Universal ratchet socket wrench

Abstract

The invention discloses a universal ratchet socket spanner which comprises a spanner body, a socket adapter tube, a swivel connecting piece, a driving head and a cover body, wherein the spanner body is provided with an accommodating groove and a bearing groove; a gear is mounted in the accommodating groove; a ratcheting block meshed with the gear is mounted in the bearing groove; the gear is a ring-shaped gear of which an outer ring is provided with gear teeth; the swivel connecting piece comprises a positioning shaft and a rotating shaft; the driving head covers the swivel connecting piece and is in running fit with the rotating shaft; a rotating passage for enabling the positioning shaft to enter is formed at the position, which corresponds to the positioning shaft, on the driving head; the cover body covers rabbets of the accommodating groove and the bearing groove and is used for limiting the gear and the ratcheting block to be disengaged from the rabbets; the socket adapter tube is mounted on the driving head. The driving head rotates in a three-dimensional space at a random angle; the universal ratchet socket spanner has a simple structure; parts inside the universal ratchet socket spanner are tightly matched; gear disengaging and stress concentration can be prevented; moreover, the universal ratchet socket spanner is smooth to work, has the characteristics of low fault rate, low back repair rate, low maintenance cost, low cost and the like and can be suitable for various working environments.

Description

technical field [0001] The invention relates to a wrench, in particular to a universal ratchet socket wrench. Background technique [0002] Ratchet wrench is a manual screw tightening tool. The commonly used ratchet wrench rotates in two directions. It is difficult to operate in the environment of bolts or nuts in narrow spaces or inaccessible positions, and the work efficiency will be very low. Chinese Patent Application Publication No. CN103372833A, the patent name of which was published on October 30, 2013 is "Ratchet Wrench", which discloses a device that can stably switch the direction of rotation of the driving wheel, and can achieve a better braking effect of the card. A ratchet wrench that adjusts the force angle of the tool when working with different space restrictions. The Chinese patent authorization announcement number is CN102019595B, and the authorization announcement date is October 30, 2013. The patent name is "Ratchet Wrench", which discloses a method that...

Problems solved by technology

[0003] However, although the above-mentioned disclosed ratchet wrench can to a certain extent operate the screws in the narrow and deep space, the swing range of the working end on the ratchet wrench is relatively small, especially the swing range directly affects the cooperation between the driving wheel and the driven wheel. The greater the swing range, the lower the tightness. Once the tightness is too low, it will affect the cooperation between the driving wheel and the driven wheel of the ratchet wrench, and it is easy to lose teeth between the driving wheel and the driven wheel, or the driving wheel and the driven wheel Stress concentration at indirect contact
