Now industrial technology is changing literally every day. In addition to the explosive growth of industrial technology, there are a variety of brands of electric tools on the market. Electric vibrating tools and corresponding devices of various brands are produced and sold by various manufacturers, they have different connection designs and have very low mutual compatibility and interchangeability.

The closest analogue of the proposed utility model is a multifunctional connecting device for an electric vibrating tool, known from the publication of utility model CN 203792297 U, IPC B25F 5/00, published on 08.27.2014, containing a connecting part for fixing in a chuck at the end of the follower a shaft of an electric vibrating tool having a central hole formed in the middle of the connecting part, and positioning holes located around the circumference of the wok g of the central hole.

In general, for installing an electric vibrating tool 2

The following two approaches are used: 1) The connecting part, rigidly attached to the chuck at the end of the driven shaft of the electric vibrating tool, is placed on the fixture. A U-shaped groove for quick installation is formed on the connecting part. 2) The connecting part, rigidly attached to the chuck at the end of the driven shaft of the electric vibrating tool, is formed on the device. A circular central hole is formed in the middle of the connecting part. U-groove missing. Despite the fact that the device cannot be quickly installed in the chuck at the end of the driven shaft of an electric vibrating tool, a high bond strength is achieved.

However, according to the results of a patent search, it turned out that if the first approach for quick installation was used after the second, with a firmly installed design, then the device must be replaced; the replacement is a significant inconvenience and incurs excessive costs for end users of electric vibrating tools in the form of the need to purchase devices, which entails the end user spending money, materials and resources.

Utility Model Disclosure

The technical problem solved by this utility model is to provide a connecting device, taking into account the shortcomings described in the previous part; the connecting device must be a multi-functional connecting device for an electric vibrating tool, which can be installed securely and quickly in the chuck at the end of the driven shaft of the electric vibrating tool.

the outer edge of the connecting part, respectively formed on both sides of the device. Between the two grooves, a specially provided zone with a recess is formed, allowing destruction. The grooves connected to the Central hole and the outer edge of the connecting part, respectively, are formed on both sides of the device. Between the two grooves, a specially provided zone with a recess is formed, allowing destruction. The fixture can be firmly mounted in the chuck at the end of the driven shaft of an electric vibrating tool.

When the fixture needs to be fastened quickly and connected to the chuck at the end of the driven shaft of the electric vibrating tool, the fracture-capable recess area can easily be broken along the grooves to form a recess for quick installation. The fixture does not need to be replaced, therefore one connecting fixture can be quickly and reliably installed in the chuck at the end of the driven shaft of the electric vibrating tool. The connecting device provides significant convenience and reduces the cost for end users of electric vibration tools in terms of the purchase of devices, which saves money, materials and user resources.

The technical result of this utility model is to increase the speed and reliability of the installation of the connecting device in the chuck.

In an alternative embodiment of the utility model, the grooves are located radially relative to the central hole, and a specially provided area with a recess, allowing destruction, has the shape of a sector.

In another embodiment of the utility model, the grooves are in the form of a loop-like line, and the specially formed recessed area is U-shaped.

In another embodiment of the utility model, the difference between the thickness of the connecting part and the depth of the gutters is 0.2-0.3 mm; and the width of the gutters is 1 mm.

In an alternative embodiment of the utility model, the positioning holes consist of straight grooves protruding outward from the central hole, positioning recesses are located on the outside of the central hole. Straight grooves and positional grooves are evenly distributed around the circumference around the center hole. Each two positional grooves located circumferentially from the central hole are evenly spaced between two adjacent 4

straight grooves.

The positioning holes consist of straight grooves protruding outward from the center hole and positioning grooves located outside the center hole. Straight grooves and positional grooves are evenly distributed around the circumference around the center hole. Every two positional grooves located circumferentially from the central hole are evenly spaced between two adjacent straight grooves. The connecting device can be quickly and reliably installed in the chuck at the end of the driven shaft of various types of electric vibrating tools and with different connecting interfaces.

Utility Model Implementation

Design Option I

The multifunctional connecting device for an electric vibrating tool (Figs. 1 and 2) consists of a connecting part (2) located on the device (1) and rigidly fixed in a chuck at the end of the driven shaft of the electric vibrating tool. The central hole (3) is located in the middle of the connecting part (2), and the positioning holes (4) are arranged in a circle around the central hole (3).

Slots (5) connected to the central hole (3) and the outer edge 5

the connecting part, respectively formed on both sides of the device (1); and a specially provided area with a recess (6), allowing destruction, is formed between two grooves (5).

The tool (1) is suitable for a vibrating cutting saw and a vibrating polishing blade. The vibrating cutting saw may be a vibrating band cutting saw, a sector vibrating band saw and a circular vibrating cutting saw. In the fixture for the vibrating tool in this embodiment, a vibrating band saw is used. The lower end of the vibrating band saw is a saw blade with straight teeth made of steel alloy; the upper end is a handle connected to a vibrating saw and made of steel alloy. The upper end and lower end are joined by spot welding. This tool is suitable for cutting and sawing various metals, wooden boards, fiberboards, drywall and plastic.

The grooves (5) in this design are located radially with respect to the central hole (3); a specially provided area with a recess (6), allowing destruction, has the shape of a sector.

The value of the difference between the thickness of the connecting part (2) and the depth of the grooves in this design is 0.2-0.3 mm; the width of the grooves (5) is 1 mm. Since the unedged connecting part of each groove (5) is thinner, the area between the two grooves (5) can be selectively destroyed along the grooves, while the entire connection (2) will be with a hole.

The positioning holes (4) of the utility model are straight grooves extending from the central hole, the positioning grooves are located outside the central hole. Straight grooves and positional grooves are evenly distributed around the circumference around the central hole; two positional grooves around the circumference around the central hole are evenly distributed between two adjacent straight grooves.

When using the multifunctional connecting device for an electric vibrating tool in this embodiment, the device can be quickly fixed and connected to the chucks at the ends of the driven shafts of various electric vibrating tools using the connecting part (2) and is suitable for electric vibration tools of brands such as MARKTOP, B&D, Fein, Bosch, Worx, 6

Rockwell and their analogues.
