The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0052] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and examples.

[0053] Please refer to Figure 1 The vehicle measuring device 100 provided by the embodiments of the present application includes a base 1, a stand 3, and a cross beam 7. As shown in Figure 2 The base 1 includes a base body 11, which is used to be arranged on a fixed surface such as the ground, as a support for the entire vehicle measuring device 100; as shown in Figures 4 to 6 The stand 3 includes a stand body 31 connected to the base body 11 and a second adjusting assembly 33 arranged on the stand body 31, and the second adjusting assembly 33 is used to connect the cross beam 7 and drive the cross beam 7 to rotate around a second axis Q and a third axis M, please refer to Figure 7 The second axis Q is parallel to the first direction X, and the third axis M is perpendicular to the first direction X.

[0054] Please refer to Figures 6 to 8 In one embodiment, the second adjusting assembly 33 includes a fixed plate 331, a movable plate 332, a first fine adjustment module 333, and a second fine adjustment module 335; the fixed plate 331 is fixedly connected with the drive chain 92 of the lifting drive assembly 9 through a support 313, and the movable plate 332 is rotationally connected to the fixed plate 331 around the second axis Q; the first fine adjustment module 333 is connected between the fixed plate 331 and the movable plate 332, and is used to drive the movable plate 332 to rotate around the second axis Q; the second fine adjustment module 335 is arranged on the movable plate 332 and is used to be fixedly connected with the cross beam 7, and the second fine adjustment module 335 is used to drive the cross beam 7 to rotate around the third axis M.

[0055] In the present embodiment, in order to facilitate understanding and description, a first direction X, a second direction Y, and a third direction Z are defined, which are arranged perpendicular to each other in pairs, and their specific corresponding directions are not limited. For example Figure 1 andFigure 2 As shown, based on actual application, the second direction Y is defined as being directed by the column 3 to the vehicle, with the driving seat as a reference, the second direction Y is the front-rear direction, the first direction X is the left-right direction, and the third direction Z is the vertical direction.

[0056] The rotation of the cross beam 7 around the second axis Q is manifested as the whole cross beam 7 pitching forward and backward, and the rotation of the cross beam 7 around the third axis M is manifested as the left and right sides of the cross beam 7 swinging up and down.

[0057] In the embodiment of the present application, the second adjusting assembly 33 is used to drive the cross beam 7 to rotate around the second axis Q and the third axis M, and the second fine adjustment module 335 is fixedly connected with the midpoint of the cross beam 7 along the first direction X. In this way, the cross beam 7 will not move along the first direction X relative to the second fine adjustment module 335, and the left and right sides of the cross beam 7 can always remain symmetrical in the pitching adjustment process and the swinging adjustment process. The cross beam 7 does not need to make translational motion in the first direction X and the second direction Y on the second adjusting assembly 33, and thus will not affect the rotation of the cross beam 7, and in turn, will not affect the actions of the first fine adjustment module 333 and the second fine adjustment module 335 in the second adjusting assembly 33.

[0058] By contrast, it is assumed that the second adjusting assembly 33 can also drive the cross beam 7 to translate in the first direction X. If the midpoint of the cross beam 7 in the first direction X is not aligned with the second adjusting assembly 33, then when the cross beam 7 is pitching forward and backward, the image acquisition modules 72 at both ends of the cross beam body 71 are different distances from the vehicle to be detected, and the images obtained will be different, affecting the detection result. Therefore, the pitching adjustment can only be performed after the cross beam 7 is adjusted in place along the first direction X.

[0059] Similarly, it is assumed that the second adjusting assembly 33 can also drive the cross beam 7 to translate in the first direction X. If the midpoint of the cross beam 7 in the first direction X is not aligned with the second adjusting assembly 33, then when the cross beam 7 is swinging up and down, the image acquisition modules 72 at both ends of the cross beam body 71 are different distances from the vehicle to be detected, affecting the detection result.

[0060] In the embodiment of the present application, the second fine adjustment module 335 is arranged on the movable plate 332 and fixedly connected with the midpoint of the cross beam 7 along the first direction X, which can improve the adjustment efficiency in the pitching adjustment and the swinging adjustment of the cross beam 7. In the process of the cross beam 7 rotating around the second axis Q and the third axis M, the left and right sides of the cross beam 7 always remain symmetrical.

