[0002] Adjusting feet are commonly used in devices such as refrigerators and cabinets. The adjusting foot includes an adjusting caster and an adjusting stud. The adjusting caster is often set to abut against the ground, and the adjusting stud is threadedly connected to the corresponding device. By using an external tool such as a wrench to relatively rotate between the adjusting caster and the adjusting stud, the height adjustment of the device at the corresponding position can be achieved. In the prior art, when rotating the adjusting caster, it is necessary to clamp the wrench on the adjusting caster and then only rotate in one direction; when it is necessary to rotate the adjusting caster in the reverse direction, the wrench will disengage from the adjusting caster, and it is necessary to re-adjust the posture of the wrench and then clamp it on the adjusting caster again. The user operation is extremely inconvenient and needs to be optimized. Summary of the Utility Model
[0003] The main object of the utility model is to propose a wrench, aiming to improve the problem that the rotation control of the adjusting foot is relatively inconvenient.
[0004] To achieve the above object, the wrench proposed by the utility model is used to rotate a rotating body provided with a plurality of slots in the circumferential direction, and is characterized in that the wrench includes:
[0005] A pair of jaws, having opposite ends, with a slot formed at one end, and a clamping protrusion provided on the inner side wall of the slot, the clamping protrusion being adapted to be inserted into one of the slots of the rotating body; and,
[0006] A handle, provided at the other end of the pair of jaws;
[0007] Wherein, when the handle is rotated forward, the pair of jaws can be used to relatively stop rotating with the rotating body, so that the rotating body rotates forward following the handle; when the handle is rotated backward, the pair of jaws can also be used to relatively stop rotating with the rotating body, so that the rotating body rotates backward following the handle.

[0035] The present utility model provides a wrench. Common furniture such as refrigerators and cabinets often have four adjusting feet installed on their bottom sides for lifting. The four adjusting feet are respectively installed at the four corners of the bottom side of the refrigerator. By controlling the lifting of each adjusting foot respectively, the refrigerator at the corresponding position can be driven to lift, and the levelness of the refrigerator can be adjusted. Thus, the levelness of the placement of the refrigerator can be adjusted. The adjusting foot includes an adjusting caster and an adjusting stud. The adjusting caster is a common rotating body, and the cross-section of the adjusting caster is circular. The adjusting stud is threadedly connected to the bottom side of the refrigerator. The adjusting caster is coaxially and fixedly connected to the adjusting stud. The adjusting caster includes a plurality of anti-slip teeth arranged at equal intervals on its circumferential side. A card slot is formed between adjacent anti-slip teeth. The cross-sectional size of the adjusting foot gradually increases from bottom to top. The length direction of the anti-slip teeth is parallel to the axial direction of the support column. The opening size of the card slot gradually increases from bottom to top. A wrench is often used to rotate the adjusting caster. A common wrench includes a handle and a jaw integrally connected. An arc-shaped groove is formed on the side of the jaw away from the handle. The arc-shaped groove can fit on the circumferential side of the adjusting caster. And a limiting tooth is fixedly arranged on the side wall of the arc-shaped groove. The limiting tooth is located at the end of the jaw away from the handle, and the cross-sectional size of the limiting tooth is less than or equal to the minimum opening of the card slot. When the arc-shaped groove of the jaw is abutted against the upper side of the adjusting caster, the limiting tooth can be located in the card slot, and the bottom wall of the arc-shaped groove is abutted against the circumferential side of the adjusting caster. When the handle is controlled to rotate towards the opening area close to the arc-shaped groove, the jaw can drive the adjusting caster to rotate; when the handle is controlled to rotate towards the opening area away from the arc-shaped groove, the side wall of the arc-shaped groove has a tendency to move away from the circumferential side of the adjusting caster, and the cross-sectional size of the limiting tooth is less than or equal to the minimum opening of the card slot, so the limiting tooth is easily detached from the adjusting caster; when it is necessary to adjust the adjusting caster to rotate in the reverse direction, it is necessary to adjust the opening direction of the arc-shaped groove of the jaw and reinstall the arc-shaped groove, which is relatively inconvenient for controlling the rotation of the adjusting foot.
[0036] Please refer to Figure 1 、 Figure 2 andFigure 3 In one embodiment of the utility model, the wrench is used to rotate the rotating body 200 having a plurality of slots 201 arranged in the circumferential direction, and the wrench comprises: a pliers head 1 having opposite two ends, one end of which is formed with a slot 11, and an inner side wall of the slot 11 is provided with a protrusion, and the protrusion is adapted to be inserted into one of the slots 201 of the rotating body 200; and a handle 2, which is arranged at the other end of the pliers head 1; wherein, when the handle 2 is rotated in the forward direction, the pliers head 1 can be used to relatively stop the rotation of the rotating body 200, so that the rotating body 200 follows the handle 2 to rotate in the forward direction; when the handle 2 is rotated in the reverse direction, the pliers head 1 can also be used to relatively stop the rotation of the rotating body 200, so that the rotating body 200 follows the handle 2 to rotate in the reverse direction.
