In this embodiment, the support assembly 100 includes a bracket 101, the bracket 101 is arranged on the workbench or installed on the ground by using the lower rods. A bracket table 102 is further arranged on the bracket 101, a bracket body 103 is arranged on the bracket table 102, and an up-and-down sliding member 104 is further arranged on the bracket body 103. The up-and-down sliding member 104 can slide up and down and synchronously drive the longitudinal movement of the bracket body 103.

[0029] Further, the present invention further includes an engraving and milling assembly 200. In this embodiment, the engraving and milling assembly 200 includes an engraving and milling component 201 arranged on the bracket table 102, an auxiliary locking component 202 arranged on the bracket table 102, a steering component 500 arranged on the auxiliary locking component 202, and a cooling component arranged on the engraving and milling component 201. The cooling component is used to cool the engraving and milling component 201; In this embodiment, the engraving and milling component 201 includes an engraving and milling block body 201a connected to the bracket body 103 and an engraving and milling cutter 201b arranged on the engraving and milling block body 201a.

[0030] Preferably, the bracket body 103 is arranged on the middle side wall of the bracket platform 102, and the up and down sliding member 104 includes a screw 104a arranged on the bracket platform 102, a slider 104b arranged on the bracket body 103, and a first motor 104c arranged at the lower end of the screw 104a. The screw 104a is vertically arranged and driven by the first motor 104c. The rotation of the screw can drive the slider 104b to slide in the longitudinal direction. In order to limit the movement of the slider 104b, a guide rod is arranged on the bracket 101. The guide rod passes through the slider 104b and limits and guides the slider 104b.

[0031] Furthermore, the present invention also includes an auxiliary locking component 202. In this embodiment, the auxiliary locking component 202 includes a main plate 202a arranged on the bracket platform 102, a support frame 202b arranged on the main plate 202a, an ejection frame 202c slidably connected to the support frame 202b, and a plurality of auxiliary plug-ins 202d arranged on the ejection frame 202c, a rotating member 400 is arranged on the support frame 202b, and a scale standard is arranged on the rotating member 400.

[0032] The main body plate 202a is fixedly connected to the support frame 202b, and the push-out frame 202c is arranged on both sides of the support frame 202b. The push-out frame 202c is entirely arranged parallel to the support frame 202b.

[0033] Furthermore, in this embodiment, the rotating member 400 includes a rotating rod 401 rotatably connected to the support frame 202b, a central rotating plate 402 arranged on the rotation, an output rod 403 hinged at both ends of the central rotating plate 402, and a hinged sleeve 404 arranged at the end of the output rod 403, the hinged sleeve 404 is rotatably connected to the ejection frame 202c, and a damping member is arranged on the rotating rod 401.

[0034] Furthermore, a temporary storage groove 405 is provided on the ejection frame 202c, and a smear plate 406 is detachably connected in the temporary storage groove 405, and the smear plate 406 is connected to the auxiliary plug-in 202d.

[0035] Furthermore, in this embodiment, the auxiliary plug-in 202d includes a connecting rod connected to the smear plate 406 and a plurality of connecting protrusions arranged on the connecting rod.

[0036] Furthermore, in this embodiment, the spherical supporting member includes a frame 501 arranged at the central position of the main body plate 202a, a lifting member 502 arranged on the frame 501, a plurality of first rotating grooves 503 opened on the lifting member 502, a second rotating groove 504 opened between every two adjacent first rotating grooves 503, a control panel 505 arranged on the frame 501, and a toggle lever 506 arranged on the control panel 505.

[0037] When observed from the front, the first rotating groove 503 is semicircular in shape. In the present embodiment, four first rotating grooves 503 are provided, and the spacing between each first rotating groove 503 is consistent. In the present embodiment, the outer wall of the supporting member 502 is in contact with the inner wall of the frame 501, and the upper end surfaces of the supporting member 502 and the frame 501 are parallel, while the second rotating groove 504 is vertical in shape and is provided along the spherical shape of the supporting member 502. At the same time, the toggle rod 506 rotates with the control panel 505, and enters the second rotating groove 504 after rotation, and after the toggle rod 506 rotates, it will toggle the rotation of the supporting member 502.

