[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. During the movement, the material extraction port of the shelf shell is located inside the mounting shell, so the material extraction port of the shelf shell can be sealed to prevent fragile objects such as medicine bottles storing medicines from being shaken out when the medicine changing device encounters an obstacle and shakes during the movement, which is beneficial to the shielding and protection of the medicines. While the support tube rotates, the first linkage gear is driven to rotate by the transmission mechanism, and the first linkage gear synchronously drives the follower gear to rotate. The follower gear drives the shelf shell to rotate through the connecting shaft, and the shelf shell moves the material extraction port out, so that when in use, as the collecting trough is adjusted to the collecting position, the material extraction port of the shelf shell is synchronously moved out, thereby making it convenient for nursing staff to take medicines without having to adjust the shelf shell separately, which is convenient and quick.

[0024] Second, the support tube is driven to rotate ninety degrees by a rotary drive mechanism. When the support tube rotates, the collection tank is driven to rotate ninety degrees synchronously. Then, the collection tank is kept consistent with the extension direction of the platform, so that the top of the platform can be received, so that the dripping liquid and garbage during the cleaning process can directly fall into the collection tank arranged in the front and rear directions, so that the collection tank can maintain a large receiving area, and when not in use, it is kept arranged in the extension direction of the mobile seat, avoiding the collection tank from occupying too much horizontal space when moving in order to increase the receiving area, thereby facilitating the movement and use of nursing staff.

[0025] 3. When the material taking port moves out of the mounting shell and reaches the ideal position, the limit block will contact the right side of the opening edge of the front side of the mounting shell to form a limit. Under the elastic support of the first arc-shaped support spring, the collision force can be buffered to avoid damage to the limit block caused by excessive collision force. The limit is achieved, and then the material taking port is restricted to the opening on the front side of the mounting shell, which makes it convenient for nursing staff to directly take out medicine bottles, etc. through the material taking port, thereby ensuring the normal use of the scald dressing change device.

[0026] Fourth, when the threaded rod is not adjusted and rotated, the U-shaped limiter will limit the linkage ring to prevent the threaded rod from being misoperated during the movement or restriction process, so that the shelf shell and the collecting tank remain in a stable restricted state, avoiding misoperation and affecting the safety of movement; when the linkage ring is above the trapezoidal block, under the elastic reset action of the first gas spring, the second linkage plate and the trapezoidal block are driven to reset and limit the bottom of the linkage ring, to prevent the support tube from being reset and rotated due to unwarranted operation by medical staff after the support tube rotates ninety degrees, thereby ensuring that the use state of the collecting tank and the shelf shell remains stable, which is conducive to the stable use of the burn dressing change device and the normal operation of the dressing change work.

[0041] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0042] like Figures 2 to 13 The burn dressing changing device shown in the figure is applied clinically, comprising a movable base 1, universal wheels 2 being fixedly mounted at the four corners of the bottom of the movable base 1, a support column 3 being fixedly connected to the top of the movable base 1, a platform 4 being fixedly connected to the top of the support column 3, a support tube 5 being rotatably connected to the surface of the support column 3, a collection tank 6 being fixedly connected to the upper end of the surface of the support tube 5, a mounting shell 7 having an opening on the front being further fixedly connected to the top of the movable base 1, a shelf shell 8 being provided inside the mounting shell 7, a connecting shaft 9 being fixedly connected to the top of the shelf shell 8, and the connecting shaft 9 being rotatably connected to the inner wall of the mounting shell 7;

[0043] The top end of the connecting shaft 9 passes through the mounting shell 7 and is fixedly connected to a follower gear 10. The back of the follower gear 10 is engaged with a first linkage gear 11. The first linkage gear 11 is rotatably connected to the top of the mounting shell 7. The back of the shelf shell 8 is provided with a material taking port 12, and the inner wall of the shelf shell 8 is provided with a shelf plate 13.

[0044] A transmission mechanism is connected between the first linkage gear 11 and the support tube 5. The top of the movable base 1 is also connected to a rotation drive mechanism, which is used to drive the support tube 5 to rotate ninety degrees.

