325.Second sliding eye 322 and the second driving piece matching hole 323 is elongate holes.Second body of rod 321
Shape is required to meet the distance between second main shaft 122 and the second lever piece 34, specifically, second bar
The shape of body 321 is used to meet between the second protruding axis 12211 and the second lever piece 34 on the second driving piece 1221
Required distance.Second protruding axis 12211 is embedded into the second driving piece matching hole 323.Described second
Blocking lever 32 is slidably arranged on side plate 2, specifically, installation part 4 fixed on side plate 2 is embedded into second sliding eye
It is slided in 322 and in the second sliding eye 322, realizes the relationship that is slidably installed between second blocking lever 32 and side plate 2.
End 325 is replied for cooperating with second lever piece 34, specifically, when second in second pressure side 324 and second
When switch 12 carries out feed motion, driving of second blocking lever 32 by the second driving piece 1221 on the second main shaft 122
And when moving, second pressure side 324 pushes second lever piece 34 to rotate, and pushes institute by the second lever piece 34
The first locking level 113 rotation stated.And when the second switch 12 carries out separating brake movement, second blocking lever 32 by
The driving of the second driving piece 1221 on second main shaft 122 and when moving backward, the second reply end 325 pushes described
Second lever piece 34 rotates backward, and the first locking level 113 is replied because of selfer power.Due to second blocking lever
32 have longer length, and in order to guarantee second blocking lever 32, the processing is simple and stability, second interlocking
The form of splicing can be used to complete in bar 32.For example, second blocking lever 32 includes two sections, when completion, two sections are spliced
Composition second blocking lever 32.
Such as Fig. 6, first lever piece 33 is a sheet, is usually made of metal plate, first lever piece 33
Including the first rotation hole 331, the first limit hole 332, first pushed away end 333 and first reply abutting end 334, described first turn
Dynamic hole 331 is rotatably arranged on side plate 2 for first lever piece 33 for circular hole, and first limit hole 332 is
Kidney slot cooperates with the limit shaft being fixed on side plate 2, so that the rotational angle of first lever piece 33 suffers restraints.The
One by end 333 is pushed away for cooperating with first pressure side 314, i.e., is contacted by first pressure side 314 and pushes institute
First stated is pushed away end 333.Described first, which replys abutting end 334 and be used to reply end 315 with described first, to be cooperated, described
The first blocking lever 31 reverse movement when, described first reply end 315 pushes described first to reply abutting end 334, thus
First lever piece 33 is driven to rotate backward.
Such as Fig. 7, second lever piece 34 is a sheet, is usually made of metal plate, second lever piece 33
Including the second rotation hole 341, the second limit hole 342, second pushed away end 343 and second reply abutting end 344, described second turn
Dynamic hole 341 is rotatably arranged on side plate 2 for second lever piece 34 for circular hole, and second limit hole 342 is
Kidney slot cooperates with the limit shaft being fixed on side plate 2, so that the rotational angle of second lever piece 34 suffers restraints.The
Two by end 343 is pushed away for cooperating with second pressure side 324, i.e., are contacted by second pressure side 324 and push institute
Second stated is pushed away end 343.Described second, which replys abutting end 344 and be used to reply end 325 with described second, to be cooperated, described
The second blocking lever 32 reverse movement when, described second reply end 325 pushes described second to reply abutting end 344, thus
Second lever piece 34 is driven to rotate backward.
Such as Fig. 8, mounting structure schematic diagram between the first blocking lever 31 and side plate 2, due to first blocking lever
31 need the relationship that is slidably installed with the formation of side plate 2.Specifically, installation part 4 is filled in the corresponding mounting hole of side plate 2, it is described
Installation part 4 be a hollow part, the installation part 4 be equipped with convex edge 41, the convex edge 41 is located at the installation
The middle part of part 4, the two sides of convex edge 41 are respectively relative to the side plate 2 and the first blocking lever 31, and installation part 4 passes through the first interlocking
The first sliding eye 312 on bar 31, and tightened after the installation part 4 with washer 51, the cooperation of nut 52 by screw 5.
