[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Please refer to Figures 1 to 5 For description of an assembly structure of a swing arm 102 type road guiding machine provided by the present invention. The assembly structure of the swing arm 102 type road guiding machine includes: a control box 101, a swing arm 102, a connecting rod and a clamping block 103; a connecting sleeve 104 is provided at the top of the control box 101, an installation through hole 105 is opened in the center of the connecting sleeve 104, and a first inclined section 106 is provided near the lower opening of the installation through hole 105. The first inclined section 106 inclines downward and away from the center of the installation through hole 105; the connecting rod includes an upper connecting portion 107 and a lower connecting portion 108. The upper connecting portion 107 is fixedly connected to the swing arm 102, the lower connecting portion 108 is inserted into the installation through hole 105, and a vertical section 109 corresponding to the first inclined section 106 is provided at the lower end of the lower connecting portion 108; the first inclined section 106 and the vertical section 109 form a wedge-shaped groove, and one end of the clamping block 103 is inserted into the wedge-shaped groove from bottom to top, and the clamping block 103 is fixedly connected to the control box 101 through a fastener 110; the fastener 110 applies a force to the clamping block 103, so that the clamping block 103 abuts against the first inclined section 106 and the vertical section 109 respectively.

[0042] An assembly structure of a rocker-arm type road sign provided in this embodiment, compared with the prior art, has a connecting rod and a clamping block 103 installed between the control box 101 and the rocker arm 102. The connecting rod includes an upper connecting portion 107 and a lower connecting portion 108. The upper connecting portion 107 is fixedly connected to the rocker arm 102. The lower connecting portion 108 is inserted into the installation through-hole 105. The first inclined section 106 on the installation through-hole 105 and the vertical section 109 on the lower connecting portion 108 form a wedge-shaped groove. The clamping block 103 is inserted into the wedge-shaped groove from the bottom. The fastener 110 applies an upward force to the clamping block 103. Using the wedge principle, the vertical force of the fastener 110 on the clamping block 103 is converted into a lateral force of the clamping block 103 on the connecting sleeve 104 and the lower connecting portion 108, thereby providing a clamping force for the connecting rod. This structural design has reliable connection, accurate positioning, and is not easy to loosen.

[0043] The fastener 110 is a bolt, and the bolt applies a vertically upward force to the clamping block 103.

[0044] In some embodiments, please refer to Figure 2 and Figure 5 , the clamping block 103 is a circular ring structure. In this embodiment, the first inclined section 106 is a conical surface. Since the clamping block 103 is a circular ring structure, the entire outer circumference of the lower connecting portion 108 is subjected to the force applied by the clamping block 103, so that the force on the lower connecting portion 108 is more balanced. The clamping block 103 is completely fitted with the first inclined section 106 and the vertical section 109, increasing the force-bearing area between the clamping block 103 and the connecting sleeve 104 and the lower connecting portion 108, thereby further improving the stability of the connection structure between the control box 101 and the rocker arm 102. The outer circumference of the clamping block 103 is provided with a connecting flange, and the connecting flange is located below the connecting sleeve 104. The connecting flange is fixedly connected to the bottom of the connecting sleeve 104 by bolts. The connecting flange is provided with through-holes for installing bolts. The inner hole of the clamping block 103 is a circular hole, and the vertical section 109 of the lower connecting portion 108 is a cylinder. The outer surface of the clamping block 103 above the connecting flange is a conical surface, and the diameter dimension of the conical surface gradually decreases from bottom to top.

[0045] In some embodiments, please refer to Figures 2 to 4, a second inclined section 111 is provided near the upper opening of the mounting through hole 105. The second inclined section 111 inclines away from the center of the mounting through hole 105 from bottom to top. A third inclined section 112 that fits the second inclined section 111 is provided on the lower connecting portion 108. In this embodiment, the second inclined section 111 is a conical surface, and the diameter dimension of the conical surface gradually increases from bottom to top. The outer surface of the third inclined section 112 is also a conical surface, and the inclination angles of the second inclined section 111 and the third inclined section 112 are kept consistent. The second inclined section 111 plays a supporting role for the lower connecting portion 108, and at the same time increases the contact area between the connecting sleeve 104 and the connecting rod, thereby improving the stability of the connecting rod on the connecting sleeve 104. Since the second inclined section 111 is a conical surface, it is convenient for the lower connecting portion 108 to be smoothly inserted into the mounting through hole 105.

