Description

Push-pull key installation mechanism Technical Field The utility model belongs to the field of push-pull key structures of medical appliances, and particularly relates to a push-pull key installation mechanism. Background When the bending guide wire is used, the bending guide wire can be matched with a handle, the bending direction of the bending guide wire can be controlled by pushing a push-pull key on the handle, and the push-pull key used by the conventional handle is fixed inside the handle, so that the push-pull key cannot be replaced under the condition of not disassembling a handle shell, and the push-pull key is easy to drop by adopting the replaceable push-pull key. Disclosure of utility model The push-pull key installation mechanism provided by the utility model can effectively solve the problems in the background technology. The utility model provides a push-pull key installation mechanism, which comprises A shell with a strip-shaped hole on the surface, a wide hole with a size larger than the width of the strip-shaped hole on the strip-shaped hole, and The push-pull key with one part capable of being inserted into the bar hole and sliding back and forth along the length direction of the bar hole is also provided with a column body capable of penetrating the wide hole but incapable of being pulled out from the bar hole. As a further optimization of the utility model, the part of the push-pull key inserted into the strip-shaped hole is a strip-shaped sliding block. As a further optimization of the utility model, the utility model also comprises a sliding part which is arranged in the shell and is provided with a jack towards the strip-shaped hole, and the column body is inserted into the jack. As a further refinement of the utility model, the post is an interference fit with the socket. As a further optimization of the utility model, two wide holes are arranged, and two long cylinders are also arranged corresponding to the wide holes, wherein the long cylinders are inserted into the jacks. As a further optimization of the utility model, the shell is made of plastic material, and the size of the column body is slightly larger than that of the wide hole. As a further optimization of the utility model, the upper surface of the push-pull key is provided with anti-skid patterns. As a further optimization of the utility model, the bottom surface of the push-pull key is attached to the shell. As a further optimization of the utility model, the bottom surface of the push-pull key is provided with a tilted edge. As a further optimization of the utility model, the wide hole is arranged at the position corresponding to the column body when the push-pull key stays in the middle of the bar-shaped hole. The push-pull key installation mechanism provided by the utility model can freely replace the push-pull key without disassembling the shell, and the installed push-pull key can smoothly complete the push-pull function and is not easy to fall off. Drawings FIG. 1 is a general assembly view of the present embodiment; FIG. 2 is a schematic illustration of the section of FIG. 1; FIG. 3 is a schematic view of FIG. 1 after the push-pull key is removed; FIG. 4 is a schematic view of the interior of the housing; FIG. 5 is a schematic diagram of a push-pull key; Wherein, casing 1, bar hole 1a, wide hole 1b, slider 2, jack 2a, push-pull key 3, slider 3a, cylinder 3b.
