Detailed Description of the Preferred Embodiments

[0025] The following further describes the present invention in detail with reference to the drawings.

[0026] A screw disassembly and installation device for narrow spaces, as Figure 1 shown, includes:

[0027] A connecting sleeve 1 arranged in a hollow manner;

[0028] The handle 2, the handle 2 is coaxially arranged with the connecting sleeve 1, the handle 2 is sleeved with a first spring 21, one end of the handle 2 is a rotating end, under the action of the first spring 21, the other end of the handle 2 extends out of the connecting sleeve 1, and a first sleeve 22 is detachably installed at this end of the handle 2; and

[0029] A bracket 3 fixed to the end of the connecting sleeve 1, the bracket 3 is detachably installed with a second sleeve 31 relative to the first sleeve 22;

[0030] Wherein, the bracket 3 is further installed with an adjusting component 4, and the adjusting component 4 is used to change the distance between the second sleeve 31 and the first sleeve 22.

[0031] According to a specific embodiment provided by the present invention, the connecting sleeve 1 is a "T"-shaped tube structure, the connecting sleeve 1 is a long cylindrical structure, the end of the connecting sleeve 1 close to the rotating end of the handle 2 is a large end, and a rotating rod 23 is fixed to one end of the rotating end of the handle 2, so that the handle 2 as a whole is in a "T"-shaped structure, which is convenient for rotation.

[0032] In this embodiment, by installing the adjusting component 4 on the bracket 3, and operating the adjusting component 4 to change the distance between the second sleeve 31 and the first sleeve 22, the height of the bracket 3 can be changed, so that the second sleeve 31 and the first sleeve 22 can be better clamped onto the corresponding screw and nut, so that the height of the bracket 3 can be selected according to the actual use scenario. The present invention expands the use scenario of the screw disassembly and installation device, and the long cylindrical handle 2 and connecting sleeve 1 can extend into the working position to disassemble and install screws.

[0033] During the process of installing the screw, the screw and nut are respectively fixed by the first sleeve 22 and the second sleeve 31, and the handle 2 is rotated to tighten the screw and nut. When disassembling the fixed screw, the handle 2 is pulled up to make the first sleeve 22 and the second sleeve 31 open a certain distance, and aligned with the screw and nut, and then released. Under the action of the spring, the first sleeve 22 and the second sleeve 31 are sleeved onto the screw and nut, and then the handle 2 is rotated to disassemble the fixed screw. The first sleeve 22 and the second sleeve 31 can be set to a structure with strong magnetism, so as to facilitate replacement and disassembly.

[0034] Further, the bracket 3 includes a mounting plate 32, a bottom sleeve 33 fixed to one side of the mounting plate 32, and a base plate 34. The bottom sleeve 33 is sleeved on the end of the connecting sleeve 1. The mounting plate 32 is located on one side of the first sleeve 22. The base plate 34 is fixed to the side of the mounting plate 32 away from the connecting sleeve 1. The base plate 34 is perpendicular to the connecting sleeve 1, and the base plate 34 is detachably installed with the second sleeve 31.

[0035] According to a specific embodiment provided by the present utility model, this embodiment discloses the specific structure of a bracket 3. When the handle 2 is vertically arranged, the base plate 34 of the bracket 3 is horizontally arranged, the base plate 34 is perpendicular to the handle 2, and the mounting plate 32 is obliquely arranged. In this embodiment, the mounting plate 32 and the base plate 34 are clamped at 60°. The upper part of the mounting plate 32 is fixed to the connecting sleeve 1 through the bottom sleeve 33, and the lower part of the mounting plate 32 is fixed to the base plate 34.

[0036] Further, as Figure 2 and Figure 3 shown, the adjusting assembly 4 includes a rotation-limiting gear 41, a rotation-limiting assembly 5, and a moving rack 42. The rotation-limiting gear 41 is rotatably installed on the mounting plate 32. The moving rack 42 is slidably connected to the mounting plate 32. The moving rack 42 meshes with the rotation-limiting gear 41 and can slide along the length direction of the mounting plate 32. The rotation-limiting assembly 5 is installed on the mounting plate 32 and is located on one side of the rotation-limiting gear 41. The rotation-limiting assembly 5 is used to limit the rotation of the rotation-limiting gear 41.

[0037] According to a specific embodiment provided by the present utility model, the side surface of the rotation-limiting gear 41 is located outside the side surface of the mounting plate 32. The side of the moving rack 42 facing the rotation-limiting gear 41 has teeth so as to mesh with the rotation-limiting gear 41. The mounting plate 32, the rotation-limiting gear 41, and the moving rack 42 are arranged parallel to each other. The length direction of the mounting plate 32 is located in the height and length direction of the handle 2. In this way, when the moving rack 42 moves relative to the mounting plate 32, the moving rack 42 will drive the second sleeve 31 on the base plate 34 to move away from or close to the first sleeve 22.

