Locking member 5 can have numerous embodiments to realize in the present invention, be described in detail below by two embodiments several
Position annexation between the modular construction of implementation method and each part.
Embodiment one：As shown in fig. 6, the locking member 5 includes rotating ring 51, the madial wall of the rotating ring 51 can be with slip
Post 10 is fitted, and the madial wall of rotating ring 51 is the vertical plane fitted with slide post 10 as illustrated in the drawing, and the rotating ring 51 is by many
The annular space array of block rotating ring block 512 sets and constitutes, and is respectively equipped between the lateral wall and hypomere 12 of the rotating ring 51 and matched
The first inclined plane 513 slided, because rotating ring 51 is to be made up of polylith rotating ring block 512, in the presence of the first inclined plane 513,
When piston 4 promotes rotating ring 51, rotating ring 51 to realize that directly reducing diameter embraces by changing the spacing distance between each rotating ring block 512
Tight slide post 10, realizes the radial direction locking to slide post 10.
Further, as shown in FIG., connected by throw-out collar 9 between the rotating ring 51 and piston 4, the locking of the throw-out collar 9 connects
It is connected on piston 4, embedded location structure 103 is respectively equipped between the throw-out collar 9 and piston 4 and between throw-out collar 9 and rotating ring 4,
Being easy to the structure setting of the assembling of device, embedded location structure 103 should not influence the scaling activity of interior ring 53 of stopping；Further, such as
Shown in figure, the first L-type location structure 101 that can mutually catch on is provided between the throw-out collar 9 and rotating ring 51, be easy to part it
Between positioning assembling, free gap 102 is formed between the throw-out collar 9 and rotating ring 51, can be conveniently each by the structure setting
The orderly rigging position one by one of part, during assembling between each part can either mutually defined position easily assemble, again will not be mutual
Limitation causes assembling difficult, because rotating ring 51 is that polylith split is constituted, be it is scattered to assemble one by one, be to compare in assembling
It is troublesome, thus by above-mentioned first L-type location structure 101, it is also just convenient to position placement, it is convenient for assembly, additionally it is possible to be used for
Rotating ring 51 reduces or scale space during enlarged diameter；Further, as shown in fig. 7, the hypomere 12 is provided with outer stop ring 52, institute
The first inclined plane 513 is stated to set on the madial wall of ring 52 of stopping outside, it is described to stop ring 52 by the annular space of ring block 521 of being stopped outside polylith outward
Array sets and constitutes, and the madial wall of the hypomere 12 is provided with the embedded groove 121 for the insertion of ring 521 of stopping outward, when piston 4 promotes dynamic
During ring 51, rotating ring 51 extrudes outer ring 52 of stopping in the presence of the first inclined plane 513, and the enlarged diameter of ring 52 of stopping outward, ring 52 of stopping outward has
It is compact beneficial to the movement structure between each part, holding effect can be lifted.
Embodiment two：As shown in figure 5, the locking member 5 includes interior stop ring 53 and rotating ring 51, interior the interior of ring 53 of stopping
Side wall can fit with slide post 10, and the interior madial wall for stopping ring 53 is the vertical plane fitted with slide post 10, institute as illustrated in the drawing
Stopped in stating and the second inclined plane 514 of the slip that matches is respectively equipped between ring 53 and rotating ring 51, the interior ring 53 of stopping is by polylith
The annular space array of ring block 531 of inside stopping sets and constitutes, interior in the presence of the second inclined plane 514 when piston 4 promotes rotating ring 51
Ring 53 of stopping realizes that directly reducing diameter holds slide post 10 tightly, realizes by changing the spacing distance between ring block 531 of being stopped in each
Radial direction locking to slide post 10.
Further, as shown in FIG., connected by throw-out collar 9 between the rotating ring 51 and piston 4, the locking of the throw-out collar 9 connects
It is connected on piston 4, embedded location structure is respectively equipped between the throw-out collar 9 and piston 4 and between throw-out collar 9 and interior ring 53 of stopping
103, being easy to the structure setting of the assembling of device, embedded location structure 103 should not influence the scaling activity of interior ring 53 of stopping；Enter one
Step, as shown in FIG., the rotating ring 51 is to be set to constitute by the annular space array of polylith rotating ring block 512, the throw-out collar 9 and rotating ring
The the first L-type location structure 101 that can mutually catch on is provided between 51, between being formed with activity between the throw-out collar 9 and rotating ring 51
Gap 102, the orderly rigging position one by one of each part can be facilitated by the structure setting, can either phase between each part during assembling
Mutual defined position is easily assembled, and will not mutually limit again causes assembling difficult, is zero because rotating ring 51 is that polylith split is constituted
Scattered will assemble one by one, be cumbersome in assembling, therefore by above-mentioned first L-type location structure 101, also just conveniently can
Positioning is placed, convenient for assembly；Further as shown in FIG., interior the stopping is provided with what can mutually be caught between ring 53 and epimere 11
Second L-type location structure 104, interior the stopping is formed with for free gap 102 convenient for assembly, the knot between ring 53 and epimere 11
The action effect that structure is set is ibid.
Further, as shown in figure 1, the hypomere 12 is provided with outer ring 52 of stopping, first inclined plane 513 is set stops outside
On the madial wall of ring 52, the outer ring 52 of stopping is set by the annular space array of ring block 521 of being stopped outside polylith and constituted, the hypomere 12
Madial wall is provided with the embedded groove 121 for the insertion of ring 52 of stopping outward, when piston 4 promotes rotating ring 51, in the first inclined plane 513 and the
Rotating ring 51 extrudes interior stop ring 53 and outer ring 52 of stopping in the presence of two inclined planes 514, and ring 53 of inside stopping reduces diameter, and ring 52 of stopping outward expands
Diameter, being provided with for ring 52 of stopping outward is compact beneficial to the movement structure between each part, can lift holding effect.
By taking the structure of the locking member 5 of Fig. 1 as an example, operation principle is illustrated, during work, hydraulic oil is injected by oil inlet and outlet
In hydraulic fluid chamber 42 following in figure, piston 4 is promoted to act upwards, piston 4 promotes rotating ring 51 to push up, ring 53 of being stopped in extruding contracts
Minor diameter is close on slide post 10, the outer enlarged diameter of ring 52 of stopping of extruding, now to hold state tightly, holds stabilization, slide post 10 tightly
When being positioned, and unclamping holding, then to hydraulic oil is injected in hydraulic fluid chamber 42 above in figure, make the downward actuation of piston 4, move
Ring 51 is pulled down, and, not by thrust, ring 53 of inside stopping unclamps to be held tightly, and slide post is slidably for inside stop ring 53 and outer ring 52 of stopping.
Above-mentioned interior ring 53 of stopping, rotating ring 51 and outer ring 52 of stopping are by changing stopped in each ring block 531, each and of rotating ring block 512
Spacing distance between outer ring block 521 of stopping is come the direct diminution and amplification of ring 53 of being stopped in realizing, rotating ring 51 and outer ring 52 of stopping.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from patent category of the invention.
