Wherein, an axial slot 21 is formed in the support rod 2, and a stop piece which can be embedded along the axial direction of the support rod 2 and is limited in the axial slot 21 in the radial direction is formed at the end part of the operating rod 1.
When the rotary guide rib plate drawing tool provided by the embodiment of the utility model is used, the operating rod 1 can be firstly inserted into the positioning screw thread hole 201, then the axial groove 21 of the supporting rod 2 is aligned to the stop piece at the end part of the operating rod 1, then the supporting rod 2 is axially pushed into the pin shaft hole, at the moment, the operating rod 1 and the support 2 are connected together, and the rotary guide rib plate 200 can be driven to be detached by drawing the operating rod 1.
In the drawing tool for the rotary guide rib plate of the embodiment of the utility model, the operating rod 1 is not in direct contact with the positioning screw thread hole 201, so that the operating rod 1 does not directly apply force to the positioning screw thread hole 201, but applies force to the positioning screw thread hole 201 through the intermediate medium supporting rod 2, that is, the supporting rod 2 can be used as a part for protecting the positioning screw thread 201, thereby avoiding the damage of the operating rod 1 to the positioning screw thread hole 201, and effectively ensuring the integrity of the positioning screw thread hole 201 in the dismounting process of the rotary guide rib plate. In addition, the rotary guide rib drawing tool of the embodiment of the utility model has a simple structure, and the end of the operating rod 1 can be embedded by inserting the supporting rod 2 into the pin shaft hole 202, so that the rotary guide rib 200 can be disassembled more simply by applying the rotary guide rib drawing tool, the rapid operation can be realized, and the disassembly efficiency can be improved.
The configuration of the axial slots 21 can be varied according to the utility model.
In a preferred embodiment as shown in fig. 3, the axial slot 21 may include a large inner diameter slot section 211 and a small inner diameter slot section 212 which are sequentially disposed to communicate radially outward from the inside of the axial slot 21, and the stopper is configured to be stopped by a connection of the large inner diameter slot section 211 and the small inner diameter slot section 212, so as to be radially retained in the large inner diameter slot section 211.
Preferably, the stopper and the junction of the large inner diameter groove section 211 and the small inner diameter groove section 212 may be in surface-to-surface contact. Specifically, as shown in fig. 1 and 2, the stopper may be a disk-shaped body 15, and an outer diameter dimension of the disk-shaped body 15 is equal to or less than an inner diameter dimension of the large inner diameter groove section 211 and is greater than an inner diameter dimension of the small inner diameter groove section 212. This way makes the area of contact of disk body 15 and the junction of big internal diameter groove section 211 and little internal diameter groove section 212 bigger, therefore the contact is more stable, is favorable to the stability of action bars 1 with the bracing piece 2 complex.
Also preferably, in the above embodiment, the connection between the stopper and the large inner diameter groove section 211 and the small inner diameter groove section 212 may be point-to-surface contact. For example, the stop may be a sphere that is stopped by the junction of the large inner diameter groove section 211 and the small inner diameter groove section 212.
In the embodiment shown in fig. 4 and 5, the axial slot 21 may have an inner diameter width that decreases sequentially radially outward from the interior of the axial slot 21. As shown in fig. 4, the stopper is an inverted cone-shaped body 16, and the maximum transverse dimension of the inverted cone-shaped body 16 (i.e., the length of the inverted cone-shaped body 16 in the vertical direction shown in fig. 4) is less than or equal to the maximum inner diameter width of the axial slot 21 (i.e., the maximum width in the transverse direction of the cross section of the support rod 2 shown in fig. 5), and is greater than the minimum inner diameter width of the axial slot 21 (i.e., the minimum width in the transverse direction of the cross section of the support rod 2 shown in fig. 5). In such a way, the axial slot 21 and the inverted cone cylindrical body 16 are connected in a mortise and tenon manner, and the quick connection between the operating rod 1 and the supporting rod 2 can also be realized.
According to the present invention, as shown in fig. 2 and 4, the operating lever 1 may include an operating hand lever 11, a connecting rod 12 coaxially connected to the operating hand lever 11, a stopper plate 14 located at an end of the operating hand lever 11 remote from the connecting rod 12, and a slide hammer 13 slidably connected to the operating hand lever 11, the stopper being formed at a free end of the connecting rod 12. The connecting rod 12 is used for connecting the stopper and inserted into the positioning hole thread 201, and after the connecting rod 12 is inserted into the positioning hole thread 201 and connected to the support rod 2, the slide hammer 13 slides upward along the operating lever 11 to strike the stopper plate 14, thereby realizing the loose extraction of the rotation guide rib plate 200.
Preferably, in order to improve the stability of the sliding weight 13 striking the stopper disc 14, the area of the stopper disc 14 may be set to be equal to or larger than the area of the end surface of the sliding weight 13. Further preferably, in order to reduce the production cost and improve the aesthetic appearance of the operation lever 1, the area of the stopper disc 14 may be set equal to the area of the end surface of the slide hammer 13.

The stop boss 17 and the stop disk 14 can limit the sliding of the slide weight 13 therebetween, so as to prevent the slide weight 13 from falling off the operating lever 11 and damaging the rotation guide rib 200.
Preferably, the outer circumference of the connecting rod 12 may be formed with an elastic protection sleeve (not shown in the drawings). The elastic protective sleeve can be made of Teflon (polytetrafluoroethylene), and the material is not easy to be contaminated by impurities, is easier to clean and maintain, and can effectively protect the positioning screw thread hole 201 from being damaged.
More preferably, in order to further prevent the connecting rod 12 from damaging the positioning screw hole 201, the outer diameter of the connecting rod 12 provided with the elastic protection sleeve may be made smaller than the minimum inner diameter of the positioning screw hole 201. I.e. the positioning screw hole 201 is further protected by avoiding the connecting rod 12 from contacting the positioning screw hole 201.
According to the present invention, as shown in the embodiment of fig. 3 and 5, the end surface of the support rod 2 may be further formed with an operation hole 22. The support rod 2 can be inserted into the operation hole 22 by means of an external operation member to push the support rod 2 axially into the pin shaft hole 202.
