Description
Technical field
The present invention is relevant with torque spanner structure, refers to that especially a kind of torque spanner is provided with first pointer and second pointer cooperates indication mechanism and numerical value spare to set torsion numerical value, and this spanner structure has scale setting and two kinds of modes of setting torsion of electronics sensing.
Background technology
The torque spanner structure of prior art; Like U.S. Pat 7703357B1; This patent name: the swing handle structure of torsion setting spanner; Comprise: a kind of swing handle structure of torsion setting spanner, this torsion setting spanner include a tool effect inserted terminal ratchet drives portion, an effort handle, a torsion adjusting lever, can be by the swing handle of original position turn and a torsion setting pointer; It is characterized in that: it mainly is in effort handle proximal end place; Cooperate a locking part and in advance locking the one hollow collar is arranged; And be provided with an inner circular tooth again adjacent to a side of swing handle in this collar level formula endoporus; Be combined with the outer shroud tooth simultaneously, make the inner and outer rings tooth of the collar and swing handle become the engagement card of normality to end state; Therefore; When desire adjustment torque value, only must swing handle be pressed to collar direction and make the disengaging of inner and outer rings tooth, just be able to the turn swing handle to drive the torsion adjusting lever of torque value set mechanism; Reach the adjustment effectiveness of expection; Treat that adjustment accomplishes, then only must remove elastomeric self elastic force of external force and mat, make the engagement card of inner and outer rings tooth reversion normality end state automatically.
But the fault of construction of this patent is:
When driving torsion adjusting lever (24) rotation when turn swing handle (25); This torsion setting pointer (26) is rotation together and then; Then cooperate the graduation apparatus (33) that is positioned at the next door with the interpretation torque settings; But be down scale contrast interpretation between this torsion setting pointer (26) and graduation apparatus (33), and the mode that reads needs people oneself to remove to judge the two relative position, when the user operates in rather dark working environment; Or the dysphotia of user own, the mode of this kind pointer and scale interpretation torsion numerical values recited has just not too made things convenient for.
The torque spanner structure of another patent and for example; Like U.S. Patent number US7685889B2, this patent name: digital torque force measuring tool, a kind of digital torque force measuring tool; It comprises a body; This body is provided with a drive division, the whole body portion, reaches a grip part, and wherein: this drive division is provided with a driving head, and this body reaches expection operation effect by the action of driving head; This grip part is made as suitable length, the usefulness that grips for the user; This body portion is provided with an accommodating unit, and this accommodating unit supplies the ccontaining usefulness of an electronic mechanism, is provided with at least one accommodation space in this electronic mechanism, is provided with double layer circuit unit at least in this accommodation space, and this circuit unit utilizes mode one on top of another to install; Circuit unit laminated construction reduced volume by this electronic mechanism reaches the effect of effectively utilizing accommodating unit, and this electronic mechanism also utilizes the laminated construction of circuit unit, increases the circuit unit that can install, to reach multi-functional effect.
The advantage of this patent is to improve the defective of the above-mentioned U.S. Pat 7703357B1 that quotes by own reading numerical values; This electronic mechanism (5) is for can provide clear and definite torque of wrenches numerical values recited; Generally speaking be provided with circuit board in this electronic mechanism (5); Circuit board can demonstrate digital numerical value and person more easy to use reads, and the screen that electronic mechanism (5) demonstrates torsion numerical value has light source and makes the user more clearly understand.
But the defective of this patent structure is: this electronic mechanism (5) need have battery electric energy as a whole to show and have digital torsion numerical value; And the electric energy in electronic mechanism (5) exhausts; And working environment is immediately under the situation of electric energy supplement or battery; As go out to repair each machinery or when going out to repair, electronic mechanism (5) promptly can be because of promptly showing torque value under the no battery status again, torque spanner structure only can work as general spanner use and do not had the effect of measurement torque value.
Summary of the invention
The problem that the invention desire solves: a kind of torque spanner structure is provided with first pointer, this first pointer displacement with the displacement of adjustment group, and indication mechanism is promptly known its torque value.
The technological means of dealing with problems: a kind of torque spanner structure comprises:
