[0002] Tire changers are devices used to install and remove tires from various vehicles, including cars, motorcycles, and heavy trucks. They are essential equipment for auto repair shops and dealerships. Currently, tire changers are evolving towards multi-functionality to accommodate a wider range of tire types and sizes.

[0003] Existing tire changers typically have a bird head mounted on the top of the column, and an auxiliary column on one side for mounting the tire clamp and auxiliary arm. To ensure sufficient strength of the machine and stability of the bird head when handling tires of different sizes and types, both the column and the auxiliary column need to be designed to be relatively large. Furthermore, to prevent interference between the bird head and the tire clamp, a certain distance must be maintained between the column and the auxiliary column.

[0004] In summary, this results in a large size and weight of the entire device, which in turn leads to relatively high manufacturing and logistics costs.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A tire changer with double-sided sliding columns, combined with Figures 1-8As shown, the device includes a housing 1 and a column 2. The bottom end of the column 2 is fixed to the housing 1. A vertical first slide rail 31 is fixed on one side of the column 2. A first slide block 32 is slidably provided on the first slide rail 31. A tire removal hook assembly 4 is provided on the first slide block 32. A first driver 33 is provided on the side of the column 2 away from the housing 1. The first driver 33 drives the first slide block 32 to slide along the first slide rail 31. A vertical second slide rail 34 is fixed on the other side of the column 2. A second slide block 35 is slidably provided on the second slide rail 34. An upper pressure plate assembly 5 is provided on the second slide block 35. A second driver 36 is provided on the side of the column 2 away from the housing 1. The second driver 36 drives the second slide block 35 to slide along the second slide rail 34. This application provides a first slide rail 31 and a second slide rail 34 on both sides of the column 2, and a first slide block 32 and a second slide block 35 on the first slide rail 31 and the second slide rail 34 respectively. The first slide block 32 and the tire removal hook assembly 4 are driven to move together by the first driver 33, and the second slide block 35 and the upper pressure plate assembly 5 are driven to move together by the second driver 36. This allows the tire removal hook assembly 4 and the upper pressure plate assembly 5 to be distributed on both sides of the column 2, avoiding mutual interference between the tire removal hook assembly 4 and the upper pressure plate assembly 5. Furthermore, the first slide rail 31, the second slide rail 34 and the column 2 are integrated into one unit, which not only eliminates the auxiliary column, but also strengthens the column. In summary, the layout and structure itself can reduce the size and weight of the entire device, thereby reducing manufacturing and logistics costs.

[0021] Preferably, a third slide block 37 is slidably provided on the second slide rail 34, and a lower pressure platen assembly 6 is provided on the third slide block 37. A third actuator 38 is provided on the side of the column 2 away from the housing 1, and the third actuator 38 drives the third slide block 37 to slide along the second slide rail 34. By providing the second slide block 35 and the third slide block 37 on the second slide rail 34, the upper pressure platen assembly 5 and the lower pressure platen assembly 6 are arranged vertically on one side of the column 2 to cooperate in completing the tire installation and removal.

[0022] Preferably, the angle between the slide plane of the first slide 31 and the slide plane of the second slide 34 is less than 180° and the angle points towards the housing 1, so that both the upper pressure plate assembly 5 and the lower pressure plate assembly 6 can be easily moved onto the tire for operation along with the tire removal hook assembly 4.

[0023] Preferably, the angle between the slide plane of the first slide 31 and the slide plane of the second slide 34 is greater than or equal to 45° and less than or equal to 60°. In this embodiment, the angle is selected as 60°.

[0024] Preferably, the first actuator 33, the second actuator 36, and the third actuator 38 are arranged side by side on the side of the column 2 away from the housing 1. In this embodiment, the first actuator 33, the second actuator 36, and the third actuator 38 are cylinders.

