The collet for clamping described central shaft one end is included, a driving device, the spring clip are connected below the collet
The outer sleeve for being provided with interior tapered of head, the sleeve outside are provided with step, compression are provided with below the step of the sleeve
Spring, the compressed spring lower section are provided with supporting sleeve, and the supporting sleeve is fixed on the table, above the step of the sleeve
It is provided with the depression bar assembly that can be moved up and down.
Preferably technical solution is：The depression bar assembly includes the compression bar being arranged above the step of the sleeve, described
Compression bar one end is rotatablely connected with support base, and the support base is fixed on the workbench, and the compression bar other end and one is pneumatically
Device connects.
Preferably technical solution is：Circular ring structure is provided in the middle part of the compression bar, the compression bar is inserted in the sleeve setting.
Preferably technical solution is：It is provided with buffer unit below the compression bar.
Since above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：
The utility model realizes the function that collet holds axis tightly automatically by the cooperation of compressed spring and sleeve, from
And realize and rotated without limitation, by the cooperation of depression bar assembly, product picking and placeing on collet is facilitated, it is highly practical,
It is suitble to promote.

Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below
Content disclosed by specification understands other advantages and effect of the utility model easily.
Please refer to Fig.1 ~ Fig. 3.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only to
Coordinate the revealed content of specification, so that those skilled in the art understands and reads, is not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model
Revealed technology contents obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", " left side ",
The term on " right side ", " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than enforceable to limit the utility model
Range, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence
Scope.
As shown in Fig. 1 ~ Fig. 3, a kind of pressing device without limitation rotation for central shaft part, the central shaft part 1
Including part 2,2 middle part of part is provided with central shaft 3, includes the collet 4 for clamping 3 one end of central shaft, collet 4
Lower section connects a driving device 5, and the sleeve 6 of interior tapered is provided with outside collet 4, and 6 outside of sleeve is provided with step 7, covers
7 lower section of step of cylinder 6 is provided with compressed spring 8, and 8 lower section of compressed spring is provided with supporting sleeve 9, and supporting sleeve 9 is fixed on workbench
On 10,7 top of step of sleeve 6 is provided with 12 component 11 of compression bar that can be moved up and down.
Preferred embodiment is：As shown in Figures 2 and 3,12 component 11 of compression bar includes being arranged on the step 7 of sleeve 6
The compression bar 12 of side, 12 one end of compression bar are rotatablely connected with support base 13, and support base 13 is fixed on workbench 10,12 other end of compression bar