[0046] In some embodiments, please refer to Figure 2 and Figure 4 , a mounting groove 113 for accommodating the rocker arm 102 is provided at the top of the upper connecting portion 107, and a set screw 114 for locking the rocker arm 102 is mounted on the upper connecting portion 107. In this embodiment, the lower end of the rocker arm 102 is placed in the mounting groove 113, so the mounting groove 113 plays a positioning role for the rocker arm 102. A threaded hole for mounting the set screw 114 is provided on the outer side wall of the upper connecting portion 107. By tightening the set screw 114, the set screw 114 abuts against the outer side wall of the rocker arm 102, thereby realizing the locking and fixing of the rocker arm 102.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 , a reinforcing rib 115 is provided between the connecting sleeve 104 and the control box 101. In this embodiment, the upper end of the connecting sleeve 104 and the control box 101 are fixed by welding. The lower end of the connecting sleeve 104 extends into the control box 101. The reinforcing rib 115 is located inside the control box 101. One end of the reinforcing rib 115 is connected to the top surface of the inner cavity of the control box 101, and the other end of the reinforcing rib 115 is fixedly connected to the outer side wall of the connecting sleeve 104, thereby improving the connection strength between the connecting sleeve 104 and the control box 101. The number of the reinforcing ribs 115 is multiple and they are arranged in sequence along the vertical direction.

[0048] In some embodiments, please refer to Figures 6 to 8, the control box 101 is equipped with a pickup 201, a millimeter-wave radar 202, a camera 203, a display 204, a fan 205, a time control switch 206 and a power supply 207; the pickup 201, the millimeter-wave radar 202, the camera 203 and the display 204 can realize functions such as detecting the presence of people, voice / human-computer interaction, etc. The fan 205 forms an air circulation inside the control box 101, thereby dissipating heat from the control box 101 and ensuring that the components inside the control box 101 can work normally. A filter cotton is installed at the fan 205, and the filter cotton can effectively prevent foreign matters such as dust from entering the control box 101. The visitor inputs demand information through voice, gesture or by touching the display 204, and the control system processes the information and completes the guiding task by controlling the rotation of the rocker arm 102. The time-space switch can turn on and off at a fixed time, which can not only save energy but also extend the product life. The top of the control box 101 adopts a semi-circular design, which can make the rainwater slide off quickly, reduce the residence time of water droplets on the control box 101, and reduce the risk of the control box 101 being corroded by rainwater and the hidden danger of water seepage inside the box. The bottom of the control box 101 adopts a cavity structure. The two ends of the cavity structure in the length direction are transitioned by semi-circular arcs, and support ribs 116 and tension plates 117 are arranged inside. The bottom of the control box 101 is fixed on the installation position. Since the control box 101 has a large windward area outdoors, the bending torque at the bottom is relatively large. The support ribs 116 and the tension plates 117 can increase the structural strength of the bottom of the control box 101 and reduce the stress concentration effect.

[0049] In some embodiments, please refer to Figure 1 , Figure 13 and Figure 14, the rocker arm 102 includes a sleeve tube 301, an upper limit ring 302, a lower limit ring 303, an outer protective cover 304 and a light box 305; the sleeve tube 301 is fixedly connected to the upper connection part 107, the upper limit ring 302 and the lower limit ring 303 are respectively sleeved on the outside of the sleeve tube 301 and are rotatably connected to the sleeve tube 301, the upper and lower ends of the outer protective cover 304 are respectively fixedly connected to the upper limit ring 302 and the lower limit ring 303, and the light box 305 is fixedly installed on the outer protective cover 304. In this embodiment, the lower end of the sleeve tube 301 is inserted into the installation groove 113, and the sleeve tube 301 is fixedly connected to the connecting rod. The upper limit ring 302 and the lower limit ring 303 are respectively located at the upper and lower ends of the sleeve tube 301, and both the upper limit ring 302 and the lower limit ring 303 are sleeved on the outside of the sleeve tube 301. Both the upper limit ring 302 and the lower limit ring 303 are rotatably connected to the sleeve tube 301 through bearings. The outer protective cover 304 is sleeved on the outside of the sleeve tube 301, and the upper and lower ends of the outer protective cover 304 are respectively fixedly connected to the upper limit ring 302 and the lower limit ring 303. The outer protective cover 304 can rotate relative to the sleeve tube 301. The light box 305 is fixedly installed on the outer side wall of the outer protective cover 304. The light box 305 includes an LED dot matrix board 306 and an arrow lamp 307. One end of the LED dot matrix board 306 in the horizontal direction is fixedly connected to the outer protective cover 304, and the arrow lamp 307 is fixedly installed at the end of the LED dot matrix board 306 away from the outer protective cover 304. Navigation information can be displayed on the LED dot matrix board 306, which has a stronger visual impact, is more eye-catching, can quickly attract people's attention, and thus facilitates passers-by to quickly understand the road conditions. The arrow lamp 307 is triangular, and the arrow lamp 307 is also a projection lamp, which can project the guiding arrow onto the ground, making the navigation more convenient and intuitive. A ceiling lamp 308 is also installed at the top of the rocker arm 102. The ceiling lamp 308 not only plays a role in beautifying decoration but also can provide lighting at night. The outer protective cover 304 is bolted to both the upper limit ring 302 and the lower limit ring 303.

