[0047] See also Figure 1-6 In this embodiment, the disassembly device includes: a hollow cylinder 1, an embedded hexagon 2, a handheld component, an extension component and a fixing component.

[0048] In this embodiment, one end of the hollow cylinder 1 is an open end and the other end is a sealed end; the embedded hexagon 2 is provided at the sealed end and is fixedly connected to the hollow cylinder 1 for disassembling parts.

[0049] In this embodiment, the inner diameter of the embedded hexagon 2 is the same as the size of the screw on the evaporator liquid level sensor.

[0050] The handheld component is arranged just above the opening end for handholding.

[0051] In this embodiment, the user rotates the handheld assembly to rotate the embedded hexagon 2, thereby achieving installation and removal.

[0052] The extension component is arranged between the handheld component and the hollow cylinder 1 and is used to extend the distance between the handheld component and the hollow cylinder 1 .

[0053] In this embodiment, the space occupied by the entire device can be reduced by extending the components, and the length can be extended when necessary.

[0054] The fixing component is connected to the extension component and is used to fix the hollow cylinder 1 and the extension component together.

[0055] In this embodiment, the extension component can be removed through the fixing component to change the vertical height, and part of the handheld component can be inserted into the hollow cylinder 1 to extend the horizontal length, so as to adapt to different spaces for disassembly and installation.

[0056] like Figure 2 and Figure 6As shown, the fixing assembly includes: a worm wheel 7, a worm 8, a turntable 9, four groups of vertical rods 10, four groups of fixing parts 11, four groups of limiting rods 12, and four groups of limiting parts 13.

[0057] The worm wheel 7 is arranged inside the hollow cylinder 1 ; the worm 8 passes through the corresponding position of the hollow cylinder 1 and is rotationally connected to the hollow cylinder 1 .

[0058] In this embodiment, the worm gear 7 can be driven to rotate slowly by rotating the worm 8 .

[0059] The turntable 9 is coaxially arranged with the worm gear 7; four sets of slide grooves are provided on the upper end surface of the turntable 9; a limiting groove is provided on the edge of the turntable 9; one end of each set of vertical rods 10 is provided in the slide groove and is slidably connected to the turntable 9 through the slide groove.

[0060] In this embodiment, the worm gear 7 drives the turntable 9 to rotate synchronously. The turntable 9 slides between the sliding grooves and the vertical rods 10, so that the four groups of vertical rods 10 can move toward the middle or toward the outside at the same time.

[0061] Each set of fixing members 11 is arranged at the other end of the vertical rod 10 and is fixedly connected to the vertical rod 10; one end of each set of limiting rods 12 extends to the inside of the fixing member 11 and is slidably connected to the fixing member 11; the other end is fixedly connected to the inner wall of the hollow cylinder 1.

[0062] In this embodiment, the group limiting rod 12 can limit the fixing member 11 to move only horizontally.

[0063] One end of each set of limiting members 13 is disposed in the limiting groove and is slidably connected to the turntable 9 through the limiting groove; the other end is fixedly connected to the inner wall of the hollow cylinder 1 .

[0064] In this embodiment, when the turntable 9 rotates, the limiting groove will slide along the outer wall of the limiting member 13 .

[0065] One end of the worm 8 is provided with a knob, and the other end is provided with a cross pattern.

[0066] In this embodiment, the knob and the worm 8 can be disassembled. When the knob is damaged, the worm 8 can be rotated by inserting a screwdriver into the cross groove.

[0067] When the overall shape needs to be changed, the worm 8 is rotated by turning the knob, and the worm 8 drives the worm wheel 7 to rotate; the worm wheel 7 also drives the turntable 9 to rotate, and the turntable 9 rotates under the restriction of the limit member 13, and through the sliding between the slide groove and the vertical rod 10, the four groups of vertical rods 10 can be moved outward at the same time; the vertical rod 10 drives the fixing member 11 to move; the fixing member 11 moves under the restriction of the limit rod 12. After the fixing member 11 is disengaged from the notch of the connecting member 14, the extension component is disassembled to change the vertical height, and part of the handheld component is inserted into the hollow cylinder 1 to extend the horizontal length, so that the same disassembly device can be used for installation and disassembly in spaces of different sizes, and there is no need to frequently change tools, which is easy to use.

[0068] like Figure 3 and Figure 4 As shown, the extension assembly includes: a connecting member 14, a solid cylinder 15, an annular groove 16, a slider 17 and a rotating part 3.

[0069] A notch is provided on the surface of the connecting member 14 at a position corresponding to the fixing member 11 , so that the fixing member 11 can be inserted into the connecting member 14 .

[0070] In this embodiment, the connecting member 14 is fixed by inserting the fixing member 11 into the notch of the connecting member 14 .

[0071] The solid cylinder 15 is disposed above the connecting member 14 and is fixedly connected to the connecting member 14 ; the annular groove 16 is formed on the surface of the solid cylinder 15 .

