[0022] Please see Figure 1 The present application provides an adjustable wrench, comprising: a fixed part 1, a movable part 4, and a multi-functional socket 5. The fixed part 1 is provided with an outwardly protruding protrusion 101; the multi-functional socket 5 is detachably mounted on the mounting part 401; the movable part 4 is provided with the mounting part 401; the movable part 4 is adjustable in position and mounted on the fixed part 1.
[0023] In this embodiment, the multi-functional sleeve 5 is aligned with the protrusion 101. When the movable part 4 is adjusted, the multi-functional sleeve 5 can move in a straight line to move closer to or further away from the protrusion 101. The movable part 4 and the fixed part 1 form a wrench structure. The method of adjusting their relative positions can follow the structure of existing wrenches, for example, a lead screw is provided on the fixed part 1; a rotatable threaded sleeve 8 is provided on the movable part 4; the threaded sleeve 8 is engaged with the lead screw; when the threaded sleeve 8 rotates, the movable part 4 moves along the lead screw to achieve position adjustment.
[0024] Specifically, when the movable part 4 is adjusted, it can move the multi-functional sleeve 5 closer to the contact protrusion 101 or move the multi-functional sleeve 5 away from the protrusion 101. Correspondingly, when the multi-functional sleeve 5 abuts against the protrusion 101, the end face of the multi-functional sleeve 5 can form a wrench clamping structure with the protrusion 101 to clamp the workpiece.
[0025] In this implementation, please refer to Figures 1 to 4 The multi-functional sleeve 5 has at least a first end face 501, a second end face 502, a third end face 503 and a fourth end face 504; the first end face 501 has an angular notch; the second end face 502 has an arc-shaped groove surface; the third end face 503 has a blade structure; the fourth end face 504 has a planar structure; the multi-functional sleeve 5 can adjust its end face facing the protrusion 101.
[0026] The multi-functional sleeve 5 can be adjusted in the way that its end face facing the protrusion 101 can be adjusted. For example, the multi-functional sleeve 5 can be disassembled, and after the operator disassembles it, it can be reinstalled after adjusting its end face facing the protrusion 101.
[0027] The first end face 501 has an angular notch that allows bolts and other structures to be inserted, enabling better bolt or nut fixing. The second end face 502 has an arc-shaped groove that can fit into tubular objects, facilitating their fixing with the protrusion 101. The blade structure of the third end face 503 can be used to cut the outer sheath of wires; the planar structure of the fourth end face 504 is suitable for clamping planar objects.
[0028] Specifically, the end face of the protrusion 101 facing the multi-functional sleeve 5 may be provided with a notch 2; the notch 2 is also angular, which can cooperate with the first end face 501 to better fix the bolt structure.
[0029] In some work scenarios involving the fixing of tubular objects, such as when dealing with cable conduits passing through walls, it is necessary to fix the conduits. In this case, the worker can adjust the multi-functional sleeve 5 so that the second end face 502 faces the protrusion 101, and use its arc-shaped groove surface to fit tightly with the protrusion 101, thereby better fixing the conduit.
[0030] In scenarios requiring the cutting of wire insulation, the operator can adjust the multi-functional socket 5 so that the third end face 503 faces the protrusion 101, utilizing the blade structure for quick and precise cutting, thus improving work efficiency. For clamping flat objects, the fourth end face 504 is selected to ensure the object is stable and does not slip. When using the third end face 503, the operator can adjust the position of the movable part 4 to lightly clamp the wire, hold the wire with one hand, and turn the wrench with the other hand to drive the blade structure to cut around the wire.
[0031] In one embodiment, the end face of the protrusion 101 facing the multi-functional sleeve 5 may have a second notch 3; a locking member capable of engaging the second notch 3 may be provided on one end face of the multi-functional sleeve 5, such as the first end face 501. When the first end face 501 abuts against the protrusion 101, the locking member engages in the second notch 3 and fits with the second notch 3, enabling the compression of an object placed inside the second notch 3. In practical applications, the object placed inside the second notch 3 may be, for example, a metal sheet or a flexible tube that needs to be flattened.
[0032] In one embodiment, a fixed shaft 6 is provided on the mounting part 401; the multi-functional sleeve 5 is rotatably sleeved on the fixed shaft 6.
