Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a multifunctional appliance. Background Art

[0002] In the daily care work of medical staff, tools such as scissors, grinding wheels for opening ampoules, and knives are all commonly used. Existing common tools are all separately installed. Therefore, medical staff need to carry a large number and variety of tools, which puts a lot of pressure on their pockets and reduces their comfort. At the same time, scissors, grinding wheels, and knives are all sharp instruments. When placed with other nursing supplies, they are not only inconvenient to use, but also prone to cross-infection. Because the tools carried on hand are placed in pockets and come into contact with each other, they need to be disinfected every day. However, due to the wide variety of tools, disinfection is often missed.

[0003] The multifunctional tools currently used by medical staff integrate tools such as scissors, grinding wheels, and cutters into a single pen. Specifically, the pen includes a pen holder with a connecting rod provided above the pen holder. The upper surface of the pen holder is provided with a groove, into which the scissors, grinding wheels, and cutters are placed. The connecting rod protects the scissors, grinding wheels, and cutters. When using the pen, the connecting rod needs to be disassembled from the pen holder to take out the required tools, making the installation and use of each tool very complicated. At the same time, since multiple tools are concentrated inside a pen, the overall size of the pen becomes larger, affecting portability and practicality. Utility Model Content

[0004] In view of this, the present invention provides a multifunctional tool to solve the problems of existing multifunctional tools being large in size and complicated in usage.

[0005] The utility model provides a multifunctional tool, comprising:

[0006] A shell, with a first cavity and a second cavity respectively provided at two ends thereof;

[0007] a scissor unit, slidably connected to the first cavity, the scissor unit having a use state of sliding out of the first cavity and a storage state of being arranged in the first cavity;

[0008] a grinding wheel unit, rotatably connected to the first cavity or the second cavity;

[0009] The tool unit is rotatably connected in the first cavity or the second cavity.

[0010] Beneficial effects: By integrating the scissor unit, the grinding wheel unit, and the cutter unit in different cavities within the housing, the thickness of this multi-functional tool can be reduced, enhancing the convenience of carrying. And when the scissor unit slides out of the first cavity, it can automatically transform into the usage state, thereby achieving the technical effect of enhancing the convenience of using the scissor unit.

[0011] In an alternative embodiment, the scissor unit includes:

[0012] A first body, the first body including a first blade and a handle fixedly connected;

[0013] A second body, cross-hinged with the first body, the second body including a second blade and a support portion fixedly connected;

[0014] A first elastic component, one end connected to the handle and the other end connected to the support portion;

[0015] A first limiting structure, connected to one side of the handle, the first limiting structure being slidably connected to the housing, the first limiting structure having a first state of being clamped with the housing and a second state of sliding out of the housing. In the first state, the first elastic component is in a compressed state, and the scissor unit is in the storage state; in the second state, the first elastic component is released from the compressed state, and the scissor unit is in the usage state.

[0016] Beneficial effects: When the first limiting structure is adjusted from the first state of being clamped with the housing to the second state of sliding out of the housing, the first limiting structure no longer applies pressure to the first elastic component. At this time, the first elastic component in the compressed state drives the first body and the second body to rotate and separate around the hinge position under the action of the elastic force, realizing the automatic conversion of the scissor unit from the storage state to the usage state. That is, when the first limiting structure is in the second state, the scissor unit can automatically pop out to form the usage state, thereby achieving the technical effect of enhancing the convenience of using the scissor unit.

[0017] In an alternative embodiment, the housing includes: a guiding space provided within the housing, and the first limiting structure is slidably connected to the guiding space;

[0018] A guiding through-hole provided on one side of the housing for accommodating the handle.

[0019] Beneficial effects: By providing a guiding space, it is possible to facilitate the limitation of the sliding path of the first limiting structure within the housing and improve the accuracy of the sliding trajectory of the first limiting structure. At the same time, the provision of the guiding through-hole enables the handle to slide along the guiding through-hole during the sliding process of the first limiting structure, so that when the scissor unit is in use, the handle can pop out of the guiding through-hole, and by driving the handle, the cross-cutting of the first blade and the second blade can be achieved.

