Shown in Fig. 4, determining clamp block 5 is a shell, and shaft 10 is laterally fixed between the shell two symmetrical side walls, and friction head 2 is logical
It crosses shaft 10 and is installed on and determine in clamp block 5, and can be rotated relative to clamp block 5 is determined, friction head 2 does not need great angle of rotation
Degree, as long as the opposite changing of the relative positions can be generated, when torsional spring 11 is in non-deformed state, the friction teeth of friction head 2 is all exposed.
It is arranged with torsional spring 11 in shaft 10, one end of torsional spring 11 is fixedly connected with friction head 2, the other end and determines clamp block 5
Inner wall is fixedly connected；
Friction head poke rod 3 is located at the handheld terminal of overhead jointing clamp ontology 1 and one end and high-altitude of friction head poke rod 3
Jointing clamp ontology 1 is hinged；
One end of draught line 4 is fixedly connected with friction head poke rod 3, the other end is fixedly connected with friction head 2, so that when pendulum
When dynamic friction head poke rod, friction head poke rod 3 is able to drive 10 twisting around the shaft of friction head 2.
Based on existing overhead jointing clamp, the application method of the utility model is, when dynamic binding clip and determines binding clip and clamps high-altitude
When interfacility link, operator is fiddled with friction head poke rod 3 with hand, and friction head poke rod 3 makes to rub by draught line 4
First 2 10 twist back and forth around the shaft, so that friction head 2 and altitude plant connecting line be enabled to generate the opposite changing of the relative positions, set to wear high-altitude
The contact surface of standby connecting line.
In order to facilitate the operation of personnel's operation, friction head poke rod 3 uses warp architecture, conveniently stirs.
Since above structure is similar to cyclist's brake system, can be transformed using bicycle hand brake, it will be certainly
The binder of driving rim brake replaces with friction head 2, is replaced the fixed friction head of existing overhead jointing clamp for using torsional spring
11 can movable friction head 2, while being mounted on overhead jointing clamp ontology 1 for bicycle hand brake as friction head poke rod 3
Handheld terminal, operator hold overhead jointing clamp ontology 1 handheld terminal when, the pinching cyclist as bicycle brake
Lock achievees the purpose that drive friction head 2.
Simultaneously in order to guarantee that friction head 2 can twist, needs to expand and determine the subsequent gap 15 of clamp block 5, so that friction head 2
Terminals have movable space when friction head 2 twists.
Specific embodiment two
Present embodiment two and the difference of specific embodiment one are, as shown in figure 3, further including 6 He of motor
Eccentric wheel 7；And friction head poke rod 3 is to stir straight-bar 3-1 in this embodiment；
Motor 6 is fixed on overhead jointing clamp ontology 1, and the pto shaft drive of motor 6 is combined with eccentric wheel 7；
Eccentric wheel 7 is located at the side of friction head poke rod 3, and above-mentioned side is that 3 shaft of friction head poke rod is towed line 4
The side of pulling force；
When eccentric wheel 7 turns to a certain field angle, shaft and 7 edge of eccentric wheel of friction head poke rod 3 are close to, partially
Heart wheel 7 can push friction head poke rod 3, and then friction head 2 is driven to swing.
Manually mode stirs friction head poke rod 3, the fuselage of motor 6 to present embodiment for replacement by the way of electronic
It can be directly anchored on overhead jointing clamp ontology 1, can also be fixed by an additional microscope carrier 13, and motor
6 should include the devices such as matched switch and retarder, and when motor 6 rotates, band movable eccentric wheel 7 is rotated, due to friction head
The shaft of poke rod 3 and 7 edge of eccentric wheel are close to and drawing of the shaft of friction head poke rod 3 by 2 side torsional spring 11 of friction head
Power, by the promotion of eccentric wheel 7 and the pulling of torsional spring 11, friction head poke rod 3 is in the state that is struck, thus with dynamic friction
First 2 twisting.
Motor selects GM12-N20VA, carries retarder, mobile power source can be used, directly in voltage rating 2.5V or 5V
It connects and is fixed on overhead jointing clamp ontology 1.
Present embodiment uses electric device, reduces the manual operation of operator, improve the effect of abrasion
Rate.
Specific embodiment three
Present embodiment three and the difference of specific embodiment one or two are, as shown in figure 4, the draught line 4
It insulate between friction head 2.
Since friction head 2 also acts as the wiring effect of original metal connection head, it is therefore desirable in draught line 4 and friction head 2
Between be equipped with insulating layer 14 for insulating, prevent electric current do not need by place pass through.
Specific embodiment four
Present embodiment four and the difference of specific embodiment one or two are that the draught line 4 includes interior lines 12
With pipeline casing 8, interior lines 12 are arranged in the pipeline casing 8；It the interior lines 12 can be relative to the pipeline casing 8 along certainly
Body is axially moved；The pipeline casing 8 is fixed on the overhead jointing clamp ontology 1 by multiple pipeline fixed mechanisms 9；It is described
Interior lines 12 connect friction head 2 and friction head poke rod 3.
Interior lines 12 have been main traction actions, so needing to carry out interior lines 12 as protective layer using pipeline casing 8
Protection, pipeline casing 8 limit the movement routine of interior lines 12 using the metal outer pipe outer waterproofing layer structure for capableing of Qu Rao.Meanwhile
Because interior lines 12 and pipeline casing 8 need relative motion, it is therefore desirable to which external pipeline casing 8 is passed through pipeline fixed mechanism 9
Get up, prevents from driving pipeline casing 8 when pulling interior lines 12.
Since above structure is identical as bicycle brake line, bicycle brake line can be directly used as traction
Line 4.
