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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a telescopic crowbar, including

main loop bar

1, 1 one end of main loop bar is provided with flat tip 2, the inside of main loop bar 1 is provided with piston guide rail 7, piston guide rail 7 run through the other end of main loop bar 1 and communicate with the outside, the inside of piston guide rail 7 is provided with telescopic link 3, the one end of telescopic link 3 is provided with restriction slide bar 6, restriction slide bar 6 and piston guide rail 7 sliding connection, the other end of telescopic link 3 extends to the opening outside of piston guide rail 7, and the other end of telescopic link 3 is fixed and is provided with reinforced column 4, reinforced column 4's top is provided with round-head hammer 5, in order to use as the hammer.

In this embodiment, preferably, the telescopic rod 3, the reinforcing column 4 and the round-head hammer 5 are of an integrated structure, so as to ensure the overall strength.
