Description

Multifunctional ratchet wrench

Technical Field

The utility model relates to an electric power tool technical field, in particular to multi-functional ratchet spanner.

Background

In the electric power construction installation site, bolts are used as links for connecting and fixing primary equipment on site, but because field equipment is different in size and fixing bolts required to be used are different (the approximate type interval is M6-M51 at present), wrenches of different types and sizes are required to be prepared for time to time when bolt screws of different types are disassembled and installed. However, the frequent replacement of the wrench on site also causes a certain delay to the construction period of the site construction operator.

The bolt is disassembled and assembled on the construction site at present, and the following problems exist:

1. the dismounting personnel need to frequently replace the wrench for dismounting, so that the dismounting efficiency is influenced;

2. the disassembly and assembly work needs to be carried out at a high place, and the risk of falling or injuring others when carrying various wrenches is caused;

3. many wrenches can only be disassembled in a small range, and the disassembly time is long;

4. too many different models of wrenches delay changing and finding.

Disclosure of Invention

To the problem that above-mentioned prior art exists, the utility model provides a multifunctional ratchet spanner, its structure is: the adjustable wrench comprises a lower movable jaw (2), a wrench body (3), a turbine (4), an upper movable jaw (5), a fixing pin (6), a ratchet wheel (7), a spring (9), a cam (10), a cylindrical pin (12), an operating handle (13), a circular shaft (14) and a flat key (15), wherein the operating handle (13) is a cylinder, the right end of the operating handle is provided with an inner hole, 2-4 through holes (11) are formed in the direction vertical to the inner hole, the operating handle (13) is sleeved with the left part of the wrench body (3) through the cylindrical pin (12), the left part of the wrench body (3) is cylindrical, 2-4 through holes (11) corresponding to the operating handle (13) are formed in the cylinder, the circular shaft (14) is arranged in the middle of the wrench body (3), the circular shaft (14) is connected with the ratchet wheel (7) through the flat key (15), and a ratchet claw (8) is arranged on the ratchet wheel (7), the left part of the ratchet wheel (7) is provided with a cam (10), the cam (10) is in a shape of Chinese character 'ren', a spring (9) is arranged on the wrench body (3) and perpendicular to the direction of the cam (10), one end of the cam (10) is obliquely inserted into the ratchet claw (8) through the spring (9), the other end of the cam is lapped on the edge of the ratchet claw (8), the right part of the wrench body (3) is in a shape of a stiff wrench, the end part of the stiff wrench is provided with threads, and the end part of the stiff wrench is respectively in threaded connection with the internal threads (1) on the lower movable jaw (2) and the upper movable jaw (5) through a turbine (. The right part of the operating handle (13) and the left part of the wrench body (3) can be telescopically adjusted.

The utility model discloses a use method: before the assembly and disassembly, a user firstly adjusts the lower movable jaw and the upper movable jaw according to the size of the bolt to adapt to the S size of the bolt head, then adjusts the ratchet direction control handle according to the actual field (whether the bolt is assembled or disassembled), and can adjust the telescopic handle to extend according to the torque required by a larger bolt, so that the bolt can be assembled and disassembled in the easiest way.

The beneficial effects of the utility model reside in that: the multifunctional ratchet wrench is convenient to carry, saves labor and time, increases working efficiency, reduces risks in work, and can be suitable for disassembling bolts (M2-M51) of different types.
