[0029] The technical solution is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the content of the present utility model.

[0030] Example 1

[0031] In order to solve the pain point of breaking automobile laminated glass during law enforcement, rescue and other processes, the utility model provides a special breaking tool with the functions of breaking glass, breaking locks, cutting seat belts and the like.

[0032] like Figure 1 As shown, a multifunctional rescue tool for vehicle rescue, the rescue tool comprises:

[0033] The demolition hammer 1 has a hollow handle 11 with an opening at the lower end, and a hammer head including a cutting portion 12 and a fulcrum portion 13;

[0034] The lock picking knife 2 has a knife head 22 placed in the hammer handle 11, and the knife handle 21 is detachably fixed to the opening via a snap-fit ​​structure 211;

[0035] The cutting knife 3 is fixed to the upper end of the hammer handle 11 and is located below the hammer head.

[0036] The cutting portion 12 and the fulcrum portion 13 are both located on one side of the hammer head; the other side of the hammer head is a hammering end 14; and the fulcrum portion 13 is connected to the hammer handle 11.

[0037] The cross section of the hammer handle 11 is an ellipse, and the major axis direction of the ellipse is the same as the length direction of the hammer head.

[0038] like Figure 2-4 As shown, the cutting portion 12 includes: a jaw segment 121 connected to the fulcrum portion 13 at one end, an expansion segment 122 connected to the jaw segment 121, and a cutting segment 123 connected to the expansion segment 122; the jaw segment 121 and the fulcrum portion 13 form a V-shaped jaw; the jaw segment 121 has a large-angle cutting edge 1201 of 60°-150° on the jaw side for cutting laminated glass.

[0039] The cutting section 123 is a diamond-shaped cone.

[0040] The expansion section 122 includes a polygonal pyramid.

[0041] The fulcrum portion 13 includes a cantilever 131 connected to the hammer handle 11 and an anti-slip flange 132 connected to an end of the cantilever 131 .

[0042] The cutter head 22 includes a wedge-shaped intrusion section 221 .

[0043] The cutting knife 3 comprises a V-shaped blade.

[0044] A fixing seat 111 for fixing and protecting the cutting knife 3 is provided at the upper end of the hammer handle 11 .
