Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1, which is a schematic structural diagram of a gun head clamp 1 of the nitrogen blow-drying apparatus of the present invention.

The gun head taking clamp 1 of the nitrogen blow-drying instrument comprises two clamping jaws 2, four synchronizing shafts 3, four springs 4, a first clamping mechanism 5 and a second clamping mechanism 6.

The two clamping jaws 2 are spring clamps and comprise a first clamping finger 21, a second clamping finger 22 and a V-shaped spring 23. The first claw finger 21 and the second claw finger 22 are arranged side by side, the middle parts of the first claw finger and the second claw finger are respectively provided with a half through hole, a cavity for accommodating the V-shaped spring 23 is formed together, and two ends of the V-shaped spring 23 are respectively abutted and fixed with the outer walls of the first claw finger 21 and the second claw finger 22 to form a spring clamp structure. The specific structure is similar to that of a common spring clip, and details are not repeated.

Of the four synchronizing shafts 3, two are fixed to both ends of the first finger 21, and two are fixed to both ends of the second finger 22. Each synchronizing shaft 3 is sleeved with the spring 4, and two ends of the spring 4 are respectively abutted to the two clamping jaws 2. Limiting heads 31 are respectively arranged at two ends of the synchronizing shaft 3 to limit the clamping jaw 2 between the limiting heads.

One side of the first claw finger 21, which is close to the second claw finger 22, is provided with a cavity, and the inner walls of the cavities opposite to each other are respectively provided with a convex strip 25 along the length direction.

First fixture 5 includes left half 51, right half 52, and the two is equipped with on the outer wall of keeping away from each other with the recess 24 of sand grip 23 adaptation. Different clamping mechanisms can be replaced according to different nitrogen blowing instruments. The side of the left half 51 and the right half 52 close to each other is sequentially provided with 6 semicircular rubber pads 53 at intervals consistent with the needle of the nitrogen blow-drying instrument. The circle center of the rubber pad 53 is also provided with a through hole smaller than the diameter of the needle.

The structure of the second clamping mechanism 6 is similar, and 6 through holes with the diameter larger than that of the needle head and smaller than that of the gun head are arranged on one side, close to the second clamping mechanism, of the nitrogen blow-drying instrument at intervals consistent with the needle head of the nitrogen blow-drying instrument.

In specific implementation, the two clamping jaws 2 are compressed along the synchronizing shaft 3, so that the spring 4 is pressed. And simultaneously pressing the handles of the two clamping jaws 2 to open the end provided with the clamping mechanism. And inserting the opened end between the needles of the nitrogen blowing instrument to enable the through holes of the first clamping mechanism 5 and the second clamping mechanism 6 to clamp the needles one above the other respectively.

The through hole of the first clamping mechanism 5 has larger friction force with the needle head due to the arrangement of the rubber pad 53; the through hole of the second clamping means 6 has almost no friction due to its larger diameter than the needle.

Then released, the spring 23 spreads the two jaws 2 apart. Wherein the first clamping mechanism 5 remains stationary; and the second clamping mechanism 6 moves downwards to eject the gun head.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
