[0039] As shown in Figures 1-5 , the structure of the clamp 2 is introduced as follows:

[0040] (1) The clamp 2 comprises a limiting tube 4, the frame 1 is fixedly provided with a seat 22, the limiting tube 4 is horizontally fixedly installed on the seat 22, a chuck 5 is coaxially inserted into the limiting tube 4, the inner end of the chuck 5 is an insertion end, and the outer end of the chuck 5 is a multi-petal structure, so that the inner sides of the petals together form a clamping area for clamping a corresponding end of the radio frequency connector; the outer sides of the petals together form a tapered guide surface with a diameter gradually decreasing along the insertion direction of the chuck 5 relative to the limiting tube 4, and the overall structure of the chuck 5 can be represented by Figure 5 , in this figure, the top end of the chuck 5 is outward tapered due to the tapered guide surface, and it can be known from Figure 4 that when installing, the chuck 5 is inserted into the limiting tube 4 by the bottom end, when clamping and fixing the radio frequency connector, the radio frequency connector is first inserted into the outward tapered end of the chuck 5, and then an axial movement tendency is applied to the chuck 5, as shown in Figure 4 , the movement tendency applied is horizontal left movement, at this time, the chuck 5 as a whole moves horizontally left, until the outward tapered end of the chuck 5 is in abutment with the limiting tube 4 and remains, due to the multi-petal design of the chuck 5, the outward tapered end of the chuck 5 is retracted and forms a clamping area in this process, the formation of the clamping area can clamp and fix the radio frequency connector, which is convenient for subsequent roll riveting of the radio frequency connector by the roll riveting assembly 3;

[0041] (2) In order to make the outer conical end of the clamp head 5 uniformly contract, so that the clamping area uniformly clamps and fixes the radio frequency connector, the inner wall of the limiting tube 4 is provided with an inner taper, and the large diameter end of the inner taper inner wall is located at the port of the limiting tube 4. When the clamp head 5 is inserted into the limiting tube 4 and an axial movement tendency is applied to it, the outer conical end of the clamp head 5 will be in contact with the inner taper inner wall of the limiting tube 4. Through the design of the inner taper of the inner wall of the limiting tube 4, the outer conical end of the clamp head 5 can be guided by the slope of the inner taper during horizontal left movement.

Then the moving block 9 can be driven to move towards the radio frequency connector to realize roll riveting processing.

[0045] (2) In order to more conveniently drive the moving block 9 to move, a through hole is formed in the base 8, and a rotating shaft 12 is rotatably arranged in the through hole. The rotating shaft 12 is fixedly sleeved with a gear 13, and a tooth surface 14 is arranged on the side of the moving block 9 close to the gear 13 and is in meshing transmission with the gear 13. Meanwhile, a first handle 15 is fixedly arranged on the rotating shaft 12. The rotation of the first handle 15 can drive the rotating shaft 12 and the gear 13 to rotate.
