To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

Referring to fig. 1-6, in the present embodiment, a power saving vise is provided, including: the handle comprises two arc handles 1 which are symmetrically arranged, wherein a first tooth group 101 is arranged on the upper side of one end of each of the two arc handles 1, and a plurality of second tooth groups 102 which are meshed with each other are arranged on the opposite sides of one ends of the two arc handles 1;

the upside of two arc handles 1 has two looks rotary fit's binding clip 3 through first tooth group 101 meshing, and the lower extreme of binding clip 3 is equipped with third tooth group 301, and two third tooth groups 301 mesh rather than two first tooth groups 101 relative.

Specifically, the method comprises the following steps: when using this vice, rotate and hold two arc handle 1 earlier, there are two second tooth group 102 of an intermeshing between two arc handle 1, when arc handle 1 was opened, the engagement structure made two arc handle 1 symmetry angle open, when making two arc handle 1 be close to each other, two first tooth group 101 will be exerted the power on the handle and transmit to two binding clip 3 through two third tooth group 301, can use binding clip 3 to carry out the centre gripping, and the reference circle diameter of third tooth group 301 is greater than the reference circle diameter of second tooth group 102, produce laborsaving effect.

The axis of rotation of arc handle 1 is second pivot 5, and the axis of rotation of binding clip 3 is first pivot 4, and the relative position of first pivot 4 and two second pivots 5 is fixed, consequently, binding clip 3 keeps meshing with arc handle 1 all the time in the use, does not take place translational motion.

The first tooth group 101 is used for transmitting the force applied on the handle to the tong head 3, the second tooth group 102 on the arc-shaped handle 1 is meshed with the third tooth group 301 on the tong head 3, and the reference circle diameter of the third tooth group 301 is larger than that of the second tooth group 102, so that the labor-saving effect is achieved.

There are also two second sets of teeth 102 engaged with each other between the two arc-shaped handles 1. When the arc handles 1 are opened, the engagement structure enables the two arc handles 1 to be opened at symmetrical angles.

Casing 2 is the subassembly of connecting binding clip 3 and arc handle 1, guarantees the stability in the vice use, and casing 2 has two, uses bolt and nut (being the aforesaid first pivot 4, the second pivot 5 of saying promptly) to connect after the assembly, and 2 surperficial cloth strengthening ribs of casing and edge mutually support to strengthen casing intensity.

Through cutting apart arc handle 1 and binding clip 3, separately as laborsaving lever structure, utilize tooth transmission, will be used in the input moment on arc handle 1 and transmit to binding clip 3 that has third tooth group 301 through first tooth group 101, make the laborsaving effect stack of two-stage, reach more laborsaving effect.

As shown in fig. 5, the shell 2 is installed on both sides of the upper end of the binding clip 3 and the arc handle 1, a wedge 201 is installed on one end of the shell 2, a wedge opening is installed on the other end of the shell 2, and the wedge 201 of one shell 2 is matched with the wedge opening of the other shell 2.

As shown in fig. 3, two binding clip 3, through connection has first pivot 4 between two casings 2, through connection has two second pivot 5 between two casings 2 and two arc handles 1 respectively, first pivot 4, the one end of second pivot 5 all is equipped with the screw thread, first pivot 4, the screw thread end of second pivot 5 runs through casing 2 and threaded connection has first nut 6 respectively, second nut 7, casing 2 has two, use bolt nut (be said first pivot 4, second pivot 5) to connect after the assembly, casing 2 surface cloth strengthening rib and edge are mutually supported, in order to strengthen casing intensity, the opposite side of two binding clip 3 is equipped with cuts and the centre gripping mouth.
