In this way, the verification efficiency of the sensor of different types of vehicles is greatly improved.

[0044] Specifically, a clamping notch is arranged on the connecting piece 12, and a flange matched with the clamping notch is arranged on the hanging clamping piece 2202.

[0045] Alternatively, an opening is arranged on the connecting piece 12, and a protruding column matched with the opening is arranged on the hanging clamping piece 2202.

[0046] Please refer to FIG. 18 and FIG. 19. In some embodiments, the bracket assembly 22 further comprises a bracket body 2201 connected with the hanging clamping piece 2202, and the bracket body 2201 is connected with the carrier body 21.

[0047] It can be understood that the bracket body 2201 is a main part of the bracket assembly 22, and is also a part connected with the carrier body 21. Here, the structure of the bracket body 2201 is not limited, for example, the bracket body 2201 can be a frame structure, a plate structure, a rack structure, etc.

[0048] The hanging clamping piece 2202 is connected with the bracket body 2201. Here, the connection form of the hanging clamping piece 2202 and the bracket body 2201 is not limited, for example, the hanging clamping piece 2202 can be fixedly connected with the bracket body 2201, that is, the two are connected by screws, welding, etc.; or, the hanging clamping piece 2202 can also be movably connected with the bracket body 2201, that is, the two can be movably connected through the corresponding connecting piece 12, specifically, the hanging clamping piece 2202 and the bracket body 2201 can be slidably connected through a slide rail and a slide block, or can also be slidably connected through a screw rod mechanism.

[0049] Please refer to FIG. 18 and FIG. 19. In some embodiments, the bracket body 2201 comprises two longitudinal beams 22011 and at least two transverse beams 22012, each transverse beam 22012 is arranged in a vertical direction, and opposite ends of each transverse beam 22012 are connected with corresponding longitudinal beams 22011, the hanging clamping piece 2202 is arranged on the two longitudinal beams 22011, and the two longitudinal beams 22011 are connected with the carrier body 21.

[0050] It can be understood that the bracket body 2201 is mainly formed by the two longitudinal beams 22011 and the at least two transverse beams 22012, for example, if the number of the transverse beams 22012 is two, then the two longitudinal beams 22011 and the two transverse beams 22012 form a frame structure, and the weight of the bracket body 2201 is lighter.

[0051] Of course, in other embodiments, the number of longitudinal beams 22011 can also be increased accordingly, for example, by adding an additional longitudinal beam 22011, and arranging the longitudinal beam 22011 between two transverse beams 22012 for supporting the two transverse beams 22012, thereby improving the structural strength of the support body 2201.

[0052] In addition, the connection form of the two longitudinal beams 22011 and the carrier body 21 includes but is not limited to insertion, clamping, threaded connection, and welding, etc.

[0053] In this way, the support body 2201 is enclosed by the longitudinal beams 22011 and the transverse beams 22012, and has a simple overall structure, is lighter in weight, and is easy to assemble.

[0054] Referring to FIG. 18, in some embodiments, the support assembly 22 includes a locking piece 2203, which is arranged through the longitudinal beam 22011 and connected to the connecting piece 12.

[0055] It can be understood that the structural form of the locking piece 2203 includes but is not limited to a bolt, a screw rod, and a threaded connecting piece 12.

[0056] In use, the locking piece 2203 is rotated to form a connection relationship between the support body 2201 and the connecting piece 12.

[0057] In this way, the display body 11 is locked and fixed by the locking piece 2203, so as to improve the connection stability of the display body 11 on the support assembly 22.

[0058] Referring to FIG. 2, in some embodiments, the carrier body 21 includes:

[0059] The horizontal distance adjusting mechanism 100 includes a base 101, a horizontal guide mechanism 102 arranged on the base 101, and a support structure 103 fixedly connected to the horizontal guide mechanism 102, the support structure 103 sliding along the horizontal direction through the horizontal guide mechanism 102;

[0060] The vertical distance adjusting mechanism 200 includes a support frame 201 fixed to the support structure 103, a power part 202 arranged on the support frame 201, a first lead screw assembly 203 connected to the power part 202, and a rocker 204 rotationally connected to the support frame 201; the first lead screw assembly 203 includes a first lead screw body 205 rotationally connected to the support frame 201 at one end and an output end of the power part 202 at the other end, and a first nut part 206 sleeved on the first lead screw body 205, and the rocker 204 is engagedly connected to the first lead screw body 205;

