[0007] Further, the hook includes a hook rod, a hanging ring is connected to the top end of the hook rod, and a hook body is connected to the bottom end of the hook rod. The hook rod, the hanging ring and the hook body are an integral whole.

[0008] Further, the hanging ring is sleeved outside the main rod and can slide relative to the main rod. The included angle between the hook rod and the hook body is set to 45°.

[0009] Further, the cage includes a limit seat and an auxiliary rod. The limit seat is sleeved outside the hook, and both ends of the auxiliary rod are inserted and fixed inside the limit seat.

[0010] Further, the cage further includes a number of screws, and the limit seat and the screws are connected and fixed through a number of screws.

[0011] Further, a slot is opened inside the limit seat, and jacks are opened on both sides of the limit seat. Threaded holes are opened on both sides of the slot at the rear end face of the limit seat.

[0012] Further, the slot is in a "U" - shaped structure, and the slot, the jack and the threaded hole are all connected.

[0013] The utility model provides a flexible lifting tool for installing components inside a box. Compared with the prior art, it has the following beneficial effects:

[0014] This flexible lifting tool for installing components inside a box can flexibly adjust the size of the lifting hook to match different component lifting holes; it has a small size, light weight, is flexible to use, does not require external power, and is easy to operate; it is especially suitable for the scenario where the distance between the component and the shell box body is within 3 mm, and it is difficult to install the component into the box body by conventional methods.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a flexible lifting tool for installing components inside a box, which is composed of a main rod 1, two lifting hooks 2 and a cage 3. Among them,

[0023] Both of the two hooks 2 are composed of an integral hook rod 21, a hanging ring 22 and a hook body 23. The hanging ring 22 is sleeved outside the main rod 1. After being sleeved (when the cage 3 is not installed), the hanging ring 22 can slide relative to the main rod 1. That is to say, the distance between the two hooks 2 can be adjusted. In addition, in order to make the whole hoisting tool easy to use and convenient for hanging the power battery box, the included angle between the hook rod and the hook body is set to 45°;

[0024] In addition, the cage 3 is composed of two limit seats 31, auxiliary rods 32 and several screws 33. Each limit seat 31 is provided with a slot 311, a jack 312 and a threaded hole 313 that communicate with each other. Among them, the slot 311 is set in a "U" shape, and the hook rod 21 is located inside the slot 311. Both ends of the auxiliary rod 32 are inserted into the jacks 312 of the two limit seats 31. After insertion, by screwing the screw 33 into the threaded hole 313, the end of the screw 33 is abutted and fixed to the auxiliary rod 32, so as to assemble the whole cage 3 outside the hook 2, which can stably prevent the hook 2 from swaying during use;

[0025] Please refer to Figure 5 , at both ends of the power battery, a number of downward extension channels B and hook holes A are reserved respectively. The downward extension channels B and the hook holes A are connected. When the hoisting tool of this embodiment is used, after the hoisting tool is assembled, the hook 2 extends into the downward extension channel B, and then the hook body 23 of the hook 2 is hung inside the hook hole A. By lifting upward, the hoisting of the battery pack can be completed. One person can operate a battery pack with a lifting weight of 30KG, and two people can operate a battery pack with a lifting weight of 50KG to achieve the purpose of smoothly placing it into the shell box.
