriate size.

[0060] It is worth noting that the two clamping modules 3 operate simultaneously, but only one of the clamping ports 11 holds the bolt connector.

[0061] As described above, in one embodiment, the smart wrench has a manual mode. In manual mode, if the bolt connector is small in size and the clamping jaw 11 is large in size, the operator can place the bolt connector in one of the receiving holes and press and hold the manual convergence button 22 to bring together all the clamping parts 31 included in the clamping module 3 until the threaded connector is clamped. When the pressure sensor 32 detects that the pressure between the clamping part 31 and the threaded connector is equal to the first preset value, the smart wrench will issue a reminder signal to prompt the operator. The operator will then stop pressing the manual convergence button 22 and operate the smart wrench to tighten the threaded connector. During the tightening process, when the pressure sensor 32 detects that the torque between the clamping module 3 and the threaded connector is equal to the second preset value, the smart wrench will issue a reminder signal to prompt the operator. At the same time, all the clamping parts 31 included in the clamping module 3 will disperse, and the work will end.

[0062] Correspondingly, if the bolt connector is large in size and the clamp 11 is small in size, the operator can press and hold the manual release button 23 to release all the clamping parts 31 included in the clamping module 3. Then, after placing the bolt connector in one of the receiving holes, the operator presses and holds the manual convergence button 22 until the threaded connector is clamped and the pressure sensor 32 detects that the pressure between the clamping part 31 and the threaded connector is equal to the first preset value. At this time, the smart wrench will issue a reminder signal to prompt the operator. The operator will then stop pressing the manual convergence button 22 and operate the smart wrench to tighten the threaded connector. During the tightening process, when the pressure sensor 32 detects that the torque between the clamping module 3 and the threaded connector is equal to the second preset value, the smart wrench will issue a reminder signal to prompt the operator. At the same time, all the clamping parts 31 included in the clamping module 3 will release, and the work will end.

[0063] Therefore, this embodiment can adjust the size of the clamp 11 to match threaded connectors of different sizes, and can also prevent the threaded connectors from being not tightened enough or over-tightened.

[0064] It is understood that in other alternative embodiments, each time the pressure sensor 32 detects that the torque between the clamping module 3 and the threaded connector is equal to the second preset value, all the clamping parts 31 included in the clamping module 3 can automatically disperse to fully retract into the body, so that the operator can simply press the manual convergence button 22 for the next operation. This embodiment does not impose specific limitations on this.

[0065] It is worth noting that both the first and second preset values ​​are data stored in the control panel 71 during the manufacturing process of the smart wrench. The first preset value is the same for threaded connectors of different sizes. Since the size range of threaded connectors that the smart wrench is compatible with is small, the second preset value is also the same for threaded connectors of different sizes.

[0066] Of course, in other alternative embodiments, different second preset values ​​can be set for threaded connectors of different sizes, and these values ​​can be stored in the control panel 71 for the smart wrench to recall during operation. Specifically, the control panel 71 can have multiple preset second values, with different data corresponding to threaded connectors of different sizes. Before operation, the operator can select the corresponding second preset value according to the size of the threaded connector to be operated. This embodiment does not impose specific limitations on this.

[0067] Furthermore, in one embodiment, the button module 2 also includes an automatic convergence button 24 and an automatic divergence button 25, meaning the smart wrench also has an automatic mode. In automatic mode, the operator only needs to press the automatic convergence button 24 or the automatic divergence button 25 once, and the smart wrench can automatically control all the clamping parts 31 included in the clamping module 3 to converge or diverge. When the pressure sensor 32 detects that the pressure between the clamping parts 31 and the threaded connector is equal to a first preset value, the smart wrench controls all the clamping parts 31 to stop moving. At the same time, the smart wrench issues a reminder signal to prompt the operator, who can then operate the smart wrench to tighten the threaded connector. During the tightening process, when the pressure sensor 32 detects that the torque between the clamping module 3 and the threaded connector is equal to a second preset value, the smart wrench issues a reminder signal to prompt the operator, and at the same time, all the clamping parts 31 included in the clamping module 3 automatically diverge, and the work ends.

[0068] As such, operators can freely choose between manual or automatic mode for operation.

