Example  1. Multi-purpose Ratchet wrench

The present invention will be described with reference to the accompanying drawings.

First, FIG. 1 shows a configuration of a multi-purpose ratchet wrench according to the present invention.

1 of the accompanying drawings includes a ratchet wrench 1, a thermal member 2 and a hexagonal wrench 3. The ratchet wrench 1 shown in Fig.

The ratchet wrench 1 is constituted by a ratchet part 11, a knob part 12 and a spanner part 13. The knob part 12 is configured to be grasped by a user.

The wrench portion 13 is formed at one end of the handle portion 12, and can perform a normal spanner function.

The ratchet portion 11 is formed on the other end of the handle portion 12 and includes a ratchet wheel 111. The ratchet wheel 111 is configured to pass through the ratchet portion 11 from one flat surface to the other do.

Therefore, the user can use the ratchet wrench 1 in both directions.

That is, the ratchet wheel 1 is configured so that the ratchet wheel 111 can be rotated only in one direction by a configuration described later, and is not rotated when it tries to rotate in the opposite direction.

In other words, it is possible to tighten the bolt or the like by forcibly turning in a direction in which the ratchet wheel 1 is not rotated. When the ratchet wrench 1 is to be released again, it may be possible to rotate the ratchet wrench 1 in the opposite direction.

Hereinafter, the ratchet wheel 111 will be described with reference to FIG. 2 of the accompanying drawings.

FIG. 2 shows the construction of a ratchet wheel in a multipurpose ratchet wrench according to the present invention.

2 of the accompanying drawings, the ratchet wheel 111 may mainly include a wheel shaft 1111, a gear 1112, a stopper 1113, a stopper shaft 1113a, and an intermittent member 1114. [

That is, in the ratchet wheel 111 configured to penetrate the ratchet part 11, the wheel shaft 1111 is formed in a circular shape along the inner surface of the ratchet wheel 111, and the gear 1112 is formed on the outer peripheral surface of the wheel shaft 1111, .

A plurality of protrusions protrude from the inner circumferential surface of the wheel shaft 1111 at regular intervals. When the bolt is inserted into the ratchet wheel 111 in various angular shapes, all shapes can be fixed.

The gear 1112 is configured such that one surface thereof is inclined in one direction and the other surface thereof is inclined in the same direction as the one surface and inclined more than the inclination angle of the one surface.

A stopper 1113 is provided at one side of the inner side of the ratchet part 11 so that one end of the stopper 1113 comes into contact with the gear 1112 and rotates about the stopper shaft 1113a provided at the opposite end. .

An intermittent member 1114 can be formed at one side of the inside of the ratchet section 11, and the intermittent member 1114 functions to intermittently rotate the stopper 1113 in only one direction.

2, when the ratchet wheel 111 rotates in one direction, it is rotatable. When the ratchet wheel 111 is to be rotated in two directions, the stopper 1113 is interrupted by the intermittent member 1114, And the gear 1112 is caught by the stopper 1113 in an oblique direction so that the ratchet wheel 111 can not be rotated as a result.

Hereinafter, the connecting member 2 will be described with reference to Fig.

FIG. 3 shows a configuration of a connecting member according to a first embodiment of the multipurpose ratchet wrench according to the present invention.

The connecting member 2 is connected to the hexagonal wrench 3 so that a normal bolt can be inserted while nothing is inserted into the ratchet portion 11 of the ratchet wrench 1 described above. Or a loosening operation is required, there has been a problem that a hexagonal wrench has to be separately prepared.

However, according to the present invention, since the hexagonal wrench 3 can be connected through the connecting member 2, it is possible to perform an easy operation if only the connecting member 2 and the hexagonal wrench 3 are provided.

On the other hand, the above-described hexagonal wrench 3 is only one example that is clearly specified for the purpose of clarifying understanding of the present invention. As described above, the inventor appropriately uses the concept of the term to describe its own invention in the best way. The hexagonal wrench 3 can be used in the same manner as the hexagonal wrench 3 shown in the drawing. In the hexagonal wrench 3 of the present invention, In addition, the hexagonal shape for connecting to the connecting member 2 may be the same, and the other end may be formed of a driver (straight and / or crossed) other than the hexagonal wrench, a square wrench, and a polygonal wrench.

