[0026] A limiting structure is provided on one side of the third connecting block 17, and the limiting structure includes a fourth connecting block 19. A rotating shaft is rotatably connected to one side of the third connecting block 17, and the rotating shaft is fixedly connected to the fourth connecting block 19. Two second springs 8 are fixedly connected inside the fourth connecting block 19, and the first limiting block 9 is slidably connected inside the fourth connecting block 19. A torsion spring is provided on the outside of the rotating shaft. The elasticity of the second spring 8 itself pushes the first limiting block 9 to the inside of the third connecting block 17, and the sixth sliding block 13 is prevented from sliding down through the fourth connecting block 19. The torsion spring provided on the outside of the rotating shaft makes it possible for the fourth connecting block 19 to rotate to one side of the third connecting block 17 without manually rotating the fourth connecting block 19 after being unlocked, and the elastic force of the torsion spring itself is used to rotate the fourth connecting block 19.

[0027] The interior of one of the third connecting blocks 17 is fixedly connected to the electric telescopic rod body 15, and the outer side of the electric telescopic rod body 15 is fixedly connected to the second connecting block 16.

[0031] When using the device, fix the first connecting block 1 in the main transportation road of the mine. If the device is to be opened, manually pull the two first handles 12, and by pulling the two first handles 12, the two fifth connecting blocks 20 are driven to move, and by the movement of the two fifth connecting blocks 20, the two second limit blocks 10 are driven to move, and by the movement of the two second limit blocks 10, the two third springs 11 are squeezed, and the second limit blocks 10 are moved to the inside of the sixth sliding block 13, and then the sixth sliding block 13 is manually moved upward, and by the movement of the sixth sliding block 13, the X-shaped sliding block 18 is driven to slide on one side of the sixth sliding block 13 and the third sliding block 6, and by manually rotating the fourth connecting block 19, one side of the two first limit blocks 9 is The second connecting block 16 is moved to the inside of the second connecting block 17 by the elasticity of the second springs 8, and the second limiting blocks 9 are pushed to make the second limiting blocks 9 inside the second connecting blocks 17, so as to avoid the two first limiting blocks 9 from moving to the inside of the fourth connecting block 19 due to external factors, so that the sixth sliding block 13 slides down due to gravity, which may hit the transported materials or workers, thereby causing damage to the materials or injuries to the workers, thereby prolonging the working period in the mine. If the device is to be closed, the electric telescopic rod body 15 is started to drive the second connecting block 16 to move, and the second connecting block 16 moves to squeeze the second sliding block 3, and the first sliding block 2 is squeezed by the second sliding block 3. The first sliding block 2 is moved, thereby driving the fourth sliding block 4 to move, and the first sliding block 2 is moved, thereby squeezing the fifth sliding block 7, and the fifth sliding block 7 is moved, thereby squeezing one of the first limit blocks 9 stuck in one of the third connecting blocks 17, so that one of the first limit blocks 9 is squeezed to the inside of the fourth connecting block 19, and the electric telescopic rod body 15 is started, thereby causing the electric telescopic rod body 15 to squeeze another first limit block 9, so that another first limit block 9 is squeezed to the inside of the fourth connecting block 19, and the torsion spring arranged on the outer side of the rotating shaft is used, and the torsion force of the torsion spring is used to rotate the fourth connecting block 19 to one side of the third connecting block 17, and the fourth connecting block 19 is moved, and then manually pulled. The second handle 14 drives the sixth sliding block 13 to move. When the sixth sliding block 13 moves downward, the X-shaped sliding block 18 slides.
