Description

[Detailed description of the invention] name of invention ratchet spanner technical field The invention relates to hand tools, especially reversible ratchet spanners for rotating fasteners.

Background of the invention Ratchet spanner’v? A diameter smaller than a regular spanner with one end closed or open. There are some advantages. The fastener to be tightened or loosened is generally When the spanner is in a limited location with only a limited arc of motion, Ru. For open-ended or closed-ended spanners, this spanner is Each time you make a mistake, you must remove the tightening from the tool and put it back on the next time. ratchet The wrench is held in a tightening device, and the wrench is removed from this tightening device from the ratchet (gcc). This wrench can be easily adjusted to the initial movement point without having to do so. reversible ratchets When installing the wrench, the wrench can be turned freely in either direction as needed. Ru.

Ratchet spanners traditionally have closed or open end spanners, but one notable drawback is that There is. The wrench connection surface of the tightening tool is such that the spanner connection surface of this IR fitting is 2g long. If it is an ordinary automatic military spark plug that fits in your hand or a bolt that tightens the tightening odor. 5 when the piece extends through the fitting, a considerable distance from the end of the fastener. There are many cases where there are 4 times. A regular spanner with a closed or open end can be used to tighten the spark plug or bottle. The wrench link surface 7c of the fastener can easily slide over the end of the bolt. usually The ratchet spanner has a rectangular drive body connected to a rectangular hole in the socket. There is a certain temperature. According to ℃ socket is a wrench face with a wrench smell? : Can be made to touch This depends on the length of the socket. In long accounts, the lengths are different2 The return of the 1- socket is the so-called short socket and spark plug that are used in the shortest area. Use 5 Many uses for so-called frozen sockets, including r, /c, and w through bolts. Requires fasteners, etc. In this case, you need to purchase +all 2 sockets for each child. It costs a lot of money to use longer and “deeper” sockets and spanners. When inserting a wrench from the handle to the tightening tool, the user must tighten the wrench. To prevent excessive stress caused by attachment yc, the moment perpendicular to the direction of rotation of the lid is If you don't pay attention to point 5, you won't fall.

A ratchet that has a spanner prize and is aligned with the rotating shaft area of the ratchet spanner drive part. By providing a ratchet spanner, multiple length sockets can be added to the ratchet spanner structure. Proposals have been made to eliminate the need for pairs.

U.S. Patent No. 1125,695 to 5anborn 1% rice license with Mossberg as the inventor: 1,165.99 No. 5 and U.S. Pat. No. 2,317,461 each disclose a lathe with one through hole in the cover. There are 2 = self-loaded t on the wrench. The spanner in each of these patent specifications is a single Compatible only with fastener dimensions. 7 Orton (Forton) as the inventor America! #Grant No. 1.347,691 and Wilson ('1vilion) Each specification with U.S. Patent No. 2.300.479 as the inventor is Compatible sockets can be used for a range of fastener sizes. There is "C" and "℃" for the ratinotosbaka with a through hole.However, these patent specifications For spanners listed in °C, do not turn the wrench in the opposite direction. I can only do the opposite. In addition, these constructions are compatible with standard square drive sockets. Sokunoto with equivalent amount, strength, strength and size range = no use ℃, therefore It can hardly compete with the standard square drive socket.

When using a ratchet spanner with a socket set of VC 5 to 5, the spanner may not open during use. It is common to provide a spring-loaded detent to secure the socket to the drive piece. .

Nowadays, the socket can be quickly released from the wrench by retracting the stop. A mechanism has been developed. This kind of 'Fli structure is similar to that of Roberts. ) and U.S. Patent No. 5.208.518 to Haznar. ) Each specification with US Patent No. 5.532,013 as the inventor (C listed) Ru. However, these mechanisms are expensive and difficult to disassemble for repair. Requires dry parts.

Many (ordinary ratchet spanners have no ratchet mechanism)Y spanner 1. so that it rotates in the desired direction. al, Mf A rotation of fI9° can be generated between the spanner and the wrench. Ratchets in a gathering place Some spanners have been developed that can reduce the angle mentioned above so that the spanner can be used more evenly. However, this 2-'L letter '04 is enough to satisfy the samurai. not present. Another area where the ratchet spanner is not effective is the tightening lever or the V back loosening. Make sure that the socket and wrench do not touch the said piece. This is when adjacent to the fault type. Accordingly, the above part can be attached to the However, if the spanner itself cannot be fixed in the socket, use a ratchet spanner. is not valid.

Cursed does not require multiple W sockets. The quick release mechanism works together to achieve the desired benefits, and the ratchet spa is ready for use. na has not been developed. Accordingly, C barrel making can cater to a relatively uncomplicated and inexpensive heritage. You'll need a box wrench that's as big as the second one.

Summary of the invention In 1911 by Fugenmei, a ratchet spanner that rotates the hatchet was obtained. Unra The Chet Spanner carries a handle with a head on one end. This head has this 7 It has a cylindrical hole extending through it and centered on the lacrimal.
