The air pressure connected to the pneumatic control body 1 will be connected to the inside of the jig track body 101. At the same time, the slide rail fixing part 2 is symmetrically installed at the bottom of the jig track body 101. When the jig track body 101 is connected to the air pressure, the air pressure will force the slide rail fixing part 2 to slide horizontally in the left and right directions at the bottom of the jig track body 101. The shape of the slide rail fixing part 2 is "T" shaped, and the vertical position of the slide rail fixing part 2 is responsible for installing and removing the replaceable fixture 201.

[0024] Specifically, an air inlet 102 is provided on one side of the air pressure control body 1 , and a plurality of fixing screw holes 103 are provided on the top of the air pressure control body 1 .

[0025] It should be noted that an air inlet 102 is provided at the top of one side of the air pressure control body 1. The air inlet 102 allows the connected air pressure device to input the air pressure into the air pressure control body 1 to complete the left and right offset of the slide rail fixing part 2. The screw hole 103 is fixed at the top of the air pressure control body 1, and the air pressure control body 1 is fixed to the rising arm of the tensile testing machine by screws to facilitate the tensile testing of the product.

[0026] Specifically, a pneumatic slide rail 104 is provided at the bottom end of the jig rail body 101, and a slider structure 203 is provided at the top end of multiple slide rail fixing parts 2. The top end of the slide rail fixing part 2 is fixedly connected to the bottom end of the slider structure 203, and the outer wall of the slider structure 203 is socketed with the inner wall of the pneumatic slide rail 104.

[0027] It should be noted that the pneumatic slide rail 104 is arranged at the bottom end of the jig rail body 101, and the route of the pneumatic slide rail 104 is connected to the two ends of the jig rail body 101. At the same time, the shape of the slider structure 203 of the slide rail fixing part 2 fits the inner wall of the pneumatic slide rail 104, so that the slider structure 203 can slide horizontally on the inner wall of the pneumatic slide rail 104, and the slider structure 203 drives the slide rail fixing part 2 to slide horizontally in the left and right directions.

[0028] Specifically, a plurality of first fixing holes 204 are provided on both sides of the slide rail fixing member 2 , and a second fixing hole 205 is provided on both sides of the replaceable fixture 201 .

[0029] It should be noted that when the slide rail fixing part 2 and the replaceable fixture 201 are installed, the positions of the first fixing hole 204 and the second fixing hole 205 are overlapped with each other, and bolts are inserted through the inner walls of the first fixing hole 204 and the second fixing hole 205 to connect them. After the connection is completed, the slide rail fixing part 2 and the replaceable fixture 201 are fixed. At the same time, the slide rail fixing part 2 and the replaceable fixture 201 can be disassembled by bolts. After disassembly, different replaceable fixtures 201 can be replaced for testing according to the measurement of the product.

[0030] Specifically, a clamping block 3 is provided at one end of the multiple clamping rods 202 away from the slide rail fixing member 2, and a product fixing member 301 is provided at the bottom end of the clamping block 3.

[0031] It should be noted that the bottom end of the replaceable clamp 201 is symmetrically installed with a clamp rod 202, and circular holes corresponding to the clamp rod 202 are provided at both ends of the clamp block 3 facing the clamp rod 202. When the replaceable clamp 201 is offset left and right by air pressure, the replaceable clamp 201 drives the clamp to offset toward the circular hole and is inserted into the circular hole to fix the clamp block 3. A slide rail is horizontally provided at the top of the product fixing part 301, and the fixed slider 303 at the bottom end of the clamp block 3 can be inserted into the slide rail to achieve horizontal sliding. The fixation and disassembly between the product fixing part 301 is achieved through the fixed slider 303. The horizontal sliding in the left and right directions is also achieved between the bottom end of the product fixing part 301 and the tensile machine slide rail 302 through insertion.

[0032] Working principle of this utility model:

[0033] The specific operation is that first, the top of the air pressure control body 1 needs to be fixed to the detection device through the fixing screw hole 103, and then a suitable replaceable fixture 201 is selected, and the replaceable fixture 201 and the slide rail fixing part 2 are fixed through the first fixing hole 204 and the second fixing hole 205 to complete the assembly of the fixture. The air pressure enters the interior of the air pressure control body 1 through the air inlet 102, and the air pressure control body 1 then transmits the air pressure to the pneumatic slide rail 104. The slide rail fixing part 2 is cheap under the action of the air pressure inside the pneumatic slide rail 104. When the slide rail fixing part 2 deviates left and right, it drives the replaceable fixture 201, and the clamping rod 202 at the bottom end of the replaceable fixture 201 deviates and clamps toward the clamping block 3. The clamping block 3 is fixed to the product fixing part 301 through the fixed slider 303. After the fixation is completed, a tensile test is performed.
