Abstract
The utility model relates to a sleeve type adjustable wrench, which is suitable for a nut with a sleeve capable of assembling and disassembling various specifications. The drill chuck is characterized in that the drill chuck is provided with three clamping jaws similar to a drill chuck for a drilling machine, and the three clamping jaws can slide up and down in an inclined through hole of a main sleeve under the action of screw threads meshed by an auxiliary sleeve and the three clamping jaws, so that a hexagonal inner hole surrounded by the lower parts of the three clamping jaws is enlarged or reduced. Therefore, the nut clamp can meet the requirement of clamping nuts of various specifications, and then the purpose of dismounting the nuts of various specifications is achieved by turning the square hole at the upper part of the main sleeve by the ratchet wrench. The utility model has the advantages of simple structure, low cost, convenient carrying and use.
Description
The utility model relates to a kind of telescopic adjustable spanner.
In the telescopic spanner that uses, a kind of sleeve can only be applicable to specifications of nuts of the same race at present, therefore exists following deficiency: the one, and specification is many, thus the cost height.The 2nd, be not easy to carry and use.
The purpose of this utility model is existing a kind of sleeve is improved to the spanner of the nut that can be used for plurality of specifications.
Task of the present utility model is finished by following method, and it is made up of parts such as chuck, main cover, pair cover and flat cover Sheet.The structure of chuck is to be analogous to the drilling machine drill chuck, it is surrounded by three jaws that are equal to, the lower inside of every jaw all has the angle of 120 degree, above position, bottom leans outward, and certain oblique angle is all arranged with its underpart, the lateral surface of jaw is a circular arc shaped, the inboard at its flare position is crescent shape and screw thread is arranged, this screw thread is become by a cutter car with the screw thread of other two jaws that are equal to, after three jaws surround, its underpart is hexagonal endoporus because the angle of 120 degree is respectively arranged thereby formed one.Main cover is to be become by a cylinder car, and its outer surface is circular, and inside is annular blind hole, the internal diameter of annular blind hole then pushes up the external diameter of the cylindrical barrel body on plane for stretching out in annular blind hole, the top outer circumference surface of this cylindrical barrel body has a step, and inside is a through hole, and the top of through hole is square.Between the outer circumferential surface of main cover and the outer circumference surface of its cylindrical barrel body, be drilled with three uniform oblique through holes of 120 degree from through its outer circumference surface of main cover bottom surface beginning, the prolongation intersection point of the center line of these three oblique through holes, all come together in main cover center line a bit on, and the oblique angle of its each oblique through hole all is complementary with the camber angle on three jaw tops of chuck.The last plane of main cover is drilled with four uniform screws.Paying cover is a similar cylindrical shell.The bottom of its outer circumference surface is tapered, and screw thread is arranged on the taper surface, and the screw thread on three jaws of this screw thread and chuck is complementary, so that after the assembling, be meshed with it.Step is arranged at the top of paying the outer circumference surface of cover, and step has annular knurl with the upper part, and the inside of paying cover is through hole, but the central authorities of step Ping Gai Sheet are also arranged at the top of its through hole is through hole, is drilled with four uniform screws on the ring surface, and four screws on the last plane of this screw and main cover are complementary.According to the structure of above-mentioned part, three jaws that just can make chuck insert three oblique through holes that corresponding master puts respectively after surrounding by the hand of spiral of its screw thread.Because pair cover is meshed the screw thread of the screw thread on its taper surface with three jaw upper inner faces of chuck be inserted in its annular blind hole above main cover after again.Like this, as long as twist the annular knurl position of paying on the outer circumference surface of cover top, three jaws that can drive chuck by the screw thread of engagement slide up and down in three oblique through holes of main cover.Therefore the hexagonal internal bore that the bottom surrounded of three jaws of chuck also just enlarges along with three sliding up and down of jaw or dwindles, thereby can adapt to the needs of the size of plurality of specifications nut.So mounting or dismounting are during nut, earlier three jaw bottoms of chuck are surrounded the hexagonal internal bore of being formed the back be inserted in wait to install and remove nut after, again the ratchet spanner grip is become owner of the cubic hole on the cylindrical barrel body top in the cover.Like this as long as switching ratchet spanner handle just can make moment be delivered on three jaws of chuck by the oblique through hole of main cover, thereby install and remove nut.Also can before ratchet spanner is switching, twist the annular knurl position of paying cover a little, make the hexagonal internal bore after its jaw bottom surrounds, after treating mounting or dismounting nut having certain pretension, come the switching ratchet spanner again installing and removing nut.When paying cover and twist in order to make, the axial displacement that three jaws that drive chuck by its screw thread slide up and down in three oblique through holes of main cover is controlled, its upper limit can be blocked a step of paying on the cover outer circumference surface and finished by the flat Sheet that cover, and its lower limit is then run into the main step that overlaps the outer circumference surface top of inner cylindrical barrel body by a step of paying cover endoporus top and limited.
The utility model has the advantages that simple in structurely, cost is low, carries with easy to use.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the A-A longitudinal sectional view of the utility model accompanying drawing 2.
Accompanying drawing 2 is that the B-B of the utility model accompanying drawing 1 is to view.
---chuck 2---flat deck wherein: 1
3---main covers 4---are paid cover
With reference to accompanying drawing: three jaws of chuck (1), respectively in three oblique through holes of the corresponding main cover of insertion (3).Pay cover (4) cover and become owner of the annular blind hole of cover (3), and its endoporus is placed on the outer circumference surface of the inner cylindrical barrel body of main cover (3).The taper screw thread of paying cover (4) bottom then with the flare position of three jaws of chuck (1) on medial surface on screw thread be meshed.Ping Gai Sheet (2) is the last plane that is loaded on main cover (3), and is fixed by bolt, and its endoporus then is enclosed within on the outer circumference surface of paying cover (4) top.