[0061] In one embodiment, the vehicle measurement device 100 further comprises a lifting driving assembly 9, as shown in Figure 4 and Figure 5As shown, the lifting driving assembly 9 is arranged on the column body 31 and connected with the second adjusting assembly 33, for driving the second adjusting assembly 33 to translate along the third direction Z.

[0062] In one embodiment, referring to Figure 2 and Figure 3 As shown, the base 1 further comprises a first adjusting assembly 12 arranged on the base body 11, the first adjusting assembly 12 is used for driving the column body 31 to rotate around a first axis P (please refer to Figure 3 As shown), the first axis P is parallel to the third direction Z.

[0063] In this way, through the cooperation of the first adjusting assembly 12, the lifting driving assembly 9 and the second adjusting assembly 33, the cross beam 7 can realize translation along the third direction Z, rotation around the first axis P, rotation around the second axis Q and rotation around the third axis M, realizing the adjustment of the position of the cross beam 7 in multiple dimensions, so as to adjust the cross beam 7 to the required position and attitude, meeting the needs of vehicle measurement.

[0064] In the embodiments of the present application, among the multiple groups of adjusting structures for adjusting the position and attitude of the cross beam 7, it is assumed that the adjustment in one dimension corresponds to one group of adjusting structures, in the embodiments of the present application, the first adjusting assembly 12 (corresponding to at least one group of adjusting structures) is arranged on the base body 11, the lifting driving assembly 9 (corresponding to at least one group of adjusting structures) is arranged on the column 3, and the second adjusting assembly 33 (corresponding to at least two groups of adjusting structures) is arranged on the lifting driving assembly 9, so that the multiple groups of adjusting structures are dispersedly arranged, the structures of the first adjusting assembly 12, the lifting driving assembly 9 and the second adjusting assembly 33 can be simplified respectively, and at the same time, the structural correlation between the adjusting structures is reduced, and then the correlation between the adjustment results is reduced, avoiding the problem that repeated and multiple adjustments are required due to the correlation between the adjusting structures, and being beneficial to improving the adjustment efficiency.

[0065] In addition, the dispersed arrangement of the first adjusting assembly 12, the lifting driving assembly 9 and the second adjusting assembly 33 can reduce the assembly and maintenance difficulty of the first adjusting assembly 12, the lifting driving assembly 9 and the second adjusting assembly 33.

[0066] As shown in Figure 1 and Figure 2 In the vehicle measurement device 100, the cross beam 7 further comprises multiple image acquisition modules 72 and a calibration piece 73, the image acquisition modules 72 are respectively arranged at the opposite ends of the cross beam body 71 along the first direction X, and the calibration piece 73 is arranged on the cross beam body 71. In the measurement process of the vehicle, the image acquisition modules 72 are used for acquiring image information of components (such as four wheels) of the vehicle, and the calibration piece 73 is used as a reference point for the sensing system of the vehicle to detect, so as to feedback whether the sensing system of the vehicle is accurate.

[0067] In one embodiment, the first adjusting assembly 12 is further configured to drive the column body 31 to move along a first direction X and a second direction Y. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0068] In one embodiment, at each end of the beam body 71 along the first direction X, the image acquisition module 72 comprises two cameras. The two cameras of one image acquisition module 72 correspond to two wheels on one side of the vehicle to be inspected, respectively. For example, the two cameras located at the left end of the beam 7 are configured to acquire image information of the front left wheel and the rear left wheel.

[0069] One or more calibration members 73 can be arranged on the beam body 71. The plurality of calibration members 73 are arranged on the beam body 71 along the first direction X, as shown in Figure 1 Further, at least one calibration member 73 can be slidable on the beam body 71 along the first direction X to meet the measurement requirements of different parts of the vehicle to be inspected.

[0070] Please refer to Figure 2 and Figure 3 In one embodiment, the first adjusting assembly 12 comprises a first translation member 121, a second translation member 123 and a first rotation member 125. The first translation member 121 is arranged on the base body 11, the second translation member 123 is arranged on the first translation member 121, and the first rotation member 125 is arranged on the second translation member 123. The first translation member 121 is configured to drive the second translation member 123 and the first rotation member 125 to reciprocate along the left-right direction. The second translation member 123 is configured to drive the first rotation member 125 to move along the front-back direction. The first rotation member 125 is configured to drive the column 3 to rotate around the first axis P.

