[0025] The application embodiment provides a combination fastener dismounting tool in a narrow space, solves the problem of inconvenient combination fastener dismounting in a narrow space, and realizes fast and stable dismounting of nuts, elastic pads, flat pads and the like.

[0026] To solve the above technical problems, the technical solution in the application embodiment has the following general idea:

[0027] The combination fastener is widely used in the electronic and electrical industry, the mechanical manufacturing industry, the construction industry and the furniture industry. In the electronic and electrical industry, the combination fastener is widely used in the assembly of computers, mobile phones and household appliances, such as the fixation of mobile phone shells and the installation of parts on computer motherboards. The combination fastener can ensure the firmness and stability of the connection and meet the requirements of thin and small electronic products.

[0028] At present, when installing and dismounting nuts, elastic pads, flat pads and the like in a narrow space such as a groove, it is generally relied on the hands of an operator to preinstall or finally take out. The operator faces the problem of limited space, and the hands cannot fully enter the inside, such as the groove, resulting in unstable gripping and inconvenient dismounting. The combination fastener of nuts, elastic pads and flat pads is difficult to be dismounted as a whole, and the tool needs to be replaced, resulting in low dismounting efficiency. During the dismounting process of nuts, elastic pads and flat pads, the phenomenon of part falling is prone to occur. Therefore, it is urgent to propose a dismounting tool for a narrow space to dismount nuts, elastic pads, flat pads and the like.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail in combination with the drawings of the specification and specific embodiments.

[0030] First, a combination fastener dismounting tool in a narrow space provided by the application embodiment will be introduced.

[0031] The application provides a tool for assembling and disassembling a combined fastener in a narrow space Figures 1-4 The tool comprises a wrench assembly 1, a baffle assembly and a sub-baffle assembly; the wrench assembly 1 comprises a handle 11 extending along a first direction X1, and a first head 12 fixedly connected to a first end of the handle 11, wherein the first head 12 is provided with a first clamping cavity A with one side open to be sleeved with the combined fastener.

[0032] Specifically, the baffle assembly is stacked on a first side of the wrench assembly 1 and fixedly connected with the first head 12, and the baffle assembly comprises two baffles 2 symmetrical along a second direction X2 and consistent in structure, wherein the distal ends of the baffles 2 are spaced from the first head 12 along a third direction X3 and correspond to part of the width of the first clamping cavity A along the third direction X3.

[0033] The sub-baffle assembly is stacked on a second side of the wrench assembly 1, and the sub-baffle assembly comprises a baffle 3 movable along the first direction X1, wherein the baffle 3 is provided with a second clamping cavity B consistent in shape with the first clamping cavity A, and the distal ends of the baffles 2 and the baffle 3 in a preset target position partially overlap with each other in two projections in any two-dimensional plane perpendicular to the third direction X3.

[0034] In the application, the wrench assembly 1 is provided with the baffle assembly and the sub-baffle assembly on two sides respectively, the first head 12 of the wrench assembly 1 is provided with the first clamping cavity A with one side open to be sleeved with the combined fastener, the two baffles 2 of the baffle assembly are fixed to the first head 12, the distal ends of the baffles 2 correspond to part of the width of the first clamping cavity A along the third direction X3, and in the case that the combined fastener is sleeved in the first clamping cavity A, the combined fastener is limited by the two baffles 2 on one side.

[0035] In the case that the first head 12 is in a narrow space, the baffle 3 in the sub-baffle assembly is pushed to move to a position corresponding to the first head 12, and an operator can apply an external force to extrude the baffle 3 to deform the baffle 3 and extrude the other side of the combined fastener, so as to realize clamping and fixing of the combined fastener to be assembled and disassembled; the application effectively solves the problem of assembling and disassembling the combined fastener in a narrow space, the tool is small and portable, and the tool does not need to be replaced in the middle, thereby preventing the risk of dropping and improving work efficiency.

