Description

Technical Field

[0001] This application relates to the field of electronic pen technology, and more particularly to an electronic pen. Background Technology

[0002] Most electronic pens nowadays have a pressure-sensitive module. This module can detect the amount of pressure applied by the user to the pen tip and convert the pressure data into an electronic signal, thereby enabling dynamic control of the pen's stroke effect.

[0003] The pressure-sensitive module in an electronic pen typically consists of a spring and a support. Pressure applied to the pen tip causes the spring to deform, and the degree of deformation reflects the pressure applied to the pen tip. The support, used to mount the spring, is usually formed by rolling a single sheet of metal. After the sheet is rolled into the support, the seams at the ends need to be welded together to prevent deformation and cracking during installation and use. This means that the support requires both stamping and welding processes, making the manufacturing process complex and resulting in higher production costs for electronic pens. Utility Model Content

Detailed Implementation

[0034] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0035] An electronic pen, also known as a smart pen or digital pen, is an electronic device that enables writing, drawing, or interactive input through digital technology. It is widely used in touch-screen devices such as tablets, graphics tablets, and smartphones. Existing electronic pens include capacitive, electromagnetic, ultrasonic, and hybrid technology pens. Through technologies such as pressure sensitivity, low latency, and tilt recognition, electronic pens can completely replace traditional pen and paper in digital creation and input.

[0036] Most electronic pens nowadays have a pressure-sensitive module. This module detects the pressure applied by the user to the pen tip and converts the pressure data into electronic signals, thereby enabling dynamic control of the pen's stroke effects. For example, by sensing the pressure applied to the pen tip, the pressure-sensitive module can control the thickness, transparency, and color intensity of the lines drawn by the electronic pen, so that the drawing effect can simulate the drawing effect of a real paintbrush as closely as possible.

[0037] The pressure-sensitive module in an electronic pen typically consists of a spring and a support. The spring is connected to the pen tip via a force-transmitting component. When the pen tip is subjected to pressure, the force is transmitted to the spring in the pressure-sensitive module, causing it to deform accordingly. The degree of deformation of the spring reflects the pressure on the pen tip, and the pressure data can be obtained by detecting the degree of deformation. The support is a supporting structure inside the electronic pen used to mount the spring. To accommodate the shape of the electronic pen, the support is generally formed by rolling a single sheet of metal. After the sheet is rolled into the support, there is a seam between the two opposite ends. To prevent cracking and deformation at the seam during installation and use, technicians need to weld the seam together. This means that the support forming process requires stamping and welding, which is complex and relatively expensive, thus increasing the overall production cost of electronic pens.

[0038] To address the aforementioned issues, this application proposes an electronic pen.

[0039] Example 1

[0040] Embodiment 1 of this application provides an electronic pen. (See reference...) Figure 1 The electronic pen has a stand 1 and a connector 2.

[0041] refer to Figure 2 The bracket 1 is a support structure located inside the electronic pen, providing a mounting base for other components. In Embodiment 1 of this application, the bracket 1 is specifically the bracket 1 of the pressure-sensitive module of the electronic pen, and is used to fix and mount the spring 4 of the pressure-sensitive module of the electronic pen. The bracket 1 is fixedly installed inside the electronic pen, and the inner cavity 13 of the bracket 1 is used to accommodate the spindle assembly 7 of the electronic pen. The spindle assembly 7 may include the spindle, electrodes, insulating components, and other structures of the electronic pen. The spindle assembly 7 is usually fixedly connected to the tip of the electronic pen. When the electronic pen is writing, the pressure on the tip can be transmitted to the spindle assembly 7 located in the inner cavity 13 of the bracket 1. The spindle assembly 7 is subjected to pressure and moves relative to the bracket 1, thereby forcing the spring 4 mounted on the bracket 1 to deform. By detecting the degree of deformation of the spring 4, the electronic pen can obtain the pressure data on the tip and then make corresponding response actions or adjustments.

