[0051] The base 1 is used to be placed on the ground, and the bottom of the main column 2 is connected with the base 1. The sliding sleeve 3 is sleeved on the main column 2 and can move in the vertical direction and rotate in the horizontal plane relative to the main column 2. A bearing 45 is arranged between the sliding sleeve 3 and the main column 2 to ensure smooth movement of the sliding sleeve 3 through an optimal gap. The sliding sleeve locking mechanism 4 is used to lock the height of the sliding sleeve 3 so as to keep it relatively static in the axial direction with the main column 2.

[0052] The rotating arm 5 is installed on the sliding sleeve 3 and can rotate in the vertical plane relative to the sliding sleeve 3. The rotating arm locking mechanism 6 is used to lock the rotating arm 5 so as to fix it at a certain angle. The clamping unit 7 is installed on the rotating arm 5 and is used to clamp the bicycle frame.

[0053] The counterbalance spring 9 is installed on the main column 2 and above the sliding sleeve 3. The counterbalance spring 9 comprises a steel wire rope 91, pulleys, a housing and a steel wire rope locking device, which are conventional technologies in the field and will not be described here. The lower end of the steel wire rope 91 of the counterbalance spring 9 is connected with the sliding sleeve 3, which can be used to balance the gravity of the sliding sleeve 3, the clamping unit 7 and the clamped bicycle, so as to adjust the height of the bicycle, reduce the labor burden of workers and improve the safety performance. Of course, the counterbalance spring 9 can also rotate in the horizontal plane relative to the main column 2 to adapt to the position of the sliding sleeve 3 in the horizontal circumferential direction. As a preferred embodiment, a bearing is arranged between the counterbalance spring 9 and the main column 2 to facilitate the rotation of the counterbalance spring 9.

[0054] In some embodiments, as shown in Figs. 1, Figure 4 and Figure 5 the sliding sleeve locking mechanism 4 comprises a clamping body and a first operating mechanism 44, which is used to drive the clamping body to switch between the clamping and releasing states. Specifically, the clamping body comprises an elastic sleeve 41, an inner clamping assembly 42 and a locking ferrule 43. The elastic sleeve 41 comprises a first cylinder segment 411 for sleeving on the sliding sleeve 3 and a second cylinder segment 412 for sleeving on the outside of the main column 2. The diameter of the first cylinder segment 411 is larger than that of the second cylinder segment 412. The lower end of the sliding sleeve 3 is located in the first cylinder segment 411. The inner clamping assembly 42 is arranged in the second cylinder segment 412 and between the inner wall of the second cylinder segment 412 and the outer wall of the main column 2.

[0055] The inner clamping assembly 42 comprises at least three clamping blocks 421, the inner surface of the clamping block 421 is a cylindrical surface matched with the outer surface of the main column 2, and the outer surface of the clamping block 421 is a cylindrical surface matched with the inner surface of the second barrel segment 412. The clamping blocks 421 are arranged on the outer side of the main column 2 in the circumferential direction, and the second barrel segment 412 is provided with at least three slits 413 in the circumferential direction, which divide the second barrel segment 412 into at least three tile-shaped blocks 414, the number of the tile-shaped blocks 414 is consistent with the number of the clamping blocks 421, and the clamping blocks 421 correspond to the tile-shaped blocks 414 one by one.

[0056] Preferably, the clamping blocks 421 are fixed with the tile-shaped blocks 414 respectively through screws.

[0057] It is worth noting that the number of the clamping blocks 421 is reasonably set according to needs. In the exemplary embodiment, the clamping blocks 421 are four, and the corresponding slits 413 are four.

[0058] The locking collar 43 is sleeved on the outer side of the second barrel segment 412, and the first operating mechanism 44 is used to drive the locking collar 43 to switch between locking and unlocking. When the locking collar 43 is locked, the elastic sleeve 41 is deformed inwardly to make the inner surface of the clamping block 421 tightly fit with the main column 2 to achieve fixation, thereby preventing the sliding sleeve 3 from sliding downward and fixing the sliding sleeve 3 at a certain height; when the locking collar 43 is unlocked, the elastic sleeve 41 restores the deformation outwardly under the elastic force of itself to make the inner surface of the clamping block 421 separate from the main column 2, and at this time, the height of the sliding sleeve 3 can be adjusted up and down.

[0059] Optionally, the upper end of the slit 413 extends to the middle part of the first barrel segment 411.