[0020] In an alternative embodiment, the guiding space includes a first guiding channel and a second guiding channel;

[0021] The first limiting structure includes:

[0022] A first limiting portion, one end of which is connected to the handle, and the first limiting portion is slidably connected to the first guiding channel;

[0023] A second limiting portion, connected to the other end of the first limiting portion, the second limiting portion is slidably connected to the second guiding channel, and along the length direction perpendicular to the housing, the size of the second limiting portion is greater than the size of the first guiding channel; in the first state, the second limiting portion realizes the clamping relative to the first guiding channel, and in the second state, the first limiting portion slides out of the first guiding channel, and the second limiting portion slides out of the second guiding channel.

[0024] Beneficial effects: When the first limiting structure is located within the guiding space, the first limiting portion is located within the first guiding channel, and the second limiting portion is located within the second guiding channel. At the same time, the second limiting portion is located at the connection position of the first guiding channel and the second guiding channel. Since along the length direction perpendicular to the housing, the size of the second limiting portion is greater than the size of the first guiding channel, that is, the size of the second guiding channel is greater than the size of the first guiding channel, it is possible to form a step at the connection position of the first guiding channel and the second guiding channel, and the second limiting portion is clamped below the step, so that the second limiting portion cannot enter the first guiding channel from the second guiding channel, that is, the second limiting portion can apply pressure to the first elastic component through the handle, so that the first elastic component is in a compressed state. At this time, the scissor unit is in a stored state.

[0025] When the handle moves in a direction away from the first cavity, by driving the second limiting portion to slide through the first limiting portion until the second limiting portion leaves the second guiding channel, at this time, the second limiting portion is no longer limited by the first guiding channel and the second guiding channel. The first elastic component in the compressed state drives the handle to move in a direction away from the guiding through-hole under the action of the elastic force, so that the first blade and the second blade automatically move away from each other to form the use state of the scissor unit.

[0026] After the scissor unit is used, by compressing the handle, i.e., the first elastic component is in a compressed state, and it drives the first limiting portion and the second limiting portion to slide along the direction close to the first cavity, so that the first limiting portion is located in the first guiding channel, the second limiting portion is located in the second guiding channel, and under the pressure of the second limiting portion, the first elastic component can be in a compressed state, completing the storage of the scissor unit.

[0027] In an alternative embodiment, the first elastic component includes:

[0028] A telescopic structure, one end of which is connected to the handle and the other end is connected to the supporting portion;

[0029] An elastic member, sleeved outside the telescopic structure.

[0030] Beneficial effect: The telescopic structure can play a guiding role in the compression or elongation path of the elastic member, thereby achieving the technical effect of improving the accuracy of the telescopic trajectory of the elastic member.

[0031] In an alternative embodiment, the grinding wheel unit and / or the cutting tool unit includes:

[0032] A rotating body, rotatably connected in the second cavity through a rotating shaft;

[0033] A grinding wheel body and / or a cutting tool body, fixedly connected to the rotating body;

[0034] A fixing body, arranged on the rotating body and the housing, for fixing the position of the rotating body.

[0035] Beneficial effect: According to the needs of the grinding wheel body and the cutting tool body, the rotating body can drive the grinding wheel body and / or the cutting tool body to rotate into the second cavity to realize the storage of the grinding wheel body and the cutting tool body; or the rotating body can drive the grinding wheel body and / or the cutting tool body to rotate out of the second cavity to use the grinding wheel body and the cutting tool body. When the grinding wheel body and / or the cutting tool body rotate to be located inside or outside the housing, the position of the rotating body is fixed by the fixing body, so as to achieve the technical effect of improving the position stability of the rotating body.

[0036] In an alternative embodiment, the fixing body includes:

[0037] A fastening member, arranged on one side of the rotating body, and the fastening member is slidably connected to the housing;

[0038] A third clamping member, arranged on the rotating body, and the third clamping member is clamped with the fastening member to make the grinding wheel unit and / or the cutting tool unit in a use state;

[0039] The fourth snap - fitting member is provided on the rotating body and is spaced apart from the third snap - fitting member. The fourth snap - fitting member is snap - connected to the fastening member so that the grinding wheel unit and / or the cutting tool unit is in a stored state.

