Abstract
The utility model discloses a ratchet spanner which comprises clamping plates, a spanner head, a ratchet, a pin shaft, a spring sheet, and a ribbed slab. The utility model is characterized in that the clamping plates are respectively sheathed on the both sides of the spanner head whose surrounding is machined with ratchet teeth; the ratchet is arranged between two clamping plates through the pin shaft; a reset spring sheet is arranged on the ribbed slab. The utility model is especially suitable for using in narrow working occasions.
Description
The utility model belongs to hand tools, relates to a kind of ratchet spanner.
Spanner is an instrument commonly used in the activity in production, has variously, and as monkey wrench, box spanner, double offset ring spanner etc., but in some narrow occasions, it is inconvenient that these spanners are felt sometimes.Because tighten a bolt or nut, need to rotate a lot of weeks, and if spanner can not change 360 °, spanner will be taken down from bolt head, and then be selected suitable angle, repeat action last time.It is 88203981.4 Two-way spanner that Patent Office of the People's Republic of China discloses a kind of application number on February 15th, 1989, and this spanner can be realized two-way pulling, and shortcoming is a complex structure, need could realize by rack-and-pinion and knob, in addition, the manufacture craft difficulty.
The purpose of this utility model provides a kind of simple in structure, and is easy to use, spanner need not be broken away from from workpiece to realize the reverse ratchet spanner that freely rotates.
To achieve these goals, the utility model adopts a spanner, is set with clamping plate in the spanner both sides, is processed with the ratchet tooth in the spanner periphery, also has a ratchet that is meshed with ratchet on bearing pin, and a reseting spring leaf is arranged on the gusset between the clamping plate.
The utility model has the advantages that simple in structurely, can oppositely freely rotate and do not make workpiece stressed.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Describe in detail below in conjunction with accompanying drawing.
The utility model has a spanner 4, said spanner 4 is processed into the ratchet shape in periphery, be processed with in interior week and bolt or the corresponding interface of nut, also can be processed into the thread form of different shapes such as hexagonal, corner, be fixed with in spanner 4 both sides folder pull 1 and folder pull 6, pull the middle part at two folders a bearing pin 5 is installed, a ratchet 3 is arranged on bearing pin 5.Be screwed a muscle and pull between two folders are pulled, muscle is pulled a very flat groove, and a spring leaf 2 that ratchet is resetted is arranged in groove.
During use, the interface of spanner is enclosed within on the workpiece, and the position clockwise rotates as shown in Figure 1, because the engagement of ratchet and ratchet, forcing spanner and folder to pull synchronous rotation tightens workpiece, when rotating counterclockwise because that ratchet slides on ratchet is unrestricted, so folder pull 1 and folder pull 5 and can center on spanner and freely rotate, when pressing from both sides switching, repeat a last action again to correct position, like this, just whole spanner can be taken down from workpiece and be got final product repetitive operation, workpiece (as bolt) is tightened.If make the workpiece reverse rotation, only need spanner is broken away from workpiece, overturn put workpiece after 180 ° just can backwards rotation, do not need changement, simplify the structure, compared with prior art, this upset is not a shortcoming, advantage really on the contrary is not because therefore the effect of spanner or fastening workpiece or Panasonic's workpiece need changement just can satisfy two kinds of rotation directions.