[0025] Specifically, the column 2 is a square column, and the first driver 33, the second driver 36, and the third driver 38 are arranged side by side along the back side of the column 2 (the side of the column 2 away from the housing 1), making the overall structure more compact and convenient for installation and debugging.

[0026] Preferably, a first reinforcing connecting frame 391 is added between the first slide rail 31 and the column 2. The first reinforcing connecting frame 391 is used to connect the column 2 and the first slide rail 31 and to enhance the rigidity of the column 2 and the first slide rail 31. A second reinforcing connecting frame 392 is added between the second slide rail 34 and the column 2. The second reinforcing connecting frame 392 is used to connect the column 2 and the second slide rail 34 and to enhance the rigidity of the column 2 and the second slide rail 34.

[0027] Specifically, the first reinforcing connecting frame 391 includes a first reinforcing connecting frame body 3911 and several reinforcing plates 3912. The cross-section of the first reinforcing connecting frame body 3911 is trapezoidal. The first reinforcing connecting frame body 3911 is fixed to the side of the column 2 by welding. The first slide rail 31 is fixed to the first reinforcing connecting frame body 3911 by screws. The several reinforcing plates 3912 are fixed by welding and are spaced apart along the length of the first reinforcing connecting frame body 3911. The first reinforcing connecting frame 391 strengthens the rigidity of the column 2 and the first slide rail 31 and ensures the tilt angle of the first slide rail 31. Similarly, the second reinforcing connecting frame 392 has the same structure, which will not be described in detail here.

[0028] Preferably, the third driver 38 is located between the first driver 33 and the second driver 36; A first mounting part 321 is fixedly provided on the first slide block 32. The first mounting part 321 extends toward the side of the column 2 away from the housing 1 and is connected to the output shaft of the first driver 33. A second mounting part 351 is fixedly provided on the second slide 35. The second mounting part 351 extends toward the side of the column 2 away from the housing 1 and is connected to the output shaft of the second driver 36. A third mounting portion 371 is fixed on the third slide 37. The third mounting portion 371 extends toward the side of the column 2 away from the housing 1 and passes between the column 2 and the output shaft of the second driver 36. The third mounting portion 371 is connected to the output end of the third driver 38. The connection is achieved through the first mounting portion 321, the second mounting portion 351, and the third mounting portion 371, and interference between the second slide 35 and the third slide 37 can be avoided.

[0029] Specifically, a first mounting seat 322 for mounting the tire removal hook assembly 4 is fixedly welded onto the first slide 32, and a first mounting portion 321 extends from the first mounting seat 322, being a part of the first mounting seat 322. A second mounting seat 352 for mounting the upper pressure plate assembly 5 is fixedly welded onto the second slide 35, and the second mounting portion 351 is welded to the upper end of the second slide 35. A third mounting seat 372 for mounting the lower pressure plate assembly 6 is fixedly welded onto the third slide 37, and the third mounting seat 372 is welded to the upper end of the third slide 37.

[0030] Specifically, in combination Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, the tire removal hook assembly 4 includes a tire removal hook 41, a tire removal head 42, and a tire removal hook mounting base 43. The tire removal hook mounting base 43 is mounted on a first mounting base 322. The tire removal hook mounting base 43 has a guide channel, which includes a first working cavity 431 with a cylindrical inner wall, allowing the tire removal head 42 to move along its axial direction and rotate freely around its own axis. The tire removal head 42 has a limiting boss 423, and the opening end of the guide channel has a corresponding limiting boss. A limiting groove 434 is adapted to 423; a tire removal hook 41 is connected to one end of the disassembly head 42; when the disassembly head 42 is located in the axial high position of the guide channel, the limiting boss 423 is embedded in the limiting groove 434, restricting the circumferential rotation of the disassembly head 42 and the tire removal hook 41; when the disassembly head 42 is pushed to the axial low position of the guide channel, the limiting boss 423 disengages from the limiting groove 434, allowing the disassembly head 42 and the tire removal hook 41 to rotate around their axis, thereby achieving displacement.

