Correspondingly, the portion of the first steel wire 51 inside the sheath 52 will also be wound around the sheath 52. The upper end of the first steel wire 51 is movably connected to the handle 3 and / or the column 2, and the lower end is connected to the locking device. The upper end of the sheath 52 is connected to the column 2 and / or the handle 3, and the lower end is connected to the main support 1. Pulling the upper end of the first steel wire 51 can unlock the locking device by linking the lower end of the first steel wire 51.

[0039] The upright column 2 can be moved up and down relative to the main support 1, that is, the height of the handle 3 can be adjusted up and down, so that the scooter of the present invention can be adapted to children of different heights.

[0040] The locking device includes a locking member 61 that can move relative to the main support 1, a locking part 62 disposed on the locking member 61, and a mating part 41 disposed on the pedal 4 that can cooperate with the locking part 62. When the locking part 62 and the mating part 41 are engaged, the main support 1 and the pedal 4 cannot rotate relative to each other, the locking device is in a locked state, and the scooter of the present invention cannot be folded.

[0041] In this embodiment, the locking part 62 is configured as a locking pin, and the mating part 41 is configured as a locking groove. When the locking pin is engaged in the locking groove, the main bracket 1 and the pedal 4 cannot rotate relative to each other. The locking pin can be integrally formed on the locking member 61, or it can be a separately configured locking pin connected to the locking member 61. That is, the locking member is provided with a connecting hole, the locking pin is connected to the connecting hole, and the locking pin is at least partially located outside the connecting hole so that it can be engaged in the locking groove.

[0042] The locking device further includes a first elastic reset member 63 disposed between the locking member 61 and the main support 1. When the locking part 62 and the mating part 41 are in position, the locking member 61 moves under the action of the first elastic reset member 63 so that the locking part 62 automatically engages with the mating part 41, thus making the operation more convenient.

[0043] In the embodiment, the lower end of the first steel wire 51 is connected with the locking device through the first linkage device and the second linkage device, the lower end of the first steel wire 51 is connected with the second linkage device, one side of the first linkage device is connected with the locking device, and the other side of the first linkage device is connected with the second linkage device; when the upper end of the first steel wire 51 is pulled, the lower end of the first steel wire 51 pulls the second linkage device, and the first linkage device is driven by the moving second linkage device to unlock the locking device.

[0044] In the embodiment, the first linkage device comprises a pulley 71 and a flexible cable 72, the pulley 71 is connected with the locking member 61 in a relative rotation manner, the flexible cable 72 passes through the pulley 71, one end of the flexible cable 72 is connected with the main support 1, and the other end of the flexible cable 72 is connected with the second linkage device; when the other end of the flexible cable 72 is pulled, the pulley 71 and the locking member 61 are driven to move, so that the locking part 62 moves to the direction of the disengagement part 41 to realize the unlocking of the locking device; and the pulley 71 rotates relative to the locking member 61 in the moving process, so that the pulley 71 realizes the mode of a movable pulley 71. In this way, only a small pulling force needs to be applied to the other end of the flexible cable 72 to pull the locking member to move and make the locking part disengage from the cooperation part. Preferably, the locking member 61 is provided with a receiving groove 611, and the pulley 71 is connected with the receiving groove 611 in a rotation manner through a rotating shaft (not shown in the figure).

[0046] In the embodiment, the linkage part comprises a first linkage member 74 and a second linkage member 75, the first linkage member 74 and the second linkage member 75 are connected with the main support 1 and can move up and down together relative to the main support 1, the lower end of the first steel wire 51 is connected with the first linkage member 74, when the lower end of the first steel wire 51 pulls the first linkage member 74 to move up, the second linkage member 75 moves up together, and the driving member 73 is driven by the moving second linkage member 75 to move, so as to pull the other end of the flexible cable 72. Because only a small pulling force needs to be applied to the other end of the flexible cable 72 to unlock the locking device, the force required to pull the first steel wire 51 is also small, that is to say, the unlocking operation of the locking device of the present application is particularly easy and effortless.