The connecting member 2 includes a magnet, specifically, a base 21, an insertion protrusion 22, a magnet 23, and a magnet 24 in order to increase a coupling force when the ratchet wrench 1 is made of a metallic material. And includes a hexagonal wrench fixing portion 24.

Specifically, the insertion projection 22 protrudes in a hexagonal shape from one side of the base 21, and the insertion projection 22 has a concave groove formed therein, and the magnet 23 is inserted into the groove.

A hexagonal wrench fixing portion 24 having a predetermined depth is formed on the opposite surface of the base 21 so that the hexagonal wrench 3 can be inserted into the hexagonal wrench fixing portion 24.

The insertion protrusion 22 is inserted into the ratchet portion 11 of the ratchet wrench 1 so that the magnetic force of the magnet 23 is transmitted to the ratchet portion 11 of the ratchet wrench 1. [ To the surface of the insertion protrusion 22 so that the insertion protrusion 22 of the connecting member 2 can be worn by the magnetic force to the ratchet part 11 of the ratchet wrench 1. [

Of course, the magnetic force of the magnet 23 can be adjusted by the attraction force.

At this time, in the case of the above-described connecting member 2, a plurality of the hexagonal wrench fixing portions 24 may be provided in various sizes according to the diameter of the hexagonal wrench 3.

In this case, the user can select and connect the connecting member 2 according to the diameter of the hexagonal wrench 3, but it is cumbersome to selectively use the connecting member 2 after having the plurality of connecting members 2.

Therefore, the present applicant intends to propose a scheme similar to the second and third embodiments described later.

Example  2. Multi-tiered Allen wrench  Including the Government The connecting member  A multi-purpose ratchet wrench

In the following description of the second embodiment and the third embodiment, the description overlapping with the first embodiment will not be described again.

The present invention according to the second and third embodiments will be described with reference to FIG. 4 of the accompanying drawings.

4 (a) and 4 (b) illustrate a connecting member according to a second and a third embodiment of the present invention. FIG. 4 (a) (b) shows a connection member configuration of a third embodiment according to the present invention.

4A, the hexagonal wrench fixing part 24 formed on the opposite surface of the connecting member 2 on which the insertion protrusions 22 are formed may have a multi-stage structure according to the second embodiment.

The hexagonal wrench fastening portions 24 are formed to have different depths. In other words, the hexagonal wrench fastening portions are formed deepest in the case of the narrow hexagonal fastening portions, And the depth order is shallow.

At this time, the multi-step hexagonal wrench fixing part 24 is constructed so as to correspond to a predetermined diameter size of the conventional hexagonal wrench 3, so that the user can insert the hexagonal wrench 3 into the large- Therefore, it is not necessary to perform troublesome work of replacing the connecting member 2 according to the size of the hexagonal wrench 3.

However, since the hexagonal wrench fixing portion 24 having a multi-tiered depth is different, when the hexagonal wrench 3 having a large diameter is used, there is a possibility that the fixing force is weakened, and thus the proposal according to the third embodiment is proposed.

Example  3. Resizable Allen wrench  Including the Government The connecting member  A multi-purpose ratchet wrench

4 (b), the hexagonal wrench fixing part 24 is composed of a single step, and may include an elastic member 241, a fixing member 242, and a guide member 243. As shown in FIG.

Specifically, one end of the elastic member 241 is connected to one side of the inner surface of the hexagonal wrench fixing portion 24, and the fixing member 242 is connected to the opposite end of the elastic member 241. The fixing member is operated along guide members 243 protruding from both ends of each of the hexagonal wrench fixing portions, and can be adjusted and fixed according to the diameter of the hexagonal wrench.

That is, a guide member 243 protruding at a certain angle is formed on both ends of each of the hexagonal wrench fixing portions 24.

At this time, the guide member 243 is protruded higher than the point where the elastic member 241 and the fixing member 242 are connected. The fixing member 242 has a trapezoidal shape. The trapezoidal side surface of the fixing member 242 and the guide member 243 are configured to have the same angle.

The fixing member 242 is able to fix the hexagonal wrench 3 by the elastic force which is moved along the guide member 243 but the elastic member 241 tends to expand and the diameter of the hexagonal wrench 3 is Even if it is various, there is an advantage which can be accommodated all.

1 to 4, only the main points of the present invention are described. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 4 It is self-evident.
