Description
Technical Field
The utility model relates to a hardware and tools technical field especially relates to a simple and easy spanner with adjustable.
Background
The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other threaded connection firmware by utilizing the lever principle; the wrench is generally provided with an opening or a trepan for holding the bolt or the nut at one end or both ends of the handle portion, and when the wrench is used, the bolt or the nut can be screwed by applying an external force to the handle portion along the rotation direction of the thread.
Various multifunctional wrenches are various in types, complex and various at present; the traditional wrench has certain pertinence, but cannot meet the requirements of complex and various construction applications in a building site, and in most cases, one wrench can only disassemble one bolt or nut, or the adjustable wrench is only suitable for disassembling and assembling the bolt or nut within a certain size range; therefore, field constructors often need to carry the spanner of multiple model to the dismouting operation of reply all bolts or nuts, the work progress need frequently change corresponding spanner to the bolt or the nut of equidimension not, seriously reduces construction operation efficiency, when not having corresponding spanner or being directed against non-standard screw thread firmware, often leads to litter worker, influences the orderly of construction operation and goes on.
Disclosure of Invention
The utility model aims to solve the technical problem that a simple and easy spanner with adjustable is provided, the defect of traditional spanner dismouting operation is overcome to this simple and easy spanner, its simple structure, dismouting convenient operation, and the dismouting operation that can deal with wide range size bolt and nut and nonstandard screw thread firmware, improves the efficiency of operation, ensures going on in order of construction process.
For solving the technical problem, the utility model discloses simple and easy spanner with adjustable includes screw rod, connecting block and flexible fastening area, the connecting block is equipped with the screw between two parties, the screw rod twist in the screw of connecting block, flexible fastening area both ends are fixed connection respectively the both sides of connecting block.
Furthermore, this simple and easy spanner still includes twist grip, twist grip locates the screw rod top.
Furthermore, the flexible fastening belt is a chain, and two ends of the chain are connected with two sides of the connecting block by pin shafts or welding.
Further, flexible fastening area is high strength toughness billet, high strength toughness billet both ends with the both sides of connecting block are through welded connection.
Further, the diameter of the screw is larger than 12 mm.
Because the utility model discloses adjustable simple and easy spanner has adopted above-mentioned technical scheme, this simple and easy spanner includes screw rod, connecting block and flexible fastening area promptly, the connecting block is equipped with the screw between two parties, the screw rod twist in the screw of connecting block, flexible fastening area both ends are fixed connection respectively the both sides of connecting block, flexible fastening area is chain or high strength toughness billet. This simple and easy spanner overcomes the defect of traditional spanner dismouting operation, its simple structure, dismouting convenient operation, and can deal with the dismouting operation of wide range size bolt and nut and nonstandard screw thread firmware, improve the efficiency of operation, ensure going on in order of construction process.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic view of the adjustable simple wrench of the present invention.
Detailed Description
Embodiment is shown in fig. 1, the utility model discloses simple and easy spanner with adjustable includes screw rod 1, connecting block 2 and flexible fastening area 3, connecting block 2 is equipped with the screw between two parties, screw rod 1 twist in the screw hole of connecting block 2, 3 both ends difference fixed connection in flexible fastening area the both sides of connecting block 2.
Preferably, the simple wrench further comprises a rotating handle 4, and the rotating handle 4 is arranged at the top end of the screw rod 1. The rotating handle is convenient for implement the rotation operation to the screw rod, improves the convenience of this simple and easy spanner operation.
Preferably, the flexible fastening belt 3 is a chain, and two ends of the chain are connected with two sides of the connecting block 2 by pin shafts or welding.
Preferably, the flexible fastening belt 3 is a high-strength and tough steel bar, and two ends of the high-strength and tough steel bar are connected with two sides of the connecting block 2 by welding.
Flexible fastening area can select for use the banding body that has certain frictional force and toughness material in this simple and easy spanner, like chain or high strength toughness billet etc. is convenient for hold tightly under the application of force of screw rod by dismouting bolt or nut to apply certain radial effort to bolt or nut.
Preferably, the diameter of the screw is greater than 12 mm. Because this simple and easy spanner dismouting bolt or nut applys certain effort by the screw rod, consequently the screw rod needs to have certain rigidity, and the screw rod of overgauge easily takes place the bending at the application of force in-process, leads to the inefficacy of bolt or nut dismouting.
The simple wrench overcomes the defects in the prior art, and has the advantages of simple structure, convenient manufacture and wide application; when the dismounting operation of the bolt, the nut or the non-standard firmware is performed, the flexible fastening belt 3 is sleeved into the dismounted part 5, the screw rod 1 is rotated by the rotary handle 4 until the bottom end of the screw rod 1 abuts against the dismounted part 5, at the moment, the flexible fastening belt 3 is used as a main stress link, the friction force between the flexible fastening belt 3 and the dismounted part 5 is increased until the screwing force of the dismounted part 5 is overcome, and the screw rod 1 is rotated along the thread direction of the dismounted part 5, so that the dismounting operation of the dismounted part 5 can be realized. Or the positions of the screw rod 1 and the connecting block 2 can be fixed, and the same purpose can be achieved by adjusting the length of the flexible fastening belt 3.
This simple and easy spanner is applicable to the dismouting of various threaded connection fasteners, satisfies the needs of site operation, need not frequently to change the dismouting operation that the traditional spanner of different specifications can deal with various fasteners, and portable improves the efficiency of dismouting operation, ensures going on in order of construction process.