[0040] Advantageous effects: The third snap - fitting member and the fourth snap - fitting member are provided on the rotating body, and a fastening member that can cooperate with the third snap - fitting member and the fourth snap - fitting member. By controlling the sliding of the fastening member along the housing, the fastening member is inserted into the third snap - fitting member or the fastening member is inserted into the fourth snap - fitting member to fix the position of the rotating body, thereby achieving the technical effect of improving the position stability of the grinding wheel unit and / or the cutting tool unit in the stored state and the use state.

[0041] In an alternative embodiment, the grinding wheel body includes:

[0042] A first elastic structure is provided on one side of the rotating body. The first elastic structure includes an elastic body and a fifth snap - fitting member. The first elastic structure is connected to the rotating shaft. The first elastic structure is used to drive the rotating body to rotate to the use state when the fastening member slides away from the fourth snap - fitting member.

[0043] A second limiting structure is connected to one side of the rotating body and is spaced apart from the first elastic structure.

[0044] During the rotation of the rotating body into the housing, the first elastic structure undergoes elastic deformation. The second limiting structure has a connection state of being snap - connected to the fifth snap - fitting member, and the rotating body continues to rotate until the fourth snap - fitting member is snap - connected to the fastening member.

[0045] When the fastening member slides to leave the fourth snap - fitting member, the first elastic structure drives the rotating body to move to a state where the grinding wheel unit and / or the cutting tool unit is in the use state.

[0046] Advantageous effects: By providing the first elastic structure and the second limiting structure, during the rotation of the rotating body into the housing, the second limiting structure can be snap - connected to the fifth snap - fitting member and drive the movement of the fifth snap - fitting member, causing the elastic body to undergo elastic deformation and have an elastic force. When the rotating body moves to the stored state, the fastening member and the fourth snap - fitting member are snap - connected to fix the position of the rotating body, causing the elastic body to maintain the state of elastic deformation. When it is necessary to adjust the use state of the grinding wheel unit or the cutting tool unit, the fastening member disengages from the fourth snap - fitting member. At this time, the elastic body drives the second limiting structure to rotate in the direction of the rotating body rotating out of the housing under the action of the elastic force, and the grinding wheel unit and / or the cutting tool unit can be automatically ejected to the use state without manually rotating the rotating body, thereby achieving the technical effect of improving the simplicity of adjusting the use state of the grinding wheel unit and the cutting tool unit.

[0047] In an alternative embodiment, the grinding wheel body includes:

[0048] A fixing member connected to the rotating body;

[0049] A grinding wheel detachably connected below the fixing member.

[0050] Advantageous effects: Due to the detachable connection between the fixing member and the grinding wheel, when the grinding wheel is worn, it is convenient to replace and repair the grinding wheel.

[0051] In an alternative embodiment, the multifunctional tool includes:

[0052] A power supply device fixedly connected to the housing;

[0053] A clock connected to the power supply device, and the clock is arranged outside the housing;

[0054] And / or, a lighting lamp connected to the power supply device, and the lighting lamp is arranged outside the housing;

[0055] And / or, a control unit connected to the lighting lamp, and the control unit is arranged outside the housing;

[0056] And / or, a bottle opener arranged outside the housing and located between the first cavity and the second cavity.

And when medical staff need light, they can use this multifunctional tool for lighting, and the brightness of the lighting lamp can be controlled through the control unit. At the same time, the bottle opening operation can be realized through the bottle opener, which increases the types of tools of this multifunctional tool. And by adjusting the positions of the clock, the lighting lamp and the bottle opener on the housing, the space inside the housing can be fully utilized, reducing the thickness of the housing, so as to achieve the technical effect of improving the portability and usability of this multifunctional tool.

[0085] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0086] The following will be combined with Figures 1 to 15 , to describe the embodiments of the present utility model.

[0087] According to an embodiment of the present utility model, a multifunctional tool is provided, including:

[0088] A housing 1, with a first cavity and a second cavity respectively provided at both ends thereof;

[0089] A scissor unit 2, slidably connected in the first cavity, the scissor unit 2 having a use state of sliding out of the first cavity and a storage state provided in the first cavity;

[0090] A grinding wheel unit 3, rotatably connected in the first cavity or the second cavity;

[0091] A tool unit 4, rotatably connected in the first cavity or the second cavity.

