No.

The two pillars 3 are connected in parallel between the two seats 2, 2', respectively. More specifically, each of the pillars 3 is disposed in parallel with each other and is vertically connected to the two bases 2, 2', and the two pillars 3 are positionally stretchable to the two seats 2, 2 In between, each of the struts 3 includes a tubular member 31 and a rod member 32 that is movably and positionally insertable in the tubular member 31. Preferably, a first elastic member 311 is further disposed in the tubular member 31 to provide an auxiliary force for the telescopic movement of the member 32, thereby increasing the operation smoothness and flexibility of the member 32. It can be understood that the telescopic structure of the two pillars 3 can be, but is not limited to, the combination of the tube member 31 and the rod member 32, such as a telescopic rod and a slide rail. Etc., the components that provide such effects are not necessary.

In addition, as shown in FIG. 3 , a positioning component 33 is further disposed on the tube member 31 . The rod member 32 has a plurality of positioning structures 321 , and the positioning assembly 33 includes a radially adjustable positioning member 331 . The positioning member 331 can be adjusted. The positioning member 33 further includes a fixing seat 332 detachably disposed at one end of the tube member 31. The rod member 32 is inserted through the fixing base 332 and then inserted. The positioning member 331 is disposed in the fixing member 332 in the radial direction. In more detail, the positioning member 331 is a rod member, one end is in a shape that is in abutment with the positioning structure 321 and is mutually positioned, and the other end is in a holding portion, which provides convenient operation and adjustment effect, and the positioning member Preferably, a second elastic member 333 is disposed between the 331 and the fixing base 332. The second elastic member 333 provides a radial displacement assisting force of the positioning member 331, so that the positioning member 331 can be normally radial. The grounding member 321 is biased against the positioning structure 321 to ensure the positioning of the positioning member 331 and the positioning structure 321 to each other. It should be noted that the positioning component 33 can be, but is not limited to, the structure shown in this embodiment. Any structure that can provide an adjustment positioning function can be applied.

4A and 4B, the present invention further provides a ball joint disassembly tool, comprising a ball joint disassembly tool component as described above, further comprising a cylinder member 4, the cylinder member 4 in operation is located on the opposite side of the screw 22 and abuts against the seat body 2' and the annular socket portion 11, in more detail, the cylinder member 4 is provided with a receiving groove 41, a pressing member 50 and Provided between the screw 22 and the ball head 12, preferably, the pressing member 50 has a concave surface corresponding to the surface of the ball head 12, so as to improve the stability of the support between the ball head 12 and Damage to the ball head 12 can be avoided. It can be understood that the pressing member 50 can be a single unitary member or can be integrally formed at one end of the screw 22. The pocket 41 allows the ball head 12 to be ejected into it. It should be noted that the tubular member 4 can also be designed as a radially expandable structure that can be positioned, such that The two pillars 3 adjust the distance between the two seats 2, 2', and the cylinder member 4 can be adjusted according to various ball joints of different sizes, thereby increasing the adjustable range of the ball joint disassembly tool. It is worth mentioning that the tube member 31 and the seat body 2' can be detachably replaced with suitable members by being configured to cooperate with each other.

Please further refer to FIG. 5, which shows another embodiment of the ball joint dismounting tool of the present invention. Compared with the embodiment described above, one end of the tubular member 4' of the embodiment is provided with a screw portion 43. The screw portion 43 can be screwed with the screw hole 21', so that the cylindrical member 4' can be stably disposed without being easily detached when the ball head 12 is erected, and replaced with a suitable size as needed. Another adjustment function can be provided, which further increases the adjustable range of the ball joint disassembly tool. In addition, the tubular member 4' can also be designed as a radially expandable structure that can be positioned, further increasing the adjustable range of the ball joint disassembly tool. Therefore, when the screw 22 and the seat body 2' respectively provide abutting action on the opposite sides of the annular socket portion 11 to the ball head 12 and the annular socket portion 11, the two pillars 3 Or / and the tubular member 4 can be adjusted to match the size of the ball joint 1, so that the annular socket portion 11 is fixed between the opposite two seats 2, 2' and the two pillars 3, and the forced The pressing member 50 abuts between the ball joint 1 and the screw 22, and then presses the screw 22 toward the pressing member 50 with a force, so that the pressing member 50 is pushed by the force. The ball joint 1 is thus separated from the annular socket portion 11.

Referring to FIGS. 6A and 6B, there is shown a schematic view of a mounting sleeve according to another embodiment of the present invention. A pressing member 50' and a tubular member 4 respectively abut the annular socket portion 11 and the ball head 12, and the ring The socket portion 11 and the ball head 12 abut against each other. Actuating the screw 22 in the direction of the pressing member 50' to urge the pressing member 50' toward the side of the annular socket portion 11, the ball head 12 can be inserted into the In the annular socket portion 11. Thereby, the original separation of the ring can be conveniently and quickly The socket portion 11 and the ball head 12 are combined to form a ball joint.

In summary, the ball joint disassembly tool of the present invention and its components can be flexibly telescopically adjusted and fixed to fit various sizes through the two telescopic pillars, the retractable cylinder member and/or the screwable cylinder member. The ball joint can quickly reach the position of the top ball joint and can greatly reduce the operation time, and the conventional structure can only slowly reach the problem of the top ball joint by rotating the screw, and the ball joint disassembly and assembly The structure and components of the tool and its components are simple, easy to manufacture and assemble.

Moreover, the opposing seat body and the tubular member can be designed to be detachably assembled, and can be appropriately replaced as needed, and the compatibility and applicability are extremely wide.

In summary, the present invention provides a ball joint disassembly tool and a component thereof, which is compact and practical in structure, and can provide a user with a ball joint adjustment according to different sizes, and can provide a variety of tool combinations for the manufacturer. To enhance the competitiveness of the product, the user can adjust or/or replace the parts of the tool according to the size of the ball joint without additional payment of the purchase fee, which is quite convenient and is highly effective in complying with the patent law. It is stipulated that, in the case of filing a patent application in accordance with the law, it is really sensible to ask the bureau to approve the patent as soon as possible.
