[0029] Embodiment one:

[0030] As Figures 1-2 shown, the utility model provides a handle device 1, wherein, including: contact part 10, contact part 10 has elasticity, contact part 10 produces elastic deformation under stress state, contact part 10 is arc structure, and the bottom end of contact part 10 is provided with cavity 2;Contact part 10 further includes first contact part 11 and second contact part 12, and first contact part 11 and second contact part 12 are integrated structure, and the vertical distance of first contact part 11 to cavity 2 is greater than the vertical distance of second contact part 12 to cavity 2;Connecting portion 20, connecting portion 20 is arranged at both ends of contact part 10, and contact part 10 and connecting portion 20 are integrally arranged;First contact part 11 and second contact part 12 produce elastic deformation under stress state, when being subjected to jolt collision, external force exerts pressure on first contact part 11, and first contact part 11 promotes second contact part 12 to produce elastic deformation under stress state, so that first contact part 11 is tightly pressed to the inside.

[0031] The contact part 10 is provided with the elastic structure with the camber, in the free state, the handle device 1 is natural upper supply state, makes first contact part 11 and second contact part 12 and there is enough space between cavity 2, is favorable for the finger to stretch into it.Second, in the battery package's packaging box, the handle device 1 is pressed down by external force, makes the whole battery package to be in elastic compression state, is favorable for reducing vibration and eliminating the manufacturing error of containing space, and will not cause the fracture or damage condition.

[0032] The bottom of the connecting part 20 is also provided with a limiting part 30, which is used to engage the handle device 1 and engage the limiting part 30 with the battery casing 3 to perform a lifting action. The limiting part 30 also includes a first limiting part 310 and a second limiting part 320, which are correspondingly provided. The first limiting part 310 is bent in the direction away from the end of the connecting part 20 and is provided to protrude upward, and the second limiting part 320 is bent in the direction away from the end of the connecting part 20 and is provided to protrude upward.

[0033] The first limiting part 310 and the second limiting part 320 are used to prevent the handle device 1 from detaching from the battery casing 3. The first limiting part 310 and the second limiting part 320 are integrally formed with the connecting part 20, which can simplify the structure of the handle device 1 and reduce costs.

[0034] The limiting part 30 and the battery casing 3 are provided with an interference fit in the vertical direction. By providing the first limiting part 310 and the second limiting part 320, the handle device 1 can be locked onto the wall of the cavity in the battery casing 3 with appropriate tightness, so as to reduce noise and impact during vibration.

[0035] The bottom of the limiting part 30 is arc-shaped, which makes the up-and-down locking action of the limiting part 30 smoother. If the bottom of the limiting part 30 is right-angled or square, it may get stuck and damaged or broken when pulled up and down due to the angle.

[0036] This application, by providing contact portions 10, allows the first contact portion 11 and the second contact portion 12 to undergo elastic deformation under stress. When the handle device 1 is subjected to bumps or impacts, the external force applies pressure to the first contact portion 11, causing the second contact portion 12 to also undergo elastic deformation under stress. This causes the first contact portion 11 to press inward, preventing damage or breakage. Therefore, this application achieves the better effect of preventing damage or breakage of the handle device 1 under bumps or impacts, solving the problem of damage or breakage of existing handle devices under bumps or impacts.

[0037] Example 2:

[0040] Further, the accommodation part 33 is provided with an accommodation cavity 34, the accommodation cavity 34 is vertically arranged, the height of the accommodation cavity 34 is adapted to the height of the limiting part 30, the limiting part 30 can move up and down in the accommodation cavity 34, and the handle device 1 can move up and down in the accommodation cavity 34, which can increase the holding space and reduce the overall size of the battery.

[0041] When the battery pack needs to be lifted for movement, the first limiting part 310 and the second limiting part 320 are attached to one end of the accommodation cavity 34, and when the battery pack needs to be placed, the first limiting part 310 and the second limiting part 320 are attached to the other end of the accommodation cavity 34. The movable gear can be adjusted according to actual needs.

[0042] Because the vertical distance from the first contact part 11 to the cavity 2 is greater than the vertical distance from the second contact part 12 to the cavity 2, in actual application, the fingers of the staff have enough space and will not be clamped in the cavity 2.

[0043] Further, the accommodation part 34 is provided with a clamping part 35, the clamping part 35 is recessed corresponding to the top end of the first limiting part 310 and the second limiting part 320, and the clamping part 35 is used to prevent the first limiting part 310 and the second limiting part 320 from moving.
