It is provided with the downside of support plate, the terminal pad and accommodating box is installed, escape pipe, the accommodating box is installed on the left of the accommodating box
Downside is provided with the downside of connecting rod, the connecting rod and is provided with handle.
As optimal technical scheme of the present utility model, the screw rod, which is connected with casing threads and riveted with support plate, to be connected
Connect.
As optimal technical scheme of the present utility model, the connecting tube be fixedly connected with the first air bag and with the second air bag
Threaded connection.
As optimal technical scheme of the present utility model, the terminal pad is fixedly connected with the second air bag and accommodating box respectively
And connect.
As optimal technical scheme of the present utility model, the connecting rod is fixedly connected with accommodating box.
Compared with prior art, the beneficial effects of the utility model are：
The utility model carries out the sealing that coincide using the first air bag and the second air bag to well head, solves traditional well lid close
Envelope not tight problem, it is to avoid gas leakage, by setting blow vent, preferably the size to the first air bag and the second air bag is entered
Row control, it is convenient that gas flow in first air bag and the second air bag is controlled, so as to conveniently make the first air bag and the second gas
Capsule is brought into close contact to the borehole wall, improves the sealing of device, and by setting through hole, preferably gas is filtered, kept away
Exempt to suction out impurity, by setting connecting tube, preferably the length to the first air bag and the second air bag is controlled, so that convenient
The well head of different-thickness is sealed, the sealing effectiveness of device is strengthened, and simple in construction, reasonable in design, easy to operate, peace
It is complete reliable.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：
A kind of gas pumping hole packer, including connecting tube 3, the first air bag 2 and the second air bag 4, the upper end of connecting tube 3 connect
It is connected to surface and sets threaded the first air bag of cylindricality 2, the uper side surface of the first air bag 2 is uniformly provided with through hole 1, the connecting tube
