Abstract

The utility model relates to an open and ratchet spanner, belonging to disassembling tools. The open and ratchet spanner is structurally characterized in that a pawl is connected with a handle by a screw I, the pawl and a ratchet are clamped, and an opening is arranged on the ratchet; and the side surface of one end of a spring leaf presses against the pawl, and the other end of the spring leaf is connected with the handle by a screw II; and an end cover is connected with the ratchet by a screw III. The open and ratchet spanner has the advantages that the structure is simple, the conception is novel, the use is convenient, and the distance between a jaw and the hexagon of a nut is not needed to be always adjusted when assembling and disassembling the nut; and the spanner needs a small space in operation and can disassemble the nut in the range from 10 degrees to 90 degrees, so that the practicability is strong.

Description

The open ratchet spanner

Technical field

The utility model relates to a kind of dismantling device, particularly a kind of open ratchet spanner.

Background technology

Present manual spanner mainly contains two kinds of opening spanner and ratchet spanners, and wherein, the opening spanner is in that space-constrained is local when using, constantly adjust pull mouthful and nut six sides between the position, inefficiency.Have the mouth of pulling of ratchet spanner to seal, some occasion is inapplicable, as is not suitable for the dismounting of tap.

Summary of the invention

The purpose of the utility model is to provide a kind of open ratchet spanner, has solved existing opening spanner and close mouth spanner and has needed big revolution space and need the repeatedly defective of suit.The utility model combines ratchet mechanism and opening spanner, will pull mouth and be designed to one with ratchet.Drive ratchet through pinch bar, ratchet drives ratchet, and the ratchet wrench mouth drives the transmission process realization motion of nut and the transmission of power.For preventing ratchet dislocation in the course of work, the spring leaf in the structure plays a part to make ratchet to reset.The ratchet number of teeth of spanner with pull mouthful basic size can seriation; The nut that is fit to different size; Angle between the ratchet number of teeth can be minimum to 10 °, and the number of teeth of ratchet also can be according to a plurality of pawl numbers that are dimensioned to of pulling mouthful, thereby transmit bigger power in littler space.

The above-mentioned purpose of the utility model realizes through following technical scheme:

The open ratchet spanner comprises ratchet 1, end cap 2, screw III 3, ratchet 4, screw I 5, handle 6, screw II 7 and spring leaf 8, and wherein, ratchet 4 is connected with handle 6 through screw I 5, and this ratchet 4 engages with ratchet 1, and this ratchet 1 is provided with opening; One end side surface of spring leaf 8 props up ratchet 4, and the other end is connected with handle 6 through screw II 7; End cap 2 is connected with ratchet 1 through screw III 3.

The beneficial effect of the utility model is: simple in structure, novel, easy to use, need not always adjust the position of pulling between mouth and nut six sides during dismounting nut; Requisite space is little during wrench operated, can between 10～90 °, pull down nut, and is practical.

The specific embodiment

Further specify the detailed content and the specific embodiment thereof of the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, the open ratchet spanner of the utility model comprises ratchet 1, end cap 2, screw III 3, ratchet 4, screw I 5, handle 6, screw II 7 and spring leaf 8, wherein; Ratchet 4 is connected with handle 6 through screw I 5; This ratchet 4 engages with ratchet 1, drives ratchet 4 by this handle 6 and stirs ratchet 1, and this ratchet 1 is provided with opening; This opening clamping nut is removed nut or tightens; One end side surface of spring leaf 8 props up ratchet 4, and the other end is connected with handle 6 through screw II 7, and this spring leaf 8 makes ratchet 4 returns; End cap 2 is connected with ratchet 1 through screw III 3, and makes handle 6 be in the tram, and handle 6 is come off from ratchet 1.

When the utility model used in reality, as to the right-handed nut, when rotating counterclockwise handle 6, ratchet 4 drove ratchet 1 and rotates, and is together rotated with ratchet 1 by the folder nut simultaneously; When clockwise rotating handle 6, ratchet 4 breaks away from ratchet 1 teeth groove, and ratchet 1 is motionless, constantly contrary clockwise fixed handle, and nut is removed.

When with nut screwing clamping, as long as with 180 ° of spanner counter-rotatings, constantly along the de-rotation handle, nut can be tightened then.

Claims

1. open ratchet spanner is characterized in that: ratchet (4) is connected with handle (6) through screw I (5), and this ratchet (4) engages with ratchet (1), and this ratchet (1) is provided with opening; One end side surface of spring leaf (8) props up ratchet (4), and the other end is connected with handle (6) through screw II (7), and end cap (2) is connected with ratchet (1) through screw III (3).