[0072] In this embodiment, the annular groove 16 is inclined, and the angle formed by it and the horizontal plane is 60 degrees.

[0073] The slider 17 is disposed in the annular groove 16 and is slidably connected to the solid cylinder 15 through the annular groove 16 .

[0074] In this embodiment, the slider 17 can slide along the annular groove 16 and change its height.

[0075] The rotating portion 3 is sleeved on the outer wall of the solid cylinder 15 and fixedly connected to the slider 17 .

[0076] In this embodiment, the sliding block 17 is driven to rotate synchronously by rotating the rotating portion 3 , and the sliding block 17 slides along the annular groove 16 and changes its height.

[0077] The angle between the annular groove 16 and the vertical center axis of the solid cylinder 15 is 30 degrees.

[0078] When extension is required, the user rotates the rotating part 3, and the rotating part 3 drives the slider 17 to rotate synchronously. The slider 17 slides upward along the annular groove 16 and increases in height, thereby achieving the purpose of extension.

[0079] The extension assembly further includes: a limiting assembly; the limiting assembly is connected to the solid cylinder 15 and is used to limit the position of the rotating part 3.

[0080] like Figure 3 and Figure 4 As shown, the limiting assembly includes two groups of limiting slots 18 and a limiting portion 19 .

[0081] Specifically, two groups of limiting slots 18 are opened on the surface of the solid cylinder 15; the limiting part 19 is composed of an arc plate and a cross bar, one end of the cross bar is fixedly connected to the inner wall of the arc plate; the other end of the cross bar passes through the corresponding position of the rotating part 3 and extends to a group of limiting slots 18.

[0082] In this embodiment, when the rotating portion 3 is at the lowest end and the highest end, the limiting portion 19 corresponds to the limiting slot 18 .

[0083] The two groups of limiting slots 18 are symmetrically arranged along the vertical center axis of the solid cylinder 15 with respect to the highest end and the lowest end of the annular groove 16 .

[0084] like Figure 1 As shown, the handheld assembly includes: a connecting portion 4, a second connecting hole 21, a clamping portion 5 and a handheld portion 6.

[0085] The connecting portion 4 is disposed at the top of the rotating portion 3 and fixedly connected to the rotating portion 3 ; the second connecting hole 21 is opened on the connecting portion 4 ; the clamping portion 5 passes through the second connecting hole 21 and is slidably connected to the second connecting hole 21 .

[0086] In this embodiment, the clamping portion 5 is rotated to drive the rotating portion 3 to rotate via the connecting portion 4; and when the clamping portion 5 is pulled outward, the clamping portion 5 will be removed.

[0087] The hand-held portion 6 is disposed at one end of the clamping portion 5 and is rotatably connected to the clamping portion 5 .

[0088] In this embodiment, the clamping portion 5 is driven to rotate by horizontally rotating the hand-held portion 6 ; and when the hand-held portion 6 is vertically rotated, the horizontal length of the clamping portion 5 can be increased.

[0089] like Figure 1 and Figure 5 As shown, the disassembly device further includes: two groups of first connecting holes 20; the two groups of first connecting holes 20 are both opened on the surface of the hollow cylinder 1, and the inner diameter of the first connecting holes 20 is the same as the inner diameter of the second connecting holes 21.

[0090] In this embodiment, the disassembled clamping portion 5 can be inserted into the first connecting hole 20 to perform horizontal rotation.

[0091] Working principle:

[0092] When the disassembly device is in use and the vertical space is relatively large, the limiting portion 19 is pulled outward so that the limiting portion 19 disengages from the limiting slot 18. At this time, the user rotates the rotating portion 3, and the rotating portion 3 drives the slider 17 to rotate synchronously. The slider 17 will slide upward along the annular groove 16 and increase its height, thereby achieving the purpose of extension.

[0093] Subsequently, the screws on the evaporator liquid level sensor are wrapped by the embedded hexagon 2, and the handheld component is rotated. The handheld component drives the hollow cylinder 1 and the embedded hexagon 2 to rotate through the extension component and the fixing component, thereby installing and removing the screws.

[0094] When the horizontal space is larger, the worm 8 is rotated by turning the knob, and the worm 8 drives the worm wheel 7 to rotate; the worm wheel 7 drives the turntable 9 to rotate at the same time, and the turntable 9 rotates under the restriction of the limit member 13, and the four sets of vertical rods 10 can be moved outward at the same time by sliding between the slide groove and the vertical rod 10; the vertical rod 10 drives the fixing member 11 to move; the fixing member 11 moves under the restriction of the limit rod 12, and after the fixing member 11 is disengaged from the notch of the connecting member 14, the extension component is disassembled to change the vertical height, and part of the handheld component is inserted into the hollow cylinder 1 to extend the horizontal length, so that the same disassembly device can be used for installation and disassembly in spaces of different sizes, and there is no need to frequently change tools, which is easy to use and completes the use of this device.

[0095] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
