[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Directional terms mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "side", etc., are only used to refer to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0026] The utility model provides an embodiment 1 of an auxiliary tooling for a column switch. Figure 4 , Figure 4 The top view of a conventional column mounted switch operating mechanism. Figure 4 It can be seen that when the parameters such as the opening and closing speed of the pole switch need to be adjusted, it is necessary to first disassemble several pins and then disassemble the main shaft 8; after the main shaft 8 is disassembled, the positioning sleeve 12 is disassembled, and finally the opening spring 9 can be disassembled to perform subsequent adjustment and maintenance work. The process is very cumbersome, so the utility model develops an auxiliary tooling for the pole switch.

[0027] See also Figure 1 , Figure 2 The auxiliary tooling includes: an operating handle 1, a first bending portion 2, a second bending portion 3, a first tilting portion 4, a second tilting portion 5, a first connecting member 6, and a second connecting member 7. The length of the operating handle 1 is not limited here, but considering the principle of lever, the longer the length of the operating handle 1, the smaller the required operating force; but on the other hand, considering the operating space and the storage problem of the auxiliary tooling, when the length of the operating handle 1 is too long, it will be difficult to store, and it will be inconvenient to use in an environment with a narrow operating space. Therefore, the utility model preferably sets the length of the operating handle 1 to between 20cm and 80cm.

[0028] In this embodiment, the first bending portion 2 preferably adopts a bending structure composed of two vertical planes (the first plane 21 is perpendicular to the second plane 22), and the first plane 21 of the first bending portion 2 is fixedly connected to the bottom end of the operating handle 1. In this embodiment, it is preferred to set the bottom end of the operating handle 1 and the first bending portion 2 as an integrally formed structure, for example, by welding them together. The second plane 22 of the first bending portion 2 is connected to the top of the first tilting portion 4 through a first connecting member 6. Among them, the first connecting member 6 can be a bolt structure, a slot connection structure, etc., and the connection method of the first connecting member 6 is not limited here, and conventional connection methods are all within the protection scope of this utility model.

[0029] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the second bending portion 3 is a tubular component, which can be a hollow tube or an intern tubular metal material. A through hole is provided at the upper end of the first tilting portion 4, and the first bending portion 31 of the second bending portion 3 passes through the through hole and is connected by the second connecting member 7. The second connecting member 7 is preferably composed of a headed pin, a cotter pin, and a flat washer; or the second connecting member is composed of a flat washer, a hexagonal bolt and a nut. The connection method of the second connecting member 7 is not limited here, and conventional connection methods are all within the protection scope of the present utility model. The bottom end of the first tilting portion 4 is a card slot 41 structure, and the card slot 41 is adapted to the corresponding position of the bracket 11, so that the operating handle 1 can be used to perform the positioning and tilting operation.

[0030] See also Figure 1 and Figure 2 , the second bending part 32 of the second bending portion 3 is connected to the second tilting portion 5. In this embodiment, the second bending part 32 of the second bending portion 3 and the second tilting portion 5 are preferably formed as an integral structure, for example, welded together by welding.

[0031] In this embodiment, the second tilting portion 5 is specifically composed of a support plate 51 and a protruding component 52; the support plate 51 is specifically connected to the second bending portion 32, and the protruding component 52 is vertically welded to the support plate 51. The cross-sectional shape of the protruding component 51 can be circular, rectangular, square, triangular, or other irregular shapes, as long as the protruding component 51 can pass through the hole of the hanging spring plate 10 of the opening spring 8. For example: when the cross-sectional shape of the protruding component 51 is circular, the diameter of the cross-sectional shape is smaller than the diameter of the hole of the hanging spring plate 10 of the pole-mounted switch opening spring 8; when the cross-sectional shape is rectangular or square, its length is smaller than the diameter of the hole of the hanging spring plate 10 of the pole-mounted switch opening spring 8; when the cross-sectional shape is irregular, its longest side is smaller than the diameter of the hole of the hanging spring plate 10 of the pole-mounted switch opening spring 8.

[0032] See also Figure 1 , Figure 2 and Figure 3 In order to consider the convenience of operation and simplify the steps of the disassembly process of the opening spring 8, it is preferred that the second bending portion 3, the first tilting portion 4, and the second tilting portion 5 are each two, and are symmetrically arranged with the operating handle 1 as the center. If the second bending portion 3, the first tilting portion 4, and the second tilting portion 5 are one, it is also possible, but the tilting action needs to be performed twice, which is not convenient and quick enough.

[0033] This embodiment uses a specific example to explain the operation process of the auxiliary tooling in detail. For example: if the opening and closing speed of the pole switch needs to be adjusted, first remove the positioning sleeve 12 of the opening spring 8, then engage the card slot 41 structure of the first tilting part 4 with the corresponding position of the bracket 11, and match the protruding component 52 of the second tilting part 5 with the hole of the hanging spring plate 10 to complete the positioning of the auxiliary tooling; after the positioning is completed, the operator only needs to hold the upper end of the operating handle 1 tightly and apply force downward to complete the disassembly process of the opening spring 8. The whole process is simple and convenient, and can save manpower and material resources, greatly improving work efficiency.

[0034] In order to achieve the above purpose, the utility model also provides a second embodiment of an auxiliary tooling for a column switch, which is improved on the basis of the above embodiment 1, and the improvement is that the bottom end of the operating handle 1 and the first bending part 2 are connected in a manner of block and groove cooperation; the second bending part 32 of the second bending part 3 and the second tilting part 5 are connected in a manner of block and groove cooperation. In order to simplify the preparation process of the auxiliary tooling, the connection method of block and groove cooperation can avoid the occurrence of the situation that it is difficult to control the curvature during the one-piece molding process.

[0035] In order to achieve the above purpose, the utility model also provides a third embodiment of an auxiliary tooling for a column switch, which is improved on the basis of the first embodiment, in that the second tilting portion 5 also includes a rubber gasket; the rubber gasket is fixedly attached to the connection between the support plate 51 and the protruding assembly 52. ​​By adding the rubber gasket, the damage of the auxiliary tooling to the hanging spring plate 10 of the column switch can be reduced, and a buffering and protective effect can be played.

[0036] In order to achieve the above purpose, the utility model also provides a fourth embodiment of an auxiliary tooling for a column switch, which is improved on the basis of the above second embodiment, in that the second tilting portion 5 also includes a rubber gasket; the rubber gasket is fixedly attached to the connection between the support plate 51 and the protruding assembly 52. ​​By adding the rubber gasket, the damage of the auxiliary tooling to the hanging spring plate 10 of the column switch can be reduced, and a buffering and protective effect can be played.
