Abstract

The utility model discloses a power saving iron-sheet shear, which is mainly composed of a left and a right cutter head bodies, and a left and a right handle bodies, wherein the left cutter head body and the right handle body are connected into a whole, and the left and the right cutter head bodies are movably connected with each other by a cheek shaft screw bolt. The utility model is characterized in that the top end of the left handle body is movably connected with the right handle body by a connecting short shaft; the lower end of the right cutter head body is movably connected with the left handle body by the other short shaft; the top of the left handle body is clamped between the right cutter head body and the right handle body.

Description

Laborsaving tinsmith snips

Technical field

The utility model relates to the hardware ﹠ tools field, refers more particularly to tinsmith snips wherein.

Background technology

Tinsmith snips are a kind of hardware ﹠ tools, and it is widely used in being mainly used to shear iron sheet, stainless steel sheet| etc. in the every field and relevant industrial trade in the daily life.Tinsmith snips commonly used relatively simple for structure, mainly form by a pair of caliper, two calipers flexibly connect mutually by the cheek axle bolt of centre, and, usually the caliper more than the cheek axle bolt partly is called body of tool bit, the following caliper of cheek axle bolt partly is called handle body, and left and right two body of tool bit are provided with the cutting edge of interlock mutually; During use, the operator holds left and right two handle bodies earlier, opens body of tool bit, and iron sheet to be sheared is placed between two body of tool bit, firmly closes up two handle bodies then, makes two body of tool bit closures, just can reach the purpose of shearing.The shortcoming of the tinsmith snips of above-mentioned traditional structure is: when shearing iron sheet, the operator must apply bigger power, and operation is effort relatively.

Summary of the invention

At the problems referred to above, the utility model will provide relatively labour-saving tinsmith snips of a kind of shearing manipulation.

For achieving the above object, the technical solution adopted in the utility model is: described laborsaving tinsmith snips, mainly be made up of left and right body of tool bit and left and right handle body, wherein left body of tool bit and right handles body link into an integrated entity, and left body of tool bit and right body of tool bit flexibly connect mutually by cheek axle bolt; Be characterized in: the top of left handle body connects minor axis by one and the right handles body flexibly connects, and the lower end of right body of tool bit flexibly connects by another minor axis and left handle body, and the top of left handle body is clamped between right body of tool bit and the right handles body.

The top of above-mentioned left handle body and a kind of connected mode between the right handles body are: the top of handle body is provided with an axis hole leftward, and the connection minor axis that is arranged on corresponding position on the right handles body can rotate in this axis hole.

Above-mentioned right body of tool bit and a kind of connected mode between the left handle body are: be provided with a minor axis in the lower end of right body of tool bit, the freely-movable in the link slot on the handle body leftward of this minor axis.

The utility model has the advantages that: use the tinsmith snips of described structure, operate more laborsaving, convenient.

Embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and using method thereof and advantage are further described.

As shown in Figure 1 and Figure 2, laborsaving tinsmith snips described in the utility model mainly by left and right body of

tool bit

1 and 2 and left and

right handle body

3 and 7 form, wherein left body of tool bit 1 links into an integrated entity with right handles body 7---and referring to shown in Figure 3, left body of tool bit 1 and right body of tool bit 2 flexibly connect mutually by cheek axle bolt 4; The top of left handle body 3 is clamped between right body of tool bit 2 and the right handles body 7.And referring to Fig. 5, shown in Figure 6, the top of handle body 3 is provided with an axis hole 8 leftward, again referring to Fig. 3, shown in Figure 4, is provided with at the corresponding position of right handles body 7 and connects minor axis 5, and this connects minor axis 5 and can rotate in this axis hole 8; In addition, and for example Fig. 7, shown in Figure 8 is provided with a minor axis 6 in the lower end of right body of tool bit 2, the freely-movable in the link slot 9 on the handle body 3 leftward of this minor axis 6.

The using method of the laborsaving tinsmith snips of said structure is identical with the using method of the tinsmith snips of traditional structure, repeats no more.Its difference is: be applied to the power on two

handle bodies

3 and 7 when the operator uses, after must connecting

minor axis

5 and 6 by two, just can be delivered on two body of

tool bit

1 and 2 by cheek axle bolt 4 again, wherein, two connected modes that connect

minor axis

5 and 6 have been equivalent to play the effect of a lever, make the active force that acts on two body of

tool bit

1 and 2 obviously increase, thereby when shearing, reached the labour-saving purpose.

Claims

1, laborsaving tinsmith snips mainly are made up of left and right body of tool bit and left and right handle body, and wherein left body of tool bit and right handles body link into an integrated entity, and left body of tool bit and right body of tool bit flexibly connect mutually by cheek axle bolt; It is characterized in that: the top of left handle body connects minor axis by one and the right handles body flexibly connects, and the lower end of right body of tool bit flexibly connects by another minor axis and left handle body, and the top of left handle body is clamped between right body of tool bit and the right handles body.

2, laborsaving tinsmith snips as claimed in claim 1, it is characterized in that: a kind of connected mode between the top of left handle body and the right handles body is: the top of handle body is provided with an axis hole leftward, and the connection minor axis that is arranged on corresponding position on the right handles body can rotate in this axis hole.