[0092] In the multi-functional tool of this embodiment, by integrating the scissor unit 2, the grinding wheel unit 3, and the cutting tool unit 4 into different cavities on the housing 1, the thickness of the multi-functional tool can be reduced, and the convenience of carrying can be improved. At the same time, when the scissor unit 2 slides out of the first cavity, it can be automatically deformed into a use state, thereby achieving the technical effect of improving the convenience of using the scissor unit 2.

[0093] Among them, in this embodiment, both the grinding wheel unit 3 and the cutting tool unit 4 are located in the second cavity. Of course, in other embodiments, according to the different designs of the multi-functional tool, the positions of the scissor unit 2, the grinding wheel unit 3, and the cutting tool unit 4 can be adjusted.

[0094] Furthermore, the multi-functional tool is only the size of a ballpoint pen, so as to achieve the technical effect of being convenient to carry.

[0095] In addition, as shown in combination with Figure 5 and Figure 6 in this embodiment, the scissor unit 2 includes:

[0096] A first main body, the first main body includes a first blade 201 and a handle 202 that are fixedly connected;

[0097] A second main body, which is cross-hinged with the first main body, the second main body includes a second blade 203 and a support portion 204 that are fixedly connected;

[0098] A first elastic component, one end is connected to the handle 202, and the other end is connected to the support portion 204;

[0099] A first limiting structure, which is connected to one side of the handle 202, the first limiting structure is slidably connected to the housing 1, and the first limiting structure has a first state of being clamped with the housing 1 and a second state of sliding out of the housing 1. In the first state, the first elastic component is in a compressed state, and the scissor unit 2 is in a storage state. In the second state, the first elastic component is released from the compressed state, and the scissor unit 2 is in a use state. Among them, the support portion 204 can be set as a support block, which is located near the hinge position of the first main body and the second main body.

[0100] Based on this, when the first limiting structure is adjusted from the first state of being clamped with the housing 1 to the second state of sliding out of the housing 1, the first limiting structure no longer applies pressure to the first elastic component. At this time, the first elastic component in the compressed state drives the first main body and the second main body to rotate and separate around the hinge position under the action of the elastic force, realizing the automatic conversion of the scissor unit 2 from the storage state to the use state. That is, when the first limiting structure is in the second state, the scissor unit 2 can automatically pop out to form a use state, thereby achieving the technical effect of improving the convenience of using the scissor unit 2.

[0101] When in use, the operator can hold the handle 202 and the housing 1 to use the scissor unit 2 .

[0102] Furthermore, the tips of the first blade 201 and the second blade 203 are provided with arc chamfers, which are not easy to hurt the hands, thereby achieving the technical effect of improving the safety of the scissors unit 2.

[0103] In addition, preferably, the first body is cross-hinged with the second body through a hinge axis, and the shell 1 is provided with a horizontal groove at the corresponding position of the hinge axis, and the horizontal groove is along the length direction of the shell 1, that is, Figure 3 The horizontal arrangement shown is shown, with the hinge axis located within the horizontal groove. When the scissor unit 2 switches between the in-use state and the stowed state, the hinge axis can move along the length of the horizontal groove, thereby improving the movement stability of the scissor unit 2. When the scissor unit 2 is in use, the hinge axis is at the edge of the horizontal groove. The horizontal groove can limit the sliding distance of the scissor unit 2, preventing the scissor unit 2 from leaving the first cavity, thereby limiting the sliding range of the scissor unit 2.

[0104] In addition, combined Figure 4 As shown, in this embodiment, the housing 1 includes:

[0105] A guide space is provided in the housing 1, and the first limiting structure is slidably connected to the guide space;

[0106] The guide through hole 103 is provided on one side of the housing 1 and is used to accommodate the handle 202 .

[0107] By providing the guide space, it is possible to easily define the sliding path of the first limiting structure within the housing 1, thereby improving the accuracy of the sliding trajectory of the first limiting structure. At the same time, the provision of the guide hole 103 enables the handle 202 to slide along the guide hole 103 during the sliding process of the first limiting structure. Therefore, when the scissor unit 2 is in use, the handle 202 can be ejected from the guide hole 103, and by driving the handle 202, the first blade 201 and the second blade 203 can be cross-cut.

