Through the setting of the gasket 11, the top end of the narrow end tube 9 can be limited, and when the objective lens 10 in the inner cavity of the narrow end tube 9 is inserted into the inner cavity of the through tube 4, the top end of the objective lens 10 and the inner cavity of the through tube 4 can be padded and protected. Embodiment 2

[0023] Figure 1-4 The utility model shows an easy-to-install pathology scanner objective lens structure of an embodiment of the present invention, which includes: a base 1: a support wall 2 is installed on the top of the base 1, a converter 3 is installed on the top of the inner cavity of the support wall 2, a through tube 4 is connected to the surface of the converter 3, a plurality of holes are opened on the surface of the bottom end of the through tube 4, a ball 5 is connected to the inner cavity of the hole in a rolling manner, a fixing ring 6 is fixedly connected to the surface of the through tube 4, a spring 7 is welded to the bottom end of the fixing ring 6, a sleeve 8 is slidably connected to the surface of the through tube 4, and the inner cavity of the through tube 4 is slidably connected to the inner cavity of the through tube 4. A narrow end tube 9 is connected, a rubber ring 12 is sleeved on the bottom end of the through tube 4, a lens barrel 13 is installed on the top of the supporting wall 2, an eyepiece 14 is installed on the surface of the lens barrel 13, a stage 15 is installed on the top of the base 1, the stage 15 is located just below the objective lens 10, and an operation panel 16 is installed on the right side of the base 1. Through the setting of the rubber ring 12, the surface of the narrow end tube 9 and the bottom end of the through tube 4 are effectively protected to avoid damage to the bottom end of the through tube 4 and the surface of the objective lens 10 after multiple disassembly and assembly.

[0024] Working principle: When the utility model is used, the user places the objective lens 10 into the inner cavity of the narrow end tube 9, and then pushes the sleeve 8 upward, so that the sleeve 8 applies inward pressure to the spring 7 and the inner wall of the sleeve 8 is separated from the surface of the through tube 4. At this time, the top end of the narrow end tube 9 is inserted into the inner cavity of the through tube 4, and then the top end of the narrow end tube 9 pushes the ball 5 to roll to the outside of the through tube 4. When the top end of the narrow end tube 9 contacts the bottom end of the gasket 11, the groove on the top surface of the narrow end tube 9 is parallel to the hole on the surface of the through tube 4, so that the ball 5 falls into the groove on the surface of the narrow end tube 9. At this time, the sleeve 8 is released, and the sleeve 8 is reset under the action of the rebound force of the spring 7, so that the inner wall of the sleeve 8 is re-pressed against the ball 5, and then the installation of the narrow end tube 9 and the through tube 4 is completed, which can facilitate the operator to disassemble and replace the scanner objective lens.

[0025] In summary, the objective lens structure of the pathology scanner which is easy to install is achieved by placing the objective lens 10 into the inner cavity of the narrow end tube 9, then inserting the narrow end tube 9 into the inner cavity of the through tube 4, and then allowing the ball 5 to fall into the groove on the surface of the narrow end tube 9, thereby completing the installation of the narrow end tube 9 and the through tube 4, thereby achieving the purpose of facilitating the operator to disassemble and replace the scanner objective lens.
