In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0031] like Figures 1 to 4 As shown, applying the technical solution of this embodiment, the valve switch tool includes: a rod body 10, a sleeve 20 and an elastic member 30. The sleeve 20 is swingably arranged on the rod body 10, and the sleeve 20 has an accommodating hole 21 for accommodating the valve handle 60. The elastic member 30 is connected between the rod body 10 and the sleeve 20, and the direction of the force applied by the elastic member 30 to the sleeve 20 is opposite to the direction of the force applied by the valve handle 60 to the sleeve 20.

[0032] In this way, the operator can stand on the ground and hold the rod body 10 to sleeve the sleeve 20 outside the valve handle 60. The operator drives the sleeve 20 to rotate by controlling the movement of the rod body 10, so that the valve handle 60 in the sleeve 20 can rotate synchronously, so as to control the valve to control the on and off of the pipeline. The setting of the elastic member 30 is convenient for limiting the free rotation of the sleeve 20 relative to the rod body 10, so that the inner wall of the sleeve 20 can better abut against the valve handle 60, so as to drive the valve handle 60 to rotate through the sleeve 20. In addition, the setting of the elastic member 30 enables the sleeve 20 to remain stationary on the rod body 10 when the sleeve 20 is not sleeved on the valve handle 60, so as to facilitate the operation of the operator to sleeve the sleeve 20 on the valve handle 60. Therefore, the technical solution of this embodiment effectively solves the problem that the operator is more troublesome to control the valve in the related art, and there are safety risks.

[0033] It should be noted that when the sleeve 20 is not sleeved on the valve handle 60, the sleeve 20 is arranged at an angle to the rod body 10. In this embodiment, when the sleeve 20 is not sleeved on the valve handle 60, the sleeve 20 is arranged vertically to the rod body 10. In addition, by applying the technical solution of this embodiment, the operator can turn the valve handle 60 by using the valve opening and closing tool while standing on the ground, thereby reducing potential safety hazards and improving safety.

[0034] like Figures 1 to 4 As shown, the valve switch tool further includes a rotating shaft 40 rotatably arranged on the rod body 10, and the sleeve 20 is connected to the rotating shaft 40. The arrangement of the rotating shaft 40 facilitates the processing and assembly of the valve switch tool, and also facilitates the rotation of the sleeve 20 relative to the rod body 10. The first end of the sleeve 20 is provided with a first opening connected to the receiving hole 21. The arrangement of the first opening facilitates the valve handle 60 to enter the receiving hole 21, and facilitates the sleeve 20 to be sleeved on the valve handle 60. The distance between the first end of the sleeve 20 and the rotating shaft 40 is greater than the distance between the second end of the sleeve 20 and the rotating shaft 40. In this way, the first end of the sleeve 20 is farther than the rotating shaft 40, so that the rotating shaft 40 is farther than the first opening, and the distance between the rotating shaft 40 and the first opening is increased, so that the operator can save more effort when driving the sleeve 20 to rotate through the rod body 10.

[0035] In other embodiments, the distance between the first end of the sleeve 20 and the rotating shaft 40 is equal to the distance between the second end of the sleeve 20 and the rotating shaft 40 .

[0036] like Figures 1 to 4 As shown, the elastic member 30 includes a first elastic member 31 and a second elastic member 32. The first end of the sleeve 20 is provided with a first opening communicating with the accommodating hole 21, and the second end of the sleeve 20 is provided with a second opening communicating with the accommodating hole 21. The provision of the first opening and the second opening enables both ends of the sleeve 20 to be sleeved on the valve handle 60, so that the valve switch tool can provide more usage methods, making the use of the valve switch tool more flexible and convenient. The first elastic member 31 is connected between the first end of the sleeve 20 and the rod body 10, and the second elastic member 32 is connected between the second end of the sleeve 20 and the rod body 10. The provision of the first elastic member and the second elastic member 32 can better limit the free rotation of the sleeve 20 relative to the rod body 10, so that the inner wall of the sleeve 20 can better abut against the valve handle 60, so as to drive the valve handle 60 to rotate through the sleeve 20. In addition, both ends of the sleeve 20 are connected to the rod body 10 through the first elastic member 31 and the second elastic member 32 respectively, so that when the sleeve 20 is not sleeved on the valve handle 60, the sleeve 20 can better remain stationary on the rod body 10, so as to facilitate the operator to sleeve the sleeve 20 on the valve handle 60.

[0037] like Figures 1 to 4As shown, the valve switch tool also includes a rotating shaft 40 rotatably arranged on the rod body 10, and the sleeve 20 is connected to the rotating shaft 40. The arrangement of the rotating shaft 40 facilitates the processing and assembly of the valve switch tool, and also facilitates the rotation of the sleeve 20 relative to the rod body 10. The distance between the connection between the first elastic member 31 and the sleeve 20 and the rotating shaft 40 is greater than the distance between the connection between the second elastic member 32 and the sleeve 20 and the rotating shaft 40. In this way, when the sleeve 20 is not sleeved on the valve handle 60, both ends of the sleeve 20 can be subjected to elastic force, so as to keep the sleeve 20 at a position with a small angle with the ground, which is convenient for the operator to use. In addition, the first end of the sleeve 20 farther than the rotating shaft 40 can be subjected to a larger elastic force, so that the forces at both ends of the sleeve 20 are more balanced.