[0045] During operation, in the prior art, most nursing staff use the dressing changing device to carry out dressing change for burn patients. Since it is inconvenient for burn patients to move to the nursing room, the dressing changing device needs to be moved to the front of the burn patients for nursing. The dressing changing device has a collection tank 6 for storing garbage and waste liquid, and a storage device for storing nursing medicines. During the movement, if the storage device cannot be sealed and covered in time, when encountering obstacles, fragile objects such as medicine bottles used for nursing are easy to fall out and cause damage. In addition, the collection tank 6 for collecting waste liquid and storing garbage is used to reduce the space occupied. , is relatively small, and during the cleaning process, it is easy to cause waste liquid to spill, affecting the nursing environment; this embodiment of the present invention can solve the above problem, and the specific working method is as follows: the side of the mobile seat 1 can be fixedly installed with a pushing frame 101, and the material taking port 12 of the shelf shell 8 is located inside the mounting shell 7 during the movement, so the material taking port 12 of the shelf shell 8 can be sealed to prevent fragile objects such as medicine bottles storing medicines from being shaken out when the dressing device encounters an obstacle and shakes during the movement, which is beneficial to the shielding and protection of the medicines. Then, when it is moved to the bed of the burn patient, the support tube 5 is driven by the rotary drive mechanism to rotate ninety degrees. When the support tube 5 rotates, the collection tank 6 is driven to rotate ninety degrees synchronously, and then the collection tank 6 is kept consistent with the extension direction of the platform 4, so that the top of the platform 4 can be received, so that the dripping liquid and garbage during the cleaning process can directly fall into the collection tank 6 arranged in the front and rear directions, so that the collection tank 6 can maintain a large receiving area, and when not in use, it is kept arranged in the extension direction of the mobile seat 1 to avoid the collection tank 6 from increasing the receiving area. The lateral space occupied during movement is too large, which facilitates the movement and use of nursing staff. While the support tube 5 rotates, the first linkage gear 11 is driven to rotate through the transmission mechanism, and the first linkage gear 11 synchronously drives the follower gear 10 to rotate. The follower gear 10 drives the shelf shell 8 to rotate through the connecting shaft 9, and the shelf shell 8 moves the material taking port 12 out, so that when in use, as the collecting trough 6 is adjusted to the collection position, the material taking port 12 of the shelf shell 8 is synchronously moved out, thereby facilitating the nursing staff to take medicine without having to adjust the shelf shell 8 separately, which is convenient and quick.

[0046] As an embodiment of the present invention, the rotation driving mechanism includes a threaded rod 14 and a spiral groove 17. The threaded rod 14 is rotatably connected to the top of the moving seat 1. The top of the threaded rod 14 is fixedly connected to a rotating handle. A linkage ring 15 is threadedly connected to the surface of the threaded rod 14. The linkage ring 15 is slidably sleeved on the surface of the support tube 5. A linkage pin 16 is fixedly connected to the inner wall of the linkage ring 15. The spiral groove 17 is opened on the surface of the support tube 5, and the linkage pin 16 is slidably connected to the inner wall of the spiral groove 17; during operation, when it is necessary to drive the support tube 5 to rotate, the threaded rod 14 is manually rotated by the rotating disk 41. The threaded rod 14 will drive the linkage ring 15 threaded on the surface to move upward, and the linkage ring 15 drives the linkage pin 16 to move inside the spiral groove 17. The linkage pin 16 acts on the spiral groove 17 to cause the support tube 5 to rotate. Under the restriction of the spiral groove 17, when the support tube 5 rotates ninety degrees, the linkage pin 16 moves to the top of the spiral groove 17 and cannot continue to rise, and the rotation is completed.

