Oil cap 332 is covered after in instrument accommodating chamber 111, operation is lubricated to being cleaned part afterwards.After the completion of operation to be lubricated, maintenance
Personnel can be outwarded winding and lubricate the fastening bolt of the lower end of oil can 33, and the sponge 333 with impurity is taken out from lower end, convenient after cleaning
Next time carries out cleaning lubrication operation to being cleaned part.The lubrication low cost of oil can 33, and easily assembling.
It should be noted that lubricating structure not limited to this, in the other embodiment not shown in figure, lubricating structure can
Think the mechanisms such as rifle of buying oil, fat cup lubrication, fat rifle lubrication.Certainly, as long as it will be apparent to one skilled in the art that will can moisten
Sliding mechanism is placed in instrument accommodating chamber.
As shown in figure 3, in the cleaning plant of the present embodiment, fastener 40 includes holding section 41, holding section 41 has stretches
Enter instrument accommodating chamber 111 and lock the confined state of cleaning tool and leave instrument accommodating chamber 111 and unlock tearing open for cleaning tool
Unload state.Specifically, when maintenance personal is cleared up being cleaned part, after cleaning tool inserter accommodating chamber 111, will
Fastener 40 screws in through hole 112, and holding section 41 and the cleaning tool of fastener 40 carry out lock fit;When maintenance personal need not
When clearing up being cleaned part, fastener 40 is screwed out from through hole 112 so that cleaning tool can be from instrument accommodating chamber
Taken apart in 111.Preferably, holding section 41 has guiding surface.Set guiding surface cause fastener 40 be easier with it is clear
The carrying out of science and engineering tool coordinates.Guiding surface simple structure, is easily worked.
As shown in figure 3, in the cleaning plant of the present embodiment, fastener 40 also includes fixed part 42 and positioned at fixed part 42
With the elastic component 43 between holding section 41, fixed part 42 and the screw thread of through hole 112 coordinate.Preferably, fixed part 42 is with bolt.
Specifically, because different cleaning tools have mismachining tolerance, its assembly precision with the matching part of instrument accommodating chamber 111 is caused not
Together, it is possible that cleaning tool coordinates not closely in being fitted into instrument accommodating chamber 111 with instrument accommodating chamber 111, cleaning is caused to fill
Put and deviate from from instrument accommodating chamber 111, so as to influence the cleaning effect of cleaning plant.When the fixed part 42 and through hole of fastener 40
After 112 threaded connections, can be completely locked at cleaning tool in instrument accommodating chamber 111 by elastic component 43 so that cleaning tool is not
It is easy to deviate from from instrument accommodating chamber 111, so that cleaning tool is more stablized and tight with the connection of cleaning main body 10.
As shown in figure 3, in the cleaning plant of the present embodiment, elastic component 43 is spring.Spring is standard component, uses spring
Production cost can be reduced.
As shown in Fig. 2 in the cleaning plant of the present embodiment, operating portion 20 is the second end for being arranged on cleaning main body 10
Handle.When maintenance personal is cleared up being cleaned part, first alignment is cleaned the screw mandrel of part (gate), and rotating handles drives clear
Reason device.Maintenance personal can according to different demands, drive equipped with difference in functionality cleaning tool, by rotating handles so that
Cleaning main body 10 can carry out scale removal and cleaning work the screw mandrel on part from outside to inside to gate is cleaned.Said structure is processed
Easily, convenient operation, can improve Consumer's Experience.
As can be seen from the above description, the utility model the above embodiments realize following technique effect:
When maintenance personal needs to clear up being cleaned part, the external screw thread for clearing up main body coordinates company with part is cleaned
Connect.Maintenance personal causes that cleaning main body is moved relative to part is cleaned by operating the operating portion of cleaning main body, while band
Cleaning tool in power driven tools connector is moved together, so as to will be cleaned part clean out.So, made using the cleaning plant
Obtain cleaning work of the maintenance personal to being cleaned part more quick, while so that the maintaining for being cleaned part more facilitates.
