[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0021] See also Figure 1-4 The utility model provides an embodiment: a connection mechanism suitable for a stirring reducer, comprising a motor 1, on which a reducer 2 is fixedly mounted.

[0022] The output end of the reducer 2 is provided with a mounting ring 3, a mounting block 4 is movably mounted in the mounting ring 3, a stirring shaft 5 is fixedly mounted on the mounting block 4, a movable groove 6 is provided in the mounting block 4, and a limit block 7 is movably inserted in the movable groove 6;

[0023] A locking mechanism, which is arranged on the mounting block 4 and is used to fix the mounting block 4 on the mounting ring 3;

[0024] The shielding mechanism is arranged on the reducer 2 and is used to shield the mounting ring 3. The device uses a locking mechanism to enable the agitator shaft 5 to be conveniently and stably loaded on the reducer 2. A shielding mechanism is also provided to shield the mounting block 4, thereby increasing the stability of the device when in use;

[0025] Further, the locking mechanism includes a card block 9, which is fixedly mounted on the lower side of the limit block 7. The upper end of the limit block 7 is rounded. A spring 8 is arranged in the movable groove 6. The lower end of the spring 8 is fixedly mounted in the movable groove 6. The upper side of the spring 8 is not connected to the card block 9. A card slot 12 is provided on the mounting ring 3. The position of the card slot 12 corresponds to the position of the limit block 7. The limit block 7 is inserted in the card slot 12. Figure 4 As shown, this structure enables the limit block 7 to be more tightly engaged due to inertia when the stirring shaft 5 rotates, thereby increasing the stability of the equipment during use.

[0026] Furthermore, there are three groups of limit blocks 7, and the distances between the three groups of limit blocks 7 are equal, and the angles between the limit blocks 7 are 120 degrees. Figure 3As shown, this structure enables the mounting block 4 to be mounted on the mounting ring 3 more stably.

[0027] Further, the first damping pad 10 is arranged on the front and rear sides of the lower side of the limit block 7, and the second damping pad 11 is arranged on the slot 12. The first damping pad 10 and one end of the movable slot 6 are against the limit block 7. Figure 4 As shown, this structure enables the limiting block 7 to engage more tightly with the movable groove 6 and the locking groove 12 when it moves to the upper side of the movable groove 6 and the locking groove 12 .

[0028] Further, the shielding mechanism includes a shielding ring 13, which is divided into two halves and can be matched. Two sets of screws 14 are movably arranged on the shielding ring 13, and two sets of screw sleeves 15 are arranged on the front side of the reducer 2. The screws 14 are installed on the screw sleeves 15 through threads, and a sealing gasket 16 is arranged on the opposite side of the shielding ring 13, such as Figure 3 As shown, this structure enables the sealing gasket 16 to shield the mounting block 4, so that the mounting block 4 will not be entangled with debris, thereby increasing the stability of the device during use.

[0029] Furthermore, mounting feet 17 are fixedly installed at the upper and lower ends of the front side of the reducer 2, and fixing holes 18 are arranged on the mounting feet 17. Figure 3 As shown, this structure enables the reducer 2 to be installed more easily.

[0030] Working principle: When in use, press the limit block 7 into the movable groove 6 and then compress the spring 8, so that the mounting block 4 is installed in the mounting ring 3, so that the limit block 7 is engaged in the slot 12 under the rebound of the spring 8, and the first damping pad 10 can use its own resistance and deformation to limit the block 7 so that it can be more stably engaged in the slot 12, and then the shielding ring 13 is combined to wrap the mounting ring 3, and then the screw 14 is screwed into the screw sleeve 15 to fix the shielding ring 13 on the reducer 2 to form a shield for the mounting ring 3. During the rotation process, the limit block 7 will move outward due to inertia to achieve a more stable engagement between the mounting ring 3 and the mounting block 4. The above is the entire working principle of the utility model.
