In order to achieve the above purpose, the present invention is realized by the following technical solutions: a socket wrench with a telescopic socket head, the structure of which comprises: the telescopic sleeve, the spanner body, anti-skidding line, the end is portable to be joined in marriage in the telescopic sleeve in one side, be equipped with anti-skidding line on the spanner body, spanner body both sides all are equipped with the telescopic sleeve, the telescopic sleeve still includes compression spring, the lifter plate, spacing spring, the pull rod, the kicking block, the draw-in groove, the protective housing, the compression spring upper end is connected with the lifter plate lower extreme, the embedding of end lower extreme is installed in the protective housing, the end lower extreme is connected with the lifter plate, in the draw-in groove is joined in marriage to kicking block one side, draw-in groove and end structure as an organic whole, spacing spring one side is connected with the kicking block, spacing spring opposite side is connected with the inner wall of protective housing.

Preferably, the top blocks are provided in two and mounted in the protective case.

Preferably, the clamping grooves are two in number and are arranged on the end head.

Preferably, the top block and the clamping groove both adopt a circular truncated cone-shaped structure.

Preferably, both sides of the pull rod are provided with limiting springs.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: through the pull rod on the flexible cover of pulling out simultaneously, deformation takes place for spacing spring, make the kicking block follow the pull rod and remove, until breaking away from the draw-in groove, just it disappears spacing to the end, cause compression spring to lose spacing and the reconversion, the lifter plate just moves down, thereby take the end to move down, the end most retracts into the protective housing, only partial department exposes outside, when the end is pulled out to needs, through the partial department that exposes with the end pull-up, make the kicking block fall into the draw-in groove again can, the device can take the kicking block to break away from the draw-in groove through the pulling pull rod, make the end can retract into in the protective housing, cause and be difficult for receiving colliding with and damaging at transport or carrying in-process end, effectively avoid the end to contact too much time with the air and rust simultaneously.