[0047] In the embodiment, the second linkage 75 is located below the driving member 73, so that when the second linkage 75 moves upward, the driving member 73 is driven to move upward, thus pulling one end of the flexible cable 72. Preferably, when the locking device is in the locked state, the upper end of the second linkage 75 abuts against the lower end of the driving member 73, so that as soon as the second linkage 75 moves upward, the driving member 73 is driven to move upward, thus unlocking the locking device. In this way, the locking device can be unlocked without the upper end of the first steel wire 51 moving too long, thus making the unlocking operation faster.

[0048] The main support 1 comprises a front support 11 and a bridge support 12, the lower end of the stand 2 is movably arranged in the front support 11, the front side of the bridge support 12 is rotatably connected to the front support 11, the front side of the pedal 4 is pivotally connected to the rear side of the bridge support 12, the locking device is arranged between the bridge support 12 and the pedal 4, the locking member 61 is movably connected in the bridge support 12, and one end of the flexible cable 72 is connected to the bridge support 12.

[0049] The bridge support 12 comprises a sleeving member 121 rotatably sleeved outside the front support 11 and a bridging member 122 connected to the sleeving member 121, and the interiors of the sleeving member 121 and the bridging member 122 are communicated.

In the embodiment, the first linkage 74 is movably arranged in the front support 11, the second linkage 75 and the driving member 73 are both arranged outside the main support 1 and in the sleeving member 121, and the first linkage 74 and the second linkage 75 are connected with the front support and can move upward and downward together with the front support. Preferably, the second linkage 75 is movably sleeved outside the front support 11.

[0050] The sleeving member 121 comprises a sleeving portion 1211 rotatably sleeved outside the front support 11 and a connecting portion 1212 extending outward from one side of the sleeving portion 1211, and the front end of the bridging member 122 is fixedly connected to the connecting portion 1212.

[0051] Preferably, corresponding first guide devices are arranged between the driving member 73 and the inner wall of the sleeving portion 1211. In the embodiment, the first guide grooves 1213 extending upward and downward are arranged on the inner wall of the sleeving portion 1211, and the first guide blocks 731 are arranged on the driving member 73.Figure 8 The first guide block 731 extends into the first guide slot 1213, and the first guide block 731 and the first guide slot 1213 constitute the first guide device.

[0052] The first linkage member 74 and the front support 11 are provided with a second elastic reset member 76, and the first linkage member 74 keeps a tendency to move downward under the action of the second elastic reset member 76. Specifically, the front support 11 is provided with a first connecting hole 110, and the first linkage member 74 is provided with an accommodating long hole extending upward and downward, and a first connecting member (rivet or screw, pivot or the like, not shown in the figure) penetrates through the first connecting hole and the accommodating long hole. The second elastic reset member 76 is provided as a compression spring, and the compression spring is arranged in the accommodating long hole, and the upper end of the compression spring abuts against the first connecting member, and the lower end of the compression spring abuts against the bottom wall of the accommodating long hole.

[0053] The bridge member 122 is further provided with a tensioning member 77, and one end of the flexible cable 72 or the lower end of the first steel wire passes through the tensioning member 77 and then passes through the pulley 71, and then is connected with the bridge member 122. The tensioning member 77 can be provided as a roller that can rotate relative to the bridge member 122, or can be provided as a roller that is fixed relative to the bridge member 122. In this way, the flexible cable 72 can be kept in a tensioned state when the scooter is in an unfolded state, and the flexible cable 72 can be guided to move along a route when the flexible cable 72 is pulled.

[0055] The scooter further comprises an unlocking device 8 arranged on the stand 2 or handle 3, and the upper end of the first steel wire 51 is connected to the unlocking device. The first steel wire 51 is pulled to move the upper end thereof to unlock the locking device by operating the unlocking device 8. In the embodiment, the unlocking device comprises a first connecting seat 81 arranged in the stand 2, and an operating member 82 connected to the outside of the stand 2. The first connecting seat 81 is connected to the operating member 82 and can move up and down relative to the stand 2, and the upper end of the first steel wire 51 is connected to the first connecting seat 81. Specifically, a second long hole 200 is arranged on the side wall of the stand 2, and corresponding connecting holes (not shown) are arranged on the first connecting seat 81 and the operating member 82. A connecting member (rivet, screw, etc.) passes through the connecting holes on the first connecting seat 81 and the operating member 82 and the second long hole 200 on the stand 2, so that the first connecting seat 81 and the operating member 82 can move up and down relative to the stand 2 after being connected.

