[0026] The slide 4 is fixedly connected with a sleeve seat 5, and the sleeve seat 5 is movably connected with a lubrication seat 6 inside. The lubrication seat 6 is provided with a screw tube 604, and the screw tube 604 is threadedly connected with a screw cap 605. The device is designed with the screw tube 604 and the screw cap 605 to facilitate the filling of grease inside the lubrication seat 6. When the screw cap 605 is tightened on the screw tube 604, the opening position of the screw tube 604 is closed;

[0027] A ball 601 is embedded in the lubrication seat 6, and the ball 601 fits with the screw rod 301;

[0028] A sleeve platform 602 is sleeved on the lubricating seat 6 , a first spring 603 is fixedly connected between the sleeve platform 602 and the lubricating seat 6 , and the sleeve platform 602 is locked with the sleeve seat 5 .

The inner cavity of the lubrication seat 6 is used to store the grease. This lubrication method has a long cycle and a long lubrication time. The grease is evenly applied on the screw rod 301, thereby improving the stability of the screw rod module.

[0031] When the lubrication seat 6 is installed, the position of the sleeve 602 is locked by snapping.
