A first motor 12 is arranged between the two groups of guide rods 4 on the base 1, and a transmission assembly is arranged between the first motor 12 and the platform 5.

The transmission assembly comprises a transmission disc 11 and a connecting rod 10, a round mandrel 20 and an eccentric shaft 19 are arranged on the transmission disc 11, the round mandrel 20 is connected with a rotating shaft of the first motor 12, the eccentric shaft 19 is rotatably connected with one end of the connecting rod 10, and the other end of the connecting rod 10 is rotatably connected with an ear seat 25 at the lower end of the platform 5.

The working steps are as follows:

firstly, a first motor 12 drives a transmission disc 11 to rotate, and the platform 5 is driven to reciprocate up and down along a guide rod 4 under the matching of the transmission disc 11 and a connecting rod 10;

next, referring to fig. 1, when the platform 5 is in a falling state, the cord fabric 2 is pulled to the upper side of the boss 6 of the platform 5 manually or by a motor and is lapped on the two sets of positioning components;

next, referring to fig. 2, when the platform 5 is in a rising state, the upper end surfaces of the sliders 22 of the two sets of positioning components are matched with the lower end surface of the cross beam 3 to press and fix the cord fabric 2, and then when the platform 5 rises continuously, the springs 23 of the positioning components are compressed, and at the moment, the arched convex parts 6 rise continuously and support and stretch the cord fabric 2 upwards;
