Description

Safe buckle of iron scissors tool

Technical field

The utility model has about a kind of safe buckle of iron scissors tool, is in details of the words a kind of on-slip ring being provided with an increase friction effect in its switch position of tinsmith snips, to extend the service life of safety buckle.

Background technology

Generally traditional tinsmith snips consist predominantly of the cutting edge that two-phase is pivoted, blade and grip part is formed respectively in the two ends of two cutting edges, user so can be allowed with one hand to divide the grip part of holding two cutting edges, and control the folding of tinsmith snips, and then carry out the work packages such as cutting iron sheet, to reach its predetermined work object.

Refer to TaiWan, China letters patent book number M424227 " tin snip safety device ", comprise one and there is the handle that two blades and two that can interlock shearing operate two blades execution shear action, and determine in tinsmith snips arrangement one safety device that two blades must not open, this safety device comprises: the protuberance, at an edge of outstanding two handles is absorbed in the aforementioned recess with the handle edge of protuberance, and the buckling piece that is connected to an another handle; This buckling piece comprises the movable part, that two rotations cover the two handle places of drawing close can rotate beyond along with movable part the blocking part that protuberance snaps in recess between two movable parts, and one is linked to prevention portion between two movable parts and blocking part.

Previous security devices can under tinsmith snips clamping state, in a wherein handle pivot pendulum hook in another handle, make tinsmith snips by spring affects normality present clamping and receives effect; But, existing safety device is arranged at the short column of inner face to be forced into mode by two, safety device is made to be hubbed at a wherein handle to cover kenel, but safety device is only be pivoted by two short columns with the handle be pivoted, after the long-term pivot pendulum of safety device uses, easily because surface abrasion causes safety device and handle to lose the effect of false location, when user is when operating tinsmith snips, safety device easily produces improper rocking and affects operation.

In view of this, inventor of the present utility model relies on the development Experience being engaged in related industry for many years, for existing tinsmith snips institute problems faced further investigated, and actively seek solution, through the research and development of long-term endeavour, finally successfully create a kind of safe buckle of iron scissors tool, it is a kind of on-slip ring being provided with an increase friction effect in its switch position of tinsmith snips, to extend the service life of safety buckle.

Utility model content

The utility model has about a kind of safe buckle of iron scissors tool, and it is a kind of on-slip ring being provided with an increase friction effect in its switch position of tinsmith snips, to extend the service life of safety buckle.

For reaching aforementioned creation object, the utility model provides a kind of safe buckle of iron scissors tool, include one first caliper, one second caliper and a safety buckle, wherein, the two ends of this first caliper and the second caliper are formed with a lever section and a blade section respectively, and this first caliper and the second caliper are in lever section and the intersegmental section of being pivoted respectively being formed with confession setting interlaced with each other of blade, this first caliper is formed with a perforation be pivoted for safety buckle in lever section nearly inner edge place, this second caliper is formed with a fastener in lever section inner edge place;

This safety buckle includes a fastener body, a shank of bolt and an on-slip ring, this fastener body has the side plate that two are covered in the first caliper two side perforation, and the corresponding punch position of this biside plate is respectively formed with a lock apertured, this fastener body inside contracts in the corresponding punch position of wherein side plate inner face and is formed with an interlayer arranged for on-slip ring, this shank of bolt is synchronously through on-slip ring, perforation and lock apertured, and fastener body is hubbed at the first caliper, this fastener body is formed with one between biside plate can be placed in the connecting rod of fastener by movable button.

So, by the mode of shank of bolt in conjunction with fastener body and the first caliper, the tightness that can bolt lever lock be relied on to establish makes to obtain a false locating effect between safety buckle and the first caliper, and this on-slip ring effectively can increase the coefficient of friction between safety buckle and the first caliper, make both false locating effects more obvious.

Aforementioned fastener body is respectively formed with a fin in biside plate surface.

Aforementioned fastener is formed with in end face the oblique surface that a guiding connecting rod is convenient to slide fastener.

From aforementioned author content, the utility model " safe buckle of iron scissors tool " relatively existing tin snip safety device is only planted with alignment pin, adopt the bolt lever lock side of establishing to establish as engagement means, therefore having adjustable lock establishes degree to affect in conjunction with degree of tightness, and more have additional the on-slip ring of coefficient of friction between a lifting fastener body and the first caliper, durable false locating effect can be obtained, under making fastener body Long-Time Service, still not easily produce loosening situation; Therefore the utility model can say it is that one quite has practicality and creationary creation, is quite worth industrial circle to be promoted, and makes society know.
