Abstract

The utility model relates to a trowel structure improvement, in particular to a trowel structure improvement capable of providing angle adjustment of a trowel plate and a trowel handle, wherein the trowel structure improvement is mainly characterized in that the trowel plate is combined with a pressing plate; a polygonal shaft rod is upward formed by the pressing plate in the longitudinal direction; a spiral connecting part is formed at the bottom end of the shaft rod so as to lead the spiral connecting piece to penetrate from a stepped vent hole of the trowel handle and to be locked on the spiral connecting part of the shaft rod of the pressing plate so as to pivot the trowel handle on the trowel plate, while the stepped vent hole of the trowel handle is internally and fixedly provided with a positioning piece which is used for leading a positioning part of a limiting piece of a positioning device to be sheathed and limited; the top end of the limiting piece is fixedly provided with a pressing part; by being pressed, the pressing part is linked with the limiting piece and an elastic element so as to lead the limiting piece to move downward and lead the limiting part of the limiting piece to be separated and limited with the positioning piece; and the trowel handle and the trowel plate can take on angle transformation by rotating the trowel handle.

Description

The trowel structural improvement

Technical field

The new case of this practicality is a kind of trowel structural improvement, refers to a kind of trowel structural improvement that knife plate and handle angle adjustment are provided especially.

Background technology

Press, the structure of general trowel, roughly be fixing a handle on the knife plate, and this handle and knife plate are the secure bond state, the meaning i.e. angle of this handle and knife plate is fixed, make handle and knife plate present the setting of parallel shape, and in the workplace, may be because of the restriction of position or constructor's needs, and when needing to change the angle that grips and being beneficial to construct, this trowel also can't satisfy constructor's demand, and then causes the unclear of efficiency of construction.

The utility model content

Edge this, the creator of this case is engaged in the design and the manufacturing experience for many years of various hardware ﹠ toolss based on it, especially in the inking of architectural hardware instrument, in view of the inconvenience of existing trowel on using, phase with provide a kind of can simple and easy adjustment knife plate and the angle of handle, to satisfy constructor's demand, actively studied improvement, via test and change repeatedly, get generation of the present utility model eventually.

That is, the main purpose of the utility model is to be to set a position device by the shaft rod upper sleeve of knife plate, and cooperates the keeper in the handle axis hole, and adjusted and locate the angulation of knife plate and handle, is beneficial to the constructor on demand and the trowel structural improvement of adjustment.

In order to achieve the above object, the new case of this practicality mainly is in conjunction with a pressing plate on a cutter metal plate, this pressing plate is moulding one polygonal axostylus axostyle up vertically, the bottom of this axostylus axostyle is moulding one spiral shell knot portion then, for penetrating and be locked in the spiral shell knot portion of pressing plate axostylus axostyle in class's open-work of spiral shell knot part by handle, tie this handle on knife plate with pivot, and in class's open-work of handle, set firmly positioning piece, this keeper is spacing for the location division noose of the locating part of positioner, the top of this locating part then sets firmly a press section, by pushing this press section, make this locating part of press section interlock and flexible member, and locating part is able to toward bottom offset, and the limiting section that makes this locating part and keeper break away from spacingly, rotates the trowel structural improvement that handle can make handle and knife plate angle presentation change.

The beneficial effects of the utility model are: be to be to set a position device by the shaft rod upper sleeve of knife plate, and cooperate the keeper in the handle axis hole, and adjusted and locate the angulation of knife plate and handle, be beneficial to the constructor on demand and the trowel structural improvement of adjustment

The joint embodiment

See also Fig. 1～shown in Figure 3, wherein, the new case of this practicality mainly is to include a knife plate 1, a handle 2 and a location device 3, wherein:

One cutter metal plate 1 is thereon in conjunction with a pressing plate 11, and this pressing plate 11 is moulding one polygonal axostylus axostyle 12 up vertically, and the bottom of this axostylus axostyle 12 is moulding one spiral shell knot portion 121 then;

One handle 2, it is the one class's open-work 21 of moulding thereon, in this class's open-work 21, set firmly positioning piece 22, the internal diameter 221 of this keeper 22 is to be the polygonal setting, and this handle 2 is by penetrating and be locked in the spiral shell knot portion 121 of pressing plate 11 axostylus axostyles 12 in class's open-work 21 of spiral shell knot part 23 by handle 2, tying this handle 2 on knife plate 1 with pivot;

One location device 3, be to be located in class's open-work 21 of handle 2, it mainly is to comprise a flexible member 31 and a locating part 32 that is sheathed on the axostylus axostyle 12, the bottom moulding one of this locating part 32 is polygonal location division 321, and the central axis of this locating part 32 presents the polygonal axis hole 322 similar with axostylus axostyle 12 outer shape, and the top of this locating part 32 then sets firmly a press section 33;

Person in this way, spiral shell is tied in the spiral shell knot portion 121 that penetrates and be locked on pressing plate 11 axostylus axostyles 12 in class's open-work 21 of element 23 by handle 2, tie this handle 2 on knife plate 1 with pivot, again this flexible member and locating part 32 are sheathed on the axostylus axostyle 12, and make the polygonal of axostylus axostyle 12 external diameters and the polygonal axis hole 322 of locating part 32 be spacing shape, and make this locating part 32 be presented, bottom offset, noose is fixed this press section 33 in the top of locating part 32 again, so, this locating part 32 be subjected to flexible member 32 contact and toward top offset (this moment locating part 32 axis holes 322 be subjected to the spacing of axostylus axostyle 12 external diameters, only can present, the bottom offset shape), and be resisted against in the internal diameter 221 of keeper 22, and the limiting section 321 that makes locating part 32 to be able to clip spacing in the internal diameter 221 of keeper 22, and then make handle 21 to locate with knife plate 1, make the constructor be able to hand grip 21, can this knife plate 1 of interlock and construct, and when constructor's desire is adjusted the angle that handle 2 and knife plate 1 be, as Fig. 4～shown in Figure 6, push this press section 33, make this locating part 32 of press section 33 interlocks and flexible member 31, and locating part 32 is able to toward bottom offset, and make the limiting section 321 of this locating part 32 and keeper 22 break away from spacing, rotation handle 21 can make the conversion of handle 21 and knife plate 1 angle presentation, to meet constructor's demand, during to the precalculated position, decontrol this press section 33, start by flexible member 31, and press section 33 and locating part 32 are able to toward top offset, and the limiting section 321 that makes locating part 32 to be able to clip spacing in the internal diameter of keeper 22, can finish the location of the conversion of angle and handle 21 and knife plate 1.

Above-mentioned the utility model only illustrates with most preferred embodiment, to being familiar with the personnel of this technology, changes enforcement when carrying out each, and only this variation is implemented, and all should be included in spirit of the present utility model and the category.

In sum, the utility model is by pushing this press section, make this locating part of press section interlock and flexible member, and locating part is able to toward bottom offset, and make the limiting section of this locating part and keeper break away from spacing, rotate handle and can make handle and the conversion of knife plate angle presentation, no matter it is structural change, or be the enhancement on the effect, unquestionable all, and the utility model does not see publication, also unexposed use before application, met the patent application condition in fact, so propose patent application in accordance with the law.
