[0004] However, this bolt remover cannot flexibly adapt to various specifications or types of bolts for effective installation or removal when removing or installing bolts of different models. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bolt removal and installation tool for automobile tire repair, thereby solving the problem that bolt removal and installation tools cannot be flexibly applied to the removal and installation of different types of bolts.

[0006] This utility model provides a bolt removal and installation tool for automobile tire repair, including a handle. One end of the handle is connected to a round rod via a bearing. A rubber sleeve is connected to the round rod. A bevel gear is connected to the end of the round rod away from the handle. A bevel gear is provided at the bottom of the bevel gear. The bevel gear and the bevel gear are meshed together. A rotating rod is provided inside the bevel gear. The rotating rod passes through the bevel gear and extends to both ends. A bearing seat is connected to the top of the rotating rod. A removal and installation sleeve is provided at the bottom of the rotating rod.

[0007] Optionally, the rotating rod is hollow inside and equipped with a pressing rod. The top of the pressing rod passes through the rotating rod and extends outward. The extended end is connected to a pressing plate. A spring is provided below the pressing plate. The spring is sleeved on the outside of the pressing rod and its bottom is connected to a positioning plate. The end of the positioning plate is welded to the inner wall of the protective shell. A pressing ball is welded to the bottom of the pressing rod. This is to make the bolt removal and installation tool simpler and faster in the process of replacing different models of replacement sleeves.

[0008] Optionally, the bottom of the rotating rod is square and a circular through groove is provided in the middle, with metal balls connected to both ends of the groove.

[0009] Optionally, the mounting and disassembling sleeve has a square groove inside, and circular grooves are symmetrically formed on both sides of the center of the square groove.

Detailed Implementation

[0021] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and should not be construed as limiting its scope of protection.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility belongs.

[0023] Example 1:

[0024] like Figures 1-3As shown, a bolt removal and installation tool for automobile tire repair according to an embodiment of this utility model includes a handle 1. The handle 1 is made of rubber, and its outer surface has multiple vertical strips to increase friction and improve grip comfort and friction. One end of the handle 1 is connected to a round rod 3 via a bearing 2. A rubber sleeve 21 is connected to the round rod 3. The rubber sleeve 21 increases the friction between the hand and the round rod 3 when the round rod 3 is rotated, making it easier for the user to rotate the round rod 3. When the round rod 3 is rotated, the operator holds the handle 1 to maintain the stability of the device. A bevel gear 10 is connected to the end of the round rod 3 away from the handle 1. A bevel gear 14 is provided at the bottom of the bevel gear 10. The bevel gear 10 and the bevel gear 14 are meshed together. A rotating rod 13 is provided inside the bevel gear 14. The rotating rod 13 passes through the bevel gear 14 and extends to both ends. A bearing seat 11 is connected to the top of the rotating rod 13. The bottom of the rotating rod 13 is equipped with a disassembly sleeve 6. The bearing seat 11 at the upper end of the rotating rod 13 is connected to the inner wall of the protective shell 4 by bolts. One end of the protective shell 4 is connected to the round rod 3 by the second bearing 9. The protective shell 4 serves to protect the internal working parts and prevent dust. The end of the round rod 3 away from the first bevel gear 10 passes through the handle 1 and is connected to a hexagonal groove 8. The hexagonal groove 8 is connected to the end of the handle 1 by bearings. By inserting an Allen wrench into the hexagonal groove 8 at the end of the round rod 3, the round rod 3 is rotated manually, which drives the first bevel gear 10 to rotate. Through the meshing of the first bevel gear 10 and the second bevel gear 14, the rotating rod 13 is rotated, which causes the disassembly sleeve 6 at the bottom of the rotating rod 13 to rotate, thereby tightening or loosening the nut. This makes the bolt disassembly and assembly process more labor-saving, and the tightening or loosening of the nut can be manually adjusted to achieve a better disassembly and assembly effect.

