[Prior art]

 Socket wrenches are one of the important tools and their use is wide and diverse. The use of socket wrenches in households has also become widespread, and along with this, the type and structure of the wrench have been improved, and the wrench has been diversified. Its structure is simpler and more convenient for attaching and detaching screw parts, making it easier to operate. However, when a socket is combined with a common wrench, both of them exhibit a fixed operation form (see FIG. 1), and the internal position or the skewed part does not come into contact with the threaded parts linearly. Very inconvenient to operate. Although there are some that use a universal joint to attach and detach screw parts, such circumscribed parts are not in a desirable form for use or joining. Since it has a problem in use, it needs to be improved.

【Example】

 2 to 6 show the structure of a plurality of embodiments of the present invention, but these are provided for explanation and do not limit the claims of the present invention. As shown in FIGS. 2 to 4, the present invention includes a wrench 1 and a socket 2, and has a tooth portion 111 annularly disposed on an inner side wall of a holding portion 11 at one end of the wrench 1. The locking shaft 22 of the socket 2 can be inserted and locked into the socket 11.

The socket 2 is provided with a locking shaft 22 having an outer surface formed by an arc surface protruding from an upper end of a socket body 21, a locking portion 23 provided on an inner edge of the locking shaft 22, and an outer surface. One conical surface is formed by being gradually reduced inward from the edge, and a locking tooth 221 is provided on the outer conical surface in a ring shape. 1 and a lip 24 of an appropriate length is formed at a contact portion of the locking shaft 22 with the holding portion 11, and the lip 24 is just the lower end inner edge of the holding portion 11 of the wrench 1. It can be fitted to the wrench to increase the stability in wrench operation.

By using the conical surface formed on the outer periphery of the locking shaft 22 of the socket 2 according to the above configuration, when the socket 2 is combined with the wrench 1 and used for attaching and detaching a screw component, depending on the situation. Thus, the combined angle of the socket 2 and the wrench 1 can be changed to multiple angles. This makes the operation of the wrench easier, more convenient and practical. In use, the fitting of the wrench 1 and the socket 2 can take two different forms of use (see FIGS. 3 and 4). FIG. 3 shows a normal fitting form of the wrench 1 and the socket 2, which is used for attaching and detaching a screw component which comes into linear contact with the socket 2. Locked to the inner edge of the lower end of the holding portion 11, the stability when turning the screw component is enhanced. FIG. 4 shows a fitting mode when a screw component having an inclined angle is turned. The locking shaft 22 of the socket 2 is fitted on the inner edge of the holding portion 11 of the wrench 1 and the locking teeth are formed. The socket 221 and the tooth portion 111 are in an engaged state, whereby the socket 2 is held at a certain angle in the holding portion 11, and the locking surface of the socket 2 contacts and engages with the inner wall of the holding portion 11. When the socket 2 is stopped, the socket 2 is adapted to turn the screw component by exhibiting an angle change in different directions when the socket 2 is put on the screw component.

In addition, the socket 2 of the present invention can be combined with a general ratchet wrench. In use, simply insert the connecting shaft (not shown) of the ratchet wrench into the socket 23 of the socket 2. Often, the means of use is the same as a general ratchet wrench. Another feature of the present invention is that it can be combined with an extension bar or a connecting head 3 for a wrench. As shown in FIGS. 5 and 6, the present invention can be combined with a wrench 1 and a general ratchet wrench. It is possible to cover the threaded parts that come into linear contact with the socket. As shown in FIG. 6, the connecting head 3 can be connected to another socket with a form inclined at a certain angle, and a pivot 32 projecting from the opposite end of the locking shaft 31 is located inside the outer end. It has a gradually reduced form, and can be connected to another socket at a certain inclination angle by the inclined pivot surface 321. Further, even when the connecting head configuration of FIG. 6 is used for a general ratchet wrench, it can be connected to a general socket at a certain inclination angle, further increasing the practical value.

The above embodiments are provided to explain the present invention, and do not limit the scope of the claims of the present invention. Modifications and alterations of details that can be easily made based on the present invention are as follows. Both belong to the claims of the present invention.

[Effect of the invention]

 The present invention provides a kind of structure of a wrench socket which can be adjusted at an angle so that when the socket is used, the socket and the wrench holder can be combined at an angle as required. The socket has a substantially inverted T-shape and has at one end a locking shaft having an arcuate surface, and the locking shaft is gradually reduced inward from the outer edge to form one cone. In addition, locking teeth arranged annularly on the outer conical surface are provided so that the locking shaft can be combined with the holding hole of the holding portion of the wrench, and the combination angle of the socket with the wrench during use is reduced. It is said that it can be adjusted to multiple angles and is convenient for wrench operation.