[0069] Additionally, it should be noted that in this embodiment, the button module 2 includes a button plate 26 and silicone buttons 27. The button plate 26 is exposed above the main body and is equipped with a power switch button 21, a manual convergence button 22, a manual divergence button 23, an automatic convergence button 24, and an automatic divergence button 25. The silicone buttons 27 are supported between the button plate 26 and the control panel 71. The control panel 71 has five contacts 711, which correspond to the power switch button 21, the manual convergence button 22, the manual divergence button 23, the automatic convergence button 24, and the automatic divergence button 25, respectively. When an operator presses any button, the silicone buttons 27 deform and come into contact with the corresponding contact 711, thereby enabling the control panel 71 to receive the button signal and control the drive module 4 to complete the corresponding action.

[0070] Furthermore, the smart wrench also includes an alarm 6, which is electrically connected to the pressure sensor 32. When the pressure between the clamping member 31 and the threaded connector is detected to be equal to a first preset value, the smart wrench emits a warning signal through the alarm 6 to alert the operator. Correspondingly, during tightening, when the pressure sensor 32 detects that the torque between the clamping module 3 and the threaded connector is equal to a second preset value, the smart wrench also emits a warning signal through the alarm 6 to alert the operator.

[0071] For example, in one embodiment, the alarm 6 is a buzzer located inside the main body, thereby emitting a sound to alert the operator. Of course, in other alternative embodiments, the alarm 6 may also be an indicator light located on the outside of the main body; this embodiment does not impose any specific limitations on this.

[0072] As can be seen from the above, in one embodiment, the body includes a first housing 15 and a second housing 16, a groove 14 is formed on the first housing 15 and the second housing 16, and a cavity is formed between the first housing 15 and the second housing 16. The control panel 71, the alarm 6 and the drive module 4 are all installed in the cavity.

[0073] Understandably, the smart wrench also includes a battery 72, which powers the control panel 71 and other structures, and is also installed in the cavity.

[0074] Furthermore, the first housing 15 and the second housing 16 are detachably connected, which facilitates the maintenance of various components inside the main body.

[0075] Furthermore, based on the above description, in this embodiment, the drive module 4 includes a drive arm 41 and a drive component 42. The drive component 42 is connected to several clamping components 31 through the drive arm 41 and can drive several clamping components 31 to move synchronously, thereby enabling precise adjustment of the size of the clamping opening 11.

[0076] Among them, the driving arm 41 is a multi-link mechanism. The movement of the driving member 42 is transmitted to several clamping members 31 through the multi-link mechanism to realize the synchronous movement of several clamping members 31.

[0077] From the above, such as Figures 3 to 7 As shown, all clamping members 31 are provided with moving plates 411 opposite each other. All moving plates 411 are connected in series to form a driving arm 41. The pressure sensor 32 is supported between the corresponding clamping member 31 and the moving plate 411. The two middle moving plates 411 are connected to the moving end of the driving member 42 through a transmission member 44. The transmission member 44 can move toward or away from the driving arm 41. When the transmission member 44 moves toward the driving arm 41, under the action of the transmission member 44, the two middle moving plates 411 can move toward the side closer to the clamping module 3. At the same time, driven by the two middle moving plates 411, the other moving plates 411 on the outside also begin to move toward the side closer to the clamping module 3. Under the action of the pressure sensor 32, all clamping members 31 begin to converge.

[0078] When the transmission component 44 moves away from the driving arm 41, under the action of the transmission component 44, the two middle moving plates 411 can move towards the side away from the clamping module 3. At the same time, driven by the two middle moving plates 411, the other outer moving plates 411 also begin to move towards the side away from the clamping module 3. Driven by the pressure sensor 32, all clamping components 31 begin to separate.

[0079] Please refer to Figure 6For the first receiving hole 12, the transmission member 44 is fixedly connected to one of the two middle moving plates 411 through the first transmission plate 45, and fixedly connected to the other of the two middle moving plates 411 through the second transmission plate 46.

[0080] Therefore, when the transmission component 44 moves toward the driving arm 41, under the action of the transmission component 44, the two middle moving plates 411 can move toward the side closer to the clamping module 3. At the same time, driven by the two middle moving plates 411, the other two outer moving plates 411 also begin to move toward the side closer to the clamping module 3. Under the action of the pressure sensor 32, all the clamping components 31 begin to converge.

