Description

A two-point wrench head

technical field

The utility model relates to the technical field of wrenches, in particular to a two-point wrench head.

Background technique

A wrench is a commonly used installation and removal tool. It uses the principle of leverage to twist bolts, screws, nuts, and other hand tools that hold the openings or sockets of bolts or nuts. Its types usually include ratchet wrenches and torque wrenches. However, although there are many types of spanners in the prior art, there are generally the following problems: 1. Traditional adjustable wrenches, because the movable part is only connected to the fixed part, it is easy to loosen, so it is easy to form a wide outside and narrow inside. The inverted trapezoidal shape of the nut is easy to damage the hexagonal corners of the nut during use; 2. The open-ended wrench, ring wrench, ratchet wrench, socket wrench, etc. are all fixed and non-adjustable wrenches with an open mouth. Two kinds of bolts and nuts; 3, socket wrench, one end is closed, and the nuts with too long bolts cannot be fixed; 4, torque wrench, also have the above problems.

Utility model content

Two-point wrench head.

A two-point wrench head of the utility model comprises a two-point wrench head main body fixedly connected to one end or two ends of the wrench handle, and the two-point wrench head main body is a horizontal clamping wrench head or a vertical clamping wrench head, Wherein, the horizontal clamping wrench head includes a U-shaped base and two first adjustment screws relatively arranged on the top of the base, and the vertical clamping wrench head includes a wrench head seat and a vertically symmetrical wrench head seat fixed on the wrench head seat. Two chucks, the middle of the chucks are equipped with a second adjusting screw.

Further, the wrench head seat includes a ratchet seat and a ratchet plate, the ratchet plate rotates relatively in one direction or two directions on the ratchet seat, and the collet is fixed vertically on the ratchet plate.

Further, the ratchet disc and the ratchet seat are ring-shaped and fitted together.

Further, a two-way preset switch is also provided between the ratchet seat and the ratchet disc, and the two-way preset switch is used to limit the rotation direction of the ratchet disc.

Further, the head of the horizontal holding wrench is provided with a first connecting groove for fixing the handle of the wrench.

Further, the vertical clamping wrench head is provided with a second connecting groove for fixing the wrench handle.

Compared with the prior art, the utility model has the beneficial effects as follows: it includes a two-point wrench head body fixedly connected to one end or two ends of the wrench handle, the two-point wrench head main body is a horizontal clamping wrench head or a vertical clamping wrench head, Among them, the horizontal clamping wrench head includes a U-shaped base and two first adjustment screws arranged on the top of the base, and the vertical clamping wrench head includes a wrench head seat and two collets vertically and symmetrically fixed on the wrench head seat. , the middle part of the collet is equipped with a second adjusting screw; in this way, the nut is not easy to be damaged, and the old nut with various specifications and lengths and damaged corners can be effectively screwed.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1 to 3, a two-point wrench head of the present invention includes a two-point wrench head body fixedly connected to one or both ends of the wrench handle 1, and the two-point wrench head main body is a horizontal clamping wrench Head 2 or vertical clamping wrench head 3, wherein the horizontal clamping wrench head 2 includes a U-shaped base 21 and two first adjusting screws 22 arranged on the top of the base, and the vertical clamping wrench head 3 includes a wrench head seat 31 and two collets 32 vertically symmetrically fixed on the wrench head seat, and the middle part of the collet 32 is equipped with a second adjustment screw 33; the horizontal clamping wrench head is two symmetrical clamps that clamp the outer hexagonal nut horizontally. side, if the nut is less than the clamping distance of the horizontal clamping wrench head, you can adjust the adjusting screws installed on both sides of the base to clamp it. The vertical opening wrench head is two symmetrical clamps that vertically clamp the outer hexagonal nut. If the nut is smaller than the distance between the vertical opening chucks, you can adjust the adjusting screws installed on both sides of the vertical opening chucks to clamp it; due to the two-point fixing method, it will not form a wide outside and narrow inside like an adjustable wrench. Inverted trapezoid, the hexagonal corners of the nut will not be damaged during use; due to the adjustable adjustment screw, bolts and nuts of various specifications can be loosened and tightened.

In order to facilitate screwing, the wrench head seat 31 includes a ratchet seat 311 and a ratchet plate 312, the ratchet plate 312 rotates relatively in one direction or two directions on the ratchet seat 311, and the collet 32 is fixed vertically on the ratchet plate 312; meanwhile, for further convenience Screw the overlong nut of the bolt, the ratchet disc 312 and the ratchet seat 311 are ring-shaped and mutually fitted together, so that the bolt can pass through the ratchet seat and the ratchet disc to facilitate the screwing process.

In order to realize bidirectional rotation and control of the ratchet disc, a bidirectional preset switch 34 is also provided between the ratchet seat 311 and the ratchet disc 312, and the bidirectional preset switch is used to limit the rotation direction of the ratchet disc.

It should be pointed out that the two-point adjustable ratchet plate of the utility model can be used in connection with ordinary handles or with torque handles. The first connection groove 23, the second connection groove 35 for fixing the handle of the wrench is arranged on the vertically clamping wrench head 3; the two connection grooves can be plugged in or threaded, or even connected to the wrench by a rotating shaft The way of the handle, so that the wrench handle can be rotated relative to the wrench head, so as to adapt to different operating environments.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And modification should also be regarded as the protection scope of the present utility model.
