The utility model provides a toilet paper toughness testing device which comprises a main body mechanism which comprises a bottom plate, side plates arranged on the two sides of the top of the bottom plate, a first clamping assembly arranged on one side of each side plate, a partition plate arranged on the top of the bottom plate and a second clamping assembly arranged on one side of the partition plate. The first clamping assembly comprises a first hydraulic cylinder arranged on one side of the side plate, a fixing plate arranged at one end of the first hydraulic cylinder, a containing block arranged at the bottom of one side of the fixing plate and an anti-skid pad arranged at the top of the containing block. When the toilet paper clamping and fixing device is used, after the two ends of toilet paper are placed on the placing blocks on one side of the fixing plate respectively, the second hydraulic cylinder drives the clamping blocks to clamp and fix the toilet paper, the friction force with the toilet paper is increased through rubber sheets at the bottoms of the clamping blocks and non-slip mats at the tops of the placing blocks, and the clamping and fixing efficiency is improved; meanwhile, the first hydraulic cylinder drives the toilet paper at the top of the placement block to be stretched for toughness tensile test.

The application discloses a switching device of a phased array antenna testing system and a testing method, relates to the field of phased array antenna testing of satellite communication, and discloses the switching device, which comprises a communication interface, a signal processing assembly and a darkroom testing system. The communication interface is configured with a communication protocol, the darkroom testing system and the phased array antenna follow the communication protocol, and the communication connection between the darkroom testing system and the phased array antenna system is realized through the communication interface. The signal processing assembly stores a testing file for testing the phased array antenna, controls the operation state of the darkroom testing system and switches the working state of the phased array antenna according to the testing file. Meanwhile, the probe of the darkroom testing system is controlled to collect the radio frequency signals of the phased array antenna under different working states according to the switched working state of the phased array antenna, the radio frequency signals are analyzed, and testing data are obtained. The application does not need to stop the work of the two-part system, reduces the testing waiting time, and further improves the testing efficiency.
