Abstract

The utility model discloses a pair of adjustable pneumatic shears, which comprises a housing, wherein an opening is formed in the upper end of the housing; a pair of lug arms is arranged at the opening and is pivotally connected with a shears body through a pivot; an air inlet connector is arranged at the lower end of the housing; an air valve switch is arranged on the housing and actuated through a pressing piece; a sliding plug is arranged in the housing; the front end of the sliding plug is connected with a pair of inner ends of the shears body; a spring is arranged between the exterior of the sliding plug and the interior of the housing; a screw hole is formed in the lower end of the housing; a bolt is screwed in the screw hole; the bottom surface of the sliding plug is additionally sleeved with a hard object, so that the sliding plug is propped against the bolt through the hard object; when the bolt is rotated, the sliding plug is driven by the bolt to move forwards and backwards, so that a tapered groove in the front end of the sliding plug is changed relative to the open angle of the inner ends of the shears body, and then the angle between a pair of outer ends of the shears body is changed accordingly. Therefore, the adjustable pneumatic shears can be used for shearing objects with different calibers, and the property of seizing objects to be sheared is improved during shearing.

Description

Adjustable pneumatic is cut

Technical field

The utility model relates to a kind of pneumatic scissors, particularly a kind of pneumatic clipper of adjustable shear openings of sizes.

Background technology

Existing pneumatic scissors, there is a housing, the upper end of housing is an opening, opening is provided with a pair of ear arm with pivot pivot joint one scissor body, the lower end of housing is provided with an inlet suction port, and be provided with an air valve switch in housing, air valve switch is by pressing tablet institute start, be provided with a sliding plug in housing, with the front end of this sliding plug and a pair of the inner of scissor body, join, and outside this sliding plug and between in housing, a spring is arranged, when pressing tablet is pressed, start air valve switch, import gas to housing by inlet suction port, gas is through the outlet of a fixed block, and then promotion sliding plug, make a cone groove of sliding plug front end relatively make the interior end opening in scissor body, along with the outer little folding angle of imperial palace of cone groove, diminish, and then allow the opening of a pair of outer end of scissor body also diminish thereupon, to produce the action of shearing, because the object be sheared is mainly metal wire etc., different thicknesses is arranged, while removing to cut the small diameter metal line with large opening at every turn, the slippage of shearing, metal wire is not easy to fix.

The utility model content

Main purpose of the present utility model is to provide a kind of adjustable pneumatic to cut, and can produce the angle kerve of different folding angles, and more convenient shearing work becomes the pneumatic clipper of the different bores of adjustable shear, improves while shearing being cut the interlock of thing.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

A kind of adjustable pneumatic is cut, there is a housing, the upper end of housing is an opening, opening is provided with a pair of ear arm with pivot pivot joint one scissor body, the lower end of housing is provided with an inlet suction port, and be provided with an air valve switch in housing, air valve switch is by pressing tablet institute start, be provided with a sliding plug in housing, with the front end of this sliding plug and a pair of the inner of scissor body, join, and outside this sliding plug and between in housing, a spring is arranged, be provided with a screw in the lower end of housing, screw is installed with a bolt, another cover one adamant that adds in the bottom surface of sliding plug, allow sliding plug push up mutually with adamant and bolt, work as rotating bolt, allowing bolt drive sliding plug through adamant moves forward and backward, make a cone groove of sliding plug front end relatively make the inner folding Angulation changes in scissor body, and then allow scissor body a pair of outer end angle also thereby change.

For making your juror can further understand the utility model, be to reach technology, means and the effect that predetermined purpose is taked, hereby for a better feasible embodiment, and coordinate graphic being described in detail as follows, believe the purpose of this utility model, feature & benefits, when obtaining thus one deeply and concrete understanding.

The specific embodiment

As shown in Fig. 1 to 7, for a kind of adjustable pneumatic of the utility model is cut, there is a housing 1, the upper end of housing 1 is an opening 11, opening 11 is provided with a pair of ear arm 12 with pivot 12 pivot joint one scissor bodies 2, the lower end of housing 1 is provided with an inlet suction port 13, and be provided with an air valve switch 14 in housing 1, air valve switch 14 is by 15 starts of a pressing tablet, be provided with a sliding plug 16 in housing 1, front end one cone groove 17 with this sliding plug 16 joins with a pair of inner 21 of scissor body 2, and between in this sliding plug 16 and housing 1, a spring 18 is arranged, be provided with a screw 31 in the lower end of housing 1, screw 31 is installed with a bolt 32, another cover one adamant 40 that adds in the bottom surface of sliding plug 16, because sliding plug 16 can be plastic plastotype part, if be added with the external member of the metal-made (iron) of adamant 40, just can allow sliding plug 16 push up mutually with adamant 40 and bolt 32, and because of the screw of bolt 32 through the fixed block 19 in housing 1 back segment opening part, when as shown in Figure 4, while locating with the outer end of die nut 33 rotating bolts 32, allow the inner drive sliding plug 16 of bolt 32 move forward and backward, the cone groove of sliding plug 16 front ends is made relatively in the inner of scissor body 2 21 folding Angulation changes, as a pair of outer end 22 angles of cutter hub 2 fade to angle b by a, and then allow scissor body 2 a pair of outer end 22 angles also thereby change, become the pneumatic clipper of adjustable shear different thicknesses bore, improve while shearing being cut the interlock of thing.As Fig. 7, when pivot 10 wherein is removable, in figure, be the combination of screw and nut, substitute different scissor bodies 2 to facilitate, the length of its blade or outer end all has different persons.As Fig. 5 to 6, one for before start, one for after start, when pressing tablet 15 is pressed toward moving down, just start air valve switch 14, import gas to housing 1 by inlet suction port 13, gas is through the venthole of the fixed block 19 in housing 1 back segment, and then promotion sliding plug 16, make a cone groove 17 of sliding plug 16 front ends because of past reach, relatively make in the inner of scissor body 2 21 openings, along with the cone little folding angle of the outer imperial palace of groove 17, diminish, and then allow the opening of a pair of outer end 22 of scissor body 2 also by diminish greatly thereupon, shear to produce the action that this quilt is cut thing 4, afterwards by spring 18 by sliding plug 16 pushed home.

Structure in sum, the utility model uses the bolt of the adjustment use of particular design, allow it advance and retreat, change the inside and outside openings of sizes of scissor body thereupon, allow scissor body 2 can be easy to clasp and live the line body or cut thing, cut off very accurately, not at random slippage, allow action accurately, and the structure of its increase allows the people the most easily understand and implements, so good usability and convenience can be provided, it is a complete and existing different mechanism.

The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by the described protection domain with claim.