[0042] refer to Figure 3 The bracket 1 is specifically a tubular structure formed by winding a single sheet metal piece 1a. In other words, the bracket 1 described in Embodiment 1 of this application is processed by sheet metal stamping. The shape of the sheet metal piece 1a constituting the bracket 1 can be determined according to actual needs. For example, the sheet metal piece 1a can be a rectangular plate, or it can be an irregular shape with a hollowed-out surface or notches on the edges. The shape of the bracket 1 also depends on the actual installation needs. For example, the bracket 1 can be a cylindrical tubular structure, that is, the cross-section of the bracket 1 along the axial direction is a ring; or, the bracket 1 can also be a prismatic tubular structure, that is, the cross-section of the bracket 1 along the axial direction is a polygonal ring.

[0043] refer to Figure 1 The bracket 1 has a first sidewall 11, wherein the first sidewall 11 is a structure formed by splicing two opposite ends of a plate 1a, and the two opposite ends of the plate 1a respectively serve as a first part 11a and a second part 11b of the first sidewall 11. A seam 12 is formed between the first part 11a and the second part 11b, and each of the first part 11a and the second part 11b has at least one first positioning structure 111. The number of such structures can be one, two, three, four, or even more, so that the first sidewall 11 has at least two first positioning structures 111. In other words, the first sidewall 11 is divided into a first part 11a and a second part 11b by the seam 12 formed by splicing the first part 11a and the second part 11b, and both the first part 11a and the second part 11b have at least one first positioning structure 111. In Embodiment 1 of this application, the first sidewall 11 is a straight wall. The bracket 1 also has a second sidewall 14, which is an arc-shaped wall. The straight wall and the curved wall are fixedly connected so that the cross-sectional shape of the bracket 1 along the axial direction is close to the letter D.

[0044] refer to Figure 1The connector 2 is a structure used to position and connect the first part 11a and the second part 11b. Specifically, the connector 2 has at least two second positioning structures 21, and each second positioning structure 21 is connected to a first positioning structure 111. In other words, the connector 2 crosses the seam 12 of the bracket 1 and is connected to the first part 11a and the second part 11b of the first sidewall 11, respectively. In this way, the positions of the first part 11a and the second part 11b can be maintained by the connector 2, which helps to ensure the shape of the bracket 1. In the first embodiment of this application, the first positioning structure 111 and the second positioning structure 21 can be selected according to actual needs. For example, the first positioning structure 111 can be a cylindrical protrusion, and the second positioning structure 21 can be a circular hole. During installation, the first positioning structure 111 is inserted into the second positioning structure 21. Alternatively, the first positioning structure 111 can be a rectangular hole, and the second positioning structure 21 can be a cubic protrusion. During installation, the second positioning structure 21 is inserted into the first positioning structure 111. Alternatively, the first positioning structure 111 can be a snap-fit, and the second positioning structure 21 can be a hole that fits into the snap-fit. During installation, the first positioning structure 111 is snapped into the second positioning structure 21.

[0045] During the assembly and use of the electronic pen, thanks to the retaining effect of the connector 2, the bracket 1 is less prone to cracking at the splicing position, i.e., the aforementioned seam 12. Therefore, the connector 2 helps the bracket 1 stably maintain its tubular structure. At the same time, this eliminates the need for welding to connect the first part 11a and the second part 11b to form the seam 12, thus effectively simplifying the manufacturing process of the bracket 1, reducing its processing cost, and consequently lowering the overall production cost of the electronic pen.

[0046] Example 2:

[0047] Embodiment 2 of this application further improves upon Embodiment 1. Compared to Embodiment 1, the electronic pen provided in Embodiment 2 also has a bracket 1 and a connector 2, and the connection method between the bracket 1 and the connector 2 is the same. Embodiment 2 mainly further defines the specific structure of the bracket 1 and the connector 2.

[0048] refer to Figure 1In the second embodiment of this application, optionally, one of the first part 11a and the second part 11b has a connecting groove 112, and the other of the first part 11a and the second part 11b has a connecting tooth 113, and the outer dimensions of the connecting groove 112 are adapted to the outer dimensions of the connecting tooth 113. When the plate 1a is wound into the bracket 1, the connecting tooth 113 on one of the first part 11a and the second part 11b engages in the connecting groove 112 of the other of the first part 11a and the second part 11b. Through the cooperation of the connecting tooth 113 and the connecting groove 112, the first part 11a and the second part 11b can remain relatively fixed. During the use and installation of the electronic pen, the bracket 1 is not prone to cracking at the splicing position of the first part 11a and the second part 11b, that is, at the joint 12 of the first part 11a and the second part 11b, and can stably maintain its tubular structure.

