[0002] With the development of society, new energy vehicles are becoming more and more common. Most of the parts on new energy vehicles are fixed by screws. Therefore, the most commonly used mechanical equipment for repairing new energy vehicles is a screwdriver. The existing screwdriver includes a handle, a blade connected to the handle, and a blade head connected to the blade head. When using, hold the handle, the blade head is vertically abutted against the screw, and then turn the handle to remove the screw. For new energy vehicles, as the complexity of the mechanical structure becomes higher and higher, more and more screws are hidden deep in the mechanical structure. When it is necessary to disassemble the parts, the blade head of the screwdriver reaches the screw and abuts against the screw vertically, but some lines or pipes above the screw may contact the blade of the screwdriver, generating a force on the blade, making it difficult to ensure that the blade is always perpendicular to the screw when the screwdriver handle rotates. If the blade head is tilted, it may cause damage to the screw, affecting the screwing out of the screw, making it difficult to remove the parts. Summary of the invention

[0029] Reference Figures 1 to 6 , Figure 1 A front view of a mechanical device for facilitating maintenance of new energy vehicles provided by an embodiment of the present invention, Figure 2 A cross-sectional view of a mechanical device for facilitating maintenance of new energy vehicles provided by an embodiment of the present invention, Figure 3 for Figure 2 A schematic diagram of the enlarged local structure of the A area in the middle. Figure 4 A schematic diagram of the structure of a mechanical device for facilitating maintenance of new energy vehicles provided by an embodiment of the present invention before use. Figure 5 for Figure 4 A magnified schematic diagram of the local structure of area B in the middle. Figure 6 A schematic diagram of the structure of a mechanical device used in the maintenance of new energy vehicles provided by an embodiment of the present invention. Figures 1 to 6 As shown, an embodiment of the present invention provides a mechanical device for facilitating the maintenance of new energy vehicles, including: a screwdriver 1, a handle 10 of the screwdriver 1 and a shank 11 are connected through a universal cross shaft 13, and a thread is arranged on the outer periphery of the shank 11, and also includes: a fixing component and a connecting component, the fixing component includes a vent pipe 3, a vacuum suction cup 4 and a vacuum pump 5, the vacuum suction cup 4 is connected to one end of the vent pipe 3, and the vacuum suction cup 4 is connected to the other end of the vent pipe 3, so that the vacuum suction cup 4 can be fixed on a component on one side of the screw 9; the connecting component includes a connecting sleeve 2, one end of the vent pipe 3 is penetrated by the connecting sleeve 2, the vacuum pump 5 is located at the top of the connecting sleeve 2, and the connecting sleeve 2 is threadedly sleeved on the shank 11, so that when the vacuum suction cup 4 can be fixed on a component on one side of the screw 9, the shank 11 of the screwdriver 1 can only rotate along its own axis and move in a direction perpendicular to the screw 9, that is, the blade 12 of the screwdriver 1 always remains perpendicular to the screw 9.

[0030] When it is necessary to unscrew a screw 9 at a deeper position on a new energy vehicle, the cutter head 12 is placed vertically on the screw 9, the vacuum suction cup 4 is placed on the automobile component 8 on one side of the screw 9, and the vacuum pump 5 is turned on to fix the vacuum suction cup 4. Because one end of the vacuum suction cup 4 is connected to the connecting sleeve 2, the position of the connecting sleeve 2 is fixed, and the connecting sleeve 2 is threadedly sleeved on the tool rod 11, so that the horizontal position of the tool rod 11 is fixed without affecting the up and down movement of the tool rod 11, that is, the tool rod 11 of the screwdriver 1 can only rotate along its own axis and move in a direction perpendicular to the screw 9, so that the cutter head 12 of the screwdriver 1 is always kept perpendicular to the screw 9, because the handle 10 and the tool rod 11 are connected by a universal cross shaft. 13 connection, turn the handle 10 to a suitable angle to avoid some lines or pipes above the screw 9, rotate the handle 10 along its axis, the handle 10 rotates along its axis, the handle 10 rotates to drive the tool rod 11 to rotate along its own axis, the tool rod 11 rotates to drive the tool head 12 to rotate, and the screw 9 placed inside the part is rotated and taken out. After taking it out, turn off the vacuum pump 5 and remove the vacuum suction cup 4. By setting the fixing component and the connecting component, when the screwdriver 1 is used to screw out the screw, the tool head 12 of the screwdriver 1 is always perpendicular to the screw 9, reducing the damage to the screw caused by the tilt of the tool head 12, making it easier to screw out the screw, disassemble the parts, and facilitate the maintenance of new energy vehicles.

[0031] The ventilation pipe 3 is a telescopic pipe, so when controlling the vacuum suction cup 4 to be fixed, there is no need to rotate the connecting sleeve 2 every time, making the fixing process simpler and more convenient, reducing the damage to the screw caused by the tilt of the cutter head 12, making it easier to unscrew the screw and disassemble the parts, thereby facilitating the maintenance of the new energy vehicle.

[0032] Refer again Figures 2 to 6 , the reference also includes a compression spring 6, which is sleeved on the vent pipe 3, one end of the compression spring 6 is connected to the connecting sleeve 2, and the other end of the compression spring 6 is connected to the vacuum suction cup 4. The compression spring 6 gives a force to the vacuum suction cup 4, so that the vacuum suction cup 4 is fixed more stably, reducing the damage to the screw caused by the tilt of the cutter head 12, making it easier to screw out the screw, disassemble the parts, and facilitate the maintenance of the new energy vehicle.

[0033] Refer again Figures 1 to 6 , and further includes a protective sleeve 7, which is a retractable sleeve, and is sleeved on the compression spring 6. One end of the protective sleeve 7 is fixedly connected to the connecting sleeve 2, and the other end of the protective sleeve 7 is connected to the vacuum suction cup 4. The protective sleeve 7 sleeves the compression spring 6 so that the compression spring 6 is not exposed, thereby avoiding damage to the compression spring 6 during use due to too many automobile parts or lines.

[0034] The diameter of the protective sleeve 7 is 2-3 mm larger than the diameter of the compression spring 6, which not only avoids the waste of materials due to the protective sleeve 7 being too large in diameter and the large volume requiring a large space for maintenance, but also avoids the protective sleeve 7 being too small in diameter, causing friction between the compression spring 6 and the protective sleeve 7 when it is extended or shortened, thereby causing damage.

[0035] The distance from the edge of the connecting sleeve 2 to the knife bar 11 is equal to the distance from the edge of the protective sleeve 7 to the knife bar 11. The overall volume can be minimized, making the maintenance process more convenient.

[0036] The material of the vent pipe 3 is a hard material, which makes the fixing effect of the cutter head 12 better, reduces the damage to the screw caused by the tilt of the cutter head 12, makes it easier to unscrew the screw, disassemble the parts, and facilitate the maintenance of the new energy vehicle.

[0037] The distance between the vent pipe 3 and the knife rod 11 is 1 cm-2 cm, so that the vent pipe 3 will not be affected during the process of rotating and removing the screw 9, and the volume will not be increased due to the large distance between the two.

[0038] The cutter head 12 is detachably connected to the cutter rod 11 , so that the cutter head 12 can be replaced according to the size of the screw 9 , making it applicable to more types of screws 9 .

[0039] The diameter of the bottom of the vacuum suction cup 4 is 1 cm-3 cm, which not only avoids the vacuum suction cup 4 being too small to affect the fixing effect, but also avoids the vacuum suction cup 4 being too large to be suitable for small parts and occupy space.

[0040] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
