[0002] In the maintenance, repair, and disinfection of medical equipment, the rapid and precise disassembly of components is a core element in ensuring the normal operation of the equipment and medical safety. Medical equipment has a precise structure, diverse component specifications, and extremely high requirements for the cleanliness of the operating environment and the precision of operation. Different types of bolts or screws are used to install and fix components. However, when disassembling different types of bolts or screws, traditional hand tools such as electric screwdrivers require frequent bit changes, making the disassembly of medical equipment components cumbersome and inefficient. Although some automated disassembly equipment exists on the market, these automated devices are bulky and difficult to use flexibly in space-constrained settings such as operating rooms and treatment rooms. Furthermore, their cleaning and disinfection processes are complex and can easily lead to the risk of cross-infection. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a quick disassembly device for parts. The technical solution adopted is as follows: a handle is included, one end of which is fixedly connected to the side of a U-shaped support base. A battery is fixedly installed inside the handle. A button electrically connected to the battery is fixedly installed on the side of the handle. The opposite side of the other end of the support base is fixedly connected to the opposite side of a fixed cylinder. A switching mechanism is installed on the fixed cylinder, and a driving mechanism is installed inside the fixed cylinder. The switching mechanism includes bearings, a rotating ring, bits, and connecting grooves. Two bearings are provided. The inner rings of the two bearings are fixedly connected to the sides of both ends of the fixed cylinder. The outer rings of the two bearings are fixedly connected to the inner side of the rotating ring. Several bits are rotatably installed on the side of the rotating ring. A hexagonal connecting groove is opened on the end face of the bit near the rotating ring. A through groove that mates with the connecting groove is opened on the side of the rotating ring.

[0004] The driving mechanism includes a connecting rod, a drive gear, a transmission gear, a motor, and a guide rod. The motor is fixedly mounted on a protruding part on the inner side of the support base. The output shaft of the motor is fixedly connected to the end face of the drive gear. One end of the guide rod is fixedly connected to the inner side of the fixed cylinder, and the other end of the guide rod is slidably mounted in a through hole on the end face of the transmission gear. A hexagonal connecting rod is fixedly mounted on the other end face of the transmission gear. The connecting rod cooperates with a connecting groove. The transmission gear cooperates with the drive gear. The motor is a gear reduction motor, and the motor is electrically connected to the button.

[0005] As a preferred technical solution of this utility model, a guide groove is provided on the side of one end of the support base, and a drive plate is slidably installed in the guide groove. The protruding part of the side of the drive plate passes through the guide groove and is fixedly connected to the side of one end of the push plate. The push plate is U-shaped, and the other end of the push plate is located on both sides of the transmission gear.

[0006] As a preferred technical solution of this utility model, the inner side of the other end of the support base is fixedly connected to one end of the spring piece, and the other end of the spring piece is fixedly connected to a steel ball. Several hemispherical positioning grooves are opened on the end face of the rotating ring. The number and position of the positioning grooves correspond to the bit, and the positioning grooves cooperate with the steel ball.

[0007] In a preferred embodiment of this invention, the grip has several finger grooves on its side. In another preferred embodiment, a light is fixedly mounted on the side of the support base away from the grip, and the light is electrically connected to the button.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model integrates several bits of different specifications on a rotating ring, which, together with a bearing, enables the rotating ring to rotate flexibly. When it is necessary to disassemble different types of bolts or screws, simply twist the rotating ring to quickly align the corresponding bit with the connecting rod. Unlike traditional electric screwdrivers, there is no need to repeatedly manually disassemble and install bits, which greatly reduces the operation steps and time for bit replacement. This makes the disassembly process of medical equipment parts smoother and effectively solves the cumbersome problem caused by frequent bit changes in traditional tools. It significantly improves disassembly efficiency and is especially suitable for scenarios involving the continuous disassembly of fasteners of multiple specifications in medical equipment maintenance. The overall structure adopts a compact connection design of the handle, support base, and fixed cylinder, making it small in size and easy for operators to operate flexibly in confined spaces such as operating rooms and treatment rooms.