[0056] When the scooter is folded, the operating member 82 is moved upward, which drives the first connecting seat 81 to move upward, so that the upper end of the first steel wire 51 is pulled to move upward. The first steel wire 51 is also moved relative to the sheath 52. Regardless of the number of turns of the first sheath steel wire 5, the lower end of the first steel wire 51 is driven to move by the same distance as the upper end, so that the first linkage 74 is pulled to move upward relative to the front support 11. When the first linkage 74 moves upward, the second linkage 75 is driven to move upward, so that the driving member 73 is also driven to move upward, and the end of the flexible cable 72 connected to the driving member 73 is also pulled to move upward. In this way, the pulley 71 and the locking member 61 are driven to move away from the pedal 4. During the movement of the pulley 71 and the locking member 61, the pulley 71 also rotates relative to the locking member 61. The movement of the locking member 61 allows the locking portion 62 to disengage from the cooperating portion 41, so that the locking device is unlocked, the main support 1 can rotate relative to the pedal 4, the stand 2 and the handle 3 rotate together with the main support 1 to move close to the pedal 4, and the scooter is folded.

[0057] Specifically, assuming only steel wire is used and no winding is set, and assuming the first linkage 74 and the second linkage 75 need to move up 10 cm to make the driving member 73 move up to a position where the pulley 71 can be pulled by the flexible cable 72 to unlock the locking device with the locking member 61, and assuming that when the upright column 2 is at the highest position relative to the main support 1, the steel wire is in a straightened state, at this time, if the unlocking device 8 is operated to drive the upper end of the steel wire to move up 10 cm, the lower end of the steel wire will also move up 10 cm, the first linkage 74 will move up, and the second linkage 75 will also move up 10 cm, and the driving member 73 can be driven by the second linkage 75 to move up to a position where the pulley 71 can be pulled by the flexible cable 72 to unlock the locking device with the locking member 61. However, if the upright column 2 moves down to a lower position relative to the front support 11, because the upper end of the steel wire will also move down together, the middle of the steel wire will be passively stacked together at this time. At this time, operating the unlocking device 8 to drive the upper end of the first steel wire 51 to move up 10 cm, but because the steel wire is stacked together at this time, the lower end of the steel wire cannot also move up 10 cm, and even the lower end of the steel wire cannot be pulled, i.e., the movement is 0. In this way, the first linkage 74 and the second linkage 75 cannot move up 10 cm, and even cannot move up at all, so that the driving member 73 cannot move up enough to pull the pulley 71 by the flexible cable 72 to unlock the locking device with the locking member 61.

