Abstract
The utility model discloses a kind of hex-head nut spanner, comprise plastic shell, inner casing, plastic cover, knife bar, sleeve jump ring, pinion stand, gear, torsion spring and plug screw, described jump ring, pinion stand, gear, torsion spring are set in knife bar successively, and are completely installed in inner casing; Spacing by jump ring bottom pinion stand; Inner casing is installed in plastic shell, and knife bar stretches out plastic shell; Plug screw connects inner casing, and plastic shell top connects plastic cover.This hex-head nut spanner that the utility model relates to, structure is simple, the length that adjustable knife bar stretches out, due to the elastic force of the existing vertical direction of set torsion spring, also there is the elastic force of horizontal direction, therefore, torsion can be fixed and rotate hex nut, making hex nut power when screwing and screw out be all fixing, effectively ensure that the stressed of nut, in order to avoid impaired fast.
Description
Technical field
The utility model relates to a kind of hex-head nut spanner, belongs to hardware & tools technical field.
Background technology
Generally be common spanner in present spanner, its force size depends mainly on staff.This kind of spanner is owing to determining force section, and when frequent torque nut, the edge of nut becomes round, ultimate failure gradually.
Utility model content
The utility model provides a kind of hex-head nut spanner, and its structure is simple, and easy to operate, lightweight, cost is low.
For solving above technical problem, the utility model provides following technical scheme: a kind of hex-head nut spanner, it is characterized in that, comprise plastic shell, inner casing, plastic cover, knife bar, sleeve, jump ring, pinion stand, gear, torsion spring and plug screw, described plastic shell entirety becomes T-shaped, the first half is semielliptical shape, built-in for bolted screwed hole, and integral central place has the cavity for installing inner casing; Described jump ring, pinion stand, gear, torsion spring are set in knife bar successively, and are completely installed in inner casing; Spacing by jump ring bottom pinion stand; Inner casing is installed in plastic shell, and knife bar stretches out plastic shell; Plug screw connects inner casing, and plastic shell top connects plastic cover; Described knife bar stretches out around plastic housing portion and is provided with sleeve, and the shape of cross section of knife bar is hexagon, and the internal face of sleeve is hexagon cylinder, and the outside wall surface of sleeve is fixedly connected with bottom plastic casing; Pad is provided with bottom described jump ring.
This hex-head nut spanner that the utility model relates to, structure is simple, the length that adjustable knife bar stretches out, due to the elastic force of the existing vertical direction of set torsion spring, also there is the elastic force of horizontal direction, therefore, torsion can be fixed and rotate hex nut, making hex nut power when screwing and screw out be all fixing, effectively ensure that the stressed of nut, in order to avoid impaired fast.
Accompanying drawing explanation
Fig. 1 is the utility model hex-head nut spanner Split type structure schematic diagram;
Fig. 2 is structure chart after the utility model hex-head nut spanner plastic shell and sleeve assemble.
Detailed description of the invention
As shown in Figure 1-2, spanner mainly comprises plastic shell 1, inner casing 12, plastic cover 3, knife bar 6, jump ring 7, pinion stand 8, gear 9, torsion spring 10 and plug screw 11, plastic casing and inner casing form main body, jump ring 7, pinion stand 8, gear 9, torsion spring 10 are set in knife bar 6 successively, and are completely installed in inner casing 12, have pad 5 bottom jump ring, plug screw 11 directly screws in interior faucal, inner casing is installed in plastic shell 1, adjustment moment of torsion, last installing sleeve 2 and at plastic cover top paste labels 4.
Pinion stand 8 is directly installed on spanner knife bar 6, and spacing with jump ring 7, utilizes torsion spring 10 to carry out the size of control torque.Detailed description of the invention described in the utility model does not form the restriction to the application's scope; within every spirit in the utility model design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection domain of the present utility model.
