[0030] Reference Figure 1 - Figure 3The auxiliary installation component includes a discus 31. The lower surface of the discus 31 is provided with a rounded corner 302, which is convenient for inserting into the bushing 2. The outer wall of the discus 31 fits the inner wall of the bushing 2 and can maintain stability. The upper surface of the discus 31 is provided with a slot 301. The inner wall of the slot 301 is plugged with an insert block 32. The outer wall of the insert block 32 fits the inner wall of the slot 301 to avoid deviation. The upper surface of the insert block 32 is fixedly connected to a round rod 33. The outer wall of the round rod 33 is slidably connected to a slide hammer 34. The slide hammer 34 is made of metal and can be moved along the round rod 33. The outer wall moves longitudinally, and in the absence of external force, the slide hammer 34 will fall due to its own gravity. The top of the right surface of the round rod 33 is penetrated and fixedly connected with a handle 35 for easy grasping. A horizontal bubble 5 is installed on the upper surface of the round rod 33. The horizontal bubble 5 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. By observing the position of the horizontal bubble 5, it can be judged whether the device is in a horizontal state. A quick-release assembly is provided inside the discus 31 to facilitate the replacement of the discus 31.

[0031] Reference Figure 1 - Figure 3 The quick-release assembly includes a limiting groove 401. The inner wall of the discus 31 is elastically connected to a positioning block 41 through a compression spring 42. The inner wall on the right side of the positioning block 41 is fixedly connected to a limiting block 43. The limiting groove 401 and the limiting block 43 fit together.

[0032] Reference Figure 1 - Figure 3 The upper surface of the bushing 2 is chamfered, and the lower surface of the bushing 2 is chamfered, which is convenient for preliminary alignment with the mounting groove 101. The discus 31 is inserted into the inner wall of the bushing 2. The upper end of the discus 31 is a disc with a larger diameter, which will be stuck on the upper surface of the bushing 2. The discus 31, the round rod 33, the insert block 32, and the slide hammer 34 are concentric. The middle section of the slide hammer 34 is set to be concave, which is convenient for grasping. The slide hammer 34 can be moved upward more easily, and the lower surface of the insert block 32 fits the inner wall of the bottom end of the discus 31.

[0033] Reference Figure 1 - Figure 3 The limiting groove 401 is opened on the right surface of the insertion block 32, the insertion block 32 passes through the upper surface of the positioning block 41, and a square opening is opened on the positioning block 41. The limiting block 43 is inserted into the inner wall of the limiting groove 401 to limit the insertion block 32. The positioning block 41 passes through and is slidably connected to the left surface of the discus 31. One end of the compression spring 42 is fixedly connected to the right surface of the positioning block 41, and the other end of the compression spring 42 is fixedly connected to the inner wall of the right side of the discus 31. When the positioning block 41 moves to the right, it will squeeze the compression spring 42 to generate a reaction force.

[0034] Working principle: When using this device, first replace the discus 31 of the appropriate model. When replacing, first press the positioning block 41 to the right to drive the limit block 43 to move to the right. The positioning block 41 moving to the right will squeeze the compression spring 42 to generate a reaction force. The limit block 43 moving to the right will disengage from the limit slot 401 to release the limit on the insert block 32. Then grab the handle 35 and move it upward to drive the insert block 32 and the slot 301 to disengage. The disassembly of the discus 31 is completed. Then take out the discus 31 of the appropriate model and put the positioning block on it. 41 is pressed to the right, and the positioning block 41 moving to the right will drive the limiting block 43 to move to the right to remove the obstruction, and the positioning block 41 moving to the right will also squeeze the compression spring 42 to generate a reaction force. After the obstruction is removed, align the plug block 32 with the slot 301 and plug it in. When the plugging is completed, release the positioning block 41, and the reaction force of the compression spring 42 will push the positioning block 41 and the limiting block 43 to move to the left. The limiting block 43 moving to the left will be plugged into the limiting slot 401 to limit the plug block 32, completing the installation of the discus 31.

[0035] Then align the bushing 2 with the mounting groove 101 and place the chamfered part in the mounting groove 101, then insert the discus 31 into the bushing 2 from above, then observe the horizontal bubble 5 and adjust the angle of the device at any time. When the horizontal bubble 5 remains horizontal, stop moving and move the slide hammer 34 upward. Release it when the slide hammer 34 moves to the top. Under the influence of gravity, the slide hammer 34 will move downward and hit the discus 31. The discus 31 will evenly transmit the force to the bushing 2, and the bushing 2 will gradually be inserted into the mounting groove 101. After the bushing 2 completely enters the mounting groove 101, remove the discus 31 from the bushing 2 to complete the installation of the bushing 2.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