[0058] The present application adopts the sheathed steel wire 5, and the sheathed steel wire 5 is arranged in a coil, so that no matter where the upper end of the first steel wire 51 is located, that is, no matter what relative height the stand 2 and the handle 3 are located relative to the main support 1, as long as the upper end of the first steel wire 51 is pulled by a distance, the lower end of the first steel wire 51 will also move by a distance, that is, with the up and down movement of the stand 2 and the handle 3 relative to the main support 1, only the size of the coil of the sheathed steel wire 5 changes, when the stand 2 and the handle 3 move upwards, the upper end of the first steel wire 51 moves upwards, and the coil of the sheathed steel wire 5 becomes smaller; when the stand 2 and the handle 3 move downwards, the upper end of the first steel wire 51 moves downwards, and the coil of the sheathed steel wire 5 becomes larger; but the coil always exists, and no matter how large or small the coil is, as long as the upper end of the first steel wire 51 is pulled by a distance, the lower end of the first steel wire 51 will also move by a distance. Specifically, when the stand 2 and the handle 3 are at the highest position relative to the main support 1, and it is assumed that the upper end of the first steel wire 51 is pulled by 10 cm by operating the unlocking device, then the lower end of the first steel wire 51 also moves by 10 cm, which enables the first linkage 74 and the second linkage 75 to drive the driving member 73 to move to a position where the flexible cable 72 can be pulled to move the pulley 71 and the locking member 61 to unlock the locking device; when the stand 2 and the handle 3 are at the lowest position relative to the main support 1, although the coil of the first sheathed steel wire 5 becomes larger as the stand 2 and the handle 3 move downwards, when the upper end of the first steel wire 51 is pulled by 10 cm by operating the unlocking device, the lower end of the first steel wire 51 also moves by 10 cm, so that the driving member 73 can still be driven by the first linkage 74 and the second linkage 75 to move to a position where the flexible cable 72 can be pulled to move the pulley 71 and the locking member 61 to unlock the locking device.

[0059] In summary, because the present application adopts the first sheathed steel wire 5 arranged as described above, no matter what height the stand 2 and the handle 3 are relative to the main support 1, pulling the upper end of the first steel wire 51 can unlock the locking device, thereby ensuring the height adjustment function of the handle 3 of the present application and the stability of the folding operation of the scooter; and no other complex structure is needed, only the sheathed steel wire arranged in a coil, so that the structure is also simple.

[0060] Preferably, the part of the sheathed steel wire 5 arranged in at least one coil is located in the stand 2, that is, the coil of the sheathed steel wire 5 is located in the stand 2. Such an arrangement enables the part of the sheathed steel wire 5 arranged in a coil to be always in the stand 2 during the up and down movement of the stand 2 relative to the main support 1, thereby avoiding the possibility of being interfered by other components to the greatest extent, so that the coil of the sheathed steel wire 5 always exists, and the stability of the folding function of the present application is ensured.

[0061] In other embodiments, the loops of the sheathed steel wire 5 can also be formed in other locations, such as within the main support 1, or partially within the upright 2 and partially within the main support 1.

[0062] Preferably, a looped member can be provided within the upright 2 or the main support 1 or between the upright 2 and the main support 1, and the first steel wire 51 is looped at least once around the looped member. In this way, the loops of the sheathed steel wire 5 are always present, thereby ensuring that the stroke required to pull the upper end of the first steel wire 51 to unlock the locking device is always present, regardless of the height of the upright 2 and the handlebar 3 relative to the main support 1, and the folding function of the scooter is further ensured.

[0063] In this embodiment, the lower end of the first steel wire 51 is connected to the locking device through the first linkage device and the second linkage device. In other embodiments, the first linkage device and the second linkage device can not be provided, and the lower end of the first steel wire 51 is directly connected to the locking member 61. The upper end of the first steel wire 51 is pulled to pull the lower end of the first steel wire 51 to move the locking member 61 to disengage the locking portion 62 from the cooperating portion 41, thereby unlocking the locking device. Because the first sheathed steel wire described above is used, no matter what height the column 2 and the handle 3 are relative to the front support 11, as long as the upper end of the first steel wire 51 is pulled by a certain distance, the lower end of the first steel wire 51 moves by the same distance. That is, no matter what height the column 2 and the handle 3 are relative to the front support 11, when the upper end of the first steel wire 51 is pulled to move by the same distance, the distance that the locking member 61 moves is also equal. Therefore, no matter what height the column 2 and the handle 3 are relative to the front support 11, the locking device can be unlocked by pulling the first steel wire 51. Alternatively, the second linkage device is not provided, and the lower end of the first steel wire 51 is directly connected to the other end of the flexible cable 72. Similarly, no matter what height the column 2 and the handle 3 are relative to the front support 11, when the upper end of the first steel wire 51 is pulled to move, the distance that the other end of the flexible cable 72 is pulled is equal. Therefore, no matter what height the column 2 and the handle 3 are relative to the front support 11, the locking device can be unlocked by pulling the first steel wire 51. Alternatively, the second linkage device is not provided, and the first linkage device is only provided with the pulley 71. The lower end of the first steel wire 51 is connected to the main support 1 after passing through the pulley 71 (specifically, connected to the bridging member 122 of the main support). Therefore, the first steel wire 51 is equivalent to integrating the function of the flexible cable 72. When the upper end of the first steel wire 51 is pulled, the pulley 71 and the locking member 61 can also be pulled to move. The pulley 71 is still a movable pulley 71 mode. At the same time, the purpose of connecting the lower end of the first steel wire 51 to the locking device is achieved. The purpose of unlocking the locking device by pulling the first steel wire 51 through the unlocking device 8 is also achieved. In this connection mode, because the first sheathed steel wire described above is used, no matter what height the column 2 and the handle 3 are relative to the front support 11, when the upper end of the first steel wire 51 is pulled to move by the same distance, the distance that the first steel wire 51 and the pulley 71 are arranged to move is also equal. Therefore, the locking device can be unlocked.

