[0033] The bottom end of the n-shaped frame 3 is welded to the upper end surface of the workbench 1, so that they can be relatively fixed;

[0034] The fixing plate 4 is symmetrically arranged on the outer side wall of the n-shaped frame 3;

[0035] One side wall of the fixing plate 4 is welded to the outer side wall of the n-shaped frame 3, so that the fixing plate 4 can be relatively fixed and the upper end of the electronic tensile testing machine body 2 can be surrounded to protect the upper end of the electronic tensile testing machine body 2.

[0036] A groove 5 is formed in the fixing plate 4;

[0037] The baffle 6 is slidably mounted in the groove 5;

[0038] One end of the baffle 6 slides out of the outside of the groove 5, and can surround the lower end of the electronic tensile testing machine body 2, and can play a protective role on the lower end of the electronic tensile testing machine body 2;

[0039] The driving device is arranged on the fixing plate 4 and is used for driving the baffle plate 6 to slide.

[0040] Specifically, the driving device includes:

[0041] A thread groove 7 is formed in the baffle 6;

[0042] A threaded rod 8, one end of which rotates to penetrate the upper wall of the fixing plate 4, and the other end of which is threadedly connected to the thread groove 7;

[0043] The rotation of the threaded rod 8 can drive the baffle 6 to move, so that one end of the baffle 6 slides out of the outside of the groove 5 or shrinks into the groove 5;

[0044] The first bevel gear 9 is fixedly mounted on the top of the threaded rod 8;

[0045] The fixing block 10 is symmetrically arranged on the upper end surface of the n-shaped frame 3;

[0046] The fixing block 10 is welded to the upper end surface of the n-shaped frame 3 to keep it fixed;

[0047] The rotating rod 11 has two ends that rotate and penetrate a pair of fixed blocks 10;

[0048] There are two second bevel gears 12, which are respectively disposed at both ends of the rotating rod 11. The pair of second bevel gears 12 are respectively meshed and connected with the pair of first bevel gears 9;

[0049] A pair of second bevel gears 12 are respectively welded to the two ends of the rotating rod 11. When the rotating rod 11 rotates, it can drive the pair of second bevel gears 12 to rotate at the same time. The rotation of the pair of second bevel gears 12 can respectively drive the pair of first bevel gears 9 to rotate, so that the pair of first bevel gears 9 can respectively drive the pair of threaded rods 8 to rotate.

[0050] Specifically, it also includes;

[0051] The reducer 13 is arranged on the upper end surface of the n-shaped frame 3;

[0052] The reducer 13 is fixedly mounted on the upper end surface of the n-shaped frame 3 and can be kept fixed;

[0053] The driving member 14 is arranged on the upper end surface of the n-shaped frame 3, and the output end is fixedly connected to the input end of the reducer 13;

[0054] The driving member 14 is a three-phase motor and is fixedly mounted on the upper end surface of the n-shaped frame 3. The rotation of the output end can drive the input end of the reducer 13 to rotate.

[0055] There are two sprockets 15, one sprocket 15 is fixedly mounted on the outer surface of the rotating rod 11, and the other sprocket 15 is fixedly connected to the output end of the reducer 13;

[0056] The chains 16 are respectively meshed and connected with a pair of sprockets 15;

[0057] The output end of the driving member 14 drives the input end of the reducer 13 to rotate. The reducer 13 can reduce the rotation speed of the driving member 14, and then drive a sprocket 15 to rotate through the output end. The rotation of one sprocket 15 can drive the chain 16, so that the other sprocket 15 rotates at the same time and drives the rotating rod 11 to rotate.

[0058] Specifically, a limiting groove 17 is formed on the inner side wall of the groove 5, and a limiting block 18 is fixedly installed on the side wall surface of the baffle 6 which is slidably connected to the limiting groove 17. One end surface of the limiting block 18 is welded to the side wall surface of the baffle 6, so that it can be relatively fixed. At the same time, under the action of the limiting groove 17 and the limiting block 18, the sliding stroke of the baffle 6 can be limited to prevent it from detaching from the groove 5, and at the same time, the baffle 6 can be made more stable when sliding.

[0059] Specifically, a pair of openings are formed in the baffle 6, and tempered glass 19 is fixedly installed in each of the pair of openings. The tempered glass 19 can facilitate observation by the staff when the electronic tensile testing machine body 2 performs a tensile test on the raw materials. At the same time, it can also play a protective role to prevent the raw materials from breaking and causing debris to splash, causing harm to the staff.

[0060] Working principle: First, the staff fixes the raw materials that need to be subjected to the tensile test to the electronic tensile testing machine body 2. At this time, the staff starts the driving member 14. The output end of the driving member 14 drives the input end of the reducer 13 to rotate. The reducer 13 can reduce the rotation speed of the driving member 14, and then drive a sprocket 15 to rotate from the output end. The rotation of one sprocket 15 can drive the chain 16, so that the other sprocket 15 rotates at the same time and drives the rotating rod 11 to rotate. At this time, the rotation of the rotating rod 11 can simultaneously drive a pair of second bevel gears 12 to rotate. The rotation of the pair of second bevel gears 12 can respectively drive a pair of first bevel gears 9 to rotate, so that the pair of first bevel gears 9 can respectively drive a pair of threaded rods 8 to rotate. The rotation of the threaded rod 8 can drive the baffle 6 to move, so that the baffle 6 slides out of the groove 5, and the lower end of the electronic tensile testing machine body 2 is protected to prevent the raw materials from breaking and causing debris to splash, causing harm to the staff. At the same time, the tempered glass 19 can facilitate the staff to observe when the electronic tensile testing machine body 2 performs a tensile test on the raw materials, bringing convenience to people.