[0047] As an embodiment of the present invention, the transmission mechanism includes a transmission disc 18, a first transmission groove 19, and a group of guide wheels 20. The transmission disc 18 is fixedly connected to the surface of the support tube 5. The first transmission groove 19 is opened on the surface of the first linkage gear 11. An arc-shaped connecting groove 21 is opened on the inner wall of the first transmission groove 19. A moving slider 22 is slidably connected to the inner wall of the arc-shaped connecting groove 21. An elastic support member is connected between the side surface of the moving slider 22 and the inner wall of the arc-shaped connecting groove 21. A first linkage rope 23 is fixedly connected to the surface of the moving slider 22. One end of the first linkage rope 23 away from the moving slider 22 is moved along the first transmission groove 1 9 is fixedly connected to the transmission wall of the transmission disc 18 after passing through the groove wall trajectory, and the mobile slider 22 is fixedly connected to the transmission wall of the transmission disc 18 at one end thereof, and the second linkage rope 24 is fixedly connected to the groove wall of the first transmission groove 19 after passing through the transmission wall of the transmission disc 18. A set of guide wheels 20 is two in number, and the two guide wheels 20 are set in relative contact. The two guide wheels 20 are rotatably connected to the top of the mounting shell 7. The two guide wheels 20 are located between the first linkage gear 11 and the support tube 5. The second linkage rope 24 passes between the two guide wheels 20. A first limiting mechanism is connected to the surface of the shelving shell 8. The first limiting mechanism It is used to limit the range of rotation of the shelf shell 8 relative to the mounting shell 7; during operation, when the support tube 5 rotates ninety degrees, the transmission disc 18 will synchronously drive the first linkage rope 23 to reel in, and the first linkage rope 23 will pull the movable slider 22 to move, and the movable slider 22 will drive the first linkage gear 11 to rotate under the support of the elastic support member, and the first linkage gear 11 drives the follower gear 10 to rotate, and the follower gear 10 synchronously drives the shelf shell 8 to rotate through the connecting shaft 9, thereby moving the material taking port 12 out. In the process of continuing to rotate, the limiting mechanism will limit the rotation of the shelf shell 8. At this time, the first linkage rope 23 It will drive the moving slider 22 to compress the elastic support part, avoiding mutual restriction between the first linkage gear 11 and the transmission disk 18, so that the shelf shell 8 can be rotated to an ideal state, realizing mutual linkage, and when the support tube 5 is rotated and reset, the support tube 5 will drive the transmission disk 18 to rotate and reset, and the transmission disk 18 will drive the second linkage rope 24 to pull the first linkage gear 11 to rotate and reset, and the first linkage gear 11 drives the follower gear 10, the connecting shaft 9 and the shelf shell 8 to rotate and reset as a whole, and the shielding is realized again, without the need for separate adjustment by the nursing staff, and the shelf shell 8 can be reset in linkage at the same time as the storage slot is reset, which is convenient and quick.

[0048] As an embodiment of the present invention, the first limiting mechanism includes an arc-shaped limiting groove 25, which is opened on the surface of the shelf shell 8, and a limiting block 26 is slidably connected to the inner wall of the arc-shaped limiting groove 25, and the end of the limiting block 26 extends to the outside of the arc-shaped limiting groove 25, and the rear side of the limiting block 26 contacts the front side of the shelf shell 8. A first arc-shaped supporting spring 27 is provided inside the arc-shaped limiting groove 25, and the two ends of the first arc-shaped supporting spring 27 are respectively fixedly connected to the inner wall of the arc-shaped limiting groove 25 and the surface of the limiting block 26; during operation, as the transmission disk 18 rotates ninety degrees, the first linkage rope 23 pulls the first linkage gear 11 to rotate synchronously. If there is no elastic give way, the angle of rotation of the follower gear 10 driven by the first linkage gear 11 cannot be accurately controlled. The system may easily cause the shelf shell 8 to rotate too much, causing the material taking port 12 to re-enter the mounting shell 7. This embodiment of the present invention can solve the above problem. The specific working method is as follows. In the process of the follower gear 10 driving the shelf shell 8 to rotate through the connecting shaft 9, when the material taking port 12 moves out of the mounting shell 7 and reaches the ideal position, the limit block 26 will contact the right side of the opening edge of the front of the mounting shell 7 to form a limit, and under the elastic support of the first arc-shaped support spring 27, the collision force can be buffered to avoid damage to the limit block 26 caused by excessive collision force, and the limit is achieved. Then, the material taking port 12 is restricted to the opening at the front of the mounting shell 7, which makes it convenient for nursing staff to directly take out medicine bottles, etc. through the material taking port 12, thereby ensuring the normal use of the scald dressing device.

