There is a groove on both sides of the inner surface. At least one side of each groove is a toothed rib plate 11. The lower end of the pull rod 2 is connected to the anti-slow positioning mechanism 3. The positioning block 35 of the mechanism 3 is covered by the upper handle of the switch handle 4. 42, protruding or concealing from the hole 311. When the handle cover 42 on the switch handle 4 is pressed down, the positioning block 35 is retracted in the hole 311 of the positioning mechanism 3 through the connecting rod 32, and the pull rod 2 can be freely expanded and contracted. When unclamping the handle cover 42 on the switch handle 4, the sliding block 34 ejects the positioning block 35 under the effect of the spring 33, and is stuck in the teeth of the positioning toothed rib plate 11, so that the pull rod 2 is positioned. As can be seen from FIG. 3 , the teeth of the rib plate 11 injected integrally with the cover plate 1 on the cover plate 1 are concave in shape, and the sides of the rib plate 11 have transverse reinforcing ribs. In this way, the positioning tooth-shaped rib plate 11 and the cover plate 1 are injected into one body, which can reduce the manufacturing cost, simplify the mechanism and prevent the pull rod from being unable to position due to the loosening of the positioning rack. As can be seen from Figure 1, the pull rod 2 is a cylindrical pull rod with positioning holes at both ends. The positioning hole connects the pull rod 2 with the positioning mechanism 3 and the switch handle 4. As can be seen from Fig. 2, Fig. 4, Fig. 5 and Fig. 6, the anti-slow positioning mechanism 3 includes a housing 31 fixed at one end of the pull rod 2, a connecting rod 32 connecting the switch handle 4 and the sliding block 34 at both ends, respectively, Covered on the connecting rod 32, the spring 33 stuck between the connecting pin 36 and the housing 31, the sliding block 34 hinged at one end of the connecting rod 32 and the hole 311 installed in the housing 31 and stuck outside the sliding block 34 Locate block 35. Said housing 31 is of a matching type with a hole 311 on one side and positioning posts on the other two sides, and said hole (311) is square. Described sliding block 34, one end is the cylinder that groove, hole are arranged, and the other end is the cuboid that one side has trapezoidal projection 341. The positioning block 35 has two protrusions 351 on one side that are adapted to the tooth shape on the rib plate 11, and the teeth on the rib plate 11 and the trapezoidal protrusions 351 on the positioning block 35 are arc-shaped. The other side of the positioning block 35 is a groove with a trapezoidal protrusion 352 inside. The positioning column 312 on the housing 31 is stuck in the positioning hole at the end of the pull rod, and the positioning mechanism 3 is fixed on the pull rod 2 . When the handle cover 42 on the switch handle 4 is pressed down, the sliding block 34 is moved downward by the connecting rod 32, and the trapezoidal protrusion 352 of the positioning block 35 falls into the concave part of the sliding block 34, retracting into the positioning mechanism In the hole 311 of 3, the pull rod 2 can freely expand and contract. When the handle cover 42 on the switch handle 4 is loosened, the sliding block 34 moves upward under the action of the spring 33, and the trapezoidal protrusion 341 of the sliding block 34 pushes against the position of the trapezoidal protrusion 352 of the positioning block 35 On, the positioning block 35 is ejected, and the protrusion 351 of the positioning block 35 is stuck in the teeth of the positioning tooth-shaped rib plate 11, so that the pull rod 2 is positioned. It can be seen from FIG. 2 and FIG. 7 that the switch handle 4 includes a handle body 41 fixed at one end of the pull rod by an elastic block 411 , and a handle cover 42 connected with the handle body 41 by an elastic hook 421 . The handle body 41 has at least one elastic block 411 in the holes on both sides, and a groove with a boss on the outside, and a hole 412 on it. The hole 412 is circular, and there are two holes in the middle. A cylindrical object 413 protruding upwards. The handle cover 42 has at least two elastic hooks 421 at its two ends, and there are two cylindrical bodies corresponding to the positions of the cylindrical object 413 on the handle body 41 between the two elastic hooks 421. 423 and a cylindrical object 422 corresponding to the position of the hole 412 on the handle body 41 . The elastic blocks 411 in the holes on both sides of the handle body 41 are respectively locked in the positioning holes at the other end of the pull rod 2 to fix the handle body 41 on the pull rod 2 . The cylindrical body 423 on the handle cover 42 is inserted into the cylindrical object 413 on the handle body 41 to play a role in positioning and limiting the downward movement distance of the handle cover 42 . The elastic hooks 421 on both sides of the handle cover 42 are inserted into the grooves with bosses in the holes on both sides of the handle body 41, and the elastic hooks 421 are stuck by the bosses, so that the handle cover 42 can only move downwards and cannot be disengaged from the handle. Handle body 41 . One end of the connecting rod 32 is inserted into the cylindrical object 422 on the handle cover 42 through the hole 412 on the handle body 41 . When the handle cover 42 is pressed down, the connecting rod 32 is pressed down, and when the handle cover 42 is released, the connecting rod 32 jacks up the handle cover 42 under the action of the spring 33 . Because the utility model adopts the above-mentioned technical scheme, the utility model has the characteristics of simple structure, convenient use, difficult loosening of the positioning mechanism, easy assembly, comfortable handle and low manufacturing cost.
