Abstract
The invention discloses a pipe wrench. The pipe wrench comprises a main shaft, an upper beam and a lower beam, wherein the main shaft is fixedly connected with the upper beam, the main shaft penetrates through a through hole of the lower beam, both the upper beam and the lower beam are provided with fastening teeth, a wedge-shaped fastening plug is further arranged in the through hole of the lower beam, the bottom of the fastening plug is movably connected with a wrench column, and the wrench column is movably connected with the lower beam and is further movably connected with an elastic column. By means of the structure, the pipe wrench can carry out fastening conveniently, a user can finish a fastening process with one hand, and meanwhile the pipe wrench is low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of clamping tool, specifically a kind of pipe wrench.
Background technology
Pipe wrench is the instrument that often is used in daily life, and the conventional structure of pipe wrench does not significantly change within a very long time, and this structural design is simple, manufacturing cost is not high, but well-known, conventional pipe wrench is heavier, its clamping process needs a hand to catch the pipe wrench handle in addition, another hand carries out fastening, generally can't singlehanded complete operation, under indivedual occasions, in the time of can't bimanualness, the use of pipe wrench can be met difficulty.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of pipe wrench is provided, it can carry out fastening, simple to operate comparatively easily.
For solving the problems of the technologies described above, a kind of pipe wrench of the present invention, comprise main shaft, upper beam and underbeam, described main shaft and upper beam are affixed, and described main shaft passes from the through hole of underbeam, described upper beam and underbeam are equipped with fastening teeth, also be provided with the fastening plug of wedge shape in described underbeam through hole, this fastening plug bottom is flexibly connected with pulling post, describedly pulls post and underbeam flexible connection, described pulling on post also is connected with elastic, and the two ends of this elastic offset respectively at main shaft and fastening plug.
Above described underbeam lower end be provided with stator, this stator is provided with through hole and corresponding bearing pin, described post and the elastic pulled is all by bearing pin and stator flexible connection.
Above be socketed with sleeve on described main shaft, this sleeve bottom is provided with hook.
Above described fastening plug bottom be provided with a projection, the described post upper end of pulling is stretched in locating hole on projection.
After adopting such scheme, it can carry out fastening comparatively easily, and one hand just can be completed fastening process, and this structure fabrication cost is lower in addition.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of pipe wrench of the present invention.
Fig. 2 is the enlarged diagram at a kind of pipe wrench A of the present invention place.
The specific embodiment
As shown in Figures 1 and 2, a kind of pipe wrench of the present invention, comprise main shaft 7, upper beam 1 and underbeam 3, described main shaft 7 is affixed with upper beam 1, and described main shaft 7 passes from the through hole of underbeam 3, described upper beam 1 and underbeam 3 are equipped with fastening teeth 2, also be provided with wedge shape in described underbeam 3 through holes, these fastening plug 5 bottoms are flexibly connected with pulling post 6, and the described post 6 of pulling is flexibly connected with underbeam 3, described pulling on post 6 also is connected with elastic 10, and the two ends of this elastic 10 offset respectively at main shaft 7 and fastening plug 5.
Described underbeam 3 lower ends are provided with stator 11, and this stator 11 is provided with through hole and corresponding bearing pin 4, describedly pull post 6 and elastic 10 can be flexibly connected by bearing pin 4 and stator 11.
Described fastening plug 5 bottoms are provided with a projection 12, and described post 6 upper ends of pulling are stretched in locating hole on projection 12.
Described underbeam 3, underbeam 3 through holes, main shaft 7 belong to prior art with underbeam 3 annexations, no longer describe in detail here.
The purpose of elastic 10 is in order automatically fastening plug 5 to be headed in main shaft 7 and underbeam 3 gaps.
Be socketed with sleeve 8 on main shaft 7, these sleeve 8 bottoms are provided with hook 9.Sleeve 8 can extend the entire length of pipe wrench.
For making fastening plug 5 have better fastening effect, the through hole of the underbeam 3 that main shaft 7 passes can little for top, following large horn-like through hole.
During use, the hand-held main shaft 7 of user makes upper beam 1 and the underbeam 3 need the gig clamping, fastening plug 5 is filled in the gap of underbeam 3 and main shaft 7 in the through hole of underbeam 3, fastening plug 5 pushes to upper beam 1 direction, treat upper beam 1 and underbeam 3 will treat gig fully clamp can start the rotation, after rotation, promoting to pull post 6 with finger rotates, pull post 6 drive fastening plug 5 lower ends, upper ends and move downward, fastening plug 5 can be unclamped and extracts out from gap, then upper beam 1 and underbeam 3 can unclamp.
