Description

A combination wrench

technical field

The utility model relates to a hand tool, in particular to a combined wrench.

Background technique

In hand tools, the socket and the open-end wrench are independent tools, which are usually placed separately. For example, the Chinese patent authorization announcement number: CN 2223173 discloses a plum blossom wrench, which consists of a handle, a wrench head, an upper wrench body, and a lower wrench. body composition. The upper contact surface of the upper wrench body in the wrench head is a downwardly protruding arc surface, and the lower contact surface of the lower wrench body is an upwardly protruding arc surface. The side of the opening in the wrench near the handle has an inner upper contact surface and an inner lower contact surface. The upper contact surface, the inner lower contact surface and the lower contact surface are all connected by a quincunx-shaped notch. The included angle between the inner upper contact surface and the inner lower contact surface is 120 degrees. When installing parts or performing maintenance, it is often encountered that it is inconvenient to use an ordinary open-end wrench. At this time, the user needs to switch the socket and the wrench back and forth, which is inconvenient to use, wastes time, and reduces production efficiency.

Utility model content

The utility model aims at overcoming the disadvantages that the existing wrench and the sleeve are placed separately and are inconvenient to switch back and forth, and provides a combined wrench which is combined with the wrench and the sleeve and is more convenient to use.

In order to achieve the above object, the utility model adopts the following technical solutions:

A combined wrench of the utility model includes a wrench body and a handle, the wrench body is provided with an upper wrench and a lower wrench, and the upper wrench, the lower wrench and the wrench body form a notch, the said A sleeve is provided on the surface of the wrench body close to the bottom of the notch, and the sleeve is detachably connected to the wrench body. When installing parts or performing maintenance, the bolt or nut can be directly clamped by the upper wrench and the lower wrench, and the handle can be used to tighten or loosen the operation. When encountering some special positions where it is inconvenient to work with an open-end wrench, such as a bolt hole located in a recessed position on the workpiece surface, when the open-end wrench cannot be used for tightening operation, you can switch to the sleeve for operation, thereby improving production. efficiency. In addition, the sleeve can also be replaced. For bolts or nuts of different sizes, the corresponding sleeve can be selected to replace the original sleeve so as to adapt to it, thus expanding the scope of application of the wrench.

Preferably, the sleeve includes a square pin body and a body provided with a sleeve hole, and the wrench body is provided with a positioning hole matching the pin body. Insert the pin body of the sleeve into the positioning hole on the wrench body to complete the positioning of the sleeve. The pin body is square, which limits the rotational freedom of the sleeve, so that the sleeve can rotate synchronously with the wrench.

Preferably, the sleeve hole is provided with a magnet block embedded in the bottom surface of the sleeve hole. In this way, when the bolt or nut is put into the sleeve hole of the sleeve, the magnet block is used to attract the bolt or nut, so as to facilitate the transportation of the bolt or nut to an area where the position is relatively concealed and the installation is relatively difficult, so as to prevent it from falling.

Preferably, the pin body is provided with a small hole, a ball is provided in the small hole, and a return spring is provided between the ball and the small hole. When positioning the sleeve, when the pin body is first inserted into the positioning hole, the ball moves inwardly under the pressure of the side wall of the positioning hole, and at the same time compresses the return spring. When the pin body is completely inserted into the positioning hole, the head of the pin body Going out from the other side of the wrench body, the balls are just exposed outside the wrench body. At this moment, the ball pops up under the action of the back-moving spring, thereby playing a position-limiting effect on the sleeve, and the sleeve is difficult to separate from the wrench body.

Preferably, the edges of the upper wrench, the lower wrench, the wrench body and the handle are all provided with flanges perpendicular to the plane where the handle is located. The flange increases the contact area between the handle and the human hand, reduces the pressure on the hand, and makes it more comfortable to use. In addition, the thickness of the main part of the handle can be appropriately reduced, thereby reducing the use of materials and saving manufacturing costs.

Preferably, the end of the handle away from the wrench body is provided with a hanging hole. It is convenient to hang and store the tools after use.

Therefore, the utility model has the following beneficial effects: (1) the combination of the open-end wrench and the sleeve makes it more convenient and quick to use; (2) the sleeve can be replaced and has high applicability.

In the figure, wrench body 1, sleeve 2, body 2a, sleeve hole 2b, pin body 2c, small hole 2d, handle 3, flange 3a, hanging hole 4, lower wrench 5, notch 6, upper wrench 7. Magnet block 21, ball 22, return spring 23.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

In the embodiment shown in Figure 1, a combined wrench includes an open-end wrench part and a sleeve 2, wherein the open-end wrench part is composed of a wrench body 1 and a handle 3, and the upper wrench 7, the lower wrench The head 5 and the wrench body form a notch 6, wherein the upper wrench head and the lower wrench head are the side walls of the notch respectively, and the bottom surface of the notch is on the wrench body. The sleeve is arranged on the wrench body, and is close to the bottom of the notch. The sleeve is composed of a body 2a and a pin body 2c. The pin fits to mount the socket on the wrench body. A small hole 2d is also arranged on the pin body, and a return spring 23 is arranged in the small hole, and a ball 22 is connected to the other end of the return spring. In addition, a magnet block 21 is arranged in the casing hole of the sleeve, and the magnet block is embedded in the bottom surface of the casing hole for attracting bolts or nuts. A flange 3a is provided on the edge of the handle, and the flange is perpendicular to the surface of the handle, which increases the contact area with the palm and improves the feeling of use. At one end of the handle away from the wrench body, a hanging hole 4 is provided, which is convenient for hanging and storing.

When installing parts or repairing, clamp the bolt or nut through the notches formed by the upper wrench, the lower wrench and the wrench body, and then shake the handle to tighten or loosen. When it is inconvenient to work with an open-end wrench, a sleeve can be used for operation. The sleeve can also be replaced according to the size of the bolt or nut, and the operation can be continued by selecting the corresponding sleeve to replace the original sleeve.