[0033] In this embodiment, the multi-functional sleeve 5 can be adjusted by rotation to face the protrusion 101. In practical applications, the fixed shaft 6 can be a polygonal column, and its outer periphery is made of flexible material to form a protrusion, so that the multi-functional sleeve 5 can be locked with the flexible corner area during rotation to assist in the positioning of the multi-functional sleeve 5 after rotation.
[0034] In one embodiment, the mounting portion 401 is provided with an elastic protrusion 7; the multifunctional sleeve 5 is provided with a plurality of grooves 505 on the end face near the mounting portion 401; the plurality of grooves 505 are evenly distributed in a circumference; the grooves 505 are engaged with the elastic protrusion 7.
[0035] Specifically, when the multi-functional sleeve 5 rotates to align any end face with the protrusion 101, the elastic protrusion 7 and the groove 505 cooperate to lock and fix the multi-functional sleeve 5 in place, preventing the multi-functional sleeve 5 from rotating during operation.
[0036] In one implementation, the elastic protrusions 7 can be two or four. Taking four as an example, the four elastic protrusions 7 are evenly distributed around the outer periphery of the fixed shaft 6. Correspondingly, the multi-functional sleeve 5 includes four end faces, and the multi-functional sleeve 5 is provided with four grooves 505, which correspond to the four elastic protrusions 7 respectively, so that every time the multi-functional sleeve 5 rotates 90°, the grooves 505 will engage with the elastic protrusions 7.
[0037] In one embodiment, the elastic protrusion 7 includes a spring and a ball; a mounting groove 402 is provided on the mounting part 401; the spring is disposed in the mounting groove 402; the ball is connected to the outside of the spring and extends out of the mounting groove 402.
[0038] As one implementation method, the grooved surface is provided with friction texture to increase its friction.
[0039] In one embodiment, the movable part 4 is provided with a first component groove 403; a flathead screwdriver 9 is detachably mounted on the first component groove 403.
[0040] Furthermore, a second component slot 404 is provided on the movable part 4; a Phillips screwdriver 10 is detachably provided in the second component slot 404.
[0041] The flathead screwdriver 9 and the Phillips head screwdriver 10 can be used to remove and install screws. The flathead screwdriver 9 and / or the Phillips head screwdriver 10 can be equipped with a magnet 11; the magnet 11 can attract parts in scenarios where magnetic attraction is required.
[0042] In application, a second elastic protrusion 12 may be provided in the first component groove 403 or the second component groove 404. The second elastic protrusion 12 can be used to fix the flathead screwdriver 9 and the Phillips screwdriver 10, ensuring that the tools are not easily dislodged during use.
[0043] In one embodiment, both the first component slot 403 and the second component slot 404 are open toward the end face of the movable part 4, so that the flathead screwdriver 9 and the Phillips screwdriver 10 can be placed flatly into the first component slot 403 and the second component slot 404 respectively; the flathead screwdriver 9 is provided with a first irregular structure 901; the Phillips screwdriver 10 is provided with a second irregular structure 1001; the first irregular structure 901 is used to restrict the flathead screwdriver 9 from being placed flatly into the second component slot 404; the second irregular structure 1001 is used to restrict the Phillips screwdriver 10 from being placed flatly into the first component slot 403.
[0044] In practical applications, the first irregular structure 901 and the second irregular structure 1001 can be any structure, specifically such that the first irregular structure 901 can be placed flat into the first component slot 403, and the second irregular structure 1001 can be placed flat into the second component slot 404. However, when the flathead screwdriver 9 and the Phillips screwdriver 10 are swapped, the first irregular structure 901 cannot be placed flat into the second component slot 404, and the second irregular structure 1001 cannot be placed flat into the first component slot 403.
[0045] The first irregular structure 901 and the second irregular structure 1001 enable workers to correctly place the flathead screwdriver 9 and the Phillips screwdriver 10; in situations where it is inconvenient to see the wrench and the screwdriver needs to be removed, workers can remove the required screwdriver in the correct position, effectively avoiding tool misuse.
[0046] Furthermore, the fixing part 1 is provided with a snap-in groove 13; the snap-in groove 13 is used for snapping in a flathead screwdriver 9 or a Phillips screwdriver 10.
[0047] Furthermore, the fixed part 1 or the movable part 4 is provided with a scale.
[0048] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
