Description

Bend and fixed hand tools

This creation is about a bendable and fixed hand tool structure with a bending angle function on the handle of the hand tool, so that a hand tool can have both a double-handed hand tool and a double-handed long hand tool, and Bend when space is limited.

When hand tools are used in actual work, they often encounter limited working space. Thus, hand tool designs that can be used under a variety of space constraints are available. For example, FIG. 1 is a patent of JP2010-284751, which discloses a wrench used in a restricted space, which is pivotally connected with a wrench using an extended handle, and can be used when the space above the nut is limited and the wrench cannot be held. Extend the wrench handle to the outside. This type of wrench uses a non-fixed pivot connection and can only be used in a bent state.

Another example is disclosed in FIG. 2, which discloses a "swing wrench" of No. 201026440, wherein the handle and the head are adjustable in relative angles, and when the space is limited, the relative angle between the handle and the head is adjusted. The drive head can be used in a small space. This conventional technique is basically a "long-handle wrench with a double drive end". When the space is limited and the long-handle wrench cannot be used, it cannot be used, and another conventional short-handle wrench must be carried.

Another FIG. 3 discloses another conventional technique, namely, the new M302435 "hand tool grip angle adjustment structure". This is a three-stage connecting wrench, which also has the function of adjusting the head and the grip, and both sides are short handles. When the space is limited and the long-handle wrench cannot be used, any one of the two sides of the wrench is used. Features a short-handle wrench. However, the three-stage wrench is not only extremely inconvenient to carry, but also too cumbersome in actual use. Since the whole wrench is composed of three grip segments, when only one of the grip segments is used, the other two grip segments have no effect and are inconvenient to use, and in fact, the space is still small and cannot be used.

Although the conventional hand tools have a bending function and can be used when the space is limited, but the wrench cannot have the functions of a long handle and a short handle, the user still needs to carry two wrenches with a long handle and a short handle. Since the hand tools such as wrenches are composed of multiple branches, which are suitable for different sizes of wrenches, a common set of eight wrenches is used as an example. If two wrenches are required, it is necessary to carry two groups. Sixteen wrenches, especially when working at heights, limit the number of tools that can be carried, which can cause extreme inconvenience to the user.

In order to solve the foregoing problems, the present invention provides a bendable and fixed hand tool structure having a first gripping lever member and a second gripping lever member. One of the two gripping lever members is a connecting end and the other end is driven. The two connecting ends are pivotally connected; the pivoting shaft can adjust the relative angle of the rods, and can be positioned after adjusting the angle.

Compared with the prior art, the creation has the functions of being used as a short handle tool and a long handle tool. The user can make a choice according to the space and the use condition, and is closer to the use requirement, and can be combined with one hand tool. The short handle, long handle and bending function saves the user the inconvenience of having to carry multiple hand tools for different space use, and can also be used as a bending hand tool.

Figure 4 is a preferred embodiment of the present invention. The hand tool of the present invention has a first gripping member (11) and a second gripping member (12). One end of the first holding rod member is a first driving end (13), and the other end is a first connecting end (20). The driving end is an open-end wrench in this embodiment. In fact, various types of driving heads can also be used. For example, a socket wrench head or a screwdriver head. One end of the second holding rod member is a second driving end (14), and the other end is a second connecting end (30). The second driving end is a closed-end wrench in this embodiment, and can actually use various forms of driving. Head, such as a socket wrench head or a screwdriver head. The first connecting end of the first holding lever and the second connecting end of the second holding lever are coupled by a fixable post (40).

In order to enable the two gripping members to have the function of a short-handle wrench alone, the first gripping lever member and the second gripping lever member each have a grip portion and have substantially the same length, that is, the pivot is located The middle of the wrench is optimal. However, the above functions can be achieved with the pivot center and the center points of the first and second driving ends as a reference, and the ratio of the length of the pivot to the driving end to the total length of the wrench is 0.4 to 0.6. When the pivot is fixed, the entire wrench can be used as a long-handle wrench.

Figure 5 is an exploded view showing the structure of the joint end and the pivot of the present invention. The first joint end has a flange (21) having a first perforation (22), the first perforation having a plurality of teeth (23) in the bore. The second connecting end (30) has an upper portion (31) and a lower portion (32). The upper portion is vertically juxtaposed with the lower portion, and a space (33) is formed between the upper and lower portions. The space (33) can accommodate the flange (21). thickness. The upper portion (31) is provided with a second perforation (34) having a plurality of teeth (35) in the hole; the lower portion (32) is provided with a through hole (36), the through hole ( 36) Concentric with the second perforation (34).

After the flange (21) of the first connecting end is inserted into the space (33) of the second connecting end, The post (40) is received in the hole of the first connecting end, the post (40) has a toothed section (41) and a column section (42), and the outer diameter of the toothed section is larger than the outer diameter of the column section (42) and the through hole (32) Inner diameter. The sprocket segment (41) is positioned when the majority of the teeth (23) of the first connecting end and the plurality of teeth (35) of the second connecting end are engaged, and when the squeegee (41) is pressed down from the majority of the teeth (35), the card is engaged. The tooth segment (41) only meshes with the first perforation (22) and does not mesh with the second perforation (34), and the first connecting end and the second connecting end are no longer engaged and fixed to form a relative rotation state. . After turning it to the desired angle, the post (40) is moved up to the clamping position and the two gripping members are fixed at the desired relative angles.

When the creation is actually used, the state shown in Fig. 4 can be used as a general long-handle double-head wrench. When the space is limited, as shown in Fig. 6, it is a plan view of a mechanical structure using bolts. The bolt head protrudes from the plane of the structure, that is, the paper surface, and the outer frame has the same height as the bolt head. To avoid bulging bolt heads hurting people. This structural design makes the space used by the wrench limited. The wrench of this creation is bent at 90 degrees. After the bolt head is inserted in the direction of the vertical paper, the first grip can be used as a short-handle wrench. The illustration shows the case where the open drive end is used. Of course, the closed drive end can also be used, that is, the function of having a double-headed short handle. In this space, only conventional short-handled wrenches can be used, and any conventional bending wrench cannot be used. However, if you carry a short-handle wrench, you still need to carry a long-handle wrench when you need a long handle. This creation has the function of short handle and long-handle wrench, which can save half of the inconvenience of carrying.

It can be seen from the preferred embodiment that none of the conventional techniques of bendable wrenches can combine the various functions of the present invention, and the present invention is more portable than any of the prior art. The above description is only a preferred embodiment, and is not intended to limit the scope of the present invention. The use case only lists one aspect. In fact, there are still many other use cases that can only be used by this creation.