[0031] Specifically, in the initial state, the tire removal head 42 is located at the axial high position of the guide channel within the tire removal hook mounting base 43. At this time, the limiting boss 423 on the tire removal head 42 is embedded in the limiting groove 434 at the opening end of the guide channel. Since the limiting boss 423 and the limiting groove 434 cooperate with each other in the circumferential direction, the rotation of the tire removal head 42 around its axis is restricted, thereby keeping the connected tire removal hook 41 in a fixed position and preventing it from rotating, which is suitable for tire removal operations that require stable force application.

[0032] When it is necessary to change the angular position of the tire removal hook 41, the removal head 42 is pushed axially, causing it to move towards the axially lower position of the guide channel. As the removal head 42 descends, the limiting boss 423 gradually disengages from the limiting groove 434. Once completely disengaged, the limiting boss 423 is no longer circumferentially constrained by the limiting groove 434, and since the guide channel is a cylindrical surface, it does not impose circumferential restrictions on the removal head 42. Therefore, the removal head 42 can rotate freely around its own axis. Since the tire removal hook 41 is connected to one end of the removal head 42, the two rotate synchronously, thereby realizing the rotational displacement of the tire removal hook 41.

[0033] Specifically, by dividing the guide channel into a first working cavity 431, a second working cavity 432, and a third working cavity 433 with successively decreasing inner diameters, and setting a sufficiently large inner diameter (greater than the outer circle diameter of the limiting boss 423) in the first working cavity 431, the limiting boss 423 can rotate freely inside it after disengaging from the limiting groove 434, thereby ensuring smooth and interference-free rotational displacement of the disassembly head 42 and the connected tire removal hook 41; at the same time, the multi-stage stepped cavity structure provides a clear axial high and low position positioning reference for the disassembly head 42, taking into account both rotational freedom and circumferential locking reliability, and improving operational flexibility and usage stability.

[0034] Specifically, the disassembly / assembly head 42 adopts an integrally formed concentric double-cylinder structure. The diameter of the first working end 421 is larger than the diameter of the second working end 422. The diameter of the second working end 422 matches the inner diameter of the third working cavity 433, allowing it to mate radially with the inner wall of the third working cavity 433 and slide axially. Combined with the smooth annular groove at the transition between the second working end 422 and the first working end 421, and the stop ring 424 embedded therein, a balance between compact structure and reliable movement is achieved. The inner hole of the stop ring 424 is divided into a first diameter section 4241 and a second diameter section 4242, matching the inner diameters of the first working cavity 431 and the second working cavity 432. This allows it to slide smoothly axially within the guide channel and achieve precise axial positioning through mating with different working cavities. Meanwhile, the stop ring 424 and the disassembly head 42 are not fixedly connected in the circumferential direction, ensuring that the disassembly head rotates without obstruction. This ensures axial positioning accuracy while effectively supporting the rotational displacement function of the tire hook, improving the overall stability, durability and ease of use of the operation.

[0035] Specifically, such as Figure 10 and Figure 11 The limiting boss 423 adopts a hexagonal prism structure and is integrally formed with the disassembly head 42. The limiting groove 434 is an internal hexagonal through hole structure located at the opening end of the guide channel. Its hexagonal inner contour and the hexagonal limiting boss 423 on the disassembly head 42 form a shape-fitting pair to achieve circumferential locking in the axial high position state. Multiple cylindrical guide holes are provided around the groove to assist in positioning and assembly. At the same time, the first limiting step structure set at the transition between the opening end of the guide channel inner wall and the first working cavity 431 mates with the end face of the first diameter section 4241 of the stop ring 424 to form a clear and reliable axial high position positioning reference. This design organically combines circumferential locking and axial limiting functions, with a compact structure and precise positioning. It not only prevents the disassembly head from accidentally coming out, but also ensures the secure locking of the rotary displacement mechanism in the high position state.

