[0030] Referring to Figures 1 to 6 , the present application provides a nut screwing tool, comprising a body 10, a docking groove 20, and an interface 30. The body 10 has a height direction Z and a width direction X. Along the height direction Z, the body 10 has a top portion 101 and a bottom portion 102, and the top portion 101 and the bottom portion 102 have a side portion 103 therebetween. The docking groove 20 is provided on the body 10 and communicates with the bottom portion 102, and is used for sleeving a nut 100 to be screwed. The body 10 is provided with a notch 40 extending along the width direction X and communicating with the docking groove 20 and the side portion 103; the notch can be connected with the nut to be screwed to stop rotation. The interface 30 is provided on the body 10 and is provided on the top portion 101, and is used for docking with a screwing tool.

[0031] It can be understood that, referring to Figure 6 , during screwing operation, the body 10 is sleeved on the nut 100 from the side of the nut, the notch 40 is just docked with the tangent surface of the side of the cylindrical nut 100, and the rest of the nut is placed in the docking groove 20. In this state, the inner wall of the notch 40 and the tangent surface on the nut are in close contact with each other, so that the nut cannot rotate relative to the body 10, and the two are in stop rotation cooperation, so that the rotation of the tool can drive the nut to rotate, and the screwing operation of the nut is adapted. At the same time, the interface 30 is arranged on the top portion 101 of the body 10, after the interface 30 is docked with the screwing tool, the screwing tool can be located outside the battery pack, and after being started, drives the body 10 to rotate around the axis of the interface 30, and the nut is screwed through the tool body 10, so that the screwing operation space is small, and the screwing operation of the nut in the battery pack is better adapted.

[0032] Further, the interface 30, the docking slot 20 and the body 10 are coaxially arranged. In the screwing operation, the body 10 rotates around its axis, and the required screwing space is only the width of the body 10, which has small space requirement and wider application range.

[0033] In an embodiment, the body 10 includes a first set 11 and a second set 12. The first set 11 and the second set 12 are detachably connected. In the height direction Z, the first set 11 is above the second set 12, and the interface 30 is arranged on the first set 11.

[0034] Further, the docking slot 20 includes a first slot 21 and a second slot 22, and the notch 40 includes a first notch 41 and a second notch 42. The first slot 21 and the first notch 41 are arranged on the first set 11, and the second slot 22 and the second notch 42 are arranged on the second set 12. The first slot 21 and the first notch 41 are connected to form a first U-shaped slot 51, and the second slot 22 and the second notch 42 are connected to form a second U-shaped slot 52. The U-shaped structure can be well fitted with the cut surface on the nut, so that the nut and the notch 40 are not easy to slip and cannot be driven to rotate, thereby avoiding the occurrence of failure.

[0035] In one of the embodiments, the distance between the two opposite surfaces of the first U-shaped slot 51 is L1, and the distance between the two opposite surfaces of the second U-shaped slot 52 is L2, and L1 and L2 satisfy the relationship: L1 is greater than L2.

[0036] As can be understood, since the sizes of the two U-shaped slots are not the same, and the width of the second U-shaped slot 52 at the lower part is smaller. Therefore, it is difficult to process the two U-shaped slots at one time, and after the body 10 is divided into two parts, the processing difficulty is reduced, and the processing is more convenient.

[0037] Secondly, in the knob operation, the second U-shaped slot 52 mainly stops rotating with the cut surface, and the nut is placed in the first U-shaped slot 51. Therefore, by replacing the second body 10 to adjust the width of the second U-shaped slot 52, more types and specifications of nuts can be fitted, and the cost is effectively reduced.

[0038] Further, the diameter of the arc surface of the first U-shaped slot 51 is R1, and L1 and R1 satisfy the relationship: L1 = R1. Under this proportion, the maximum specification of the notch 40 can be set, so that the first U-shaped slot 51 can be fitted with nuts of various specifications.

[0039] Further, the diameter of the arc surface of the second U-shaped slot 52 is R2, L2 and R2 satisfy the relationship: L2 = 0.75R2-0.8R2; and R1 and R2 satisfy the relationship: R1 = R2.

[0040] Exemplarily, the value of L2 can be 0.75R2, 0.76R2, 0.77R2, 0.78R2, 0.79R2, 0.8R2, and the like. Of course, it can also be selected according to actual needs, which will not be repeated here.

[0041] In an embodiment, the first set 11 is provided with a plurality of first connecting holes 61 at the bottom 102, and the second set 12 is provided with a plurality of second connecting holes 62 at the top 101. The plurality of first connecting holes 61 and the plurality of second connecting holes 62 are respectively arranged along the height direction Z, and the plurality of first connecting holes 61 and the plurality of second connecting holes 62 correspond one by one.

[0042] It can be understood that the first connecting hole 61 and the second connecting hole 62 can be penetrated from top to bottom by bolts, screws and the like (not shown in the figure), and locked, so as to realize the detachable connection of the first set 11 and the second set 12, the overall structure is simple, and the operation is simple.

[0043] Exemplarily, the plurality of first connecting holes 61 are distributed along the circumference of the first set 11. The plurality of second connecting holes 62 are distributed along the circumference of the second set 12. The distribution is more uniform, and the connection between the two sets is more stable.

[0044] Exemplarily, the number of the first connecting hole 61 and the second connecting hole 62 is three respectively. Of course, the specific number can also be selected according to actual needs.

[0045] In an embodiment, along the height direction Z, the second set 12 is provided with an anti-drop column 71 at the top 101, and the anti-drop column 71 is arranged in the direction of the first set 11. The first set 11 is provided with an anti-drop port 72 at the top 101, and the anti-drop column 71 is inserted and matched with the anti-drop port 72.

[0046] It can be understood that even if the first set 11 and the second set 12 are not connected by screws and the like, the connection of the anti-drop column 71 and the anti-drop port 72 can also realize that the first set 11 and the second set 12 will not be shaken off, and the structure is simplified.

[0047] Of course, in other embodiments, the connecting hole and the anti-drop column 71 can also exist at the same time, and the connection stability is stronger.

[0048] Further, the body 10 is in a cylindrical structure. The space occupied is relatively smaller, and the space for screwing operation is smaller.

[0049] In an embodiment, along the height direction Z, the first set 11 is provided with a convex part 80 at the top 101, and the interface 30 is arranged at the top 101 of the convex part 80. The width of the convex part 80 is smaller than the width of the first set 11. The convex part 80 can be directly cut from the first set 11, which effectively reduces the weight of the first set 11, realizes light weight, and is more labor-saving during screwing operation.

[0050] Preferably, the convex portion 80 is also a cylindrical structure for easy processing. Exemplarily, the interface 30 is shaped to fit a screw gun tip, which is not described in detail.

[0051] Any combination of the technical features in the above-described embodiments can be made, and to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered as the scope of the description.

[0052] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
