One side of the slide plate 20 is fixedly connected with a positioning rod 21. One end of the positioning rod 21 penetrates the mounting groove 5 and extends to the mounting groove 5 Inside, the other end of the positioning rod 21 penetrates the mounting block 4 and extends to one side of the mounting block 4, and one end of the positioning rod 21 extending to one side of the mounting block 4 is fixedly connected with a slider 22. The function of the slider 22 makes people convenient Pull the positioning rod 21, between one side of the sliding plate 20 and one side of the inner wall of the movable groove 18 and located on the outer surface of the guide sliding rod 19, a return spring 23 is fixedly connected. The function of the return spring 23 makes it convenient to fix both sides of the plate 2. Each is provided with a positioning groove 24 adapted to the positioning rod 21, a buffer groove 25 is provided on the top of the fixing plate 2, a guide block 26 is fixedly connected to the bottom of the inner wall of the installation groove 5, and the top end of the guide block 26 penetrates the buffer groove 25 and Extending to the inside of the buffer groove 25, the outer surface of the guide block 26 is sleeved with a buffer spring 27. The buffer spring 27 has a good buffer effect. The bottom of the inner wall of the installation groove 5 is slidingly connected with a sliding block 28, and the top of the sliding block 28 A buffer rod 29 is slidably connected by a pin. The end of the buffer rod 29 away from the sliding block 28 is connected to a buffer block 30 through a pin rotation. The bottom of the buffer block 30 is fixedly connected to the bottom of the inner wall of the mounting groove 5 through a spring, and the top of the buffer block 30 In contact with the bottom of the fixed plate 2, the top of the mounting block 4 and both sides of the mounting groove 5 are fixedly connected with a fixed rod 6, and the outer surface of the fixed rod 6 is provided with an annular groove 7, and the outer surface of the fixed rod 6 is located The top of the annular groove 7 is provided with a guide groove 8, the top of the fixed plate 2 is fixedly connected with a filter element body 9, the top of the filter element body 9 is fixedly connected with a connecting plate 31, and the outer surface of the fixed rod 6 is fixedly connected with an elastic sealing gasket 32 , The elastic sealing washer 32 has a good sealing effect, and both sides of the filter core body 9 are fixedly connected with a connecting plate 10, and the top of the connecting plate 10 is provided with a fixing hole 11 that matches the fixing rod 6. The connecting plate 10 There are clamping grooves 12 inside and on both sides of the fixing hole 11, one side of the inner wall of the clamping groove 12 is fixedly connected with a T-shaped clamping head 13 through a clamping spring, and the bottom end of the connecting rod 3 penetrates the fixing hole 11 And extend to the inside of the fixing hole 11. The connecting rod 3 extends to the bottom of the fixing hole 11 and is provided with a fixing groove 14 which is adapted to the fixing rod 6. Both sides of the inner wall of the fixing groove 14 are fixedly connected with the annular groove 7 The two sides of the matching chuck 15 and the end of the connecting rod 3 extending to the inside of the fixing hole 11 are provided with grooves 16 that are compatible with the T-shaped chuck 13, and the top of the connecting plate 10 is located on the connecting socket. The outer surface of the rod 3 is fixedly connected with a T-shaped indenter 17 adapted to the T-shaped clamp 13 through a connecting spring, and the bottom of the T-shaped indenter 17 penetrates the fixing hole 11 and extends to the inside of the fixing hole 11.
