[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0035] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0036] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] Tailless screw inserts are also called wire screw inserts without mounting handles, which are a type of wire screw inserts (threaded wire inserts). Wire screw inserts are an internally threaded fastener, which is a spring-shaped internal and external threaded concentric body made of high-strength, high-precision, smooth-surfaced cold-rolled stainless steel wire. They are mainly used to enhance and protect the internal threads of low-strength materials. The principle is to form an elastic connection between the screw and the internal thread of the body, eliminate thread manufacturing errors, and improve the connection strength. In the related art, the installation of traditional tailless screw inserts is usually manual, and the manual installation of tailless screw inserts relies on manual labor, which is slow and prone to errors, resulting in unstable installation quality and low installation efficiency.

[0039] Reference Figures 1 to 3 In order to solve the above problems, the present application proposes a tailless screw insert installation tool 100. In an embodiment of the present application, the tailless screw insert installation tool 100 includes a connecting body 10 and a driving host 20.

[0040] The connecting body 10 is used to connect with the tailless screw sleeve 200. It is understandable that the inner side of the tailless screw sleeve 200 is provided with a mounting groove 201, and the connecting body 10 can be engaged with the mounting groove 201, so that the connecting body 10 can drive the tailless screw sleeve 200 to be installed.

[0041] The driving host 20 includes a housing 21, a driving member 22 and a controller 23. Among them, the housing 21 is used for users to hold, and the housing 21 is used to carry and protect components such as the driving member 22 and the controller 23. The housing 21 can be made of non-metallic materials such as plastic materials, so that the housing 21 can meet the ability of various tests such as falling, twisting and sitting pressure without being damaged, and at the same time avoid the mass of the housing 21 being too large, so that the user can hold it for use. It should be noted that the material of the housing 21 is not limited to a certain one, and the commonly used housing 21 materials in the field can be applied to the embodiments of the utility model, which are not listed here one by one. In addition, the outer wall surface of the housing 21 is provided with a button 26, which can be a physical button 26, or a virtual button 26 with a font, symbol or pattern or other identification structure set on the outer surface of the housing 21, so that the user can identify and press it. The structure of the button 26 is electrically connected to the controller 23, so that the user can control the controller 23 through the button 26 area, such as starting or stopping, or controlling the adjustment of the rotation direction of the drive shaft 221 of the driving member 22. It should be noted that the shape of the button 26 area varies with the shape of the shell 21. For example, when the shell 21 is a rectangular parallelepiped, the pressing area should be a square ring structure. When the shell 21 is a cylinder 114, the button 26 area can be a circular ring, and so on.

[0042] The driving member 22 is transmission-connected to the connecting body 10, and the controller 23 is arranged in the housing 21, and the controller 23 is electrically connected to the driving member 22. The driving member 22 can be a motor, and the motor can be a stepping motor. Of course, the motor can also be a servo motor. The type of the motor is not limited in the embodiment of the present application. In addition, the motor can be electrically connected to the controller 23 through a wire, that is, one end of the wire is electrically connected to the motor, and the other end of the wire is electrically connected to the controller 23, so as to realize the electrical connection between the motor and the controller 23. Of course, the motor can also be electrically connected to the controller 23 through a flexible printed circuit (Flexible Printed Circuit, FPC), and this is not limited in the embodiment of the present application. In the embodiment of the present application, the controller 23 can be a control chip. Of course, the controller 23 can also be a circuit board with a control function. For the specific type of the controller 23, the embodiment of the present application is not limited here.

[0043] The controller 23 controls the driving member 22 to drive the connecting body 10 to rotate along the first direction, so that the tailless screw sleeve 200 is screwed into the threaded hole to be screwed in. That is, the rotation direction along the first direction is the direction in which the external thread of the tailless screw sleeve 200 is screwed into the threaded hole to be screwed in. After the tailless screw sleeve 200 is installed in place, the controller 23 controls the driving member 22 (motor) to drive the connecting body 10 to rotate along the second direction, so that the connecting body 10 is rotated out of the threaded hole, and the first direction and the second direction are oppositely arranged. It should be noted that the moving distance of the tailless screw sleeve 200 can be directly obtained by the sensor to determine whether the installation is in place to feedback to the controller 23 for control, or during the installation process, when the connecting body 10 cannot continue to rotate forward, a large resistance is generated and when the torque of the driving member 22 (motor) is exceeded, so that the drive shaft 221 of the driving member 22 (motor) is blocked, the controller 23 determines the blocking, and automatically controls the driving member 22 to drive the connecting body 10 to rotate along the second direction to exit the threaded hole.