[0050] In some embodiments, please refer to Figure 10 , a first sealing ring 309 is installed between the lower limit ring 303 and the sleeve tube 301, and a second sealing ring 310 is installed between the lower limit ring 303 and the outer protective cover 304. In this embodiment, the first sealing ring 309 is a star-shaped sealing ring, and the second sealing ring 310 is an O-shaped sealing ring. The first sealing ring 309 is used to improve the sealing performance between the lower limit ring 303 and the sleeve tube 301, and the second sealing ring 310 is used to improve the sealing performance between the lower limit ring 303 and the outer protective cover 304. Since the installation structures of the upper limit ring 302 and the lower limit ring 303 are the same, the first sealing ring 309 is also installed between the upper limit ring 302 and the sleeve tube 301, and the second sealing ring 310 is also installed between the upper limit ring 302 and the outer protective cover 304.

[0051] In some embodiments, please refer toFigure 9 , Figure 11 and Figure 12 , one end of the sleeve tube 301 is provided with a small-diameter tube 311, the other end of the sleeve tube 301 is provided with a large-diameter tube 312, and the outer diameter of the small-diameter tube 311 is the same as the inner diameter of the large-diameter tube 312. In this embodiment, the number of sleeve tubes 301 is multiple. When it is necessary to assemble two sleeve tubes 301 together, only need to insert the small-diameter tube 311 of one sleeve tube 301 into the large-diameter tube 312 of the other sleeve tube 301. By increasing or decreasing the number of sleeve tubes 301, the overall height dimension of the rocker arm 102 can be changed. An independent outer protective cover 304 is installed on each sleeve tube 301, and a light box 305 is installed on each outer protective cover 304. The lower limit ring 303 and the upper limit ring 302 on two adjacent sleeve tubes 301 are in plug-in fit, and the lower end of the lower limit ring 303 wraps around the outside of the upper limit ring 302, so a stepped structure is formed between the lower limit ring 303 and the upper limit ring 302, thus achieving a rain-proof effect.

[0052] In some embodiments, please refer to Figure 11 and Figure 12 , an anti-rotation boss 313 is provided on the inner wall of the large-diameter tube 312, and an anti-rotation groove 335 matching the anti-rotation boss 313 is provided on the outer wall of the small-diameter tube 311. In this embodiment, when the small-diameter tube 311 is inserted into the large-diameter tube 312, the anti-rotation boss 313 will be inserted into the anti-rotation groove 335, thereby preventing the two sleeve tubes 301 from rotating relative to each other, and improving the anti-torsion strength and anti-bending strength.

[0053] In some embodiments, please refer to Figure 13 and Figure 14 , the rocker arm 102 further includes: a conductive slip ring 330 and a carbon brush 331. One side of the outer protective cover 304 is provided with an interface 319 adapted to the conductive plug of the light box 305; the conductive slip ring 330 is sleeved and fixed on the sleeve tube 301, and the conductive slip ring 330 is coaxially arranged with the outer protective cover 304; the carbon brush 331 is fixedly installed in the interface 319 and is in sliding fit with the conductive slip ring 330, and the carbon brush 331 is used for electrically connecting with the conductive plug of the light box 305.

