Detailed description of the invention
Fig. 1～Fig. 7 shows a specific embodiment of the sand paper holding structure of this sander of the application, with tradition sand
Paper holding structure is identical, and this sand paper holding structure also includes pedestal 1 and sand paper folder 2, and wherein pedestal 1 is used for installing sand paper
10, sand paper folder 2 is connected with pedestal 1 by rotating shaft I 3, for by described sand paper 10 removably clamping on described pedestal 1.
Described sand paper folder 2 includes clamping part 201 and the drive division 202 laying respectively at described rotating shaft I 3 radially two opposite sides, this sand paper folder 2
Clamping the first station of described sand paper 10 and described sand paper 10 can be unclamped by means of the rotating regulation of described drive division 202
The second station between change.And be cased with two foot in described rotating shaft I 3 and bear against and be connected to described pedestal 1 and sand
Torsion spring I 7 on folder 2, this torsion spring I 7 has so that the stable reseting elasticity at described first station of described sand paper folder 2.
The key improvements of the present embodiment is: be also equipped with on described pedestal 1 making sand paper folder 2 stable at described second station
Open folder stabilizing mechanism.
The described concrete structure opening folder stabilizing mechanism can refer to shown in Fig. 1～Fig. 5, and it includes: be fixed on described pedestal 1
Support 4, be rotatably connected on the spanner 5 on described support 4 by rotating shaft II 9, one end is connected in described rotating shaft II 9, another
Hold the pull bar 6 that the drive division 202 with described sand paper folder 2 matches, and be connected between described pull bar 6 and described spanner 5
Torsion spring II 8.Described pull bar 6 can be changed by means of the rotation regulation of described spanner 5 between A station and B station.Work as pull bar
6 when being in described A station, and the drive division 202 of described sand paper folder 2 strained by pull bar 6 so that described sand paper folder 2 is in described second
Station, such as Fig. 2.When pull bar 6 is in described B station, pull bar 6 unclamps the drive division 202 of described sand paper folder 2 and makes drive division
202 depart from the spacing of pull bars 6, so that described sand paper folder 2 is in described the under the reseting elasticity effect of described torsion spring I 7
One station, such as Fig. 3.And the most described pull bar 6 is in described A station when being in described B station, and described torsion spring II 8 is equal
It is in the state of being locked.So-called " be locked state ", refers to: no matter pull bar 6 is under A station or B station state, described torsion
Spring II 8 all can not rely solely on the elastic force of self and make pull bar 6 or spanner 5 move.Obviously should " be locked state " also include certainly
So do not stress state.
In the present embodiment, as shown in Figure 6 and Figure 7, it includes spiral torsion spring body 801 to the structure of described torsion spring II 8,
This torsion spring body 801 has a Liang Ge foot, and the two foot all outwards straight-line extension and being formed is straight before arranging in angle
Line segment portion 802 and rear straightway portion 803.Described front straightway portion 802 epitaxial end bending arrange and formed be connected to described in draw
Draw rod attachment part 804 on bar 6, this draw rod attachment part 804 is specially curved hook-shape structure, and its hook is connected on described pull bar 6.
The epitaxial end bending in described rear straightway portion 803 arranges and is formed and be connected to rotating shaft connecting portion 805 in described rotating shaft II 9, this turn
Axle connecting portion 805 is specially helical structure, and it wears and is connected in described rotating shaft II 9.
In the present embodiment, described pull bar 6 is U-shaped structure, it is clear that the pull bar 6 of this U-shaped structure has and is positioned at opposite side
An opening and a blind end, its opening is hinged on described spanner 5, its blind end be enclosed within described sand paper folder 2 driving
Outside portion 202.
In conjunction with shown in Fig. 1～Fig. 7, now the using method of this for the present embodiment sand paper holding structure is described below:
First, user both hands or one hand can be pulled spanner 5 and be at the position shown in Fig. 4 and Fig. 5, now pull bar
6 drive divisions 202 straining the most to the right sand paper folder 2, so that the clamping part 201 of sand paper folder 2 leaves pedestal 1 and at the two
Between form a certain size sand paper clamping gap, sand paper folder 2 is in described second station.And now torsion spring II is in and is locked
Tight state (the most now this torsion spring II is in special " be locked state " that nature does not stresses) is transported without band wrench 5
Dynamic, the sand paper clamping gap i.e. formed between sand paper folder clamping part and pedestal will not disappear voluntarily because of the elastic force effect of torsion spring II
Lose, therefore the hand of user is without pushing down spanner 5 all the time, and spanner 5 can be completely disengaged from, thus liberate the both hands of user.
Then, sand paper 9 can be laid on the sand paper installed surface of pedestal 1 by user with the both hands freed, and along
One end of direction indicated by the arrow of Fig. 5 middle and lower part upwards bending sand paper 9, makes this bending end stretch into described sand paper folder clamping part
In clamping gap between 201 and pedestal 1.Compared to traditional structure can only singlehanded be laid the mode installing sand paper 9, this enforcement
The mode that example employing both hands lay installation sand paper 9 is convenient quickly.
Afterwards, user pulls spanner 5 makes it make flip-flop movement counterclockwise centered by rotating shaft II in Figure 5, so that
Spanner 5 is in the position shown in Fig. 2 and Fig. 3.Now pull bar 6 departs from and sand paper folder clamping part 201 under the drive of spanner 5
Contact, therefore the clamping part 201 of sand paper folder is no longer influenced by the position-limiting action of pull bar 6, so that sand paper folder 2 is at the return of torsion spring I
Rotate counterclockwise in figures 4 and 5 centered by rotating shaft I under elastic force effect, until the clamping part 201 of sand paper folder 2 is resisted against
On pedestal 1, now the bending end of sand paper 9 is clamped tightly between sand paper folder clamping part and pedestal, and above-mentioned clamping gap disappears,
Sand paper folder 2 is in the first station shown in Fig. 2 and Fig. 3.And now torsion spring II be also at the state of being locked without drive pull
Hands 5 moves, therefore the hand of user is without pushing down spanner 5 all the time.
Above-described embodiment only for technology design and the feature of the application are described, its object is to allow people will appreciate that this Shen
Content please is also implemented according to this, can not limit the protection domain of the application with this.All according to the application main technical schemes
Equivalent transformation that spirit is done or modification, all should contain within the protection domain of the application.
