In the embodiment, the connecting component 1 connects the to-be-lifted object 01 and the sliding hammer 2, so that the sliding hammer 2 can conveniently apply acting force to the to-be-lifted object 01 through the connecting component 1; the sliding hammer 2 can slide along the connecting component 1, the sliding hammer 2 is provided with a sliding limit position on the connecting component 1, when the sliding hammer 2 rapidly impacts the connecting component 1 in the direction away from the to-be-lifted object 01 at the sliding limit position, the impact force applied by the sliding hammer 2 to the connecting component 1 can be transmitted to the to-be-lifted object 01, so that the to-be-lifted object 01 and the connecting component 1 move in the direction away from the to-be-lifted object 01, and the to-be-lifted object 01 is lifted.

The extracting tool provided by the application can be used for extracting the slurry barrel end cover 013 of the high-temperature high-pressure water meter, in other words, the to-be-extracted object 01 can be the slurry barrel end cover 013 of the high-temperature high-pressure water meter.

When the extracting tool provided by the application is used for extracting the slurry cylinder end cover 013 from the slurry cylinder of the high-temperature high-pressure water meter, when the slurry cylinder end cover 013 is arranged on the slurry cylinder, an operator can connect one end of the connecting component 1 with the slurry cylinder end cover 013 and then operate the sliding hammer 2 to slide along the connecting component 1, so that the sliding hammer 2 impacts the other end of the connecting component 1 in a direction away from the slurry cylinder end cover 013, and the impact force applied by the sliding hammer 2 to the connecting component 1 drives the connecting component 1 and the slurry cylinder end cover 013 to move in a direction away from the slurry cylinder end cover 013, thereby realizing the extraction of the slurry cylinder end cover 013.

When the lifting tool provided by the application is applied to lifting operations of the high-temperature high-pressure water meter and the slurry cylinder end cover 013 thereof, the lifting tool changes the operation position and the operation mode of an operator on the slurry cylinder end cover 013; wherein, this tool that has changed the operating position of operating personnel to thick liquid barrel end cover 013 means that slide hammer 2 can be installed in the place that keeps away from thick liquid barrel end cover 013 through coupling assembling 1, no longer need connect and remove thick liquid barrel end cover 013 in the limited space near thick liquid barrel end cover 013, and this tool that has changed operating means of operating personnel to thick liquid barrel end cover 013 means that the thick liquid barrel end cover 013 is taken out in the mode of accessible slide hammer 2, and rather than adopting tools such as spanner to twist and draw thick liquid barrel end cover 013.

When the slide hammer 2 is adopted to lift the slurry cylinder end cover 013, the slide hammer 2 is easy to hold and convenient to move, and the connection state of the tool and the slurry cylinder end cover 013 is not needed to worry when the slide hammer 2 is moved, so that operators can lift the slurry cylinder end cover 013 easily and quickly, the working efficiency is effectively improved, the labor intensity is reduced, and the injury to the operators is avoided.

When the adjusting block 12 is unlocked and separated from the slide bar 11, an operator can adjust the position of the adjusting block 12 on the slide bar 11 according to the disassembly requirement of the to-be-lifted object 01, so that the sliding range of the sliding hammer 2 on the slide bar 11 is changed.

Referring to fig. 1, in some embodiments, a groove 21 into which the adjusting block 12 is inserted is formed at an end of the sliding weight 2, and the shape and size of the groove 21 are compatible with those of the sliding weight 2, so that when the sliding weight 2 and the adjusting block 12 strike each other, the adjusting block 12 is inserted into the groove 21 of the sliding weight 2, and the sliding weight 2 is prevented from sliding continuously.