[0036] Specifically, by setting a second limiting step structure at the transition between the first working cavity 431 and the second working cavity 432 on the inner wall of the guide channel, and cooperating with the other end face of the first diameter section 4241 of the stop ring 424, precise and stable axial limiting can be achieved when the disassembly head 42 moves axially to the low position. This limiting method effectively prevents the disassembly head from descending excessively or shaking, ensuring its positional reliability in the low-position displacement state; at the same time, combined with the high-position limiting structure, a bidirectional axial positioning is formed, so that the disassembly head has a clear mechanical stop in both high and low working positions, which not only ensures the smoothness of the rotation displacement operation, but also improves the stability and durability of the overall structure, which is conducive to improving the efficiency and safety of tire removal operations.

[0037] Specifically, a spring is installed inside the second working chamber 432. The lower end of the spring abuts against the bottom of the second working chamber 432, and the upper end abuts against the lower end face of the stop ring 424. When the disassembly head 42 is pushed to the low position, the spring is compressed. After the external force is released, it pushes the stop ring 424 and the disassembly head 42 to reset upward, so that the limiting boss 423 re-embeds into the limiting groove 434, restoring the axial high-position locking state. This design realizes automatic reset and circumferential locking after the tire hook is rotated and displaced, significantly improving the ease of operation.

[0038] Specifically, in combination Figure 1 , Figures 12-18 As shown, the upper pressure placenta assembly 5 includes an operating arm 51 and an operating arm locking mechanism 52. The operating arm 51 is rotatably connected to the second mounting base 352 via a mounting base connecting shaft 53 fixed thereon. The operating arm locking mechanism 52 is disposed on the second mounting base 352 and is used to lock the operating arm 51 to the second mounting base 352 to prevent rotation.

[0039] Specifically, the operating arm locking mechanism 52 includes: a locking mounting base 521, a locking pin 522, a spring 523, a handle 524, and a pin sleeve 525; like Figure 13 As shown, the pin sleeve 525 is welded to the operating arm 51, the locking mounting seat 521 is set on the second mounting seat 352, the locking pin 522 is set on the locking mounting seat 521, the spring 523 is sleeved on the locking pin 522, and the handle 524 can drive the locking pin 522 to disengage from the pin sleeve 525. As the operating arm 51 approaches the second mounting base 352 by rotating, the end of the locking pin 522 away from the handle 524 slides along the outer surface of the pin sleeve 525, causing the spring 523 to be gradually compressed. When the locking pin 522 slides to the pin hole of the pin sleeve 525, the spring 523 returns to its original position, driving the locking pin 522 to insert into the pin sleeve 525.

[0040] The locking pin 522 is disengaged from the sleeve 525 by the handle 524, thus unlocking the operating arm 51; when a locking operation is required, the operating arm 51 is rotated (e.g., ...). Figure 14 As shown, it rotates around the mounting base connecting shaft 53 during rotation. Figure 14 (In the locked state), it moves closer to the second mounting base 352. During this process, the locking pin 522 slides along the outer surface of the pin sleeve 525, causing the spring 523 to be gradually compressed. When the locking pin 522 slides directly above the pin hole of the pin sleeve 525, the spring 523 is no longer compressed and returns to its initial state. Thus, the locking pin 522 is driven to insert into the pin sleeve 525 by the elastic force, and the locking function can be achieved without alignment, thus improving the operating efficiency.

[0041] Specifically, such as Figure 18 As shown, the pin sleeve 525 is frustum-shaped. When a locking operation is required, the operating arm 51 is rotated, the bottom of the locking pin 522 contacts the bottom of the pin sleeve 525, slides along the outer surface of the pin sleeve 525, the bottom of the locking pin 522 rises, the spring 523 is compressed, until the locking pin 522 slides directly above the pin hole of the pin sleeve 525.

