[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the implementation of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the technical features involved in the different implementations of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 , Figure 6 and Figure 7 As shown, this example includes a top cover body and a handle 2 rotatably connected to the top cover body, the top cover body includes a bottom plate 11 and a box body 12 on the upper end surface, the bottom plate 11 and the box body 12 are integrally formed structures, the bottom plate 11 is covered on the battery box body 3, and the corresponding two side surfaces of the box body 12 are correspondingly provided with insertion holes 15, the handle 2 is an open frame structure, including a vertical rod and a horizontal rod vertically connected to the two ends of the vertical rod, so that one end of the horizontal rod at both ends is connected to the vertical rod and the other end is provided with a load-bearing protrusion 21. When in use, the load-bearing protrusions 21 on the horizontal rods at both ends are correspondingly inserted into the insertion holes 15, so that when the vertical rod is pulled, the battery shell will be lifted through the horizontal rods on both sides, and then the entire battery will be lifted.

[0030] like Figure 4 and Figure 5As shown, a baffle 13 is provided on one side of the outer end surface of the insertion hole 15, so that when the handle 2 is rotated to one side and contacts the baffle 13, due to the obstruction of the baffle 13, the handle 2 can only be selected to this position at most, so as to achieve the limit of the handle 2. When the handle 2 is rotated to the other side and the bottom plate 11, the cross bar and the bottom plate 11 are arranged in parallel, and the outer side of one end of the box body 12 is just located in the frame structure of the handle 2, and the other side of the box body 12 is provided with a charging and discharging port 19. The height of the vertical bar is lower than the height of the box body 12, so that the handle 2 can be "hidden" when it is rotated to one end of the box body 12, and no extra space is occupied.

[0031] like Figure 2 and Figure 3 As shown, an outer positioning ring 16 and an inner positioning ring 17 are arranged in the insertion hole 15, and the inner positioning ring 17 is arranged in the inner cavity of the outer positioning ring 16 and is a hollow structure. A load-bearing column 22 is arranged at the center of the load-bearing protrusion 21, and a through hole 23 is opened in the inner cavity of the load-bearing column 22. The load-bearing protrusion 21 extends to the gap between the outer positioning ring 16 and the inner wall of the insertion hole 15, and the load-bearing column 22 extends to the gap between the outer positioning ring 16 and the inner positioning ring 17. The positioning ring extends to the through hole 23 of the load-bearing column 22, so that the load-bearing protrusion 21 and the insertion hole 15 are mutually matched, and the load-bearing The through hole 23 in the hole is a stepped structure, including a first part and a second part. The diameter of the second part is smaller than that of the first part. The positioning ring passes through the second part and extends to the first part. The screw 24 is inserted in the inner cavity of the inner positioning ring 17 and the screw 24 rod and the inner positioning ring 17 are clamped. At the same time, the diameter of the screw 24 head of the screw 24 is larger than the second part but smaller than the first part, so it does not contact the inner wall of the through hole 23 or the end face of the second part. In this way, when the load-bearing protrusion 21 rotates, it will not interfere with the rotation of the load-bearing protrusion 21, thereby ensuring the smooth rotation of the hand-held device.

[0032] The presence of the baffle 13 limits the rotation radius of the handle 2. In this example, one side of the hand-avoiding position is a vertical structure, and below the vertical structure is an arc-shaped limiting structure 14, and the arc-shaped limiting structure 14 matches the end face of one end of the vertical rod. When the two ends of the handle 2 rotate with the load-bearing protrusion 21, they can only rotate to contact the vertical structure at most, that is, rotate 90 degrees, and it is difficult to exceed 90 degrees. This can effectively prevent the handle 2 from shaking and improve the lifting effect. The arc-shaped limiting structure 14 will not interfere with its rotation, making its rotation smoother.

[0033] The inner and outer positioning rings 17 and 16 are both provided with reinforcing ribs 18 on their peripheries, which improve the strength of both, so that when the load-bearing protrusion 21 lifts the battery, the lifting will not fail due to insufficient strength of the positioning rings. The outer periphery of the load-bearing column 22 is provided with annular reinforcing ribs 25, which are arranged around the outer periphery of the load-bearing column 22 to improve the strength of the load-bearing column 22.

[0034] In order to ensure the sealing of the battery as a whole, the bottom end surface of the insertion hole 15 is a sealing structure, that is, the insertion hole 15 is a blind hole structure and is not connected to the interior of the box body 12, thereby ensuring a sealing and waterproof effect.

[0035] In this example, both ends of the handle 2 are inserted into the insertion hole 15, and due to the presence of the baffle 13, the handle 2 can only rotate within a limited range. When the handle 2 rotates to 90 degrees, Figure 8 As shown, the whole is lifted. When lifting, the load-bearing protrusion 21 and the load-bearing column 22 drive the positioning ring to lift the top cover body, and then lift the battery. After the lifting is completed, the handle 2 is rotated to surround one side of the box body 12 to hide the handle 2.

[0036] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
