Two stress sliding blocks 17 are slidably connected inside protective shell 3 through control position track 16, the purpose of setting control position track 16 is to effectively ensure the stability of two stress sliding blocks 17 and clearly define the moving directions of two stress sliding blocks 17.
[0021] As Figure 1 , Figure 3 shown, the top of the force block 17 is fixedly connected with the L-shaped clamping plate 18, the force block 17 and the L-shaped clamping plate 18 keep the linkage effect, the lower end of the I-shaped steel beam 2 is placed between the two L-shaped clamping plates 18, and under the action of the two L-shaped clamping plates 18, the I-shaped steel beam 2 can be effectively clamped, so that the protective shell 3 is firmly suspended directly below the I-shaped steel beam 2, and the two ends of the bidirectional screw rod 15 are rotatably connected to the inner wall of the protective shell 3. The protective shell 3 supports the bidirectional screw rod 15 and applies a control effect, so that the bidirectional screw rod 15 can rotate in place in the protective shell 3.
