Abstract
The utility model discloses pipe tongs, which comprise a spindle, an upper beam and a lower beam. The spindle is fixedly connected with the upper beam and 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 pull column; and the pull column is movably connected with the lower beam and an elastic column. The pipe tongs can be used for fastening more conveniently, fastening process can be finished with a single hand, and additionally the pipe tongs are lower in manufacturing cost.
Description
Technical field
The utility model 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 have obvious variation in a very long time, and this structural design is simple, manufacturing cost is not high, but well-known, conventional pipe wrench is relatively 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, then the use of pipe wrench can be met difficulty.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of pipe wrench is provided, and 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 utility model, comprise main shaft, upper beam and underbeam, described main shaft is affixed with upper beam, 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 the described underbeam through hole, this fastening plug bottom flexibly connects with pulling post, describedly pulls post and underbeam flexible connection, described pulling also flexibly connects flexible post on the post, the two ends of this elasticity post offset respectively at main shaft and fastening plug.
Be socketed with sleeve on the described main shaft, this cover tube bottom is provided with hook.
Described underbeam upper end is equipped with spring leaf, and this spring leaf other end is crooked and offset with main shaft.
After adopting such scheme, it can carry out fastening comparatively easily, and one hand just can be finished fastening process, and this structure fabrication cost is lower in addition.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of pipe wrench of the utility model.
Fig. 2 is the enlarged diagram at a kind of pipe wrench A of the utility model place.
The specific embodiment
As shown in Figures 1 and 2, a kind of pipe wrench of the utility model, 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 flexibly connect with pulling post 6, and the described post 6 of pulling flexibly connects with underbeam 3, described pulling also flexibly connects flexible post 10 on the post 6, the two ends of this elasticity post 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 13, describedly pull post 6 and elasticity post 10 can flexibly connect by bearing pin 13 and stator 11.
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 elasticity post 10 is in order automatically fastening plug 5 to be headed in main shaft 7 and underbeam 3 slits.
Be socketed with sleeve 8 on the main shaft 7, these sleeve 8 bottoms are provided with hook 9.Sleeve 8 can prolong the entire length of pipe wrench.Underbeam 3 upper ends are equipped with spring leaf 4, and this spring leaf 4 other ends are crooked and offset with main shaft 7.
The purpose of spring leaf 4 is in order to add the space of ambassador's main shaft 7 and underbeam 3, to make fastening plug 5 can fully insert the space, thereby makes main shaft 7 and underbeam 3 fully fixing.
During use, the hand-held main shaft 7 of user make put the beams in place 1 and underbeam 3 need the gig clamping, fastening plug 5 is filled in the slit of underbeam 3 and main shaft 7 in the through hole of underbeam 3, fastening plug 5 pushes away to 1 direction of putting the beams in place, wait to put the beams in place 1 and underbeam 3 will treat that gig fully clamps and can begin rotation, after the rotation, promoting to pull post 6 with finger rotates, pull post 6 upper ends and drive the motion of fastening plug 5 lower ends downward, fastening plug 5 can be unclamped from the slit and extract out, put the beams in place then 1 and underbeam 3 can unclamp.
