Description

Hand tools with replaceable operating parts

This creation involves the replacement of hand tools, especially a hand tool with replaceable operating parts.

There are many types of traditional hand tools, such as wrenches and screwdrivers. Known wrenches convert human power into an applied force, locking or loosening a screw joint. However, most wrenches are integrally formed. Therefore, the open-end wrench is a U-shaped structure. There is no ring body design of the torx wrench, and it also lacks the function and effect of the socket wrench or ratchet wrench.

The disadvantage is that the integrally formed wrench is suitable for metric size screw joints and cannot drive the inch size screw joints to rotate. Regardless of the metric or imperial system, the wrench only locks or loosens a single-sized screw connection. To turn most screw joints, you must bring a set of open-end wrenches, torx wrenches, socket wrenches or ratchet wrenches. Most wrenches are made of iron metal or iron alloys (such as steel, stainless steel, and steel alloys), so the whole set of wrenches is bulky and occupies a certain space, which is not easy to carry.

The traditional screwdriver is also integrally formed, one end of which is a grip, and the other end forms a working section. The working section is designed as a straight line, so it is not suitable for screws to form a plum-shaped or cross-shaped recess in the head. Because the screwdriver is also a set, the appropriate screwdriver can be selected, so the whole set of screwdrivers is not only bulky, but also occupy Huge space, not easy to carry.

Therefore, how to make hand tools easy to carry and have the function of interchangeable use of wrenches and screwdrivers has become an urgent problem to be solved in this creation.

In view of this, this creation provides new hand tools, the main purpose of which is to use the means of coupling and use the same grip to combine the operating parts of different wrenches or screwdriver functions, so as to easily carry the hand tools, and have the entire set of wrenches and screwdrivers interchangeable Function.

Due to the achievement of the above purpose, the hand tool of the present creation includes: a grip with a groove; and, a plurality of operating parts, each of the operating parts has a rod, the rod is combined with the groove, so that the grip and the Pieces together. Among them, each operating part also has a head with a locking or loosening function shape, so that the hand tool is like one of an open-end wrench, a torx wrench, a socket wrench, a ratchet wrench and a screwdriver to perform a tightening operation on a workpiece.

In this way, this creation uses the linking method of the rod and the groove, and uses the same grip to combine different operating parts, which can not only easily carry hand tools, but also obtain the function of a set of wrenches or screwdrivers through multiple heads.

In order to make the purpose, features and advantages of this creation more obvious and easy to understand, here are one or more preferred embodiments, which are described in detail in conjunction with the accompanying drawings as follows.

Figure 1 is an exploded perspective view of a preferred embodiment of the authoring hand tool.

Figure 2 is a combined cross-sectional view of a hand tool.

Fig. 3 is a cross-sectional view taken along line A-A of Fig. 2.

Fig. 1 is a perspective view illustrating the structure of a preferred embodiment of a handle tool 10, which is composed of a grip 12 and a set of operating members. The entire set of operating elements is simplified into three, defined as a first operating element 20, a second operating element 30 and a third operating element 40.

First, the first operating member 20 has a head 22 configured with a ratchet 21 having a hole 24 and a directional knob 23. The directional knob 23 controls the ratchet 21 and the head 22 to rotate in the same direction as well as Rotate each other. Therefore, the head 22 has a functional shape of a ratchet wrench.

Secondly, the first operating member 20 also has a rod 26, and the root of the rod 26 is designed to be integrated with the head 22, and the other end extends a coupling section 28. Both the rod 26 and the coupling section 28 are hexagonal bodies made of metal or alloy, and the diagonal distance of the rod 26 is greater than the diagonal distance of the coupling section 28.

As shown in FIG. 2, the grip 12 has a groove 14 with a round hole section 141 whose diameter is larger than the diagonal distance of the rod 26 or the coupling section 28. One end of the circular hole section 141 passes through the end surface of the grip 12 and the other end extends a polygonal section 142 to the bottom 143 of the groove 14. One magnet 16 is a permanent magnet which is embedded in the bottom 143 of the groove 14.

When the rod 26 passes through the round hole section 141 of the grip 12, the coupling section 28 is inserted into the polygonal section 142, and the magnetic field around the magnet 16 interacts with the coupling section 28 to produce a magnetic attraction effect. In this way, the rod 26 is combined with the groove 14 to connect the handle 12 with the first operating member 20.

Because the shape of the coupling section 28 conforms to the polygonal section 142 (see FIG. 3), the grip 12 and the first operating member 20 must not rotate with each other. However, the grip 12 can The first operating member 20 is driven to rotate around the hole 24.

Looking back at Fig. 1, the structure of the second operating member 30 is substantially the same as that of the first operating member 20. For example, the second operating member 30 is made of metal or alloy, and connects the head 32 and the coupling section 38 through the rod 36. The rod 36 and the coupling section 38 are both hexagonal, and the diagonal distance of the coupling section 38 is smaller than the diagonal distance of the rod 36.

The difference is that the head 32 is a U-shaped block, and the U-shaped block encloses a rectangular opening 34, so that the head 32 has a functional shape of an open-end wrench.

In this way, the rod 36 and the coupling section 38 are combined with the groove 14 of the grip 12, and the opening 34 of the second operating member 30 enables the hand tool 10 to function as an open-end wrench. After the second operating member 30 is removed, the groove 14 of the grip 12 is combined with the rod 26 of the first operating member 20, which is sufficient for the hand tool 10 to function as a ratchet wrench.

In other words, the head has the functional shape of a torx wrench or socket wrench, and the operating member combined with the hand tool 10 composed of the grip 12 can be used as a torx wrench or socket wrench.

In terms of construction, the third operating member 40 is the same as the first operating member 20 in that both are made of metal or alloy. Moreover, the rod 46 and the coupling section 48 are both hexagonal, and the diagonal distance of the coupling section 48 is smaller than the diagonal distance of the rod 46.

The difference is that the head 42 is also a hexagon. A neck 44 connects the head 42 to the rod 46. A working section 41 is formed on the head 42, and the coupling section 48 is at both ends of the third operating member 40. In the figure, the working section 41 is cross-shaped. When the rod 46 is inserted into the groove 14 of the grip 12, the head 42 provides the third operating member 40 with the functional shape of a screwdriver.

In some embodiments, the working section 41 may be a straight shape, a star shape, a chevron shape, or other geometric shapes.
