In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0045] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be replaceably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] The embodiments of the present application disclose a detachable handle body and an operating handle.

[0047] Please refer to Figure 1 One embodiment of the detachable handle body and operating handle provided in the embodiments of the present application includes:

[0048] The first handle shell 11, the second handle shell 12 engaged with the first handle shell 11 in the first direction, and the locking structure 2.

[0049] The first handle shell 11 and the second handle shell 12 are common shell structures, wherein the first direction can be understood as the left-right direction, the first handle shell 11 is a left shell, and the second handle shell 12 is a right shell.

[0050] The locking structure 2 comprises a limiting through groove 22, a locking block 23, and a fastener 21.

[0051] The limiting through groove 22 is arranged in the first handle shell 11 or the second handle shell 12 along a second direction perpendicular to the first direction; it can be understood that the slot opening of the limiting through groove 22 is oriented in the second direction perpendicular to the first direction, so as to change the locking direction.

[0052] The locking block 23 is movably arranged in the limiting through groove 22 along the second direction and is provided with a first inclined surface 231 in the first direction; the limiting through groove 22 is provided with a second inclined surface 221 matched with the first inclined surface 231; the fastener 21 detachably connects the locking block 23 with the first handle shell 11 or the second handle shell 12 and is used for adjusting the displacement of the locking block 23 in the second direction to the mutual extrusion of the first inclined surface 231 and the second inclined surface 221, so as to lock the first handle shell 11 and the second handle shell 12.

[0053] When the number of the locking structure 2 is multiple, the limiting through grooves 22 of all the locking structures 2 are arranged in the same handle shell or are arranged in two handle shells respectively.

[0054] The working principle of the locking is as follows:

[0055] After the first handle shell 11 and the second handle shell 12 are positioned and connected, the locking block 23 is placed in the limiting through groove 22 and is fastened by the fastener 21;

[0056] Taking the case that the limiting through groove 22 is arranged in the first handle shell 11, the fastener 21 connects the second handle shell 12 and the locking block 23, when the locking block 23 is moved to a certain displacement by operating the fastener 21 (i.e. moving in the direction of passing through the limiting through groove 22), the first inclined surface 231 is just extruded with the second inclined surface 221, at this time, an acting force is provided to lock the first handle shell 11 and the second handle shell 12 together; if the locking block 23 is continuously moved, the extrusion force of the first inclined surface 231 and the second inclined surface 221 will increase and the relative displacement of the first inclined surface 231 and the second inclined surface 221 will occur, so as to further press the first handle shell 11 and the second handle shell 12 together, the change of the displacement corresponds to the change of the pressing degree, so that the tightness of the combination of the first handle shell 11 and the second handle shell 12 is adjustable.

[0057] The detachable handle body designed in the application has the following beneficial effects:

[0058] 1. By changing the direction of locking, the locking structure 2 is ingeniously designed inside the handle body, which not only effectively improves the appearance of the product, but also makes the overall design more compact and integrated.

[0059] 2. By using the locking block 23 to assist in locking operation, this design allows the locking block 23 to be manufactured independently of other components. In this way, it is not necessary to integrate the locking block 23 with the first handle shell 11 and the second locking shell, thereby significantly reducing the dependence on high-precision machining technology.

[0060] 3. By finely adjusting the displacement of the locking block 23 in the second direction, the first inclined surface 231 of the locking block 23 can be tightly pressed against the second inclined surface 221 of the limiting through slot 22, thereby achieving the purpose of locking the first handle shell 11 and the second handle shell 12. This design allows users to easily change the degree of mutual pressing between the first inclined surface 231 and the second inclined surface 221 through simple displacement adjustment, thereby achieving adjustable tightness of the first handle shell 11 and the second handle shell 12. In this way, the tightness between the handle shells can be adjusted according to usage habits and needs, ensuring comfort and convenience of operation.

[0061] The above is an embodiment of a detachable handle body provided by the present application, and the following is an embodiment of a detachable handle body provided by the present application, please refer to Figures 1 to 4 .