[0081] When the transmission component 44 moves away from the driving arm 41, under the action of the transmission component 44, the two middle moving plates 411 can move towards the side away from the clamping module 3. At the same time, driven by the two middle moving plates 411, the other two outer moving plates 411 also begin to move towards the side away from the clamping module 3. Under the action of the pressure sensor 32, all the clamping components 31 begin to separate.

[0082] Additionally, please see Figure 7 For the second receiving hole 13, the transmission member 44 is fixedly connected to the two moving plates 411 in the middle through the third transmission plate 47.

[0083] Therefore, when the transmission component 44 moves toward the driving arm 41, under the action of the transmission component 44, the two middle ones of the six moving plates 411 can move toward the side closer to the clamping module 3. At the same time, driven by the two middle ones of the six moving plates 411, the other four outer moving plates 411 also begin to move toward the side closer to the clamping module 3. Under the action of the pressure sensor 32, all the clamping components 31 begin to converge.

[0084] When the transmission component 44 moves away from the driving arm 41, under the action of the transmission component 44, the two middle ones of the six moving plates 411 can move toward the side away from the clamping module 3. At the same time, driven by the two middle ones of the six moving plates 411, the other four outer moving plates 411 also begin to move toward the side away from the clamping module 3. Under the action of the pressure sensor 32, all the clamping components 31 begin to separate.

[0085] For further information, please refer to [link / reference]. Figures 3 to 7In one embodiment, the movable end of the drive member 42 is rotatable about its axis. The movable end of the drive member 42 is provided with a wave groove 421. The wave groove 421 surrounds the outer periphery of the movable end of the drive member 42. Moreover, one of the two adjacent wave crests 4211 of the wave groove 421 is close to the drive arm 41 along the axial direction of the movable end of the drive member 42, while the other is far away from the drive arm 41 along the axial direction of the movable end of the drive member 42.

[0086] It is understood that in this embodiment, the transmission member 44 is a rod extending radially along the movable end of the drive member 42, and one end of the transmission member 44 is inserted into the wave groove 421, while the other end of the transmission member 44 is fixedly connected to the drive arm 41.

[0087] Therefore, when the driving member 42 drives its movable end to rotate around the axis, under the guidance of the wave groove 421, the transmission member 44 can move forward or backward in a straight line, thereby moving toward or away from the driving arm 41.

[0088] For example, in one embodiment, the axial direction of the movable end of the drive member 42 is parallel to the length direction of the smart wrench. Thus, in one embodiment, the transmission member 44 can move toward or away from the drive arm 41 along the length direction of the smart wrench. When the transmission member 44 moves toward the drive arm 41 along the length direction of the smart wrench, all the clamping members 31 begin to converge under the action of the transmission member 44.

[0089] When the transmission component 44 moves away from the driving arm 41 along the length of the smart wrench, all the clamping components 31 begin to separate under the action of the transmission component 44.

[0090] It is understood that the driving component 42 can be a stepper motor or a servo motor, etc., and this embodiment does not impose specific restrictions on it.

[0091] Furthermore, based on the foregoing description, in one embodiment, the smart wrench includes a head 51 and a handle 52. It is worth noting that the drive element 42 is disposed inside the handle 52, thereby facilitating the arrangement of the clamping module 3 and the drive arm 41 in the head 51.

[0092] In addition, in one embodiment, a spring 43 is installed between the moving plate 411 and the body. Furthermore, springs 43 are provided on both sides of the pressure sensor 32 in a direction perpendicular to the arrangement direction of the clamping member 31 and the moving plate 411. Thus, after the transmission member 44 moves away from the driving arm 41, the moving plate 411 can move accurately toward the side away from the clamping module 3, thereby driving the clamping member 31 to open precisely.

[0093] It is also worth noting that one end of the pressure sensor 32 is a soft ball head 321, which extends out of the clamping member 31 and is located on the side of the clamping member 31 away from the moving plate 411. Thus, the pressure sensor 32 can directly contact the threaded connection, thereby making the detected data more accurate.

[0094] Moreover, since the soft ball head 321 is made of a softer material, it can deform under the compression of the threaded connector, thus not affecting the clamping member 31's ability to clamp the threaded connector.

[0095] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
