[0029] The present application provides a wrench and an actuator. In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 1 As shown, the wrench includes a wrench body 10 and a wrench handle, wherein the wrench handle includes a first handle 20 and a second handle 30. The first handle 20 is fixedly connected to or integrally formed with the wrench body 10. In the illustrated embodiment, the length of the first handle 20 is less than the length of the second handle 30. Alternatively, the length of the first handle 20 may be equal to or greater than the length of the second handle 30.

[0031] like Figure 2 and Figure 3As shown, the first handle 20 is provided with a first connection portion 201 , and the second handle 30 is provided with a second connection portion 301 . The first connection portion 201 and the second connection portion 301 can be detachably connected, so that the first handle 20 and the second handle 30 can be detachably connected.

[0032] When the above-mentioned wrench needs to be rotated, the second connection part 301 of the second handle 30 can be connected to the first connection part 201 of the first wrench, so that the total length of the wrench handle can be extended, thereby making the operation of the lever arm larger and more labor-saving. When the rotation is completed, the second handle 30 can be removed from the first handle 20 for separate storage.

[0033] Specifically, the detachable connection method between the first connection part 201 and the second connection part 301 includes but is not limited to plug-in connection, snap-on connection, threaded connection, etc.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the first connection portion 201 and the second connection portion 301 can be a socket, and one can be a plug that fits into the socket. The plug and socket can be plugged into each other, so that the first handle 20 and the second handle 30 can be connected and disconnected by simply plugging and unplugging, which is relatively convenient. In the illustrated embodiment, the first connection portion 201 is a socket and the second connection portion 301 is a plug. Alternatively, the first connection portion 201 can be a plug and the second connection portion 301 can be a socket.

[0035] Specifically, such as Figure 2 As shown, one end of the jack is provided with an opening for inserting the plug, and the jack includes a rotation-limiting hole section 201a. Figure 3 As shown, the plug post includes a rotation-limiting column segment 301a that is adapted to fit within the rotation-limiting hole segment 201a. Specifically, the cross-sectional outer contour of the rotation-limiting column segment 301a is similar to the cross-sectional inner contour of the rotation-limiting hole segment 201a. To ensure assembly, the cross-sectional outer contour of the rotation-limiting column segment 301a is slightly smaller than the cross-sectional inner contour of the rotation-limiting hole segment 201a. The cross-sectional outer contour of the rotation-limiting column segment 301a is non-circular, for example, a regular hexagon, preventing the rotation-limiting column segment 301a from rotating within the rotation-limiting hole segment 201a.

[0036] Specifically, such as Figure 2 As shown, the jack includes a guide hole section 201b, which is located at one end of the rotation-limiting hole section 201a close to the hole opening, and the plug post includes a guide post section 301b adapted to the guide hole section 201b. Figure 3As shown, the plug column includes a guide column segment 301b adapted to the guide hole segment 201b, that is, the cross-sectional outer contour shape of the guide column segment 301b and the cross-sectional inner contour shape of the guide hole segment 201b are similar to each other, and in order to ensure assemblability, the cross-sectional outer contour size of the guide column segment 301b should be slightly smaller than the cross-sectional inner contour size of the guide hole segment 201b. The cross-sectional outer contour shape of the guide column segment 301b is non-circular, for example, it can be a square. When the rotation-limiting column segment 301a is inserted into the rotation-limiting hole segment 201a, the guide hole segment 201b and the guide column segment 301b cooperate with each other to guide the insertion direction, thereby avoiding the situation of being inserted crookedly and stuck. The radial dimension of the cross-sectional outer contour of the guide column segment 301b is larger than the radial dimension of the cross-sectional outer contour of the rotation-limiting column segment 301a.

[0037] Specifically, such as Figure 3 As shown, the first handle 20 or the second handle 30 provided with the plug-in column includes a main body 302 and an insert 303. In the illustrated embodiment, the second handle 30 is provided with the plug-in column, and the second handle 30 includes a main body 302 and an insert 303. The main body 302 is provided with an embedding hole 302a for embedding the insert 303. The cross-sectional outer contour of the insert 303 is non-circular, for example, it can be a regular hexagon. One end of the insert 303 protrudes from the embedding hole 302a to form the above-mentioned rotation-limiting column segment 301a. One end of the main body 302 is provided with the above-mentioned guide column segment 301b, that is, the above-mentioned guide column segment 301b is formed on the main body 302. In this way, the main body 302 and the insert 303 can be processed and formed separately, which is low in cost. As an alternative, the insert 303 is not provided, and the rotation-limiting column segment 301a and the guide column segment 301b can be directly formed as one piece.

[0038] Specifically, such as Figure 2 As shown, the wrench includes a first magnetic member 40, which is assembled with the first handle 20. When the first handle 20 and the second handle 30 are connected, the first handle 20 and the second handle 30 are attracted to each other via the first magnetic member 40. Alternatively, the first magnetic member 40 can be assembled with the second handle 30, or the first handle 20 and the second handle 30 can each be assembled with a first magnetic member 40, and the two first magnetic members 40 can be attracted to each other.