[0044] The tailless screw sleeve installation tool 100 based on the embodiment of the present application includes a connection body 10 and a driving main unit 20, and the driving member 22 is driven by the controller 23 of the driving main unit 20 to realize the rotation of the connection body 10 in the first direction and the second direction. During the installation process, the driving member 22 drives the connection body 10 to rotate along the first direction to screw the tailless screw sleeve 200 into the threaded hole to be screwed in, and after the installation is completed, the driving member 22 drives the connection body 10 to rotate along the second direction again, and the connection body 10 is disengaged from the tailless screw sleeve 200, thereby withdrawing from the threaded hole, ensuring the integrity and reliability of the installation process, so as to realize the automatic installation of the tailless screw sleeve 200. Compared with traditional manual operation, this automated installation method can improve installation efficiency, ensure installation quality, and reduce the demand for manual operation, thereby bringing significant benefits and cost savings in the production process.

[0045] Reference Figures 2 to 4 In some embodiments, the controller 23 controls the rotation speed of the driving member 22 to include a first rotation speed and a second rotation speed, and the first rotation speed is less than the second rotation speed. That is, the first rotation speed is a low-speed rotation, and the second rotation speed is a high-speed rotation. When the tailless screw sleeve 200 begins to be screwed into the threaded hole to be screwed in along the first direction, the connecting body 10 rotates at the first speed, and when the connecting body 10 rotates at least two turns along the first direction, the connecting body 10 rotates at the second speed to install the tailless screw sleeve 200 in place. When the connecting body 10 rotates in the second direction after the tailless screw sleeve 200 is installed in place, the connecting body 10 rotates at the first speed, and when the connecting body 10 rotates at least two turns along the second direction, the connecting body 10 rotates at the second speed to rotate the tailless screw sleeve 200 out of the threaded hole.

[0046] In this installation process, first, when the tailless screw sleeve 200 begins to enter the threaded hole, the driver 22 rotates the connecting body 10 at a relatively low speed for several turns (between two and six turns), and the purpose of doing so is to ensure that the tailless screw sleeve 200 is correctly aligned in the initial stage and gradually enters the threaded hole to improve the accuracy and success rate of the installation. Then, once the tailless screw sleeve 200 enters a certain depth, in order to quickly install it in place, the driver 22 will switch to a higher speed. When the tailless screw sleeve 200 is fully installed in place, in order to safely withdraw the connecting body 10 from the mounting groove 201 of the tailless screw sleeve 200, the driver 22 rotates the connecting body 10 at a relatively low speed again for several turns (between two and six turns). This step is intended to protect the connecting body 10 from damage and extend the life of the tool. Finally, once the connecting body 10 is completely separated from the tailless screw sleeve 200, the driver 22 will completely withdraw the connecting body 10 at a relatively high speed to complete the entire installation process. This series of operations makes the installation smoother and ensures the long-term use of the installation tool.

[0047] Reference Figures 2 to 4 In some structural forms, the connecting body 10 includes an anti-reversal structure 11, a mounting rod 12, a paddle 13 and a compression spring 14. The anti-reversal structure 11 is arranged in the housing 21, and the mounting rod 12 is transmission-connected to the driving shaft 221 of the driving member 22 through the anti-reversal structure 11. The outer wall of the mounting rod 12 is recessed to form a mounting groove 121, and the paddle 13 and the compression spring 14 are both embedded in the mounting groove 121, and the compression spring 14 abuts against the paddle 13 and is at least partially exposed outside the mounting groove 121, and the paddle 13 is used to clamp the mounting groove 201 of the tailless screw sleeve 200. The anti-reversal structure 11 is used to limit the rotation of the driving shaft 221 when the driving host 20 stops supplying power.

