Walking positions 403 are arranged on two sides of the chassis 201, two directional rollers 401 are arranged on the walking positions 403 on two sides of the chassis 201, and each directional roller 401 corresponds to one walking position 403. For example, the chassis 201 is further provided with an adjusting position 404, and the universal roller 402 is arranged at the adjusting position 404. Thus, the frame 101 can be quickly moved by the two directional rollers 401 and the universal roller 402, and the moving direction of the frame 101 can be adjusted at any time according to actual needs.

In order to balance the stress of the walking member 203, in this embodiment, the two directional rollers 401 and the universal roller 402 are distributed in a "delta" shape or a triangular shape. And the axes of the two directional rollers 401 and the axis of the chassis 201 are on the same straight line. For example, the steering position 404 is adjacent to the axes of the two steering rollers 401. In this embodiment, the orientation indicator 404 has an equilateral triangular cross section. For example, the chassis 201 is integrally extended with an orientation adjusting bit 404. Thus, when an object is placed on the support member 102 or the support member 102 is used to support and lift the object, the gravity of the object is transmitted to the chassis 201, the chassis 201 distributes the gravity of the object to the two directional rollers 401 and the universal roller 402, at this time, the axes of the two directional rollers 401 and the axis of the chassis 201 are located on the same straight line so as to distribute the gravity of the object in a balanced manner, and because the axes of the two directional rollers 401 and the axis of the chassis 201 are located on the same straight line, the two directional rollers 401 can bear most of the gravity of the object, and meanwhile, the two directional rollers 401 can also play a role of stable support, so that the frame body 101 is stable when walking.

In this embodiment, the bottom plate 201 has a plate-like structure. For the purpose of enhancing strength, for example, the chassis 201 and the frame 202 are integrally formed. For another example, the chassis 201 and the frame 202 are integrally injection molded. For another example, the chassis 201 and the frame 202 are integrally cast steel. Since the chassis 201 is mainly stressed, in other embodiments, the chassis 201 and the frame 202 may be detachably connected to facilitate transportation and assembly of logistics.

Referring to fig. 8 and 10, in the present embodiment, the frame 202 has a semicircular cross section. For example, a telescopic space 206 is formed between the frame 202 and the chassis 201. For example, the telescoping piece 204 is located in the telescoping space 206. It can be understood that the frame 202 has a semicircular cross section to avoid the telescopic member 204, and a telescopic space 206 is formed, and the telescopic member 204 can be freely stretched and retracted in the telescopic space 206 without limitation. In this embodiment, the retractable member 204 is a pneumatic retractable cylinder, and the structure thereof is similar to the retractable structure of the lifting swivel chair. For example, the telescopic member 204 is provided with a control switch 405 to control the raising and lowering of the telescopic member 204 by the control switch 405.

To avoid the support member 102 from touching the frame 202 during the lowering process, for example, the minimum length of the telescopic member 204 is greater than the height of the frame 202. That is, when the telescopic member 204 is in the original non-extended state, the rotating portion 205 at the end of the telescopic member 204 is higher than the frame 202, and thus the design is such that after the telescopic member 204 is connected with the support member 102, the telescopic member 204 drives the support member 102 to move up and down, and a certain distance is always kept between the support member 102 and the frame 202, and this distance enables the support member 102 to be adjusted and swung up and down relative to the horizontal plane without touching the frame 202 when the telescopic member 204 is in the original non-extended state.

For example, a placing area 601 is formed between the two fixing blocks 304, and the two limiting rods 305 are erected on the placing area 601. For example, a preset width is formed between the two fixing blocks 304, and the length of the limiting rod 305 is greater than the preset width, so that the limiting rod 305 can be adjusted and installed. For example, the stopper 305 is detachably connected to the fixing block 304.

Referring to fig. 13, a schematic diagram of an embodiment of a fixing block 304 is shown, in order to accommodate various objects placed on a placing area 601 of a base plate 301, for example, the fixing block 304 has a triangular cross section. For example, the triangle is an equilateral triangle. For example, the fixing block 304 is provided with an adjusting channel 710. The adjusting channel 710 has a central symmetrical structure, and the axis of symmetry is the axis of the triangular fixing block 304. For example, the adjustment passage 710 has a first passage portion and a second passage portion that are centrosymmetric, and the first passage portion and the second passage portion are provided in communication. For example, the first channel portion includes a wider low-voltage region 711, a higher medium-voltage region 712, a narrower low-voltage region 713, a transition region 714, and a narrower high-voltage region 715.