[0060] In some embodiments of the present application, as shown in Figure 6 , Figure 7 The locking collar 43 comprises a collar body and a locking pull rod 432, one end of the collar body is provided with a first connecting part 433, the other end of the collar body is provided with a second connecting part 434, one end of the locking pull rod 432 is connected with the first connecting part 433, the other end of the locking pull rod 432 passes through a through hole in the second connecting part 434 and is connected with the first operating mechanism 44, and the gap between the first connecting part 433 and the second connecting part 434 can be adjusted through the first operating mechanism 44, thereby realizing the locking and unlocking of the locking collar 43.

[0061] Optionally, the locking collar 43 further comprises a locking block 435, the locking block 435 is located between the first connecting part 433 and the second connecting part 434 and abuts against the second connecting part 434, the locking pull rod 432 passes through a through hole in the locking block 435, and the locking block 435 is fixedly connected with the elastic sleeve 41 through a screw hole 436.

[0062] In some embodiments of the present application, the first operating mechanism 44 comprises a first gap adjusting block 441 and a first operating lever 442. The first gap adjusting block 441 is rotatably connected to one end of the locking pull rod 432 through a shaft A 443, which is perpendicular to the axis of the locking pull rod 432. A first top pin 444 is fixedly arranged on the second connecting portion 434, and a first gap adjusting surface 445 adapted to the first top pin 444 is arranged on the first gap adjusting block 441. The first operating lever 442 is connected to the first gap adjusting block 441 and used to rotate the first gap adjusting block 441 around the shaft A 443. As the contact position of the first top pin 444 with the first gap adjusting surface 445 changes, the gap between the first gap adjusting block 441 and the second connecting portion 434 also changes, thereby changing the gap between the first connecting portion 433 and the second connecting portion 434 through the locking pull rod 432, so as to realize the locking and unlocking of the body of the thimble.

[0063] Optionally, as shown in FIG. 4, a first positioning groove 446 adapted to the first top pin 444 is arranged on the first gap adjusting surface 445 of the first gap adjusting block 441, and the end of the first top pin 444 can be sunk into the first positioning groove 446 to realize the gap locking. Figure 8

[0064] It is worth noting that the first gap adjusting surface 445 can be a slope or an arc surface. Optionally, the first gap adjusting block 441 is a cam, and the first positioning groove 446 is arranged at the vertex position of the cam.

[0065] The above describes that the first operating mechanism 44 comprises the first gap adjusting block 441 and the first operating lever 442. However, the present application is not limited thereto. Specifically, in some embodiments, the first operating mechanism 44 comprises an adjusting nut, which is threadedly connected to the locking pull rod 432. Rotating the adjusting nut can drive the pull rod to move axially, thereby tightening or loosening the locking thimble 43. This is a conventional technique in the art, which will not be described here.

[0066] The above describes that the sliding sleeve locking mechanism 4 comprises the clamping body and the first operating mechanism 44. However, the present application is not limited thereto. In other embodiments, the sliding sleeve locking mechanism 4 comprises a locking bolt arranged on the sliding sleeve 3, and the corresponding main column 2 is provided with a plurality of bolt holes or positioning grooves adapted to the locking bolt. The fixing of the sliding sleeve 3 can be realized by screwing the locking bolt into a certain bolt hole or withdrawing it. This is a conventional technique in the art, which will not be described here.

[0067] In some embodiments, as shown in FIG. 4, the first gap adjusting block 441 is rotatably connected to the first operating lever 442 through a shaft B 444, which is perpendicular to the axis of the first operating lever 442. Figure 4 ​As shown, the rotating arm 5 is connected with the sliding sleeve 3 through a horizontal shaft 51, and the rotating arm locking mechanism 6 is connected with the horizontal shaft 51 to fix the angle of the rotating arm 5.

[0068] In some embodiments, as shown in Figure 9 , Figure 10 As shown, the rotating arm locking mechanism 6 comprises a seat body 60, a locking device, and a second operating mechanism. The seat body 60 is fixed with the sliding sleeve 3 through screws or bolts or other means. The locking device comprises a locking gear 61 and a gear lock block 62 for cooperating with the locking gear 61. The locking gear 61 is installed on the horizontal shaft 51, and the gear lock block 62 is installed on the seat body 60 and can move linearly relative to the locking gear 61. The gear lock block 62 has a locking position and an unlocking position. When the gear lock block 62 is in the locking position, the gear lock block 62 is engaged with the locking gear 61. When the gear lock block 62 is in the unlocking position, the gear lock block 62 is separated from the locking gear 61.

