[0026] Furthermore, a test bench 101 is provided on one side of the machine body 1 , a detection seat 3 is provided in the middle of the test bench 101 , and U-shaped pressure strips 4 are rotatably mounted on both ends of one side of the test bench 101 through a rotating seat 6 .

[0027] Furthermore, slots are provided at both ends of one side of the test bench 101, a rotating seat 6 is rotatably installed in the slot, a return torsion spring 61 is provided between the rotating seat 6 and the rotating end of the slot, and a U-shaped pressure strip 4 is fixedly installed on one side of the rotating seat 6, and the U-shaped pressure strip 4 is in contact with the surface of the test bench 101.

[0028] Furthermore, a plurality of pressing sheets 41 are provided on the rod bodies on both sides of the U-shaped pressure strip 4 .

[0029] Furthermore, a limiting frame 9 is provided at one side inside the machine body 1 , a connecting frame 10 is installed inside the limiting frame 9 for limiting movement, and both sides of the connecting frame 10 are slidingly installed in limiting grooves 91 opened on both sides of the limiting frame 9 .

[0030] Furthermore, limit seats 14 are installed on both sides of the bottom of the connecting block 11 and both sides of the top of the top block 71, and a limit rod 13 is fixedly installed between the limit seats 14. The top block 71 is slidably installed on the upper limit of the limit rod 13, and a trigger block 121 is installed on the top of the top block 71.

[0031] Furthermore, a detection groove 31 is provided in the middle of the detection seat 3 , and the detection groove 31 is matched with the push rod 7 .

[0032] Furthermore, side grooves 72 are provided on both sides of the push rod 7, and the lifting platform 5 is installed in the side grooves 72 by limiting sliding through the clamping blocks 51. A notch is provided in the middle of the lifting platform 5, and the push rod 7 passes through the notch, and the push rod 7 is retracted into the horizontal plane of the bottom wall of the lifting platform 5.

[0033] In this embodiment, the U-shaped pressure strip 4 at the test bench 101 is opened, and the leather piece to be tested is placed on the test bench 101 so that the leather piece covers the test seat 3 and the test groove 31. At this time, the U-shaped pressure strip 4 is released, and the U-shaped pressure strip 4 is reset under the reset force of the reset torsion spring 61, and presses the outer side of the leather piece to fix it. In actual use, the control panel 2 provided in the body 1 controls the electrical components connected to the inside of the body 1 through electrical signals, and at the same time, the control panel 2 controls the electric push rod 8 inside the body 1 to extend and retract, and its telescopic rod is connected to the connecting frame 10, and the connecting frame 10 drives the connecting block 11, the top block 71, the top rod 7, and the lifting platform 5 to move downward.

When it continues to slide to the limit seat 14 set on the top of the limit rod 13, the pressure sensing module 12 contacts the trigger block 121 on the top block 71, and in the process of the electric push rod 8 continuously pushing downward, the reaction force generated by the push rod 7 and the leather top pressure is converted into the pressure change value of the pressure sensing module 12 and the trigger block 121, and the pressure sensing module 12 visualizes the pressure change electrical signal and inputs it on the control panel 2.

[0034] During the pressing test of the push rod 7 , the push rod 7 presses the leather on the detection seat 3 , and under the pushing action of the electric push rod 8 , the push rod 7 fits into the detection groove 31 .

[0035] In actual application, the trigger block 121 does not contact the pressure sensing module 12 in a natural state.

[0036] In the utility model, the leather to be tested is fixed on the test bench through the setting of the test bench 101, the detection seat 3 and the U-shaped pressure strip 4, and the push rod is driven downward through the control panel 2 to press the leather surface to convert the pressure change into a visible electrical signal. Compared with the traditional manual trigger test detection method, the measurement value of this device is more accurate, and at the same time, the setting of the electric push rod 8 and the control panel 2 effectively reduces the work intensity. It is easy to use, fast to measure, and improves the detection efficiency.