[0054] Through the above structural design, when the sleeve tube 301 is fixed and the outer protective cover 304 rotates under the drive of external power, the conductive slip ring 330 rotates synchronously, and the carbon brush 331 maintains sliding fit with the conductive slip ring 330 in the interface 319. In this way, no matter how the outer protective cover 304 rotates, the carbon brush 331 can always maintain good electrical connection with the conductive plug of the light box 305, thereby ensuring the stable transmission of current and providing continuous power and electrical energy support for the light box 305.

[0055] The outer protective cover 304 is rotatably mounted on the sleeve tube 301. A conductive slip ring 330 is sleeved and fixed on the sleeve tube 301. An interface 319 is provided on one side of the outer protective cover 304. A carbon brush 331 is fixedly installed inside the interface 319. The carbon brush 331 is in sliding fit with the conductive slip ring 330. After the conductive plug of the light box 305 is inserted into the interface 319, the conductive plug will be electrically connected to the carbon brush 331, thereby realizing the electrical conduction of the circuit of the light box 305. Since the electrical connection mode of the conductive slip ring 330 and the carbon brush 331 is adopted between the outer protective cover 304 and the sleeve tube 301, the outer protective cover 304 can drive the light box 305 to rotate 360°, without being affected by the wires.

[0056] In some embodiments, please refer to Figure 16 , a support seat 320 is detachably installed inside the interface 319, and the carbon brush 331 is fixedly installed on the support seat 320. In this embodiment, the support seat 320 is made of an insulating material, and the support seat 320 is fixed to the inner wall of the interface 319 by bolts. Since the carbon brush 331 is fixedly installed on the support seat 320, it is convenient to disassemble and assemble the carbon brush 331.

[0057] At the same time, the support seat 320 made of an insulating material can effectively avoid the influence on other components such as the internal circuit of the interface 319 due to the conduction of the support seat 320, and ensure the operation safety of the entire system. Moreover, the fixing method by bolts not only ensures the stability of the installation of the support seat 320, but also enables the operation of the support seat 320 and the carbon brush 331 to be conveniently realized by disassembling the bolts when the carbon brush 331 needs to be repaired or replaced, greatly improving the efficiency and convenience of maintenance, and providing a reliable guarantee for the stable operation of the equipment.

[0058] In some embodiments, please refer to Figure 16 and Figure 18, a pressing plate 321 is installed on the support base 320, a conductive sheet 322 is installed on the pressing plate 321, the inner side of the conductive sheet 322 is in contact with the carbon brush 331, and the outer side of the conductive sheet 322 is used to contact the conductive part of the conductive socket of the light box 305. In this embodiment, the pressing plate 321 is fixed on the support base 320 by screws 323, the conductive sheet 322 is fixedly installed on the pressing plate 321, a through hole for installing the conductive sheet 322 is opened in the center of the pressing plate 321, and slots 324 for plugging and matching with the conductive sheet 322 are opened on the opposite two side walls of the through hole. Since the conductive sheet 322 is a copper-based conductive sheet 322, it has a certain elasticity. During the assembly process of the conductive sheet 322, the conductive sheet 322 is first bent and deformed to a certain extent, so as to facilitate inserting both ends of the conductive sheet 322 into the slots 324. The inner surface of the conductive sheet 322 is in contact with the carbon brush 331, and the outer surface of the conductive sheet 322 is in contact with the conductive part of the conductive socket of the light box 305, thereby realizing the electrical connection of the light box 305. A flexible support sleeve 325 is sleeved on the screw 323, and the flexible support sleeve 325 is located between the pressing plate 321 and the support base 320. By adjusting the tightness of the screw 323, the acting force between the conductive sheet 322 and the carbon brush 331 can be changed.

[0059] When it is necessary to adjust the electrical connection state of the light box 305, the tightness of the screw 323 can be adjusted by rotating the screw 323. As the screw 323 is tightened, the flexible support sleeve 325 will be subjected to a certain pressure, and then a upward supporting force will be generated on the pressing plate 321, making the pressing plate 321 tightly press on the conductive sheet 322, thereby increasing the acting force between the conductive sheet 322 and the carbon brush 331 and ensuring the stability of the electrical connection. On the contrary, when the screw 323 is loosened, the supporting force of the flexible support sleeve 325 decreases, the pressure of the pressing plate 321 on the conductive sheet 322 also decreases, and the acting force between the conductive sheet 322 and the carbon brush 331 becomes smaller, so as to realize the fine adjustment of the electrical connection state. Such a design can not only ensure the normal electrical connection of the circuit, but also facilitate flexible adjustment according to actual needs, improving the reliability and adaptability of the whole system.

