Description

A kind of household round wrench and using method

technical field

The invention relates to a round wrench and its usage method, in particular to a household round wrench used in a narrow space and its usage method.

Background technique

A wrench is a commonly used installation and removal tool. Hand tools capable of gripping bolts or nuts and turning bolts, screws, nuts, and other threaded openings, or socketed holes, using the principle of leverage. A wrench usually has a long handle. When in use, an external force is applied to the handle in the direction of thread rotation to turn a bolt or nut. These have a long handle wrench with an increased moment arm and are great for nut or bolt loading and unloading during mechanical assembly, repair, maintenance. But there is a wrench with a long handle, and in some places with small spaces, such as the maintenance and replacement of the water pipe hose of the sanitary toilet of the family and the hotel, the washbasin faucet, the existing long handle wrench is just very inconvenient to use.

Therefore, in a narrow space, it is necessary to use a suitable open-end wrench and its usage method to disassemble the mounting nut or nut.

Contents of the invention

In order to solve the above problems, the technical solution of the present invention is a household round wrench, which is characterized in that: the wrench body is in the shape of a disc, and on the circumference of the circle, it is processed with 4-16 notches that are evenly distributed. The jaws are processed with a central handle hole through the upper and lower sides of the wrench body; the jaws of the wrench body are symmetrical in pairs with the center of the circle, and are divided into small jaws and middle jaws according to the size of the opening. The shape of the jaw is a regular hexagon with two less sides. The sides of the opening are parallel to each other and bisected by the diameter of the circle. The jaws are designed in two shapes, which is convenient for choosing mold processing. There is a large round hole in the middle of the wrench. When using it, first find a suitable jaw, align it with the nut to be twisted, and turn it gently by hand.

In the above technical solution, the wrench body can be folded along the folding shaft processed and installed along the circular diameter line, and the folding shaft of the wrench body is divided into three specifications: one-word folding shaft, cross-folding shaft, and three-folding shaft; the one-word folding shaft is a Through the folding shaft at the center of the circle, the round wrench body is divided into two independent parts; the cross folding shaft is two folding shafts passing through the center of the circle perpendicular to each other, that is, the round wrench body is divided into four independent parts; the three folding shafts are over The three folding axes evenly distributed in the center of the circle divide the round wrench body into 6 independent parts. Each connection of the wrench body is connected through a rotating shaft, or connected through a connection buckle.

In the above technical solution, the wrench body can be folded along the folding axis machined and installed along the circle diameter line, such as the straight folding axis of the wrench body, that is to say, the wrench body is processed into two semicircles and divided into two parts, and the diameter of one semicircle is one end. The sleeve is processed on one side, and the diameter of the other semicircle is processed on the same surface as the shaft. The shaft is inserted into the sleeve to connect the two semicircles and ensure that the diameter planes of the two semicircles are closely attached. The two semicircular surfaces of the wrench body can only rotate towards one surface.

In the above technical solution, the connecting buckle is a strip with one end fixed on a semicircle but rotatable and close to the surface of the wrench body. The other end of the strip has a hook, which can pass through the Rotate to hook the hanging post on the other semi-circular surface. The one-word folding shaft divides the round wrench into 4 parts, the cross folding shaft divides the round wrench into 4 parts, and the three-folding shaft divides the round wrench body into 6 parts. The one-word folding shaft is at the two connecting end faces, and there are two rotating shafts processed, or two connecting buckles processed through each surface of the wrench body, and there are four connecting buckles on the two surfaces, and the connection and fixing of the wrench body are separated. 2 independent parts; the cross folding shaft is at the 4 connecting ends, and 4 rotating shafts are processed, or 4 connecting buckles are processed on each surface of the wrench body, and there are 8 connecting buckles on the two surfaces, which are connected and fixed The wrench body 1 is divided into 4 independent parts; the three folding shafts are processed at the 6 connecting end faces, and 6 rotating shafts are processed, or 6 connection buckles are processed through each surface of the wrench body 1, and there are 12 in total on the two surfaces Connect the buckle to connect the 6 separate parts of the fixed wrench body. The design facilitates reducing the space required for wrench use.

In the above technical solution, the arrangement of the small jaws, middle jaws, and large jaws of the jaws is symmetrical to the center of the circle, or symmetrical to the diameter of the circle, or arranged on the circumference of the circular wrench according to the size from small to large.

In the above-mentioned technical solutions, any one of the methods of using a household round wrench is characterized in that the operation steps are as follows: according to the size of the nut, select a jaw of a suitable size, block the nut that needs to be twisted, and use Hold the center handle hole and turn the wrench body to tighten or loosen the nut; if the space used is narrow, first find a suitable size jaw, fold the wrench body into an angle according to the semicircle where the jaw is located, and then put the selected suitable jaw Hold the nut that needs to be screwed, and hold the center handle hole with your hand to turn the wrench body to tighten or loosen the nut. Or remove the movable parts of the rest of the wrench body by connecting the buckle, and only use this part of the wrench body with a suitable jaw, clamp the suitable jaw to the nut that needs to be twisted, and hold the center handle hole with your hand to rotate The wrench body tightens or loosens the nut.

The technical features of the invention are simple, convenient and professional. Compared with the existing long-handle wrench, the present invention has the following beneficial effects: (1) The manufacture is convenient and simple, and the cost is low. (2) The appearance is small and beautiful, saving time and effort, and easy to carry. (3) The design of the large circular center hole facilitates the carrying of wrenches of the present invention with different diameters and sizes, or different jaw opening sizes of different specifications.