[0009] 2. The drive plate can push the push plate to move along the guide groove, which in turn pushes the transmission gear to move, so that the transmission gear meshes or disengages with the drive gear, realizing the connection and separation of the connecting rod and the connecting groove. Through the cooperation of the spring, steel ball and positioning groove, automatic positioning can be achieved when switching bits, ensuring the stable position of the bit and facilitating the connection between the connecting rod and the connecting groove.

[0010] 3. The finger grooves allow the operator's fingers to naturally fit the handle, maintaining a comfortable grip posture and reducing the risk of operational errors caused by hand fatigue, thus improving the continuity and stability of operation. The lighting provides sufficient illumination in the dim environment inside the equipment, allowing the operator to clearly observe the disassembly parts and avoid misoperation due to poor visibility. This is especially effective in improving operational safety in scenarios where the internal structure of medical equipment is complex and the lighting is insufficient. Attached Figure Description

[0019] Example 1

[0020] like Figures 1 to 7 As shown, this utility model discloses a quick disassembly device for parts. The technical solution includes a handle 1, one end of which is fixedly connected to the side of a U-shaped support base 2. A battery 3 is fixedly installed inside the handle 1. A button 4 electrically connected to the battery 3 is fixedly installed on the side of the handle 1. Several finger grooves 14 are provided on the side of the handle 1. The finger grooves 14 allow the operator's fingers to naturally fit the handle 1, allowing the operator to maintain a comfortable grip posture, reducing the risk of operational errors caused by hand fatigue, and improving the continuity and stability of operation. The opposite side of the other end of the support base 2 is fixedly connected to the opposite side of the fixed cylinder 5. The fixed cylinder 5 is equipped with a switching mechanism 6 and a drive mechanism 7. A lighting lamp 15 is fixedly installed on the side of the support base 2 away from the handle 1. The lighting lamp 15 is electrically connected to the button 4. The lighting lamp 15 can provide sufficient lighting in the dim environment inside the equipment, so that the operator can clearly observe the disassembly part and avoid misoperation due to poor vision. Especially in the case of medical equipment with complex internal structure and insufficient light, it can effectively improve the safety of operation.

[0021] The switching mechanism 6 includes bearings 61, a rotating ring 62, bits 63, and connecting grooves 64. Two bearings 61 are provided; the inner rings of the two bearings 61 are fixedly connected to the sides of both ends of the fixed cylinder 5, and the outer rings of the two bearings 61 are fixedly connected to the inner side of the rotating ring 62. Several bits 63 are rotatably mounted on the side of the rotating ring 62. A hexagonal connecting groove 64 is formed on the end face of each bit 63 near the end of the rotating ring 62. A through groove that mates with the connecting groove 64 is formed on the side of the rotating ring 62. The inner side of the other end of the support base 2 is fixedly connected to one end of the spring piece 12. Next, a steel ball 11 is fixedly connected to the other end of the spring 12. Several hemispherical positioning grooves 13 are opened on the end face of the rotating ring 62. The number and position of the positioning grooves 13 correspond to the bit 63. The positioning grooves 13 cooperate with the steel ball 11. Through the cooperation of the spring 12, the steel ball 11 and the positioning grooves 13, automatic positioning can be achieved when switching bit 63, ensuring the stable position of bit 63 and facilitating the connection between the connecting rod 71 and the connecting groove 64. By integrating several bits 63 of different specifications on the rotating ring 62, the flexible rotation of the rotating ring 62 is achieved in conjunction with the bearing 61. When it is necessary to disassemble different types of bolts or screws, simply turn the rotating ring 62 to quickly align the corresponding bit 63 with the connecting rod 71. Unlike traditional electric screwdrivers, there is no need to repeatedly manually disassemble and install the bit, which greatly reduces the operation steps and time of bit replacement, making the disassembly process of medical equipment parts smoother. It effectively solves the cumbersome problem caused by frequent bit replacement of traditional tools, significantly improves disassembly efficiency, and is especially suitable for scenarios where multiple specifications of fasteners are disassembled continuously in medical equipment maintenance. The overall structure adopts a compact connection design of handle 1, support base 2, and fixed cylinder 5. It is small in size and easy for operators to operate flexibly in narrow environments such as operating rooms and treatment rooms.