[0048] Wherein, the mounting rod 12 can be arranged in a round rod, and a mounting groove 121 is arranged on the mounting rod 12 for the plectrum 13 and the extrusion spring 14 to be installed. The plectrum 13 is engaged with the mounting groove 201 of the tailless screw sleeve 200 under the elastic action of the extrusion spring 14 to improve the stability of the engagement between the plectrum 13 and the tailless screw sleeve 200. By arranging the anti-reversal structure 11, even when the driving member 22 loses power, it can prevent unnecessary rotation caused by insufficient locking force of the driving member 22 during manual installation. Thereby, this tailless screw sleeve installation tool 100 can also play the role of manually installing the tailless screw sleeve 200. Therefore, this tailless screw sleeve installation tool 100 is not only suitable for electric installation, but also can be used for manual installation, which improves its applicability and flexibility.

[0049] Reference Figure 3 , Figure 5 as well as Figure 6Further, the anti-reversal structure 11 includes an inner sleeve 111, a rotating sleeve 112, an outer sleeve 113 and a plurality of cylinders 114. The inner sleeve 111, the rotating sleeve 112 and the outer sleeve 113 are sequentially sleeved from the inside to the outside in the cross section of the shell 21. The outer wall of the outer sleeve 113 is fixedly abutted against the inner wall of the shell 21. The rotating sleeve 112 can rotate relative to the outer sleeve 113. The outer wall of the inner sleeve 111 includes a plurality of inclined surfaces 1111 and a plurality of curved surfaces 1112 arranged in sequence. The curved surfaces 1112 abut against the inner wall of the rotating sleeve 112. A plurality of notches 1121 are opened in the circumference of the rotating sleeve 112. A cylinder 114 is accommodated in a notch 1121, and the cylinder 114 is in rolling contact with the inclined surfaces 1111 of the outer sleeve 113 and the inner sleeve 111 respectively. The inner sleeve 111 is connected to the mounting rod 12, and the rotating sleeve 112 is connected to the driving shaft 221 of the driving member 22.

[0050] The outer sleeve 113 can be fixedly abutted against the inner wall of the housing 21 by forming a flat notch 11311121 on the outer side. The arc surface 1112 of the inner sleeve 111 is concavely provided with a groove 111a, and the surface of the rotating sleeve 112 corresponding to the groove 111a is provided with a protrusion 1122, which can be inserted into the groove 111a. In the embodiment of the present application, the number of the notch 1121 and the number of the cylinder 114 can both be three.

[0051] Therefore, when the driving member 22 is powered normally for driving, the driving shaft 221 of the driving member 22 drives the rotating sleeve 112 to rotate, and the protrusion 1122 of the rotating sleeve 112 abuts against the groove wall of the groove 111a to drive the arc surface 1112 to rotate, and simultaneously drives the three cylinders 114 located in the three notches 1121 to roll between the corresponding inclined surfaces 1111 of the inner sleeve 111 and the inner wall of the outer sleeve 113, so as to realize the rotation of the inner sleeve 111, and then drive the mounting rod 12 connected to the inner sleeve 111 to rotate.

[0052] When installing manually, the user needs to rotate manually to screw the tailless screw sleeve 200 into the threaded hole, so that during the rotation process, the installation rod 12 gives the inner side kit 111 a rotation trend, and the rotation of the inner side kit 111 changes the angle between the inclined surface 1111 and the outer side kit 113, thereby changing the space between the inclined surface 1111 and the outer side kit 113. During the change process, the abutment and limiting of the cylinder 114 forms a resistance to prevent the rotation of the rotating kit 112 and the inner side kit 111, thereby increasing the rotation torque when manually installing the tailless screw sleeve 200, and preventing the lack of locking torque when the driving member 22 is not powered, so as to limit the rotation of the driving shaft 221 of the driving member 22. To ensure the stability of manual installation.

[0053] Reference Figure 3 and Figure 4 Furthermore, at least two rotating bearings 15 are added to the connection body 10. These bearings are stacked and firmly fixed inside the outer sleeve 113, so that the mounting rod 12 can be connected to the outer sleeve 113 through the two rotating bearings 15 and realize rotation. By providing the rotating bearings 15, the rotation of the mounting rod 12 is more stable. At the same time, compared with the single-point support of a single bearing, the use of two rotating bearings 15 is not only more stable, but also can ensure concentricity and improve the stability of rotation. This design can enhance the durability and reliability of the connection body 10, and ensure its stability and long-term performance during use.