[0061] The angle adjusting mechanism 300 comprises a fixed assembly 301 fixedly connected to the first nut portion 206, a rotating shaft member 302 rotatably connected to the fixed assembly 301, a mounting assembly 303 connected to the rotating shaft member 302 and capable of rotating around the axis of the rotating shaft member 302, and an adjusting rod 304 arranged on the fixed assembly 301 and capable of pushing against the mounting assembly 303, and the adjusting rod 304 drives the long side or the short side of the mounting assembly 303 to rotate around the axis of the rotating shaft member 302 by pushing.

[0062] The two longitudinal beams 22011 are connected to the mounting assembly 303.

[0063] It can be understood that the horizontal distance adjusting mechanism 100 comprises a base 101, a horizontal guide mechanism 102, and a support structure 103 capable of moving in the horizontal direction under the guidance of the horizontal guide mechanism 102, thereby achieving the adjustment of the distance of the support body 2201 in the horizontal direction; the vertical distance adjusting mechanism 200 comprises a support frame 201, a power portion 202, a first screw rod assembly 203, and a rocker member 204; the first screw rod assembly 203 comprises a first screw rod body 205 and a first nut portion 206. Here, the support frame 201 is mounted on the support structure 103, so that the entire vertical distance adjusting mechanism 200 can move in the horizontal direction, and at the same time, the power portion 202 outputs power to drive the first screw rod body 205 of the first screw rod assembly 203 to rotate around the shaft, and finally, the first nut portion 206 moves in the vertical direction, i.e., the adjustment of the distance of the support body 2201 in the vertical direction is achieved. In addition to the electrically driven lifting of the first nut portion 206, the rotation of the first screw rod body 205 around the shaft can also be achieved by rotating the rocker member 204. The angle adjusting mechanism 300 comprises a fixed assembly 301, a rotating shaft member 302, a mounting assembly 303, and an adjusting rod 304. The mounting assembly 303 can rotate around the axis of the rotating shaft relative to the fixed assembly 301 in the long side direction or the short side direction, so that the two longitudinal beams 22011 arranged on the mounting assembly 303 rotate around the shaft together with the mounting assembly 303, and the entire angle adjusting process is achieved by pushing or pulling the mounting assembly 303 to rotate around the shaft by the adjusting rod 304, so that the rotation angle of the mounting assembly 303 around the shaft is controlled, and the precision of the rotation of the two longitudinal beams 22011 around the shaft is improved. In summary, the calibration device of the present application can adjust the distance of the support body 2201 in the horizontal direction and the vertical direction, and can also adjust the angle of the two longitudinal beams 22011 around the rotating shaft member 302, thereby improving the calibration efficiency of the calibration device, i.e., the display body 11 can be adjusted in space to adapt to the use requirements of different types of vehicles.

[0064] Please refer to FIG. 3 to FIG. 7, in an embodiment, the base 101 comprises two crossbeams 2201 1204 which are parallel and spaced. Here, the two crossbeams 2201 1204 are used to limit the space for the horizontal sliding of the support body 2201, that is, the support body 2201 is horizontally sliding between the two crossbeams 2201 1204. The horizontal guiding mechanism 102 comprises guiding parts 106 provided on the corresponding crossbeams 2201 1204 and sliding block parts 107 connected to the guiding parts 106. It can be understood that the guiding direction of the guiding parts 106 is parallel to the extension direction of the crossbeams 2201 1204, and the sliding block parts 107 slide under the guiding action of the guiding parts 106, so as to regulate the moving direction of the support body 2201 and improve the distance adjusting accuracy. The support structure 103 comprises a support plate body 108 and support arms 109 provided at opposite ends of the support plate body 108, and the support plate body 108 is connected to the sliding block parts 107 through the support arms 109. Among them, the support plate body 108 is used to fix the support frame 201 of the vertical distance adjusting mechanism 200, and the support arms 109 are connected to the sliding block parts 107 and slide together with the sliding block parts 107. Finally, the support frame 201 moves under the guiding action of the guiding parts 106 along with the support plate body 108. In this way, the support frame 201 installed on the support plate body 108 slides on the guiding parts 106 through the sliding block parts 107, so as to change the horizontal displacement of the support frame 201, and the sliding direction of the sliding block parts 107 can be regulated through the limiting of the guiding parts 106, thereby improving the distance adjusting accuracy of the support plate body 108 in the horizontal plane.

