SUMMERY OF THE UTILITY MODEL

The utility model discloses a general tapping spanner with adjustable it is various to current tapping spanner is the most, and the problem that special tapping structure need whole change when the screw tap produces the problem, has designed a spatial structure and has adapted the tapping spanner of different models, only needs the twist grip to switch the tapping screw tap size, and tapping in-process axle center does benefit to the user operation for spanner focus position all the time.

A special tap wrench, comprising: the wrench block is in a cuboid shape; the first hole is arranged in the center of the top surface of the wrench block; the second hole is formed in the center of the front face of the wrench block; the third hole is arranged in the center of the bottom surface of the wrench block; the fourth hole is formed in the center of the back of the wrench block; the wrench comprises a wrench block, a first wrench handle and a second wrench handle, wherein the number of the wrench handles is two, the first wrench handle is arranged on the left side surface of the wrench block, and the second wrench handle is arranged on the right side surface of the wrench block and is fixedly connected with the wrench block; and a magnetic block groove is formed in the center of the first hole and used for mounting a magnet.

The hole of seting up four installation screw tap tails on the spanner piece is used for installing the screw tap of different sizes, can use simultaneously also can the exclusive use, can be adsorbed when the screw tap afterbody and the inside magnet contact of spanner piece.

Preferably, the wrench block is a rectangular parallelepiped with a square cross section and equal height and width.

Preferably, the first hole, the second hole, the third hole and the fourth hole are square holes, and the depth of the holes is 1/3 of the height of the wrench block; the size of the first hole to the size of the fourth hole are reduced in sequence.

A depth of 1/3 is advantageous to help uniform the tap tail distance to ensure that the tap tail has access to the internal magnets.

Preferably, the upper side surface and the lower side surface of the magnet are provided with handle-shaped structures which are matched with the magnetic block grooves.

Preferably, the two sides of the magnetic block groove in a shape of Chinese character 'Zhong' are communicated with the bottoms of the second hole and the fourth hole, the front surface of the magnetic block groove is communicated with the bottom of the first hole, and the back surface of the magnetic block groove is communicated with the bottom of the third hole.

The beneficial effects of the utility model reside in that: simple structure is practical convenient, only needs to rotate the spanner handle and can switch tapping screw tap, convenient operation to built-in magnet can adsorb the screw tap and prevent that the screw tap from dropping.

Detailed Description

The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.

Example 1

As shown in fig. 1, 2, 3, 4 and 5, the special tap wrench includes:

the wrench block 1 is in a cuboid shape; the first hole 3 is arranged in the center of the top surface of the wrench block 1; the second hole 5 is arranged in the center of the front face of the wrench block 1; a third hole 6 arranged at the center of the bottom surface of the wrench block 1; a fourth hole 7 arranged at the center of the back of the wrench block 1; spanner handle 2 totally two, the first setting is at 1 left surface of spanner piece, and the second setting is at 1 right flank of spanner piece, all with 1 fixed connection of spanner piece.

The hole of seting up four installation screw tap tails on spanner piece 1 is used for installing the screw tap of different sizes, can use simultaneously also can the exclusive use, can be adsorbed when the screw tap tail with the contact of 1 inside magnet 4 of spanner piece.
