[0015] 1. A stirring rod is provided in the device. The motor output shaft drives the main shaft and the full gear to rotate. The full gear meshes to drive the half gear to rotate. The half gear drives the secondary shaft to reciprocate in the horizontal direction through the elliptical groove. When the secondary shaft moves laterally, the secondary shaft rotates around its own axis under the action of the driving assembly. Since the full gear and the half gear are periodically meshed together, when the two are disengaged, the rotation speed of the half gear will gradually decrease, which makes the stirring rod swing back and forth within a certain angle due to the centrifugal forces of different sizes. This makes the stirring rod not always rotate in the same plane, thereby improving the stirring efficiency of gypsum.

[0016] 2. The device is provided with a driving assembly. Under the push of the elliptical groove, the secondary shaft can move back and forth along the guide groove together with the guide block. When the secondary shaft moves laterally, the transmission gear and the rack form a meshing transmission, so that the secondary shaft rotates.

[0017] 3. The device is provided with a support plate. After the stirring is completed, the screw is rotated so that the slider drives the support plate and the cover plate to move upward. The support plate lifts the gypsum upward so that the liquid level of the gypsum can be closer to the top surface of the box, which makes it convenient for the staff to take the gypsum out of the box.

[0018] 4. The device is provided with a handle, which is turned to drive the screw to rotate through the transmission cooperation of the pulley and the belt. In addition, this arrangement can make the position of the handwheel on the handle closer to the ground, so that the staff can rotate the screw by standing on the ground and turning the handwheel.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5 A clinical plaster making device for orthopedic surgery includes a box body 1, a cover plate 2 is arranged on the box body 1, a motor 3 is fixed on the top of the cover plate 2, a main shaft 4 is connected to the output shaft of the motor 3, a full gear 5 located below the cover plate 2 is fixedly sleeved on the main shaft 4, a pair of half gears 6 are rotatably connected to the bottom of the cover plate 2, the half gear 6 is meshed with the full gear 5, an elliptical groove 7 is provided at the bottom of the half gear 6, a guide plate 9 is fixed to the bottom of the box body 1, a secondary shaft 8 that can move along the length direction of the guide plate 9 is arranged on the guide plate 9, the top of the secondary shaft 8 is located in the elliptical groove 7, two sets of sleeve frames 12 are fixed to the circumferential outer wall of the secondary shaft 8, a stirring rod 13 is rotatably connected to the sleeve frame 12, During stirring, the motor 3 is started, and the output shaft of the motor 3 drives the main shaft 4 and the full gear 5 to rotate, and the full gear 5 engages to drive the half gear 6 to rotate, and the half gear 6 drives the secondary shaft 8 to reciprocate in the lateral direction through the elliptical groove 7. When the secondary shaft 8 moves laterally, the secondary shaft 8 rotates around its own axis under the action of the driving assembly. Since the full gear 5 and the half gear 6 are periodically meshed together, when the two are disengaged, the rotation speed of the half gear 6 will gradually decrease, which makes the stirring rod 13 swing back and forth within a certain angle due to the centrifugal forces of different sizes, which makes the stirring rod 13 not always rotate in the same plane, thereby improving the stirring efficiency of the gypsum.

[0027] Furthermore, a pair of guide grooves 10 are provided on the guide plate 9, and a guide block 11 is slidably connected in the guide groove 10. The guide block 11 is sleeved on the secondary shaft 8 and forms a rotational connection therewith, so that under the push of the elliptical groove 7, the secondary shaft 8 can reciprocate along the guide groove 10 together with the guide block 11.

[0028] Furthermore, the driving assembly includes a pair of racks 15 fixed at the bottom of the guide plate 9, and a transmission gear 14 is fixedly sleeved on the secondary shaft 8. The transmission gear 14 is meshingly connected with the rack 15. When the secondary shaft 8 moves laterally, the transmission gear 14 and the rack 15 form a meshing transmission, so that the secondary shaft 8 rotates.

[0029] Furthermore, the bottom end of the main shaft 4 passes through the guide plate 9, and a spiral stirring blade 16 is fixed on the main shaft 4. When the main shaft 4 rotates, the spiral stirring blade 16 is driven to rotate, so that the gypsum can be rolled upward during stirring, thereby preventing the gypsum from being deposited under the box 1.

[0030] Furthermore, handles 17 are fixed on both sides of the box 1, and a plurality of self-locking universal wheels 18 distributed at the corners are installed at the bottom of the box 1, so that the device can be pushed by the handles 17 to move on the ground through the self-locking universal wheels 18, which facilitates the transfer of the device.

[0031] Furthermore, an adjusting frame 19 is fixed at the rear of the box body 1, and a slide groove 20 is opened on the adjusting frame 19. A slider 21 is slidably connected in the slide groove 20, and an L-shaped support plate 23 that can be inserted into the box body 1 is fixed at the front end of the slider 21. The cover plate 2 is fixedly connected to the support plate 23, and a screw rod 22 is rotatably connected in the slide groove 20. The screw 22 is threadedly connected to the slider 21. After stirring is completed, the screw 22 is rotated to make the slider 21 drive the support plate 23 and the cover plate 2 to move upward, and the support plate 23 lifts the gypsum upward, so that the liquid level of the gypsum can be closer to the top surface of the box body 1, which makes it convenient for the staff to take the gypsum out of the box body 1.

[0032] Furthermore, an ear block 24 is fixed to one side of the adjustment frame 19, and a handle 25 is rotatably connected to the ear block 24. The handle 25 and the top of the screw rod 22 are fixedly sleeved with a pulley 26, and the two pulleys 26 are connected by a belt 27. The handle 25 is rotated, and the screw rod 22 is driven to rotate through the transmission cooperation of the pulley 26 and the belt 27. In addition, this arrangement can make the position of the handwheel on the handle 25 closer to the ground, so that the staff can rotate the screw rod 22 by standing on the ground and turning the handwheel.
