Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dilator, specifically a novel dilator. BACKGROUND

[0002] The automobile horn separator, also known as a dilator, is an indispensable tool in existing automobile maintenance. As a special tool for disassembling and assembling the lower arm of the automobile shock absorber ball head, it can efficiently separate the shock angle and effectively improve the work efficiency of automobile maintenance, and can be applied to maintenance work such as automobile shock replacement and straight arm replacement.

[0003] However, the current dilator mainly inserts two wedge-shaped expansion pieces into the structural gap, and by twisting the expansion bolt, the two wedge-shaped pieces are expanded to achieve the expansion purpose. In actual application, since the wedge-shaped pieces on the front side of the dilator are in contact, the overall thickness is the sum of the thicknesses of the two wedge-shaped pieces, and it can only be applied to the case where the part gap is greater than the sum of the thicknesses of the two wedge-shaped pieces, and the application range has certain limitations.

[0004] Therefore, we have designed a new type of dilator based on practical work experience. Through scientific and reasonable design, the design of the traditional dilator with wedge-shaped pieces on the front side has been changed to staggered expansion pieces, so that the thickness of the two expansion pieces is the thickness of an expansion head, and the application range of the dilator is improved.

[0008] As a further preferred embodiment of the utility model, the thickness of the driven expansion plate and the driving expansion plate is the same, and the length of the first expansion head and the second expansion head is the sum of the thicknesses of the driven expansion plate and the driving expansion plate.

[0009] As a further preferred scheme of the utility model: the upper side of the driving expansion plate is provided with a bolt hole, the expansion bolt penetrates the bolt hole and contacts the driven expansion plate.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The novel expander changes the structure design of the traditional expander, that is, the front side of the expander is provided with two wedge-shaped plates, and the expander head and the expansion plate are staggered, when the two expansion plates are combined, the plurality of expansion plates can be arranged along a straight line, so that the expansion gap that can be adapted is reduced by half, and the application range of the expander is improved.