[0038] Further, a sliding block 43 is fixed to one side of the moving rack 42. The mounting plate 32 is provided with a sliding groove 321 along the length direction. The sliding block 43 is slidably matched with the mounting plate 32 through the sliding groove 321. The sliding block 43 is perpendicular to the side surface of the moving teeth. One side of the sliding block 43 is fixed to the moving rack 42, and the other side has a connecting head (not visible in the figure). The connecting head is clamped into the sliding groove 321, thereby realizing the sliding fit between the moving rack 42 and the mounting plate 32.

[0039] Further, as Figure 3 shown, the rotation-limiting assembly 5 includes a second spring 51, a limiting post 52, and a fixing ring 53. The fixing ring 53 is fixed on the mounting plate 32. The limiting post 52 passes through the fixing ring 53 and can move under the limitation of the fixing ring 53. One end of the limiting post 52 is an operating end. The limiting post 52 passes through the second spring 51. Under the action of the second spring 51, the end of the limiting post 52 away from the operating end can be meshed with the rotation-limiting gear 41.

[0040] According to a specific embodiment provided by the present utility model, the rotation limiting assembly 5 is used to limit the rotation of the rotation limiting gear 41. The fixed ring 53 is located on the opposite side of the sliding block 43, that is, the sliding block 43 and the fixed ring 53 are respectively located on both sides of the rotation limiting gear 41, so that the space on the mounting plate 32 can be reasonably utilized. The end of the limiting column 52 abuts against the rotation limiting gear 41 under the action of the spring and limits the rotation of the rotation limiting gear 41. When the operator manually overcomes the resistance of the second spring 51 and pulls the limiting column 52 away from the rotation limiting gear 41, the rotation limiting gear 41 can rotate at this time, and the relative position between the moving rack 42 and the mounting plate 32 can be adjusted. Further, a pulling part is fixed at the operating end of the limiting column 52, and the pulling part is a hemispherical structure, which is convenient for the operator to manually operate.

[0041] Further, the first spring 21 is disposed at the end of the connecting sleeve 1 close to the rotating end of the handle 2. The end of the first spring 21 abuts against the first limiting ring 24 fixed to the handle 2. Under the action of the first spring 21, the first limiting ring 24 abuts against the second limiting ring 25 fixed on the inner wall of the connecting sleeve 1.

[0042] According to a specific embodiment provided by the present utility model, this embodiment provides a specific installation position of the first spring 21. Under the action of the first spring 21, the end of the handle 2 drives the first sleeve 22 to approach the second sleeve 31, so that the screw is easily fixed. After the operator operates the rotating end, the first sleeve 22 of the handle 2 can be pulled away from the second sleeve 31. In this embodiment, a second limiting ring 25 is provided on the inner wall of the connecting sleeve 1, and the first limiting ring 24 abuts against the second limiting ring 25 under the action of the first spring 21. Due to the limitation of the first spring 21 and the connecting sleeve 1, the first sleeve 22 at the end of the handle 2 cannot maintain a large distance from the second sleeve 31. Therefore, the present utility model installs an adjusting assembly 4 on the mounting plate 32 for further adjustment, so as to further increase the distance between the first sleeve 22 and the second sleeve 31, and thus apply the screw dismounting and mounting device of the present utility model to screw dismounting and mounting constructions of more sizes.

[0043] Further, as Figure 1 and Figure 4As shown, a strip-shaped mounting groove 341 is formed in the base plate 34. The mounting groove is a "T"-shaped groove. The second sleeve 31 can move in the mounting groove to change the distance between the second sleeve 31 and the mounting plate 32. When the mounting plate 32 and the moving rack 42 move relative to each other, the second sleeve 31 will have a horizontal displacement relative to the first sleeve 22, making it impossible for the second sleeve 31 and the first sleeve 22 to be in the same straight line. To solve the above problem, in this embodiment, a strip-shaped mounting groove 341 is formed in the base plate 34. The second sleeve 31 can be taken out from the side of the strip-shaped mounting groove 341 away from the mounting plate 32 for replacement. The structure of the second sleeve 31 connected to the base plate 34 is a "T"-shaped structure, which just matches the shape of the strip-shaped mounting groove 341, so as to change the distance between the second sleeve 31 and the mounting plate 32, and make the second sleeve 31 and the first sleeve 22 in the same straight line.

[0044] When installing the screw of the present utility model: replace the first sleeve 22 and the second sleeve 31, then place the screw rod and the nut, and finally install the screw rod and the nut.

[0045] When disassembling: lift the handle 2 to facilitate the first sleeve 22 and the second sleeve 31 to place the screw to be disassembled. Then align the screw rod cap and the nut, and then let go. Under the action of the first spring 21, the first sleeve 22 and the second sleeve 31 are sleeved on the screw rod and the nut, and then turn the handle 2 to disassemble the screw rod.

[0046] Finally, it should be noted that: in the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0047] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