[0064] In another embodiment (not shown), the first linkage device can also be provided as a second steel wire. One end of the second steel wire is connected to the locking member 61, and the other end is connected to the lower end of the first steel wire or the second linkage device. Therefore, when the lower end of the first steel wire 51 moves or the lower end of the first steel wire 51 pulls the second linkage device to move, the locking member 61 can be pulled to move through the second steel wire to disengage the locking portion 62 from the cooperating portion 41, thereby unlocking the locking device.

[0065] In another embodiment, the second linkage device can be provided with only a linkage member movably connected to the front support 11 in the up-down direction, the lower end of the first steel wire 51 being connected to the linkage member, and the other end of the flexible cable 72 or the second steel wire extending into the front support 11 and being connected to the linkage member; or, the second linkage device can be provided with a linkage member 78 movably located outside the main support 1 and in the sleeve connector 121, and a through hole being provided in the side wall of the front support 11, the lower end of the first steel wire 51 extending through the through hole and being connected to the linkage member 78, the first linkage device being connected to the linkage member, i.e. the other end of the flexible cable 72 or the second steel wire extending into the sleeve connector 121 and being connected to the linkage member 78. In this arrangement, the through hole can be provided below the linkage member 78, as shown in Figure 14 , so that when the upper end of the first steel wire 51 is pulled, the linkage member 78 is pulled downward by the lower end of the first steel wire 51 (as shown by the arrow in Figure 14 ), or the through hole can be provided above the linkage member, as shown in Figure 15 , so that when the upper end of the first steel wire 51 is pulled, the linkage member 78 is pulled upward by the lower end of the first steel wire 51. Regardless of whether the linkage member 78 moves upward or downward, the other end of the flexible cable 72 or the second steel wire is moved (upward or downward), i.e. the locking member is moved, thereby unlocking the locking device. In the case where the second linkage device is provided with only the linkage member, the second elastic return device can not be provided, because when the pulling force on the first steel wire 51 is released, the first elastic return member 63 returns the locking member 61, and the linkage member 78 is returned through the flexible cable 72 or the second steel wire. Alternatively, the second linkage device can be provided with the linkage portion, i.e. the first linkage member 74 and the second linkage member 75, and the other end of the flexible cable or the second steel wire of the first linkage device being connected to the second linkage member 75. Alternatively, the second linkage device can be provided with the second linkage member 75 movably located outside the front support 11 and in the sleeve connector 121 and the driving member 73, the lower end of the first steel wire 51 being connected to the second linkage member 75 (a through hole being provided in the side wall of the front support 11, the lower end of the first steel wire 51 extending through the through hole and being connected to the second linkage member 75, the driving member 73 being driven and moved by the second linkage member 75 when the lower end of the first steel wire 51 pulls the second linkage member 75), and the other end of the flexible cable 72 or the second steel wire being connected to the driving member 73.

