FIG. 2 is a schematic top view of the present invention;

fig. 3 is an enlarged structure view of the folding part of the wrench rod.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

Example 1: as shown in fig. 1-3, a four-hole wrench comprises a wrench rod 1 and wrench heads 2, two ends of the wrench rod 1 are fixedly connected with two wrench heads 2 with different specifications, two ends of each wrench head 2 in the length direction are provided with two quincunx sleeves 3 with different specifications, and the wrench rod 1 is of a folding structure and is folded towards the length direction of the wrench head 2.

Preferably, above-mentioned spanner pole 1 includes first section pole 4 and second section pole 5, the folding end of first section pole 4 is provided with U type breach 6, the folding end of second section pole 5 is provided with protruding type head 7, protruding type head 7 is embedded into U type breach 6 and is adopted pivot 8 to connect, pivot and 6 fixed connection of U type breach, adopt the beta structure of ears and monaural, moreover, the steam generator is simple in structure, the connection is reliable, the rigidity is good, U type breach 6 and protruding type head 7 tip all set the same cylinder structure, be convenient for rotate, avoid producing between U type breach 6 and the protruding type head 7 and interfere.
