[0023] The following further describes the present invention with reference to the drawings: Embodiment

[0024] Refer to Figures 1-3 , a frame for a new type of pet push tool cart, including a frame composed of a connecting seat 1, a support plate 7, legs 11 and a push rod 15. Among them: two L-shaped notches 3 are evenly arranged on the upper surface of the connecting seat 1 for connecting with the support plate 7 and the push rod 15, and three U-shaped openings 5 are evenly arranged on the bottom surface of the connecting seat 1 for connecting with the legs 11; one end of the support plate 7 is rotatably installed in one of the L-shaped notches 3; one end of the push rod 15 is rotatably installed in the other L-shaped notch 3, and the rotation angle of the push rod 15 is from 0 degrees to 60 degrees; there are three legs 11, which are arranged in a triangular frame shape after being unfolded to ensure stability during use and at the same time reduce the overall weight, and one end of each of the three legs 11 is rotatably installed in the corresponding U-shaped opening 5;

[0025] As Figures 1-3 shown, on both sides of the corner of the L-shaped notch 3 where the support plate 7 is installed, elastic protrusions 4 are fixedly installed on each side, and the elastic protrusions 4 divide the L-shaped notch 3 into two parts. During use, place the support plate 7 below the elastic protrusions 4. At this time, the support plate 7 is parallel to the ground, and the rotation of the support plate 7 can be restricted;

[0026] A threaded hole 2 is penetrated and opened at the center of the surface of the connecting seat 1, and a limit bolt 14 for restricting the rotation of the three vehicle legs 11 is installed in the threaded hole 2 by threading. Through the arrangement of the limit bolt 14, after the three vehicle legs 11 are unfolded, the limit bolt 14 can be rotated to make the bottom end of the limit bolt 14 leak out from the bottom of the threaded hole 2 and contact the tops of the three vehicle legs 11. In this way, the three vehicle legs 11 are fixed to ensure the stability after the three vehicle legs 11 are unfolded; two L-shaped notches 3 are arranged at mirror positions with the threaded hole 2 as the center;

[0027] A sleeve 9 for installing a pet basket is pluggably installed on the support plate 7 so as to be connected to the pet basket for placing pets through the sleeve 9.

[0028] A rotating shaft 6 is fixedly installed in each of the U-shaped openings 5 to ensure the stability between the vehicle leg 1 and the connecting seat 1 and the smoothness during the rotation process, and the rotating shaft 6 is rotatably connected to one end of the corresponding vehicle leg 11.

[0029] One end of the vehicle leg 11 is penetrated and opened with a shaft hole 13, and the other end of the vehicle leg 11 is rotatably installed with a roller 12 to ensure the smoothness during walking on the ground; the vehicle leg 11 is sleeved on the rotating shaft 6 through the shaft hole 13, and the shaft hole 13 is rotatably connected to the rotating shaft 6.

[0030] Two elastic barbs 8 are uniformly and fixedly installed at the other end of the support plate 7, and the elastic barbs 8 are clamped with the sleeve 9 to ensure the stability of the sleeve 9 on the support plate 7 and at the same time facilitate the separate disassembly and assembly between the sleeve 9 and the support plate 7;

[0031] It should be noted that, under normal circumstances, the distance between the two elastic barbs 8 is greater than the width of the through hole 10.

[0032] A through hole 10 for clamping with the elastic barb 8 is opened at one end of the sleeve 9; the barb end of the elastic barb 8 leaks out from the through hole 10 so as to separate the elastic barb 8 from the sleeve 9.

[0033] In this embodiment, when in use, as Figure 1 shown, unfold the vehicle legs 11 and rotate the limit bolt 14 clockwise to make the bottom end of the limit bolt 14 leak out from the bottom of the threaded hole 2 and contact the tops of the three vehicle legs 11. In this way, the three vehicle legs 11 are fixed;

[0034] Then rotate the support plate 7 so that the support plate 7 is below the elastic protrusion 4. At this time, the support plate 7 will be parallel to the ground; at the same time, rotate the hand push rod 15 to adjust the angle of the hand push rod 15;

[0035] After adjustment, the two elastic hooks 8 are squeezed inward at the same time, so that the distance between the two elastic hooks 8 is smaller than the width of the through hole 10, so that the sleeve 9 can be removed from the support plate 7, and then the sleeve 9 is fixedly installed on the bottom of the pet basket, so that the pet basket can be installed on the support plate 7 through the sleeve 9;

[0036] When the pet basket is not in use and needs to be stored later, the pet basket only needs to be removed from the support plate 7 through the sleeve 9; then the limiting bolt 14 is rotated counterclockwise to retract the bottom of the limiting bolt 14 into the threaded hole 2, and the three legs 11 can be rotated to make the three legs 11 close to each other; then the support plate 7 is rotated to make the support plate 7 above the elastic protrusion 4, and the support plate 7 is perpendicular to the ground; at the same time, the push rod 15 is rotated to make the push rod 15 perpendicular to the ground; in this way, the whole is shrunk together for storage and carrying.

[0037] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
