Abstract
The utility model discloses a tongs type double-clamping wrench which is composed of wrench head portions, clamping ports and handles. The clamping ports comprise fixed-size openings and work ends with hexagonal holes or dodecagonal holes. Two wrenches in the same direction and the same plane are combined into one wrench through a common rotating shaft behind the two wrench head portions. The wrench can be effectively prevented from sliding out of a hexagonal nut by closing or opening the two handles and is especially suitable for locking hexagonal nuts and operation of a locking device of the locking hexagonal nuts.
Description
Technical field
The utility model relates to a kind of pliers type Double pawl spanner.Be suitable for fastening and unscrew hex nut, particularly be suitable for fastening and unscrew hexagonal locknut and locking device.
Background technology
By Wrench head, bayonet socket and handle opening that form, that have fixed dimension, have the spanner of the working end in band hexagon ring or 12 jiaos of holes, be to use conveniently in outstanding advantage fastening and when unscrewing hex nut.But the open defect that exists spanner to skid off from hex nut.
On March 26th, 2013, the applicant has proposed one and has been called the utility application of " hexagonal locknut and locking device thereof ".This utility model is by being set to be with externally threaded hollow cylinder and cylindrical hole slot respectively on the mutual corresponding end face of the pad of nut body and thickening, and spring washer is arranged on the hollow cylinder in the form of a ring, make nut body, pad and spring washer organically be combined into a whole mechanism.This mechanism is easy to use, has good anti-loosing effect.But when using, this whole mechanism is put after bolt screws, need again pad to make screw thread inflexibly interlock nut body and pad on to screw mutually with nut body in the other direction, also can not become flexible even just can reach the long-time strenuous vibration of plant equipment.Existing spanner is difficult to competent this operation on the market.Like this, just need a kind of combined type spanner that pad can be screwed mutually with opposite direction and nut body.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of fastening and can prevent that spanner from skidding off, particularly being suitable for fastening and unscrew the spanner of hexagonal locknut and locking device thereof from hex nut when unscrewing hex nut.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: be made up of Wrench head, bayonet socket and handle, bayonet socket can have fixed dimension opening, have the pliers type Double pawl spanner of the working end in band hexagon ring or 12 jiaos of holes, Wrench head, bayonet socket and handle and same direction, conplane Wrench head A, bayonet socket A and handle A are provided with a common rotating shaft at Wrench head and Wrench head A back.
Described handle and handle A preferably inwardly or outwards are the curved arc structure.
The utility model has the advantages that: owing to will be formed by Wrench head, bayonet socket and handle, bayonet socket has the opening of fixed dimension, two spanners with the working end in band hexagon ring or 12 jiaos of holes are combined into a spanner on same direction, same plane by the common rotating shaft in two Wrench head back, such spanner, when two handles merge, two bayonet sockets are fastening or unscrew hex nut simultaneously, when two handles open with opposite direction, just can prevent effectively that spanner from skidding off from hex nut; When two handles merge, two bayonet sockets are fastening or unscrew hex nut and locking device thereof respectively, after screwing, two handles are to open in the other direction, pad is screwed with nut body mutually with opposite direction, screw thread on nut body and the pad is interlock inflexibly just, also is such operation in the time of need unscrewing hex nut and locking device thereof.Two handles inwardly or outwards are the curved arc structure and then are conducive to two handles to open or closure in the other direction.
Description of drawings