[0037] The technical solution of the utility model can make the clamp head 1 be inserted into the clamp groove 201 after the clamp head 1 is installed on the rotating body 200; by holding and rotating the handle 2, the clamp head 1 can be driven to rotate forward or reverse around the axis of the rotating body 200; when the clamp head 1 rotates forward, the clamp head 1 and the rotating body 200 are relatively fixed, so that the clamp head 1 drives the rotating body 200 to rotate forward; when the clamp head 1 rotates reversely, the clamp head 1 and the rotating body 200 are relatively fixed, so that the clamp head 1 drives the rotating body 200 to rotate reversely; after the installation of the clamp head 1 is completed, by controlling the handle 2 to rotate forward or reverse, the clamp head 1 can drive the rotating body 200 to rotate forward or reverse with the clamp head 1; the problem of inconvenient rotation control of the adjustment foot is improved.
[0038] The slot 11 may be an expanding slot or a shrinking slot. When the slot 11 is an expanding slot, the opening size of the slot 11 is the maximum opening of the slot 11. When the pliers head 1 is brought close to the rotating body 200 from the side, the latching protrusion is arranged in the middle area of the slot 11. The latching protrusion may be one or more. When the pliers head 1 is rotated forward, the slot 11 on the side of the latching protrusion close to the rotation direction can abut against the outer peripheral side of the rotating body 200. The slot 11 cooperates with the rotating body 200 to reduce the latching protrusion from the latching slot 201.
[0039] When the pliers head 1 is rotated in the reverse direction, the slot 11 on the side of the clamping projection close to the rotation direction can abut against the outer peripheral side of the rotating body 200, and the slot 11 cooperates with the rotating body 200 to reduce the bulge of the clamping projection from the slot 201. When the pliers head 1 is rotated in the forward or reverse direction, the bulge of the clamping projection is reduced from being disengaged from the slot 201, and the clamping projection can drive the rotating body 200 to rotate with the pliers head 1, thereby achieving relative anti-rotation of the pliers head 1 and the rotating body 200. After the pliers head 1 is installed, it can ensure that the rotating body 200 rotates in the forward or reverse direction with the pliers head 1.
[0040] When the slot 11 is a constricted slot, after the pliers head 1 is put on the rotating body 200 from the side, the pliers head 1 is controlled to move upward, so that part of the bottom wall of the slot 11 can be against the outer peripheral side of the rotating body 200, thereby limiting the pliers head 1 from coming out of the rotating body 200; the cam can be arranged on any area of the slot 11, and the cam can be one or more, as long as the cam is located in a slot 201. Holding and rotating the handle 2 can make the pliers head 1 rotate with the handle 2, and the pliers head 1 can limit the cam from coming out of the slot 201, and the cam rotates with the pliers head 1, and the cam can drive the rotating body 200 to rotate with the pliers head 1; the mutual rotation stop between the pliers head 1 and the rotating body 200 is realized.
[0041] Reference Figure 2 , Figure 3 and Figure 4 A stud is integrally fixedly connected to the rotating body 200, a bracket is fixedly installed on the bottom side of the refrigerator, and the stud is threadedly connected to the bracket. When the rotating body 200 is rotated in the forward direction, the stud rotates in the forward direction with the rotating body, so that the distance between the rotating body 200 and the bracket is increased, and the rotating body 200 is against the ground, so that the bracket can drive one side of the refrigerator to rise; when the rotating body 200 is rotated in the reverse direction, the stud rotates in the reverse direction with the rotating body 200, so that the distance between the rotating body 200 and the bracket is reduced, so that the bracket drives one side of the refrigerator to descend.
[0042] At least two clamping protrusions are provided, and the two clamping protrusions are adapted to be inserted into at least two clamping grooves 201 of the rotating body 200. The cooperation of the two clamping protrusions can further reduce the detachment of the clamping protrusions from the clamping grooves 201. The two clamping protrusions can be arranged adjacent to each other. When the clamping head 1 is rotated forward or backward, the slot 11 between the two clamping protrusions can abut against the outer peripheral side of the rotating body 200, reducing the detachment of the two clamping protrusions from the clamping groove 201. Preferably, there is a spacing between the two clamping protrusions, increasing the size of the slot 11 between the two clamping protrusions. When the clamping head 1 is rotated forward or backward, the area of contact between the slot 11 between the two clamping protrusions and the outer peripheral side of the rotating body 200 is increased, further reducing the detachment of the clamping protrusions from the clamping groove 201 and enhancing the stability of the connection between the clamping head 1 and the rotating body 200.
[0043] Please refer to Figure 5 and Figure 6 , at least two of the clamping protrusions include two side clamping protrusions 3, and the two side clamping protrusions 3 are arranged opposite to each other along the width direction of the handle 2. The opening of the slot 11 between the two side clamping protrusions 3 is the largest. When the clamping head 1 is rotated forward or backward, the slot 11 between the two side clamping protrusions can abut against the outer peripheral side of the rotating body 200, reducing the detachment of the side clamping protrusions 3 from the clamping groove 201.
