The utility model discloses the technical scheme who adopts is, a hydraulic pressure elongator fixing device, including twist grip, the horizontal fixed connection of twist grip is in the upper portion outside of connector, and the connector is the drum type, the tensile sleeve pipe of the lower part rigid coupling hydraulic pressure elongator of connector, and the activity of the tensile sleeve pipe of hydraulic pressure elongator inlays and adorns inside the hydraulic pressure elongator piston, and the hydraulic pressure elongator piston passes through high pressure fuel pipe and links to each other with the hydraulic pressure oil pump, the lower part fixed connection support sleeve pipe of hydraulic pressure elongator piston.
The utility model discloses a characteristics still lie in:
four stainless steel twist grips are even fixed connection in the upper portion outside of connector.
The connector is hollow stainless steel cylinder type to four screw holes have all been seted up to the upper portion and the lower part of connector.
The rotating handle is in threaded connection with a threaded hole in the upper portion of the connector through an external thread on the rotating handle.
The lower part of the connector is sleeved outside the hydraulic stretcher stretching sleeve, and the hydraulic stretcher stretching sleeve is fixedly connected through a fixing bolt.
The hydraulic oil pump is a manual oil pump.
The utility model has the advantages that: the utility model discloses a hydraulic stretcher fixing device installs hydraulic stretcher when having solved on-the-spot maintenance high-tension apparatus dismouting manhole bolt and operates the degree of difficulty greatly, the problem that wastes time and energy, the utility model discloses pass through the connector with the tensile sleeve pipe of hydraulic stretcher and enlarged operating space to make the connector drive the stretcher sleeve pipe can light swivelling joint to on the bolt through turning handle, reduced the operation degree of difficulty of stretcher in the installation, the installation effectiveness has been improved, it is big to have changed the operation degree of difficulty of traditional installation hydraulic stretcher, the consumption time is long, working strength is big, the circumstances such as inefficiency promote hydraulic stretcher's installation high efficiency, from the time of reducing the operation degree of difficulty in-process and having ensured installation hydraulic stretcher shorter, thereby effective control the maintenance time limit for a project, the work efficiency of maintainer unit interval has been improved.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a hydraulic stretcher fixing device, as shown in figure 1, including twist grip 1, the horizontal fixed connection of twist grip 1 is in the upper portion outside of connector 2, and connector 2 is the cylinder type, and connector 2's lower part rigid coupling hydraulic stretcher drawing sleeve 4, hydraulic stretcher drawing sleeve 4 activity inlay dress is inside hydraulic stretcher piston 5, and hydraulic stretcher piston 5 links to each other with hydraulic oil pump 8 through high pressure fuel pipe 7, hydraulic stretcher piston 5's lower part fixed connection support sleeve 6.
As shown in fig. 1, four stainless steel rotary handles 1 are uniformly and fixedly connected to the outer side of the upper part of the connector 2.
As shown in fig. 2, the connector 2 is a hollow stainless steel cylinder type, and four screw holes are opened in both the upper and lower portions of the connector 2.
As shown in fig. 1 and 3, the twist grip 1 is screwed with a screw hole in the upper part of the connector 2 through an external thread on itself.
The lower part of the connector 2 is sleeved outside the hydraulic stretcher stretching sleeve 4, and the hydraulic stretcher stretching sleeve 4 is fixedly connected through a fixing bolt 3.
The hydraulic oil pump 8 is a manual oil pump.
