6 are arranged on supporting mechanism 7.Specifically, in the present embodiment, 5 inner surface of sleeve is engaged with the nut head of clamp nut 3, is kept away
The phenomenon that exempting to have skidded in fastener cycle；Sleeve 5 is hollow structure, and opens up cabling channel in the side wall of 5 second end of sleeve
51, the wiring 11 of electrical heating elements 1 is facilitated to be drawn at cabling channel 51.
As shown in Figure 1, supporting mechanism 7 includes support column 72 and support plate 71, support plate 71 is selectively with respect to support column
72 rotations are adjusted, and support plate 71 is parallel with helical centre C1 with respect to the rotation centerline of support column 72, and hydraulic pressure wrench 6 is arranged on
In support plate 71, so that 5 the two of sleeve on hydraulic pressure wrench 6 and hydraulic pressure wrench 6 can follow the opposite support together of support plate 71
Column 72 does stepless rotation and adjusts.Specifically, in the present embodiment, supporting mechanism 7 is also comprising threaded support bar 73, threaded support
The first end of bar 73 is threadedly coupled to be selectively adjusted flexible length of the threaded support bar 73 with respect to support column 72 with support column 72
Degree, the second end of threaded support bar 73 are connected with support plate 71, and threaded support bar 73 is selected during opposite support column 72 is adjusted
Support plate 71 is driven to selecting property to rotate, therefore, support plate 71 is opposite to be supported by the way that the rotation of threaded support bar 73 can be realized
72 collapsing length of column, to match the fastening of the clamp nut 3 of different height, but not limited to this.For example, in the present embodiment
In, first through hole 731 is offered on 73 side wall of threaded support bar, therefore after axis class instrument is interspersed in first through hole 731, at this time
User can be can be achieved with by the rotation process to axis class instrument to flexible tune of the threaded support bar 73 with respect to support column 72
Section, but not limited to this.
Meanwhile supporting mechanism 7 is also comprising being placed on clamp nut 74 in threaded support bar 73, the end face of clamp nut 74 with
The end face of support column 72 abuts, therefore by clamp nut 74, the threaded support bar 73 after adjusting can be fastened, it is ensured that adjustment
71 position reliability of support plate afterwards.Specifically, in the present embodiment, the screw thread of threaded support bar 73 is rectangular thread, to borrow
Rectangular thread is helped to realize higher transmission efficiency, but not limited to this.More specifically, supporting mechanism 7 is also comprising bearing 75, bearing
75 is more excellent without being limited thereto for taper roll bearing, and the outer ring of bearing 75 is set in support plate 71, the inner ring suit of bearing 75
In in the second end of threaded support bar 73；When rotational support plate 71, outer ring and the support plate 71 of bearing 75 rotate synchronously, bearing
75 inner ring is relatively fixed with threaded support bar 73 so that the rotation adjusting of 71 opposite thread supporting rod 73 of support plate is more flexible can
It leans on, but not limited to this.
As shown in Figure 1, to adapt to the fastening of different position clamp nut 3, therefore the clamp device 100 of the utility model also wraps
The sliding assembly 8 being connected between hydraulic pressure wrench 6 and supporting mechanism 7 is included, the glide direction of sliding assembly 8 is double arrows in Fig. 1
Head A is signified so that the clamp device 100 of the utility model is better conformed in small space.Specifically, in the present embodiment,
Sliding assembly 8 includes slide 82 and sliding sleeve in the sliding block 81 on slide 82, and sliding block 81 is connected with hydraulic pressure wrench 6, slide 82 and branch
Support mechanism 7 connects, and is specifically that slide 82 is installed in support plate 71, so that hydraulic pressure wrench 6 and sleeve 5 can opposite support columns 72
Sliding is adjusted, so that sleeve 5 can fasten the clamp nut 3 at different position.For example, in the present embodiment
In, 82 both ends of slide respectively connect the mandril 9 of the selectively glide direction telescopic adjustment along sliding block 81, with right by mandril 9
Voltage-stablizer skirt 4 abuts, then coordinates the support of support column 72, so that the clamp device 100 of the utility model can be quick
And it is reliably positioned at voltage-stablizer so that tightening operation more convenient and quicker, it certainly, in other embodiments, also can be by slide
82 one end is connected with mandril 9, therefore is not limited；Preferably it is that mandril 9 is threadedly coupled to be selectively adjusted with slide 81
Mandril 9 facilitates mandril 9 with respect to the telescopic adjustment of slide 81 with respect to the collapsing length of slide 81；Second is offered on 9 side wall of mandril
Through hole 91, therefore after axis class instrument is interspersed in the second through hole 91, user can be by grasping the rotation of axis class instrument at this time
Make, can be achieved with to mandril 9 with respect to 81 telescopic adjustment of slide, but not limited to this.In order to enable hydraulic pressure wrench 6 more reliably with
Sliding block 81 is fixedly mounted, thus 81 upper surface of sliding block be provided with it is consistent with the appearance profile of hydraulic spanner 6 be embedded slot (not shown),
6 groups of hydraulic spanner is in being embedded in slot, so that the vibration smaller of hydraulic spanner 6 at work, and the cross sectional shape of slide 82 is
Rectangle or other shapes are for example trapezoidal, inverted trapezoidal, double trapezoid etc., but not limited to this.
With reference to attached drawing, the operation principle of the clamp device of the utility model is illustrated：First, by electrical heating elements 1
Connector be inserted in sleeve 5, and the wiring 11 of electrical heating elements 1 is drawn by the cabling channel 51 of sleeve 5；Then, support plate 71 is passed through
Horizontal rotation and threaded support bar 73 and support column 72 screw-driven, sleeve 5 is adjusted and is inserted on clamp nut 3；
Then, by the second through hole 91 of mandril 9 and the first through hole 731 of threaded support bar 73, clamp nut 74 is threaded to downwards with
Support column 72 is in impaction state, and mandril 9 is screwed out and is pushed up to voltage-stablizer skirt 4, end and voltage-stablizer by mandril 9
The rubbing action of skirt 4 provides torque counter-force；Finally, start hydraulic pump conveying hydraulic oil, driven so as to fulfill hydraulic spanner 6
Sleeve 5 is to the fastening function of clamp nut 3.
Above disclosed is only the preferred embodiments of the utility model, it is impossible to the power of the utility model is limited with this
Sharp scope, therefore the equivalent variations made according to the utility model claims belong to the scope that the utility model is covered.