[0069] The second operating mechanism is used to drive the gear lock block 62 to move linearly relative to the locking gear 61, so as to switch the locking gear 61 between the locking position and the unlocking position. It is worth mentioning that there are many linear motion driving mechanisms, such as gear and rack, screw and nut, etc., which can be reasonably set according to needs by those skilled in the art.

[0070] In some embodiments of the present application, as shown in Figure 10 The second operating mechanism comprises a second gap adjusting block 63, a second operating rod 64, and a spring 65. The second gap adjusting block 63 is connected with the seat body 60 through a shaft B 66, and the shaft B 66 is perpendicular to the axis of the locking gear 61. The gear lock block 62 is provided with a second top pin 66, and the second gap adjusting block 63 is provided with a second gap adjusting surface 631 adapted to the second top pin 66. The spring 65 acts on the gear lock block 62, and under the action of the spring 65, the end of the second top pin 66 abuts against the second gap adjusting surface 631 of the second gap adjusting block 63. The second operating rod 64 is connected with the second gap adjusting block 63 and is used to rotate the second gap adjusting block 63 around the shaft B 66. With the change of the contact position of the second top pin 66 and the second gap adjusting surface 631, the gear lock block 62 also moves, and the gap between the locking gear 61 and the gear lock block 62 also changes, so as to realize locking and unlocking.

[0071] Optionally, as shown in Figure 11As shown, the second gap adjustment block 63 has a second gap adjustment surface 631, and a second positioning groove 632 is provided on the second gap adjustment surface 631 to accommodate the second top pin 66, the end of the second top pin 66 can be inserted into the second positioning groove 632 to achieve gap locking. In the exemplary embodiment, as shown, when the gear lock block 62 is in the locked position, the end of the second top pin 66 falls into the second positioning groove 632; at this time, rotating the second gap adjustment block 63, the end of the second top pin 66 is withdrawn from the second positioning groove 632 and moves to the right under the pulling force of the spring 65 and synchronously drives the gear lock block 62 to move to the right, and finally the gear lock block 62 moves to the unlocked position, achieving the separation of the gear lock block 62 and the locking gear 61.

[0072] As a preferred, the second top pin 66 is a ball head pin, and the second positioning groove 632 is a spherical groove matched with the ball head pin.

[0073] It is worth noting that the second gap adjustment surface 631 can be a slope, a curved surface, etc. Optionally, the second gap adjustment block 63 is a cam, and the second positioning groove 632 is located at the vertex position of the cam.

[0074] In some embodiments, as shown, Figure 10 The seat body 60 is provided with a telescopic rod 68, the other end of the telescopic rod 68 is connected with the gear lock block 62, and the spring 65 is sleeved on the telescopic rod 68. As a preferred, the seat body 60 is provided with a telescopic rod adjusting nut 69, the telescopic rod adjusting nut 69 is threadedly connected with the seat body 60, one end of the telescopic rod 68 is arranged in the hole in the telescopic rod adjusting nut 69, and the two ends of the spring 65 are arranged on the gear lock block 62 and the telescopic rod adjusting nut 69 respectively. In order to further increase the stability of the movement of the gear lock block 62, the telescopic rod 68 has two, and the two telescopic rods 68 are symmetrically arranged on the two sides of the second top pin 66; correspondingly, the spring 65 has two.

[0075] When the gear lock block 62 is switched to the unlocked position to facilitate angle adjustment, in order to avoid the rotation of the rotating arm 5 under the gravity of the bicycle, the stability of angle adjustment is increased. In some embodiments of the present application, a damping device 8 is further provided, as shown in Figure 4 、 Figure 9 and Figure 12 The damping device 8 includes a indexing sleeve 81 and a round head spring pin 82, the indexing sleeve 81 is sleeved on the horizontal shaft 51 and can rotate with the horizontal shaft 51, a plurality of indexing grooves 83 matched with the round head spring pin 82 are arranged on the outer circular surface of the indexing sleeve 81 in the circumferential direction, the free end of the round head spring pin 82 is clamped into one of the indexing grooves 83 under the self elastic force, thereby hindering the rotation of the indexing sleeve 81, the horizontal shaft 51 and the rotating arm 5 in the vertical plane; but when the rotating external force increases to a certain extent, the round head spring pin 82 can be forced to retract, thereby rotating the rotating arm 5 in the vertical plane.