[0071] Specifically, please refer to Figure 3As shown, the first translation member 121 comprises a first screw rod 1212 and a first nut 1213 engaged with each other, and a first support plate 1214 fixedly connected with the first nut 1213; the second translation member 123 comprises a second screw rod 1232 and a second nut 1233 engaged with each other, and a second support plate 1234 fixedly connected with the second nut 1233; the first rotating member 125 comprises a first worm 1252 and a first worm wheel 1253 engaged with each other. The first screw rod 1212 has a central axis parallel to the first direction X, and is rotatably mounted on the base body 11 about the central axis thereof; the first nut 1213 is slidably mounted on the base body 11 along the first direction X. The second screw rod 1232 has a central axis parallel to the second direction Y, and is rotatably mounted on the first support plate 1214 about the central axis thereof; the second nut 1233 is slidably mounted on the first support plate 1214 along the second direction Y. The lower end of the column body 31 is coaxially connected with the first worm wheel 1253, and the first worm wheel 1253 is rotatably mounted on the second support plate 1234 about the first axis P; the first worm 1252 has a central axis perpendicular to the first axis P, and is rotatably mounted on the second support plate 1234 about the central axis thereof.

[0072] Rotation of the first screw rod 1212 can be converted into translation of the first nut 1213 along the first direction X, so as to drive the first support plate 1214 to reciprocally move along the first direction X; rotation of the second screw rod 1232 can be converted into translation of the second nut 1233 along the second direction Y, so as to drive the second support plate 1234 to reciprocally move along the second direction Y; rotation of the first worm 1252 can be converted into rotation of the first worm wheel 1253 perpendicular to the first worm 1252, so as to drive the column 3 to rotate about the first axis P.

[0073] Please continue to refer to Figure 3 As shown, in one embodiment, the first translation member 121 further comprises a first driving member 1211, the second translation member 123 further comprises a second driving member 1231, and the first rotating member 125 further comprises a third driving member 1251.

[0074] The rotation of the first screw rod 1212, the second screw rod 1232 and the first worm 1252 is controlled by the first driving member 1211, the second driving member 1231 and the third driving member 1251, without manual adjustment, so that the labor intensity can be saved; meanwhile, since the height of the base 1 is usually small, the positions of the first screw rod 1212, the second screw rod 1232 and the first worm 1252 are low, and the rotation of the first screw rod 1212, the second screw rod 1232 and the first worm 1252 is controlled by the first driving member 1211, the second driving member 1231 and the third driving member 1251, so that the inconvenience caused by the repeated bending of the operator can be avoided.

[0075] The first driving member 1211, the second driving member 1231 and the third driving member 1251 can be motors respectively.

[0076] In one embodiment, as shown in Figure 1 The vehicle measurement device 100 can include a master control module 83, which is fixedly arranged on the column body 31 and kept at a certain height, which can be a fixed height, for the operator to operate. The master control module 83 is connected with the first driving member 1211, the second driving member 1231 and the third driving member 1251, and the operator can operate the first driving member 1211, the second driving member 1231 and the third driving member 1251 through the master control module 83.

[0077] In addition, the master control module 83 can be connected with the lifting driving assembly 9 to control the start and stop of the lifting driving assembly 9. Specifically, the master control module 83 is connected with the jacking member 91 of the lifting driving assembly 9 and controls the lifting of the push rod of the jacking member 91.

[0078] Further, in one embodiment, the vehicle measurement device 100 can further include a control terminal (not shown), which is connected with the master control module 83 through wired communication or wireless communication. The operator can remotely control the master control module 83 on the control terminal, and then control the first translation member 121, the second translation member 123 and the first rotation member 125.

[0079] Please refer to Figure 3As shown, the first translation member 121 further comprises one or more first guide rails 1215 arranged along the first direction X and a first sliding block (not shown), the first guide rails 1215 are arranged on the base body 11, for example, on the surface of the lower shell 112 of the base body 11, the first sliding block is slidingly arranged on the first guide rails 1215, and the first support plate 1214 is further fixedly arranged on the first sliding block. The second translation member 123 further comprises a plurality of second guide rails 1235 arranged along the second direction Y and a second sliding block (not shown), the second guide rails 1235 are fixedly arranged on the first support plate 1214, the second sliding block is slidingly arranged on the second guide rails 1235, and the second support plate 1234 is further fixedly arranged on the second sliding block.