[0049] In Embodiment 2 of this application, the number of connecting teeth 113 and connecting grooves 112 can be determined according to actual needs. Specifically, in the first part 11a and the second part 11b, one can have m connecting teeth 113, and correspondingly, the other has m connecting teeth 113. The value of m can be one, two, three, or even more. The first part 11a and the second part 11b can both have connecting grooves 112 and connecting teeth 113. In other words, in the first part 11a and the second part 11b, one can have m connecting teeth 113 and n connecting grooves 112, and correspondingly, the other has n connecting teeth 113 and m connecting grooves 112. The values ​​of m and n can be one, two, three, or even more, which will not be listed in detail here.

[0050] refer to Figure 1 In the second embodiment of this application, optionally, the first part 11a has connecting teeth 113 and the second part 11b has connecting grooves 112.

[0051] The connecting tooth 113 is a tooth-like structure protruding from the edge of the first part 11a, having a first end near the second part 11b and a second end away from the second part 11b. For any connecting tooth 113 on the first part 11a, along the axial direction of the support 1, the size of the first end of the connecting tooth 113 is larger than the size of the second end of the connecting tooth 113. That is, the connecting tooth 113 is specifically shaped as wide at the end and narrow at the root.

[0052] The connecting groove 112 is a recessed structure at the edge of the second part 11b, having a first end near the first part 11a and a second end away from the first part 11a. Adapted to the connecting tooth 113, along the axial direction of the bracket 1, the size of the first end of the connecting groove 112 is smaller than the size of the second end of the connecting groove 112. Specifically, the connecting groove 112 has a shape that is narrow at the opening and wide at the bottom.

[0053] Alternatively, the first part 11a has a connecting groove 112 and the second part 11b has a connecting tooth 113.

[0054] At this point, the connecting groove 112 is the recessed structure at the edge of the first part 11a, having a first end near the second part 11b and a second end away from the second part 11b. Adapted to the connecting tooth 113, along the axial direction of the bracket 1, the size of the first end of the connecting groove 112 is smaller than the size of the second end of the connecting groove 112. Specifically, the connecting groove 112 has a shape with a narrow opening and a wide bottom.

[0055] The connecting tooth 113 is a tooth-like structure protruding from the edge of the second part 11b, having a first end near the first part 11a and a second end away from the first part 11a. For any connecting tooth 113 on the second part 11b, along the axial direction of the support 1, the size of the first end of the connecting tooth 113 is larger than the size of the second end of the connecting tooth 113. That is, the connecting tooth 113 is specifically shaped as wide at the end and narrow at the root.

[0056] Of course, both the first part 11a and the second part 11b can be provided with connecting grooves 112 and connecting teeth 113. The shape of the connecting grooves 112 is as described above, which is narrow at the opening and wide at the bottom. The shape of the connecting teeth 113 is as described above, which is wide at the end and narrow at the root. Further details will not be provided here.

[0057] Because the connecting tooth 113 has a wide end and a narrow root, and the connecting groove 112 has a correspondingly narrow opening and a wide bottom, after the connecting tooth 113 is engaged in the connecting groove 112, the end of the connecting tooth 113 can hook onto the opening of the connecting groove 112 to prevent the connecting tooth 113 from coming out of the connecting groove 112. This ensures the reliability of the engagement between the connecting tooth 113 and the connecting groove 112, thereby achieving a reliable connection between the first part 11a and the second part 11b. This effectively prevents the bracket 1 from cracking at the joint 12, and at the same time, the structure is simple, easy to process, and helps to reduce the processing and forming cost of the bracket 1.