[0060] In some embodiments, please refer to Figure 16 and Figure 17 , a jack 326 adapted to the carbon brush 331 is opened on the support base 320. In this embodiment, the carbon brush 331 is a rectangular part, the jack 326 is a rectangular through hole, and the jack 326 is adapted to the outer contour of the carbon brush 331. The carbon brush 331 and the jack 326 are in clearance fit. The jack 326 plays a positioning role for the carbon brush 331 and can prevent the carbon brush 331 from shaking.

[0061] In some embodiments, please refer to Figure 16 and Figure 17The carbon brush 331 is slidably matched with the jack 326, and a compression spring 336 is installed between the carbon brush 331 and the conductive sheet 322. In this embodiment, the carbon brush 331 will be worn during operation. Since the compression spring 336 applies a force to the carbon brush 331 toward the side of the conductive slip ring 330, the carbon brush 331 can maintain good contact with the conductive slip ring 330. The length of the wire connecting the carbon brush 331 and the conductive sheet 322 is greater than the length of the compression spring 336, so when the carbon brush 331 is displaced, the wire will not break.

[0062] In some embodiments, see Figure 13 , Figure 14 and Figure 15 , a receiving chamber 314 is provided inside the sleeve tube 301, a driving motor 315 is fixedly installed inside the receiving chamber 314, a reducer 334 is installed on the output shaft of the driving motor 315, the output shaft of the reducer 334 extends upward to the outside of the receiving chamber 314, a driving gear 316 is fixedly installed on the output shaft of the reducer 334, a transmission gear 317 meshing with the driving gear 316 is installed on the top of the sleeve tube 301, and a gear ring 329 meshing with the transmission gear 317 is installed on the outer shield 304. In this embodiment, the sleeve tube 301 is cylindrical, and the receiving chamber 314 penetrates the sleeve tube 301 from top to bottom. The driving motor 315 is installed in the receiving chamber 314, and the output shaft of the driving motor 315 and the output shaft of the reducer 334 are both coaxially arranged with the sleeve tube 301. The driving gear 316 is mounted on the output shaft of the speed reducer 334, the transmission gear 317 is mounted on the top of the sleeve tube 301, and the ring gear 329 is mounted on the outer shield 304. The transmission gear 317 is meshed with the driving gear 316 and the ring gear 329 respectively, so the outer shield 304 can be driven to rotate by the driving motor 315, thereby facilitating the adjustment of the position of the light box 305 on the outer shield 304. A clearance space for avoiding the transmission gear 317 is provided on the sleeve tube 301.

[0063] In actual application, when the position of the light box 305 on the outer shield 304 needs to be adjusted, the drive motor 315 is started, the output shaft of the drive motor 315 starts to rotate, and the drive gear 316 rotates accordingly. The transmission gear 317 is meshed with the drive gear 316, so the transmission gear 317 also starts to rotate. Because the ring gear 329 is installed on the outer shield 304 and meshes with the transmission gear 317, the rotation of the transmission gear 317 drives the ring gear 329 to rotate, and then the outer shield 304 starts to rotate. In this way, the rotation angle and speed of the outer shield 304 can be accurately controlled, so as to realize the convenient adjustment of the position of the light box 305 on the outer shield 304.

[0064] In some embodiments, see Figure 13 and Figure 14, at the top of the outer cover 304 at the topmost part of the rocker arm 102, a top cover 327 is installed. In this embodiment, the top of the outer cover 304 is an open structure, and the ring gear 329, the transmission gear 317, and the drive gear 316 are all installed inside this open structure. The top cover 327 is used to seal the top opening of the outer cover 304, thereby protecting the ring gear 329, the transmission gear 317, and the drive gear 316 and preventing the above-mentioned components from being exposed. The ceiling lamp 308 is fixedly installed on the top cover 327.