[0076] It is worth mentioning that the number of the index grooves 83 can be set according to the actual situation. Of course, the index grooves 83 are smoothly connected with the outer surface of the index sleeve 81 so as to facilitate the free end of the round head spring pin 82 to slide into or out of the index grooves 83.

[0077] Of course, the damping device 8 further comprises a cover 84 which covers the outside of the index sleeve 81 and is fixed to the sliding sleeve 3 by screws or other means. The round head spring pin 82 is installed in the cover 84; as a preferred, the cover 84 is provided with a spring force adjusting nut 85, and the spring force of the round head spring pin 82 can be adjusted by the spring force adjusting nut 85.

[0078] As a preferred, the top of the cover 84 is provided with a wire rope bracket shaft 86, and one end of the wire rope 91 of the counterbalance spring 9 is connected with the wire rope bracket shaft 86.

[0079] In some embodiments of the present application, as shown in Figure 4 , Figure 5 The sliding sleeve 3 comprises a vertical cylinder 31 and a horizontal cylinder 32, the vertical cylinder 31 covers the outside of the main column 2, and the horizontal shaft 51 is arranged in the horizontal cylinder 32 and is rotationally connected with the horizontal cylinder 32 by bearings. The rotating arm 5 is fixedly connected with the horizontal shaft 51. As a preferred, the vertical cylinder 31 and the horizontal cylinder 32 are integrally manufactured. As shown in Figure 9 The cover 84 is fixed to the horizontal cylinder 32 by screws or other means.

[0080] The clamping unit 7 can be an inner expanding clamping tool or an outer clamping clamping tool. As a preferred, the clamping unit 7 is detachably connected with the rotating arm 5, so that different clamping tools can be replaced according to different vehicle models to meet the needs of different vehicle models.

[0081] In some embodiments of the present application, as shown in Figure 13 The clamping unit comprises a first clamping arm 71, a second clamping arm 72, an elastic mechanism and a locking mechanism 74, the first clamping arm 71 is rotationally connected with the second clamping arm 72 by a shaft 75, and both of them have a clamping portion 70 at one end.

[0082] The elastic mechanism acts on the first clamping arm 71 and the second clamping arm 72, and under the action of the elastic mechanism, the clamping portion 70 of the first clamping arm 71 and the clamping portion 70 of the second clamping arm 72 have a tendency to separate.

[0083] The locking mechanism 74 is used to drive the clamping portion 70 of the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 to close and clamp and keep in the clamped state and to realize unlocking. Specifically, as shown in Figure 14As shown, the locking mechanism 74 includes a pull rod 741, an abutment block 742, a cam 743, and a wheel axle 744. One end of the pull rod 741 is connected to the first clamping arm 71, and the other end of the pull rod 741 has an opening for mounting the wheel axle 744. The axial direction of the wheel axle 744 is perpendicular to the axial direction of the pull rod 741. The cam 743 is mounted on the wheel axle 744 and can rotate around the wheel axle 744.

[0084] Both the second clamping arm 72 and the abutment block 742 have pull rod holes that are compatible with the pull rod 741. The pull rod 741 is installed in the pull rod holes of the second clamping arm 72 and the abutment block 742.

[0085] The abutment block 742 includes a first abutment portion for abutting against the second clamping arm 72 and a second abutment portion for abutting against the cam 743 and matching the wheel surface of the cam 743. Under the action of the elastic mechanism, the second clamping arm 72 can push the abutment block 742 so that the second abutment portion of the abutment block 742 abuts against the cam 743. Rotating the cam 743 can cause the abutment block 742 to slide linearly along the pull rod 741 in both directions, thereby switching the clamping portion 70 of the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 between clamping and locking. After unlocking, the clamping portions 70 of the second clamping arm 72 and the first clamping arm 71 can be springed apart under the action of the elastic mechanism. At the same time, due to the presence of the abutment block 742 and the cam 743, the spring-off distance can be controlled, so that the interval between the clamping portions 70 of the first clamping arm 71 and the clamping portions 70 of the second clamping arm 72 can vary within a suitable range. To facilitate the rotation of cam 743, cam 743 is connected to handle 745.