[0065] Please refer to FIG. 3 to FIG. 7, in an embodiment, the support arm 109 comprises a first support sub-arm 110 and a second support sub-arm 111. Among them, the cross section of the first support sub-arm 110 is L-shaped, and the first support sub-arm 110 comprises a vertical section 112 and a horizontal section 113 perpendicular to the vertical section 112, the vertical section 112 is connected to the sliding block parts 107, and the support plate body 108 is placed on the horizontal section 113. It can be understood that the mounting end surface of the support plate body 108 is lower than the upper end surface of the crossbeams 2201 1204, that is, the support body 2201 is sunken between the two crossbeams 2201 1204, so as to reduce the probability of shaking of the support frame 201 during horizontal movement due to excessive height.

[0066] The second support sub-arm 111 is connected to the vertical section 112. In this way, the cross section of the support arm 109 forms a Z shape, that is, the first support sub-arm 110 can be connected to the sliding block parts 107, or connected to the sliding block parts 107 through the second support sub-arm 111.

[0067] Please refer to FIG. 3 to FIG. 7, in one embodiment, the horizontal distance adjusting mechanism 100 further comprises a locking member 114, which is arranged in the second support sub-arm 111 and abuts against the guide portion 106. It can be understood that when the horizontal moving distance of the support frame 201 is determined, in order to prevent it from moving, the horizontal distance adjusting mechanism 100 is additionally provided with a locking member 114, which is arranged in the second support sub-arm 111 and abuts against the guide portion 106, and the interaction between the locking member 114 and the guide portion 106 is used to achieve that the support structure 103 is stably kept stationary with the cross beam 2201 2104.

[0068] For example, the locking member 114 can be a screw or the like structure, which is used to abut against the guide portion 106 by screwing, so as to achieve the purpose of keeping stationary with the cross beam 2201 2104. Alternatively, the locking member 114 can also be a positioning column or the like structure, and a plurality of positioning holes are arranged on the guide portion 106, and the positioning column is arranged in the corresponding positioning hole, so as to achieve the requirement of stability.

[0069] Specifically, as shown in FIG. 4, the locking member 114 comprises a locking rod 115 arranged in the second support sub-arm 111 and a knob 116 arranged on the locking rod 115. It can be understood that in the embodiment, the locking rod 115 is provided with external threads, and the inner wall of the corresponding through hole of the second support sub-arm 111 is provided with internal threads matched with the external threads, so that the operator drives the locking rod 115 to rotate around the shaft by screwing the knob 116, so as to achieve the abutting action on the guide portion 106.

[0070] Further, in one embodiment, the guide portion 106 is provided with a positioning structure matched with the locking rod 115. It can be understood that when the friction between the end of the locking rod 115 and the surface of the guide portion 106 is insufficient or difficult to achieve that the support structure 103 is stably kept stationary with the cross beam 2201 2104, the locking rod 115 is inserted into the positioning structure to improve the stability of the connection between the two.

[0071] Specifically, the positioning structure is a plurality of blind holes arranged on the guide portion 106 along the sliding direction. It can be understood that the gap between the blind holes can be adjusted according to the actual situation. For example, the distance between the blind holes can be equally spaced, that is, the distance between the blind holes is linear, and then the position of the support body 2201 is equally spaced. Alternatively, the distance between the blind holes can be unequal, that is, the distance between the blind holes is nonlinear, and then the position of the support body 2201 is non-equally spaced.

[0072] Alternatively, the positioning structure is a groove formed on the guide portion 106 along the sliding direction, and a plurality of blind holes are arranged on the inner wall of the groove, each blind hole being arranged at equal intervals or non-equal intervals in the groove. In this way, when the locking rod 115 slides in the groove, the locking rod 115 is prevented from being deviated, and the locking rod 115 is locked and positioned through the corresponding blind hole.

