Abstract

The utility model provides an adjustable spanner with a positioning clamp and graduations, which is characterized in that a positioning clamp device is additionally arranged under the adjusting worm gear of an ordinary adjustable spanner, and dimension graduations and aligning arrows are engraved on the two sides of a spanner opening for solving the defects that when the ordinary adjustable spanner is used, the dimension of the spanner opening is easily changed and that the dimension of the spanner opening only can be adjusted on a wrenched object. The dimension of the spanner opening of the utility model can be directly adjusted according to the graduations and can be automatically positioned. The utility model which has the advantages of simple process, convenient operation, and actual using value is suitable for updating the ordinary adjustable spanner.

Description

Adjustable spanner with positioning clamp and graduation

The utility model belongs to the technological improvement of mechanical hand tools, is specifically related to a kind ofly have that locator card is stopped and the adjustable wrench of scale.

At present, all trades and professions are being extensive use of adjustable wrench in producing, keeping in repair, its defective is: pull mouthful size in use because of the effect of power, very easily change, need continuous re-adjustments or pressing the adjusting turbine of spanner to use with thumb, in addition, mouthful size is pulled in adjusting can only could regulate use to being pulled above the thing at quilt, in addition, the above-mentioned defective of the adjustable wrench that size is big more is serious more.But since common adjustable wrench to have the size adjustable scope of application wide, so be still people produce, one of indispensable important tool in the maintenance.

The purpose of this utility model is to provide a kind of characteristics that keep common adjustable wrench fully, and mouthful size of pulling of setting is not changed, and can directly regulate the novel adjustable wrench of location according to the size of pulling mouthful scale and being pulled thing.

The purpose of this utility model realizes as follows: below the adjusting turbine of common adjustable wrench, set up positioning brake device, this device be by the outer chute that increases of wrench body, in the wrench body the top spring and be contained on the chute and be in the locator card of regulating between turbine and the top spring and stop and constitute jointly.

The utility model removes has the characteristics of common adjustable wrench, and following advantage is still arranged: the one, and rational in infrastructure, the outward appearance novelty; Make easily, with low cost; The 2nd, automatic location is difficult for becoming flexible, and is easy to use, is easy to promote.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model side view.

By Fig. 1, shown in Figure 2, the utility model is to have additional locator card stop chute (5) and spring hole, top (7) below the turbine (3) of common adjustable wrench body (1), top spring (6) is housed in the spring hole, movable locator card stop (4) is housed in the chute above the spring of top, pull the scale (8) that is carved with various standard sizes in mouthful both sides, to adapt to country variant, the use habit in area, the arrow (9) of aiming at scale is carved with in movably pulling of spanner on mouthful (2), locator card is stopped (4) and the identical cambered surface of adjusting turbine (3) has the bigger hair side of friction, to increase the resistance that locator card is stopped, the width that locator card is stopped should equal to regulate 1.5 pitch of turbine, and become the ratio of 3:4 with length, the thickness that thickness should equal the spanner handle adds 2-3MM, and less than the diameter of regulating turbine, the position that locator card is stopped places to be regulated on the turbine length center line.

The utility model only need in use with thumb locator card is stopped (4) push away and regulate turbine (3), adjusting turbine with regard to adjustable spanner, after mouthful size is pulled in adjusting, unclamp thumb, just can use as fork spanner, skilled user can directly mix up the size of pulling mouth according to the scale of pulling mouth.

Claims

1, a kind of have that locator card is stopped and the adjustable wrench of scale, it is characterized in that: below the adjusting turbine (3) of common adjustable wrench, be provided with positioning brake device, this device be by the chute (5) of the outer processing of wrench body, in the wrench body top spring (6) and be contained on the chute and be in and regulate turbine (3) and the locator card between the spring of top (4) formation jointly of stopping.

2, according to claim 1 have that locator card is stopped and the adjustable wrench of scale, it is characterized in that: adjustable wrench body (1) pull the size scale (8) that is carved with different systems in mouthful both sides, aim at movably pulling above the size scale mouthful (2) and indicate and aim at arrow (9).
