The effect is that the power tool can output _, loose bolts and other locking components; therefore, the gas / hydraulic cylinder can be said to be the most important one of the power, because The power of the round will directly affect the user's effectiveness. Because the pneumatic tool is part of the structure of the complementary technology, the structure of the red needle is exemplified. In order to make the power tool have better wheel power, suppression and noise: noise and other factors, the current series of power tools on the market (four) changed to double-cylinder β and rushed to make the red room section present a similar runway The shape of the space _, so the force of the blade on the shaft of the blade must be by the spring and the opposite direction _ force wheel out, the surface of the slanting object 煞 = = = wall waist phase phase of the resilience system is the largest, will make Dynamic reading ^ _ speed reduction shadow (four) force tool wheel (four) rate, _ and the beginning of the phase, often caused by excessive friction of the material wall M370476 like ^ often replace the blade or rainbow body, resulting in inconvenience in use.

The above and other objects and advantages of the present invention are obtained from the detailed description of the selected embodiments and the accompanying drawings. Of course, the present invention allows for different 'on the other parts, or the arrangement of the parts. However, the selected embodiment is described in detail in the present specification. [Embodiment] This creation department has a new type of power-hydraulic hydraulic red structure. Please refer to the figure-to-micrograph, which mainly includes the cylinder installed in the moving red (1) 0), a power output shaft (20) axially arranged on the axis of the cylinder (1 ◦) and shouting on the power output shaft (2 ◦) and radial with respect to the power output shaft (2Q) Reciprocating blade (3〇). The cylinder (1 〇) is formed with a trough-shaped trough (1 1 ). The power output shaft (20) is formed at each of its two diameters with a longitudinal slot (2 1 ) respectively, and the two slots (2 1) are parallel to each other by a first through hole (2 2) The second perforations (23) are in communication with each other. The two blades (30) are respectively received in the two slots (21), wherein the mother blade (30) has a flat first end edge and a second end edge formed in an arc shape, and A first notch (3 1 ) and a second notch (3 2 ) are respectively formed at two ends of the first end edge, and the bottom surface of the two notches (3 1/3 2 ) is vertically recessed with a first a recessed hole (3 1 1 ) and a second recessed hole (3 M370476 21)' wherein the first recessed hole (311) and the second recessed coaxial portion are disposed in the first through hole (2 2) and the second through hole 3 21) splitting through the first through hole (22) and the third through hole (3), respectively, and the second spring (34), wherein the first spring 1 (33) is accommodated in the two blades ( The two ends of the first recessed hole (3) of the third recess (3) are respectively accommodated in the two blades (and the second spring 1), and the extra-tickets are μμ〇〇, 弟二凹孔( 3 2 The two blades (3 〇) can be moved relative to the power wheel (2 (1) position in the double movement. In addition, each blade (3 〇) is placed in the longitudinal direction of the flute (3 5), too - end The edge is formed with a groove (35). In the preferred embodiment, the two have The parallel side walls and the section are semicircle/(=5), and the middle is the county-country-the first needle-roller (36)^. The accommodating tank is Ganshi, (9) Sichuan and a younger two needles ( 3 7), - The 'the diameter of the first needle (36) is smaller than the width of the accommodating groove (35) and the outer edge of the second needle (37) is attached to the accommodating groove (3 5 ) the two side walls 'and extend out of the accommodating groove (35) to abut against the inner wall of the cylinder ((9) through the groove (11), so that the friction between the rainbow body (1◦) and the blade (30) is The traditional sliding friction is converted into rolling friction, and the contact mode between the cylinder (i◦), the needle (3 6 , 3 7) and the blade (3 〇) is line contact, and only five contact lines make power The miscellaneous force in the tool oil red is minimized, especially when the blade (3 Q ) is to pass through the waist of the city (i ◦) through the groove (丄1) to capture the two bullets (3 3/3 4) When the shrinkage reaches the maximum, the effect is more remarkable. This not only can the output of the wire tool, but also greatly reduce the maintenance cost of the blade (30). M370476 Please refer to the fifth to sixth figures. Show that it is a creative blade (3 In the second embodiment of the present invention, in the embodiment, the accommodating groove (35,) is a stern groove structure, and each blade (3 〇,) contains a shouting device. 5) the first needle on both sides of the bottom surface (36) and the first needle roller supported by the two needles (36) and attached to the inner wall of the cylinder (丄) 3 7) 'Axis' cylinder (10) and needle roller (3)

However, for the whole _cylinder, there will be an increase in the amount of the sun and the second needle (3 7). support. As shown in the seventh figure, when the sphere (or cylinder) rolls in a plane, the I plane will be shouted by the pressure of the sphere (cylinder), thus producing a rolling resistance. The handle is a rolling rubbing force. The larger the dent, the greater the rolling friction. As shown in the figure, the weight W of the steel column is placed on a plane, and the plane is concave due to the pressure. The force P is applied to roll the steel column: P = rolling friction force f = Wxa / r, a is the rolling friction coefficient, Γ Semi-kneading for steel columns *.* ΣΜα= 0 , 〇B%r Due to the creation of the first-needle (3 6) and the second light, it is almost impossible to re-read the phase on the rigid PTO shaft 7 7 The needle (36) and the second needle (37) π turn, and also modest, - M370476 friction total also approaches zero. Therefore, this creation can indeed divide the financial power county to reduce the rim power of the power guard and extend the service life of the internal components in the hydraulic cylinder while reducing the friction. Repair and maintenance costs. The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.
