The clamping rod 208 moves in the direction away from the slot 203, and after completely away from the slot 203, the pull plate 204 can be moved, so that the pull plate 204 rotates around the rotating block 202. The outside of the pull plate 204 is fixedly connected with an anti-slip sleeve 214, and two arc grooves 205 are provided on the inner side of the pull plate 204. The anti-slip sleeve 214 has the effect of increasing friction. The arc groove 205 is slidably connected with an arc plate 206, and the side of the two arc plates 206 close to each other is fixedly connected to the tester body 1. The effect of the arc plate 206 sliding in the arc groove 205 is achieved. One end of the clamping rod 208 is fixedly connected with a pull block 210, and one side of the pull block 210 is fixedly connected with two rubber pads 212. The effect of the rubber pad 212 increasing friction is achieved. The arc surface of the clamping rod 208 is covered with a spring 213, and the two ends of the spring 213 are respectively fixedly connected to the pull block 210 and the L-shaped block 209. The effect of the pull block 210 moving to drive the spring 213 to stretch or contract is achieved. One side of the rubber pad 212 is fixedly connected with a telescopic rod 211, and one end of the four telescopic rods 211 is fixedly connected to the tester body 1. The rubber pad 212 moves to drive the telescopic rod 211 to stretch or contract.

[0035] Reference Figure 4 As shown, in this embodiment: the protective device 3 includes two fixed plates 33, one side of the fixed plate 33 is fixedly connected with two elastic sheets 31, and one end of the four elastic sheets 31 is fixedly connected to the tester body 1. The effect of the fixed plate 33 moving to drive the elastic sheets 31 to stretch or contract is achieved.

The effect of the sponge pad 35 being able to absorb a certain amount of pressure when it is subjected to pressure is achieved.

[0036] Working principle: through the fixing device 2, when the ONT tester needs to be supported, the operator first holds the tester body 1 for use. During the test, the pull block 210 is pulled in the direction away from the card slot 203. The pull block 210 is subjected to the tension and drives the clamping rod 208 to move in the direction away from the card slot 203. At this time, the spring 213 is in a stretched state. When the clamping rod 208 is completely away from the card slot 203, the pull plate 204 can be moved to rotate around the rotating block 202 as the center. After rotating a certain angle and contacting the surface of the placement location, the pulled pull block 210 is released. At this time, the spring 213 rebounds and drives the clamping rod 208 to approach the card slot 203 until it contacts the card slot 203, so that the tester body 1 can be supported. Through the fixing device 2, the problem of a traditional portable OTN tester that is inconvenient to support and place the tester body 1 when the user does not hold the tester body 1 is solved.

[0037] By means of the protective device 3, when it is necessary to prevent the ONT tester from falling and bumping, and the impact force causing damage to the internal parts, the operator first assembles the protective device 3 on the outside of the tester body 1. When the tester body 1 falls, the impact force can be reduced to a certain extent by squeezing or stretching the elastic sheet 31. The sponge pad 35 can also reduce a certain impact force after contacting the tester body 1, thereby reducing the impact force generated when the tester body 1 is bumped. By means of the protective device 3, the problem of a traditional portable OTN tester that cannot reduce the damage to the internal parts caused by the impact force of the tester body 1 due to the lack of protective components assembled on the outside is solved.