[0062] Based on the above embodiment one:

[0063] Further, as shown in Figure 1 and Figure 2 , at least one end of the first handle shell 11 or the second handle shell is provided with a step portion 13; the limiting through slot 22 is provided in the step portion 13; and the first handle shell 11 or the second handle shell 12 is provided with a connecting boss 14 on one side of the limiting through slot 22, for connecting the fastener 21.

[0064] This design makes the position of the limiting through slot 22 more flexible, and can make full use of the space inside the handle shell. At the same time, the setting of the connecting boss 14 also provides convenience for the installation of the fastener 21. In actual application, this design can make the fastener 21 more stably connect the locking block 23 and the corresponding handle shell, enhancing the stability and durability of the whole. In addition, the setting of the step portion 13 also helps to improve the structural strength of the handle shell, making it more capable of bearing external forces.

[0065] Further, as shown in Figure 1 and Figure 2As shown, the fastener 21 is a threaded rod with a threaded rod portion and a connecting head portion; the lock block 23 is provided with a through hole for the threaded rod portion to pass through; the first handle shell 11 or the second handle shell 12 is provided with a threaded hole for screwing with the threaded rod portion; and the connecting head portion is in contact with the lock block 23.

[0066] The threaded rod design is not only simple in structure, but also easy to operate. Users can adjust the position of the lock block 23 in the limiting slot 22 by rotating the fastener 21, thereby achieving fine control of the locking degree of the first handle shell 11 and the second handle shell 12. This design not only improves the convenience of use, but also helps to ensure the stability and reliability of the handle body in different application scenarios. In addition, the cooperation of the threaded rod and the threaded hole also has good self-locking performance, which can effectively prevent the lock block 23 from loosening during use, further enhancing the durability and safety of the handle body.

[0067] The fastener 21 can be a screw, bolt, etc. These fasteners 21 are easy to purchase and low in cost on the market, which helps to reduce the manufacturing cost of the entire handle body. At the same time, the connection mode between the fastener 21 and the lock block 23 and the handle shell also has a certain universality, which is convenient for subsequent maintenance and replacement operations.

[0068] Further, as shown in Figure 4 The locking structure 2 is at least two, respectively located at both ends of the first handle shell 11 and the second handle shell 12. In actual use, four can be designed, two at each end.

[0069] This design can further enhance the stability and locking effect of the handle body. When both ends are provided with the locking structure 2, even if one end is subjected to a large external force, the locking structure 2 at the other end can still maintain the close combination of the handle shells, thereby avoiding the problem of loosening or falling off due to excessive force on one end. In addition, the arrangement of multiple locking structures 2 also makes the force on the handle body more uniform in different directions, improving the overall carrying capacity and service life. In actual application, this design can be applied to more complex use environments, providing users with a more stable and reliable use experience.

[0070] Further, as shown in Figure 1 and Figure 2 The lock block 23 is a wedge-shaped block, and the wedge-shaped block design makes the lock block 23 have at least a first inclined surface 231 to cooperate with a second inclined surface 221. Of course, it can also be a trapezoidal block design.

[0071] The wedge-shaped or trapezoidal block design not only facilitates processing and manufacturing, but also ensures stable movement of the locking block 23 in the limiting groove 22. At the same time, the cooperation between the first inclined surface 231 and the second inclined surface 221 is more close, thereby improving the locking force and stability of the locking structure 2. In actual application, this design can make the handle shell more firmly connected together, avoiding the safety hazard caused by loosening.

[0072] As shown in Figure 3 and Figure 6 , the application also discloses an operating handle, which comprises a detachable handle body, a control board 19 and a first operating switch 31.

[0073] The control board 19 is installed in the detachable handle body; the operating switch is installed on the detachable handle body and connected with the control board 19.