[0049] As an embodiment of the present invention, the elastic support member includes an arc-shaped connecting rod 28, which is fixedly connected to the inner wall of the arc-shaped connecting groove 21. The arc-shaped connecting rod 28 is inserted through the movable slider 22, and a second arc-shaped support spring 29 is sleeved on the surface of the arc-shaped connecting rod 28. The two ends of the second arc-shaped support spring 29 are respectively fixedly connected to the movable slider 22 and the inner wall of the arc-shaped connecting groove 21; when working, by providing the arc-shaped connecting rod 28 and the second arc-shaped support spring 29, elastic support for the movable slider 22 is played, so that when the shelf shell 8 is limited, the first linkage rope 23 pulls the movable slider 22 to compress the second arc-shaped support spring 29, on the one hand, so that the first linkage gear 11 will not be driven to rotate by the first linkage rope 23, and on the other hand, it avoids restricting the rotation of the transmission disk 18, thereby achieving the situation that when the material taking port 12 of the linkage shelf shell 8 moves to the opening at the front of the mounting shell 7, the rotation of the support tube 5 will not be hindered, thereby ensuring the normal adjustment and use of the entire scald dressing device.

[0050] As an embodiment of the present invention, the top of the movable seat 1 is also connected to a second limiting mechanism, and the second limiting mechanism includes a first sliding groove 30 and a second sliding groove 31. The first sliding groove 30 and the second sliding groove 31 are opened at the top of the movable seat 1, and the first sliding groove 30 and the second sliding groove 31 are located on both sides of the support tube 5. The inner walls of the first sliding groove 30 and the second sliding groove 31 are respectively slidably connected with the first movable plate 32 and the second movable plate 33. The top of the first movable plate 32 is fixedly connected with a U-shaped limiting member 34. The top of the U-shaped limiting member 34 is provided with a first guiding inclined surface. The U-shaped limiting member 34 is clamped on the top of the second movable plate 33 and is fixedly connected with a trapezoidal block 35. On the outer surface of the linkage ring 15, the trapezoidal block 35 is located on the linkage ring 15 The first movable plate 32 is fixedly connected to the upper side of the second movable plate 33 on the opposite sides of the first movable plate 32 and the second movable plate 33. A first gas spring 37 is fixedly connected between the ends of the two curved connecting plates 36. A first return spring 38 is fixedly connected between the side surface of the first movable plate 32 and the inner wall of the first sliding groove 30. A traction device is also connected to the side surface of the first movable plate 32 to move the first movable plate 32 to the left. During operation, since the threaded rod 14 cannot be restricted after the rotation adjustment is completed, the nursing staff may mistakenly operate the threaded rod 14 to rotate, affecting the storage state of the storage groove. This embodiment of the present invention can solve the above-mentioned problem. The specific working method is as follows: when the threaded rod 14 is not adjusted and rotated, the U-shaped limit The positioning member 34 will limit the linkage ring 15 to prevent the threaded rod 14 from being misoperated during the movement or restriction process, so that the shelf shell 8 and the collection tank 6 remain stably in the restricted state to avoid misoperation and affect the safety of movement. When it reaches the burn patient for use, the first movable plate 32 is pulled to the left by the traction device, so that the first movable plate 32 drives the U-shaped limiting member 34 to move to the left, thereby canceling the restriction on the linkage ring 15, so that the medical staff can rotate the threaded rod 14 and move the linkage ring 15 upward. In the process of the first movable plate 32 driving the U-shaped limiting member 34 to disengage from the linkage ring 15, the first movable plate 32 drives the second movable plate under the elastic support of the arc connecting plate 36 and the first gas spring 37. When the second movable plate 33 is moved to the left, the trapezoidal block 35 on the top of the second movable plate 33 is located directly above the linkage ring 15. In the process of the linkage ring 15 moving past the trapezoidal block 35, the linkage ring 15 will squeeze the inclined surface of the trapezoidal block 35 so that the trapezoidal block 35 drives the second movable plate 33 to make way. Then, when the linkage ring 15 is located above the trapezoidal block 35, under the elastic reset action of the first gas spring 37, the second linkage plate and the trapezoidal block 35 are driven to reset and limit the bottom of the linkage ring 15, so as to avoid the support tube 5 being reset and rotated due to the medical staff's unreasonable operation after the support tube 5 rotates ninety degrees, thereby ensuring that the use status of the collection tank 6 and the shelf shell 8 remains stable, which is conducive to the stable use of the burn dressing change device and the normal operation of the dressing change work.