[0080] As shown in Figure 2 , the base body 11, between the lower shell 112 and the upper shell 111, defines a substantially closed accommodation space, and the first translation member 121, the second translation member 123 and the first rotation member 125 are arranged in the accommodation space. Among them, the first adjusting assembly 12 can further comprise a connecting member (not shown), which is fixedly connected between the first worm gear 1253 and the column body 31, and passes through the upper shell 111. A rotary bearing (not shown) can be arranged between the outer periphery of the connecting member and the upper shell 111 to support the rotation of the connecting member and reduce the friction between the connecting member and the base body 11.

[0081] The base body 11 needs to maintain the stability of the entire vehicle measuring device 100 in the vertical direction, so it needs to have a certain area and weight. In the embodiment of the application, the first adjusting assembly 12 is arranged in the accommodation space of the base body 11, which makes full use of the area and volume of the base body 11, and the first adjusting assembly 12 does not need to occupy space outside the base body 11; it also provides the weight of the base 1 as a whole, and the center of gravity of the base 1 as a whole can be kept at a lower position.

[0082] In addition, the first adjusting assembly 12 does not need to follow the column body 31 to rise and fall, which further reduces the energy consumption of the entire vehicle measuring device 100.

[0083] Next, please refer to Figure 4 and Figure 5 As shown, the column body 31 comprises a fixed column 311 and a lifting column 312, the lower end of the fixed column 311 is fixedly connected to the connecting member of the first adjusting assembly 12 and remains fixed in the third direction Z, and the lifting column 312 is slidingly connected to the fixed column 311 along the third direction Z; the lifting driving assembly 9 is arranged on the fixed column 311 and is used to drive the lifting of the lifting column 312. The second adjusting assembly 33 is arranged on the lifting column 312 to rise and fall with the lifting column 312, thereby realizing the lifting adjustment of the cross beam 7.

[0084] In the embodiments of the present application, the lifting of the column body 31 is achieved by the relative sliding of the lifting column 312 and the fixed column 311. On the one hand, the column body 31 has a variable height, and when the vehicle measurement device 100 is transported, for example, the lifting column 312 can be lowered to the lowest point to facilitate storage and transportation.

[0085] Specifically, as shown in Figure 4 and Figure 5 In one embodiment, the lifting driving assembly 9 includes a jacking member 91 and a driving chain 92. The jacking member 91 is fixedly connected to the fixed column 311 and has a push rod that can be lifted away from the base 1 in the third direction Z. One end of the driving chain 92 is connected to the fixed column 311, and the driving chain 92 slides around the top end of the jacking member 91 (for example, the top end of the jacking member 91 is provided with a pulley). The other end of the driving chain 92 is fixedly connected to the second adjusting assembly 33.

[0086] In this way, when the push rod of the jacking member 91 is lifted by a distance, the parts of the driving chain 92 located on both sides of the jacking member 91 are lifted by the same distance, and the second adjusting assembly 33 moves by twice the distance. The purpose of this arrangement is to achieve a large distance movement of the second adjusting assembly 33 through a small movement of the jacking member 91, which is conducive to further reducing the height of the fixed column 311 in the third direction Z, and in turn, is conducive to reducing the overall height and volume of the vehicle measurement device 100, etc.

[0087] The form of the driving chain 92 is not limited and can be a chain, a steel wire rope, or a rope made of other materials, as long as it can bear the pulling force that causes the second adjusting assembly 33 to rise.

[0088] The end of the driving chain 92 connected to the fixed column 311 is located at the rear side of the fixed column 311, and the other end of the driving chain 92 is located at the front side of the fixed column 311. The second adjusting assembly 33 is located at the front side of the fixed column 311.

[0089] As shown in Figure 5 The column 3 further includes a bracket 313 and a guide roller 314. The bracket 313 is arranged at the front side of the fixed column 311 and is fixedly connected to the rear side of the second adjusting assembly 33 and the other end of the driving chain 92. The bracket 313 is connected to the guide roller 314, and the lifting column 312 is provided with a guide groove 3120 that is opened in the third direction Z. The guide roller 314 is arranged in the guide groove 3120. In this way, the other end of the driving chain 92 drives the bracket 313 and the second adjusting assembly 33 to rise together, and the cooperation of the guide roller 314 and the guide groove 3120 guides the movement of the bracket 313 in the third direction Z.

