Although this method can realize the movement of the bracket, it can only move one bracket at a time, which is inefficient and increases the construction time. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0020] A quick withdrawal support for a coal mine fully mechanized working face comprises: a base 1 with a main baffle 2 arranged on the top, and a back plate 3 and a front plate 4 are rotatably mounted on both ends of the main baffle 2, and a resistance plate 5 is rotatably mounted on the other end of the front plate 4, and an angle adjustment mechanism 6 and a first driving mechanism 7 are also included, wherein the angle adjustment mechanism 6 is used to mount the main baffle 2 on the surface of the base 1 and adjust the inclination angle of the main baffle 2, and the first driving mechanism 7 is used to drive the back plate 3, the front plate 4, and the resistance plate 5 to rotate respectively, and a limited position bin 8 is fixedly mounted on one side of the base 1, and a limited position block 9 is arranged on the other side of the base 1, and a user can control one of the bases 1 through a lifting mechanism 10 The limiting block 9 on one side is inserted into the inner wall of the limiting bin 8 on the surface of the other base 1, so as to realize the docking of the bases 1 of the two devices. A connecting ring 11 is fixedly installed on the surface of the base 1, wherein the main components of the angle adjustment mechanism 6 are: a first rotating rod 601 rotatably installed on the surface of the base 1, and the other end of the first rotating rod 601 is rotatably installed with a second rotating rod 602, and the other end of the second rotating rod 602 is rotatably installed on the surface of the main baffle 2. The user drives the two first multi-stage hydraulic rods 603 rotatably installed on the surface of the base 1 to extend and retract, so as to drive the main baffle 2 rotatably installed at the other end thereof to move, thereby realizing the inclination angle of the main baffle 2. The first driving mechanism 7 is mainly composed of: two second multi-stage hydraulic rods 701 which are both rotatably mounted on the top of the base 1, and the other ends of the two second multi-stage hydraulic rods 701 are both rotatably mounted on the surface of the back plate 3, so the user controls the extension and retraction of the two second multi-stage hydraulic rods 701 to adjust the angle of the back plate 3, the surfaces of the main baffle 2 and the front end plate 4 are both rotatably mounted with two driving hydraulic rods 702, and the other ends of the plurality of driving hydraulic rods 702 are respectively rotatably mounted on the surfaces of the front end plate 4 and the contact plate 5, so the user can control the extension and retraction of the plurality of driving hydraulic rods 702 to control the angle of the front end plate 4 and the contact plate 5, respectively, wherein the lifting mechanism 7 is a plurality of driving hydraulic rods 702.
