[0004] (I) Purpose of the utility model

[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a novel handle with a lock card. The utility model can easily adjust the required handle rotation angle and easily release the locking angle.

[0006] (II) Technical solution

[0007] In order to solve the above problems, the utility model provides a novel handle with a lock, comprising a fixed handle and a movable handle, wherein the fixed handle is rotatably connected to the movable handle through a rotating shaft and a torsion spring;

[0008] A limiting mechanism is provided between the fixed handle and the movable handle, so as to limit the position of the fixed handle and the movable handle after they are close to each other.

[0009] Preferably, the limit mechanism includes a movable rack, a limit switch, a rotating shaft and a spring. A through opening is opened on the fixed handle, the limit switch passes through the through opening, and is rotatably connected to the fixed handle through a rotating shaft. The limit switch is connected to the inner wall of the through opening through a spring, one end of the movable rack is fixedly connected to the movable handle, and the limit switch is provided with inclined teeth near one end of the movable rack to adapt to the movable rack to limit itself after it continuously approaches the fixed handle.

[0010] Preferably, one end of the limit switch away from the movable rack is fixedly connected to a pressing rod.

[0011] Preferably, a rubber sleeve is fixedly mounted on the pressing rod.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] When the movable handle rotates continuously toward the fixed handle, the movable rack rotates continuously toward the fixed handle and slides continuously with the limit switch to self-adaptively position the movable handle after rotation; the doctor's hands can be freed to achieve the desired effect; the operation is more convenient for the doctor; high reliability: a very high reliability can be achieved through a simple mechanical structure; by pressing the pressing rod, the fixed handle can be rotated, the limit on the movable rack can be released, and the movable handle can be automatically rotated and separated.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] like Figure 1-3 As shown, the utility model provides a novel handle with a lock, comprising a fixed handle 1 and a movable handle 2, wherein the fixed handle 1 is rotatably connected to the movable handle 2 via a rotating shaft 3 and a torsion spring 4;

[0020] A limiting mechanism 5 is provided between the fixed handle 1 and the movable handle 2 for limiting the position of the fixed handle 1 and the movable handle 2 after they are close to each other.

[0021] Under the action of the torsion spring 4, after the movable handle 2 approaches the fixed handle 1, the torsion spring 4 recovers, which facilitates the movable handle 2 to rotate and separate from the fixed handle 1 quickly, thereby making the chuck installed on the handle separate instantly during use, reducing the adhesion of the chuck due to separation when clamping the tissue.

[0022] In an optional embodiment, the limit mechanism 5 includes a movable rack 51, a limit switch 52, a rotating shaft 53 and a spring 54. A through opening is opened on the fixed handle 2, the limit switch 52 passes through the through opening, and is rotatably connected to the fixed handle 1 through the rotating shaft 53. The limit switch 52 is connected to the inner wall of the through opening through the spring 54. One end of the movable rack 51 is fixedly connected to the movable handle 2. The limit switch 52 is provided with inclined teeth near one end of the movable rack 51 to adapt to the movable rack 51 to limit itself after it continuously approaches the fixed handle 1.

[0023] It should be noted that the through-port serves to accommodate the movable rack 51 .

[0024] In an optional embodiment, one end of the limit switch 52 away from the movable rack 51 is fixedly connected to a pressing rod 55 .

[0025] It should be noted that, under the action of the pressing rod 55 , by pressing the pressing rod 55 , the rotating shaft 53 is rotated as the axis, so that the limit switch 52 is rotated to release the positioning of the movable rack 51 .

[0026] In an optional embodiment, a rubber sleeve is fixedly mounted on the pressing rod 55 .

[0027] It should be noted that the rubber sleeve increases the comfort during pressing.

[0028] In the utility model, when the movable handle 2 is continuously rotated toward the fixed handle 1, the movable rack 51 is continuously rotated toward the fixed handle 1, and continuously slides with the limit switch 52 to self-adaptively position the movable handle 2 after rotation; the doctor's hands can be freed to achieve the use effect; the doctor can perform surgery more conveniently; high reliability: through a simple mechanical structure, very high reliability can be achieved; by pressing the pressing rod 55, the fixed handle 1 is facilitated to rotate, the limit of the movable rack 51 is released, and the movable handle 2 is facilitated to automatically rotate and separate.

[0029] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