[0054] Reference Figures 2 to 4 Optionally, the front end 131 of the paddle 13 is located at the end of the mounting rod 12 away from the anti-reversal structure 11. The connecting body 10 further includes an adjusting nut 16. The outer wall of the mounting rod 12 is provided with an external thread. The adjusting nut 16 is connected to the outer wall of the mounting rod 12 by threading and can be moved closer to or away from the front end 131 of the paddle 13 along the extension direction of the mounting rod 12. The end of the adjusting nut 16 away from the anti-reversal structure 11 is used to abut against the tailless screw sleeve 200. In this way, by adjusting the position of the adjusting nut 16 on the mounting rod 12 to adapt to and abut against tailless screw sleeves 200 of different sizes, this design enables the mounting rod 12 to be suitable for tailless screw sleeves 200 of various lengths, thereby enhancing the versatility and applicability of the product. At the same time, it can be understood that the distance between the adjusting nut 16 and the front end 131 of the paddle 13 is the depth of the tailless screw sleeve 200 in the threaded hole. In this way, by moving the adjusting nut 16, it can be close to or away from the front end 131 of the paddle 13, thereby controlling the depth of the tailless screw sleeve 200 in the threaded hole.

[0055] Furthermore, the connection body 10 also includes a locking nut 17, which is threadedly connected to the outer wall of the mounting rod 12 to abut against one end of the adjusting nut 16 close to the anti-reversal structure 11. The function of the locking nut 17 is to tightly fix the adjusting nut 16 after it is adjusted to the desired position to ensure the stability of the position of the adjusting nut 16. This design effectively prevents the accidental change of the position of the adjusting nut 16 due to vibration or external force during use, thereby ensuring the reliability and stability of the connection body 10. The addition of the locking nut 17 makes the entire assembly structure more solid, prolongs the service life of the connector, and reduces the maintenance cost and frequency.

[0056] Reference Figures 2 to 4In some structural forms, the shell 21 is arranged in a cylindrical shape, and the central axis of the shell 21 is arranged coaxially with the central axis of the connecting body 10. Such a design not only improves the concentricity, but also enhances the comfort and stability of the user's grip. By maintaining the coaxiality of the central axis, the device is more stable during operation, the possibility of misoperation is reduced, and the user experience is improved. This design can also provide a more uniform distribution of force, reduce the user's hand fatigue during operation, and increase the comfort of continuous operation. At the same time, the cylindrical shape of the shell 21 also makes the device more ergonomic, easier to hold and operate, and further enhances the user's operating experience.

[0057] Reference Figures 2 to 4 In some structural forms, the driving host 20 also includes a main battery 24 and a backup battery compartment 25. The main battery 24 is arranged in the housing 21 and is respectively connected to the controller 23 and the driver. The backup battery compartment 25 is detachably connected to the housing 21 and is connected to the controller 23 and the driver. The advantage of this design is that when the main battery 24 is exhausted, the user can use the power provided by the backup battery compartment 25 to continue working. In addition, the detachable connection design of the backup battery compartment 25 makes it more convenient to replace or charge the backup battery. This dual power supply mechanism ensures the continuous use of the device, especially when long-term operation is required or there is no easily accessible charging facility, which can provide additional flexibility and convenience. At the same time, this design also enhances the reliability of the equipment and reduces the risk of work interruption due to power outages.

[0058] Furthermore, the driving host 20 also includes an alarm (not shown) electrically connected to the controller 23, and the alarm is used to send an alarm signal when the power of the backup battery compartment 25 is too low. Specifically, when the remaining power of the backup battery compartment 25 drops to one-tenth of the total power or less, the alarm will issue a reminder to prompt the user to charge in time. The design of this alarm includes at least one of a signal light, a buzzer and a voice broadcast device. The signal light reminds the user by lighting up, the buzzer reminds by emitting a buzzing sound, and the voice broadcast device reports to the user in the form of a human voice. Through the combination of these reminder devices, the user can timely understand the use status of the tailless screw sleeve installation tool 100 and take necessary actions. This diversified alarm method not only improves the user's perception of the device status, but also enhances the interactivity between the user and the device.
