Description
[technical field]
The utility model relates to a kind of hand-operated tools, specifically a kind of novel ratchet spanner.
[background technology]
Ratchet spanner is a kind ofly endways dissimilar tool heads can be installed, in order to be rotated with or to outward winding as the spanner of fixation kits such as hex bolts, at present, existing ratchet spanner is when being rotated with or outwarding winding fixation kit, all need the space of certain rotatable handgrip to work, the space of rotation is inconvenient more when the clavula wheel spanner is used more, and operating efficiency is also low more.In addition, after the terminal tool heads of installing of ratchet spanner is used, the phenomenon that is difficult to pull up appears through regular meeting.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of novel ratchet spanner is provided, and is not subjected to the influence in space during work, and rotary speed can be regulated, and can easily withdraw from after the terminal tool heads of installing of ratchet spanner is used.
Design a kind of novel ratchet spanner for achieving the above object, comprise the rotation gear piece, the commutation lid, rake tooth, handle, the H handle, overhead gage, mandrel, square toes and shaft head gear are formed, the left end that it is characterized in that the H handle is provided with driving head, vertically form the young ladder cylinder groove in the big lower end of upper port in the driving head, the cylinder groove inwall that the lower end is young is shaped on ring gear, H handle right side has the circular hole that communicates with sleeve, be provided with handle in the circular hole, the handle left end is provided with shaft head gear, in the cylinder groove of driving head upper end the rotation gear piece is housed, rotation gear piece lower surface connects overhead gage, and overhead gage has circular hole on the lower surface, be provided with straight pin in the circular hole, rake tooth is housed on the straight pin, and the other end of straight pin connects oral, has the jump ring groove on the oral lateral wall, in the jump ring groove flat spring is housed, oral lower end is provided with square toes, and the square toes lower surface has centre bore, is provided with mandrel in the centre bore, the mandrel upper surface connects ejector spring, and the ejector spring other end connects commutation and covers the bottom; Commutation is covered inside, bottom and is provided with horizontal hollow pins, is provided with the hollow pins spring in the hollow pins; The square toes left side has circular hole, is provided with the square toes steel ball in the circular hole, and has groove on the corresponding mandrel of the square toes steel ball surface; Have circular hole on the H handle right-hand member outer wall, be provided with positioning ball in the circular hole, and have locating slot on the corresponding handle outer surface of positioning ball, the peripheral spring lasso that adopts of positioning ball is fixed.
The utility model is compared with prior art, novel structure, easy to use, quick safety again, be not subjected to the influence of working space, can be soon, in, the pulling and regulate and have and move back the instrument sleeve arrangement of slow three kinds of speed, in addition, the utility model small investment, cost are low, are worthy of promotion and application.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Be the rotation gear piece referring to accompanying drawing 1,1,2 are the commutation lid, and 3 is oral, and 4 is rake tooth, 5 is hollow pins, and 6 is locating slot, and 7 is positioning ball, and 8 is the spring lasso, 9 is handle, and 10 is the H handle, and 11 is flat spring, and 12 is straight pin, 13 is ejector spring, and 14 is the square toes steel ball, and 15 is groove, and 16 is overhead gage, 17 is the jump ring groove, and 18 is mandrel, and 19 is square toes, and 20 is shaft head gear, 21 is ring gear, and 22 is the hollow pins spring, and 23 is driving head, and 24 is screw.
[specific embodiment]
Be described further below in conjunction with accompanying drawing:
Referring to Fig. 1, when the shaft head gear (20) of handle (9) left end of handle (9) spanner when closing up and the gear ring engagement of rotation gear piece (1) lower surface, rotary handle (9) just can drive the instrument sleeve and make slow rotation, and its rotation direction is controlled and regulated by the commutation lid (2) on top; When handle (9) is pulled out from H handle (10) and located by the positioning ball (7) in the spring lasso (8) that is enclosed within on the axle, make it slippage not become quaternity, at this moment, shaft head gear (20) breaks away from the gear ring of rotation gear piece (1), make the rake tooth (4) and spanner ring gear (21) engagement on both sides, by lid (2) the conversion left and right directions that commutates, the interlock power of rake tooth (4) comes freely to be contained in the interior hollow pins spring (22) of hollow pins (5) on commutation lid (2) lower end.The location of rake tooth (4) is located by straight pin (12), the two ends of straight pin (12) are to be set on oral (3) and the upper stop piece (16), oral (3) disjunctor also has square toes (19), square toes steel ball (14) is housed on the square toes (19), and have jump ring groove (17) in oral (3) outer ring, flat spring (11) is housed in the jump ring groove (17) blocks the interior combination core body of spanner, it can not be come off.For making the instrument sleeve can withdraw from square toes (19) fast, also can returning quickly after ejector spring (13) is housed on the mandrel (18) allows mandrel (18) eject, the manufacturing technology of this product and implementation method are very clearly concerning this professional people.
