The pulley 13 is movably arranged in the No. 2 connecting block 5. The two corresponding pulleys 13 at the front and rear are connected by a sleeved belt, and the belt is movably arranged in the clamping plate 3. Through the cooperation of the pulley 13 and the belt, the synchronous rotation of the two corresponding threaded rods 6 at the front and rear can be realized, which is not only more conducive to the convenient clamping operation of the three-proof cloth, but also can prevent the clamping plate 3 from tilting and getting stuck;

[0029] A double-axis motor 7, wherein the double-axis motor 7 is fixedly arranged in the base 1, and screws 9 are fixedly arranged on the two output shafts of the double-axis motor 7, one end of the screw 9 is screwed on the inner wall of the rectangular groove through a bearing, and the screw 9 is screwed through the moving plate 2 through a thread, and the threads of the two screws 9 are arranged in opposite directions;

[0030] The protective cover 10 is hingedly connected to the upper rear part of the base 1. The base 1 is provided with an active closing mechanism 11 that cooperates with the protective cover 10. The protective cover 10 is made of a transparent acrylic material, which can not only provide protection for the staff, but also facilitate the staff to observe the stretching state of the three-proof cloth;

[0031] The active closing mechanism 11 comprises:

[0032] A driving rod 11-1, wherein the driving rod 11-1 is two and movably abuts against each other on the side walls of the two movable plates 2, and the driving rod 11-1 is movably inserted into a control groove 15 opened on the side wall of the rectangular groove, and the two driving rods 11-1 are connected by a No. 1 spring 11-2, and the No. 1 spring 11-2 is arranged in a movable groove 8 opened between the two control grooves 15;

[0033] A control board 11-3, wherein the control board 11-3 is movably arranged in the movable groove 8, a plurality of No. 2 springs 11-4 are fixedly arranged at the lower part of the control board 11-3, and the lower end of the No. 2 spring 11-4 is connected to the inner bottom wall of the movable groove 8, and movable boards 11-5 are rotatably arranged on the left and right sides of the control board 11-3 through shafts and bearings, and the movable boards 11-5 are movably arranged on the left and right sides of the base 1, and two guide rods 12 are fixedly arranged in the movable groove 8 by bolts, and the guide rods 12 are movably arranged on the control board 11-3, and the guide rods 12 can provide guidance for the control board 11-3 to move up and down;

The control plate 11-3 drives the movable plate 11-5 to move upward, and then the protective cover 10 can be manually flipped over from the base 1 and opened again. At this time, the movable rod 11-6 can also move in the guide groove of the movable plate 11-5 as the protective cover 10 is flipped, and drive the movable plate 11-5 to flip to the rear side by a certain angle.

[0036] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0037] 1. The protective cover 10 can be used to provide protection and shielding during the tensile strength test of the three-proof cloth to prevent the three-proof cloth from breaking due to the tensile force exceeding its own bearing limit, causing accidental injury to the staff.
