Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

In the description of the present invention, it should be noted that the terms "inside", "below", and the like refer to the orientation or positional relationship based on the drawings, or the orientation or positional relationship that the utility model product is used to usually place, are only used for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Example one

With reference to fig. 1-3, a pry head 11 is fixedly arranged at the left end of a pry bar outer rod 10, the pry head 11 can be made of high-strength tool steel and can attack and enter a thin steel plate, for example, a hole is forcibly formed in a security door to pry the security door in a security door gap, a handle 14 is fixedly arranged on the upper side wall of the pry bar outer rod 10, an inner cavity 12 is arranged in the pry bar outer rod 10, an inner pry bar 13 is slidably arranged in the inner cavity 12, and a positioning sleeve 15 is fixedly arranged on the inner pry bar 13.

When the crowbar is used, the inner rod 13 of the crowbar is contracted in the inner cavity 12 at ordinary times, when a crowbar object needs to be pried, the inner rod 13 of the crowbar is firstly drawn out within a few seconds, then the other end of the inner rod 13 of the crowbar is turned to be inserted into the inner cavity 12, and the positioning sleeve 15 is used for clamping, so that the crowbar is prolonged and used as a prying weight. In other words, if the same heavy object is pried, the tool is lighter than the traditional crowbar, thereby reducing the burden of the user and saving more labor.

When the anti-theft door and window is broken and disassembled, the inner crowbar rod 13 is pulled out to the position as large as possible from the outer crowbar rod 10 and does not fall off, then the inner crowbar rod 13 is beaten out leftwards with force, the inner crowbar rod 13 impacts the outer crowbar rod 10 to force the crowbar head 11 to impact leftwards, safety and reliability are realized, people are not injured, the speed can be increased, and larger explosive force is generated; meanwhile, the moving stroke is long, strong impact force is generated, so that the door and window can be broken and disassembled, the operation is simple and convenient, the accurate continuous attack to one part can be realized, compared with the traditional long crowbar, the attack points can be more accurate and uniform, the door and window can be accurately broken and disassembled, an iron hammer is not required to be used for knocking and attacking from the side surface, the occurrence of safety accidents is reduced, and the door and window is more suitable for some environments which cannot be unfolded.

When in emergency rescue and disaster relief, the crowbars cannot extend into the supporting points under some heavy objects, so that the crowbar head 11 can be firstly abutted against a small gap, then the impact action is repeated, the crowbars are tapped into the gap, the inner bar 13 of the crowbars is drawn out, the other end of the inner bar 13 of the crowbars is inserted into the inner cavity 12 by turning around, the positioning sleeve 15 is used for clamping, the length of the crowbars is prolonged, and lever prying is completed.

Example two

With reference to fig. 4, on the basis of the first embodiment, a handle sliding groove 17 is formed in the upper side of the crowbar outer rod 10, a handle 14 is slidably mounted on the handle sliding groove 17, and a handle spring 18 is connected between the right side wall of the handle 14 and the right side wall of the handle sliding groove 17.

When attacking the use, portable handle 14 can reduce and attack the shock and the injury that the impact force brought the hand, comfort level and security when improving the use.

EXAMPLE III

Combine accompanying drawing 5, on the basis of embodiment one, seted up thread groove 16 on the position sleeve 15 is close to the short terminal surface of pole 13 in the crowbar, set up the screw thread that can mutually support with thread groove 16 at crowbar outer lever 10 right-hand member face, when needs extension crowbar length, can insert pole 13 back in the crowbar through turning round, rotatory make position sleeve 15 and the outer lever 10 right-hand member of crowbar firmly lock, the extension crowbar, when guaranteeing to carry out the lever crow-up action, the rigidity and the bending resistance degree of crowbar.

Example four

With reference to fig. 6-8, on the basis of the first embodiment, a plurality of circles of threads are arranged at the left end of the crowbar outer rod 10, the crow head 11 is replaced with a detachable taper crow head 19 which can be matched with the threads at the left end of the crowbar outer rod 10, the detachable taper crow head 19 is conical, or the detachable taper crow head 19 is replaced with an attack crow head 20 matched with the left end of the crowbar outer rod 10 according to the use condition, the attack crow head 20 is conical, a serrated clamping block is arranged on a conical ring wall on the attack crow head 20, or the detachable taper crow head 19 is replaced with a lever crow head 21 matched with the left end of the crowbar outer rod 10 according to the use condition, and the lever crow head 21 is L-shaped.

When the tapping prying head 20 can be selectively installed during tapping use, the steel sheet can be broken and removed while the breaking and removing gap is enlarged, meanwhile, the tapping prying head 20 can be prevented from sliding out, and when the tapping prying head is used as a conventional pry, the lever prying head 21 can be installed for nail pulling and used as a lever.

EXAMPLE five

With reference to fig. 9-11, on the basis of the first embodiment, a flat pry head 22 is fixedly welded to an outer wall of an end of the pry bar outer rod 10 away from the positioning sleeve 15, and an outer diameter of the positioning sleeve 15 is the same as an outer diameter of the pry bar outer rod 10.

The crowbar is convenient to produce, the flat crow head 22 and the locating sleeve 15 are fixed by welding, the processing is rapid and convenient, and the strength is high. And the outer diameter of the positioning sleeve 15 is set to be the same as that of the crowbar outer rod 10, so that the crowbar is more convenient to carry as a whole and is more convenient to place when not in use. The flat pry head 22 can be adapted to the case where the slit edge is turned up or the like.

EXAMPLE six

With reference to fig. 12-14, in the fifth embodiment, a flat slot 24 is formed in an outer wall of an end of the crowbar outer bar 10 away from the positioning sleeve 15, and the flat crowbar 22 is inserted into the flat slot 24 and then welded and fixed to the crowbar outer bar 10.

Similar to the fifth embodiment, the crowbar of the sixth embodiment is easy to manufacture, and after the flat slot 24 is formed, the flat crowbar head 22 can be easily positioned and welded in the flat slot 24 during machining. And the arrangement of the flat-mouth groove 24 can improve the strength of the whole crowbar.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
