Inclined surface in one, roller configuration is in another one, to roll under the effect of matching piece 23.In this way, when matching piece 23 is opposite
In 21 motion process of bracket, idler wheel moves in the first roll channel 271, and idler wheel is at one of the inclined surface being located above
It is moved downward in a second direction under the action of component relative to bracket 21, a component of the idler wheel in underlying inclined surface
It is moved upwards in a second direction under effect relative to bracket 21, so in the present embodiment, driving rolling may be implemented in effort formation
Wheel drives the reciprocating direction movement of pressure regulation part 22 in a second direction, i.e., answering for pressure regulation part 22 can be realized by effort formation itself
Position, and non-required other setting return unit is to realize the reset of pressure regulation part 22.
Alternatively, the first tilting section 261 and the second tilting section 262 are each configured to two sub- inclined surface on matching piece 23, rolling
Wheel is configured on pressing means 221 or pressure release part 222, and two sub- inclined surface connect the V-shape to be formed with upward slope section and lower slope section,
The control to pressing means 221 or pressure release part 222 so can be achieved by the movement of twocouese (reciprocating direction on first direction)
System, to be rolled under the effect of matching piece 23.
In a further mode of operation, effort formation is used to control both in pressing means 221 and pressure release part 222, at this
When situation, the first tilting section 261 and the second tilting section 262 include that there are two sons of upward slope section and lower slope section to tilt for connection formation
Face, idler wheel include press roll 251 and pressure release wheel 252, and press roll is configured on pressing means 221, and pressure release wheel 252 is configured at pressure release part
On 222, so matching piece 23 relative to bracket 21 move when, the upward slope section of the first tilting section 261 and the second tilting section 262 and
Lower slope section one of them and press roll 251 cooperate to drive pressing means 221 to move in a second direction relative to bracket 21, with
Pressurizing valve is controlled, the upward slope section and lower slope section wherein another one and pressure release of the first tilting section 261 and the second tilting section 262
Wheel 252 cooperates to drive pressure release part 222 to move in a second direction relative to bracket 21, to control relief valve.
Or first tilting section 261 and the second tilting section 262 include two independent sub- inclined surface, one of son inclination
Face forms upward slope section, and another sub- inclined surface forms lower slope section, be not limited thereto.
Refering to Fig. 5, specifically, matching piece 23 includes the first auxiliary section 231 and the second auxiliary section 232, the first auxiliary section 231
Including the first tilting section 261, the second auxiliary section 232 includes the second tilting section 262.When the first auxiliary section 231 and the second auxiliary section
After 232 docking, the first tilting section 261 and the second tilting section 262 are configured to above-mentioned effort formation, and space shape between the two
At above-mentioned first roll channel 271.
In further embodiments, it after the first auxiliary section 231 is docked with the second auxiliary section 232, is also formed and the first rolling
The second roll channel 272 that dynamic channel 271 is connected to, during matching piece 23 is moved relative to bracket 21 along first direction,
Idler wheel can enter in the second roll channel 272 from the first roll channel 271, or enter first from the second roll channel 272
In roll channel 271, and when idler wheel moves in the second roll channel 272, matching piece 23 will not apply any in a second direction
Active force is in pressure regulation part 22, therefore when idler wheel moves in the second roll channel 272, and pressure regulation part 22 is relative to bracket 21 along
Two directions remain stationary.
In a kind of mode, rolling member 25 and effort formation are for controlling one in pressing means 221 or pressure release part 222
System, the first tilting section 261 and the second tilting section 262 are configured on the pressing means 221 controlled or pressure release part 222 and matching piece 23
Inclined surface or the first tilting section 261 and the second tilting section 262 in one include that connection is formed with upward slope section and lower slope section
Two sub- inclined surface, after the first auxiliary section 231 is docked with the second auxiliary section 232 formed second roll channel 272, should
One the second roll channel 272 is connected to wherein one end of above-mentioned first roll channel 271, press roll 251 or pressure release wheel 252
From the first roll channel 271 enter the second roll channel 272 in after, may be implemented pressing means 221 or pressure release part 222 relative to
Bracket 21 is motionless in a second direction.