[0042] Specifically, such as Figure 15 As shown, the locking mounting base 521 includes a fixed support 5211 and a rotating support 5212 that is rotatably connected to the fixed support 5211 via a rotating shaft; The handle 524 is fixed on the rotating support 5212 (welded or integrally formed). When the handle 524 is rotated, the handle 524 drives the locking pin 522 to move vertically upward through the rotating support 5212, so as to disengage from the pin sleeve 525.

[0043] Specifically, such as Figure 15 As shown, it also includes a guide sleeve 526, which is vertically welded and fixed to the second mounting base 352, as shown. Figure 17 As shown, a stop portion 5261 is provided at the end of the guide sleeve 526 away from the second mounting base 352; The locking pin 522 is located inside the guide sleeve 526. The locking pin 522 is a stepped shaft. The large diameter end of the stepped shaft is close to the operating arm 51. One end of the spring 523 abuts against the stop part 5261, and the other end abuts against the diameter change part of the stepped shaft.

[0044] Press down the handle 524, compress the spring 523, and rotate the support 5212 to drive the locking pin 522 to move vertically upward to disengage from the sleeve 525 (after disengagement, continue to press down the handle 524 and rotate the operating arm 51 until the sleeve 525 is far away from the locking pin 522 before releasing the handle).

[0045] Specifically, such as Figure 17As shown, the top of the locking pin 522 is provided with a limiting pin hole 5221 perpendicular to the axis of the locking pin 522. A limiting pin 527 is provided in the limiting pin hole 5221. The top of the rotating support 5212 is provided with a through hole. After the locking pin 522 passes through the through hole, it is connected to the limiting pin 527 through the limiting pin hole 5221, so as to prevent the locking pin 522 from disengaging from the rotating support 5212 through the limiting pin 527.

[0046] Specifically, such as Figure 16 As shown, spacers 528 are fitted at both ends of the limiting pin 527 (the spacers 528 are prevented from disengaging from the limiting pin 527 by snap rings), and a hexagonal sleeve 529 is fitted at the top of the locking pin 522 (the hexagonal sleeve 529 has a hole that allows the limiting pin 527 to pass through). By setting spacers 528 and hexagonal sleeves 529, the locking structure is reinforced.

[0047] Preferably, the side of the column 2 is provided with an auxiliary arm 7 for assisting in tire pressing during tire loading. The auxiliary arm 7 is located above the second slide rail 34, and the end of the auxiliary arm 7 is provided with a tire pressing block driver 71, which drives the tire pressing block 72 to move vertically.

[0048] Preferably, the housing 1 is provided with a tire quick-locking device 8 for quickly locking the tire, and the side of the housing 1 is provided with a large shovel assembly 9 for shoveling the tire.

[0049] Specifically, in combination Figure 1 , Figure 2 , Figure 19 , Figure 20 and Figure 21 As shown, the tire quick-locking device 8 includes: a disc body 83, a fixed shaft 84, and a shaft seat 85 connected in sequence; The top end of the fixed shaft 84 is provided with an opening and a central hole is formed along the axial direction. Multiple sets of coaxial positioning through holes 841 are provided at intervals in the central hole. Positioning through holes 841 can selectively pass through positioning pins 86. The center of the bearing seat 85 is provided with a cavity for the fixed shaft 84 to slide up and down, and a limit hole 851 is correspondingly provided on the bearing seat 85. The limit hole 851 can be aligned with any set of positioning through holes 841 and locked with the positioning pin 86.

[0050] When the height of the disc 83 needs to be adjusted, the fixed shaft 84 is moved to the desired position, aligning the limiting through hole 851 on the shaft seat 85 with a set of positioning through holes 841 in the center hole of the fixed shaft 84. Then, the positioning pin 86 is inserted through both, achieving the lifting, positioning, and locking of the fixed shaft 84. By selecting different positioning through holes 841 at different height positions for engagement, multi-level adjustment of the lifting seat height can be achieved, thus meeting the different needs of upright or reverse-mounted wheel hubs during disassembly and assembly.