[0039] Specifically, such as Figure 2As shown, when the first magnetic member 40 is assembled on a handle with a socket, a first groove 202 can be provided on an end wall at the end of the socket's rotation-limiting hole section 201a away from the hole opening, thereby accommodating the first magnetic member 40 in the first groove 202. When the first magnetic member 40 is assembled on a handle with a post, a first groove 202 can be provided on the end surface of the post's rotation-limiting column section 301a away from the hole opening, thereby accommodating the first magnetic member 40 in the first groove 202. This ensures that one end surface of the first magnetic member 40 is unobstructed, thereby better enabling the magnetic attraction to function.

[0040] like Figure 4 As shown, the actuator provided by this application includes the above-mentioned wrench and an actuator shaft. The wrench body 10 is sleeved on the outside of the actuator shaft. When the wrench is swung, it can drive the actuator shaft to rotate to operate valves, baffles and other equipment.

[0041] Specifically, the wrench body 10 is connected to the actuator shaft via a screw. The rotation-limiting column section 301a of the second handle 30 is adapted to engage with the screw. This means that the screw can be unscrewed using the second handle 30. Once the screw is unscrewed, the wrench body 10 and the first handle 20 can be removed axially along the actuator shaft. Specifically, if the screw is a hexagon socket head screw, the cross-sectional outer contour of the rotation-limiting column section 301a is a regular hexagon.

[0042] Specifically, such as Figure 4 As shown, the actuator further includes a housing 60. One end of the actuator shaft extends outside the housing 60, and the wrench body 10 is sleeved outside the actuator shaft end. The housing 60 is provided with a third connecting portion 601, which is removably connectable to the second connecting portion 301 of the second handle 30, thereby enabling the housing 60 and the second handle 30 to be removably connected.

[0043] When the wrench needs to be swung for operation, the second handle 30 is connected to the first handle 20. When the wrench needs to be swung for operation, the second handle 30 can be detached from the first handle 20 and connected to the housing 60 for storage. This avoids the problem of the second handle 30 being connected to the first handle 20, resulting in a long total handle length and extending beyond the side of the housing 60, which would take up a lot of space in the actuator and be inconvenient to use and transport.

[0044] Specifically, the detachable connection method between the third connection part 601 and the second connection part 301 includes but is not limited to plug-in connection, snap-on connection, threaded connection, etc.

[0045] In the illustrated embodiment, the second connection portion 301 is a plug, and the third connection portion 601 is substantially similar in structure to the first connection portion 201, being a socket that can be adapted to the plug. This allows the second handle 30 and the housing 60 to be connected and disconnected simply by plugging and unplugging, making operation more convenient.

[0046] Specifically, such as Figure 5 As shown, the actuator includes a second magnetic member 50, and the housing 60 is assembled with the second magnetic member 50. When the second handle 30 and the housing 60 are connected, the second handle 30 and the housing 60 are attracted to each other through the second magnetic member 50. In the illustrated embodiment, an end wall is provided at the end of the socket of the housing 60 away from the hole, and a second groove 604 is provided on the end wall, and the second magnetic member 50 is accommodated in the second groove 604. Alternatively, the second magnetic member 50 can also be assembled to the second handle 30, or a second magnetic member 50 can be assembled to each of the second handle 30 and the housing 60, and the two second magnetic members 50 can be attracted to each other. Alternatively, a magnetic member can be assembled on the second handle 30, and the magnetic member can be attracted to the housing 60 as the first magnetic member 40, and can also be attracted to the first handle 20 as the second magnetic member 50.

[0047] like Figure 4 As shown, the housing 60 is provided with a recessed portion 602, which surrounds the outer side of the actuator shaft. The wrench body 10 is at least partially located within the recessed portion 602. The inner surface of the recessed portion 602 is contoured to the outer surface of the wrench body 10. This improves the integrity of the actuator. Specifically, a side opening 602a is provided on one side of the recessed portion 602, through which the first handle 20 extends. This allows for direct manipulation of the first handle 20 for small swings of the wrench.

[0048] like Figure 4 As shown, the housing 60 has a notch 603 located on one side of the side opening 602a of the recessed portion 602 and on one side of the third connecting portion 601. When the second connecting portion 301 of the second handle 30 is connected to the third connecting portion 601 of the housing 60, the second handle 30 is accommodated in the notch 603. Thus, using the notch 603 to accommodate the second handle 30 further helps reduce the footprint of the actuator.

[0049] like Figure 4 As shown, when the second handle is connected to the housing 60, the second handle 30 is located below the first handle 20 and there is a gap between the first handle 20. In this way, the integration is higher and the footprint is smaller. Moreover, when the second handle 30 is connected to the housing 60, the swing of the first handle 20 is not affected.

[0050] In summary, the core idea of ​​the present application is to fix the first handle 20 on or integrally set on the wrench body 10, and to detachably connect the second handle 30 to the first handle 20. When the wrench is in use, the second handle 30 can be connected to the first handle 20 to save effort in operation. When the wrench is not in use, the second handle 30 can be removed and stored separately, avoiding the problem that the second handle 30 is always connected to the first handle 20, resulting in a longer total length of the handle and a large space occupied.

[0051] The principles and implementation methods of the present application have been described above using specific examples. The description of the above embodiments is only intended to help understand the method and core concept of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, various improvements and modifications may be made to the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.