[0073] Please refer to FIGS. 3-7. In an embodiment, the guide portion 106 includes a mounting plate 117 connected to the cross beam 22012104, a guide block 118 protruding outwardly from the mounting plate 117, and an anti-disengagement structure 119 provided on the guide block 118. The sliding block portion 107 is provided with a first groove structure 121 adapted to the anti-disengagement structure 119. It can be understood that the mounting plate 117 serves as a fixed support. Optionally, the mounting plate 117 can be mounted on the cross beam 22012104 by screws or other fasteners. The guide block 118 is in direct contact with the sliding block portion 107, i.e., the sliding block portion 107 moves along the sliding direction under the guidance of the guide block 118. The anti-disengagement structure 119 is used to prevent the sliding block portion 107 from disengaging along a direction perpendicular to the sliding direction, i.e., to prevent the sliding block portion 107 from disengaging from between the two cross beams 22012104, thereby improving the stability of the sliding block portion 107 sliding on the guide block 118.

[0074] For example, as shown in FIGS. 4 and 5, the anti-disengagement structure 119 is a convex rib with an arc-shaped cross section. The sliding block portion 107 is provided with a first groove structure 121 adapted to the convex rib, i.e., the cross-sectional structure of the first groove structure 121 is adapted to the anti-disengagement structure 119. During installation, the sliding block portion 107 is inserted into the guide block 118 from the sliding direction, so that the anti-disengagement structure 119 is inserted into the first groove structure 121. Of course, the cross-sectional shape of the anti-disengagement structure 119 can be adjusted according to actual use requirements. For example, the cross section of the anti-disengagement structure 119 can be arrow-shaped, rectangular, etc.

[0075] Please refer to FIGS. 3-7. In an embodiment, the guide block 118 has a first guide slope 120, the sliding block portion 107 is provided with a second groove structure 122 communicating with the first groove structure 121, the guide block 118 is accommodated in the second groove structure 122, and the second groove structure 122 has a second guide slope 123 abutting against the first guide slope 120. It can be understood that the second guide slope 123 of the sliding block portion 107 abuts against the first guide slope 120 during sliding, thereby distributing part of the gravity on the guide portion 106, so as to prevent the anti-disengagement structure 119 from bearing excessive gravity.

[0076] For example, the guide block 118 has two first guide inclined surfaces 120 arranged oppositely, and the second groove structure 122 has two second guide inclined surfaces 123 corresponding to the first guide inclined surfaces 120. That is, during the sliding process, the two second guide inclined surfaces 123 of the slider part 107 interact with the two first guide inclined surfaces 120 of the guide block 118.

[0077] Referring to FIG. 3, in an embodiment, the base 101 further comprises two vertical beams 105 for limiting the spacing between the two horizontal beams 220 12104, and opposite ends of each vertical beam 105 are connected to the corresponding horizontal beam 220 12104. Here, the vertical beam 105 plays a role of fixation, so that the base 101 becomes a stable structure.

[0078] Referring to FIG. 3, in an embodiment, the horizontal distance adjusting mechanism 100 comprises support rollers 124 arranged on the horizontal beams 220 12104. Understandably, the base 101 can move on the platform with the aid of the support rollers 124. Optionally, the number of support rollers 124 is four, and one support roller 124 is arranged on each opposite end of each horizontal beam 220 12104.

[0079] Specifically, the support roller 124 comprises a roller body, a support part hinged to the roller body, and a fastening part connected to the support part, and the support part is connected to the horizontal beam 220 12104 through the fastening part. For example, the support part has a clamping groove, and the roller body is hinged to the clamping groove through a rotating shaft, and the support part has a mounting end face, and the fastening part penetrates through the horizontal beam 220 12104 and is connected to the mounting end face of the support part. In addition, the support roller 124 further comprises a locking structure for preventing the roller body from rotating in the clamping groove, which plays a role of limiting. It should be noted that the support roller 124 can also be a commercially available roller.