[0044] The inner wall surface of the slot 11 is provided as an arc surface; the central angle of the two side clamping protrusions 3 corresponding to the arc surface is 180°. The arc surface can fit and abut against the outer peripheral side of the rotating body 200, increasing the contact area between the slot 11 and the rotating body 200. When the clamping head 1 is rotated, the pressure between the clamping head 1 and the rotating body 200 is reduced, thereby reducing the deformation of the rotating body 200 and the clamping head 1. By ensuring that the distance between the two side clamping protrusions 3 is the largest, it is convenient to make the distance between the two side clamping protrusions 3 greater than the lower diameter of the rotating body 200, so as to conveniently sleeved the clamping head 1 on the lower side of the rotating body 200 from the side.
[0045] At least two of the clamping protrusions further include an intermediate clamping protrusion 4, and the intermediate clamping protrusion 4 is arranged between the two side clamping protrusions 3. When the clamping head 1 is rotated forward or backward, the intermediate clamping protrusion 4 is located in the clamping groove 201, and the intermediate clamping protrusion 4 can abut against the side wall of the clamping groove 201, which can drive the rotating body 200 to rotate with the clamping head 1, reducing the slippage between the rotating body 200 and the clamping head 1. The intermediate clamping protrusion 4 abuts against the side wall of the clamping groove 201, reducing the pressure on the rotating body 200 and reducing the deformation of the rotating body 200.
[0046] Please refer toFigure 5 and Figure 6 The middle clamping projection 4 is provided as one, and the central angle corresponding to the middle clamping projection 4 and one of the side clamping projections 3 with respect to the arc surface is 90°. By arranging the middle clamping projection 4 in the exact middle of the two side clamping projections 3, the sizes of the slots 11 on both sides of the middle clamping projection 4 can be made consistent. The middle clamping projection 4 is located on the central axis of the handle 2 extending along its length direction. When the handle 2 is rotated forward or backward, one side of a side clamping projection 3 close to the middle clamping projection 4 abuts against the side wall of the card slot 201, and the slot 11 abuts against the circumferential side of the rotating body 200, increasing the torque and enabling the handle 2 to be rotated more labor - savingly.
[0047] A plurality of the middle clamping projections 4 can be provided. The plurality of middle clamping projections 4 can drive the rotating body 200 to rotate with the clamp head 1 more stably. The plurality of middle clamping projections 4 abut against the bottom wall of the card slot 201, further reducing the pressure received by the rotating body 200 and further reducing the deformation generated by the rotating body 200.
[0048] The plurality of middle clamping projections 4 can be randomly arranged on the slots 11. The plurality of middle clamping projections 4 can also be symmetrically arranged along the central axis of the handle 2. The distance between adjacent middle clamping projections 4 can be equal to the opening size of a card slot 201, or can be an integer multiple of the opening size of a card slot 201; when the number of the middle clamping projections is even, the axis of the handle 2 is located between the two middle clamping projections 4 in the middle, and when the number of the middle clamping projections 4 is odd, the middle clamping projection 4 in the middle is located on the extension line of the axis of the handle 2.
[0049] In the thickness direction of the clamp head 1, the clamping projection has a gradually decreasing tapered introduction section; when the clamp head 1 is sleeved onto the rotating body 200, the handle 2 is rotated and adjusted so that the tapered introduction section of the clamping projection is located at the upper end of the clamping projection. Then, after the clamp head 1 is sleeved onto the rotating body 200 from the bottom side of the rotating body 200, the clamping projection is not inserted into the card slot 201. By controlling the upward movement of the clamp head 1, the smallest end of the tapered introduction section can be aligned and inserted into the card slot 201, and the tapered introduction section facilitates the insertion of the clamping projection into the card slot 201.
[0050] The card projection further has a continuous section, which is integrally connected to the maximum end of the gradual introduction section, and the cross-section of the continuous section is consistent with the cross-section of the maximum end of the gradual introduction section. When the clamping head 1 rotates, the continuous section abuts against the side wall of the card slot 201, which can reduce the force exerted on the clamping head 1 along the axial direction of the rotating body 200, and when the clamping head 1 drives the rotating body 200 to rotate, it can reduce the movement of the clamping head 1 along the axial direction of the rotating body 200.
[0051] Please refer to Figure 5 and Figure 6 , the clamping head 1 and the handle 2 are integrally formed. Both the clamping head 1 and the handle 2 are rigid members. Preferably, both the clamping head 1 and the handle 2 are steel structural members, which ensures the strength of the wrench. The processing methods between the clamping head 1 and the handle 2 can be casting, stamping, cutting, welding, etc.
[0052] A hanging hole 21 is provided at one end of the handle 2 away from the clamping head 1. After passing a hook through the hanging hole 21, it is convenient to hang the wrench on the hook, which is convenient for storing the wrench.
[0053] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
