[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, a quick installation tool for the lubricating oil tamper of the upper arm ball stud pin comprises an adjustment rod 1, an upper top fixing cover 2 and a lower top fixing cover 3, wherein the adjustment rod 1 comprises an upper threaded rod 101 and a lower threaded rod 102, an operating head 103 is arranged on the top of the upper threaded rod 101, an outer wall of the upper top fixing cover 2 is provided with an external thread matching the inner wall thread of the upper arm ball stud pin installation tube, the axial center position of the upper top fixing cover 2 is screwed with the upper threaded rod 101, and the center of the lower top fixing cover 3 is screwed with the lower threaded rod 102;

[0024] The upper top cover 2 is screwed into the upper arm ball pin installation tube, the upper threaded rod 101 is screwed and raised at the axis of the upper top cover 2, and the upper top cover 2 is screwed in the upper arm ball pin installation tube in the locking direction.

[0025] A transition rod 104 is provided between the upper threaded rod 101 and the lower threaded rod 102 of the adjusting rod 1, and the diameter of the transition rod 104 is larger than the diameter of the upper threaded rod 101 and the diameter of the lower threaded rod 102;

[0026] The upper top fixing cover 2 includes an external thread section 201 threadedly connected to the inner wall thread of the upper arm ball pin mounting tube, the axis of the external thread section 201 is provided with an internal thread matching the upper threaded rod 101, the bottom side of the external thread section 201 is provided with a support tube 202, the top of the external thread section 201 is provided with an operating head 103 with a through hole, and the operating head 103, the external thread section 201 and the support tube 202 are connected at the top of the external thread section 201;

[0027] The lower top fixing cover 3 includes a cylinder 301, a bottom plate 302 is provided at the bottom of the cylinder 301, a threaded hole 303 matching the lower threaded rod 102 is provided at the center of the bottom plate 302, and a stepped groove 304 is provided on the top of the cylinder 301, which can assist in limiting the installation of the oil naan.

[0028] The operating head 103 is in the shape of a hexagonal head, which is convenient for operation using a hexagonal socket wrench.

[0029] When the utility model is used, Figure 4 As shown, the components are arranged in sequence. First, the ball bushing 1-2 is placed in the upper arm ball pin installation tube 1-1, and the bottom connecting end of the ball bushing 1-2 extends out of the bottom end of the upper arm ball pin installation tube 1-1. The upper top solid cover 1 is screwed into the upper arm ball pin installation tube 1-1 to squeeze and tighten the ball bushing 1-2 to prevent the ball bushing 1-2 from shaking. Then, the upper threaded rod 101 of the adjusting rod 1 is passed through the ball bushing 1-2 and screwed to the internal thread at the axis of the external thread section 201 of the upper top solid cover 2. Then, the oil naan 1-3 is sleeved on the adjusting rod 1, and the lower threaded rod 102 of the adjusting rod 1 is screwed to the threaded hole 303 of the lower top solid cover 3.

[0030] The operating head 103 at the top of the upper threaded rod 101 is operated from the hole at the top of the upper top solid cover 2 to rotate the adjusting rod 1, so that the adjusting rod 1 rises, carrying the lower fixed cover 3 to move the oil naan 1-3 closer to the ball head bushing 1-2, and the lower top solid cover 3 realizes radial support for the oil naan 1-3 until the mounting end of the oil naan 1-3 is buckled on the ball head bushing 1-2. During the rising process of the adjusting rod 1, the upper threaded rod 101 spirally rises in the upper top solid cover 2, driving the upper top solid cover 2 to rise and detach from the upper arm ball head pin mounting tube 1-1. However, since the upper top solid cover 2 is threadedly connected to the inner wall of the upper arm ball head pin mounting tube 1-1, the rising rotation direction of the upper top solid cover 2 is the locking direction of the threaded connection with the inner wall of the upper arm ball head pin mounting tube 1-1.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
