Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a bolt, as shown in fig. 2, 3 and 5, which comprises a head part 1 and a rod part 2, wherein the head part 1 is fixedly connected with the rod part 2. First fixed orifices 11 have been seted up to the one end that pole portion 2 was kept away from to head 1, and open-ended one end is kept away from to first fixed orifices 11 is seted up with the second fixed slot 12 of first fixed orifices 11 coaxial line, and second fixed slot 12 is seted up threadedly, and pole portion 2 is seted up the card hole 21 that communicates second fixed slot 12. A threaded rod 3 is connected with the second fixing groove 12 in an internal thread mode, a hexagonal groove 31 is formed in one end, facing the head 1, of the threaded rod 3, and a round rod 32 is fixedly connected to one end, far away from the head 1, of the threaded rod 3. One end of the round rod 32 far away from the threaded rod 3 is rotatably connected with an operating plate 4, and the operating plate 4 penetrates through the clamping hole 21 and extends out of the rod part 2. The sum of the length of the operation plate 4 in the axial direction of the lever portion 2 and the length of the head portion 1 in the axial direction of the lever portion 2 is smaller than the length of the first fixing hole 11 in the axial direction of the lever portion 2.

As shown in fig. 2, 3 and 5, a slot 41 is formed at one end of the operating plate 4 facing the threaded rod 3, a ring groove 42 is formed at one side of the inner surface of the slot 41 and away from the opening, two sliding blocks 33 embedded in the ring groove 42 are fixedly connected to the outer surface of the threaded rod 3, and the two inserting blocks are distributed at equal intervals along the circumferential array of the outer surface of the round rod 32. The inner surface of the slot 41 is provided with two sliding grooves 43 for the two sliding blocks 33 to slide, and the two sliding grooves 43 are both communicated with the ring groove 42 and are distributed along the circumference of the inner surface of the slot 41 at equal intervals. The two sliding blocks 33 are respectively aligned with the two sliding grooves 43 and are embedded into the annular groove 42, so that the threaded rod 3 is connected with the operating plate 4.

As shown in fig. 4 and 5, the operation plate 4 is provided with two stoppers 5 that seal the two slide grooves 43, respectively. The stopper 5 includes an operation hole 51 opened in the operation panel 4 and communicating with the slide groove 43, and an operation lever 52 slidably disposed in the operation hole 51. A limit groove 53 is formed in the side edge of the operation hole 51, and a limit block 54 slidably arranged in the limit groove 53 is fixedly connected to the operation rod 52. The operating rod 52 is driven to move along the axial direction of the stopper groove 53, so that the operating rod 52 is inserted into the slide groove 43, and the slider 33 is prevented from being separated from the operating plate 4 by the slide groove 43.

As shown in fig. 2, 4 and 5, the operating rod 52 is fixedly connected with an operating block 55 at one end far away from the sliding slot 43, and a skid-proof strip 56 is fixedly connected at one end of the operating block 55 far away from the operating rod 52.