[0074] The first operating switch 31 can be a push switch, a toggle switch or a slide switch of different types to meet the use habits and needs of different users. The control board 19 as the core control component of the operating handle responds to the corresponding operation of the first operating switch 31 and sends a corresponding control signal to control the instrument.

[0075] Further, as shown in Figure 3 , Figure 4 and Figure 6 , it further comprises a second operating switch 32, which is installed on the detachable handle body and arranged opposite to the first operating switch 31 (the first operating switch 31 and the second operating switch 32 are arranged on two sides respectively). The design of the double operating switches not only improves the flexibility of operation, but also enhances the user experience. In actual application, the user can choose to use the first operating switch 31 or the second operating switch 32 for operation according to needs, or operate both switches at the same time to realize specific functions. This design makes the operating handle more in line with the ergonomic principle, reducing the fatigue of the user during long-time use.

[0076] Further, as shown in Figure 6 , the control board 19 is connected with the second operating switch 32 for sending a control signal when the first operating switch 31 and the second operating switch 32 are operated at the same time. Under this design, the second operating switch 32 is used as a protection switch, and the control board 19 sends a control signal to control the instrument to run only when both operating switches are operated at the same time (for example, pressed at the same time), so as to avoid misoperation.

[0077] Further, as shown in Figure 3As shown, the first operation switch 31 is a long strip switch. This design not only facilitates user operation, but also improves the accuracy of operation. The stroke of the long strip switch is relatively long, and the user needs to exert a certain force to trigger the switch, which to some extent avoids the possibility of accidental triggering. At the same time, the shape of the long strip switch is more in line with the contour of the human finger, making the user more comfortable and labor-saving when operating.

[0078] Further, as shown, Figure 3 The position of the detachable handle body surface below the first operation switch 31 is provided with a support guard plate 17 (the distance between the end of the support guard plate 17 and the surface of the detachable handle body is greater than the distance between the operation end of the first operation switch 31 and the surface of the detachable handle body, or it is understood that the support guard plate 17 is higher than the operation end of the first operation switch 31). This design not only protects the operation switch from damage caused by external impact, but also improves the safety of user operation. In actual application, the user may touch the switch due to improper operation or accidental circumstances, which may cause damage to the switch or accidental triggering. With the protection of the support guard plate 17, these problems can be effectively avoided. At the same time, the support guard plate 17 can be used to provide a support point for the hand when holding the handle, avoiding the hand from falling off due to poor grip.

[0079] Further, as shown, Figure 5 It also includes an electrical connector 18 installed at one end of the detachable handle body for docking with the handle mounting seat (not shown in the figure); in order to improve the docking reliability, as shown, Figure 3 One end of the detachable handle body (for example, the lower end, the end of the handle mounting seat is the lower end) is provided with a first docking chamber 15 (the first docking chamber 15 can be separated by the step part 13 located at one end of the first handle shell 11 and the second handle shell 12), and the first docking chamber 15 is used for inserting the handle mounting seat. When the handle mounting seat is inserted in place, the electrical connector 18 is electrically connected with the handle mounting seat.

[0080] As shown, Figure 4 In order to improve the docking reliability, the other end of the detachable handle body (for example, the lower end, the other end of the instrument is the upper end) is provided with a second docking chamber 16 (the second docking chamber 16 can be separated by the step part 13 located at the other end of the first handle shell 11 and the second handle shell 12), and the first docking chamber 15 is used for inserting the docking part of the instrument. The second docking chamber 16 for docking the instrument can increase the design of the cover plate 4, which covers the locking structure 2 and plays a certain protective role.

[0081] Such a design enables the operating handle to be connected and communicate with different devices or instruments, thereby realizing more extensive application scenarios and flexibility. In actual application, a user can select different electrical connectors 18 to connect different devices or instruments according to needs, so as to meet different use requirements.

[0082] The detachable handle body and the operating handle provided by the application are described in detail above. For those skilled in the art, the specific implementation and application range can be changed according to the idea of the embodiments of the application. In summary, the content of the specification should not be understood as a limitation of the application.
