SUMMERY OF THE UTILITY MODEL

The utility model provides a dual-purpose lathe wrench, which replaces the currently used telescopic piece with a magnetic type mode to stretch parts, avoids rusting failure caused by the increase of the use time of a spring and is simpler and more convenient to operate.

The utility model provides a dual-purpose spanner of lathe, includes sliding sleeve, spanner body and hand (hold), the spanner body cup joints in the sliding sleeve, the hand (hold) is installed in spanner body top, the spanner body with be equipped with the locating part on the sliding sleeve, be equipped with first magnetism on the spanner body and inhale the piece, be equipped with second magnetism in the hand (hold) and inhale the piece.

Preferably, the outer surface of the wrench body is provided with a window hole for observing the condition of the wrench body.

Preferably, the handle is provided with a magnetic attraction mark.

Preferably, the wrench body comprises a combining part, and the bottom of the combining part is provided with a slot.

Preferably, a gap is arranged between the limiting piece and the wrench body.

Preferably, the surface of the limiting piece is provided with foam cotton.

Compared with the prior art, after the structure is adopted, the inconvenience influence caused by the use of the spring is reduced, the phenomenon that the rusty clamp is broken down is avoided, the use is easier, and the service life is further prolonged.

Detailed Description

The utility model is further described below with reference to fig. 1-3.

The utility model provides a dual-purpose spanner of lathe, includes sliding sleeve 1, spanner body 2 and hand (hold) 3, spanner body 2 cup joints in sliding sleeve 1, hand (hold) 3 is installed on 2 tops of spanner body, spanner body 2 with be equipped with locating part 4 on the sliding sleeve 1, be equipped with first magnetism on spanner body 2 and inhale piece 21, it inhales piece 31 to be equipped with the second magnetism in the hand (hold) 3.

More specifically, in the present invention, in order to replace the spring to make the device generate the function of the extension and contraction of the parts, the wrench body 2 is provided with the first magnetic member 21, the handle 3 is provided with the second magnetic member 31, the wrench body 2 and the handle 3 are both provided with the magnet, and at the same time, in order to limit the displacement of the magnet and protect the magnet, the wrench body 2 and the sliding sleeve 1 are both provided with the limiting part 4, the surface of the limiting part 4 is provided with foam cotton, the buffering effect is achieved when the first magnetic attraction part 21 collides with the limiting part 4, the service life is prolonged, the limiting part 4 not only limits the displacement, but also requires the minimum influence on the first magnetic attraction part 21 and the second magnetic attraction part 31, therefore, a gap 77 exists between the limiting member 4 and the sliding sleeve 1, and between the limiting member 4 and the wrench body 2, the gap 77 is provided to allow the magnetic flux to pass through for the mutual influence between the first magnetic member 21 and the second magnetic member 31.

The wrench body 2 comprises a combining part 212, the combining part 212 is a connecting part where the wrench body 2 and the handle 3 are located, a slot 211 is formed in the bottom of the combining part 212, and the magnetic attraction piece 31 on the handle 3 is better combined with the magnetic attraction piece on the wrench body 2, so that the magnetic flux is increased.

Furthermore, in the utility model, in order to improve the use experience of an operator, a window hole 6 for observing the condition of the wrench body 2 is arranged on the outer surface of the wrench body 2, the magnetic attraction mark 5 is arranged on the handle 3, and the magnetic attraction mark 5 is red.

The working principle of the utility model is as follows: it should be noted that the present invention works by using the principle of mutual repulsion of like poles and attraction of opposite poles, that is, the first magnetic attraction member 21 and the second magnetic attraction member 31 are required to be assembled into opposite poles when being installed, and at the same time, because the wrench body 2 needs to be extended and retracted by the handle 3, the wrench body 2 can slide relatively by clearance fit with the sliding sleeve 1, when the wrench body 2 needs to be extended, the first magnetic attraction member 21 and the second magnetic attraction member 31 are kept in an opposite pole state, when the wrench body 2 needs to be retracted, the handle 3 is rotated to adjust the second magnetic attraction member 31, the magnetic pole of the first magnetic attraction member 21 is changed to be the same as the magnetic pole of the second magnetic attraction member 31, it should be noted that the second magnetic attraction member 31 comprises two magnetic attraction members, one magnetic attraction member is the same as the magnetic pole of the second magnetic attraction member 31, the other magnetic pole is opposite to the magnetic pole of the second magnetic attraction member, and the operator is reminded by the magnetic attraction mark 5 on the handle 3, when the handle 3 is rotated, when a red mark is seen from the window hole 6, the heteropolar state of the first magnetic attraction piece 21 and the second magnetic attraction piece 31 is adjusted, at the moment, the wrench body 2 is stretched downwards, the chuck can be assembled and disassembled, when the use is finished, the direction of the rotating handle 3 is adjusted, after the red mark disappears, the wrench body 2 can be seen to return to the sliding sleeve 1, at the moment, the chuck is automatically separated, the sleeve wrench is prevented from being omitted on the chuck, when a tool rest tool needs to be disassembled, the device is directly sleeved, the first magnetic attraction piece 21 and the second magnetic attraction piece 31 in the tool rest device are made of strong magnetic materials, the magnetic force is increased, and the better use performance is obtained.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
