[0001] The invention belongs to the technical field of automobile disassembly and assembly tools, and in particular relates to a bracket disassembly and assembly tool with an avoidance function. Background Art

[0002] When the various components inside the car are laid out, they often overlap and their installation positions are staggered. For example, the installation position of the intercooler condenser is affected, such as Figure 7 When installing the fan shown, there is an obstacle directly above the bolts used to fix the bracket. Traditional screwdrivers and wrenches are difficult to disassemble and assemble the bolts at an inclined angle. It is often necessary to remove the obstacle first before using the screwdriver to disassemble and assemble the bracket, making the disassembly and assembly process of the vehicle inspection more cumbersome.

[0003] Chinese invention patent CN105033918B discloses a universal screwdriver, which mainly includes a first rod and a second rod hinged to each other, and bevel gears meshing with each other are provided at the ends of the rods. However, the above universal screwdriver has shortcomings. When disassembling and assembling relatively tight bolts, there is a lack of stability between the first rod and the second rod. When rotating with force, the direction of the rod is difficult to control, and the engagement between the rod and the bolt is prone to slippage. Summary of the Invention

[0028] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-6 As shown, a bracket disassembly and assembly tool with an avoidance function includes a universal disassembly and assembly component 1, a base structure 2, a pressing structure 3, and a clamping structure 4.

[0031] The universal disassembly assembly 1 is used to disassemble the bolt 6 to avoid obstacles, and includes a rotating rod 11 and a universal joint 14. The bottom of the universal joint 14 is provided with a disassembly head 15;

[0032] The base structure 2 is used to provide support for the rotating rod 11 and includes a base body 21, an hourglass-shaped groove 22 provided inside the base body 21 and corresponding to the rotating rod 11, and two Y-shaped hinge plates 24 hingedly provided on the outer surface of the base body 21. One end of the Y-shaped hinge plate 24 is fixed by the clamping structure 4. The two Y-shaped hinge plates 24 fix the base body 21, which can greatly increase the degree of freedom when fixing the base body 21, so that the base body 21 can adapt to more fixed positions and fixed angles.

[0033] The downward pressing structure 3 is used to press down the rotating rod 11 and tighten the bolt 6, and includes an external threaded column 31 threadedly connected to the thread groove 23 opened on the base body 21. A telescopic guide column 32 is provided at the bottom end of the external threaded column 31. A spring 33 is provided inside the guide column 32 and the external threaded column 31. The bottom end of the guide column 32 is hingedly provided with an arc-shaped pressure plate 35.

[0034] A handle 12 is provided at the upper end of the rotating rod 11. According to actual use requirements, the handle 12 can be a thickened cylindrical handle, or a lever can be provided along the radial direction of the handle 12 to make the handle 12 L-shaped or T-shaped to facilitate rotation and force.

[0035] The universal joint 14 and the disassembly head 15 are detachably connected, wherein a plug-in connection portion 16 is provided between the disassembly head 15 and the universal joint 14, and the connection portion 16 is fixed by a radial screw or a radial pin. A variety of different types of disassembly heads 15 can be provided according to the use requirements. The disassembly head 15 and the universal joint 14 are fixed in a detachable manner, and with the cooperation of the downward pressure structure 3, the disassembly head 15 and the bolt 6 can be prevented from slipping when rotating, and the connection portion 16 can also be prevented from detaching. The disassembly head 15 is one of a cross screwdriver, a flat screwdriver, and an inner angle socket, such as Figure 2 The following is a diagram of a cross screwdriver. Figure 6Schematic diagram of the hexagon socket.

[0036] A limiting end 34 is also provided between the external threaded column 31 and the guide column 32 to prevent the guide column 32 from detaching from the external threaded column 31. The downward pressing structure 3 drives the arc pressure plate 35 to press down by rotating the external threaded column 31. The limiting end 34 is provided to prevent the guide column 32 from moving into the external threaded column 31, and the arc pressure plate 35 can be easily and quickly retracted.

