Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Figure 2 is a top view of a long cylindrical filter extraction device provided according to an embodiment of the present invention. Figure 3 is a three-dimensional exploded view of a long cylindrical filter extraction device provided in an embodiment of the present invention. As Figures 1 - 3 shown, the device includes: a main body holder 1, a lifting screw 2, a lifting handle 3, an inertia sleeve 4, an outer pull rod 5, an inner pull rod 6, a tripod 7, and a claw 8.

[0021] Specifically, the lifting screw 2 is sequentially arranged through the tripod 7, the main body holder 1, and the lifting handle 3. The inertia sleeve 4 is installed on the lifting screw 2, and a locking nut 13 is provided at the top end of the lifting screw 2. The lifting screw 2 plays a lifting role.

[0022] One end of the outer pull rod 5 is movably connected to the end of the main body holder 1, one end of the inner pull rod 6 is movably connected to the tripod 7, and the other end of the outer pull rod 5 is movably connected to the other end of the inner pull rod 6 to form a linkage mechanism. The linkage mechanism plays an adjusting role.

[0023] The tail end of the claw 8 is movably connected to the linkage mechanism, and the front end of the claw 8 extends along the outer side wall of the long cylindrical filter 14 and hooks the bottom of the long cylindrical filter 14.

[0024] Preferably, one end of the outer pull rod 5 is movably connected to the end of the main body holder 1 through a connecting pin 9, one end of the inner pull rod 6 is movably connected to the tripod 7 through a connecting pin 9, and the outer pull rod 5 and the inner pull rod 6 are movably connected to each other through a connecting pin 9. In the embodiments of the present invention, each movable part is connected by a connecting pin, making the rotation flexible and the adjustment simple and convenient.

[0025] Preferably, the tail end of the claw 8 is movably connected to the connection part of the outer pull rod 5 and the inner pull rod 6 through a connecting pin 9.

[0026] Specifically, in the embodiments of the present invention, the main body holder 1, the outer pull rod 5, the inner pull rod 6, the claw 8, and the tripod 7 together form a linkage mechanism. By adjusting the lifting screw 2, the claw diameter and height between multiple claws 8 can be driven to change, so as to grasp filters of different specifications.

[0027] Preferably, a screw hole is provided at the middle position of the lifting handle 3, and the lifting handle 3 is threadedly connected to the lifting lead screw 2.

[0028] In an alternative embodiment provided by the embodiment of the present utility model, the lifting handle 3 and the lifting lead screw 2 adjust the jaw diameter and height between multiple jaws 8 through lead screw transmission, and the adjustment accuracy is more reliable.

[0029] After the jaws 8 grip the long cylindrical filter 14, by sliding the inertia sleeve 4 to apply an upward force to the long cylindrical filter 14 through inertia, the long cylindrical filter 14 can be pulled out, which is convenient and labor-saving.

[0030] Specifically, as Figure 1 and Figure 3 shown, a lifting handle washer 10 is also provided between the lifting handle 3 and the main body holder 1.

[0031] Specifically, an inertia sleeve lower washer 11 is further provided at the bottom end of the inertia sleeve 4, and an inertia sleeve upper washer 12 is also provided between the top end of the inertia sleeve 4 and the locking nut 13.

[0032] In the embodiment of the present utility model, by installing a washer at each of the upper and lower ends of the inertia sleeve 4, when sliding the inertia sleeve 4, the thread of the lifting lead screw 2 can be protected from being damaged.

[0033] Specifically, as Figure 2 and Figure 3 shown, the main body holder 1 includes three ends, and each end is connected to a linkage mechanism composed of an outer pull rod 5 and an inner pull rod 6, and each linkage mechanism is connected to a jaw 8.

[0034] Preferably, the main body holder 1 is plastically welded from a steel material.

[0035] Preferably, the inner side surface of the jaw 8 is an arc-shaped structure, which can better fit the filter and make the process of pulling the filter more stable.

[0036] The working principle of a long cylindrical filter removal device provided by the embodiment of the present utility model is as follows: When it is necessary to replace or inspect the filter, before the first use, the lifting lead screw 2 needs to be sequentially passed through the tripod 7 and the main body holder 1; the outer pull rod 5 and the inner pull rod 6 are connected into a linkage mechanism through a connecting pin 9; the jaw 8 is connected to the inner pull rod 6 through a connecting pin 9; the lifting handle washer 10, the lifting handle 3, the inertia sleeve lower washer 11, the inertia sleeve 4 and the inertia sleeve upper washer 12 are sequentially installed on the lifting lead screw 2; finally, the locking nut 13 is installed at the top end of the lifting lead screw 2.

[0037] Then insert the three pulling claws 8 into the long barrel of the long-barrel filter 14. By rotating the lifting handle 3, drive the lifting lead screw 2 to move upward. The upward movement of the lifting lead screw 2 pulls the tripod 7 upward, and then pulls the linkage mechanism composed of the outer pull rod 5 and the inner pull rod 6 to move, so that the three pulling claws 8 contract and thus clamp to the bottom of the long-barrel filter 14. After it is firmly fixed, then slide the inertia sleeve 4 on the upper part of the lifting lead screw 2, and finally pull out the long-barrel filter 14 from the barrel by inertia.