[0086] like Figure 14 As shown, at this time, the abutment block 742 is furthest from the rotation point of the cam 743, and the first clamping arm 71 and the second clamping arm 72 are in a clamping state; when the cam 743 is operated to rotate counterclockwise or clockwise by the handle 745, the cam 743 and the second clamping arm 72 move to the left under the elastic force of the elastic mechanism, the distance between the second clamping arm 72 and the first clamping arm 71 increases, and then the clamped part is released.

[0087] To further improve stability, such as Figure 14 , Figure 15 As shown, the second clamping arm 72 has a groove 721 on one side relative to the first clamping arm 71 for accommodating the abutment block 742. The first abutting part of the abutment block 742 is inserted into the groove 721 and matches the shape of the groove 721. Preferably, the contact surface between the first abutting part and the groove 721 is spherical, which can reduce friction, distribute force more evenly, and increase flexibility.

[0088] In an exemplary embodiment, the elastic mechanism includes a tension spring 73, with both ends of the tension spring 73 respectively mounted on the first clamping arm 71 and the second clamping arm 72, and the elastic mechanism is always kept in a stretched state.

[0089] It is worth mentioning that the second clamping arm 72 rotates around the shaft 75 in a certain angle range during the switching between the clamping and releasing states, so the pull rod hole in the second clamping arm 72 is a circular slot.

[0090] In the exemplary embodiment, the other end of the pull rod 741 is a flat portion 7411, and two cams 743 sandwich the flat portion 7411, with the plane of the flat portion 7411 in contact with the end faces of the cams 743. One end of the handle 745 is connected to the two cams 743. Preferably, the handle 745 is integrally manufactured with the cams 743.

[0091] The above describes the elastic mechanism as including a tension spring 73. However, the present application is not limited thereto. Specifically, in some embodiments, the elastic mechanism is a torsion spring, which can be sleeved on the shaft 75. In other embodiments, the elastic mechanism is a compression spring, which is compressed between the second clamping arm 72 and the first clamping arm 71, so that the second clamping arm 72 and the clamping portion 70 of the first clamping arm 71 have a tendency to separate. This is a conventional technique in the art, which will not be described here.

[0092] As shown in Figure 9 , a plurality of connection holes 711 are provided at the end of the first clamping arm 71 away from the clamping portion 70. The end of the first clamping arm 71 away from the clamping portion 70 is bolted to the rotating arm 5 through the connection holes 711. If necessary, the clamping unit can be conveniently removed and replaced with other types of clamping units.

[0093] In some embodiments, a nylon clamping block 76 can be detachably installed at the clamping portion 70 of the first clamping arm 71 and the second clamping arm 72, which is used to directly contact the clamped object, so as to not only avoid damaging the paint on the surface of the bicycle frame, but also to replace different nylon clamping blocks 76 according to the size and shape of different frames.

[0094] Since the bicycle assembly single-line machine table of the present embodiment is directly placed on the ground through its base 1, and most production workshops have painted floors, in order to avoid using screws to fix the base 1, in the preferred embodiment, the base 1 includes a base plate 11 having a flat bottom surface, and the bottom of the main column 2 is connected to the base plate 11. By using the base plate 11 to contact the ground over a large area to increase the friction between them, the position is fixed by the weight of the reliable equipment, as shown in Figure 16 , Figure 17 .

[0095] In addition, since the device is heavy, in order to move the whole bicycle assembly line, in some embodiments, the base 1 further comprises a liftable moving mechanism and a lifting adjusting mechanism. The liftable moving mechanism comprises a pressing plate 12 and at least three universal wheels 13, the universal wheels 13 are installed on the pressing plate 12, and the base 11 has a corresponding avoiding hole 111 for each universal wheel 13. Of course, the heights of all the universal wheels 13 are consistent.

[0096] The lifting adjusting mechanism is used to adjust the height of the pressing plate 12, and can drive the pressing plate 12 to switch between a first position and a second position. When the pressing plate 12 is in the first position, the bottom of the universal wheel 13 is higher than the bottom surface of the base 11. When the pressing plate 12 is in the second position, the bottom of the universal wheel 13 is lower than the bottom surface of the base 11.

