Description of the Invention: [Technical Field] The present invention relates to a labor-saving tool, in particular to a working end having two relatively openable working ends, and the working end is completed when relatively closed. The labor-saving tool achieves the purpose by designing the connecting rod, and can generate no component force at the maximum resistance, so as to meet the user's labor-saving requirements. [Prior Art] Referring to Figure VIII, a conventional tin shear is known. The sheet shear includes two opposite grip ends and two shear ends extending from the grip end, and the two shear ends are framed and the crescent is relatively open. Since the iron sheet is made of a metal material and has a high hardness of the material, the iron sheet is a shear which is not easily cut, and it is necessary to apply a large force to perform the shearing action. In the past, in order to save the iron sheet and extend the grip end, the iron shear has a long force arm, and the force-applying arm is used to save labor. Referring to Figure 9, a conventional crimping tool is used. The crimping tool includes two opposite grip ends and two crimping ends extending from the grip end, and the two crimping ends are pivotally connected to be relatively open. The purpose of the crimping tool is to flatten the wire or to flatten the terminal that is bonded to the wire to smoothly connect the wire to the wire. Whether the wire is flattened or the terminal is flattened, a large force must be applied. Can complete the action of pressing the line. In order to extend the grip end in a relatively labor-saving pressure line, the crimping tool has a long force-applying arm, and the force-applying arm is used to achieve labor-saving effect. However, the design of the extended extension arm is traditionally designed. The longer the arm is, the shorter the arm is, the shorter the arm is, the shorter the resistance arm is, the more it is necessary to increase the sheet metal shear or the second line!:: inch' large size The design will increase the selling price, and the cumbersome appearance, easy to collect and can not get the favor of consumers, so Shenxun 2: propose a kind of sigh juice with labor-saving effect and no need to increase the force arm, hunting to improve the prior technology Missing. SUMMARY OF THE INVENTION The 'Liri Tools' is intended to solve the shortcomings of the prior art. - Labor-saving: Two advantages are provided by structural changes, 1 rain. Keep a small size that is easy to carry and has a length between the second: =:= etc. and between the working ends of the second grip. 'To the length of the piece - the knife - and the length of one third for the money (four) effect, by the * link relative movement, with the work =: Γ _, the labor efficiency is better, there is a force to reach the time ~^ 抵楼===r;r When used, the fulcrum, the component force is reached; ^:^: The pivotal joint of the holding member forms a straight line, so that the novel characteristics of the invention will be described in detail below. The drawings are more obvious. [Embodiment] 4 1354602 The technology, the means and the preferred embodiment of the present invention are described in detail with reference to the drawings, and this is only for the purpose of the force effect.

At this time, the first section of the resistance arm ρι is not a straight line between the second force applying arms F2, so the force FB generates two component forces FX and force ργ at the point of arrival B, and the force arm F2 is vertical , the force FY and the force FB form - angle ^ the = θ is - acute angle. It can be known from the trigonometric function that FY=(3)S0*FB, because the angle=is an acute angle', so the (3)s(four) value is less than 1, and once again brings the aforementioned lifting type, it can be known that the force FY must be smaller than the force FB. It is consumed and cannot be transmitted 100%. Referring to FIG. 6, a schematic diagram of a labor-saving tool for metal shears according to the present invention is shown. The present invention is implemented as a labor-saving aid for the metal scissors, which is held by two 7 Π〇 Τ 2°, and is pressed against the floor 341 of the pressure block 34 by the pressing portion 13 of the first holding member 10, The late member 3◦ is resisted and pivoted relative to the j-grip member 2G, and the working end 32 of the pressing member 3G faces the second holding member 20 of the guarding end 22 _, when the two working ends 22 Placed with metal (4) 'The work ends of the two working ends 22, 32 are relatively closed when the cutting is completed. The scales have no component to produce the best labor-saving effect. When the labor-saving tool of the present invention cuts the metal piece, the first-stage resistance arm Μ ^ two-stage force-applying arm F2 is in a straight line 'the force FY is perpendicular to the second-stage force-applying arm 2'. The force FB is equal to the force FY The force FB has no component force. Because of this force FB can touch the red pass to force Ρ γ. When the cutting work is performed, the fulcrum A, the «point B, and the pressing portion 3Q and the second gripping member 2 〇 can be formed into a straight line, that is, no component force is generated, so that the applying force acts almost on the shearing Cut the work, and achieve the goal of saving effort. In the position where the maximum force is required in the present invention, when the labor-saving tool cuts the metal piece, since there is no component force generated, the force of the transfer process towel is not consumed, and the labor saving ratio is. The ratio of the force Ρ to the force F can be used to know the multiple of the labor saving. Referring to Figure 7', there is shown a schematic view of the operation of the second embodiment of the labor saving implement of the present invention. A second embodiment of the present invention is an embodiment in which the labor saving tool is implemented as a crimping plier. The difference between this embodiment and the first embodiment is that the working end 22a of the second holding member 2 is implemented as a pressing portion and the working end of the pressing member 30 is ordinarily embodied as a pressing portion. When the labor-saving tool of the present invention is implemented as a crimping tool, it can be generated by the operation of the labor-saving tool without component force, so that the force applied to the work of the pressure line is almost achieved, thereby achieving the purpose of labor saving. 1354602. As described above, the present invention can be summarized as follows: 1. The "saving tool" of the present invention provides a labor-saving tool by structural change, and the labor-saving tool can have the advantages of being small and easy to carry. The lengths of the two working ends are about equal, and the length of the working end of the second gripping member is between one-half of the length of the second gripping member and one-third of the length. 2. The "saving tool" of the present invention can provide a design with no component force when the maximum force is required, that is, when the work is relatively close, thereby achieving the purpose of saving effort. 3. The "saving tool" of the present invention, by use, the fulcrum, the abutting point, and the pivoting portion of the pressing member and the second holding member form a straight line, so that the component force is 0, and the optimal force applying effect is achieved. . The above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so that the numerical value is changed or the equivalent element is replaced, or the equivalent of the scope of the patent application of the present invention. Changes and repairs should still be covered by the patents of this invention.