[0066] That is to say, the lower end of the first steel wire 51 can be directly connected to the locking device, can be connected to the locking device through a first linkage device, and can be connected to the locking device through a first linkage device and a second linkage device. Regardless of the arrangement of the first linkage device and the second linkage device, as long as the sheath steel wire 5 is arranged as described above, the lower end of the first steel wire can move by a distance corresponding to the distance by which the upper end of the first steel wire is pulled, regardless of the height of the column 2 relative to the handlebar 3 at the front support 11, so that the locking device can be unlocked.

[0067] In other embodiments, the locking device can also be arranged in other known and feasible structures. The specific structure of the locking device is not the point of the present application, and any structure that can be unlocked by pulling the lower end of the first steel wire 51 is feasible.

[0068] In other embodiments, the unlocking device can also be any known and feasible structure, and can be arranged on the handlebar 3. The connection between the upper end of the first steel wire 51 and the unlocking device can also be any known and feasible structure. Since it is not the point of the present application, it will not be described here. Because the unlocking device is arranged on the column 2 or the handlebar 3, it is not necessary to bend down or squat to operate when unlocking. It is also not necessary to hold the column or handlebar with one hand while unlocking with the other hand. Because some scooters directly arrange the unlocking device at the locking device, i.e., the unlocking device is arranged relatively low, it is necessary to bend down or squat to operate. In addition, in order to avoid injury caused by the front support and the column falling down during unlocking, it is necessary to hold the column or handlebar with one hand while unlocking with the other hand, which is very inconvenient and troublesome.

[0069] In the present embodiment, preferably, the operating member 82 includes a body 821 arranged on the column 2 and two clamping portions 822 respectively extending to the left and right sides of the body 821, and the left and right clamping portions 822 are respectively provided with clamping grooves 823. The handlebar 3 is arranged to be rotatable downward on the left and right sides. When folding the scooter of the present application, the left and right sides of the handlebar 3 can be rotated downward, and the left and right sides of the handlebar 3 after being rotated downward are at least partially clamped into the clamping grooves 823 on the left and right sides. In this way, the size of the scooter of the present application after being folded can be reduced, and the left and right sides of the handlebar after being folded can be prevented from shaking, thereby facilitating transportation and packaging operations.

[0070] The specific structure of the handlebar 3 and its connection with the column 2 are not the points of the present application, and can be any known and feasible structure, so they will not be described here.

[0071] The scooter of the present application also includes a front wheel 9 arranged on the lower side of the main support 1, a rear wheel 10 arranged on the lower side of the pedal 4, and the front wheel 9 is arranged on the lower side of the front support 11.

[0072] In the embodiment, the adjusting device is arranged between the column 2 and the main support 1 for adjusting the relative height of the two, in the embodiment, the adjusting device comprises an adjusting seat 21 fixedly connected to the column 2, a positioning member 22 movably connected to the adjusting seat 21, an elastic member 23 arranged between the adjusting seat 21 and the positioning member 22 or arranged between the positioning member 22 and the column 2, a through hole arranged on the side wall of the column 2 and corresponding to the position of the positioning member 22, and a plurality of positioning holes 13 arranged on the side wall of the main support 1 in an up-down interval, when the through hole corresponds to one of the positioning holes 13, one end of the elastic member 23 passes through the through hole and then extends into the positioning hole 13 under the action of the elastic member 23, or one end of the elastic member 23 passes through the through hole and the positioning hole 13 and then protrudes out of the main support 1, so as to position the column 2 at the relative height.

[0073] The adjusting seat 21 is provided with a containing groove 211 opening towards the through hole, and the other end of the positioning member 22 is movably arranged in the containing groove 211. The elastic member 23 is a compression spring arranged between the side wall corresponding to the end of the positioning member 22 away from the through hole and the containing groove 611.

[0074] When the height of the handlebar 3 is to be adjusted, the positioning member 22 can be pressed inward, so that the positioning member 22 moves into the containing groove 211 of the adjusting seat 21 and is separated from the positioning hole 13, at this time, the column 2 can move up and down relative to the main support 1. In this way, the height adjustment operation of the handlebar 3 is realized.

