[0036] The twist foot main seat 5 is fixedly connected to the fixing seat 4, and a positioning column 51 for fixing the rotor 1 is arranged on the twist foot main seat 5, and a rotatable turntable 6 is arranged on the twist foot main seat 5. Figure 3As shown, the twist foot main seat 5 includes a twist foot upper seat 52 and a twist foot lower seat 53, four groups of bearing columns 54 are arranged between the twist foot upper seat 52 and the twist foot lower seat 53, and the bearing columns 54 are respectively arranged at the four corners of the twist foot upper seat 52 and the twist foot lower seat 53, and each of the bearing columns 54 is provided with a first bearing 55 that abuts against the side edge of the turntable 6. The turntable 6 of this embodiment is arranged between the twist foot upper seat 52 and the twist foot lower seat 53, and the four side edges of the turntable 6 abut against the first bearing 55. The turntable 6 is supported by the four groups of first bearings 55. It plays the role of limiting and positioning. At the same time, the twist foot upper seat 52 and the twist foot lower seat 53 also limit the up and down directions of the turntable 6, so that the turntable 6 rotates in place and the whole will not deviate. The above-mentioned positioning column 51 is arranged on the twist foot upper seat 52. In order to enable the positioning column 51 to cooperate with the rotor 1, this embodiment is through the twist foot upper seat 52 and the twist foot lower seat 53 to open the sixth through hole 521 and the second through hole 531 of the position matching, and the turntable 6 is provided with a first through hole 61 of the same position matching, so that the positioning column 51 can pass through the center of the above-mentioned component.

[0037] like Figure 3 As shown, a plurality of twist foot assemblies 7 are detachably connected to the turntable 6, and the number of the twist foot assemblies 7 is set according to the number of T-shaped fixed feet 14 on the rotor 1, such as four, six, etc., without limitation. The setting angle of the twist foot assemblies 7 is also adjusted according to the actual sample. For example, in this embodiment, a total of six groups of twist foot assemblies 7 are set, and each group of twist foot assemblies 7 is set at 60° on the turntable 6; one side of the twist foot assembly 7 is connected to the turntable 6, and the other side of the twist foot assembly 7 is provided with a button needle 71, and the button needle 71 passes through the first through hole 61 and extends to the bottom of the twist foot main seat 5, and a twist foot groove 711 is provided at the position where the button needle 71 is placed below the twist foot main seat 5, specifically: Figure 4 and Figure 5 As shown, the twist foot assembly 7 includes a button pin seat 72 and a button pin 71 fixed to the button pin seat 72, the twist foot groove 711 is arranged at the end of the button pin 71, the side wings of the button pin seat 72 extend outward to form a first mounting portion 721, and a second bearing 722 is arranged on the first mounting portion 721. In order to realize the movable connection between the first mounting portion 721 and the rotating disk 6, in this embodiment, as shown in FIG. Figure 6 and Figure 7As shown, the inner wall of the turntable 6 forms a concave first mounting groove 62, and the first mounting groove 62 is connected to the first through hole 61. The opening of the first mounting groove 62 and the first through hole 61 is smaller than the first mounting portion 721. As a preferred embodiment, the first mounting groove 62 can be set as a long arc-shaped groove body. The first mounting portion 721 is inserted into the first mounting groove 62 so that the second bearing 722 abuts against the inner wall of the first mounting groove 62. At this time, the first mounting portion 721 is basically placed in the first mounting groove 62 as a whole, so that when the turntable 6 rotates, the first mounting portion 721 will also rotate with the rotation direction of the turntable 6, as shown in FIG. Figure 5 As shown, the button needle mounting hole 723 for mounting the button needle 71 is formed on the button needle seat 72, and the inner wall of the button needle mounting hole 723 is provided with vertical surfaces 7231 arranged opposite to each other. The other end of the button needle 71 away from the twist foot groove 711 forms a second mounting portion 712, and the size and shape of the second mounting portion 712 are matched with the button needle mounting hole 723. A supporting portion 7232 for supporting the second mounting portion 712 is also provided in the button needle mounting hole 723. The two side edges of the second mounting portion 712 are also straight and match the position and size of the vertical surface 7231. The second mounting portion 712 is inserted into the button needle mounting hole 723, and the button needle seat 72 is suspended in the first through hole 61, so that the button needle 71 can pass through the first through hole 61 and the second through hole 531, the supporting part 7232 supports the button pin 71 to prevent it from falling. During assembly, the twist foot upper seat 52 will press the upper end of the button pin 71, so that the button pin 71 will not move upward due to the action of the rotor 1, so that the button pin 71 can only rotate with the first mounting part 721 and cannot move up and down. It should be particularly noted that the angle of the twist foot groove 711 matches the size, angle and direction of the T-shaped fixed foot 14, and the adjustment of the angle of the twist foot groove 711 can be flexibly adjusted by the setting angle of the vertical surface 7231 of the button pin mounting hole 723, that is, only the button pin seat 72 needs to be replaced to adjust the angle of the twist foot groove 711, and multiple groups of button pin seats 72 with vertical surfaces 7231 of different angles can be configured, and they can be selected and replaced according to needs;

