A certain gap is reserved between the rotating shaft and the limiting plate, the multiple clamping teeth are clamped in the opening part and connected together in series through the rotating shaft, and the multiple clamping teeth can rotate around the rotating shaft within the range of 90 degrees under the limitation of the limiting plate and the bottom of the opening part, so that the size of the use space of the opening part is changed; and to-be-disassembled bolts of different specifications can be quickly adapted. The adjustable spanner solves the problems that an existing adjustable spanner is labor-consuming, time-consuming and low in work efficiency in the using process.

Description

Technical Field

[0001] The utility model relates to the technical field of movable wrenches, in particular to a novel quick-adjustable movable wrench. Background Art

[0002] The adjustable wrench is one of the most common tools. The existing traditional adjustable wrench has the function of adjusting the size of the jaws, but the opening and closing and adjustment of the jaws require visual inspection of the nut size, preliminary adjustment of the jaw size, and then putting the wrench on the nut. Finally, it needs to be adjusted in place before it can be used. It is laborious, time-consuming, and inefficient. Sometimes the initial adjustment opening is too small and needs to be readjusted. Utility Model Content

[0003] The utility model aims to overcome the deficiencies in the prior art and provide a novel quick-adjustable movable wrench, which solves the problems of laborious and time-consuming use and low efficiency of the current movable wrench.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A novel quick-adjustable movable spanner comprises a spanner body (1) and latching teeth (3), characterized in that an opening portion (2) is provided at one end of the spanner body (1), a rotating shaft (4) is fixedly mounted at the end of the opening portion (2) away from the opening direction, a limiting plate (5) is fixed to the side of the rotating shaft (4) by welding, a certain gap is retained between the rotating shaft (4) and the limiting plate (5), a plurality of latching teeth (3) are clamped in the opening portion (2) and connected in series through the rotating shaft (4), and under the restriction of the limiting plate (5) and the bottom of the opening portion (2), the plurality of latching teeth (3) can rotate around the rotating shaft (4) within a range of 90°.

[0006] Preferably, under the restriction of the limiting plate (5), the two side surfaces of all the locking teeth (3) can be flush with the two side surfaces of the wrench body (1).

[0007] Preferably, under the restriction of the bottom of the opening (2), all the latching teeth (3) can be perpendicular to the wrench body (1).

[0008] Preferably, a placement hole (6) is further provided at one end of the wrench body (1) away from the opening portion (2).

[0009] The utility model has a beneficial effect: the utility model changes the size of the usable space of the opening (2) by rotating the clamping teeth (3) around the rotating shaft (4) by 90 degrees, thereby quickly adapting to the clamping operation of bolts (7) to be disassembled of different specifications before disassembly, thereby improving the disassembly efficiency.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] like Figure 1-3 A novel quick-adjustable movable spanner is shown, comprising a spanner body (1) and latching teeth (3), characterized in that an opening portion (2) is provided at one end of the spanner body (1), a rotating shaft (4) is fixedly mounted at the end of the opening portion (2) away from the opening direction, a limiting plate (5) is fixed to the side of the rotating shaft (4) by welding, a certain gap is retained between the rotating shaft (4) and the limiting plate (5), a plurality of latching teeth (3) are clamped in the opening portion (2) and are connected in series through the rotating shaft (4), and under the restriction of the limiting plate (5) and the bottom of the opening portion (2), the plurality of latching teeth (3) can rotate around the rotating shaft (4) within a range of 90°.

[0016] Preferably, under the restriction of the limiting plate (5), the two side surfaces of all the locking teeth (3) can be flush with the two side surfaces of the wrench body (1).

[0017] Preferably, under the restriction of the bottom of the opening (2), all the latching teeth (3) can be perpendicular to the wrench body (1).

[0018] Preferably, a placement hole (6) is further provided at one end of the wrench body (1) away from the opening (2).

[0019] The utility model is implemented in such a way that when the movable spanner is not in use, each of the latch teeth (3) is close to each other, and under the restriction of the limit plate (5), the two side surfaces of all the latch teeth (3) can be flush with the two side surfaces of the spanner body (1). When in use, the opening portion (2) of the movable spanner is close to the bolt (7) to be removed, so that the latch teeth (3) corresponding to the bolt (7) to be removed are rotated 90 degrees around the rotation axis (4), and the latch teeth (3) in the opening portion (2) that have not rotated just clamp the bolt (7) to be removed in the middle, and then the removal work of the bolt (7) to be removed can be completed immediately.

[0020] The above-mentioned implementation mode is an illustration of the present utility model, not a limitation of the present utility model. It can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The protection scope of the present utility model is limited by the attached claims and their equivalents.
