Sand paper circle is replaced, is greatly improved work efficiency.
A kind of rubber connecting rod of quick-replaceable sand paper circle, including pressing key, sliding pawl set, elastic tape, reset spring, pad
Piece, connecting rod, it is characterized in that: pressing builds and slides pawl set and be connected, and sliding pawl set is connected with reset spring upper end, presses and builds, slides
Pawl set, reseting spring sleeve are inside elastic tape, and sliding pawl sleeve gear is stuck in elastic tape internal guide rail, and gasket is fixed on connecting rod
Together, reset spring lower end is connected with gasket, and gasket is stuck in the fixing groove inside elastic tape.
Preferably, press among key compared with both ends slightly it is thick a bit, inside be it is hollow, outside is equipped with and elastic tape internal guide rail phase
The convex block of linking, bottom are equipped with the equally distributed triangle gear being meshed with sliding pawl set.
Preferably, sliding pawl set inside is hollow, and bottom is inverse equipped with being meshed with pressing key teeth wheel and elastic tape internal guide rail
The inclined right angled triangle gear of hour hands, and triangle gear quantity is to press the half of key bottom triangle gear quantity, it is sliding
Pawl covers inclined right angled triangle gear height slightly above pressing counterclockwise and builds gear height, with elastic tape internal guide rail height phase
Together.
Preferably, clockwise inclined long and short equipped with being meshed with sliding pawl set, pressing key internal projections inside elastic tape
Right angled triangle guide rail and the fixing groove to match with gasket.
Preferably, washer diameter is slightly larger than elastic tape internal diameter, is less than elastic tape outer diameter.
The utility model rubber connecting rod, when pressing key pops up, i.e., pressing is then keyed for rubber by mountable sand paper circle
Circle is internal, and a little so elastic tape slightly expands, sand paper circle will be secured firmly on elastic tape due to slightly thick among pressing key,
It solves the problems, such as that replacement sand paper circle process is excessively complicated, greatly improves working efficiency.

Specific embodiment
The utility model is further described in detail with reference to the accompanying drawing:
As shown, a kind of rubber connecting rod of quick-replaceable sand paper circle, including pressing key (1), sliding pawl set (2), rubber
Enclose (3), reset spring (4), gasket (5), connecting rod (6).Press key (1) it is intermediate compared with both ends slightly it is thick a bit, inside be it is hollow, outside
Side is equipped with the convex block (12) being mutually connected with the interior minister's right angled triangle guide rail (13) of elastic tape (3), and bottom is equipped with and sliding pawl set (2)
The equally distributed triangle gear (9) being meshed, it is hollow for sliding inside pawl set (2), is connected with reset spring (4) upper end,
Bottom be equipped with build gear (9) with pressing and the interior minister's right angled triangle guide rail (13) of elastic tape (3) be meshed it is counterclockwise inclined
Right angled triangle gear (8), and triangle gear (8) quantity is to press the half of key bottom triangle gear (9) quantity, sliding pawl
Gear (9) height is built in the slightly above pressing of inclined right angled triangle gear (8) height to set (2) counterclockwise, internal with elastic tape (3)
Long right angled triangle guide rail (13) height is identical, is equipped with inside elastic tape (3) and sliding pawl set (2), pressing key (1) internal projections
(12) inclined long right angled triangle guide rail (13), short right angled triangle guide rail (11) and and the gasket clockwise being mutually connected
(5) fixing groove (7) to match, the connection pressing of reset spring (4) upper end are built (1), lower end attachment spacers (5), gasket (5) diameter
Slightly larger than elastic tape (3) internal diameter, be less than elastic tape (3) outer diameter, pressing builds (1) and sliding pawl set (2) and is connected, sliding pawl set (2) and
