The technical solution of the utility model realizes by following measure: a kind of orienting cover takes out instrument, comprises threaded mandrel, sleeve holder, orientation joint and orienting cover; The lower end of sleeve holder is fixedly mounted in the upper end of orientation joint, threaded mandrel comprises threaded rod and push rod, the upper end of push rod and the lower end of threaded rod are fixed together, the tapped through hole of diameter greater than the push rod external diameter arranged in the sleeve holder, be set with orienting cover in orientation joint, threaded rod is installed in the tapped through hole by screw thread and the top that can make the bottom of push rod withstand on orienting cover moves down orienting cover.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
The lower end of above-mentioned push rod can be equipped with cushion block, and threaded rod is installed in the top that also can make cushion block withstand on orienting cover in the tapped through hole by screw thread moves down orienting cover.
The external diameter of above-mentioned cushion block can be less than 1 millimeter to 2 millimeters of orienting cover external diameter.
Above-mentioned threaded rod upper end can be fixed with square spigot, is installed with handle on square spigot.
The dead slot that can have tapped through hole to be connected in the sleeve holder of above-mentioned tapped through hole below, dead slot is up-narrow and down-wide taper.
The inboard outside, upper end with orientation joint, the lower end of above-mentioned sleeve holder can be fixedly installed togather by screw thread.
The utility model reasonable and compact in structure, easy to use, threaded rod is installed in the top that also can make cushion block withstand on orienting cover in the tapped through hole by screw thread moves down orienting cover, not only improved in orientation joint and taken out the efficient of orienting cover, and had the advantages that cost is lower, be convenient to make.
Description of drawings
Accompanying drawing 1 is looked the broken section structural representation for the master of the utility model most preferred embodiment.
Coding in the accompanying drawing is respectively: 1 is the sleeve holder, and 2 is orientation joint, and 3 is orienting cover, and 4 is threaded rod, and 5 is push rod, and 6 is cushion block, and 7 is square spigot, and 8 is handle, and 9 is dead slot.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description is described, as: upper and lower, about etc. the position relation be what to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this orienting cover taking-up instrument comprises threaded mandrel, sleeve holder 1, orientation joint 2 and orienting cover 3; The lower end of sleeve holder 1 is fixedly mounted in the upper end of orientation joint 2, threaded mandrel comprises threaded rod 4 and push rod 5, the lower end of the upper end of push rod 5 and threaded rod 4 is fixed together, the tapped through hole of diameter greater than push rod 5 external diameters arranged in sleeve holder 1, be set with orienting cover 3 in orientation joint 2, threaded rod 4 is installed in the tapped through hole by screw thread and the top that can make the bottom of push rod 5 withstand on orienting cover 3 moves down orienting cover 3.
Can according to actual needs above-mentioned orienting cover taking-up instrument be made further optimization and/or improvements:
As shown in Figure 1, the lower end of push rod 5 is equipped with cushion block 6, and threaded rod 4 is installed in the top that also can make cushion block 6 withstand on orienting cover 3 in the tapped through hole by screw thread moves down orienting cover 3.
