Between the front ends of the 34, one end of the elastic member 37 abuts against the rear end of the second outer sleeve 22, and the other end abuts against the front end of the second clutch ring 34, so that the constant force mechanism 3 can be restored after the actuating mechanism 3 is actuated. Bit 9 M408454 Refer to the third figure. 'When this creation is used, the user's 刻度 棘 棘 棘 定 定 定 定 的 的 32 32 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量 力量The element 353 is slid into the locating groove 345 bears of the different class faces 343 in the second clutch boring tool, and the "face rotation" is displaced by the front and rear of the 34, and is kept with the first clutch ring 33. When the user inserts the wrench into the force-fixing mechanism 3: the hand: 22, the first screw 26 is rotated (the second clutch Lu = the ring 35 and the scale ring 32 are synchronously rotated). , does not change the room::; force:: the ball 273 of the clutch structure 27 causes the snail 26 to synchronously drive the 匕 22, the first coat 2, the connecting member 23, the needle roller 2 and the screw further enable the screw 15 to drive the movable jaw 13 to move forward quickly to the work as shown in the figure IX. When the movable jaw 13 is pressed against the workpiece: for the user to continue to rotate with the wrench The wrench sleeve 36 will block the movable 颚丨3 force due to the work, so that the screw 15, the first outer sleeve 2 and the second outer sleeve; the second connecting member 23 and the needle roller 24 all stop rotating; The steel ball 273 on the screw (4) is disengaged from the engaging hole 275' by the external thread segment 261 of the screw 26, and the screw is forwardly rotated and advanced. The push rod 25 is pushed forward to open the four needles 24, and the four needles 24 are pushed again. The inclined support surface 222 of the second outer sleeve 22 is squeezed to generate a greater thrust toward the screw 15, so that the screw 15 directly pushes the movable jaw 13 forward, so that the movable jaw 13 can be doubled by the forward movement of the screw 15. The effect of gripping the workpiece by the force 'prevents the movement 13 from loosening due to the vibration force of the cutting process. The force of the force of the above-mentioned s Xuan needle roller multiplying mechanism 2 can be set to a specific force by the constant force mechanism 3 When the factor steel ball 273 is pushed forward from the card hole M408454 275, the wrench sleeve 36 will be pulled synchronously. Pushing the second clutch ring 34, the second clutch ring 34 causes the wedge members 332, 344 to move as the sub-screw 26 rotates and is pushed forward by the wrench sleeve 36 to the rear end surface of the first clutch ring 33. When the first clutch ring 33 and the second sleeve 22 are in a fixed state, the second clutch ring 34 can be locked, and the sub-screw 26 and the wrench sleeve 36 are simultaneously locked and stopped. Therefore, the stroke of the front push rod 25 of the sub-screw 26 is controlled by the spacing d, that is, the effect of a certain multiple force acting on the screw 15 and the movable jaw 13 can be achieved, and the function of the constant force clamping is obtained. With the power effect 'will be able to enter ~ effect. The present invention mainly utilizes two inclined surfaces 2511 and 2511 of the front end of the ejector lever 25, and the angle of the angle is equal to or less than 45, so that the ejector rod 25 can generate a larger thrust when the needle roller 24 is pushed, and the force can reach 6 〇. 〇〇kg/nf, so it can achieve the effect of enhancing the strength. Moreover, since the present invention has a bearing tear roller thrust bearing in the shape of the ejector pin 25 of the ejector pin 25, the friction between the ram 60 and the sub-screw 26 can be reduced, and at the same time, the above-mentioned 25 knot can be achieved. In addition to the labor-saving operation, the structure of the vise body 1 described above is not limited.