[0108] Among them, the guide hole 103 and the horizontal groove edge Figure 4 and Figure 5 As shown, the guide holes 103 are arranged at intervals in the vertical direction and are located above the horizontal slots.

[0109] Specifically, if Figure 1 As shown, when the scissor unit 2 is in the storage state, part of the bottom surface of the handle 202 is located at the top of the shell 1, and another part of the bottom surface of the handle 202 extends into the guide hole 103, and the guide hole 103 can limit the moving distance of the handle 202 to avoid excessive sliding of the scissor unit 2.

[0110] Among them, in combination with Figure 4 as shown, in this embodiment, the guiding space includes a first guiding channel 101 and a second guiding channel 102. The first limiting structure includes:

[0111] a first limiting portion 205, one end of which is connected to the handle 202, and the first limiting portion 205 is slidably connected to the first guiding channel 101;

[0112] a second limiting portion 206, connected to the other end of the first limiting portion 205, and the second limiting portion 206 is slidably connected to the second guiding channel 102. Along the length direction perpendicular to the housing 1, specifically in combination with Figure 4 as shown, the size of the second limiting portion 206 is larger than the size of the first guiding channel 101. In the first state, the second limiting portion 206 realizes the clamping relative to the first guiding channel 101. In the second state, the first limiting portion 205 slides out of the first guiding channel 101, and the second limiting portion 206 slides out of the second guiding channel 102.

[0113] Specifically, in combination with Figure 4 and Figure 5 as shown, when the scissor unit 2 is in the storage state, the first limiting portion 205 is located in the first guiding channel 101. Since the size of the second limiting portion 206 is larger than the size of the first guiding channel 101, the second limiting portion 206 is clamped in the step formed by the first guiding channel 101 and the second guiding channel 102, so that the second limiting portion 206 cannot move through the second guiding channel 102 into the first guiding channel 101, thereby limiting the position of the handle 202 through the second limiting portion 206, so that the handle 202 can always apply a pressure to the first elastic component, ensuring that the first elastic component is in a compressed state.

[0114] When the scissor unit 2 needs to be used, the operator can drive the handle 202 to drive the first limiting portion 205 to move along the first guiding channel 101 and the second limiting portion 206 to move along the second guiding channel 102 in a direction away from the first cavity, further driving the entire scissor unit 2 to move in a direction away from the first cavity. When the first limiting portion 205 slides out of the first guiding channel 101 and the second limiting portion 206 slides out of the second guiding channel 102, the handle 202 no longer applies a pressure to the first elastic component, and the first elastic component is released from the compressed state. Under the action of the elastic force, the first elastic component drives the handle 202 to pass through the guiding through-hole 103, so that the first blade 201 and the second blade 203 are automatically separated, forming the use state of the scissor unit 2, so as to improve the simplicity of using the scissor unit 2.

[0115] Further, the operator moves the driving handle 202 towards the direction close to the supporting part 204. At this time, the first elastic component can be compressed, so that the first blade 201 and the second blade 203 approach each other to achieve cutting. Then, under the action of the elastic force of the first elastic component, the first blade 201 and the second blade 203 are separated. Repeating this process, the cutting is completed.

[0116] When it is necessary to store the scissor unit 2, the operator presses down the handle 202 to apply a compressive force to the first elastic component through the handle 202. And the handle 202 drives the entire scissor unit 2 to move towards the direction close to the first cavity, so that the first limiting part 205 is located in the first guiding channel 101, and the second limiting part 206 is located in the second guiding channel 102. The second limiting part 206 can be clamped in the step formed by the first guiding channel 101 and the second guiding channel 102 to ensure that the first elastic component is in a compressed state, thus completing the storage of the scissor unit 2.

[0117] Wherein, both the first limiting part 205 and the second limiting part 206 are in the structure of limiting rods, so as to improve the structural simplicity of the first limiting part 205 and the second limiting part 206, thereby achieving the technical effect of improving the simplicity of processing the first limiting part 205 and the second limiting part 206.

[0118] Of course, in other embodiments, the shapes of the first limiting part 205 and the second limiting part 206 can also be adaptively adjusted according to the design and actual use of the multi-functional tool.

