Abstract
The invention relates to an adjustable ratchet wrench which comprises a ratchet device, six sets of spring linkage mechanisms, locking devices, six movable tooth openings and a connecting stress rod, wherein a fixed ratchet which is arranged outside the ratchet device and a fixed ratchet which is arranged inside the ratchet device are matched with six movable ratchets to form the ratchet device, the outer side of the fixed ratchet is connected with the connecting stress rod, the surface of each movable ratchet is connected with a connecting block, each set of spring linkage mechanisms is composed of two springs, each movable tooth opening slides inside each connecting block, and the locking devices are arranged on the surfaces of the movable tooth openings respectively. Compared with the prior art, the adjustable ratchet wrench has the advantages of being simple in structure, convenient to use, scientific and practical, due to the fact that an effect of replacing a multi-handle wrench by a one-handle wrench is achieved, maintenance cost is effectively reduced, the inconvenience brought when a user carries and uses the multi-handle wrench in a maintenance place is avoided, the maintenance period is shortened, and fastening and loosening of a bolt of a non-standard type are achieved.
Description
Technical field
The present invention relates to the machine tool technical field, particularly a kind of ratchet spanner of regulating.
Background technology
Spanner mainly is divided into the normal activity spanner, double offset ring spanner, fork spanner and ratchet spanner, at present, most popular spanner is the normal activity spanner, it is low that the normal activity spanner has operating efficiency, damage easily, to the bolt of specific position can't be fastening etc. shortcoming, and other spanner for fitted bolt has a lot of models, when using these spanners, for enterprise brings the certain economic burden, the one-tenth that causes produces cost and improves, simultaneously because when going out service work, need carry a large amount of spanners, the service work of going out is brought great inconvenience, increase staff's work load.
Summary of the invention
Fastening and the loosening ratchet spanner regulated that the purpose of this invention is to provide a kind of simple in structure, easy to use, suitable multiple model bolt.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of ratchet spanner of regulating, comprise ratchet device, six groups of spring link gears, locking device, six movable tooth mouths be connected force rod, described ratchet device is made up of the fixed ratchet wheel in the outside and six movable ratchets that match with fixed ratchet wheel, the fixed ratchet wheel outside be connected force rod and be connected, every activity ratchet surface is equipped with contiguous block, every group of spring link gear is made of two springs, one end of two springs all is fixed on the movable ratchet, wherein the other end of a spring is connected with contiguous block, the other end of another root spring passes contiguous block and is connected with movable tooth mouth, movable tooth mouth is in the contiguous block slides within, and movable tooth oral thermometer face is provided with locking device.
Described contiguous block is U-shaped arc structure, and U-shaped bottom surface is provided with fin.
Described activity ratchet surface is provided with groove, and constitutes concavo-convex chute connected mode with the fin of contiguous block.
Described fin middle part is provided with through hole.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of ratchet spanner of regulating, has simple in structure, easy to use, science practical characteristics, owing to use a handle spanner to replace the effect of number handle spanner work, effectively reduced maintenance cost, avoided the inconvenience of carrying and using number handle spanner to bring in maintenance sites, shorten the maintenance duration, realized fastening and loosening to non-standard model bolt.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further specified:
As Fig. 1～shown in Figure 4, a kind of ratchet spanner of regulating of the present invention, comprise ratchet device, six groups of spring link gears 3, locking device 4, six movable tooth mouths 6 be connected force rod 7, described ratchet device is made up of the fixed ratchet wheel 1 in the outside and six movable ratchets 2 that match with fixed ratchet wheel 1, fixed ratchet wheel 1 outside be connected force rod 7 and be connected, every movable ratchet 2 surfaces are equipped with contiguous block 5, every group of spring link gear 3 is made of two springs, one end of two springs all is fixed on the movable ratchet 2, wherein the other end of a spring is connected with contiguous block 5, the other end of another root spring passes contiguous block 5 and is connected with movable tooth mouth 6, movable tooth mouth 6 is in contiguous block 5 slides within, and movable tooth mouth 6 surfaces are provided with locking device 4; Described contiguous block 5 is U-shaped arc structure, and U-shaped bottom surface is provided with fin 8; Described movable ratchet 2 surfaces are provided with groove, and constitute concavo-convex chute connected mode with the fin 8 of contiguous block 5; Described fin 8 middle parts are provided with through hole 9, make things convenient for another root spring to pass through hole 9 and are connected with movable tooth mouth 6.
As shown in Figure 5, use when of the present invention, movable tooth mouth 6 is on the fastening bolt 10 of needs, utilize the drift angle of bolt 10 that movable tooth mouth 6 is strutted, because spring link gear 3 stressed contractions, drive activity tooth mouth 6 is retracted in the U-shaped groove of contiguous block 5, and make movable tooth mouth 6 be stuck in bolt 10 outsides, after being adjusted to correct position, utilize locking device 4 to carry out fixing and locking, bolt 10 just in time is in the middle of the movable tooth mouth 6, prevent that bolt from threading off when fastening, behind bolt 10 fixing and lockings, turn and connect force rod 7 and make fixed ratchet wheel 1 and movable ratchet 2 stressed, thereby make that being in bolt 10 among the movable tooth mouth 6 carries out fastening or play pine; Simultaneously because of the use of chaste tree wheel apparatus do not need with the present invention take off namely can carry out fastening or play loose same model bolt next time.
