Abstract

The utility model discloses a pair of improved rotating shearing and holding shears which comprise a fixed handle and a movable handle, wherein the fixed handle and the movable handle are connected together in a hinged mode. A reset spring is installed between the two handles, a dividing rotating knife wheel is installed at the position, above a hinged shaft, of the fixed handle, the end of a rotating knife wheel shaft horizontally extending to the outer side of the hinged shaft is connected with two shears blades through a horizontal pin roll, the rotating knife wheel shaft between the pin roll and the rotating knife wheel is sleeved with a sliding block in a sliding fit mode, an annular groove is formed in the sliding block, the upper end of the front portion of the sliding block and the lower end of the front portion of the sliding block are respectively provided with a draw hook, the two draw hooks extend into notches in flanges of the two shears blades respectively, the shears blades are made to perform open and close movement, the two ends of the hinged shaft are fixedly and respectively connected with a shifting fork, and the upper ends of the shifting forks extend into the annular groove of the sliding block. The improved rotating shearing and holding shears are simple in structure and can be used for shearing objects horizontally, the wrist does not need to be turned or twisted, and therefore the improved rotating shearing and holding shears are convenient to use.

Description

Modified rotary cutting is taken and is cut

Technical field

The utility model belongs to the improvement of scissor construction, and particularly modified rotary cutting is taken and cut.

Background technology

Existing scissors, in use, its cutting edge body and handle are generally all positioned at same perpendicular, the article that this places for level of shear, use is convenient.But for the pruning of the article of vertical placement, such as shrub or branch, flower arrangement etc., often to reverse wrist, make cutting edge body can keep level, just can finish the work.Work of a specified duration, wrist is easy to fatigue, and arm also can be very tired, uses very inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of modified rotary cutting to take and cuts, and it is simple in structure, makes scissors can carry out horizontal shear article, and without turn-knob wrist, easy to use.

The purpose of this utility model is achieved in that a kind of modified rotary cutting is by cutting, comprise the fixed handle and the flexible handle that are hinged together, between two handles, back-moving spring is installed, a calibration rotor wheel is installed on the fixed handle of jointed shaft top, level extends its end of rotor wheel shaft in jointed shaft outside by articulated two shearing blades of horizontal bearing pin, on rotor wheel shaft between bearing pin and rotor wheel, be slidably matched and be set with a sliding shoe, on sliding shoe, there is an annular groove, the anterior upper and lower side of sliding shoe has respectively a drag hook, two drag hooks extend respectively in two gap on shearing blade flange, make shearing blade do open and close movement, jointed shaft two ends are affixed a shift fork respectively, shift fork upper end extends in sliding shoe annular groove.

When the utility model is used, palm is vertical state gripping handle, along with flexible handle rotates up and down around the jointed shaft on fixed handle, shift fork by jointed shaft two ends promotes sliding shoe and slides before and after rotor wheel shaft, then by sliding shoe front portion, be stuck in two drag hooks in shearing blade gap and order about shearing blade and do open and close movement; Rotation rotor wheel shaft can change the operating position of shearing blade, horizontal or vertical.Be able to shearing such as shrub, branch etc., and without turn-knob wrist, easy to use.The utility model novel and reasonable structure, cheap, be easy to promote.

Below in conjunction with accompanying drawing, the utility model is described in more detail.

Fig. 1 is main TV structure schematic diagram of the present utility model;

Fig. 2 is use status architecture schematic diagram of the present utility model.

Embodiment

A kind of modified rotary cutting is taken and is cut, as Fig. 1, shown in Fig. 2, comprise the fixed handle 2 and the flexible handle 13 that are hinged together, between two handles, back-moving spring 12 is installed, a calibration rotor wheel 4 is installed on the fixed handle 2 of jointed shaft top, level extends rotor wheel shaft 11 its ends in jointed shaft outside by articulated two shearing blades 7 of horizontal bearing pin 9, on rotor wheel shaft 11 between bearing pin 9 and rotor wheel 4, be slidably matched and be set with a sliding shoe 5, on sliding shoe 5, there is an annular groove, the anterior upper and lower side of sliding shoe 5 has respectively a drag hook 14, two drag hooks 14 extend respectively in two gap on shearing blade 7 flanges, make shearing blade do open and close movement, jointed shaft two ends are affixed a shift fork 10 respectively, shift fork 10 upper ends extend in sliding shoe 5 annular grooves.During use, along with flexible handle 13 rotates up and down around the jointed shaft on fixed handle 2, shift fork 10 by jointed shaft two ends promotes sliding shoes 5 and slides along rotor wheel shaft 11 front and back, then by sliding shoe 5 front portions, be stuck in two drag hooks 14 in shearing blade gap and order about shearing blade and do open and close movement; Rotation rotor wheel shaft 11 can change the operating position of shearing blade, horizontal or vertical.

As shown in Figure 1, spring holder 3 is installed in fixed handle 2, the detent arranging on this spring holder 3 and rotor wheel shaft 11 matches.Make rotor wheel shaft 11 can be able to calibration rotation, two adjacent operating positions differ 90 degree.Obviously, spring holder 3 can also be arranged in a side end face of rotor wheel 4, also can realize the calibration function of rotor wheel shaft 11.

As shown in Figure 1, as a kind of improvement of the present utility model, fixed handle 2 end horizontal of shearing blade 7 belows affixed a scissors folder 8, the central shaft of scissors folder 8 is vertically arranged, scissors presss from both sides in 8 both sides clamp outer rims a gap is being set respectively, pull bar 6 free ends that are hinged on both sides shift fork 10 extend respectively in said gap, order about scissors folder 8 and do horizontal open and close movement.Configuration scissors folder 8 is especially applicable to pruning grape branch, scissors folder 8 clamping grape branches, and shearing blade 7 is pruned, and a hand can carry out operation, and it is time saving and energy saving to use.

As shown in Figure 1 and Figure 2, the articulated screens bar 1 of fixed handle 2 ends, the lower end of screens bar 1 is stuck in the handle grooves of flexible handle 13 end belows.
