Description

Combined turning and drilling tool

The utility model relates to a kind of hand tools, and especially a kind of fast switching series of combination is revolved tool and drilling tool.

At present, known screw assemblage does not possess the boring function, and translation function is slow, operating efficiency is lower, and cost of manufacture is higher.

The new purpose of this practicality is will provide a kind of efficient fast to switch that series of combination is revolved, drilling tool, adopts the fast socket that switches, and finishes the quick switching of difference in functionality, can also join in this socket and plug in fluted drill and screw tap, finishes boring and tapping operation.Instrument is made

The shape bar efficiently revolves, drilling tool and distortion is revolved, drilling tool, makes the work efficiency of instrument improve three times, operate comfortable flexibly especially, output torque greatly, safety labor-saving, reliability and durability.

The purpose of this utility model is achieved in that a kind of fast switching series of combination is revolved, drilling tool, by rotary handle, pay swing arm, stick-shaped handle, band ratchet swing arm, switch socket and various sword spare head soon and be linked in sequence and form, it is characterized in that making up revolve, drilling tool

Shape structure is the central axis along stick-shaped handle (31), opens can insert in a centre bore (33), the centre bore (33) and pays a swing arm (35), pays swing arm (35) and goes up cover and load onto rotary handle (21) and be similar to outside forming

Revolving of shape crank handle state, drilling tool, 360 ° of continuous rotary works radially, this revolves, the turning moment of drilling tool output is delivered on the various sword spare heads by fast switching socket (6), the fast structure that switches socket (6) is at the horizontal Baltimore groove (3) of opening of the front end of swing arm (2), the steel sleeve (5) of one section band non-return card (8) is promptly formed fast switching socket (6) with the front end that rivet (7) is riveted on swing arm (2), non-return card (8) is an elastic steel sheet, its front end left side has a bail (9) to pass locating hole (10) on the sleeve pipe (5) to snap in the non-return hole (11) on the sword spare head, does not come off when making the various sword spare heads work of inserting in the socket (6).Fast switch can join in the socket (6) insert variously revolve, drilling tool sword spare head carries out work, can join and insert flat blade screwdriver and a crosspoint tip screwdriver screw blade spare head (A) and (B), join and insert hexagonal tenon sword spare head and impact wrench chieftain and form and revolve tool, also can join and insert straight (E), threaded bore (F), fluted drill (G) and screw tap (H) the composition drilling tool of boring of point.The end of various sword spare heads is all made convex tenon (4), and Baltimore groove (3) tight engagement on convex tenon (4) and the swing arm (2) will be revolved square reliably and is transferred to and finish different work on the sword spare head.Fast to switch socket (6) translation function quick and convenient, need only dial non-return card (8) during operation, pulls up the sword spare head that no sword spare head inserts need usefulness again and can work.

Fast the revolving of series is revolved, drilling tool can be made three kinds of different operating states plurality of specifications, the drilling tool of switching.Introduce the structure of the revolving of three kinds of different operating states, drilling tool below: (one) portable straight-bar screw assemblage, its duty is the same with the normal screws cutter, mould handle direct rotary bar (2) and go up the equipped fast socket (6) that switches of, be equipped with sword spare head (A), (B), (C), (E), (F).Various sword spare heads are concentrated and are inserted in a cylindrical sword spare box (13), and an inserted link (14) is arranged on the central axis of sword spare box (13), and inserted link (14) also can insert in the socket (6) and revolve tool and join together, is easy to carry.A link (15) is arranged on the inserted link (14), can load onto the side electric installation in the handle of plastics (1) and survey.

(2)

The shape swing arm efficiently revolves, drilling tool, it is characterized in that: swing arm separates with handle, and handle is made rotary handle (21), swing arm is made Shape swing arm (22), The front end of shape swing arm (22) is equipped the fast socket (6) that switches, and its end is made sphere and inserted in the centre bore of rotary handle (21) (23), hold rotary handle (21) with

The front end of swing arm (22) is that axle is done 360 ° of radially rotations, to sword spare head (G) output turning moment, finish revolve, drilling tool work.(3) distortion revolve, drilling tool, this instrument has the reciprocating type and two kinds of duty deformables of continuous rotary of ratchet to select for use.Revolve tool and make the ratchet stick-shaped and revolve tool,, band ratchet swing arm (32), switch socket (6) and rotation direction selection mechanism (34) soon and form by stick-shaped handle (31).Distortion is revolved, the feature of drilling tool is: bore a deep hole (33) along stick-shaped handle (31) center line, insert L shaped pair of swing arm (35) in the deep hole (33), and put rotary handle (21), the ratchet-type stick-shaped revolves tool and just is deformed into

Shape is rotary revolves, drilling tool, pays the insertion depth of swing arm (35) and regulates the location by ending a screw (36), regulates to pay the degree of depth that swing arm (35) inserts and be equivalent to regulate

The size of shape swing arm turning moment is to adapt to different needs.This instrument can be mixed power-assisted handle (41) bimanualness, power-assisted handle (41) at ordinary times with revolve tool and separate, need the time spent easily in the clamping, its clamp structure uniqueness, the rear and front end difference, the front end of retained part is made bending fork mouth (42) rear end and is made bar shaped crotch (43), during clamping earlier with fork mouth (42) fork toward the anterior of swing arm (32) and be against the terminal wide shoulder of sleeve pipe (5), the bar shaped crotch (43) of rear end hooks swing arm (32), left hand is held power-assisted handle (41) plus-pressure forward, clamp structure is hook just in time, card clamps swing arm (32), swing arm (32) still can rotate freely, and the both hands cooperating can be exported than high pulling torque and pressure to adapt to tapping, boring, with the needs that revolve the wood screw great dynamics.

The utility model has the advantages that: adopt and cut socket soon, can switch different functions fast, socket can be joined plug in fluted drill and screw tap is made drilling tool and tapping tool, increased function of use, work efficiency improves more than three times, distortion is revolved, drilling tool uses more flexible comfortable, high-effective and labour-saving, cost of manufacture is cheap, originally revolves, prodigiosin output revolves square and pressure more greatly, and is reliability and durability.