[0038] In other embodiments, the valve switch tool further comprises a rotating shaft 40 rotatably disposed on the rod body 10, and the sleeve 20 is connected to the rotating shaft 40. The distance between the connecting portion of the first elastic member 31 and the sleeve 20 and the rotating shaft 40 is equal to the distance between the connecting portion of the second elastic member 32 and the sleeve 20 and the rotating shaft 40.

[0039] like Figures 1 to 4 As shown, the rod body 10 is provided with a first connecting ring 13, and the first elastic member 31 is connected between the first connecting ring 13 and the first end of the sleeve 20. The first connecting ring 13 has a simple structure and is easy to process, and is convenient for connecting the first elastic member 31 to the rod body 10.

[0040] like Figures 1 to 4 As shown, the rod body 10 is provided with a second connecting ring 14, and the second elastic member 32 is connected between the second connecting ring 14 and the second end of the sleeve 20. The second connecting ring 14 has a simple structure, is easy to process, and is convenient for connecting the second elastic member 32 to the rod body 10. The first connecting ring 13 and the second connecting ring 14 are arranged at intervals along the axial direction of the rod body 10, and the first connecting ring 13 is located on the side of the second connecting ring 14 close to the sleeve 20. In this way, when the sleeve 20 is not sleeved on the valve handle 60, the elastic forces on both ends of the sleeve 20 are more balanced, so that the sleeve 20 is kept at a position with a smaller angle with the ground, which is convenient for operators to use.

[0041] like Figures 1 to 4 As shown, the rod body 10 includes a first rod body 11 and a second rod body 12 which are detachably connected, and the sleeve 20 and the elastic member 30 are both arranged on the first rod body 11. In this way, the operator can choose to use the first rod body 11 and the second rod body 12 or only the first rod body 11 according to the height of the valve, which is convenient for operation, improves flexibility during use, and improves adaptability.

[0042] In this embodiment, the diameters of the first rod body 11 and the second rod body 12 are both 2 cm, and the lengths of the first rod body 11 and the second rod body 12 are both 80 cm. The first rod body 11 and the second rod body 12 are detachably connected via threads.

[0043] like Figures 1 to 4 As shown, the rod body 10 includes a rod body 111 and a sphere 112 disposed at one end of the rod body 111, and the rotating shaft 40 is rotatably disposed on the sphere 112. The arrangement of the sphere 112 facilitates processing and installation of the rotating shaft 40. The rotating shaft 40 is a screw rod, and the valve switch tool further includes a nut, the screw rod is rotatably disposed on the rod body 10, and the nut can be threadedly matched with one end of the screw rod that is extended out of the rod body 10. The structure of the screw rod and the nut is simple and easy to process.

[0044] In this embodiment, the first rod body 11 includes a rod body 111 and a spherical body 112 disposed at one end of the rod body 111 .

[0045] In other embodiments, the rod body 10 includes a rod body 111 and a sphere 112 disposed at one end of the rod body 111, and the rotating shaft 40 is rotatably disposed on the sphere 112. Alternatively, the rotating shaft 40 is a screw rod, and the valve switch tool further includes a nut, the screw rod is rotatably disposed on the rod body 10, and the nut can be threadedly matched with one end of the screw rod that passes out of the rod body 10.

[0046] like Figures 1 to 4 As shown, the valve switch tool also includes a connector 50 for fixing the sleeve 20 on the rotating shaft 40. The arrangement of the connector 50 facilitates the connection between the sleeve 20 and the rotating shaft 40, so that when the rotating shaft 40 rotates, the sleeve 20 can be driven to swing through the connector 50.

[0047] like Figures 1 to 4 As shown, the connecting member 50 is a connecting plate, and there are two connecting plates. The two connecting plates are respectively fixedly connected to the two ends of the rotating shaft 40, and the two connecting plates are respectively fixedly connected to the two opposite sides of the sleeve 20. In this way, when the rotating shaft 40 rotates to drive the sleeve 20 to swing, the force on the sleeve 20 is more uniform, so that the sleeve 20 can more reliably drive the valve handle 60 to rotate.

[0048] In this embodiment, the cross section of the sleeve 20 is a rectangle, the width of the rectangle is 2 cm, and the height of the rectangle is 4 cm. The length of the connecting plate is 5 cm, the width is 1 cm, and the thickness is 0.2 cm. The connecting plate is welded to the rotating shaft 40. The first elastic member 31 is a first spring, the diameter of the first spring is 1.5 cm, and the length is 6 cm. The second elastic member 32 is a second spring, the diameter of the second spring is 0.8 cm, and the length is 3 cm.

[0049] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0050] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0051] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
