Fig. 1 is a structural representation of the utility model.

detailed description

As shown in Figure 1, a small wrench is characterized in that it includes a replaceable head 1, a lowered cartridge holder 2, a cylindrical cartridge holder 3, a main body 4, a portable head 5, a one-way bearing 6, and a bearing holder 7, The left and right directions of the main part 4 are respectively equipped with a cylindrical cartridge card 3, the upper part of the main part 4 is equipped with a portable head 5, and a one-way bearing 6 is installed inside the main part 4, and the one-way bearing 6 passes through the bearing bracket 7 Install the bow card 2.

In this embodiment, a replaceable head 1 is installed on the lower head cartridge 2 and the cylindrical cartridge 3 .

In this embodiment, the portable head 5 is a cube structure.

In this embodiment, the six faces of the portable head 5 are provided with inner hexagonal squares of different sizes.

In this embodiment, the one-way bearing 6 is installed with the cylindrical barrel card 3 through the bearing card frame 7 .

In this embodiment, a portable head 5 is installed on the cylinder card 3 .

The working principle of the utility model is:

The replaceable head 1 can be used in conjunction with the low-head barrel clamp 2 and the cylindrical barrel clamp 3 after being installed, satisfying the flexible usability of the wrench. The one-way bearing 6 can be used in one direction when fastening the lower cartridge clamp 2 and the replaceable head 1 by utilizing its unidirectionality. The portable head 5 can be used in conjunction with the main body 4, and can also be carried around. The six sides of the portable head 5 are provided with inner hexagonal squares of different sizes to fasten different screws, which can be used in a narrow range of space. place to use. The cylindrical barrel clamp 3 can also be used in conjunction with the one-way bearing 6 to meet the flexibility of the wrench.

The utility model is generally divided into three parts, the first part is the main part 4, and secondly, a one-way bearing 6 is arranged inside to meet its fastness in a single direction; Cooperate with itself, and increase its use length in a narrow and slender space; the third part is a portable head 5, which is used in conjunction with the main body 4, and can also be used in conjunction with the cylindrical cartridge card 3, and It can be used independently, can be used in a very small space, and is convenient and portable.

The main part 4 is provided with a square groove for installing the cylindrical cartridge card 3 and the portable head 5. The mounting end of the cylindrical cartridge card 3, the portable head 5 and the main part 4 is a square head, and the square groove of the main part 4 Cooperate. The inside of the other end of the cylindrical barrel card 3 is also provided with a square groove, which can be used to install the portable head 5 or continue to install the next cylindrical barrel card 3 to extend the length.

All in all, the utility model can be freely adjusted and used in different space ranges, lengthened or single-use, flexible and convenient to use.

The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present utility model without creative efforts.
