Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in combination with the following embodiments. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Example 1

As shown in fig. 1, 3, 5 and 6, the first fixture 3 includes an elastic sheet 31 and a hook 32, the elastic sheet 31 is made of an insulating and elastic material such as rubber, and the hook 32 is made of a harder material such as steel. One end of the elastic sheet body 31 is provided with a plurality of through holes 312, the other end of the elastic sheet body 31 is provided with a plurality of tongues 311, and the tongues 311 are provided with hanging holes 3111; the hook member 32 has a flat plate at the bottom, which has a width slightly smaller than that of the steel row 1, and a plurality of hooks 321 are provided at the upper portion of the hook member 32. The hook 321 passes through the through hole 312, so that the flat plate shape of the bottom of the hook 32 is located below the elastic sheet body 31, the hook 321 is located above the elastic sheet body 31, and the hook body of the hook 321 faces the tongue 311.

When the hook is used, as shown in fig. 3, the flat plate at the bottom of the hook 32 is placed on the upper surface of the steel bar 1, then the elastic sheet body 31 is wound around the steel bar 1 for a circle, the hanging hole 3111 is sleeved on the hook 321, at this time, the hook 32 is pressed inside and cannot be turned over, and the hanging hole 3111 cannot be unhooked. The elastic blade 31 is dimensioned so that it can be placed against the steel row 1 with a certain tension. The tongue 311 has a relatively narrow width and is easily pulled, and the width of the hanging hole 3111 is preferably greater than the width of the hook 321, so that the hook 321 can be easily put on. When the specification of the battery piece is more, a plurality of sets of first tools 3 with corresponding lengths (the total length of the steel row 1 minus the length of the battery piece is divided by two) are required to be prepared. After the first fixture 3 is sleeved on the two ends of the steel bar 1, the retractable needle 21 at this position cannot be directly contacted with the first fixture, but is contacted with the elastic sheet body 31, so that short circuit is avoided.

Example 2

Referring to fig. 2, 4 and 7, the second fixture 4 is made of rubber, a cavity 41 is formed inside the second fixture 4, a step 42 is formed at the lower portion of the cavity 41, a tapered surface 43 is formed below the step 42, the tapered surface 43 is obtained by removing a truncated cone from the second fixture 4, the tapered surface 43 is communicated with the cavity 41, and a disc-shaped tray 44 is formed outside the second fixture 4.

When in use, as shown in fig. 7, the side of the second tooling 4 with the conical surface 43 can be directly sleeved on the retractable needle 21 downwards, and the existence of the conical surface 43 makes the process easier. The step 42 can be clamped below the thicker part of the retractable needle 21, so that the retractable needle is not easy to fall off. After the retractable needle 21 is sleeved on the second fixture 4, the retractable needle 21 cannot directly contact with the lower part of the steel bar 1, so that short circuit is avoided. Only a plurality of second tools 4 are needed to be prepared and sleeved on the corresponding telescopic needle 21 needing insulation, and short circuit can be avoided. When the size of the battery is increased, the second tool 4 can be taken down by holding the two sides of the tray body 44 with fingers and pulling upwards.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