[0038] like Figure 5 As shown, the turntable 6 is placed on the upper end of the twist foot lower seat 53, and the inner diameter of the second through hole 531 is smaller than the inner diameter of the first through hole 61, so that the turntable 6 and the twist foot lower seat 53 form a stepped distribution, and a plurality of groups of third through holes 532 matching the button needle 71 are provided on the twist foot lower seat 53, and the second mounting portion 712 is hooked on the periphery of the third through hole 532, and the other end of the button needle 71 passes through the third through hole 532, so that the twist foot groove 711 is placed below the twist foot lower seat 53.

[0039] The transmission assembly 8 is arranged on the fixed seat 4, and the transmission assembly 8 is connected with the turntable 6 to drive the turntable 6 to rotate along a fixed direction. Specifically, Figure 8 As shown, the transmission assembly 8 includes a first slide rail 81 and a twist foot cylinder 82 fixedly connected to the fixed base 4, the first slide rail 81 is movably connected with a first slider 83 connected to the twist foot cylinder 82, the first slider 83 is connected with a twist foot linkage block 84, the twist foot linkage block 84 is connected to the turntable 6, and a first limit block 85 is provided at the end of the first slider 83. The connection method between the above-mentioned twist foot linkage block 84 and the turntable 6 is specifically as follows: the side wings of the turntable 6 extend outward to form a linkage arm 63, and a third bearing 64 is arranged at the end of the linkage arm 63. The lower end of the twist foot linkage block 84 is provided with a third mounting groove 841, and the third bearing 64 is arranged at the upper end of the linkage arm 63. The third bearing 64 is clamped in the third mounting groove 841, and the linkage arm 63 is connected to the twist foot linkage block 84 through the third bearing 64. In order to prevent the third bearing 64 from sliding out of the third mounting groove 841 when the angle of rotation of the turntable 6 is limited to the limit, the depth of the third mounting groove 841 needs to be additionally increased. It is best if the depth of the third mounting groove 841 is consistent with the displacement size of the twist foot linkage block 84. Of course, it can also be slightly larger than the displacement size, as long as the third bearing 64 is guaranteed not to slide out.

[0040] In order to better position the rotor 1, the twist foot lower seat 53 is also fixed to the auxiliary positioning member 533, such as Figure 8 As shown, the auxiliary positioning member 533 is provided with a fourth through hole 5331 that matches the position of the first through hole 61 and the second through hole 531, and the auxiliary positioning member 533 is provided with a fifth through hole 5332 for passing the button needle 71, and the lower end of the auxiliary positioning member 533 extends downward to form a positioning portion 5333 arranged at intervals.

[0041] The working principle of the utility model is briefly described as follows: when the rotor 1 has been sent to the bottom of the utility model, the upper and lower cylinders 32 push the fixed seat 4 to move downward. When the fixed seat 4 reaches the second limit block 34, the upper and lower cylinders 32 stop working. At this time, the positioning column 51 can just abut against the top of the lower rotor 1, and the positioning column 51 axially positions the rotor 1 so that it cannot jump up and down. Furthermore, the auxiliary positioning member 533 will wrap the rotor 1, and its positioning portion 5333 will clamp the side edge of the rotor 1 so that it cannot rotate. At the same time, the twist foot groove 711 set by the button needle 71 is just inserted into the T-shaped fixed foot 14 of the rotor 1. Then the twist foot cylinder 82 is started to push the twist foot linkage block 84 to move. The third bearing 64 will slide under the action of the inner wall of the third mounting groove 841 and then drive the linkage arm 63 to deflect, thereby realizing the rotation of the turntable 6 body. When the turntable 6 body rotates, the same principle causes the first mounting portion 721 to rotate, thereby driving the button needle 71 to rotate, and realizing the torsional locking of the T-shaped fixed foot 14.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit 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.
