Problems solved by technology

However, the connection structure between the wrench head and the handle of this type of wrench is relatively complicated, resulting in high cost of this type of wrench
At the same time, after the wrench head and the handle are connected, the two are vertical, which limits the scope of application of the wrench to a certain extent

Embodiment Construction

[0010] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0011] Examples, see figure 1 Shown: a combined wrench, including a handle 10 and a wrench 20 . The end surface of the upper end 11 of the handle 10 is provided with an end groove 111 . Meanwhile, the wrench 20 includes a die 21 and a plug 22 , and the plug 22 matches the end groove 111 . For example, the cross-section of the outside of the plug 22 is the same as the cross-section of the inner cavity of the end groove 111 . Of course, the cross section is non-circular such as ellipse and polygon. In this way, the plug 22 can be inserted into the end slot 111 and the plug 22 can be prevented from rotating. Of course, the die 21 can have various cross-sectional shapes, such as a regular hexagon and a quincunx shape. At this time, the cross section of the lower end 12 is a regular polygon, which is convenient f...

Abstract

The invention discloses a combined type wrench, comprising a handle and a wrench head, wherein an end groove is arranged on the end face of the upper end of the handle and the cross section of the lower end of the handle is in a polygon shape; and meanwhile, the wrench head comprises a wrench tooth and an inserting head; and the inserting head is matched with the end groove. Optimally, the cross section of the upper end is in the polygon shape; and meanwhile, the edge side face of the lower end is provided with an edge groove and the edge groove is matched with the inserting head. The combined type wrench has the advantages that a connecting structure of the wrench head and the handle is simple so that the preparation cost of the wrench is lower; and the angle of the wrench head and the handle is adjustable, so that the applicable range is wider.

Description

technical field [0001] The invention relates to the technical field of tools, in particular to a combined wrench. Background technique [0002] There are many kinds of wrenches, which are indispensable tools in machining and daily life. Generally, the wrenches all include a handle, the end of the handle is fixed with a wrench head, and the wrench head is provided with dies, which can be in various styles such as regular hexagons and quincunx shapes. Now there are also wrenches with separate handles and wrench heads, so that the multi-purpose purpose of one wrench (wrench) can be achieved by replacing the wrench head without changing the handle. However, the connection structure between the wrench head and the handle of this type of wrench is relatively complicated, resulting in high cost of this type of wrench. Simultaneously, after the wrench head and the handle are connected, the two are vertical, thereby limiting the scope of application of the wrench to a certain exten...
