Through setting up the second spacing part, after accomplishing the regulation to extension rod service length, can stir the shifting block, the shifting block drives spacing picture peg and inserts the second spacing groove under the guide of third spout to fix the relative position of slider and second spout, avoid leading to the load to increase because of the long-time slider that presses of finger, guarantee extension rod service length is adjusted the stability in use, when the fixed of slider and second spout relative position is relieved to the same reason, reverse shifting the shifting block makes spacing picture peg and second spacing groove break away from can, easy operation is convenient.

Through setting up the through-hole, reduce the sliding handle along the gliding frictional force of extension rod, improve the smoothness of sliding handle in the adjustment process, reduce sliding handle in-process wearing and tearing, extension sliding handle's life, simultaneously through the spacing cooperation of ball and first spout, avoid producing relative deflection at the in-process sliding handle who holds sliding handle and extension rod, further improve sliding handle's operating stability.

Through setting up the shell fragment, under the elastic force effect after shell fragment and the conflict of third spacing groove, the slider is spacing in the second spout, guarantee slider and sliding handle's connection is stable, avoid the slider to slide out from the second spout, simultaneously, after slider or gyro wheel are because of using and produce wearing and tearing, can directly spacing slider's both sides, pull out the slider in the second spout from the second spout, on the contrary, when installing new slider, when the width of extrusion shell fragment to the minimum of gyro wheel and the highest of shell fragment is less than holding the groove, insert the slider in the second spout, remove the extrusion to the shell fragment, under the elastic force effect of shell fragment, the slider slides along the second spout, and make gyro wheel and first constant head tank conflict, accomplish first spacing part's installation, easy operation, it is convenient to use.

Through setting up buffer unit, when the slip handle slides to the tip position department that is close to the extension rod along the extension rod, can contradict earlier with the sliding ring, sliding ring atress extrusion spring, second post and first spout produce the friction simultaneously, increase sliding damping, make the slip handle move when being close to extension rod tip position, can slow down sliding speed automatically, avoid slip handle and extension rod slippage, when setting up like this can also avoid adopting conventional spacing, the slip handle produces great impact with conventional limit structure, result in the lacquer liquid on the brush cylinder to be thrown away, reduce the waste of adjusting in-process lacquer liquid, and the regulation convenience to the pollution guarantee slip handle of non-brushing area.
