However, screw terminal and handle are exposed to device external and may stop healthcare givers's for Medical Devices Operation by human hand, and the objects such as clothes, perfusion tube, appendix for being easy to scratch healthcare givers, cause inconvenience in use.

Utility model content

Technical solutions of the utility model provide a kind of Medical Devices for above situation to solve the above-mentioned problems Quick Release screw, the Quick Release screw include: main body and handle, and the main body is in cylindrical shape, the side of the main body Face has external screw thread, and the upper end of the main body has holding tank, shaft channel there are two tools on the side wall of the holding tank, and two Shaft channel is facing each other, and the handle is in the shape of semicircular ring, and the both ends of the handle are respectively provided with shaft, two shaft phases Mutual face, the shaft are inserted into the shaft channel.

Further, the outer edge of the holding tank also has notch, and the notch is located between two shaft channels.

Further, the holding tank is annulus shape.

Further, the notch is two, and two notches are facing each other, the line of two notches and two shaft channels Line is mutually perpendicular to.

Further, the center of the main body upper end also has locked groove, and the locked groove can be regular polygon or ten Font.

Further, the lower end of the main body has conical tip.

Further, the middle part of the handle has anti-skid chequer.

After adopting the above technical scheme, the effect of the utility model is: the Quick Release screw with above structure, it not only can be with Realize the operation of Quick Release and fast-assembling, and due to not having screw terminal, handle can be hidden in main body, therefore can be greatlyd save Space will not scratch external object in equipment use process, and use is very convenient.

Detailed description of the invention

Fig. 1 is the schematic diagram of the Quick Release screw of the prior art；

Fig. 2 be the utility model relates to Quick Release screw schematic diagram；

Fig. 3 be the utility model relates to main body schematic diagram；

Fig. 4 be the utility model relates to handle schematic diagram.

Specific embodiment

Technical solutions of the utility model are further described below by embodiment:

The utility model provides a kind of Quick Release screw of Medical Devices, as shown in Fig. 2, Quick Release screw includes: 1 He of main body Handle 2, handle 2 are rotatably mounted to the upper end of main body 1.Specifically, main as shown in figure 3, main body 1 is in cylindrical shape The side of body 1 has external screw thread 11, and the lower end of main body 1 has conical tip 12, and the upper end of main body 1 has holding tank 13, Hand 2 is in the shape of semicircular ring, and handle 2 is rotatably mounted in holding tank 13.In the present embodiment, Quick Release screw is self tapping spiral shell Silk, therefore it is provided with conical tip 12, in other embodiments, Quick Release screw may be flat screw, be not provided with justifying Cone point 12.When user needs to remove screw from the device, it is only necessary to which swing handle 2 takes handle 2 from holding tank 13 Out, the direction for being re-directed towards unlock screw, which turns handle 2, rotates screw, and the dismantling operation of screw can be completed.When fixing spiral shell After silk, handle 2 can be placed in holding tank 13, the space of device external will not be occupied.

Specifically, incorporated by reference to shown in Fig. 3 and Fig. 4, there are two shaft channels 131, two to turn for tool on the side wall of holding tank 13 Axis channel 131 is facing each other, and the both ends of handle 2 are respectively provided with shaft 21, and two shafts 21 are facing each other, and shaft 21 is inserted into shaft In channel 131.By the cooperation of shaft 21 and shaft channel 131, the rotation operation of handle 2 may be implemented.

More specifically, the outer edge of holding tank 13 also has a notch 132, notch 132 be located at two shaft channels 131 it Between.User can place a finger on the position of notch 132, and handle 2 is taken out from holding tank 13, easy to use.

More specifically, holding tank 13 is annulus shape.In this way, handle 2 can be placed on any of holding tank 13 by user On one side, more convenient to use.

More specifically, notch 132 is two, two notches 132 are facing each other, the line of two notches 132 with two turns The line of axis channel 131 is mutually perpendicular to.In this way, user can pass through notch regardless of handle 2 is located at which side of holding tank 13 132 more easily take out handle 2.

Specifically, with continued reference to FIG. 3, the center of 1 upper end of main body also has locked groove 14, locked groove 14 can be positive more Side shape or cross.When handle 2 damages, locked groove 14 can cooperate with screwdriver, for dismantling screw.In the present embodiment, Locked groove 14 is regular hexagon.

Specifically, with continued reference to FIG. 4, the middle part of handle 2 has anti-skid chequer 22.Anti-skid chequer 22 can be to avoid due to user Hand is wet and slippery and the problem of leading to operation failure.

As it can be seen that the Quick Release screw with above structure, not only may be implemented the operation of Quick Release and fast-assembling, but also due to not With screw terminal, handle can be hidden in main body, therefore can greatly save space, will not be scratched in equipment use process outer Boundary's object, use are very convenient.

It is emphasized that term " first ", " second ", " third " in the utility model are used for description purposes only, and It cannot be understood as indicating or implying relative importance or implicitly indicate the quantity of indicated technical characteristic.It defines as a result, " first ", " second ", " third " feature can explicitly or implicitly include at least one of the features.Description of the invention In, the meaning of " plurality " is at least two, such as two, three etc., unless otherwise specifically defined.The utility model is real The directional instruction (such as up, down, left, right, before and after ...) of institute in example is applied to be only used for explaining each portion under a certain particular pose Relative positional relationship, motion conditions between part etc., if the particular pose changes, directionality instruction is also corresponding Ground changes correspondingly.

Embodiment described above, only the preferred embodiments of the utility model, are not the implementation model to limit the utility model It encloses, therefore all equivalent change or modifications done according to structure, feature and principle described in present utility model application the scope of the patents, it should all It is included in the scope of the utility model patent application.