[0038] Furthermore, the lifting member 502 is rotatably connected to the frame 501, an arc-shaped extension plate 507 is provided on the control panel 505, an extension plate 507 extends outward from the control panel 505, and the extension plate 507 is arranged in an arc shape, and the toggle rod 506 is arranged at the end of the extension plate 507, a grabbing member is arranged in the middle position of the control panel 505, and a sliding member 600 is arranged at the rear end of the control panel 505.

[0039] Furthermore, an arc-shaped guide bar 508 is provided on the control disk. When the control disk 505 rotates, the extension plate 507 is connected to the control disk 505, and the shape of the second rotation groove 205d is longitudinal, so the rotation of the control disk 505 drives the rotation of the extension plate 507. During this rotation process, the control disk 505 will not be engaged with the first rotation groove 503. The length of this arc-shaped guide bar 508 is half of the arc of the control disk 505, and it is directly opposite to the extension plate 209. When the toggle rod 506 is turned, the control disk 505 will not be engaged with the first rotation groove 503. When driving the entire supporting member 502 to rotate, the arc guide bar 508 is rotated out of the first rotating groove 503, and then as the toggle rod 506 continues to drive the supporting member 502 to rotate and moves to the position of the next first rotating groove 503, the arc guide bar 508 is again inserted into the first rotating groove 503. At this time, the toggle rod 506 is disengaged from the previous second rotating groove 504, thereby completing a rotation of the supporting member 502. At this time, a 90° rotation of the supporting member 502 in the horizontal direction can be completed.

[0040] A plurality of sieving holes are provided on the surface of the unloading sieve plate 104d, and an auxiliary sieve plate 204 is slidably connected to the lower end of the unloading sieve plate 104d. The auxiliary sieve plate 204 is provided with auxiliary sieve holes 205 corresponding to the sieving holes, and the size ratio of the auxiliary sieve holes 205 to the sieving holes is 1:1.2-1:1.3, so that the unloading sieve plate 104d can be used to sieve pills of different diameters. At the same time, because the auxiliary sieve plate 204 is provided with auxiliary sieve holes 205, the sieve holes on the unloading sieve plate 104d are larger than the auxiliary sieve holes 205.

[0041] An adjustment member 300 is provided on the secondary sieve holes 205. In this embodiment, the adjustment member 300 includes a first ring member 301 provided on the secondary sieve holes 205, a second ring member 302 provided on the sieve movement holes, and a linkage member provided between the first ring member 301 and the second ring member 302. In this embodiment, the linkage member includes a plurality of sets of annularly arranged linkage rod groups. In this embodiment, the number of linkage rod groups is set to 3, and the linkage rod groups are arranged equidistantly along the ring. Each linkage rod group includes a first connecting rod 303 rotatably connected to the inner wall of the second ring member 302 and a second connecting rod 304 rotatably connected to the inner wall of the first ring member 301, and the first connecting rod 303 and the second connecting rod 304 are hinged to each other. Thus, when the first ring member 301 slides downward, it will drive the swing of the second connecting rod 304, thereby realizing the approach or separation of the positions between the second connecting rod 304 and the first connecting rod 303. When the first ring member 301 moves downward, the second connecting rod 304 and the first connecting rod 303 are in a state of moving away from each other, and when the first ring member 301 is in the upper position, the first connecting rod 303 and the second connecting rod 304 are in a state of approaching each other.

[0042] Furthermore, a vibration member is provided inside the second ring member 302. In this embodiment, the vibration member includes a first clamping block provided on the first connecting rod 303 and a second clamping block provided on the second connecting rod 304. The first clamping block and the second clamping block are arranged oppositely. When the first connecting rod 303 and the second connecting rod 304 move away from each other, the first clamping block also moves away from the second clamping block. An elastic member 305 is also provided between the first clamping block and the second clamping block. The elastic member 305 includes a spring and connecting strips provided at both ends of the spring. Matching grooves for the connecting strips are formed on both the first clamping block and the second clamping block, so that the spring is detachable.

[0043] The remaining structure is the same as that of Embodiment 1.

[0044] Operation process: When installing parts, the operator manually rotates the rotating member 400 according to the installation requirements. The rotation of the rotating member 400 will drive the rotation of the central rotating plate 402. Since both ends of the central rotating plate 402 extend outward, it will drive the two output rods 403 to move outward, thereby driving the two pushing frames 202c to move away from each other, so as to clamp the parts in the central position, and control the connecting lifting member 502 as needed to rotate the parts.