[0119] Meanwhile, in other embodiments, the first limiting structure can also be adjusted as needed. For example, the relative positions between the handle 202 and the housing 1 are fixed by a clamp, so that the handle 202 can apply a pressure to the first elastic component.

[0120] Preferably, as shown in Figure 6 and Figure 7 the first elastic component includes:

[0121] a telescopic structure with one end connected to the handle 202 and the other end connected to the supporting part 204.

[0122] an elastic member 208 sleeved outside the telescopic structure.

[0123] The telescopic structure can play a guiding role in the compression or elongation path of the elastic member 208, thereby achieving the technical effect of improving the accuracy of the telescopic trajectory of the elastic member 208.

[0124] Wherein, as shown in Figure 6As shown, the elastic member 208 is a spring set in an arc shape, located on the left side of the hinged position of the first blade 201 and the second blade 203. The telescopic structure is formed by two telescopic rods sleeved together, and the shape of the telescopic structure is the compression and elongation trajectory of the elastic member 208, both of which are arc-shaped.

[0125] Specifically, in combination with Figure 7 As shown, a chute 2073 is provided inside the first telescopic rod 2071. The second telescopic rod 2072 is located inside the chute 2073. The diameter of the chute 2073 is larger than the diameter of the second telescopic rod 2072, and the second telescopic rod 2072 can move along the length direction of the chute 2073.

[0126] Furthermore, a cover 2074 is provided at the notch of the chute 2073. The cover 2074 is sleeved outside the second telescopic rod 2072. A block 2075 is provided at the end of the second telescopic rod 2072 located inside the chute 2073. The diameter of the block 2075 is equal to the diameter of the chute 2073 and larger than the diameter of the second telescopic rod 2072. When the second telescopic rod 2072 moves towards the direction close to the cover 2074, the movement of the block 2075 can be blocked by the cover 2074, limiting the movement distance of the second telescopic rod 2072, so that the second telescopic rod 2072 always moves inside the chute 2073. The telescopic movement of the elastic member 208 drives the second telescopic rod 2072 in the length of the first telescopic rod 2071, achieving the technical effect of guiding the compression path and elongation path of the elastic member 208.

[0127] The structure of the tool unit 4 in this embodiment is the same as that of the grinding wheel unit 3. The tool unit 4 and the grinding wheel unit 3 are mirror - image arranged in the second cavity. The following description mainly takes the grinding wheel unit 3 as an example, and the specific structure of the tool unit 4 can be obtained by replacing the grinding wheel main body of the grinding wheel unit 3 with a tool main body.

[0128] In addition, in combination with Figure 8 and Figure 9 As shown, in this embodiment, the grinding wheel unit 3 includes:

[0129] A rotating main body 301, rotatably connected to the second cavity through a rotating shaft;

[0130] A grinding wheel main body, fixedly connected to the rotating main body 301;

[0131] A fixing main body, arranged on the rotating main body 301 and the housing 1, for fixing the position of the rotating main body 301. Among them, the rotating main body 301 can be a disc - shaped structure.

[0132] By setting that the rotating main body 301 can be rotatably connected within the second cavity, according to the needs of the grinding wheel main body and the rotating main body 301, the grinding wheel main body can be driven by the rotating main body 301 to rotate into the second cavity to realize the storage of the grinding wheel main body, or the grinding wheel main body can be driven by the rotating main body 301 to rotate out of the second cavity to realize the use of the grinding wheel main body. When the grinding wheel main body rotates to be located within the housing 1 or rotates out of the housing 1, the position of the rotating main body 301 is fixed by the fixing main body, so as to achieve the technical effect of improving the position stability of the rotating main body 301.

[0133] Preferably, in combination with Figures 9 to 13 as shown, the fixing main body includes:

[0134] A fastening member, arranged on one side of the rotating main body 301, and the fastening member is slidably connected to the housing 1;

[0135] A third clamping member 302, arranged on the rotating main body 301, and the third clamping member 302 is clamped with the fastening member to enable the grinding wheel unit 3 to be in a use state;

[0136] A fourth clamping member 303, arranged on the rotating main body 301 and spaced from the third clamping member 302, and the fourth clamping member 303 is clamped with the fastening member to enable the grinding wheel unit 3 to be in a storage state.

