in the process that the rubber cylinder (3) expands outwards, the mounting block (4013) is driven to move on the limiting slide rod (4011) and the L-shaped connecting plate (403) moves integrally, when the L-shaped connecting plate (403) moves to the outer side of the limiting fixing plate (4041), the first matching inclined surface (4031) at the upper end of the L-shaped connecting plate can be slowly matched with the second matching inclined surface (4043) at the end part of the limiting fixing plate (4041), under the matching of the two inclined surfaces and the elastic action of the connecting spring (4023), the position of the limiting stopper (4032) can be moved upwards so as to be in clamping fit with the limiting baffle groove (4042), under the limiting action of the integral position of the L-shaped connecting plate (403), the outer side position of the whole rubber cylinder (3) can be limited, the position of the rubber cylinder (3) is more stable, the rubber cylinder (3) can not generate position offset in the using process, and a better sealing effect can be kept all the time, more convenient use, when deblocking, center tube (8) activity alternates to be set up in last support column (1), the inside of guide sleeve (7) and lower support column (2), can drive whole annular briquetting (502) to shift up through lifting center tube (8), under the connecting action of bracing piece (501), can shift up the overall position of the guide sleeve (7) of bottom, in the in-process of lifting, rotate whole rotating sleeve (101) simultaneously, make it drive connecting plate (105) of bottom together rotate, thereby make the first spacing ejector pad (1051) of bottom rotate, first spacing ejector pad (1051) is in the rotation process, the top of second guide inclined plane (4051) can contact the cooperation on first guide inclined plane (1052) bottom of its bottom and the spacing ejector pad (405) of second, when first spacing ejector pad (1051) continues to rotate, make first guide inclined plane (1052) and second guide inclined plane (4051) can slowly cooperate, guide between two inclined planes, enable first spacing ejector pad (1051) to rotate and to promote second spacing ejector pad (405) and carry out whole moving down, thereby make coupling spring (4023) shrink, and then make spacing dog (4032) and spacing fender groove (4042) of L shape connecting plate (403) one side break away from the cooperation, under the elastic action of spacing spring (4012), enable installation piece (4013) and reset, thereby make the outside of packing element (3) contract inwards.
2. The hydraulic compression type packer capable of being lifted and unsealed according to claim 1, wherein: fixed mounting has annular turning block (1011) on the upside inner wall of rotation sleeve (101), go up the surface upside of support column (1) and seted up annular rotation groove (102), annular turning block (1011) activity sets up inside annular rotation groove (102), evenly distributed is provided with the first spacing spout of a plurality of (103) on the upside inner wall of last support column (1), evenly distributed is provided with the spacing spout of a plurality of second (104) on the downside inner wall of last support column (1).
3. The hydraulic compression packer capable of being lifted and unsealed according to claim 2, wherein: a guide groove (301) is formed in the rubber barrel (3), and a first conical guide portion (3011) is arranged on the outer side of the upper end of the guide groove (301).
4. The hydraulic compression packer capable of being lifted and unsealed according to claim 2, wherein: a plurality of first limiting sliding blocks (503) are uniformly distributed and mounted on the outer surface of the annular mounting frame (5), and each first limiting sliding block (503) is arranged inside a first limiting sliding groove (103) in a corresponding position in a sliding mode.
5. The hydraulic compression packer capable of being lifted and unset according to claim 2, wherein: the outer surface of the guide sleeve (7) is uniformly provided with a plurality of second limiting sliding blocks (701) in a distributed mode, each second limiting sliding block (701) is arranged inside a second limiting sliding groove (104) in a corresponding position in a sliding mode, and a second conical guide portion (702) is arranged on the outer side of the bottom of the guide sleeve (7).