[0037] The surface of the arc pressure plate 35 is provided with a threaded piece 36, and the outer surface of the rotating rod 11 is provided with a fine thread 13 corresponding to the threaded piece 36. By setting the fine thread 13 and the arc pressure plate 35 to engage with each other, the arc pressure plate 35 can better press down the rotating rod 11, and when the rotating rod 11 rotates, the rotating rod 11 is appropriately moved axially to prevent the disassembly head 15 and the bolt 6 from slipping. It can be foreseen that before the rotating rod 11 rotates, the disassembly head 15 is vertically downward and coaxial with the bolt 6 and engages with each other. The arc pressure plate 35 presses down so that the disassembly head 15 and the bolt 6 are tightly engaged. When the bolt 6 is disassembled, the disassembly head 15 is raised in height and pushes up the rotating rod 11. If the rotating rod 11 If it is not retracted, the disassembly head 15 may be caused to tilt, and then the disassembly head 15 and the bolt 6 may slip. Therefore, providing a fine thread 13 can also make the rotating rod 11 retract or feed appropriately during rotation, so as to reduce the amount of tilt of the disassembly head 15, and thus reduce the possibility of slipping (it should be noted that the retraction of the rotating rod 11 through the fine thread 13 is to reduce the amount of tilt of the disassembly head 15, and cannot completely prevent the disassembly head 15 from tilting, and preventing the disassembly head 15 from tilting and slipping only needs to be done in the early stage of disassembling the bolt 6. At this time, the disassembly head 15 and the bolt 6 have a large bite force, and when the bolt 6 is loose, even if the disassembly head 15 is tilted, it will basically not slip).

[0038] The clamping structure 4 includes a clamping portion for fixing to the bracket 5 and a pressing portion for pressing the Y-shaped hinge plate 24. The clamping structure 4 is not only used to fix the base structure 2 at multiple angles, but also used to fix the clamping structure 4 on the bracket 5 instead of holding it.

[0039] The clamping part includes a shell 41, a motor 42 arranged inside the shell 41, a threaded rod 43 arranged at the output shaft end of the motor 42, and a lifting block 44 connected to the threaded rod 43. The bottom end of the shell 41 is provided with two slide grooves 47, and the two slide grooves 47 are slidably provided with clamping petals 46 for clamping the bracket 5. The petals 46 and the lifting block 44 are hingedly provided by a hinge rod 45. The side wall of the slide groove 47 is provided with a side groove 48. The side surface of the petal 46 is provided with at least two guide wheels 49 slidably connected to the side groove 48. The motor 42 drives the two clamping flaps 46 to merge and clamp the bracket 5. Furthermore, a clamping groove 410 is opened inside the shell 41, and the side wall of the clamping groove 410 is slidingly provided with a clamping block 411 for clamping the Y-shaped hinge plate 24. The side wall of the lifting block 44 is provided with a slope for pushing the clamping block 411. The clamping block 411 is pushed to move by the lifting and lowering of the lifting block 44 to clamp and fix the two Y-shaped hinge plates 24. The Y-shaped hinge plates 24 are fixed by clamping, so that the base body 21 can be fixed at multiple angles.

[0040] The specific implementation method is as follows: first, place the clamping structure 4 at a suitable fixed position on the bracket 5, then adjust the position of the base body 21 and the rotating rod 11 so that the disassembly head 15 is engaged with the bolt 6 head-on, then start the motor 42, first push the clamping block 411 to press the Y-shaped hinge plate 24, then the clamping petal 46 clamps the bracket 5 to complete the overall fixation, then rotate the external threaded column 31, the external threaded column 31 applies force through the spring 33 to press the arc-shaped pressure plate 35 on the rotating rod 11, prompting the disassembly head 15 to be pressed against the bolt 6 to prevent slipping, and the rotating rod 11 is driven to rotate by the handle 12, and the rotating rod 11 drives the universal joint 14 to rotate to disassemble the bolt 6, and the fixation is released after the disassembly is completed.

[0041] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
