[0019] Further, the first clamping block 8 comprises a lower clamping block 101, an upper clamping block 102, a cooperation through hole 103 and an upper expansion hole 104, the lower clamping block 101 is arranged in cooperation with the upper clamping block 102, engagement teeth are arranged at the connection position of the lower clamping block 101 and the upper clamping block 102, the cooperation through hole 103 is arranged at the left side edge position of the lower clamping block 101, the upper expansion hole 104 is arranged at the upper position of the upper clamping block 102, and a bolt is arranged in the upper expansion hole 104 and cooperates with the lower clamping block 101 to limit. The first clamping block 8 and the second clamping block 9 are used for fixing and limiting the geomembrane, the positions of the first clamping block 8 and the second clamping block 9 correspond to each other, the positions can be adjusted according to actual use, and the geomembrane is fixed and limited.

[0020] Further, the tensile detection component 3 comprises a connecting rod 201, a scale shaft 202, a pressure cylinder 203 and a pressure sensor 204, the right end position of the connecting rod 201 is arranged in cooperation with the first clamping block 8, the left end position of the connecting rod 201 is arranged in cooperation with the scale shaft 202, the left side position of the scale shaft 202 is arranged in cooperation with the pressure cylinder 203, and the left end position of the pressure cylinder 203 is arranged in cooperation with the pressure sensor 204. When the tensile detection component 3 is used for testing the tensile force of the geomembrane, the connecting rod 201 is driven to shrink inward by the pressure cylinder 203, so that the geomembrane is stretched, the force of the pressure cylinder 203 is fed back to the pressure sensor 204 arranged at the rear position, a signal is converted to the controller 5 arranged above, and the subjective judgment ability of the staff is improved.
