Provided in the invention is a flexible anti-collision sheath of a telegraph pole, which relates to an anti-collision sheath of a telegraph pole. A plurality of screw rods A (4) are arranged on the outer edge surfaces of an upper hoop (3) and a lower hoop (19); inward horizontal plates (8) are arranged at the upper end and the lower end of an outer long vertical plate (13) respectively, the upperend and the lower end of an inner long vertical plate (12) are fixedly connected to the inner ends of two horizontal plates of the outer long vertical plate, and at least one spring (16) is arranged between the middle of the outer long vertical plate and the middle of the inner long vertical plate. A short vertical plate (9) is arranged above the inner end of each horizontal plate; a downward short vertical plate is arranged at the lower part of the inner end of each horizontal plate to form a set of flexible anti-collision mechanisms, a plurality of upward short vertical plate unthreaded holes (24) of the flexible anti-collision mechanisms sleeve the screw rods A of the upper hoop and then are locked by nuts (7) to form a flexible anti-collision sheath at the outer lower part of a telegraph pole (1), and an outer cylinder (17) wraps the flexible anti-collision sheath. The springs are used for supporting the outer long vertical plate and the inner long vertical plate, and flexible collision avoidance of the telegraph pole is achieved through the springs and the outer long vertical plate .

The invention discloses a starting mechanism of a mechanical time-telling watch. According to the starting mechanism, a through groove is formed on a spacer ring, and a pull core support is fixed in the through groove of the spacer ring; a connecting sleeve is respectively connected and fixed with one end of a pull core and a square end of a shifting hander as a whole, and the other end of the pull core is a free end; the pull core which is sheathed with a waterproof sealing pipe and a pressure spring penetrates through a connecting block and the pull core support; the pressure spring is arranged in a range of the length of the support; the connecting block is fixedly arranged at a gap formed on the pull core; the pull core penetrates through the connecting block, and the connecting block is fixedly connected with a shafting block; the shafting block in contact with or separated from a movement time-telling starting plate; and upper and lower ends of the exterior of the spacer ring are provided with waterproof rubber rings. The starting mechanism of the invention is advantageous in that: because waterproof rubber rings for sealing are arranged between the spacer ring and a watchcase, and a waterproof sealing pipe is arranged between the spacer ring and the inner pull core, the contact between the exterior and the interior is obstructed from an outermost end, and sealing is carried out from the interior, thereby enabling favorable dustproof and waterproof effects to be achieved. According to the starting mechanism, a sealing box is omitted, which enables a watch with a standard size to be small and thin.

The invention belongs to the technical field of steel wire rope production, in particular to a straightening device for steel wire rope production. The following proposals are proposed, including a base, a No. 1 straightening cylinder, a No. 2 straightening cylinder and a No. 3 straightening cylinder. The inner walls of the No. 1 straight barrel and the No. 3 straight barrel are fixedly connected with mounting plates at equal distances. In the present invention, by setting a limit adjustment spring, a mounting plate, an arc-shaped guide plate, a collision plate and a hydraulic cylinder, before the wire rope is straightened, the wire rope passes through the No. 1 straightening barrel, the No. 2 straightening barrel and the No. 3 straightening barrel In the middle, the limit adjustment spring is squeezed, so that the balls on the two limit arc plates just fit the outer wall of the wire rope to realize the limit of the wire rope, and then adjust the hydraulic cylinder to drive the collision plate to limit the arc guide plate. Thereby, the fixing of the limit arc plate is realized, and the straightening effect is reduced due to shaking of the limit arc plate during the straightening process of the steel wire rope.
