As a further description of the above technical solution:

the fixed part is including two sets of telescopic links, and is a set of the first clamp of telescopic link top fixedly connected with, another group telescopic link top fixedly connected with second clamp, spring and this internal table wall elastic connection of cutter are passed through to first clamp bottom, rotate through the pivot between first clamp and the second clamp and be connected, one side fixed connection of pivot is kept away from to first clamp and second clamp.

As a further description of the above technical solution:

irregular grooves are formed in the inner surface wall of the first clamp and the inner surface wall of the second clamp.

As a further description of the above technical solution:

first clamp and second clamp all are half arc type structure.

As a further description of the above technical solution:

the outer surface wall of the cutter body is coated with an anticorrosive coating.

As a further description of the above technical solution:

and one side of the first clamp and one side of the second clamp far away from the rotating shaft are fixedly connected through a bolt.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, during the use, close soon with hickey and screw thread head on the cutter body, close the back that finishes soon, pull out first clamp and second clamp from the cutter, it is tensile to drive telescopic link and spring, the spring takes place to deform, first clamp and the junction of second clamp block to hickey and screw thread head, close the bolt soon, fixed first clamp and second clamp, spring and telescopic link have down the pulling force to first clamp and second clamp simultaneously, it is not hard up to avoid hickey junction to take place to become flexible, and then the result of use of current centre gripping arm base processing cutter has been improved.

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. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: centre gripping arm base processing cutter, including cutter body 1 and screw thread head 9, 1 exterior wall of cutter body is equipped with

smear metal portion

6, and 1 inside hickey 10 that is equipped with of cutter body, 1 exterior wall of cutter body are seted up flutedly 8, still including:

and the fixing part is arranged in the tool body 1 to further reinforce the joint of the threaded interface 10 and the threaded head 9.

Specifically, as shown in fig. 2, the fixed part is including two sets of telescopic links 7, the first clamp 2 of 7 top fixedly connected with of a set of telescopic link, another 7 top fixedly connected with second clamps 4 of a set of telescopic link, 2 bottoms of first clamp are through spring 5 and the interior table wall elastic connection of cutter body 1, rotate through the pivot between first clamp 2 and the second clamp 4 and be connected, one side fixed connection of pivot is kept away from with second clamp 4 to first clamp 2, stretch out first clamp 2 and second clamp 4 during the use, when not using, 4 blocks of first clamp 2 second clamp are inside cutter body 1, the aesthetic measure has been improved when practical.

Specifically, as shown in fig. 2, irregular grooves are formed in the inner surface walls of the first clamp 2 and the second clamp 4, and the joint of the threaded connector 10 and the threaded head 9 is attached to the structure and the joint of the threaded head.