[0137] By arranging the third clamping member 302 and the fourth clamping member 303 on the rotating main body 301, and a fastening member that can cooperate with the third clamping member 302 and the fourth clamping member 303, by controlling the sliding of the fastening member along the housing 1, the fastening member is inserted into the third clamping member 302 or the fastening member is inserted into the fourth clamping member 303, so as to fix the position of the rotating main body 301, thereby achieving the technical effect of improving the position stability of the rotating main body 301 in the storage state and the use state.

[0138] Specifically, when the grinding wheel unit 3 is in the storage state, that is, when the grinding wheel unit 3 is within the second cavity, the fourth clamping member 303 of the rotating main body 301 is located directly below the fastening member, and the fastening member slides along the housing 1 to a position where it is clamped with the fourth clamping member 303, so that the rotating main body 301 cannot rotate, so as to fix the position of the rotating main body 301, thereby achieving the technical effect of improving the position stability of the rotating main body 301 in the storage state. When the rotating main body 301 does not need to be in the storage state, the fastening member can be slid out of the housing 1 from the position where it is clamped with the fourth clamping member 303, so that the rotating main body 301 can continue to rotate.

[0139] When the rotating body 301 is rotated to the use state, that is, the grinding wheel body is rotated to the desired position outside the housing 1, the third clamping member 302 of the rotating body 301 is located directly below the fastening member. The fastening member slides along the housing 1 to a position where it engages with the third clamping member 302, preventing the rotating body 301 from rotating. The position of the rotating body 301 is fixed, thereby achieving the technical effect of improving the positional stability of the rotating body 301 in the use state. When the rotating body 301 is no longer in use, that is, it needs to be rotated, the fastening member can be slid out along the housing 1 to release the fastening member from the third clamping member 302, allowing the rotating body 301 to continue rotating.

[0140] The third clamping member 302 and the fourth clamping member 303 are both clamping grooves, and the third clamping member 302 and the fourth clamping member 303 are arranged at intervals along the circumferential direction of the rotating body 301 .

[0141] Combine Figure 10 As shown, the fastening components include:

[0142] The buckle block 3051 has one end located in the second cavity and the other end passing through the housing 1 and located outside the housing 1 , and the buckle block 3051 can be buckled into the third clamping member 302 and the fourth clamping member 303 ;

[0143] The fixing portion 3052 is disposed in the second cavity. The fixing portion 3052 is provided with a fixing groove. The snap-fit block 3051 has the same cross-section as the fixing groove. The snap-fit block 3051 is located in the fixing groove and can slide along the fixing groove.

[0144] The driving portion 3053 is fixedly connected to the snap-fit block 3051 located outside the housing 1 , and is used to drive the snap-fit block 3051 to slide relative to the fixing portion 3052 .

[0145] When the fastening member is not fastened with the third clamping member 302 and the fourth clamping member 303, the fixing groove can provide friction to the fastening block 3051, limiting the fastening block 3051 to be located in the fixing groove, thereby preventing the fastening block 3051 from being driven downward by gravity and affecting the rotation of the rotating body 301, thereby achieving the technical effect of improving the position stability of the fastening block 3051.

[0146] Of course, in other embodiments, the fastening member may also be a screw, and the third clamping member 302 and the fourth clamping member 303 are both threaded holes, and the position of the rotating body 301 is fixed by threaded connection between the fastening member and the third clamping member 302 or the fastening member and the fourth clamping member 303. Compared with other embodiments, the fastening member and the third clamping member 302, as well as the fastening member and the fourth clamping member 303 in this embodiment are connected by sliding to fix the rotating body 301 in the storage state and the use state, thereby achieving the technical effect of improving the convenience of fixing the position of the rotating body 301.

[0147] In other embodiments, a rotating body 301, a grinding wheel body, and a fixing body may be provided only on the grinding wheel unit 3, and the tool unit 4 may be rotatably connected to the housing 1. Alternatively, a rotating body 301, a tool body, and a fixing body may be provided only on the tool unit 4, and the grinding wheel unit 3 may be rotatably connected to the housing 1.

