It is equipped with a clamping assembly 7；The first driving chamber is provided with brake drum 2, component 8 is driven in the first driving chamber, when the second spiral shell
The input unit of the second screw 5 and drivening piece acts on after nail 5 is screwed in the first screwed hole and the second screwed hole, when the input of drivening piece
The output section of drivening piece can act on the input unit of clamping assembly 7 and the output section of clamping assembly 7 when portion is extruded by the second screw
By the clamping of positioning tube 6.Realize after second screw 5 are screwed in, to all clampings of positioning tube 6, brought greatly to operation
Facility.The design of each positioning tube 6 simultaneously, realize when each positioning tube 6 is inserted into respective positioning hole, installed part 3
Position fix, it is not necessary to by the first screwed hole and the alignment of the second screwed hole, further the installation side of bringing to installed part 3
Just.
For the simple clamping assembly 7 of design structure and drive component 8, as shown in Fig. 6 and Fig. 7, each clamping group
Part 7 includes central tube 71, and central tube 71 is stood in positioning holes center, and the endoporus of central tube 71 is the second driving chamber, when positioning tube 6
Positioning tube 6 is looped around outside central tube 71 when being inserted into positioning hole；Some card-tight parts, each clamping are provided with central tube 71
Portion includes clamping post 72, and telescopic hole is offered on central tube 71, and clamping post 72 is placed in telescopic hole, and the inwall of positioning tube 6 is recessed
Fall into and form hole clipping, clamping post 72 can be stretched in hole clipping, and the end that clamping post 72 is located in the second driving chamber is provided with and can rotated
Roller 73, clamping post 72 is through there is a garter spring 74 in the second driving chamber, the one end of garter spring 74 and clamping post 72
End in the second driving chamber is fixed, and the other end of garter spring 74 is fixed with the second driving cavity wall；In central tube 71
The heart is provided with an extrusion head 75, and extrusion head 75 is conical structure, and the end greatly of extrusion head 75 is close to installed part 3, the small end of extrusion head 75
The one end of a driven rod 77 is connected to, the roller 73 of all card-tight parts is tangent with the side wall of extrusion head 75, and the other end of driven rod 77 prolongs
Extend in the first driving chamber；Component 8 is driven to include driven rod 81, it is interior and with that the one end of driven rod 81 can stretch to the second screwed hole
Two screws 5 are close to, and the other end of driven rod 81 is stretched in the first driving chamber, and the end that driven rod 81 is located in the first driving chamber is consolidated
Surely there is a band motion block 83, with place's extension, the driven rod 77 of all card-tight parts where motion block 83 to the driven rod 77 of all card-tight parts
Be all secured to band motion block 83, driven rod 81 through there is a back-moving spring 82 in the first driving chamber, the one end of back-moving spring 82 with
First driving cavity wall is fixed, and the other end of back-moving spring 82 with motion block 83 with fixing；Wherein, when the second screw 5 is not threadedly coupled
When entering in the second screwed hole, driven rod 81 is stretched in the second screwed hole in the presence of back-moving spring 82, extrusion head 75 it is small
End contacts with roller 73 and in the presence of garter spring 74 in the retraction of clamping post 72 to central tube 71；When the screw thread of the second screw 5
When connecting in the second screwed hole, driven rod 81 is extruded the second screwed hole back-moving spring 82 and is elongated, the big end of extrusion head 75
Contacted with roller 73, clamping post 72 can be squeezed into in the hole clipping in positioning tube 6 and garter spring 74 is compressed.Installed part is installed
When 3, first, each positioning tube 6 is aligned with respective positioning hole, each positioning tube 6 is inserted into positioning hole after allowing, due to
In the presence of back-moving spring 82 so that the small end of extrusion head 75 keeps contacting with clamping post 72, and the now retraction of clamping post 72 is into
Positioning tube 6 is not interfered with heart cylinder 71 to insert, and is held in position cylinder 6 and is inserted into state in positioning hole；Then, the second screw of turn 5,
So that the second screw 5 once penetrates the first screwed hole and the second screwed hole, when being screwed into the second screwed hole, the second screw 5 is opened
Begin extruding driven rod 81 so that the driven rod 81 stretched to originally in the presence of back-moving spring 82 in second screwed hole is extruded
Second screwed hole, now back-moving spring 82 is stretched, while drives driven rod 77 to the movement of band motion block 83 direction, final extrusion head
75 big end and roller 73 are tangent so that clamping post 72 is pressed into hole clipping, and the second screw is fixed, then clamping post 72 is protected
State in the hole clipping that holds.
In order to avoid causing to hinder roller 73 to reach because the diameter of driven rod 77 is bigger than the end face diameter of the small end of extrusion head 75
The small end of extrusion head 75, while ensure that driven rod 77 has sufficiently large diameter, the small end of each extrusion head 75 is connected by connecting rod
Driven rod 77 is connected to, the diameter of connecting rod is equal to the end face diameter of the small end of extrusion head 75.
In order to avoid ensureing that band motion block 83 causes back-moving spring 82 on operating position because only having a back-moving spring 82
It is easily damaged, each driven rod 77 has both passed through a pulling spring 78, each to pull the one end of spring 78 with being fixed with motion block 83,
Each pulling spring 78 other end is fixed with the first driving cavity wall, and each natural extended length for pulling spring 78 is with answering
The natural extended length of position spring 82 is equal.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