[0075] Preferably, the adjusting seat 21 and the surrounding member are arranged as one component, that is, the adjusting seat 21 is the surrounding member, and the surrounding member is the adjusting seat 21, and the sheath steel wire 5 surrounds the outside of the surrounding member. In this way, the cost is reduced, and the structure is more compact, and the arrangement of components is more convenient.

[0076] In the embodiment, in order to make the assembly more convenient, one assembly seat 20 comprises a abutting part 201 abutting against the lower end of the column 2 and an extension part 202 extending upward from the abutting part and extending into the column 2, and the extension part 202 is fixedly connected to the column 2. The extension part comprises at least two opposite side walls, and the two ends of the adjusting seat 21 are integrally formed with the two opposite side walls, that is, the two ends of the surrounding member are integrally formed with the two opposite side walls. In this way, the assembly is more convenient.

[0077] In other embodiments, the assembly seat can not be arranged, and the surrounding member (adjusting seat 21) is fixedly connected to the column 2, for example, the upper side or the lower side of the surrounding member (adjusting seat 21) is fixedly connected to the column 2, which can be rivet or bolt fixed, or other known feasible ways.

[0078] The column 2 is also provided with a second connecting seat 24, which is located below the first connecting seat 81, and the upper end of the sheath 52 is connected to the second connecting seat 24.

[0079] Combination such as Figure 16 As shown, in this embodiment, the upper end of the sheath 52 of the sheathed steel wire 5 is T-shaped (as shown in 521 in the figure). The second connecting seat 24 is provided with a first through-connecting groove 25 that runs vertically through the wire. The first through-connecting groove 25 includes a first groove 251, a second groove 252, and a third groove 253 that are arranged vertically and connected. The first through-connecting groove 25 is configured such that the horizontal portion of the upper T-shaped end 521 of the sheathed steel wire 5 is placed in the second groove 252 and cannot enter the first groove 251 or the third groove 253. The first groove 251 allows the upper end of the first steel wire 51 to pass through and connect with the first connecting seat 81, and the vertical portion of the upper T-shaped end 521 of the sheathed steel wire 5 passes through the third groove 253. During assembly, the upper end of the T-shaped sheath 52 of the sheathed steel wire 5 and the first steel wire 51 are inserted from the opening side of the first through-connecting groove 25.

[0080] The second connecting seat 24 is fixedly connected to the column 2. The opening side of the first connecting groove 25 abuts against the inner wall of the column 2, so that the upper end of the sheath 52 assembled on the second connecting seat 24 will not detach from the second connecting seat 24.

[0081] The main support is provided with a third connecting seat 14, and the lower end of the sheath 52 is connected to the third connecting seat 14. The third connecting seat 14 is located below the second connecting seat 24.

[0082] In this embodiment, the lower end of the sheath 52 of the sheathed steel wire 5 is inverted T-shaped (e.g., Figure 5 As shown in Figure 522), similarly, the third connecting seat 14 is provided with a second through connecting groove 15 that runs vertically through the body. The second through connecting groove 15 includes a fourth groove 151, a fifth groove 152, and a sixth groove 153 that are arranged vertically and connected to each other. Figure 9 As shown), the second connecting groove 15 is configured such that the horizontal portion of the lower T-shaped end 522 of the sheathed steel wire 5 is placed in the fifth groove 152 and cannot enter the upper fourth groove 151 or the lower sixth groove 153. The vertical portion of the lower T-shaped end 522 of the sheath 52 passes through the fourth groove 151, and the sixth groove 153 allows the lower end of the first steel wire 51 to pass through. During assembly, the lower end of the T-shaped sheath 52 of the sheathed steel wire 5 and the first steel wire 51 are inserted from the opening side of the second connecting groove 15.

