Description

A kind of mechanical type bolt clipper

The utility model relates to a kind of tools production, relates more specifically to a kind of mechanical type bolt clipper.

At present traditional bolt clipper is commonly called as " locking pliers ", use lever principle and make, not only volume big, carry inconvenience, and Heavy Weight, operation is effort very.

The purpose of this utility model is to provide a kind of mechanical type bolt clipper, and application lever, cam, speed change principle of combining are carried out ingenious design, the purpose that reached in light weight, volume is little, operation is very laborsaving.

The purpose of this utility model is achieved in that a kind of mechanical type bolt clipper, form by cutter head, pressing plate, circular shaft, handle, upper and lower clamping plate, be equipped with fixed rotating shaft, handle pin, arm pivot post, left and right axle nail, locking spanner between the upper and lower clamping plate, the lower end of quiet cutter head is connected with fixed rotating shaft, and the upper end of static handle is connected with handle pin; It is characterized in that: the upper right side of fanned tooth board is established a rotating shaft and is connected with the lower end of dynamic cutter head, rotating shaft places on the arc board slot of lower plate, fanned tooth board is provided with the slotted eye identical with board slot, fixed rotating shaft is placed in one, a straight pin is established at the left end back side of fanned tooth board, and put an extension spring between the steady pin on the lower plate, the upper end of fixed handle is provided with the eccentric shaft seat board, and be connected with arm pivot post, roller bearing places on the eccentric shaft seat board, its outer propelling tooth plate that is equipped with, advance the right side of tooth plate to put a small extension spring, make the gear interlock of itself and fanned tooth board lower edge, put a torsion spring on the right centerpin, make coaxial supporting tooth block block fanned tooth board clockwise.

The utility model modern design, handsome in appearance, time saving and energy saving, easy to carry is a new generation product of realizing the steel wire rod cutting.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model outward appearance front view.

Among the figure:

1 quiet cutter head 2 dynamic cutter heads 3 pressing plates 4 circular shafts

5 train wheel bridges, 6 lower plates, 7 fixed rotating shafts, 8 handle pins

9 arm pivot posts, 10 left side axle nails, 11 right centerpins, 12 locking spanners

13 static handles, 14 fanned tooth boards, 15 rotating shafts, 16 slotted eyes

17 straight pins, 18 steady pins, 19 extension springs, 20 fixed handles

21 eccentric shaft seat boards, 22 roller bearings 23 advance tooth plate

24 small extension springs, 25 torsion springs, 26 supporting tooth blocks, 27 board slots

As shown in Figure 1 and Figure 2: quiet cutter head 1 of the present utility model and dynamic cutter head 2, by circular shaft 4, be fixed between two block pressur plates 3, upper and lower clamping plate 5,6 and between be equipped with fixed rotating shaft 7, handle pin 8, arm pivot post 9, left and right axle nail 10,11, locking spanner 12, the lower end of quiet cutter head 1 is connected with fixed rotating shaft 7, the upper end of static handle 13 is connected with handle pin 8, and the left and right axle nail 10,11 of upper and lower clamping plate 5,6 usefulness is fixed.

As shown in Figure 1, the upper right side of fanned tooth board 14 is established a rotating shaft 15 and is connected with the lower end of dynamic cutter head 2, rotating shaft 15 places on the arc board slot 27 of lower plate 6, fanned tooth board 14 is provided with the slotted eye 16 identical with board slot 27, fixed rotating shaft 7 is placed in one, a straight pin 17 is established at the left end back side of fanned tooth board 14, and put an extension spring 19 between the steady pin on the lower plate 6 18, the upper end of fixed handle 20 is provided with eccentric shaft seat board 21, and be connected with arm pivot post 9, roller bearing 22 places on the eccentric shaft seat board 21, its outer being equipped with advances tooth plate 23, advances the right side of tooth plate 23 to put a small extension spring 24, makes the gear interlock of itself and fanned tooth board 14 lower edges, put a torsion spring 25 on the right centerpin 11, make coaxial supporting tooth block 26 block fanned tooth board 14 clockwise.

The course of work of the present utility model is such:

One, to lock spanner 12 rotates, fixed handle 20 can be swung, when fixed handle 20 is put to the right to the top, fixed handle 20 promotes supporting tooth block 26 afterbodys, and overcome the torsion of torsion spring 25, the head and the fanned tooth board 14 of supporting tooth block 26 are thrown off, advance this moment tooth plate 23 also to be out of gear with the lower edge of fanned tooth board 14, because the pulling force effect of extension spring 19, the arc-shaped slot 16 of fanned tooth board 14 slides to the right along fixed rotating shaft 7, the rotating shaft 15 of dynamic cutter head 2 lower ends is under fanned tooth board 14 drives, also slide to the right along the board slot 27 of lower plate 6, with the lower end of quiet cutter head 1 mutually also, the edge of a knife of dynamic cutter head 2 and quiet cutter head 1 is opened to ultimate range.

Two, will be placed between the edge of a knife by the broken string material, fixed handle 20 is swing left firmly, this moment the eccentric shaft seat board 21 on the fixed handle 20, according to the cam principle, by roller bearing 22, to advance tooth plate 23 to advance a tooth left, simultaneously by advancing the gear interlock of tooth plate 23 and fanned tooth board 14, fanned tooth board 14 is advanced a tooth left, supporting tooth block 26 has blocked the route of retreat to the right of fanned tooth board 14, left under the drive that fanned tooth board 14 advances under the effect of its torsion spring 25 at this moment, quiet cutter head 1 begins to open with the lower end of dynamic cutter head 2, and then the edge of a knife is implemented the cutting to wire rod.

Three, the swing that moves in circles of fixed handle 20, and the afterbody that does not collide supporting tooth block 26 to the right when swinging serves as effectively, swing so each time all makes fanned tooth board 14 move teeth clockwise, and it is more and more littler that cutter head is dehisced, until wire rod is cut off.

Four, instrument is finished using, fixed handle 20 can put left to static handle 13 near the place, will lock the spanner rotation then, make fixed handle 20 locked, be easy to carry.

The utility model is a telescopic handle, to super-huge wire rod cutting, can utilize lever principle, becomes more laborsaving and convenient.