[0036] In some embodiments, please refer to Figures 1-4 The first head 12 and the baffle 3 are both provided with two outer side walls opposite along the second direction X2 and extending linearly along the first direction X1.

[0037] In the embodiments of the present application, it can be understood that the outer side of the head of a conventional wrench tool usually has a certain curvature, and when the tool is used in a narrow space, the tool is interfered by the limited space. In the present application, the outer side walls of the first head 12 and the blocking piece 3 are processed and cut to be linear to avoid interference during movement and facilitate the tool to enter the narrow space.

[0038] In some embodiments, referring to Figure 2 and Figure 3 , the blocking plate 2 comprises a first branch plate 21 and a second branch plate 22 connected in a staggered manner, and the distal end of the blocking plate 2 is the second branch plate 22. The first branch plate 21 and the second branch plate 22 extend along the third direction X3 and the second direction X2, respectively.

[0039] In the embodiments of the present application, it can be understood that the extension size of the first branch plate 21 along the third direction X3 determines the distance of the second branch plate 22 from the first clamping cavity A. One side of the combined fastener can protrude out of the first clamping cavity A and be limited and constrained by the two second branch plates 22.

[0040] In one example, the wrench assembly 1 further comprises a second head 13 connected to the second end of the handle 11; and the first clamping cavity A provides an inner wall surface corresponding to and matching the outer peripheral surface of the combined fastener.

[0041] In some embodiments, referring to Figures 1-4 , the auxiliary blocking piece assembly further comprises a housing 4 fixed to the handle 11 and extending along the first direction X1. The auxiliary blocking piece assembly further comprises a strip-shaped connecting plate 5 slidably telescoped in the housing 4 along the first direction X1, and one end of the connecting plate 5 is fixedly connected to the blocking piece 3.

[0042] In the embodiments of the present application, it can be understood that the blocking piece 3 is slidably connected to the housing 4 through the connecting plate 5. When the combined fastener is assembled or disassembled in a narrow space, in order to laterally constrain the combined fastener by the blocking piece 3, an external force can be applied to move the blocking piece 3.

[0043] In some embodiments, referring to Figures 1-4 , the auxiliary blocking piece assembly further comprises a sliding block 6, and a strip-shaped notch is formed in the side of the housing 4 away from the handle 11. Part of the sliding block 6 extends into the housing 4 through the strip-shaped notch and is fixedly connected to the connecting plate 5. The sliding block 6 is slidably connected to the housing 4, and the blocking piece 3 is spaced apart from the wrench assembly 1 along the third direction X3. The blocking piece 3 can be driven by the sliding block 6 to move to a preset target position.

[0044] In the embodiments of the present application, it can be understood that after the push block 6 moves the baffle 3 to the preset target position, the baffle 3 is located outside the combined fastener, and in order to clamp the combined fastener, an external force can be applied to extrude the baffle 3 to make the baffle 3 deform to cooperate with the second supporting plate 22, thereby clamping the combined fastener for dismounting operation. It should be noted that the baffle 3 has a certain toughness, and the baffle 3 can restore to the original state after being bent under stress.

[0045] In summary, compared with the prior art, the present application has the following beneficial effects:

[0046] 1. The first head 12 and the baffle 3 of the present application both have two outer side walls that are opposite in the second direction X2 and extend linearly in the first direction X1; by machining and cutting the outer side walls of the first head 12 and the baffle 3 to be linear, interference during movement is avoided, and tools can easily enter narrow spaces.

[0047] 2. In the case where the first head 12 is in a narrow space, the baffle 3 in the secondary baffle assembly can be moved to a position corresponding to the first head 12, and an operator can apply an external force to extrude the baffle 3 to make the baffle 3 deform and extrude the other side of the combined fastener, thereby achieving clamping and fixing of the combined fastener for dismounting; the present application effectively solves the problem of installing and dismounting the combined fastener in a narrow space, and the dismounting tool is small and portable, without the need to change tools during the process, preventing the risk of dropping the piece and improving work efficiency.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
