Described holding paper structure include located at the plate top surface left and right sides pressing plate and make that pressing plate and base plate compress can
The fastener of dismounting.Using fastener and pressing plate, the mode compared to traditional milling tools clip holding paper can preferably be consolidated
Determine sand paper, sand paper is will not fall off in polishing.
Described fastener is bolt, and each pressing plate realizes the fastening with base plate by 2 bolts.Can be fine by bolt
Pressing plate is compressed, 2 bolt presses, one pressing plate be can stabilization clamping platen minimum number.
Pressing plate is equal sized with the anterior-posterior length of base plate, and 4 bolts on 2 block pressur plates are symmetrical and front and rear symmetrically set
Put, the front/rear end left dimensional space that has for compress sand paper of the bolt from base plate or pressing plate.Before between pressing plate and base plate
The space that rear portion is stayed is easy to stretch into sand paper, is easy to compress sand paper.
Described pasting board is soft pvc materials.Pasting board uses flexible PVC material, prevents static contact of damaging in bruting process,
Soft material can also make sand paper be fitted completely with static contact, improve polishing effect.
Beneficial effect：This instrument small volume, may act on narrow space, and 360 degree of rotatable couplings can be added with external
Long handle, rotatable design can comprehensive polishing static contact；Using bolt and pressing plate, compared to the folder of traditional milling tools
Paper mode can preferably fix sand paper, sand paper is will not fall off in polishing；By flexible PVC pasting board, bruting process is prevented
In damage static contact, soft material can also make sand paper be fitted completely with static contact, improve polishing effect.Beaten by this instrument
Mill, the consuming time is short, and polishing effect is good, for the safe and stable operation of load ratio bridging switch provides sound assurance.

Specific embodiment
Technical scheme is described in further detail below in conjunction with Figure of description.
As shown in Figure 1-2, a kind of specific purpose tool for V-type load ratio bridging switch of polishing, including horizontal direction base plate 2,
The pasting board 1 fitted with Sand paper for polishing 7 below base plate 2, above base plate 2 before and after both sides for fixing sand paper 7
Holding paper structure, located at the handle 5 of the top surface of base plate 2, handle 5 can 360 degree be rotatingly connected to the middle part of base plate 2, handle 5 includes and bottom
Plate 2 rotate connection vertical connector 501, located at the top of connector 501 and with the level of base plate 2 to the connection in small angle inclination
Bar 502, connecting rod 502 is connected with dismountable extension bar 6, and connecting rod 502 is coaxial with extension bar 6.
For the ease of stretching into narrow and small switch inner wall space, the horizontal direction angle of connecting rod 502 and base plate 2 is at 5 ~ 35 degree
Between.The angular range is easy to the instrument for being connected to extension bar 6 to stretch into narrow and small switch inner wall space.
For the ease of manufacture, connector 501 is with connecting rod 502 for Integral bending is molded.Integral bending is molded, easily manufactured
Quickly, structural strength is high.
Realization for convenience is detachably connected, and is connected through a screw thread between connecting rod 502 and extension bar 6.Threaded connection
Simple structure, is easy to implement and is detachably connected.
In order to be able to sand paper 7 is firmly fixed, holding paper structure includes being located at the pressing plate 3 of the top surface left and right sides of base plate 2 and makes
Dismountable fastener that pressing plate 3 is compressed with base plate 2.Using fastener and pressing plate 3, pressed from both sides compared to traditional milling tools clip
The mode of paper can be such that sand paper 7 is will not fall off in polishing with stronger fixed sand paper 7.
In order to realize preferably compressing effect, fastener is bolt 4, and each pressing plate 3 is realized and base plate 2 by 2 bolts 4
Fastening.Pressing plate 3 can be compressed well by bolt 4, it is that can stablize clamping platen 3 that 2 bolts 4 compress a pressing plate 3
Minimum number, and it is good to compress effect.
Stretch into and compress for the ease of sand paper 7, pressing plate 3 is equal sized with the anterior-posterior length of base plate 2, on 2 block pressur plates 34
Individual bolt 4 it is symmetrical and it is front and rear be symmetrical arranged, bolt 4 left has for compressing from the front/rear end of base plate 2 or pressing plate 3
The dimensional space of sand paper 7.The space that front and rear part is stayed between pressing plate 3 and base plate 2 is easy to stretch into sand paper 7, is easy to compress sand paper 7.
In order to lift polishing effect, pasting board 1 is soft pvc materials.Pasting board 1 uses flexible PVC material, prevents bruting process
In damage static contact, soft material can also make sand paper 7 be fitted completely with static contact, improve polishing effect.
Before polishing V-type load ratio bridging switch static contact, first sand paper 7 is fitted pasting board 1, the front and back end of sand paper 7
The front and rear part platen position stretched into after selecting between base plate 2 and 2 pressing plates 3 is turned over, pressing plate 3 is depressed, then 4 bolts 4 is tightened fixation,
Then extension bar 6 is connected in oblique connecting rod 502, hand stretches into narrow and small switch inner wall space by the rod handle of extension bar 6, to inwall
On static contact polished, due to handle 5 can 360 degree rotation, and extension bar 6 because connecting rod 502 gradient and and work
The tool oblique connection of body, is easy to stretch into narrow and small switch inner wall space and the static contact to diverse location is polished.
A kind of specific purpose tool for V-type load ratio bridging switch of polishing shown in figure 1 above -2 is specific reality of the invention
