Specifically, before the telescopic horizontal protection rod 5 is installed, the third compression spring 531 is in a compression state, one end of the positioning rod 542 extends out of the positioning hole, the fourth compression spring 542 is in a natural unstressed state, at this time, the whole length of the protection rod is far smaller than the width between the two vertical rods, the positioning rod 542 is pressed to enable the positioning rod 542 to enter the sleeve 51, the fourth compression spring 541 is compressed, then the telescopic rod 52 extends out outwards under the action of the third compression spring 531, at this time, the whole length of the protection rod is far larger than the width between the two vertical rods, then the end of the telescopic rod 52 far away from the sleeve 51 is placed into the jack 6 on the second vertical rod 121, then the whole protection rod is close to the second vertical rod 121 to adjust the whole length of the protection rod, the end part of the telescopic rod 52 acts on the inner wall of the second vertical rod 121, the reaction force of the inner wall acts on the telescopic rod, make it retract to sleeve 51 is interior, when length adjustment is in good time, the jack 6 on first montant 111 just can be put into to the one end that sleeve 51 kept away from telescopic link 52, then let go, sleeve 51 and telescopic link 52 then self-adaptation under the effect of third compression spring 531 adjusts, sleeve 51 and telescopic link 52 are located that the one end of jack 6 supports corresponding inner wall respectively, telescopic horizontal protection pole 5's installation is accomplished promptly, at this moment, locating lever 542 still is located sleeve 51.

The specific process of disassembling is as follows:

firstly, be close to the whole guard bar towards second montant 121, the tip of telescopic link 52 is used in on second montant 121 inner wall, the reaction force of inner wall then is used in on telescopic link 52, make it retract to sleeve 51 in, locating lever 542 follows telescopic link 52 and moves and is close to locating hole 10 gradually, when locating lever 542 moved to locating hole 10 department, fourth compression spring 541 acted in make locating lever 542 outwards pop out from locating hole 10, the one end that sleeve 51 is located jack 6 at this moment has left jack 6 completely, and the whole length of guard bar is far less than the width between two montants, then remove the guard bar whole towards first montant 111, make the one end that telescopic link 52 is located jack 6 leave jack 6, telescopic horizontal guard bar 5 can be dismantled by whole.

Further definition of the first L-shaped fixing lever 21 and the second L-shaped fixing lever 22:

the short ends of the first L-shaped fixing rod 21 and the second L-shaped fixing rod 22, which are in contact with the wall, are provided with clips 16. In order to further reduce the damage to the concrete structures on the two sides of the opening, the clamping pieces 16 are arranged at the short ends of the two L-shaped fixing rods, which are in contact with the wall, and the clamping pieces 16 increase the contact area between the fixing component 2 and the wall, so that when the fixing component 2 is clamped on the wall, the pressure applied to the wall is smaller under the action of the clamping pieces 16, and the damage to the concrete structures on the two sides of the wall by the fixing component 2 can be reduced to the greatest extent.
