[0010] Two ends of a plurality of telescopic rods are respectively fixedly connected to the blocking rods of two slides moving on the same straight line, and locking bolts are provided on the telescopic rods.

[0011] Preferably, the slide plate is U-shaped, and sliders are fixedly connected to the opposite surfaces of the two opposite side walls of the slide plate respectively. A sliding groove is provided on the rod body of the positioning rod at a position corresponding to the slider, and the slider is slidably arranged in the sliding groove.

[0012] Preferably, a positioning plate is fixedly connected to the slide plate, a screw rod is connected to the positioning plate via a thread, and the screw rod passes through the positioning plate and presses against the positioning rod.

[0013] Preferably, the center of the positioning rod has a threaded hole, the center of the baffle is fixedly connected to a mounting plate, the mounting plate is fixedly connected to a threaded column, and the threaded column extends into the threaded hole and is threadedly connected to the threaded hole.

[0014] Preferably, the baffle is mesh-shaped.

[0015] The beneficial effects of adopting the above technical solution are:

[0016] This application can achieve the detachable connection between the baffle and the positioning rod through the cooperation of the set threaded column and the threaded hole, and the slide can move on the positioning rod, which can drive the baffle rod to move, so that the baffle rod can form a circular ring with different diameters and can adapt to cutting holes of different sizes.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 In the first embodiment, a downhole protection assembly includes:

[0024] baffle 10;

[0025] The positioning rod 20 is detachably fixed to the baffle 10, and the positioning rod 20 is radiated from the center to the surrounding areas;

[0026] A plurality of slides 30 are movably fixedly connected to each rod body of the positioning rod 20;

[0027] A plurality of blocking rods 40 are respectively fixedly connected to the plurality of slide plates 30;

[0028] A plurality of telescopic rods 50 have their ends fixedly connected to the blocking rods 40 of the two slides 30 moving on the same straight line. The telescopic rods 50 have locking bolts 51 .

[0029] This embodiment is implemented as follows:

[0030] When the present application is in use, the position of the slide plate 30 on the positioning rod 20 is first adjusted according to the size of the discharge hole, so that the slide plate 30 drives the baffle rod 40 to move, so that the diameter of the ring formed by the several baffle rods 40 matches the diameter of the discharge hole, and at the same time, the center of the ring formed by the several baffle rods 40 coincides with the center of the positioning rod 20, and then the baffle 10 is fixedly connected to the positioning rod 20, and the locking bolt 51 of the telescopic rod 50 is tightened, and then the baffle rod 40 is extended into the discharge hole, and the baffle 10 now seals the discharge hole.

[0031] See also Figure 1 、 2 4. The slide 30 is U-shaped. Slide blocks 31 are fixedly connected to the opposite surfaces of the two opposite side walls of the slide 30. A slide groove 32 is provided on the rod body of the positioning rod 20 at a position corresponding to the slide block 31. The slide block 31 is slidably disposed in the slide groove 32.

[0032] The slide plate 30 of the present application is sleeved on the rod body of the positioning rod 20 , and the slider 31 on the slide plate 30 can slide in the slide groove 32 , so that the slide plate 30 can move on the rod body of the positioning rod 20 , and the movement is more stable.

[0033] See also Figure 1 、 2 The slide plate 30 is fixedly connected to a positioning plate 33, and the positioning plate 33 is connected to a screw rod 34 by a thread. The screw rod 34 passes through the positioning plate 33 and presses against the positioning rod 20;

[0034] The screw rod 34 can move on the positioning plate 33 and lock the positioning plate 33 on the positioning rod 20 , thereby fixing the slide plate 30 .

[0035] See also Figure 3 、 4 The center of the positioning rod 20 has a threaded hole 13, the center of the baffle 10 is fixedly connected to the mounting plate 11, the mounting plate 11 is fixedly connected to a threaded column 12, the threaded column 12 extends into the threaded hole 13 and is threadedly connected to the threaded hole 13;

[0036] By installing the threaded column 12 on the mounting plate 11 of the baffle 10 , it can be connected to the threaded hole 13 on the positioning rod 20 .

[0037] See also Figure 1 , the baffle 10 is mesh-shaped;

[0038] The mesh baffle 10 is lighter and is suitable for workers to observe the feeding hole.

[0039] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