[0025] Example 2:

[0026] like Figure 2 and Figure 4As shown, a bolt removal and installation tool for automobile tire repair according to an embodiment of the present invention includes a rotating rod 13. The rotating rod 13 is hollow inside and has a pressing rod 18. The pressing rod 18 is slidably connected to the inner wall of the rotating rod 13. The top end of the pressing rod 18 passes through the rotating rod 13 and extends outward. A pressing plate 20 is connected to the extended end. The pressing plate 20 is T-shaped and extends downward at its edge. A pressing rubber plate 5 is connected to the top of the protective shell 4. The pressing rubber plate 5 is located above the pressing plate 20. A spring 12 is provided below the pressing plate 20. The circumference of the spring 12 is slightly smaller than that of the pressing plate 20. The spring 12 is sleeved on the outside of the pressing rod 18 and a positioning plate 17 is welded to the bottom. The end of the positioning plate 17 is welded to the inner wall of the protective shell 4. A circular groove slightly larger than the size of the pressing rod 18 is opened in the middle of the positioning plate 17 so that the pressing rod 18 can slide in the middle of the positioning plate 17 without being obstructed. A pressing ball 19 is welded to the bottom of the pressing rod 18. The bottom of the rotating rod 13 is square and a circular through groove is opened in the middle. Metal balls 15 are connected to both ends of the groove. The groove below the metal balls 15 inside the rotating rod 13 is for receiving. The design allows the metal ball 15 to slide downwards and inwards into the rotating rod 13. The disassembly sleeve 6 has a square groove inside, with symmetrical circular grooves 16 on both sides of the center of the square groove. The disassembly sleeve 6 is replaceable and comes with various sizes of replacement sleeves 7. When the disassembly sleeve 6 needs to be replaced, pressing the pressing plate 20 causes the pressing rod 18 to slide inside the rotating rod 13. As the pressing rod 18 slides downwards, its bottom pressing ball 19 moves inwards and downwards into the rotating rod 13. After this movement, the metal balls 15 on both sides are no longer squeezed by the middle pressing ball 19, and the metal... The metal ball 15 moves downward inside the rotating rod 13. Since the metal ball 15 slides out of the circular groove 16 of the disassembly sleeve 6, the disassembly sleeve 6 can be easily removed and replaced with a new one. After the new one is placed in the fixed position, the pressing plate 20 is released, and the pressing rod 18 is reset under the action of the spring 12. The pressing ball 19 slides upward to squeeze the metal ball 15 to move. Since there is a protrusion blocking the groove above the metal ball 15, the metal ball 15 can only reset along the original path and extend out of the circular groove on the rotating rod 13 to get into the circular groove 16 of the new disassembly sleeve 6.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, when using it, first assemble all the components, replace the required model of the disassembly and assembly socket 6, place the disassembly and assembly socket 6 on the bolt of the car tire to be disassembled and assembled, insert an Allen wrench into the hexagonal groove 8 at the end of the round rod 3, manually rotate the wrench to rotate the round rod 3 and drive the bevel gear 10 to rotate. Through the meshing of the bevel gear 10 and the bevel gear 2 14, the rotating rod 13 is driven to rotate, causing the disassembly and assembly socket 6 at the bottom of the rotating rod 13 to rotate, thereby tightening or loosening the nut, making the bolt disassembly and assembly process more labor-saving. Moreover, the tightening or loosening of the nut can be manually adjusted to achieve a better disassembly and assembly effect. When disassembling the bolt, the bolt can be pre-loosened by using an Allen wrench, and then directly rotate the screw. The rubber sleeve on the rotating rod 3 enables rapid rotation of the rod 3, accelerating the disassembly of the bolts. When the disassembly sleeve 6 needs to be replaced, the pressing plate 20 is pressed to make the pressing rod 18 slide inside the rotating rod 13. When the pressing rod 18 slides downward, its bottom pressing ball 19 moves towards the lower interior of the rotating rod 13. After moving, the metal balls 15 on both sides are no longer squeezed by the middle pressing ball 19, and the metal balls 15 move towards the lower interior of the rotating rod 13. Since the metal balls 15 slide out of the circular groove 16 of the disassembly sleeve 6, the disassembly sleeve 6 can be easily removed and replaced with a new one. When the new one is placed in the fixed position, the pressing plate 20 is released, and the pressing rod 18 is reset under the action of the spring 12. The pressing ball 19 slides upward, thereby squeezing the metal ball 15 to move and be inserted into the circular groove 16 inside the replaced disassembly sleeve 6.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
