[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0021] according to Figure 1-3 As shown, a rubber mixer includes a motor 1, a mixing blade, a transmission assembly, a column 3, support bases 9, and a cantilever 4. The cantilever 4 is movably connected to the top of the column 3 via bearings. The motor 1 is installed at one end of the cantilever 4, and the mixing blade is installed at the other end. The transmission assembly is installed inside the hollow cantilever 4, and the kinetic energy of the motor 1 is transmitted to the mixing blade through the transmission assembly. A limit mechanism 5 is provided at the connection between the column 3 and the cantilever 4. The cantilever 4 rotates around the column 3, allowing the mixing blade installed at one end of the cantilever 4 to flexibly change its orientation. One or more support bases 9 are provided for use with the mixing blade. When multiple support bases are provided, they are distributed in an arc shape around the column 3.

[0022] according to Figure 1-3 As shown, the limiting mechanism 5 includes a reel 51, a return spring 52, a movable disc 53, a reference disc 54, a pull rope 55, and a limiting assembly 56. The reel 51 is movably connected to the column 3. A portion of the pull rope 55 is wound around the reel 51, with one end connected to the limiting assembly 56 and the other end extending outside the column 3, where a handle 6 is installed. The return spring 52 is mounted on the reel 51 for rotating and resetting the reel 51. The reference disc 54 is fixed to the top of the column 3, and the movable disc 53 is fixed to the bottom of the cantilever 4. The bottom of the movable disc 53 has a slot 531 for engaging with the limiting assembly 56. The limiting assembly 56 is mounted on the reference disc 54 for engaging with the slot 531. It should be noted that the return spring 52 is a variable-force spring, with its inner end connected to the reel 51 and its outer end connected to the column 3.

[0023] according to Figure 1-3As shown, pulling the handle 6 selects the reel 51, and the pull rope 55 connected to one end of the handle 6 changes from a wound state to an unwound state, while the pull rope 55 connected to the limiting component 56 changes from an unwound state to a wound state, thereby pulling the limiting component 56 to separate from the slot 531. At this time, the cantilever 4 can rotate freely. After the cantilever 4 can rotate, the handle 6 is released, and the reel 51 moves in the opposite direction under the action of the variable force spring. The limiting component 56 also abuts against the lower end face of the movable plate 53. The lower end face of the movable plate 53 has multiple positioning grooves 532, which are evenly distributed circumferentially around the column 3. The positioning grooves 532 and the slot 531 are on the same circumference. The depth of the positioning groove 532 is less than the depth of the slot 531. When the cantilever 4 is rotated, the limiting component 56 will insert into the positioning groove 532, thereby producing a jerky feeling, which serves as a certain prompt to the operator.

[0024] according to Figure 1-3 As shown, the limiting component 56 includes a locking pin 561, a compression spring 562, and an end cap 563. A blind groove 541 is provided at the top of the reference plate 54, and a through hole for the locking pin 561 to pass through is provided at the bottom of the blind groove 541. The end cap 563 is fixedly connected to the locking pin 561. The compression spring 562 is sleeved on the locking pin 561, with one end abutting against the end cap 563 and the other end abutting against the bottom of the blind groove 541.

[0025] Figure 2 With the locking pin 561 engaged with the locking slot 531, the pull rope 55 at one end of the connecting handle 6 is wound around the reel 51. Figure 3 With the locking pin 561 separated from the slot 531, the pull rope 55 connecting one end of the locking pin 561 is wound around the reel 51.

[0026] according to Figure 1-3 As shown, the column 3 is provided with a telescopic fixing mechanism 7 for fixing the barrel. The telescopic fixing mechanism 7 includes a connecting rod 71, a telescopic shaft 72 and a fixing seat 73. The connecting rod 71 is fixedly connected to the column 3 near the middle of its length. Both ends of the connecting rod 71 are provided with sleeves 711. There are two telescopic shafts 72, which are inserted into the two sleeves 711 respectively. The ends of the two telescopic shafts 72 opposite to the stirring paddle are fixed together on the fixing seat 73. The fixing seat 73 is provided with locking pins 731 for fixing the barrel. The cylinder walls of the two sleeves 711 are threaded with locking bolts 8.

[0027] according to Figure 1-3 As shown, the support base 9 includes a frame made of metal and feet fixed around the bottom of the frame. The empty area of ​​the frame is filled with pads made of plastic or wood. In this invention, the pads are preferably made of wear-resistant solid wood.

[0028] according to Figure 1-3As shown, the barrel is placed on the support base 9, and then the barrel is fixedly connected to the fixing base 73. The side of the fixing base 73 opposite to the barrel is set in a C-shape, and the barrel is placed in the C-shaped area. Finally, the buckle on the barrel is connected to the locking pin 731. The buckle structure that can achieve the connection is quite common and will not be described in detail in this utility model. Because the center distance of the support base 9 from the column 3 is based on the placement of the mixing paddle, therefore...

[0029] After placing the bucket, adjust the fixing seat 73 to be close to the bucket. The adjustment method is to first loosen the locking bolt 8, move the telescopic shaft 72, and after the fixing seat 73 is in the correct position, tighten the locking bolt 8 again. It should be noted that the support seat 9 can be flexibly set. A suitable size can be selected according to the volume of the bucket, or the support seat 9 can be omitted.
