[0039] The extrusion plate C is installed at the end where the external thread of the rotating shaft F is located through two nuts, and the two nuts are respectively matched with the threads of the rotating shaft F. The extrusion plate C is located between the two nuts, and the two nuts clamp the extrusion plate C to achieve the fixation of the extrusion plate C on the rotating shaft F; by adjusting the positions of the two nuts on the rotating shaft F, the height position of the extrusion plate C can be adjusted, so that it has the adaptability to lock different equipment (materials) 5;

[0040] The extrusion plate C is a long strip, and the bottom surfaces of both ends of the length direction are processed into inclined surfaces, so that the extrusion plate C can be rotated onto the pressure surface of the equipment (material) 5 and pressed tightly;

[0041] One end of the driving mechanism is mounted on the frame 4, and the other end is connected to the pin of the rotating seat B. The driving mechanism can perform telescopic movement, thereby driving the rotating seat B to rotate around the axis of the rotating shaft F; the driving mechanism can adopt a telescopic cylinder;

[0042] See attached Figure 4 The roller assembly 2 includes: a roller bracket H, a roller I, a roller bearing J, a gear lever K, a lever bracket L, a lever shaft M, a gear A, a limit block N and a spring O;

[0043] The roller bracket H and the lever bracket L are installed in parallel on the frame 4;

[0044] The central axis of the roller I is installed on the roller support H through the roller bearing J, and the axial direction of the roller I is arranged in the horizontal direction, and one end of the central axis of the roller I extends out of the roller support H; a coaxial limit truncated table is installed on the outside of the roller I to prevent the equipment (materials) 5 from falling off on both sides;

[0045] The gear A is coaxially connected to the end of the central axis of the roller I extending from the roller support H; the gear A adopts triangular teeth;

[0046] The toothed disc lever K is formed in one piece by a first V-shaped rod and a second V-shaped rod with opposite opening directions; wherein, an obtuse angle is formed at the intersection of the first V-shaped rod and the second V-shaped rod, and the tips of the first V-shaped rod and the second V-shaped rod are both obtuse angles; the end of the first V-shaped rod is provided with teeth that cooperate with the gear A; the middle part of the toothed disc lever K (i.e., the intersection of the first V-shaped rod and the second V-shaped rod) is pinned to the lever bracket L through a lever shaft M, and the opening of the first V-shaped rod faces upward, and the opening of the second V-shaped rod faces downward, i.e., the end of the first V-shaped rod is bent upward, and the end of the second V-shaped rod is bent downward; the toothed disc lever K can rotate around the axis of the lever shaft M, and when the end of the first V-shaped rod of the toothed disc lever K rises, the teeth of the end of the first V-shaped rod of the toothed disc lever K can mesh with the gear A; when the rotating seat B rotates to the set position, the end of the second V-shaped rod of the toothed disc lever K is located below the upwardly bent end of the limit plate G, and can fit with the upwardly bent end of the limit plate G;

[0047] The spring O is a tension spring, one end of which is fixed to the frame 4, and the other end is connected to the tip of the first V-shaped rod of the gear lever K. The spring O is used to prevent the end of the second V-shaped rod of the gear lever K from sagging due to its own gravity;

[0048] The limit block N is installed on the lever bracket L and is located below the toothed disc lever K. It is used to limit the toothed disc lever K so that the end of the second V-shaped rod of the toothed disc lever K cannot rise above a set height, that is, it can always be located below the upwardly bent end of the limit plate G, that is, it is always within the adjustment range of the limit plate G; the combination of the spring O and the limit block N is used to make the toothed disc lever K rotate within a set range;

[0049] Working principle: two locking mechanisms are installed in parallel on the frame 4, the equipment (material) 5 to be fixed is located on a plane formed by more than two rollers 1, and the limit round table on the roller 1 is located on both sides of the equipment (material) 5, which is used to prevent the equipment (material) 5 from falling off on both sides;

[0050] When the driving mechanism drives the rotating sleeve B to rotate around the axis of the rotating shaft F, the rotating shaft F also rotates synchronously, thereby driving the extrusion plate C to rotate synchronously. When one end of the extrusion plate C rotates onto the equipment (material) 5, the equipment (material) 5 is pressed tightly onto the roller I;

[0051] At the same time, when the rotating sleeve B rotates to the point where the limit plate G is in contact with the second V-shaped rod end of the gear lever K, the rotating sleeve B continues to rotate, pressing down the second V-shaped rod end of the gear lever K, causing the first V-shaped rod end of the gear lever K to rise, thereby causing the teeth at the first V-shaped rod end to mesh with the gear A. At this time, the roller I cannot rotate, thereby locking the roller I.

[0052] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
