A control rod 101 is fixedly connected to the top of the bottom plate 1. A clamping assembly 4 is provided on the top of the bottom plate 1. The clamping assembly 4 includes a connecting plate 401. On one side of the connecting plate 401, connecting blocks 402 are symmetrically fixed. A rotating block 403 is rotatably connected to the top of the connecting block 402. A threaded rod 404 is rotatably connected between the connecting blocks 402. The rotating block 403 is fixedly connected to the threaded rod 404. A threaded sleeve 405 is sleeved on the outside of the threaded rod 404. A fixed block 406 is fixedly connected to one side of the threaded sleeve 405. A square block 407 is fixedly connected to the reverse side of the threaded sleeve 405. A fixed rod 408 is fixedly connected between the connecting blocks 402. The square block 407 is slidably connected to the fixed rod 408. A rack 409 is fixedly connected to the bottom of the fixed block 406. Gears 410 are symmetrically engaged on both sides of the rack 409. By rotating the rotating block 403, the rotating block 403 drives the threaded rod 404 to rotate. Then the threaded rod 404 drives the threaded sleeve 405 to move. Cooperating with the square block 407 and the fixed rod 408, the threaded sleeve 405 moves more stably. Then the threaded sleeve 405 drives the fixed block 406 to move. Then the fixed block 406 drives the rack 409 to move. Then the rack 409 drives the two gears 410 to rotate simultaneously.

[0027] A fixed column 411 is fixedly connected to the front of the gear 410. A rotating rod 412 is fixedly connected to one side of the fixed column 411. A square plate 413 is fixedly connected to one side of the rotating rod 412. A clamping plate 414 is rotatably connected to one side of the square plate 413. A measuring rod 415 is fixedly connected to one side of the rotating rod 412. The gear 410 drives the fixed column 411 to rotate. Then the fixed column 411 drives the rotating rod 412 to rotate. Then the rotating rod 412 drives the square plate 413 to rotate. Then the square plate 413 drives the clamping plate 414 to rotate. Since the two rotating rods 412 rotate towards each other, the two clamping plates 414 form a clamping force, thus realizing the clamping of the trench cover, and the operation is more convenient. Secondly, the function of the measuring rod 415 is to assist in measuring and installing the trench cover. The rotating block 403 is T-shaped.

[0028] Inside the receiving housing 3, a protection component 5 is provided. The protection component 5 includes a mounting plate 501 which is fixed inside the receiving housing 3. At the top of the mounting plate 501, a plurality of first springs 502 are symmetrically fixed. The tops of the plurality of first springs 502 are fixedly connected to a buffer plate 503. A sliding rod 504 is slidably connected to the top of the receiving housing 3. The sliding rod 504 passes through the top of the receiving housing 3. The bottom of the sliding rod 504 is fixedly connected to a pressing plate 505. On both sides of the sliding rod 504, panels 506 are symmetrically fixed. The bottom of the panel 506 is fixedly connected to a second spring 507. Through the first spring 502, the trench cover plate can be buffered. Then, in cooperation with the second spring 507, the second spring 507 drives the sliding rod 504 to move. Then the sliding rod 504 drives the pressing plate 505 to move, so that the pressing plate 505 presses the trench cover plate, thereby realizing clamping and buffering of the trench cover plate. The bottom of the second spring 507 is fixedly connected to the receiving housing 3.

[0029] The working principle of the present utility model:

[0030] When the present utility model is in use, first, by rotating the rotating block 403, the rotating block 403 drives the threaded rod 404 to rotate. Then the threaded rod 404 drives the threaded sleeve 405 to move. In cooperation with the square block 407 and the fixed rod 408, the threaded sleeve 405 moves more stably. Then the threaded sleeve 405 drives the fixed block 406 to move. Then the fixed block 406 drives the rack 409 to move. Then the rack 409 drives the two side gears 410 to rotate simultaneously. Then the gears 410 drive the fixed column 411 to rotate. Then the fixed column 411 drives the rotating rod 412 to rotate. Then the rotating rod 412 drives the square plate 413 to rotate. Then the square plate 413 drives the clamping plate 414 to rotate. Since the two side rotating rods 412 rotate towards each other, the two side clamping plates 414 will form a clamp, thereby realizing clamping of the trench cover plate, so that only by turning one switch, the plate can be installed, and the operation is more convenient. Secondly, the measuring rod 415 is used to assist in measuring and installing the trench cover plate.

[0031] Through the first spring 502, the trench cover plate can be buffered. Then, in cooperation with the second spring 507, the second spring 507 drives the sliding rod 504 to move. Then the sliding rod 504 drives the pressing plate 505 to move, so that the pressing plate 505 presses the trench cover plate, thereby realizing clamping and buffering of the trench cover plate.

[0032] The above has described in detail an embodiment of the present utility model, but the described content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. All equivalent changes and improvements made according to the application scope of the present utility model should still fall within the scope covered by the patent of the present utility model.