[0065] The connection between the top cover 327 and the top opening of the outer cover 304 is relatively tight. Through fixing means such as bolts or welding, it is ensured that it will not loosen or fall off due to factors such as vibration during the operation of the equipment. At the same time, some sealing elements, such as rubber sealing rings, may also be provided on the top cover 327, further enhancing the protection performance of the internal components, preventing dust, impurities, etc. from entering the working areas of the ring gear 329, the transmission gear 317, and the drive gear 316, thereby ensuring the normal operation and service life of these components. In some special environments, such as high-temperature, humid, or dusty places, the protective function of the top cover 327 is particularly important. It can effectively isolate the adverse effects of the external environment on the internal components and provide a reliable guarantee for the stable operation of the equipment.

[0066] In some embodiments, please refer to Figure 13 and Figure 14 , an annular cavity 328 for avoiding the conductive slip ring 330 is provided on the inner circumferential surface of the outer cover 304, and a lower limit ring 303 is installed at the lower opening of the annular cavity 328. In this embodiment, the annular cavity 328 is provided on the inner wall of the outer cover 304. The conductive slip ring 330 is located inside the annular cavity 328. One end of the carbon brush 331 extends into the annular cavity 328. The lower end of the annular cavity 328 is an open structure, and the conductive slip ring 330 can be disassembled and assembled from the bottom of the outer cover 304. The lower limit ring 303 is fixed to the bottom of the annular cavity 328 through the fastener 110, thereby sealing the lower opening of the annular cavity 328 and preventing foreign objects from entering the annular cavity 328, playing a protective role for the conductive slip ring 330 and the carbon brush 331.

[0067] In practical applications, this structural design has many advantages. When the outer shield 304 rotates at high speed, due to the sealing effect of the lower limit ring 303, it can effectively prevent foreign matters such as dust and water vapor from entering the annular cavity 328 along the inner circumferential surface of the outer shield 304, greatly reducing the probability of failures of the conductive slip ring 330 and the carbon brush 331 due to the influence of foreign matters. Moreover, by fixing the lower limit ring 303 to the bottom of the annular cavity 328 through the fastener 110, it not only ensures the reliability of the seal but also facilitates the quick and convenient disassembly of the lower limit ring 303 for corresponding operations when the conductive slip ring 330 needs to be maintained or replaced. At the same time, the annular cavity 328 is opened on the inner wall of the outer shield 304, making reasonable use of the space, making the structure of the entire outer shield 304 more compact and not affecting other functions and performances of the outer shield 304. This design concept has been widely applied in many high-precision and high-reliability rotating devices, providing a solid guarantee for the stable operation of the devices.

[0068] In some embodiments, referring to Figure 13 and Figure 14 , a wire passing hole 318 is provided on the side wall of the sleeve tube 301. The wire passing hole 318 is used to communicate the accommodation cavity 314 and the annular cavity 328. In this embodiment, the conductive slip ring 330 is electrically connected to the power supply device through a wire. The wire can enter the accommodation cavity 314 through the wire passing hole 318 and then be connected to the power supply device located below the sleeve tube 301. Since the wire is completely located inside the sleeve tube 301 and the outer shield 304, the aesthetics are improved, and at the same time, the wire can be prevented from being damaged. A wire harness protection tube 332 is installed on the top of the sleeve tube 301, and the wire passes through the inside of the wire harness protection tube 332, thereby preventing the wire from being squeezed and damaged during the rotation of the gear. A limit switch 333 (position sensor) is installed on the outer side wall of the sleeve tube 301 to achieve the zeroing operation of the device when the device is powered off and then powered on.

[0069] The present invention also provides a road guiding machine, which includes the swing arm 102 type road guiding machine assembly structure of any one of the above. Compared with the prior art, in the swing arm 102 type road guiding machine assembly structure adopted by the road guiding machine of the present invention, a connecting rod and a clamping block 103 are installed between the control box 101 and the swing arm 102. The connecting rod includes an upper connecting portion 107 and a lower connecting portion 108. The upper connecting portion 107 is fixedly connected to the swing arm 102. The lower connecting portion 108 is inserted into the installation through hole 105. The first inclined section 106 on the installation through hole 105 and the vertical section 109 on the lower connecting portion 108 form a wedge-shaped groove. The clamping block 103 is inserted into the wedge-shaped groove from the bottom. The fastener 110 applies an upward force to the clamping block 103. By using the wedge principle, the vertical force of the fastener 110 on the clamping block 103 is converted into a lateral force of the clamping block 103 on the connecting sleeve 104 and the lower connecting portion 108, so as to provide a clamping force for the connecting rod. This structural design has reliable connection, accurate positioning and is not easy to loosen.

[0070] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