[0090] Further, by setting the shape of the guide roller 314, such as an I-shaped, and passing through the lifting column 312, the relative position between the bracket 313 and the lifting column 312 can be limited, avoiding the guide roller 314 from escaping from the guide groove 3120.

[0091] In an optional embodiment, as shown in Figure 4 and Figure 5 , the lifting column 312 can be arranged to slide on the fixed column 311.

[0092] In an optional embodiment, as shown in Figure 5 , the guide roller 314 is arranged on the opposite sides of the bracket 313 along the first direction X, and the guide groove 3120 is arranged on the opposite sides of the lifting column 312 along the first direction X. In more embodiments, the guide roller 314 and the guide groove 3120 can be arranged at other positions, such as the opposite sides of other directions, or multiple sides.

[0093] As shown in Figure 4 and Figure 5 , the fixed column 311 is a hollow structure with an open upper end, and the jacking member 91 is arranged inside the fixed column 311, and the top end of the jacking member 91 can pass through the open upper end of the fixed column 311. The purpose of this arrangement is to utilize the internal space of the fixed column 311, and at the same time, the fixed column 311 can provide some protection for the jacking member 91. In more embodiments, the lifting column 312 can be arranged side by side with the fixed column 311 on one side.

[0094] As shown in Figures 6 to 8 , the first fine adjustment module 333 includes a third lead screw 3333, a third nut 3334, and a connecting rod 3338, the third lead screw 3333 is rotatably mounted on the movable plate 332, the central axis of the third lead screw 3333 is perpendicular to the first direction X, and the third nut 3334 is engaged with the third lead screw 3333; as shown in Figure 9 , the first end of the connecting rod 3338 is rotatably mounted on the fixed plate 331 about a fourth axis N, and the other end of the connecting rod 3338 is rotatably connected to the third nut 3334 about a fifth axis L, and the fifth axis L and the fourth axis N are both parallel to the second axis Q.

[0095] When the third lead screw 3333 rotates, the third nut 3334 moves along the third lead screw 3333, as shown in Figure 9 , since the third nut 3334 is rotatably connected to the other end of the connecting rod 3338, the movable plate 332 will be pushed to rotate about the second axis Q to adapt to the length of the connecting rod 3338. As shown in Figure 9 , when the third nut 3334 slides upward along the third lead screw 3333, the included angle between the movable plate 332 and the fixed plate 331 becomes smaller.

[0096] As shown in Figure 7 and Figure 8 In one embodiment, the first fine adjustment module 333 further comprises a third guide rail 3336 and a third sliding block 3337. The third guide rail 3336 is fixedly arranged on the movable plate 332 and parallel to the central axis of the third screw rod 3333. The third sliding block 3337 is arranged on the third guide rail 3336 and fixedly connected with the third nut 3334. When the third nut 3334 moves along the third screw rod 3333, the third sliding block 3337 is driven to move along the third guide rail 3336 synchronously. The other end of the connecting rod 3338 is rotatably connected to the third sliding block 3337 around the fifth axis L.

[0097] Through the sliding configuration of the third guide rail 3336 and the third sliding block 3337, the third sliding block 3337 can limit the rotation of the third nut 3334 around the third screw rod 3333, without the need to set an additional circumferential limiting structure for the third nut 3334. Also, the torque of the third screw rod 3333 is avoided from being transmitted to the connecting rod 3338 through the third nut 3334, thereby avoiding the problems of deflection and easy jamming of the connecting rod 3338, and ensuring the smoothness of the forward and backward pitching adjustment of the movable plate 332.

[0098] In addition, through the configuration of the third guide rail 3336 and the third sliding block 3337, the connecting rod 3338 can be arranged away from the third nut 3334 in the first direction X. This is conducive to the arrangement of the structure within the first fine adjustment module 333, and also makes the second adjustment assembly 33 have a certain volume, so as to facilitate a large enough connection area with the bracket 313, the beam body 71, etc., to ensure the connection stability between the second adjustment assembly 33 and the bracket 313, the beam body 71, etc.

[0099] As shown in Figure 7 and Figure 8 In one embodiment, the third guide rail 3336 and the third sliding block 3337 are both configured as two, and are respectively located on the two sides of the third screw rod 3333 in the first direction X. The connecting rod 3338 can be configured as one group and hinged with one of the third sliding blocks 3337, or can be configured as two groups and hinged with the third sliding blocks 3337 respectively, as shown in Figure 8 .

