The sealing joints of the oil supply, oil return and ventilation pipes of the gas turbine bearing cavity in the aircraft turboshaft engine need to be installed and connected with copper washers during use. In actual use, the copper washers need to be replaced after a period of use.

[0003] Since the copper washer is installed inside the propeller hub, in the existing replacement process, a tool with a hook at the end is generally used to extend into the propeller hub, and then the washer is hooked out through the hook. However, in actual use and operation, since the end of the hook is relatively sharp, it is easy to scratch the inside of the propeller hub during the removal process, and when hooking the washer, the head of the hook needs to be aligned with the position of the washer before the washer can be hooked out, and the removal process of the washer is relatively inconvenient. Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0034] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the utility model, which includes a mounting seat 10, a clamping member 20, an extrusion rod 30 and a movable seat 40.

[0035] The clamping member 20 is arranged on the mounting seat 10. The clamping member 20 has a through hole 201 penetrating the inside of the clamping member 20. The lower end surface of the clamping member 20 is integrally provided with a groove 202 connected to the through hole 201. The groove 202 is provided in multiples. The multiple grooves 202 separate the lower end of the clamping member 20 to form multiple elastic clamping parts 21. In this embodiment, the outer wall of the mounting seat 10 is provided with a first anti-slip surface 11. The first anti-slip surface 11 is used to provide sufficient friction when the user holds the mounting seat 10, thereby preventing the user from slipping during use. The outer walls of the lower ends of the multiple elastic clamping parts 21 are respectively provided with mutually matching positioning grooves 203. The positioning grooves 203 are used to fix the gasket in the positioning grooves 203 to prevent the gasket from sliding up and down on the clamping member 20. The mounting seat 10 has a sliding groove 101 extending up and down. The side wall of the sliding groove 101 is provided with a limit groove 102 extending up and down. The grooves 202 are four in number and arranged at equal angles, and correspondingly, the elastic clamping parts 21 are four in number and arranged at equal angles. Similarly, the number of the grooves 202 can also be other numbers set according to actual conditions, and is not limited thereto. The depth of the grooves 202 is half the length of the clamping member 20. The depth of the grooves 202 is deep enough to reduce the force required to open the elastic clamping parts 21, further facilitating the removal process of the gasket.

[0036] The upper end of the extrusion rod 30 can be slidably arranged on the mounting seat 10, and the lower end of the extrusion rod 30 passes through the through hole 201 and extends downward from the clamping member 20. The lower end of the extrusion rod 30 is provided with an extrusion portion 31 that cooperates with the elastic clamping portion 21. The extrusion portion 31 expands the elastic clamping portion 21 outward as the extrusion rod 30 slides upward, and fixes the gasket in the hub to the elastic clamping portion 21 through the elastic clamping portion 21 that expands outward. In this embodiment, the extrusion portion 31 is a frustum, and the outer peripheral side wall of the extrusion portion 31 is provided with a guide surface 32 that cooperates with the elastic clamping portion 21. The guide surface 32 not only facilitates the process of expanding the elastic clamping portion 21 outward with the extrusion portion 31, but also facilitates the resetting process of the elastic clamping portion 21. The upper end of the extrusion rod 30 is provided with a connecting member 33, which is arranged in the sliding groove 101 and is arranged to slide back and forth along the extension direction of the sliding groove 101. The connecting member 33 is provided with a limiting rod 34, which extends inwardly into the limiting groove 102, so that the extrusion rod 30 is limited by the cooperation between the limiting groove 102 and the limiting rod 34 to prevent the extrusion rod 30 from rotating in the sliding groove 101; the connecting member 33 is provided with a connecting hole 301.

[0037] The movable seat 40 can be movably arranged on the mounting seat 10, and the movable seat 50 is connected to the upper end of the extrusion rod 30 and drives the extrusion rod 30 to move up and down, so that the washer is fixed on the elastic clamping part 21 through the movable seat 40; the outer wall of the movable seat 40 is provided with a second anti-slip surface 41, and the second anti-slip surface 41 is used to prevent the movable seat 40 from sliding with the user when the user is in use. In this embodiment, a connecting rod 42 is formed at the lower end of the movable seat 40, and the connecting rod 42 extends inwardly into the sliding groove 101 and is screwed with the connecting hole 301, so that the extrusion rod 30 is driven to move up and down by the rotation of the movable seat 40 through the screwing method. A ball bearing 43 is provided between the mounting seat 10 and the movable seat 40.

[0038] The design focus of the utility model is that: a groove communicating with the through hole is integrally provided on the lower end surface of the clamping piece, and the groove is provided in plurality, and the plurality of grooves separate the lower end of the clamping piece into a plurality of elastic clamping parts; and an extrusion part cooperating with the elastic clamping part is provided at the lower end of the extrusion rod, and the extrusion part pushes the elastic clamping part outward as the extrusion rod slides upward; when taking out the copper washer, it is only necessary to extend the clamping piece into the position of the copper washer in the propeller hub, and then drive the extrusion part to slide upward through the movable seat, so that the elastic clamping part is pushed outward by the extrusion part, and the washer is fixed by the elastic clamping part, so that the washer can be taken out together with the elastic clamping part, and the taking out process is more convenient, and at the same time, the propeller hub will not be scratched.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
