After the large conical gear 1 rotates, the sleeve 101 at the rear end thereof and the outer end of the internal threaded tube 34 will not make any contact. Each set of telescopic arm equipment 5 includes a lower connecting plate 51, a rectangular sleeve 52, a rectangular movable rod 53, and a rectangular tooth plate 54. The rear end of each lower connecting plate 51 and the front end of one of the helical gears 2 are an integrated structure (the front end of the helical gear 2 has no teeth). The front end of the lower connecting plate 51 has an axial hole, and the inner end of the rectangular sleeve has an integrally formed inner connecting plate 521 with an axial hole. The inner end of the inner connecting plate 521 from front to back is a planar structure. The inner connecting plate 521 of each rectangular sleeve and the front end axial hole of the lower connecting plate 51 are hingedly installed together by a hinge screw. A section of helical tooth-shaped guide groove 55 is provided in the middle of the front and rear parts of the rectangular sleeve 52. The helical teeth of each helical tooth-shaped guide groove 55 are located on the inner side, and the vertical surface of each helical tooth-shaped guide groove 55 is located on the outer side. There is an axial hole in the innermost middle part of the rectangular movable rod 53. One of the rectangular tooth plates 541 has an axial hole at the rear part of the outer end, and the other rectangular tooth plate 542 has an axial hole at the front part of the outer end. The rear axial hole at the outer end of one rectangular tooth plate 541, the front axial hole at the outer end of the other rectangular tooth plate 542 and the innermost middle axial hole of the rectangular movable rod 52 are hinged and installed together through a hinge screw. The middle section of the front side of one rectangular tooth plate 541 and the middle section of the rear side of the other rectangular tooth plate 542 each have a plurality of oblique teeth 59 horizontally, the inclined surface of each oblique tooth 59 is located on the outside, and the vertical surface of each oblique tooth 59 is located on the inside, a positioning rod 56 is welded in the middle of the front and rear ends of the two rectangular tooth plates, and a spring 57 is sleeved between the two positioning rods 56. The rectangular movable rod 52 and the rectangular tooth plate 54 are horizontally sleeved in the rectangular sleeve 52, and the outer end of the rectangular movable rod 53 is a pointed cone structure.A rectangular guide hole is provided in the middle of the outer end of the rectangular sleeve 52, the outer diameter of the rectangular guide rod 53 is smaller than the inner diameter of the rectangular guide hole, the outer diameter of the rectangular movable rod 53 is smaller than the inner diameter of the rectangular sleeve 52, a guide tube 58 communicating with the inner space of the rectangular sleeve is welded in the middle of the front side of the rectangular sleeve 52, a spring 581 is provided in the guide tube 58, an operating rod 582 is installed in the guide tube 58 from front to back, the rear side of the operating rod 582 is located in the rectangular sleeve 52 and is flush with the inner wall of the rectangular sleeve 52 from left to right, the rear side of the guide tube 58 is provided with a cover, the operating rod 582 is located at the rear inner end of the cover and a limiting plate is welded, and the operating rod 582 can be moved along the front of the opening in the middle of the cover After the operator presses the front side of the operating rod 582, the operating rod 582 overcomes the elastic force of the spring 581 and moves, and its rear side moves toward the inner and rear side of the rectangular sleeve 53. After the rectangular movable rod 53 and the rectangular tooth plate 54 are transversely sleeved in the rectangular sleeve 52, when the rectangular movable rod 53 moves outward for a distance, the two rectangular tooth plates 54 overcome the elastic force of the spring 57, and the oblique teeth 59 at the outer ends of the two rectangular tooth plates are respectively located in an oblique tooth-shaped guide groove 55 in the middle of the inner front and rear parts of the rectangular sleeve. Under the action of the oblique tooth surface 59 and the oblique tooth-shaped guide groove 58, the rectangular movable rod 53 and the rectangular tooth plate 54 can move outward but cannot move inward. When the rectangular movable rod 53 and the rectangular tooth plate 54 are located at the inner stop point of the rectangular sleeve 52, the front and rear sides of the two rectangular tooth plates 54 are in contact with the front and rear inner sides of the rectangular sleeve 52 respectively. When the lower connecting plate 51 of the rectangular sleeve 52 and the fixed plate support plate 32 are at an angle of 180 degrees, the front side of the rectangular sleeve 52 is located outside the wheel hub 6 of the wheel. When the lower connecting plate 51 of the rectangular sleeve 52 and the fixed plate support plate 32 are at an angle of 90 degrees, the front side of the rectangular sleeve 52 is located inside the wheel hub 6 of the wheel. The positioning plate 4 includes an externally threaded rod 41 and a front disc 42. The front end of the externally threaded rod 41 is welded to the middle of the rear side of the front disc 42. The rear external thread of the externally threaded rod 41 is screwed into the internal thread of the internally threaded tube 34, and the rear end of the positioning plate 4 is installed in the internally threaded tube 34. The lower connecting plate 51 of the rectangular sleeve 52 and the fixed plate support plate 32 are at an angle of 180 degrees. When the front side of the rectangular sleeve 52 is located outside the wheel hub 6, the front disc 42 is surrounded by a very small distance from the inner side of the inner connecting plate 521 of the inner side end of the rectangular sleeve of the five sets of telescopic arm equipment. There is an operating rod in the middle of the front side of the front disc 42 (for convenient manual rotation of the front disc 42).