[0100] In this way, the two third sliding blocks 3337 slide on the two sides of the third screw rod 3333 respectively, which makes the stress of the two third sliding blocks 3337 more balanced, and is conducive to the sliding of the third sliding blocks 3337.

[0101] As shown in Figure 7 and Figure 8As shown, the two third sliders 3337 are fixedly connected through a connecting rod 3340. Of course, in the second direction Y, the connecting rod 3340 avoids the third screw rod 3333.

[0102] Please continue to refer to Figure 7 and Figure 8 As shown, the first fine adjustment module 333 further includes a first bevel gear 3332 and a second bevel gear 3335 engaged with each other, the first bevel gear 3332 is coaxially connected with one end of the third screw rod 3333, for example, is fixedly connected with the upper end of the third screw rod 3333, and the second bevel gear 3335 is rotatably installed on the movable plate 332, and the central axis of the second bevel gear 3335 is perpendicular to the central axis of the first bevel gear 3332. By rotating the second bevel gear 3335, the rotation of the first bevel gear 3332 and the third screw rod 3333 can be realized.

[0103] One end of the second bevel gear 3335 is connected with the first hand wheel 3331 through a first rotating rod 3341, which is used for rotating the second bevel gear 3335 by the operator. The purpose of such arrangement is to allow the operator to operate the rotation of the third screw rod 3333 from the left side or the right side of the second adjustment assembly 33. This is taken into account, for example, Figure 1 As shown, the upper part of the second adjustment assembly 33 is generally provided with an electric control box 82, so that the rotation operation of the third screw rod 3333 can avoid the electric control box 82.

[0104] In other optional embodiments, the first bevel gear 3332 and the second bevel gear 3335 can be omitted, and the first hand wheel 3331 can be directly arranged at the upper end or the lower end of the third screw rod 3333, if the space above or below the second adjustment assembly 33 allows.

The second worm wheel 3353 is fixedly connected with the center point of the beam body 71 along the first direction X.

[0108] The rotation of the second worm 3352 can be converted into the rotation of the second worm wheel 3353, so as to realize the rotation of the beam 7 around the third axis M, which can adjust the height of the left and right sides of the beam 7.

[0109] As shown in Figure 7 and Figure 8 , the second fine adjustment module 335 comprises a third support plate 3356 fixedly arranged on the side surface of the movable plate 332 facing the fixed plate 331 (also, the third support plate 3356 is shown in a state separated from the movable plate 332), the second worm 3352 passes through the third support plate 3356 and rotates in the third support plate 3356. In an optional embodiment, a bearing (not shown) can be arranged in the third support plate 3356 for supporting the second worm 3352.

[0110] Optionally, the structure of the third support plate 3356 can also be arranged so that the third support plate 3356 supports the third screw rod 3333 at the same time, for example, supports the lower end of the third screw rod 3333.

[0111] In an embodiment, as shown in Figure 7 and Figure 8 , the second worm 3352 is located between the third nut 3334 and a third sliding block 3337, and the second worm wheel 3353 is located on the axial side of the third screw rod 3333, such as the lower end. The first fine adjustment module 333 and the second fine adjustment module 335 are arranged intersecting each other and do not affect each other, and utilize the space of each other, which makes the structural arrangement of the second adjustment assembly 33 more balanced.

[0112] In addition, in order to facilitate the rotation of the third screw rod 3333, in an embodiment, as shown in Figure 7 and Figure 8 , the second fine adjustment module 335 further comprises a third bevel gear 3354 and a fourth bevel gear 3355 engaged with each other, the third bevel gear 3354 is coaxially arranged at one end of the second worm 3352 in the axial direction, such as the upper end in the axial direction, and the fourth bevel gear 3355 is rotatably mounted on the movable plate 332, the central axis of the fourth bevel gear 3355 is perpendicular to the central axis of the third bevel gear 3354.

[0114] Likewise, the second hand wheel 3351 is provided so that the rotation of the second worm 3352 can avoid the electric control box 82. In other optional embodiments, if permitted, the second hand wheel 3351 can be directly connected to the axial upper end or the axial lower end of the second worm 3352.

[0115] In a specific embodiment, the second hand wheel 3351 and the first hand wheel 3331 are arranged relative to each other along the first direction X, and are respectively located on the left and right sides of the second adjustment component 33 , which is adapted to the operating habits of the operator.
