Referring to fig. 1 to 4, fig. 1 is a schematic view of a variable axis socket wrench 100 according to an embodiment of the present disclosure; fig. 2 is a schematic view of a socket head 110 of a variable axis socket wrench 100 according to an embodiment of the present disclosure; FIG. 3 is a schematic view of a first member 121 of the booster bar 120 according to an embodiment of the present disclosure; fig. 4 is a schematic view of the second part 122 of the forcing rod 120 provided in the embodiment of the present application.

In the present embodiment, the variable axis socket wrench 100 may include: a sleeve head 110 and a force bar 120.

Illustratively, the sleeve head 110 may include opposite head and tail portions, the head portion having a nut groove 111, and the head portion having a sleeve 112 and the tail portion having a slider 113.

The slider 113 is inserted into the slide rail 1211 and can reciprocate in the direction of the slide rail 1211 to change the relative positional relationship between the axis of the force application rod 120 and the axis of the sleeve head 110.

This allows the extension 114 of the sleeve head 110 to be inserted into the bowl when the bowl housing is removed, and the head is rotated so that the nut recess 111 is aligned with the nut of the bowl (typically a hex nut, so that the nut recess 111 is a correspondingly sized hex recess). Then, the position of the slider 113 in the slide rail 1211 is adjusted according to the relative position of the force applying rod 120 and the guide tube, so that the force applying rod 120 does not collide with the guide tube. Force is applied to the handle of the stress application rod 120, so that torque is generated to drive the filter bowl shell to rotate, and disassembly and assembly are realized. Therefore, when the nut is applied with torque to realize disassembly, the guide pipe and the machine part are effectively avoided, the sufficient operation space is ensured, the nut is prevented from being screwed to slide and round, and the disassembly and assembly task is completed efficiently. This allows the force application rod 120 axis to be slightly offset from the sleeve head 110 axis to avoid pitting or damage from impact with the catheter.

In this embodiment, a portion of the slide 1211 is channel-shaped, and another portion of the slide 1211 is groove-shaped (as shown in fig. 1 and 2, it can be understood as a slide 1211 with a notch). The slider 113 is inserted into the slide 1211 and can reciprocate within the range of the groove-shaped slide 1211. Thus, a part of the slider 113 can be inserted into the channel-shaped slide rail 1211 to prevent the slider 113 from coming off, thereby facilitating the operation.

In this embodiment, the force applying rod 120 includes a first member 121 and a second member 122, the first member 121 has a first end and a second end opposite to each other, the first end is provided with a slide rail 1211, and the second end is provided with a cross-shaped groove 1212; the second member 122 has a third end and a fourth end opposite to each other, the third end is provided with a cross spline 1221, the fourth end is provided with a handle 1222, wherein the cross spline 1221 is inserted into the cross groove 1212 to connect the first member 121 and the second member 122, and the first member 121 and the second member 122 are kept relatively fixed in the axial rotation direction. In this way, the length of the force application rod 120 can be adjusted, and the angle of the handle 1222 on the force application rod 120 can be adjusted, so that various assembling and disassembling environments can be adapted.

In this embodiment, a small hole is formed in the first member 121 every other predetermined length, a small hole is formed in the second member 122 every other predetermined length, the cross spline 1221 is inserted into the cross spline 1212, some or all of the small holes in the first member 121 correspond to some or all of the small holes in the second member 122 one to one, and a pin having a diameter equal to that of the small hole is simultaneously inserted into the small hole in the first member 121 and the corresponding small hole in the second member 122, so that the first member 121 and the second member 122 are connected. This fixes the length of the force lever 120 and the angle of the handle 1222 in use, which provides more secure attachment stability of the force lever 120 of the variable axis socket wrench 100.

In the present embodiment, the small holes formed in the first member 121 and the second member 122 satisfy the condition: and small holes with the diameter of 3 mm are arranged every 90 degrees and every 5 cm. In this manner, the angle of the handle 1222 is adjustable, and a small hole with a diameter of 3 mm is formed every 5 cm, which is well considered for the size of the force application rod 120 of the variable axis socket wrench 100, and in other possible implementations, other hole forming parameters can be adopted to adapt to the size of the force application rod 120, which is not limited herein.

In this embodiment, the sleeve 112 of the sleeve head 110 is also provided with an extension cartridge 114 that matches the outside diameter of the bowl housing. An extension cylinder 114 having an inner diameter substantially the same as the inner diameter of the bowl housing is provided on the sleeve 112 to restrict the angle at which the nut groove 111 is inserted into the nut of the bowl housing, thereby further preventing the nut from being damaged by slipping.

Referring to fig. 5, fig. 5 is a schematic view of a socket wrench 100 with variable axis for disassembling a hexagon nut of a filter bowl housing according to an embodiment of the present invention. First, the extension cartridge 114 of the variable axis socket wrench 100 can be aligned with the bowl housing and the extension cartridge 114 can be placed over the bowl housing such that the hex nut on the bowl housing fits into the nut groove 111 of the sleeve head 110. The axial position of the force application rod 120 can be adjusted by adjusting the position of the sliding block 113, so as to avoid the collision between the force application rod 120 and the components such as the guide pipe. Force is applied to the handle of the force applying rod 120, so that torque is generated to drive the filter bowl shell to rotate, and disassembly and assembly are achieved.

In other possible implementations, other force applying rods 120 can be sleeved on the handle 1222 to obtain a larger moment, which is not limited herein.

In summary, the present embodiment provides a variable axis socket wrench 100, in which a socket head 110 of the variable axis socket wrench 100 includes a head portion and a tail portion, the head portion has a nut groove 111, and the head portion is externally provided with a socket 112, and the tail portion is provided with a sliding block 113.

The slider 113 is inserted into the slide rail 1211 and can reciprocate in the direction of the slide rail 1211 to change the relative positional relationship between the axis of the force application rod 120 and the axis of the sleeve head 110. This allows the extension 114 of the sleeve head 110 to be inserted into the bowl when the bowl housing is removed, and the head is rotated so that the nut recess 111 is aligned with the nut of the bowl (typically a hex nut, so that the nut recess 111 is a correspondingly sized hex recess). Then, the position of the slider 113 in the slide rail 1211 is adjusted according to the relative position of the force applying rod 120 and the guide tube, so that the force applying rod 120 does not collide with the guide tube. Force is applied to the handle of the stress application rod 120, so that torque is generated to drive the filter bowl shell to rotate, and disassembly and assembly are realized. Therefore, when the nut is applied with torque to realize disassembly, the guide pipe and the machine part are effectively avoided, the sufficient operation space is ensured, the nut is prevented from being screwed to slide and round, and the disassembly and assembly task is completed efficiently. This allows the force application rod 120 axis to be slightly offset from the sleeve head 110 axis to avoid pitting or damage from impact with the catheter.