[0022] The drive mechanism 7 includes a connecting rod 71, a drive gear 72, a transmission gear 73, a motor 74, and a guide rod 75. The motor 74 is fixedly mounted on the protruding part on the inner side of the support base 2. The output shaft of the motor 74 is fixedly connected to the end face of the drive gear 72. One end of the guide rod 75 is fixedly connected to the inner side of the fixed cylinder 5. The other end of the guide rod 75 is slidably mounted in the through hole on the end face of the transmission gear 73. A hexagonal connecting rod 71 is fixedly mounted on the other end face of the transmission gear 73. A guide groove 10 is provided on the side of one end of the support base 2. A drive plate 9 is slidably mounted in the guide groove 10. The protruding part on the side of the drive plate 9 passes through the guide groove 10 and is fixedly connected to the side of one end of the push plate 8. The push plate 8 is U-shaped, and the other end of the push plate 8 is located on both sides of the transmission gear 73. The drive plate 9 can push the push plate 8 to move along the guide groove 10, so that the push plate 8 pushes the transmission gear 73 to move, so that the transmission gear 73 meshes or separates from the drive gear 72, realizing the connection and separation of the connecting rod 71 and the connecting groove. The connecting rod 71 cooperates with the connecting groove 64, and the transmission gear 73 cooperates with the drive gear 72. The motor 74 is a gear reduction motor, and the motor 74 is electrically connected to the button 4.

[0023] The working principle of this utility model is as follows: The operator holds the handle 1, with their fingers naturally conforming to the finger grooves 14 on the side of the handle 1. The ergonomic design of the finger grooves 14 helps maintain a stable grip posture. Based on the specifications of the bolts or screws on the parts to be disassembled, a suitable bit 63 needs to be selected. The operator twists the rotating ring 62. Since the rotating ring 62 is connected to the fixed cylinder 5 through two bearings 61, the rotation process is flexible and smooth. When the rotating ring 62 rotates, the positioning groove 13 on its end face rotates along with it. When the positioning groove 13 corresponding to the target bit 63 rotates to correspond with the position of the steel ball 11 at the end of the spring piece 12 on the support base 2, the elastic force of the spring piece 12 causes the steel ball 11 to engage in the positioning groove 13, achieving precise positioning of the bit 63. This ensures that the connecting groove 64 of the bit 63 is aligned with the connecting rod 71 inside the fixed cylinder 5, completing the selection and switching of the bit 63. The operator then pushes the drive plate 9, which slides along the guide groove 10 on the support base 2, driving the connected U-shaped push plate 8 to move. The other end of the push plate 8 acts on both sides of the transmission gear 73, pushing the transmission gear 73 to slide along the guide rod 75 towards the rotating ring 62, so that the transmission gear 73 meshes with the driving gear 72. At the same time, the hexagonal connecting rod 71 on the end face of the transmission gear 73 passes through the through groove on the rotating ring 62 and is inserted into the hexagonal connecting groove 64 of the selected bit 63, thus realizing the connection of the power transmission path.

[0024] Pressing button 4 on handle 1 starts motor 74. The output shaft of motor 74 drives drive gear 72 to rotate. Drive gear 72 meshes with transmission gear 73, transmitting power to transmission gear 73. Transmission gear 73 rotates stably under the guidance of guide rod 75, and connecting rod 71 on its end face rotates synchronously. Through connecting groove 64, it drives bit 63 to rotate. By using bit 63 to engage with bolts or screws, the disassembly of parts is completed. Pressing button 4 simultaneously turns on light 15, providing sufficient illumination to ensure the operator can clearly observe the disassembly area and avoid operational errors. After disassembly, push drive plate 9 in the reverse direction to separate transmission gear 73 from drive gear 72. Connecting rod 71 disengages from connecting groove 64 of bit 63. Rotating ring 62 can then be turned again to switch bits 63 for the disassembly of the next part.