[0051] As an embodiment of the present invention, the traction device includes a traction frame 39, which is fixedly connected to the side of the first movable plate 32, and a traction pin 40 is slidably provided on the inner wall of the traction frame 39. The bottom end of the traction pin 40 is fixedly connected to the rotating disk 41 after passing through the traction frame 39, and the bottom center position of the rotating disk 41 is fixedly connected to a support screw 42, and the support screw 42 is rotatably connected to the top of the movable seat 1. The surface of the support screw 42 is threadedly connected to a connecting sleeve 43 with an internal thread, and the surface of the connecting sleeve 43 is fixedly connected to a pedal 44, and a second return spring 45 is fixedly connected between the bottom of the pedal 44 and the movable seat 1. The top of the pedal 44 is located at the positions of the first movable plate 32, the second movable plate 33, the mounting shell 7, the threaded rod 14, and the support tube 5, and a clearance opening is provided. The side of the rotating disk 41 is connected to a ratchet one-way limit mechanism, and the ratchet one-way limit mechanism stops rotating when the rotating disk 41 When the first movable plate 32 needs to move to the left, the first movable plate 32 is pressed downward to squeeze the pedal 44, so that the pedal 44 moves downward, the pedal 44 drives the connecting sleeve 43 to move downward, the internal thread of the connecting sleeve 43 drives the support screw 42 to rotate, the support screw 42 drives the rotating disk 41 to rotate, the rotating disk 41 drives the traction pin 40 to move, and the traction pin 40 pulls the traction frame 39 to the left until the first movable plate 32 drives the U-shaped limit piece 34 to cancel the limit of the linkage ring 15, and at the same time the first movable plate 32 compresses the first return spring 38. When the U-shaped limit piece 34 is disengaged from the limit of the linkage ring 15, the stepping on the pedal 44 is canceled. At this time, the ratchet one-way limit mechanism limits the rotation position of the rotating disk 41 in one direction, preventing the pedal 44 from being reset by the support screw 42 when the second return spring 45 is supported.

[0052] As an embodiment of the present invention, the ratchet one-way limiting mechanism includes an arc-shaped mounting plate 46 and an annular tooth 47. The end of the arc-shaped mounting plate 46 is fixedly connected to a support rod 48. The bottom end of the support rod 48 passes through the pedal 44 and is rotatably connected to the top of the movable plate. A torsion spring 49 is sleeved on the surface of the support rod 48. The two ends of the torsion spring 49 are respectively fixedly connected to the surface of the support rod 48 and the top of the movable seat 1. Three support prisms 50 distributed in an annular array are slidably inserted on the inner arc surface of the arc-shaped mounting plate 46. The end of the support prism 50 is fixedly connected to a snap-in pin 51, the annular gear 47 is fixedly connected to the surface of the rotating disk 41, the tooth end of the annular gear 47 is provided with a second guiding arc surface, the engaging pin 51 is inserted in the gap between the adjacent teeth, and the surface of the supporting prism 50 is fixedly connected to the third return spring 52, the two ends of the third return spring 52 are respectively fixedly connected to the inner arc surface of the arc-shaped mounting plate 46 and the engaging pin 51, and the end of the arc-shaped mounting plate 46 is fixedly connected to the toggle plate 53; during operation, if the state after the rotating disk 41 rotates and is pulled cannot be limited, stepping on the pedal 44 will cause the second return spring 45 to stop. The support is reset, and then the rotating disk 41 is driven to rotate and reset by the supporting screw 42, thereby restoring the position of the first movable plate 32, and at the same time driving the second movable plate 33 to drive the trapezoidal block 35 to move to the original position, and the limiting effect cannot be started, which is not conducive to the stable use of the burn dressing device in the later stage. This embodiment of the present invention can solve the above-mentioned problem. The specific working method is as follows: during the rotation of the rotating disk 41, the second guiding inclined surface of the tooth end of the annular tooth 47 will squeeze the engaging pin 51, so that the engaging pin 51 squeezes the third reset spring 52, and the gear The teeth can break through the limit of the locking pin 51. After the rotation is completed, the locking pin 51 will be inserted into the gap between the teeth at the corresponding position. When the rotating disk 41 wants to rotate and reset, the locking pin 51 will limit the reverse movement of the teeth, thereby realizing one-way limit, avoiding the reverse rotation of the rotating disk 41, and maintaining the stability of the adjusted state. When the limit needs to be canceled, it is only necessary to swing the toggle plate 53 so that the toggle plate 53 drives the arc-shaped mounting plate 46 and the locking pin 51 to rotate. The arc-shaped mounting plate 46 will drive the locking pin 51 away from the gap between the teeth, thereby canceling the one-way limit and facilitating adjustment.

