in the third embodiment, the third embodiment comprises a threaded hole 8, a threaded rod 801 is arranged in the threaded hole 8 in a threaded manner, a sealing gasket 802 is arranged on the outer side of the threaded rod 801, a screw cap 803 is arranged on one side of the threaded rod 801, the threaded hole 8 can provide a passage for a worker to observe the impact head 607 and the impact chamber 306, the screw cap 803 can be matched with the threaded rod 801 in a threaded manner, the sealing gasket 802 is squeezed to seal the threaded hole 8 under the action of the screw cap 803, the sealing of the impact chamber 306 is guaranteed, a worker can drive the threaded rod 801 to be matched with the threaded hole 8 in a threaded manner by rotating the screw cap 803 to screw out the threaded rod 801, the effect of opening the threaded hole 8 is realized, then the worker can directly observe the loss condition of the impact head 607 from the threaded hole 8 by irradiating the impact head 607 from the threaded hole 8 with a flashlight, thereby need not dismantle rear end cover 3 and observe, for the staff provides convenient, save staff's physical power and time.

Referring to fig. 1 and 2, a cylinder with an internal lubrication function,

the embodiment four, including the lagging 4, the inside of lagging 4 runs through movable mounting has measuring tape 402, connecting rod 403 is installed at the top of measuring tape 402, the lagging 4 can provide installation space for solid fixed ring 401, gu fixed ring 401 can link to each other lagging 4 and front end housing 1 are firm, lagging 4 still can provide activity space for measuring tape 402, when gag lever post 5 promotes screw rod 502 through connecting seat 501 and removes, connecting seat 501 can drive measuring tape 402 through connecting rod 403 and remove along lagging 4, it together removes to drive measuring tape 402 and connecting seat 501, a side edge of lagging 4 is located the edge of front end housing 1, thereby make the staff learn the elongation of screw rod 502 through the scale mark that stretches out lagging 4 on the direct observation measuring tape 402, it is convenient to provide for staff's judgement.

The working principle is as follows: before using the cylinder with the internal lubricating function, whether the device has the problem of influencing use or not is checked, when people need to use the device, a fixing part for the device is firstly installed at a working place from an installation hole 702, then a worker needs to connect the fixing part for the high-pressure air pipe with an air inlet hole 301, then a lubricating oil pipeline is connected with a connector 201 to provide lubricating oil for the device, finally the worker connects a device needing to be screwed out of a nut 503 and a screw 502 in a threaded mode or sleeves the device on the outer side of the screw 502 through the cylinder, the nut 503 is screwed on the outer side of the screw 502, and a high-pressure gas system is started to provide high-pressure gas for the device, so that the device can operate and push the device installed on the outer side of the screw 502 to move.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