[0051] Specifically, the tire quick-locking device 8 also includes a lead screw assembly 81. The disc body 83 and the fixed shaft 84 are coaxially provided with radial mounting grooves for the lead screw assembly 81 to be inserted. As a key locking component in tire removal operations, the reliable cooperation between the lead screw assembly 81 and the lifting seat formed by the disc body 83, the fixed shaft 84, and the axle seat 85 can further improve the concentricity and clamping stability when the tire is fixed, effectively reducing the risk of wheel hub misalignment or slippage during disassembly and assembly.

[0052] Specifically, the lead screw assembly 81 includes a locking lead screw, which has a sliding section and a threaded section from bottom to top. Different types of locking cones 82 can be selectively fitted on the outside of the threaded section. The appropriate locking cone 82 can be flexibly replaced according to the size of the wheel hub center hole, thereby effectively expanding the compatibility range of the equipment with wheel hubs of different specifications.

[0053] Specifically, a quick-locking nut 811 is mounted on the threaded section. The quick-locking nut 811 has an internal thread 812 and a nut wrench 813. When the internal thread 812 is not engaged with the threaded section, rotating the nut wrench 813 allows the quick-locking nut 811 to move rapidly axially on the threaded section. This structure avoids the cumbersome process of repeatedly rotating multiple times to complete the adjustment in the traditional full-thread locking method, and greatly improves operating efficiency while ensuring clamping reliability.

[0054] Specifically, the quick-locking nut 811 is fitted onto the outside of the threaded section and has a notch for installing the internal thread 812, which is fixed to the notch by a retaining pin. Furthermore, the quick-locking nut 811 is rotatably connected to a nut wrench 813 via a rotating pin. The internal thread and the threaded section can be engaged or disengaged as needed, and the notch structure provides a structural basis for rapid axial sliding. In addition, the nut wrench is rotatably connected to the quick-locking nut via the rotating pin, ensuring that the wrench can swing flexibly during operation to adapt to different working angles, and preventing the wrench from shaking or falling off when not in use, thus improving convenience and safety.

[0055] Specifically, the disc 83 adopts an open plastic disc design with arc-shaped ports, which not only reduces the overall weight and manufacturing cost, but also facilitates the quick insertion or removal of the wheel hub during disassembly and assembly. A limiting shaft is bolted between the arc-shaped ports, maintaining the structural integrity of the disc and providing a reliable radial positioning reference for the locking cone. The locking cone 82 has a clearance groove that matches the limiting shaft, allowing it to move smoothly axially without interference after installation. Simultaneously, it is constrained circumferentially by the limiting shaft, effectively preventing rotational offset during locking and ensuring that the locking cone 82 is coaxially aligned with the center hole of the wheel hub. This mating structure significantly improves the stability and repeatability of the clamping process, avoiding wheel hub damage or clamping failure caused by misalignment of the locking cone 82, and further enhancing the reliability and ease of operation of the equipment in high-frequency, multi-specification tire disassembly and assembly operations.

[0056] Preferably, combined with Figure 1 , Figure 22 , Figure 23 and Figure 24 As shown, a tire lifter 10 for lifting tires is also provided on one side of the housing 1. The tire lifter 10 includes: a lifter column 101 fixed on one side of the housing 1, a lifter cylinder 102, a lifter transmission rod 103, and a lifting bracket 104 for carrying tires. One end of the lifter cylinder 102 is rotatably connected to the lifter column 101, and the other end is rotatably connected to the middle of the lifter transmission rod 103. One end of the lifter transmission rod 103 can rotate relative to the lifter column 101, and the other end is connected to the lifting bracket 104.

[0057] Specifically, a lift frame 107 is fixedly connected to one side of the housing 1 by screws, and the lift column 101 is fixedly connected to the lift frame 107 by screws. The lift frame 107 is also equipped with a tool box for storing tools and inflation pressure gauges, etc.

