Abstract

The invention relates to a torque opener structure. A main body mainly comprises a holding part, an action part and a setting part; the holding part comprises a grab handle and an elastic element; the elastic element is arranged inside the grab handle; the grab handle is provided with a through-hole; the action part passes through the grab handle, and one end of the action part passes through and is pushed against the elastic element; the action part is provided with a display rod which passes through the through-hole; the setting part is arranged in the grab handle, and one end of the setting part pushes against the action part; the setting part is provided with a rotating element and an adjustment cover; and the adjustment cover can drive the rotating element to rotationally shift. Therefore, the adjustment cover is rotated to enable the setting part to push against the action part, and the pressure of the action part on the elastic element is changed. The display rod of the action part can make equal shift so as to display the threshold value of current torque force. The torque opener structure can definitely display the maximum threshold value of currently set torque so as to adjust torque threshold value quickly and provide bolt arrangement operation required by different torque.

Description

Torsion screwdriver structure

Technical field

The present invention relates to a kind of torsion screwdriver structure.

Background technology

See also No. 095213081 " deciding torsion screwdriver " patent of TaiWan, China number of patent application, this bottle opener body comprises that mainly a lever, a torsion assembly, lead device, a stop part and a capping, this torsion assembly includes an elastomer and a slide block, wherein this elastomer correspondence is placed in the appearance group space of lever, in addition, slide block week, side was formed with the guide rail of the guide groove of corresponding lever, but so that slide block just the contraposition slide guide is in the appearance group space of lever, and block is in elastomer; This is led device and comprises and lead a moving part and a drive rod, wherein this drive rod with lead moving part and be set as one for relative group, this drive rod one end is formed with drive end, drive end is the hole that connects of the perforation, torsion assembly and the lever that are extended through slide block in regular turn, and lead the face that pushed away of leading the face of pushing away that moving part is provided with corresponding slide block, and be provided with the location division in drive rod and the opposing end surface of leading portion; Whereby, rotating capping can make bottle opener do the setting of torque value.

Above-mentioned " deciding torsion screwdriver ", though it has the effect that the bottle opener torque value is set, but this bottle opener there is no method on the setting torque value shows present torque value boundary, therefore can't allow operator one order Liao so learn torque settings, when each the application, must reset capping and rotate the number of turns, therefore quite inconvenient in the use; And should decide torsion screwdriver only capping one end have torsion and adjust effect, its torsion adjustment effect can not reach optimum efficiency.

Summary of the invention

Technical problem underlying to be solved by this invention is, overcome the above-mentioned defective that prior art exists, and a kind of torsion screwdriver structure is provided, it can clearly show present setting torsion maximum figure value, can adjust the torsion boundary value rapidly whereby, establish operation with the bolt that different torsion demands are provided.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of torsion screwdriver structure is characterized in that, body mainly comprises a grip part, a service portion and a configuration part, wherein; There are a lever and an elastic component in this grip part, and this elastic component is located in the lever and this lever has a through hole; This service portion is arranged in the lever and an end is worn to elastic component, and this service portion has a display pole break-through in through hole; This configuration part is located in the lever and an end is replaced service portion, and this configuration part has one to change part and and adjust lid, and this adjustments lid can drive the displacement that rotates of commentaries on classics part; Whereby, rotate the adjustment lid and make configuration part pushing and pressing service portion change pressure to elastic component, the display pole of this service portion also can be done equal displacement and show present torsion boundary value.

Aforesaid torsion screwdriver structure, wherein bar is driven in the configuration part, and this drives bar one end and is fixedly arranged on and adjusts lid and shaft break-through in changeing part, cover this by pulling adjustment and drives bar and can do chimericly with changeing part, rotates to adjust again and cover this and drive bar and can drive the commentaries on classics part and carry out spiral shell and move.

Aforesaid torsion screwdriver structure, its transfer part has a groove surface, and this drives bar a bumping surface.

Aforesaid torsion screwdriver structure, wherein there is an adjustable block piece grip part, and this block piece and elastic component are replaced, and tool is adjusted the effect of torsion boundary value.

Aforesaid torsion screwdriver structure, wherein service portion has a bull stick and a rachet, and this bull stick can be beated with the rachet ratching.

Aforesaid torsion screwdriver structure, wherein driving bar has an end to be connected to service portion.

Aforesaid torsion screwdriver structure, wherein groove surface has several grooves, and this bumping surface has several pieces.

Aforesaid torsion screwdriver structure, wherein block piece has a bolt face, and this bolt face action can make block piece do the moving adjustment of spiral shell in lever.

Whereby, when desire is set the torsion boundary value, only need spur and adjust the lid rotation, this configuration part promptly can induced effect portion change being stressed of elastic component, this display pole position also can be equal to change with operating member, can clearly be found out by display pole by the torsion boundary value that the induction of elastic component and display pole relativity is changed; But and set up spiral shell at the lever front end and move the block piece of adjusting, this block piece and elastic component are replaced, and the effect of tool adjustment torsion boundary value, and torsion screwdriver structure of the present invention whereby can be adjusted torsion boundary maximum by both sides, and the effect of the dual adjustment of tool, to reach the adjusting of torque value maximum magnitude.

The present invention is when changing the torque value boundary value, adjusting lid by pulling makes the inner structure of setting end chimeric mutually, adjusting lid adjustment inner space size in rotation is discharged or compression elastic piece, being subjected to different elastic force to compress the ratchet that produces different torsion by the effect end again beats, reaches the setting of different torque values; The present invention not only can be found out the setting of torque value by lever, when the adjustment lid is return original position, can do the location with lever and rotate, the property smoothly when more promoting the torsion screwdriver rotation whereby.