[0058] A specific shape of the connecting tooth 113 can be referenced. Figure 1As shown. The connecting tooth 113 includes a tooth tip edge 1131 and two tooth sides 1132, which are spaced apart from each other. The tooth tip edge 1131 is located between the first ends of the two tooth sides 1132, and the second ends of the two tooth sides 1132 are connected to the main body of the first sidewall 11. The distance between the first ends of the two tooth sides 1132 is greater than the distance between the second ends of the two tooth sides 1132. In other words, at the edge of the first sidewall 11, a portion of the edge protrudes outward to form a connecting tooth 113 in the shape of an isosceles trapezoid or a dovetail. The two tooth sides 1132 of the connecting tooth 113 form a wedge-shaped gap with the other edges of the first sidewall 11. Since the connecting tooth 113 and the connecting groove 112 have the same external dimensions, the groove opening of the connecting groove 112 has a wedge-shaped protrusion that can be joined with the wedge-shaped gap. For ease of processing and use, the sharp corners of both the connecting tooth 113 and the connecting groove 112 are rounded. When the connecting tooth 113 engages with the connecting groove 112, the wedge-shaped gap at the connecting tooth 113 can hook with the wedge-shaped protrusion at the connecting groove 112 to ensure that the first part 11a and the second part 11b will not separate, thereby ensuring that the joint 12 of the bracket 1 will not crack.

[0059] Another specific shape of the connecting tooth 113 can be referenced. Figure 4As shown. In Embodiment 2 of this application, optionally, the connecting tooth 113 includes a tooth tip edge 1131, a tooth bottom edge 1133, and two tooth side edges 1132, with the two tooth side edges 1132 arranged at intervals relative to each other. The tooth tip edge 1131 is located between the first ends of the two tooth side edges 1132, and the tooth bottom edge 1133 is located between the second ends of the two tooth side edges 1132, while the length of the tooth tip edge 1131 is greater than the length of the tooth bottom edge 1133. In other words, at the edge of the first sidewall 11, a portion of the edge protrudes outward to form a connecting tooth 113 in the shape of a right-angled trapezoid. One of the tooth side edges 1132 of the connecting tooth 113 forms a wedge-shaped gap with the other edges of the first sidewall 11, and the tooth bottom edge 1133, tooth tip edge 1131, and the other tooth side edge 1132 of the connecting tooth 113 form an overhanging hook-shaped structure. Since the connecting teeth 113 and the connecting groove 112 have the same external dimensions, the groove opening of the connecting groove 112 has a wedge-shaped protrusion that can be spliced ​​with the wedge-shaped gap, and a recess that fits the hook-shaped structure. For ease of processing and use, the sharp corners of both the connecting teeth 113 and the connecting groove 112 are rounded. When the connecting teeth 113 and the connecting groove 112 are engaged, the wedge-shaped gap at the connecting teeth 113 can hook with the wedge-shaped protrusion at the connecting groove 112, and the hook-shaped structure of the connecting teeth 113 can hook with the recess at the connecting groove 112, ensuring that the first part 11a and the second part 11b do not separate, thus preventing the joint 12 of the bracket 1 from cracking. Similarly, this eliminates the need for welding to connect the joint 12 formed by the splicing of the first part 11a and the second part 11b, effectively simplifying the processing technology of the bracket 1, reducing its processing cost, and consequently reducing the overall production cost of the electronic pen.

[0060] The above-mentioned shape can be obtained by sheet metal stamping and other methods, and is easy to form. Therefore, by adopting the above-mentioned shape for the connecting tooth 113 and the connecting groove 112, the connection strength at the joint 12 of the bracket 1 can be improved, while reducing the processing difficulty of the bracket 1, simplifying the processing technology of the bracket 1, and thus reducing the production cost of the electronic pen.

[0061] refer to Figure 2 In the second embodiment of this application, optionally, the electronic pen also includes a fastener 3, which may specifically be a screw, bolt, etc. Correspondingly, the first sidewall 11 has a connecting through hole 114, and the connector 2 has a connecting threaded hole 22. The fastener 3 passes through the connecting through hole 114 and is threadedly connected to the connecting threaded hole 22, thereby achieving a fixed connection between the bracket 1 and the connector 2. This ensures a reliable fixed connection between the connector 2 and the bracket 1, thereby enabling the connector 2 to provide reliable retention to prevent the bracket 1 from cracking at the joint 12.

[0062] refer to Figure 5In the second embodiment of this application, optionally, both the first part 11a and the second part 11b have a notch 114a, which forms a connecting through hole 114. When the fastener 3 is installed into the connecting through hole 114 and the connecting threaded hole 22, since the connecting through hole 114 is formed by the notch 114a of the first part 11a and the second part 11b, the first part 11a and the second part 11b can be pressed and held between the head of the fastener 3 and the connector 2. In this way, the fastener 3 can provide a holding effect for the bracket 1. Under the pressing and holding of the fastener 3, the bracket 1 is not prone to cracking at the joint 12 of the first part 11a and the second part 11b. Therefore, the above-mentioned arrangement is also conducive to the bracket 1 maintaining its own tubular structure stably. In this way, there is no need to connect the joint 12 formed by splicing the first part 11a and the second part 11b by welding, which can effectively simplify the processing technology of the bracket 1, reduce the processing cost of the bracket 1, and help reduce the overall production and processing cost of the electronic pen.

[0063] In the second embodiment of this application, optionally, one of the first positioning structure 111 and the second positioning structure 21 is a first positioning hole, and the other of the first positioning structure 111 and the second positioning structure 21 is a positioning post. Specifically, refer to... Figure 5 The first positioning structure 111 is the first positioning hole, as shown in the reference. Figure 6 The second positioning structure 21 is a positioning post. Of course, the first positioning structure 111 can also be a positioning post, and the second positioning structure 21 can also be a first positioning hole. When installing the connector 2, the positioning post is inserted into the first positioning hole. The connector 2 and the bracket 1 achieve the holding function of the connector 2 on the bracket 1 through the cooperation of the positioning post and the first positioning hole. The positioning post and the first positioning hole have a simple structure, are easy to process and assemble, thus effectively reducing the processing difficulty and assembly difficulty of the connector 2 and the bracket 1, thereby reducing the production cost of the electronic pen.

[0064] Example 3:

[0065] Embodiment 3 of this application is a further improvement on Embodiment 1. Compared with Embodiment 1, the electronic pen provided in Embodiment 3 of this application also has a bracket 1 and a connector 2, and the connection method between the bracket 1 and the connector 2 remains unchanged.

[0066] In the third embodiment of this application, the electronic pen may optionally include a spring 4, a force transmission element 5, and a deformation sensor 6.

[0067] refer to Figure 7The spring 4 includes a connecting portion 41 and a deformable portion 42. Along the first direction X, there are two connecting portions 41 arranged at intervals, and the deformable portion 42 connects the two connecting portions 41. In other words, in Embodiment 3 of this application, the spring 4 is specifically a U-shaped spring 4, wherein the two opposing parts of the U-shaped spring 4 are the connecting portions 41, and the deformable portion 42 connects the two connecting portions 41.

[0068] refer to Figure 8 The force transmission component 5 is the component used for transmission connection with the main spindle assembly 7. The connecting component 2 and the force transmission component 5 are arranged at intervals relative to each other along the first direction X, and are respectively connected to a connecting portion 41 of the spring piece 4. Since the connecting component 2 is connected to the bracket 1, after the force transmission component 5 is subjected to external force, it can drive the spring piece 4 to deform. The deformation sensor 6 can detect the deformation of the spring piece 4. Specifically, the deformation sensor 6 is connected to the deformation portion 42 of the spring piece 4 to obtain the deformation data of the spring piece 4, and thus obtain the force data of the force transmission component 5. In this embodiment, after the pen tip is subjected to external pressure, it can generate movement relative to the bracket 1, and the main spindle assembly 7 moves synchronously under the drive of the pen tip. The main spindle assembly 7 is connected to the force transmission component 5, so that the force transmission component 5 can move relative to the bracket 1, thereby driving the spring piece 4 to deform. The deformation sensor 6 detects the deformation data of the spring piece 4, so that the electronic pen can obtain the force data of the pen tip based on the deformation data of the spring piece 4, thereby realizing the pressure-sensitive detection function of the electronic pen. In the above configuration, connector 2 provides a reliable mounting base for spring 4, which helps ensure that spring 4 deforms according to the preset method. This ensures the accuracy and reliability of the electronic pen's pressure sensitivity detection, while simplifying the structure and assembly process of the pressure sensitivity detection unit on the electronic pen, thus helping to reduce the production and processing costs of the electronic pen.

[0069] refer to Figure 8 In embodiment three of this application, optionally, two spring pieces 4 are provided, and the two spring pieces 4 are arranged at intervals relative to each other along the second direction Y. The second direction Y is a direction that intersects with the first direction X. Specifically, the first direction X and the second direction Y can be in a general intersecting relationship, that is, the angle between the first direction X and the second direction Y is an acute angle or an obtuse angle. Preferably, the first direction X and the second direction Y are orthogonal.