[0017] Figure 1 , 2As shown in Figures 3 and 4, when the present invention is applied, the present invention can be installed in the wheel hubs of multiple wheels of a car as needed. The present invention is not used. When the front side of the lower connecting plate 51 of the five sets of rectangular sleeves 52 and the fixed plate support plate 32 are at a 90-degree angle, the front side of the rectangular sleeve 52 is located in the wheel hub 6, achieving a good storage effect without causing any influence on the movement of the wheel. When it is needed, the operator rotates the operating rod 102 of the conical gear 1 located on the fixed plate in the middle of the multiple automobile wheel hubs counterclockwise in the vertical direction, and then the conical gear 1 drives the multiple bevel gears 2 to rotate clockwise in the horizontal direction. The multiple bevel gears 2 respectively drive the multiple support plates 32 to move inward, and the multiple support plates 32 respectively drive the lower connecting plates 51 of the multiple sets of rectangular sleeves 52 to move inward along the hinge point of the front shaft hole of the support plate 32. When the five sets of rectangular sleeves 52 and the fixed plate support plate are at an angle of 180 degrees, the operator stops rotating the conical gear 1 at this moment, and then screws the rear end of the external threaded rod 41 of the positioning plate into the internal threaded tube 34 of the fixed plate. The front disc 42 is respectively spaced very close to the rear side of the inner connecting plate 521 at the inner end of the rectangular sleeve of the multiple sets of telescopic arm equipment by an extremely small distance (0.5mm). This ensures that after the automobile tire is stressed, the inner connecting plate 521 at the inner end of the rectangular sleeve of the multiple sets of telescopic arm equipment will not move too much inward. When the rectangular movable rod 53 moves outward for a certain distance, the two rectangular tooth plates 54 overcome the elastic force of the spring 57, and the oblique teeth at the outer ends of the two rectangular tooth plates 54 are respectively located in an oblique tooth-shaped guide groove 55 in the middle of the front and rear parts of the rectangular sleeve. Under the action of the oblique tooth surface and the oblique tooth guide groove 55, the rectangular movable rod 53 and the rectangular tooth plate 54 can move outward but cannot move inward. The outer end of the rectangular movable rod is higher than the outer surface of the tire. At this moment, the outer rear end of the rectangular sleeve 52 of the multiple sets of telescopic arm equipment is located in the wheel hub 6, and the outer rear end is only about 2mm away from the wheel hub 6. In this way, during the subsequent driving of the wheels, due to the limitation of the wheel hub 6, the rectangular movable rod 54 will not have a large front-to-back displacement, thereby ensuring normal use. The telescopic arm device 5 is fixed by a positioning plate to prevent displacement. When the vehicle is moving, the pointed cone part at the front end of the rectangular movable rod 53 can be effectively inserted into the surface of snow or ice, effectively preventing the tires of the vehicle from slipping during movement, thereby effectively improving the safety of the vehicle driving on snowy and icy ground.When the present invention is not in use, the operating rods 582 of the five telescopic rod devices 5 are pressed respectively, and the operating rods 582 overcome the elastic force of the springs 581 and move, and the rear side of the operating rods 582 moves toward the inner rear side of the rectangular sleeve 53, and the distance between the two rectangular tooth plates 54 is reduced. Then the operator can store the rectangular movable rod 54 inward into the rectangular sleeve 52, and then rotate the conical large gear 1 located on the fixed disk in the middle of the multiple automobile wheel hubs clockwise in the vertical direction. When the front side of the lower connecting plate 51 of the rectangular sleeve and the fixed disk support plate are at a 90-degree angle, the front side of the rectangular sleeve 52 is located in the wheel hub 6 of the wheel, which is convenient for the storage of the present invention at ordinary times. Based on the above, the present invention has a good application prospect.
