Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 5As shown, the utility model provides a clamping assembly of a tensile tester, comprising: a clamping tube 1, a clamping column 2, a screw 3 and a connecting seat 4, the clamping tube 1 is a cylindrical structure as a whole, one end of the clamping tube 1 is open and provided with a truncated cone-shaped jacket 11; the clamping column 2 is arranged inside the clamping tube 1, and one end of the clamping column 2 is provided with a truncated cone-shaped clamping platform 21, and the clamping platform 21 and the truncated cone surface of the jacket 11 fit together; the screw 3 is inserted from the unopened end of the clamping tube 1, and a screw hole 23 is provided at the end of the clamping column 2, and the screw 3 is fitted into the screw hole 23; a mounting seat 14 is provided on the outside of the clamping tube 1, the connecting seat 4 is threadedly sleeved on the outside of the mounting seat 14, and a pull ring 42 is provided on the top plate 41 at the end of the connecting seat 4.

[0019] The end of the jacket 11 is provided with an annular extension sleeve 12 , and the end of the clamping platform 21 is correspondingly provided with an extension column 22 ; the top of the screw rod 3 is provided with a torsion block 31 , and the outside of the torsion block 31 is provided with a wheel disc 32 .

[0020] The twist block 31 is connected to the wheel disc 32 to facilitate the user to twist the screw rod 3, thereby driving the clamping column 2 to move. When in use, the extension column 22 is stored in the extension sleeve 12, and the silk thread passes through the gap between the two.

[0021] Among them, a clamping seat 15 is provided at the end of the clamping tube 1, and the screw 3 passes through the clamping seat 15; the clamping seat 15 is provided with an inwardly convex annular clamping edge, and the screw 3 is correspondingly provided with a clamping groove, and the clamping edge is clamped in the clamping groove.

[0022] The screw rod 3 is clamped by the clamping seat 15 and is clamped in the clamping edge through the clamping groove, so that the screw rod 3 can only rotate but cannot move axially, thereby preventing the screw rod 3 from being separated from the clamping tube 1.

[0023] Among them, a strip-shaped friction belt 25 is provided on the outside of the clamping table 21, and the friction belt 25 is distributed in a circular array on the circumferential surface of the clamping table 21; a plurality of groups of annular friction belts 13 are provided inside the jacket 11, and the friction belts 13 are evenly arranged in multiple groups; the friction belts 13 and the friction belts 25 are staggered with each other.

[0024] The interlaced friction belt 1 13 and the friction belt 2 25 can further increase the friction force on the silk thread between the two sets of circular table surfaces, thereby ensuring the clamping strength.

[0025] Among them, a plurality of limiting rods 16 are hoisted in the clamping tube 1, and a limiting groove 24 is provided at the end of the clamping column 2, and the limiting rod 16 and the limiting groove 24 are connected to each other.

[0026] The limiting rod 16 is inserted into the limiting groove 24, which can limit the state of the clamping column 2 so that it can only move axially, better cooperate with the screw rod 3, and avoid deflection.

[0027] The working principle and use process of this utility model:

[0028] The wire to be tested is wound around the clamping column 2, and then wound downwardly around the truncated cone-shaped clamping platform 21 and the extension column 22. The screw 3 is then rotated by twisting the wheel 32. The screw 3 docks with the screw hole 23 and drives the clamping column 2 into the clamping tube 1. During the movement, the truncated cone surfaces of the clamping platform 21 and the jacket 11 gradually come into contact with each other, thereby clamping and fixing the wire. Friction belt 1 13 and friction belt 2 25 are also provided to increase friction, thereby achieving the fixation of the wire. The connecting seat 4 is then installed on the outside of the mounting seat 14 through a threaded structure, and connected to the instrument through the pull ring 42. Tension is applied, and the instrument performs the test.