[0080] Referring to FIGS. 8 to 12, the support frame 201 has a bottom end part 208 and a top end part 209 arranged oppositely to the bottom end part 208. Understandably, the support frame 201 plays a role of support and is in an upright state during use. Specifically, the bottom end part 208 of the support frame 201 is in contact with the support platform, and the top end part 209 is away from the support platform, so that the angle adjusting mechanism 300 can reciprocate between the bottom end part 208 and the top end part 209.

[0081] The power part 202 is arranged at the bottom end part 208. Understandably, the power part 202 realizes power output, for example, the power part 202 can be a motor. Specifically, the motor can be started and stopped through a switch, so that the operator only needs to turn on or off the switch to realize the reciprocation of the angle adjusting mechanism 300 between the bottom end part 208 and the top end part 209.

[0082] The first screw rod assembly 203 comprises a first screw rod body 205 having one end connected to the output end of the power unit 202 and the other end rotatably connected to the top end portion 209, and a first nut portion 206 sleeved on the first screw rod body 205, the first nut portion 206 being used for connecting the angle adjusting mechanism 300. It can be understood that the first screw rod body 205 rotates around the axis under the driving of the power unit 202, while the first nut portion 206 cooperated with the first screw rod body 205 does not rotate around the axis with the first screw rod body 205 due to the limiting of the angle adjusting mechanism 300, but moves along the axial direction of the first screw rod body 205, i.e. the rotational movement of the power unit 202 is converted into the linear movement of the first nut portion 206. Specifically, the first nut portion 206 is a nut structure having internal threads, for example, a threaded passage can be formed on a sliding block, and the threaded passage is engaged with the external threads of the first screw rod body 205. Meanwhile, one end of the first screw rod body 205 can be connected to the output end of the power unit 202 through a shaft coupling.

[0083] The rocker member 204 is rotatably connected to the support frame 201 and engaged with the first screw rod body 205. It can be understood that when the rocker member 204 rotates around the axis, it is engaged with the first screw rod body 205, thereby driving the first screw rod body 205 to rotate around the axis to drive the first nut portion 206 to move on the first screw rod body 205. The rocker member 204 is manually operated by an operator.

[0084] In summary, the vertical distance adjusting mechanism 200 has both manual and automatic modes to realize the movement of the support body 2201 in the vertical direction, and thus the corresponding driving mode can be selected according to different scenes, thereby improving the distance adjusting efficiency.

[0085] Please refer to FIGS. 8 to 12, in one embodiment, the first screw rod assembly 203 comprises two fixing frames 207 both arranged on the support frame 201, one of the fixing frames 207 is close to the top end portion 209, and the other fixing frame 207 is close to the bottom end portion 208, and the opposite ends of the first screw rod body 205 are rotatably connected to the corresponding fixing frames 207. Here, the fixing frames 207 support the first screw rod body 205. Alternatively, bearings are arranged on the fixing frames 207, and the opposite ends of the first screw rod body 205 are connected to the corresponding bearings, so that the first screw rod body 205 rotates around the axis between the two fixing frames 207.

[0086] Please refer to FIG. 8, in one embodiment, the vertical distance adjusting mechanism 200 further comprises two guide rails 210, which are symmetrically arranged on the support frame 201 with the central axis of the first screw body 205 as the center of symmetry, and the extension direction of each guide rail 210 is the same as the extension direction of the first screw body 205. It can be understood that the function of the two guide rails 210 is to limit the moving direction of the angle adjusting mechanism 300, that is, under the driving of the first nut part 206, the support body 2201 slides on the two guide rails 210, and at the same time, the guide rail 210 also limits the rotation of the angle adjusting mechanism 300 around the shaft, so as to ensure that the first nut part 206 always moves in the axial direction of the first screw body 205.

[0087] Please refer to FIG. 8, in one embodiment, the vertical distance adjusting mechanism 200 further comprises an up-limit switch 211 and a down-limit switch 212, which are electrically connected with the power part 202. The up-limit switch 211 is arranged on the support frame 201 and close to the top end part 209, and the down-limit switch 212 is arranged on the support frame 201 and close to the bottom end part 208. It can be understood that the up-limit switch 211 is used to limit the upper limit position of the movement of the angle adjusting mechanism 300, and the down-limit switch 212 is used to limit the lower limit position of the movement of the angle adjusting mechanism 300. Specifically, when the first nut part 206 or the angle adjusting mechanism 300 triggers the up-limit switch 211 or the down-limit switch 212, the power part 202 stops power output, thereby avoiding the first nut part 206 or the angle adjusting mechanism 300 from being out of place.