For example, a wider low-pressure zone 711 is located at the bottom of the anchor block 304 near the placement area 601, i.e., at the bottom corner of an equilateral triangle. For example, a wider distance exists between the wider low-pressure area 711 of the first channel portion and the wider low-pressure area of the second channel portion, that is, after the two position-limiting rods 305 are erected on the placing area 601, a wider distance exists between the two position-limiting rods 305, but the position-limiting rods 305 are close to the placing area 601, so that the two position-limiting rods 305 can clamp a first object with a lower height and a larger width of the clamped portion, that is, the cross section area, when the two position-limiting rods 305 are arranged in the wider low-pressure area 711, that is, the height of the first object is lower than the distance between the position-limiting rods 305 and the bottom plate 301, and the width is smaller than the distance between the two.

For example, higher mid-press zone 712 is located at the bottom of fixed block 304, i.e., near the bottom corner of an equilateral triangle. For example, higher mid-voltage region 712 is higher than wider low-voltage region 711. For example, after the two position-limiting rods 305 are erected on the placing area 601, there is a wider distance between the higher middle pressure area 712 of the first channel portion and the higher middle pressure area of the second channel portion, that is, after the two position-limiting rods 305 are erected on the placing area 601, there is a wider distance between the two position-limiting rods 305, but the height of the position-limiting rods 305 from the placing area 601 is greater than the height of the position-limiting rods 305 from the placing area 601, so that the two position-limiting rods 305 can clamp a second object with a larger width and a higher height than the first object when being placed in the higher middle pressure area 712, wherein the larger width is a larger area of the cross section.

For example, the narrower low-pressure zone 713 is located in the mid-bottom region of the anchor block 304, i.e., near the axis of the equilateral triangle and near the base of the equilateral triangle. For example, the height of narrower low-voltage region 713 is between wider low-voltage region 711 and higher medium-voltage region 712. Since the narrower low-pressure region 713 is close to the axis of the equilateral triangle, and the distance between the narrower low-pressure region 713 of the first channel portion and the narrower low-pressure region 713 of the second channel portion is narrow, placing the two retaining bars 305 in the narrower low-pressure region 713 can clamp the clamped portion at a height that is between the wider low-pressure region 711 and the higher medium-pressure region 712, i.e., a third object having a smaller width, i.e., a smaller cross-sectional area.

For example, the transition zone 714 has a certain curvature, i.e., is formed by extending upward from the bottom corner of the equilateral triangle toward the axis of the equilateral triangle in a curved manner. For example, transition zone 714 is taller than higher intermediate pressure zone 712. For example, the distance between the transition zone 714 of the first channel portion and the transition zone of the second channel portion is narrow, so that the two position-limiting rods 305 can clamp the clamped portion of the fourth object with a height higher than the higher middle pressure zone 712 when being arranged in the transition zone 714, and the width, i.e., the cross-sectional area, of the fourth object is smaller than that of the third object. Moreover, since the transition region 714 has a certain curvature, the height and the cross-sectional area of the clamped portion of the fourth object have a certain range, i.e. there are many choices.

For example, the narrow high pressure zone 715 is located in the middle region of the fixed block 304, i.e., near the upper center of an equilateral triangle. For example, the height of the narrower high pressure regions 715 is higher than the height of the transition regions 714. For example, the distance between the narrow high pressure region 715 of the first channel portion and the narrow high pressure region 715 of the second channel portion is the narrowest, so that the two position-limiting rods 305 can clamp the clamped portion at a height higher than the height of the transition region 714 when being arranged at the narrow high pressure region 715, and the width, i.e., the cross-sectional area, of the fifth object is smaller than that of the fourth object.

For example, the wider low-voltage region 711, higher mid-voltage region 712, narrower low-voltage region 713, transition region 714, and narrower high-voltage region 715 of the first channel portion, and the wider low-voltage region, higher mid-voltage region, narrower low-voltage region, transition region, and narrower high-voltage region of the second channel portion communicate, forming a shape resembling an "Ω" character. Thus, the position of the two position-limiting rods 305 in the adjusting channel 710 can be adjusted according to the height and width of the clamped portion of the object by using the adjusting channel 710, so as to adapt to clamping various objects placed on the placing area 601 of the bottom plate 301.
