Have tank filler sleeve on the described sleeve, piston also has oil filler point, and tank filler sleeve and oil filler point lead to the cavity of piston, and has plug on the tank filler sleeve.
All has sealing ring between described sleeve and the piston and between sleeve and the plunger.
Between described screw mandrel and the piston back-moving spring is housed.
Also be set with fixed cover on the described sleeve, screw rod passes fixed cover and fixedlys connected with fixed cover.
Also pass through the alignment pin positioning and fixing between described sleeve and the screw mandrel.
Described screw mandrel is positioned at the outside of base, also is fitted with the bearing link stopper between base and sleeve.
After adopting said structure, because the other end of described screw mandrel is fixedlyed connected with sleeve, be provided with piston and plunger in the sleeve, have through hole on the screw mandrel, be installed with push rod in the through hole, an end and the moving jaw of push rod offset, and the other end and the piston of push rod offset; Also be fixed with nut on the sleeve, nut thread is connected with screw rod, and an end and the plunger of screw rod offset, and the other end of screw rod is fixedlyed connected with handle; Have the sliding pin hole on the nut, sliding pin is equipped with sliding pin in the hole, and the top of sliding pin has oblique face, has stop on the screw rod, has the guide runner that is complementary with oblique face on the stop; Can increase the thrust of moving jaw by the promotion of plunger, thus the clamping force of increase flat-nose pliers that can be stronger.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described specifically.
Shown in Fig. 1～7, a kind of hand-hydraulic flat-nose pliers, comprise that base 1, base 1 are provided with regular jaw 2 and screw mandrel 4, an end of screw mandrel 4 is fitted with moving jaw 3, and the other end of described screw mandrel 4 is fixedly connected on an end of sleeve 5, be provided with piston 6 and plunger 7 in the sleeve 5, have through hole 4-1 on the screw mandrel 4, have push rod 18 among the through hole 4-1, push rod 18 passes from the through hole 4-1 of screw mandrel 4, one end and moving jaw 3 offset, and the other end and piston 6 offset; Also be fixed with nut 8 on the sleeve 5, nut 8 screw rod 9 that has been threaded, and an end of screw rod 9 and plunger 7 offset, and the other end of screw rod 9 is fixedlyed connected with handle 10; Have sliding pin hole 8-1 on the nut 8, in the 8-1 of sliding pin hole sliding pin 11 is housed, the top of sliding pin 11 has oblique face 11-1, has stop 9-1 on the screw rod 9, has the guide runner 9-1-1 that is complementary with oblique face 11-1 on the stop 9-1.
Shown in Fig. 5,7, have tank filler sleeve 5-1 on the described sleeve 5, piston 6 also has oil filler point 6-1, tank filler sleeve 5-1 and oil filler point 6-1 lead to the cavity 6-2 of piston 6, and have plug 12 on the tank filler sleeve 5-1, the utility model injects hydraulic oil among the cavity 6-2 with piston 6 in use, by the effect of oil pressure, piston 6 is backed down, promote push rod 8 moving jaw 3 is held out against.
Shown in Fig. 1,5, all have sealing ring 13 between described sleeve 5 and the piston 6 and between sleeve 5 and the plunger 7, can well guarantee between sleeve 5 and the piston 6, and the sealing between sleeve 5 and the plunger 7, prevent hydraulic fluid leak.
Shown in Fig. 1,5,6, between described screw mandrel 4 and the piston 6 back-moving spring 14 is housed, when resetting, piston 6 is resetted like this by back-moving spring 14.
As shown in Figure 1, also be set with fixed cover 15 on the described sleeve 5, screw rod 9 passes fixed cover 15 and fixedlys connected with fixed cover 15, can guarantee the spin stabilization of screw rod 9.
Shown in Fig. 1,6, also by alignment pin 16 positioning and fixing, guarantee can not produce relative rotation between sleeve 5 and the screw mandrel 4 between described sleeve 5 and the screw mandrel 4.
As shown in Figure 1, described screw mandrel 4 also is fitted with bearing link stopper 17 in the outside of base 1 between base 1 and sleeve 5.
The utility model is when clamping work pieces, and turning handle 10 drives nut 8 rotations by sliding pin 11, drive sleeve 15 rotations again, screw mandrel rotation simultaneously drags moving jaw 3 fast moving and clips to workpiece, when clipping to workpiece, the screw mandrel rotational resistance increases, but handle forces sliding pin to skid off outside the groove of screw rod also in rotation, screw rod continues rotation and advances, plunger is pushed to reach, the oil pressure in the plunger shaft is raise, continue top tight workpiece forward and promote piston.When unclamping workpiece, in like manner, handle reverse, screw rod 3 retreats, and piston and plunger automatically reset by spring, thereby unclamp workpiece.