[0148] In addition, in combination with Figure 9 and Figure 12 as shown, in this embodiment, the grinding wheel body includes:

[0149] A first elastic structure 306 is provided on one side of the rotating body 301. The first elastic structure 306 includes an elastic main body 3061 and a fifth engaging member 3062. The first elastic structure 306 is connected to the rotation axis of the rotating body 301.

[0150] A second limiting structure 307 is connected to one side of the rotating body 301 and is spaced from the first elastic structure 306.

[0151] During the process of the rotating body 301 rotating into the housing 1, the first elastic structure 306 undergoes elastic deformation, and the second limiting structure 307 has a connection state of engaging with the fifth engaging member 3062. The rotating body 301 continues to rotate until the fourth engaging member 303 engages with the fastening member.

[0152] When the fastening member slides to leave the fourth engaging member 303, the first elastic structure 306 drives the rotating body 301 to move until the grinding wheel unit 3 is in a use state.

[0153] By providing the first elastic structure 306 and the second limiting structure 307, and connecting the first elastic structure 306 to the rotation axis of the rotating body 301, when the rotating body 301 rotates into the housing 1, initially when the rotating body 301 rotates, the first elastic structure 306 does not rotate. When the second limiting structure 307 rotates to engage with the fifth engaging member 3062 of the first elastic structure 306, the rotating body 301 drives the fifth engaging member 3062 to rotate, thereby causing the elastic main body 3061 of the first elastic structure 306 to undergo elastic deformation and have a circumferential elastic force. When the grinding wheel body rotates to the storage state, the fastening member and the fourth engaging member 303 are engaged, which can maintain the state of elastic deformation of the elastic main body 3061. When it is necessary to adjust the grinding wheel body to the use state, the fastening member disengages from the fourth engaging member 303. At this time, the elastic main body 3061 drives the second limiting structure 307 to rotate in the direction of rotating out of the housing 1 under the action of the elastic force, and the grinding wheel unit 3 can be automatically ejected to the use state without manually rotating the rotating body 301 and the grinding wheel body, so as to achieve the technical effect of improving the simplicity of adjusting the use state of the grinding wheel unit 3.

[0154] Among them, the elastic body 3061 is a flat spiral spring, the fifth clamping member 3062 is a clamping groove formed by bending the elastic body 3061, and the second limiting structure 307 is a limiting rod.

[0155] Meanwhile, the tool body also includes a first elastic structure 306 and a second limiting structure 307, whose structures and working principles are the same as those of the grinding wheel body, and will not be elaborated here.

Wherein, both ends of the rotating shaft are provided with threads, and the position of the rotating shaft is fixed by screwing nuts onto the rotating shaft.

[0160] By detachably connecting the first fixing member 308 and the grinding wheel 304, it is convenient to replace and repair the grinding wheel 304 when the grinding wheel 304 is worn.

[0161] In addition, as shown in Figure 14 and Figure 15 , the tool body includes:

[0162] A second fixing member 401, connected to the rotating body 301.

[0163] A blade 402, detachably connected to one side of the second fixing member 401, so as to facilitate the replacement and repair of the blade 402 according to the wear of the blade 402.

[0170] By integrating the clock 5, the lighting lamp 6 and the bottle opener 7, it is convenient for medical staff to check the time. And when the medical staff needs light, they can control the lighting lamp 6 to turn on through the control unit, and the multifunctional tool is used for lighting. At the same time, the bottle opening operation can also be realized through the bottle opener 7, which increases the types of tools of the multifunctional tool.

[0171] Specifically, the clock 5 is provided on the outer surface of one side wall of the housing 1, the lighting lamp 6 is provided on the outer surface of the bottom wall of the housing 1, and an external accommodation space is provided on the housing 1 near the bottom. The accommodation space is located between the first cavity and the second cavity, and the bottle opener 7 is provided at this accommodation space. By designing different positions of the clock 5, the lighting lamp 6 and the bottle opener 7 on the housing 1, the space inside the housing 1 can be fully utilized, and the thickness of the housing 1 can be reduced, so as to achieve the technical effect of improving the portability and usability of the multifunctional tool.

[0172] Among them, the power supply device 8 is provided with a charging port, which is provided inside the housing 1 and is close to the first cavity. One side of the charging port is communicated with the outside. When the power of the power supply device 8 is insufficient, the power supply device 8 can be charged through the charging port.