It can be understood that when the first nut part 206 moves close to the fixed frame 207, the corresponding limit switch is triggered, thereby avoiding the first nut part 206 from colliding with the fixed frame 207.

[0089] Please refer to FIG. 8, in one embodiment, the vertical distance adjusting mechanism 200 further comprises a lifting part 213, which is arranged on the support frame 201. It can be understood that the lifting part 213 is arranged to facilitate the disassembly and assembly of the entire vertical distance adjusting mechanism 200, that is, during the disassembly and assembly process, the operator can use the lifting part 213 as the force application position.

[0090] For example, as shown in FIG. 8, the number of lifting parts 213 is two, and the two lifting parts 213 are symmetrically arranged on the support frame 201 with the central axis of the first screw body 205 as the center of symmetry.

[0092] For example, the first transmission member 214 and the second transmission member 216 change the transmission direction of the force in the process of force transmission. Specifically, the first transmission member 214 rotates around the shaft in the vertical direction with the first screw body 205; and the second transmission member 216 can also be selected to rotate around the shaft in the vertical direction, that is, at this time, the rotating plane of the rotating wheel 215 is perpendicular to the axial direction of the first screw body 205.

It can be understood that the cross section of the fixing housing 305 is a U-shaped groove structure, and the mounting assembly 303 is accommodated in the groove structure space formed by the fixing housing 305, of course, according to actual use needs, the mounting assembly 303 can be accommodated in the groove structure space in a long edge direction, or in a short edge direction. In addition, the opposite ends of the rotating shaft member 302 are respectively rotationally connected to the corresponding fixing horizontal plates 308 through bearings, i.e., the rotating shaft member 302 can rotate around the shaft between the two fixing horizontal plates 308.

[0098] Please refer to FIG. 13 to FIG. 17, in one embodiment, the mounting assembly 303 comprises a mounting housing 308, the mounting housing 308 comprises a mounting vertical plate 309 and two mounting horizontal plates 310 vertically connected to the mounting vertical plate 309, the opposite ends of the rotating shaft 302 are respectively penetrated through the corresponding mounting horizontal plates 310, and the rotating shaft 302 is connected to the mounting vertical plate 309.

Optionally, the mounting horizontal plates 310 extend into the groove structure space of the fixed housing 305, and the mounting horizontal plates 310 are parallel to the fixed horizontal plates 308. At the same time, in order to obtain the rotating space, the through holes for the rotating shaft 302 to penetrate are formed on the mounting horizontal plates 310. And the rotating shaft 302 can be connected to the mounting vertical plate 309 through screws and other fasteners, so as to ensure that the mounting vertical plate 309 rotates with the rotating shaft 302.

[0099] Please refer to FIG. 13 to FIG. 17, specifically, the adjusting rod 304 comprises a rod body 311 penetrated through the fixed vertical plate 306 and abutting against the mounting vertical plate 309, and an adjusting handle 312 provided on the rod body 311. It can be understood that the rod body 311 can abut against the mounting vertical plate 309 in a manner of applying force along its axial direction, so as to make the mounting vertical plate 309 rotate relative to the fixed vertical plate 306, at this time, the rod body 311 can be provided with a scale, and the specific rotation angle of the mounting vertical plate 309 is determined according to the scale value. Alternatively, a threaded hole is formed on the fixed vertical plate 306, and an external thread is provided on the rod body 311 and matched with the threaded hole, that is, the rod body 311 is rotated to abut against the mounting vertical plate 309, and similarly, a scale can also be provided on the rod body 311 to clearly indicate the specific rotation angle of the mounting vertical plate 309.