[0053] As an embodiment of the present invention, four second gas springs 54 are fixedly connected to the bottom of the pedal 44, and the bottom ends of the second gas springs 54 are fixedly connected to support legs 55. The bottom ends of the support legs 55 pass through the movable seat 1 and are fixedly connected to friction plates 56. During work and in the process of nursing, the burned leg or arm is often placed on the placing table 4 of the dressing changing device. If the dressing changing device is in use, the shaking of the burned person may easily cause the movement of the entire burn dressing changing device, which is not convenient for stable dressing changing. This embodiment of the present invention can solve the above-mentioned problem. When the pedal 44 is stepped on, the pedal 44 will move downward as a whole through the second gas springs 54 and the support legs 55. The support legs 55 will drive the friction plates 56 to rub against the ground, and when the pedal 44 continues to move downward, the second gas springs 54 will be compressed, thereby increasing the extrusion force, thereby strengthening the friction between the friction plates 56 and the ground, restricting the movement of the movable plate, and helping to maintain the stability of the entire burn dressing changing device.

[0054] like Figure 1 The operating method of a burn dressing changing device for clinical use is shown, and the operating method includes the following steps:

[0055] Step 1: Move the burn dressing device to the side of the burn patient;

[0056] Step 2: Adjust the use state: The support tube 5 is driven to rotate by the rotary drive device, and the support tube 5 drives the first linkage gear 11 through the transmission device. The first linkage gear 11 drives the driven gear 10 to rotate, thereby driving the shelf shell 8 to rotate, and the material extraction port 12 is moved to the opening of the mounting shell 7, so that the collecting trough 6 and the shelf shell 8 are both in the ready-to-use state;

[0057] Step 3: Reset and adjust after the dressing change is completed: the support tube 5 is driven to reset by the rotary drive device, and the collecting tank 6 and the shelf shell 8 are synchronously linked to reset.

[0058] Working principle:

[0059] During operation, in the prior art, most nursing staff use the dressing changing device to carry out dressing change for burn patients. Since it is inconvenient for burn patients to move to the nursing room, the dressing changing device needs to be moved to the front of the burn patients for nursing. The dressing changing device has a collection tank 6 for storing garbage and waste liquid, and a storage device for storing nursing medicines. During the movement, if the storage device cannot be sealed and covered in time, when encountering obstacles, fragile objects such as medicine bottles used for nursing are easy to fall out and cause damage. In addition, the collection tank 6 for collecting waste liquid and storing garbage is used to reduce the space occupied. , is relatively small, and during the cleaning process, it is easy to cause waste liquid to spill, affecting the nursing environment; this embodiment of the present invention can solve the above problem, and the specific working method is as follows: the side of the mobile seat 1 can be fixedly installed with a pushing frame 101, and the material taking port 12 of the shelf shell 8 is located inside the mounting shell 7 during the movement, so the material taking port 12 of the shelf shell 8 can be sealed to prevent fragile objects such as medicine bottles storing medicines from being shaken out when the dressing device encounters an obstacle and shakes during the movement, which is beneficial to the shielding and protection of the medicines. Then, when it is moved to the bed of the burn patient, the support tube 5 is driven by the rotary drive mechanism to rotate ninety degrees. When the support tube 5 rotates, the collection tank 6 is driven to rotate ninety degrees synchronously, and then the collection tank 6 is kept consistent with the extension direction of the platform 4, so that the top of the platform 4 can be received, so that the dripping liquid and garbage during the cleaning process can directly fall into the collection tank 6 arranged in the front and rear directions, so that the collection tank 6 can maintain a large receiving area, and when not in use, it is kept arranged in the extension direction of the mobile seat 1 to avoid the collection tank 6 from increasing the receiving area. The lateral space occupied during movement is too large, which facilitates the movement and use of nursing staff. While the support tube 5 rotates, the first linkage gear 11 is driven to rotate through the transmission mechanism, and the first linkage gear 11 synchronously drives the follower gear 10 to rotate. The follower gear 10 drives the shelf shell 8 to rotate through the connecting shaft 9, and the shelf shell 8 moves the material taking port 12 out, so that when in use, as the collecting trough 6 is adjusted to the collection position, the material taking port 12 of the shelf shell 8 is synchronously moved out, thereby facilitating the nursing staff to take medicine without having to adjust the shelf shell 8 separately, which is convenient and quick.
