[0043] As an implementation method in this embodiment, in order to meet the pull-out test requirements of various nylon insulation strips, such as Figure 3 , Figure 5 , Figure 8 As shown, a groove is provided at the bottom of the clamping block 21, and the groove is adapted to the placement table 20.

[0046] Working principle of the utility model: when conducting the nylon insulation strip pulling test, since there is a gap between the pressure plate 22 and the placement table 20 for placing the nylon insulation strip, the buckle rod 40 and the buckle 14 are not fastened, the buckle rod 40 can be pushed forward to disengage from the buckle 14, and then the synchronization rod 4 is lifted upward, and the two groups of clamping blocks 21 are lifted up at the same time through the synchronization sleeve 24 to expose the placement table 20, and then the two ends of the nylon insulation strip sample are placed on the placement table 20, and then the synchronization rod 4 is moved to drive the two groups of clamping blocks 21 to fall at the same time, and the pressure plate 22 is pressed on the two ends of the nylon insulation strip sample. Since the nylon insulation strip can be deformed to a certain extent, the buckle rod 40 is pressed downward to buckle the buckle rod 40 and the buckle 14 to limit the position. At this time, the pressure plate 22 The two ends of the nylon insulation strip sample are clamped with the placement table 20, and the nylon insulation strip sample is fixed on the base 1. Then the limit button 7 is in a position perpendicular to the radial direction of the axis of the screw 3. Under the push of the reset spring 8, the ratchet 61 of the slider 6 is engaged with the ratchet 31, and the handle 51 is used to rotate the hoop 5 to drive the screw 3 to rotate forward. After rotating a certain angle, the handle 51 is used to rotate the hoop 5 in the reverse direction. When the hoop 5 rotates in the reverse direction, the ratchet 61 is squeezed by the ratchet 31 and automatically retracts into the adjusting sleeve 50. When the hoop 5 rotates forward again, the ratchet 61 is engaged with the ratchet 31 again, and the screw 3 is driven to rotate through the ratchet 31. In this way, the handle 51 is used to drive the screw 3 to rotate forward, which is convenient for applying torque, and the screw 3 rotates and is The lead screw nut 13 drives the axial movement, thereby driving the clamping seat 2 connected to the lead screw 3 to move along the guide rail 12, stretching the nylon insulation strip sample, and pulling the clamping seat 2 on the left side. The tension pressure sensor 11 detects the tension in this process and displays the result on the display panel 10. The lead screw 3 is continuously rotated until the nylon insulation strip sample is broken. The maximum tensile force detected is displayed on the display panel 10, and the pulling test is completed. During the pulling process, the synchronous sleeve 24 slides along the synchronous rod 4, and the clamping block 21 always cooperates with the placement table 20 to clamp and fix the nylon insulation strip sample when moving with the clamping seat 2. After the pulling test is completed, the buckle rod 40 is disengaged from the buckle 14, and the clamping block 21 is lifted to break the sample. The cracked nylon heat insulation strip sample is removed, and then the limit button 7 is rotated to the radial position with the axis of the lead screw 3, and the limit block 70 rotates accordingly, and the slider 6 is pushed through the limit groove 60, so that the ratchet 61 and the ratchet wheel 31 remain disengaged, and the positioning groove 62 helps the limit block 70 to be positioned and matched with the limit groove 60, and the positioning block 52 cooperates with the positioning plate 71 to limit the rotation angle of the limit block 70, which can improve the convenience of using the limit button 7 and is conducive to effectively limiting the slider 6. At this time, the hoop 5 can rotate freely on the ring groove, and then the handle 30 can be used to quickly rotate the lead screw 3 in the opposite direction to reset the clamping seat 2. After the reset is completed, the limit button 7 is rotated to the initial position, and the nylon heat insulation strip pulling test can be carried out again;Since there are many types of nylon insulation strips with different thicknesses, rotating the adjustment bolt 23 can drive the pressing plate 22 to rise and fall, so as to clamp nylon insulation strips of different thicknesses and meet various pull-out test requirements. The guide bar 25 guides the pressing plate 22 so that the pressure of the pressing plate 22 and the placing table 20 are uniform and the clamping is stable. ;