[0083] The third connecting seat 14 is placed in the main support, the side wall of the main support is provided with a containing hole, the height of the containing hole is lower than the height of the third connecting seat 14; a fixing member 16 is placed in the containing hole at least partially adaptively, the fixing member 16 is fixedly connected with the third connecting seat 14. Because the fixing member 16 is placed in the containing hole at least partially adaptively, the fixing member 16 cannot move up and down and left and right relative to the front support 11, and because the height of the third connecting seat 14 placed in the front support 11 is higher than the containing hole, after the fixing member 16 and the third connecting seat 14 are fixedly connected, the third connecting seat 14 cannot come out of the containing hole, so that the purpose of fixedly connecting the third connecting seat 14 and the main support 1 is achieved.

[0084] In the case that the lower end of the first steel wire is connected (connected with the locking member of the locking device) with the locking device through the first linkage device and the second linkage device, the main support 1 is provided with a fourth connecting seat 17 which can move up and down relative to the main support 1, the lower end of the first steel wire 51 is connected with the fourth connecting seat 17, and the second linkage device is connected with the fourth connecting seat 17.

[0085] The third connecting seat and the fourth connecting seat 17 are both connected with the front support, and correspondingly, the containing hole is also provided on the side wall of the front support 11. By providing the containing hole, the fixing member and the third connecting seat as described above, the assembly of the T-shaped lower end 522 of the sheath steel wire 5, the first steel wire 51, the third connecting seat 14 and the stand 2, the front support 11 and the first linkage member 74 can be facilitated. Specifically, after the fourth connecting seat 17 and the first linkage member 74 are assembled, they are placed in the front support 11, then the stand 2 and the front support 11 are assembled after the T-shaped lower end 522 of the sheath 52 and the third connecting member are connected, at this time, the fourth connecting seat can be pulled up through the containing hole, the lower end of the first steel wire 51 and the fourth connecting seat are assembled, and then the fixing member 16 and the third connecting seat are fixedly connected. If the containing hole and the fixing member 16 are not provided, but the lower end of the sheath, the lower end of the first steel wire, the third connecting seat, the fourth connecting seat and the first linkage member are all assembled, and then the whole assembly is placed in the front support from top to bottom, it is not necessarily guaranteed that the sheath and the lower end of the first steel wire will not come out of the third connecting seat and the fourth connecting seat during the process of placing, if they come out, the assembly needs to be repeated, thus the assembly efficiency is delayed.

[0086] The fourth connecting seat 17 is connected with the first linkage 74 of the second linkage device through an intermediate piece 18. In the embodiment, the fourth connecting seat 17 is provided with a T-shaped connecting hole 171 in the middle, and the intermediate piece 18 is correspondingly in T shape. The vertical part of the T-shaped intermediate piece 18 passes through the T-shaped connecting hole 171 from top to bottom and is connected with the second linkage device, specifically, the vertical part of the T-shaped intermediate piece 18 passes through the T-shaped connecting hole 171 from top to bottom and then penetrates into the upper end of the first linkage 74 and is fixedly connected with the first linkage 74. In other embodiments, the lower end of the fourth connecting seat 17 can be directly connected with the first linkage 74.

[0087] Preferably, the third connecting seat 14 comprises a main body 141 and a guide part 142 extending downward from one side of the main body 141, and a second guide block 1421 and a second guide groove 170 are arranged between the guide part 142 and the fourth connecting seat 17. When the upper end of the first steel wire 51 is pulled, the fourth connecting seat 17 is also pulled upward by the lower end of the first steel wire 51, and under the cooperation of the second guide block 1421 and the second guide groove 170, the movement of the fourth connecting seat 17 is smoother. The second through connecting groove 15 is arranged on the main body 141.

[0088] In other embodiments, the upper and lower ends of the sheath 52 can also be connected with the stand 2 and the main support 1 respectively by other known feasible ways.

[0089] In the above description of the up, down, left, right, front and back directions, the directions are defined based on the use state that the child stands on the pedal 4 and holds the handlebar 3, specifically, the front wheel 9 is taken as the front side, the rear wheel 10 is taken as the rear side, the handlebar 3 is taken as the upper side, the front wheel 9 and the rear wheel 10 are taken as the lower side, and the two sides of the handlebar 3 are taken as the left and right sides. It should be understood that when the viewing angle changes, the directions also change.