[0097] In the initial state, the pressing plate 12 is in the first position, and the bottom surface of the base 11 is in contact with the ground. The bottom of the universal wheel 13 is higher than the bottom surface of the base 11, and is not in contact with the ground. Then, the pressing plate 12 is driven downward to the second position by the lifting adjusting mechanism. The pressing plate 12 synchronously drives the universal wheel 13 to move downward from the corresponding avoiding hole 111 of the base 11, so that the bottom of each universal wheel 13 is lower than the bottom surface of the base 11. At this time, the universal wheel 13 replaces the base 11 to contact the ground, and the base 11 is lifted away from the ground under the driving of the reaction force. The friction between the base 11 and the ground is removed, and the plurality of universal wheels 13 contact the ground. At this time, the whole mechanism and the device main body on the mechanism can be easily moved. When the moving lifting universal mechanism and the device main body installed thereon are moved to a predetermined position by the universal wheel 13, the pressing plate 12 is driven upward by the lifting adjusting mechanism, and then the universal wheel 13 is lifted upward to be away from the ground. At the same time, the base 11 is in contact with the ground under the action of the reaction force, so as to fix the device in the new position.

[0098] It is worth noting that the lifting adjusting mechanism can be a manual lifting adjusting mechanism or an automatic lifting adjusting mechanism. In the exemplary embodiment, the lifting adjusting mechanism is a manual adjusting mechanism. Specifically, as shown in Figure 16 、 Figure 17 The lifting adjusting mechanism comprises an adjusting sleeve 14, an adjusting nut 15 and a main spring 16. The bottom end of the adjusting sleeve 14 is connected with the base 11, and the outer surface of the adjusting sleeve 14 has an outer thread matched with the adjusting nut 15. The adjusting nut 15 is threadedly connected with the adjusting sleeve 14.

[0099] The adjusting sleeve 14 passes through the hole on the pressing plate 12, the pressing plate 12 can move up and down along the adjusting sleeve 14, the main spring 16 is arranged between the pressing plate 12 and the bottom plate 11, under the action of the main spring 16, the pressing plate 12 has a tendency to move upward away from the bottom plate 11. The adjusting nut 15 is located above the pressing plate 12, and the adjusting nut 15 is screwed downward to move downward, the pressing plate 12 is pressed downward by the adjusting nut 15 to overcome the elastic force of the main spring 16 and then moves downward, and the universal wheel 13 is driven to move downward from the corresponding avoiding hole 111 of the bottom plate 11 to the bottom of the wheel below the bottom surface of the bottom plate 11, at this time, the universal wheel 13 replaces the bottom plate 11 to contact the ground; similarly, the adjusting nut 15 is screwed upward, the adjusting nut 15 moves upward, the pressing plate 12 is lifted upward under the action of the main spring 16 to leave the ground, and the bottom plate 11 is also driven to contact the ground again under the action of the reaction force. In order to facilitate the screwing of the adjusting nut 15, the adjusting nut 15 is provided with a wrench hole.

[0100] The lifting adjusting mechanism described above is a manual adjusting mechanism. However, the present application is not limited thereto. Specifically, in other embodiments, the lifting adjusting mechanism is an automatic lifting adjusting mechanism installed on the adjusting sleeve 14, the automatic lifting adjusting mechanism can drive the pressing plate 12 to move up and down, and the automatic lifting adjusting mechanism can be an electric lifting adjusting mechanism or a hydraulic lifting adjusting mechanism or a pneumatic lifting adjusting mechanism. The electric lifting adjusting mechanism can be an electric push rod, the hydraulic lifting adjusting mechanism can be a hydraulic cylinder, and the pneumatic lifting adjusting mechanism can be a pneumatic cylinder.

[0101] In order to make the base 1 more stable as a whole, the adjusting sleeve 14 is connected to the center of the bottom plate 11, the adjusting sleeve 14 passes through the center hole of the pressing plate 12 and fits with the gap therebetween, and the universal wheels 13 are uniformly arranged on the same circumference around the center hole of the pressing plate 12.

The plurality of supporting rods 17 have a certain guiding effect on the pressing plate 12, and can prevent the pressing plate 12 from rotating relative to the adjusting sleeve 14, so as to ensure that the universal wheels 13 are always located directly above the corresponding avoiding hole 111 of the bottom plate 11.

[0103] It is worth mentioning that the main spring 16 can be sleeved on the adjusting sleeve 14, and several main springs 16 can be evenly arranged around the adjusting sleeve 14. In the exemplary embodiment, there is one main spring 16 sleeved on the adjusting sleeve 14; several secondary springs 18 are arranged between the pressing plate 12 and the bottom disc 11, and the several secondary springs 18 are evenly arranged on the same circle around the main spring 16. Preferably, the number of the secondary springs 18 is consistent with the number of the supporting rods 17, the secondary springs 18 are sleeved outside the supporting rods 17 one by one, the upper end of the secondary spring 18 is connected with the pressing plate 12, and the lower end of the secondary spring 18 is a free end or is connected to the bottom disc 11. When the pressing plate 12 moves downward to be close to the bottom disc 11, the secondary spring 18 can play a certain buffering and damping effect.