[0058] Specifically, when the lifting bracket 104 is subjected to an external force from bottom to top, the end of the lifting bracket 104 away from the lifting vehicle column 101 rotates upward. One end of the lifting cylinder 102 is rotatably connected to the lifting column 101 via a pin, and the other end of the lifting cylinder 102 is rotatably connected to the middle of the lifting transmission rod 103 via a pin. One end of the lifting transmission rod 103 can rotate relative to the lifting column 101, and the other end of the lifting transmission rod 103 is connected to the lifting bracket 104. In the tire lifting vehicle 10 of this application, the lifting cylinder 102 drives the lifting bracket 104 to rise and fall through the lifting transmission rod 103 to realize the vertical movement of the tire. When the lifting bracket 104 falls, if the bottom of the lifting bracket 104 touches the operator's feet, the lifting bracket 104 will be subjected to an upward reaction force and rotate, thereby preventing the lifting bracket 104 from continuously squeezing the operator's feet under the action of the lifting cylinder 102, and preventing crushing injury to the operator's feet during operation.

[0059] Specifically, such as Figure 23 and Figure 24 As shown, the lift vehicle transmission rod 103 includes a first lift vehicle transmission rod 1031 and a second lift vehicle transmission rod 1032 (the second lift vehicle transmission rod 1032 has a structural hole in the middle to avoid interference with the lift vehicle cylinder 102), and the lifting bracket 104 includes a bracket connecting plate 1041, as shown. Figure 24 As shown, the bracket connecting plate 1041 is provided with a through hole 1043 and an arc-shaped hole 1044 arranged around the axis of the through hole 1043; One end of the first lifting vehicle transmission rod 1031 is rotatably connected to the lifting vehicle column 101 via a pin, and the other end of the first lifting vehicle transmission rod 1031 is fixedly provided with a first connecting shaft 105. The first connecting shaft 105 is located in the through hole 1043, and the bracket connecting plate 1041 is rotatably connected to the first lifting vehicle transmission rod 1031 via the first connecting shaft 105. One end of the second lifting vehicle transmission rod 1032 is rotatably connected to the lifting vehicle column 101 via a pin, and the other end of the second lifting vehicle transmission rod 1032 is fixed with a second connecting shaft 106. The second connecting shaft 106 is located in the arc-shaped hole 1044. When the lifting bracket 104 is subjected to an upward reaction force, the second connecting shaft 106 slides along the arc-shaped hole 1044, causing the end of the lifting bracket 104 away from the lifting vehicle column 101 to rotate upward.

[0060] In practical applications, the first connecting shaft 105 and the second connecting shaft 106 can be round tubes. The bolt is inserted into one end of the round tube and the nut is screwed out from the other end. The bolt head and the nut play a limiting role to prevent the bracket connecting plate 1041 from separating from the first connecting shaft 105 and the second connecting shaft 106.

[0061] Specifically, such as Figure 23As shown, the lifting bracket 104 also includes a bracket support plate 1042. The bracket support plate 1042 includes a support base plate 1045 and a support baffle 1046. The support baffle 1046 is fixed on the bracket connecting plate 1041 (integrated or welded). The support baffle 1046 is located at one end of the support base plate 1045 near the lifting column 101. The end of the support base plate 1045 near the lifting column 101 is lower than the other end, so that the vertical tire placed in the lifting bracket 104 can maintain the tendency to roll towards the lifting column 101, so that when the lifting bracket 104 falls normally (i.e., without touching the operator's feet), the tire will not roll out of the lifting bracket 104.

[0062] Specifically, such as Figure 23 and Figure 24 As shown, the lifting bracket 104 also includes a bracket support frame 1047 welded and fixed to the bracket connecting plate 1041. The bracket support frame 1047 is located on the outer periphery of the bracket support plate 1042 and welded and fixed to the bracket support plate 1042, so that the tire can be locked in the bracket support frame 1047, further preventing the tire from rolling out of the lifting bracket 104.
