Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a scalable crowbar of portable high tenacity, includes crow head 1, and crow head 1 rotates through the pivot to be connected with sled neck 2, and the first handle 3 of bottom fixedly connected with of sled neck 2, the bottom of first handle 3 rotate through the torsional spring pivot to be connected with second handle 4, and the bottom of second handle 4 rotates through the torsional spring pivot to be connected with third handle 5 for the handle comprises the triplex.

Specifically, as shown in fig. 1 to 3, grooves 9 are formed in the outer walls of the first handle 3 and the third handle 5 at the ends close to the rotating shaft, and a first collar 6 and a second collar 7 are respectively sleeved outside the first handle 3 and the third handle 5.

In particular, as shown in fig. 1-3, the inner diameter of the first collar 6 and the second collar 7 is equal to the outer diameter at the groove 9, such that in the collapsed state, the first collar 6 and the second collar 7 rest at the corresponding groove 9.

Specifically, as shown in fig. 1-3, rubber strip 8 has all been cup jointed to the outer wall that first handle 3, second handle 4 and third handle 5 are close to pivot department, and when the crow bar was used, first lantern ring 6 and second lantern ring 7 drew into the corresponding pivot outside to guarantee the stability of crow bar, rubber strip 8 has improved the stability of the lantern ring.