[0070] Both the force transmission component 5 and the connecting component 2 are fixedly connected to the two spring pieces 4. When the force transmission component 5 is subjected to force and moves, its movement trajectory and the deformation mode of the spring pieces 4 are determined by the limiting effect of the two spring pieces 4. This helps ensure that the spring pieces 4 deform in a preset manner, thus ensuring the accuracy and reliability of the electronic pen's pressure sensitivity detection. To avoid the spindle assembly 7, the deformable part 42 of the spring piece 4 closest to the pen tip can have a clearance hole, through which the spindle assembly 7 passes and connects to the force transmission component 5.

[0071] For specific details, please refer to Figure 9 As shown, in this embodiment of the application, there is an angle between the connecting portion 41 and the deformable portion 42 of the spring piece 4. Preferably, the angle between the connecting portion 41 and the deformable portion 42 of the spring piece 4 is 90 degrees. After the pen tip is subjected to external pressure, it can generate movement relative to the support 1, and the spindle assembly 7 moves synchronously under the drive of the pen tip. The spindle assembly 7 is connected to the force transmission member 5, so that the force transmission member 5 can move relative to the support 1. At this time, the spring piece 4 deforms, that is, the deformable portion 42 of the spring piece 4 can deflect outward, and the angle between the connecting portion 41 and the deformable portion 42 increases. Or, that is, the deformable portion 42 of the spring piece 4 can deflect inward, and the angle between the connecting portion 41 and the deformable portion 42 decreases. The deformation sensor 6 detects the deformation data of the spring piece 4, so that the electronic pen can obtain the force data of the pen tip based on the deformation data of the spring piece 4, thereby realizing the pressure-sensitive detection function of the electronic pen.

[0072] refer to Figure 8 In embodiment three of this application, optionally, the connector 2 has a connecting buckle 23, and the connecting part 41 has a connecting hole 43. The spring piece 4 and the connector 2 are fixed to each other by the engaging of the connecting buckle 23 and the connecting hole 43. This ensures a reliable fixed connection between the spring piece 4 and the connector 2, and simplifies the connection structure and assembly method of the spring piece 4 and the connector 2, thus also helping to reduce the production and processing costs of the electronic pen.

[0073] In embodiment three of this application, optionally, reference is made to... Figure 3The connector 2 has a positioning protrusion 24, and the connecting part 41 has a second positioning hole 44. The second positioning hole 44 is connected to the positioning protrusion 24 to achieve positioning and engagement between the spring 4 and the connector 2. This ensures the positioning accuracy of the spring 4 and the connector 2, which is beneficial to ensuring the accuracy of the installation position of the spring 4. Therefore, it is beneficial to ensure that the spring 4 deforms in a preset manner, thereby ensuring the accuracy and reliability of the electronic pen pressure sensitivity detection. In the third embodiment of this application, the positioning protrusion 24 is specifically an annular protrusion surrounding the connecting threaded hole 22 on the connector 2. The positioning protrusion 24 is inserted into the second positioning hole 44 on the connecting part 41 of the spring 4 to ensure the positioning accuracy of the spring 4 relative to the connector 2. To facilitate the assembly of the spring 4, a slope 241 can be provided on one side of the positioning protrusion 24 to guide the installation of the spring 4 and reduce the installation resistance during the installation of the spring 4.

[0074] In Embodiment 3 of this application, the two ends of the connector 2 are recessed, forming a cavity with the inner wall of the bracket 1 to accommodate the connecting portion 41 of the spring piece 4. When the spring piece 4 is fixedly connected to the connector 2, the connecting portion 41 of the spring piece 4 is precisely accommodated within this cavity. (Reference) Figure 3 The connector 2 can be provided with bosses 25 at both ends. The bosses 25 contact the opposite sides of the connecting part 41 of the spring piece 4 to ensure that the connector 2 can still provide support for the spring piece 4 when the spring piece 4 is deformed. During installation, first snap one connecting part 41 of the spring piece 4 onto both ends of the connector 2, and then use screws to fix the other connecting part 41 of the spring piece 4 to the force transmission member 5; then install the assembly composed of the spring piece 4, connector 2 and force transmission member 5 into the bracket 1, and then use screws, bolts and other fasteners 3 to fix the bracket 1 and connector 2.