It can be understood that the adjusting rod 304 pushes the mounting assembly 303 to rotate around the fixed assembly 301 by pushing, but it cannot be pulled back after being pushed out, therefore, a reset rod 313 is added, preferably, the reset rod 313 is symmetrically arranged with the adjusting rod 304 with the central axis of the rotating shaft 302 as the symmetric center, so that the mounting assembly 303 after rotating can be pushed back to the reset position through the reset rod 313. At the same time, the waist-shaped hole 314 opened on the fixed assembly 301 also has the effect of limiting the rotating angle of the mounting assembly 303, when the mounting assembly 303 rotates around the shaft to the limit position, the reset rod 313 is limited by the hole wall of the waist-shaped hole 314, so as to prevent the mounting assembly 303 from continuing to rotate.

[0101] For example, as shown in FIG. 13, the fixed vertical plate 306 of the fixed assembly 301 is opened with a waist-shaped hole 314, and one end of the reset rod 313 is connected to the mounting vertical plate of the mounting assembly 303, so as to correspond to the adjusting rod 304 and be distributed on both sides of the rotating shaft 302.

It can be understood that when the target piece has a support rod that needs to be fixed, it can be inserted into the mounting cylinder 315.

[0103] For example, two mounting cylinders 315 are symmetrically arranged on the mounting vertical plate 309, and the mounting cylinder 315 is enclosed to form a containing space containing the longitudinal beam 22011 with the mounting vertical plate 309 as a side wall, and in order to tighten the support rod, a screw is further arranged on the mounting cylinder 315, the screw is penetrated through the mounting cylinder 315 and placed in the containing space, so that the screw can be tightened by screwing.

[0104] Please refer to FIG. 13 to FIG. 17, in an embodiment, the fixed assembly 301 further comprises a fixed cover 316 and a second screw rod assembly 317. Here, the fixed cover 316 is used to be connected with the support body 2201, so that after being connected with the support body 2201, the fixed cover 316 is kept fixed, so that the whole fixed assembly 301 is fixed and the mounting assembly 303 rotates around the axis of the rotating shaft 302 relative to the fixed assembly 301 under the pushing of the adjusting rod 304.

[0105] The second screw rod assembly 317 is used to adjust the horizontal displacement of the fixed vertical plate 306 relative to the fixed cover 316. The second screw rod assembly 317 includes a second nut part 318 connected to the fixed vertical plate 306 and a second screw rod body 319 rotatably connected to the fixed cover 316. The second screw rod body 319 is arranged through the second nut part 318 and threadedly cooperates with the second nut part 318. It can be understood that the fixed housing 305 and the fixed cover 316 can move relative to each other, i.e., they are not fixedly connected. Specifically, the second nut part 318 in the second screw rod assembly 317 is mounted on the fixed vertical plate 306, and the second screw rod body 319 is rotatably connected to the fixed cover 316. When the second screw rod body 319 rotates around the shaft, the second nut part 318 converts the rotation of the second screw rod body 319 around the shaft into movement along the axial direction of the second screw rod body 319, so that the fixed vertical plate 306 can move along the axial direction of the second screw rod body 319 relative to the fixed cover 316. In this way, the support body 2201 can be fine-adjusted in the horizontal direction while obtaining the rotation angle, thereby obtaining a larger range of viewing angle.

[0106] Specifically, the second screw rod assembly 317 includes a positioning ring 320 fixedly connected to the fixed cover 316, and the second screw rod body 319 is rotatably connected to the positioning ring 320 through a bearing. It can be understood that the positioning ring 320 plays a role of connection and bearing. Specifically, the positioning ring 320 is provided with mounting ears, and the positioning ring 320 is fixed to the fixed cover 316 through screws arranged through the mounting ears. Meanwhile, the second screw rod body 319 arranged through the positioning ring 320 rotates in the positioning ring 320.

At this time, the second screw rod body 319 is arranged through one of the positioning rings 320, the second nut part 318 and the other positioning ring 320 in sequence. In this way, the second screw rod body 319 rotates between the two positioning rings 320, and the second nut part 318 moves along the axial direction of the screw nut when the second screw rod body 319 rotates around the shaft. The above-mentioned arrangement mode of the positioning ring 320 has higher stability.

In one embodiment, the second screw rod assembly 317 includes a knob part 321 connected to one end of the second screw rod body 319, and the knob part 321 extends to the outside of the fixed cover 316. It can be understood that the knob part 321 can increase the force point of the operator on the second screw rod body 319, and it is more convenient to rotate the second screw rod body 319.
