[0027] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a sliding shaft retaining spring installation device includes a platform 1, a crossbeam 2 is provided on the platform, and a clamp 3 is provided on the platform for clamping the circumferential outer wall of the shaft body 9; a sleeve 4 is installed on the crossbeam in a liftable manner, including an elastic opening 41, the inner wall of the opening is used to clamp the retaining spring 91, and the opening is used to descend with the sleeve and install the retaining spring into the retaining spring groove 92 on the shaft body; the sleeve is correspondingly arranged above the clamp. The inner wall of the opening clamps the retaining spring, and when the retaining spring is installed, the sliding shaft will open the retaining spring and the opening at the same time. After it is in place, the retaining spring may fall into the retaining spring groove to achieve installation, and then the sleeve can be retreated. The clamp can be a positioning tool such as a three-jaw chuck to fix the sliding shaft.

[0028] In this embodiment, as shown in the figure, the opening is formed by a plurality of elastic spring sheets 411. The spring sheets are integrally arranged with the tube body of the sleeve, and the inner wall of the spring sheets is used to clamp the circumferential outer wall of the clip spring.

[0029] In this embodiment, as shown in the figure, gap grooves 412 are provided between adjacent spring pieces to increase the mobility of the spring pieces.

[0030] In this embodiment, as shown in the figure, the inner wall of the spring sheet is provided with a boss 413, and the boss cooperates with the back of the clip to prevent the clip from retreating when being installed, thus achieving the function of limiting.

[0031] In this embodiment, as shown in the figure, the clamp is a three-jaw chuck.

[0032] In this embodiment, as shown in the figure, the crossbeam is provided with a power source 5 for driving the casing to rise and fall. The power source can be a cylinder or a hydraulic cylinder.

[0033] In this embodiment, as shown in the figure, the power source is a cylinder.

[0034] In this embodiment, as shown in the figure, the power source includes a driving rod 51, and the sleeve is threadedly connected to the driving rod. An external thread is provided on the outer wall of the driving rod, and a nut can be directly welded on the sleeve to cooperate with the external thread, which can facilitate installation.

[0035] In this embodiment, as shown in the figure, the platform is provided with a threaded push rod 6, and the end of the push rod is provided with a tip 61 for contacting the end surface of the bottom of the shaft body. The center positioning is achieved on the center hole at the bottom of the top fixed cutter shaft body to increase the accuracy of installation. The push rod is installed on the mounting plate 15 at the top of the platform, and the mounting plate has a threaded hole, and the push rod is surrounded by an external thread that matches it.

[0036] In this embodiment, as shown in the figure, a guide sleeve 7 is also included which can be detachably mounted on the shaft body, and the guide sleeve is provided with a cone 71 which matches the inner wall of the opening. Some sliding shafts do not have a cone structure at the top, which is inconvenient to install, so the use of the guide sleeve is more conducive to the movement of the sleeve. Of course, if the sliding shaft itself has a cone structure at the tail end, it does not need to be installed.

[0037] In this embodiment, as shown in the figure, the guide sleeve is provided with a plurality of plug-in plates 72 which are engaged with the long slots 94 of the shaft body. The plug-in plates can be inserted into the tail end of the long slots, which is convenient for installation.