[0104] It is worth mentioning that the number of the universal wheels 13 is reasonably set according to needs, and three universal wheels 13 can basically meet the needs of stable movement. In the exemplary embodiment, there are four universal wheels 13, and the corresponding four avoiding holes 111 are also provided. Preferably, the supporting rods 17 also have four supporting rods 17.

[0105] The shape of the bottom disc 11 and the avoiding holes 111 is reasonably set according to needs; preferably, the bottom disc 11 is a circular disc, and the avoiding holes 111 are circular holes.

[0106] In order to avoid the feet of the operator from touching the universal wheels 13 during operation, the universal wheels 13 can be folded in some embodiments of the present application. Specifically, the universal wheels 13 are installed on the reversible wheel frames 131, the wheel frames 131 are rotationally connected with the pressing plate 12 through the horizontally arranged shaft C132, and the universal wheels 13 can be folded by being flipped upward around the shaft C132 as the rotation center; at the same time, in order to prevent the universal wheels 13 from being folded during walking after the pressing plate 12 is moved downward to the second position, a wheel frame pressing plate 133 is arranged on the pressing plate 12 for each universal wheel 13, the wheel frame pressing plate 133 is used to block the wheel frame 131 to prevent it from being flipped upward, one end of the wheel frame pressing plate 133 is rotationally connected with the pressing plate 12 through a vertical shaft, and the wheel frame pressing plate 133 can be switched between the first position and the second position by rotating the wheel frame pressing plate 133; when the wheel frame pressing plate 133 is located at the first position, the wheel frame pressing plate 133 can be blocked above the wheel frame 131 to prevent the wheel frame 131 from being flipped upward, please refer to Figure 16 At this time, the wheel frame pressing plate 133 is located at the first position; when the wheel frame pressing plate 133 is located at the second position, the wheel frame pressing plate 133 is staggered with the wheel frame 131, and the wheel frame 131 can be flipped upward.

[0107] As Figure 18As shown, in the exemplary embodiment, the frame of the bicycle 10 is fixed on the bicycle whole-vehicle assembly single-line machine table by the clamping unit 7, the slide sleeve locking mechanism 4 is unlocked, and the bicycle 10 will not fall rapidly under the action of gravity due to the action of the balance spring 9. A worker slightly applies a little human force to adjust the height of the bicycle 10 according to the height of the worker, then locks the slide sleeve locking mechanism 4, fixes the bicycle 10 at the appropriate height, and then assembles parts on the bicycle frame. During the assembly process, the worker can rotate the bicycle frame in the horizontal plane according to the standing position and operation requirements, or adjust the angle of the bicycle frame in the vertical plane through the rotating arm 5 and the rotating arm locking mechanism 6. When the assembly is completed, the slide sleeve locking mechanism 4 is unlocked, and the worker slightly applies a little human force to lower the assembled bicycle 10 to the ground, completes the unloading, and provides the greatest convenience for the assembly work.

[0108] Moreover, when it is necessary to assemble the bicycle in another position, the universal wheel 13 can be lowered through the lifting adjustment mechanism, and then the equipment and the bicycle to be assembled can be easily moved. Then the universal wheel 13 is raised, the chassis is in contact with the ground again, and the position is fixed by using reliable equipment and the weight of the bicycle to be assembled, which saves time and effort and is convenient to operate. Moreover, the chassis and the ground are not easy to slide, have good stability, and are safe to use.

Between; the adjusting nut (15) is located above the pressure plate (12). Tightening the adjusting nut (15) downwards causes the pressure plate (12) to move downwards and drive the universal wheel (13) to move down from the corresponding clearance hole (111) of the chassis (11) until the bottom of the wheel is lower than the bottom surface of the chassis (11); when the adjusting nut (15) is tightened upwards, the pressure plate (12) moves upwards under the action of the main spring (16) until the bottom of the universal wheel (13) is higher than the bottom surface of the chassis (11); the main spring (16) may or may not be fitted on the adjusting sleeve (14).
