Abstract
A dual-purpose compact ratchet socket wrench works in two modes, one as ordinary ratchet wrench and another featuring that its ratchet mechanism is driven by driver. Bevel ring gear, eccentic ratchet, commutator and drive rod are arranged in its wrench body for compact structure. One end of drive rod is made into bevel gear and another end is a hexagonal rod and optionally, the rod has spherical hexahedron end for multi-angle working.
Description
The present invention relates to a kind of invention to the box socket set architecture advances.
Existing box socket set, mostly function singleness promptly can only adopt the hand-driven mode to work separately, and the Wrench head volume is big, and the space of use is subjected to certain limitation; The ratchet mechanism joggled strength is relatively poor simultaneously, influences the service life of box socket set.
The purpose of this invention is to provide a kind of compact dual-purpose ratchet socket wrench, but it both manual work also can adopt power drive, and can overcome the shortcoming of above-mentioned prior art effectively.
Structure of the present invention is seen shown in the accompanying drawing.It comprises an annular head and the handle that is connected as a single entity with head, is provided with the ratchet driving mechanism in the annular head, it is characterized in that handle is a hollow shape, in be provided with a drive rod, one of drive rod is made the bevel gear shape, the other end make six shaft-like; Driving mechanism comprises driving shaft in the annular head, umbrella shape rim gear wheel, eccentric ratchet, commutator, and annular head inwall is shaped on the ratchet with eccentric ratchet engaged, and eccentric ratchet is hinged on the annular head, also is shaped on block in the annular head.
In the above-mentioned structure of the present invention, the axial line of the axial line of drive rod and sleeve driving shaft intersects vertically, driving shaft one end is made the square projection that can match with standard cartridges, distance is 1/4 inch between six a shaft-like end two parallel planes of drive rod, and six shaft-like terminations of drive rod can be made into six face ball shapes.
The present invention is simple in structure, the joggled strength height, and volume compact, the service efficiency height, and manually, power drive can separately work alone, and is independent of each other, and is a kind of desirable box socket set.
Below in conjunction with accompanying drawing embodiments of the invention are described:
Fig. 1 is a profile schematic diagram of the present invention,
Fig. 2 is a longitudinal sectional view of the present invention,
Fig. 3 is the transverse sectional view of Fig. 2,
Fig. 4 is the partial sectional view of annular head of the present invention,
Fig. 5 is that six rod end heads of drive rod are made schematic diagram behind six face balls in the handle.
In the above-mentioned accompanying drawing 1,2,3 of the present invention, described each parts all adopt steel material to make, its annular head 113 is made one with handle 102, handle 102 is a hollow form, in be provided with a drive rod 104, drive rod 104 is made bevel gear shape 108 by annular head 113 1 ends, and it is 1/4 inch so that join with the Power Drive Unit interface of standard that other end armrest handle 102 opening parts can be made into distance between six wantonly two parallel planes of shaft-like 106, six bars; In order to guarantee the drive rod 104 in also can driving handle 102 under the situation of driving shaft in off-centre of Power Drive Unit, 104 6 bar 106 terminations of drive rod can be by the six face ball shapes of making shown in Figure 5, driving mechanism comprises driving shaft 103 in Fig. 2,3, the 4 annular heads 113, bevel gear ring 110, eccentric ratchet 107, commutator 114; The main body 100 that ratchet mechanism is arranged in the annular head 113; Eccentric ratchet 107 is hinged in the annular head 113, and annular head 113 also is shaped on block 110, and sleeve driving shaft 103 1 ends are made the square projection that matches with the standard socket wrench cover, and the other end links to each other with ratchet mechanism three-dimensional 100.
The present invention can adopt manually or the power drive mode works alone.When using manual work, only need standard cartridges is connected under the driving shaft 103 square projectioies, be enclosed within on nut or the bolt, according to the direction that unscrews or screw, regulate the direction of commutator 114, promptly available hand is pulled the rotation of handle 102 front and back with turn nut, bolt.When driving with Power Drive Unit, need only be with the interface of Power Drive Unit, be enclosed within on 106 6 spherical terminations of drive rod of pinch bar 102 1 ends, thus by Power Drive Unit drive drive rod 106 and bevel gear ring 110 drive on the driving shafts 103 overlap standard cartridges and pull nut or bolt.Along with the driving of Power Drive Unit rotation, under the motionless situation of whole wrench body, nut or bolt just can be driven to rotate.
