Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2The utility model provides a technical solution: a spring-type limiting mechanism, comprising a hand-buckle baffle 1 6, a hand-buckle 7 and a hand-buckle baffle 2 8, the hand-buckle 7 is fixed to the base 1 through the hand-buckle baffle 1 6 and the hand-buckle baffle 2 8, and a mounting cavity 2 is provided in the middle of the base 1, baffle slots 10 are provided on the base 1 on both sides of the mounting cavity 2, and two groups of positioning columns 3 are provided inside the mounting cavity 2, and a spring 4 is installed on the positioning column 3, the mounting cavity 2 is covered with a hand 7 at the upper end, and the hand-buckle baffle 1 6 and the hand-buckle baffle 2 8 pressed on both sides of the hand-buckle 7 are installed in the corresponding baffle slots 10, a limiting protrusion 5 is provided above the hand-buckle baffle 2 8, and the limiting protrusion 5 is fixed to the base 1, and the hand-buckle baffle 2 8 is fixed by a buckle 9 below.

[0019] The buckle 7 includes a vertical plate 71 and a reinforcing plate 74, and baffle grooves 73 are arranged on both sides of the reinforcing plate 74, and the buckle baffle 1 6 and the buckle baffle 2 8 are pressed on the baffle grooves 73 on both sides, and a cross plate 72 is arranged at the bottom of the reinforcing plate 74, and the cross plate 72 is installed in the installation cavity 2.

[0020] The second hand-clasp baffle 8 includes a pressure plate 81, a horizontal baffle 84 and a vertical baffle 83, and the horizontal baffle 84 and the vertical baffle 83 form an L-shaped bending structure. At the same time, a card slot 82 is opened on the pressure plate 81, and the buckle 9 is clamped inside the card slot 82, and the vertical baffle 83 and the horizontal baffle 84 are installed inside the baffle card slot 10.

[0021] The vertical plate 71 provided on the buckle hand 7 is stuck in the gap between the two groups of limiting protrusions 5, and the buckle hand 7 is installed on the installation cavity 2 and is flush with the surface of the limiting protrusions 5.

[0022] The hand-grip baffle plate 1 6 and the hand-grip baffle plate 2 8 have the same structure. Both the hand-grip baffle plate 1 6 and the hand-grip baffle plate 2 8 are formed by metal stamping and bending, and the vertical baffle plate 83 and the pressure plate 81 are parallel.

[0023] The hand 7 is placed above the mounting cavity 2 of the base 1. The hand baffle 1 6 and the hand baffle 2 8 are respectively pressed on the baffle grooves 73 on both sides of the hand 7, and the hand baffle 2 8 is fixed by the buckle 9; the spring 4 is installed on the positioning column 3 and is in a compressed state, ready to provide an upward elastic force for the hand 7. The vertical plate 71 is located in the gap between the two sets of limiting protrusions 5 to ensure that the position of the hand 7 on the mounting cavity 2 is stable and flush with the surface of the limiting protrusion 5. When it is necessary to limit the axial movement of a certain part, the part is placed under the hand 7 and in contact with the cross plate 72. As the downward pressure of the part increases, the hand 7 will be subjected to downward pressure, thereby pressing the hand baffle 1 6 and the hand baffle 2 8. When subjected to pressure, the hand baffle 1 6 and the hand baffle 2 8 will move slightly downward, compressing the spring 4 at the same time to increase the elastic force of the spring.

In the predetermined position; the vertical plate 71 is stuck in the gap between the two groups of limiting protrusions 5, further ensuring that the buckle 7 will not move accidentally; when the limited part needs to be released, the buckle 7 can be operated to overcome the elastic force of the spring 4 to make the buckle 7 rise; as the buckle 7 rises, the buckle baffle 1 6 and the buckle baffle 2 8 will also move accordingly, releasing the limit on the part, and the part can be freely moved out of the installation cavity 2; once the part is moved out, the elastic force of the spring 4 will reset the buckle 7 to the initial position, waiting for the next limiting operation; in the whole process, the elastic force of the spring 4 is the key factor, it automatically adjusts according to the position and pressure of the part to achieve axial limitation of the part.
