[0028] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below.

[0029] In order to solve the problems existing in the background art, this application proposes the following technical solution: a telescopic support for vehicle maintenance, including: a fixed shell 1, a telescopic support rod 2 and a positioning component 7.

[0030] In specific technical implementations, such as Figure 4As shown, a receiving groove is provided inside the fixed shell 1, and the telescopic support rod 2 is locked in the receiving groove. A connecting rod 3 is installed in the receiving groove. A connecting groove 4 is opened at the bottom of the telescopic support rod 2, and the connecting rod 3 is locked in the connecting groove 4. A receiving groove 5 is opened inside the connecting rod 3. A compression spring 6 is installed between the bottom of the inner wall of the receiving groove 5 and the top of the inner wall of the connecting groove 4. The compression spring 6 can limit the telescopic support rod 2. When it needs to be extended, the compression spring 6 can push the telescopic support rod 2 outward by its elastic force, thereby automatically and quickly extending the service length of the support.

[0031] In specific implementations, such as Figure 4 and Figure 5 As shown, the positioning assembly 7 is used to position the telescopic support rod 2. The positioning assembly 7 includes a mounting cylinder 701, a mounting block 702, a control rod 703, a positioning pin 704, and a limiting spring 705. The mounting cylinder 701 and the mounting block 702 are both installed on one side of the fixed shell 1 from top to bottom. The bottom of the mounting cylinder 701 has a through-hole 8. The center position of the control rod 703 is installed in the mounting block 702 through a rotating shaft, and one end of the control rod 703 passes through the through-hole 8 and is set in the mounting cylinder 701. Therefore, the control rod 703 can be rotated and adjusted from below within the mounting cylinder 701. Positioning pin 704 is installed on one side of control rod 703. A through-hole 8 is provided on the fixed shell 1. Multiple keyways 9 corresponding to the through-hole 8 are provided on one side of telescopic support rod 2. One end of positioning pin 704 passes through the through-hole 8 and is locked in the keyway 9. The telescopic support rod 2 can be positioned from one side by the cooperation of positioning pin 704 and keyway 9. Limiting spring 705 is installed between control rod 703 and the inner wall of mounting cylinder 701. Therefore, limiting spring 705 can limit control rod 703 and positioning pin 704, thereby ensuring stable positioning.

[0032] Furthermore, the height of the through port 8 is greater than the height of the positioning pin 704. Since the control rod 703 drives the positioning pin 704 to make circular motion, the through port 8 can provide sufficient movement space for the positioning pin 704.

[0033] Furthermore, the top of one end of the positioning pin 704 located inside the keyway 9 is provided with a contact arc surface 10, which ensures that the positioning pin 704 can be automatically pushed to move when the telescopic support rod 2 retracts, and the contact arc surface 10 ensures that the positioning pin 704 can be smoothly rotated out of the keyway 9.

[0034] Before use, one end of the positioning pin 704 is locked in the keyway 9, thus fixing the telescopic support rod 2. When extended support is needed, push the control rod 703 inward from below. The control rod 703 rotates around its pivot, pressing the limiting spring 705 above and rotating. At the same time, the positioning pin 704 can rotate out of the keyway 9. Then, the telescopic support rod 2 can automatically and quickly pop out under the elastic force of the limiting spring 705. Then, release the control block 1601, and the positioning pin 704 can be inserted back into the corresponding keyway 9. Alternatively, press down on the telescopic support rod 2 to insert the positioning pin 704 into the keyway 9 at the appropriate position, which can fix the telescopic support rod 2 again. Then, it can be used for support.

[0035] In specific implementations, such as Figure 2 As shown, a fixing plate 11 is installed on the front side of the fixing shell 1. The fixing plate 11 is connected to a reinforcing pin 12 through an installation line. Multiple fixing holes 13 are opened on the telescopic support rod 2. Through holes 14 communicating with the fixing holes 13 are opened on both sides of the fixing shell 1. The reinforcing pin 12 is locked in the fixing holes 13 and through holes 14, so the telescopic support rod 2 can be fixed from the other side. This ensures that the telescopic support rod 2 is stable after the position is adjusted, and prevents the telescopic support rod 2 from popping out automatically, thus providing a protective effect.

[0036] In specific implementations, such as Figures 4-6 As shown, a mounting head 15 is installed at one end of the reinforcing pin 12. An anti-drop component 16 is provided inside the mounting head 15 and the reinforcing pin 12 to prevent the reinforcing pin 12 from falling off. The anti-drop component 16 includes a control block 1601, a mounting flap 1602, a mounting spring 1603, and a spring button 1604. An inner cavity 17 is formed inside the reinforcing pin 12 and the mounting head 15. A control groove 18 is formed between the inner cavity 17 and the outer wall of the mounting head 15. A slot 19 is formed between the inner cavity 17 and the outer wall of the reinforcing pin 12. The control block 1601 is fitted into the control groove 18. The mounting spring 1603 is installed between the control block 1601 and the inner wall of the inner cavity 17. The mounting spring 1603 can limit the control block 1601. The mounting tab 1602 is installed on the control block 1601 and is attached to the inner wall of the inner cavity 17. The spring button 1604 is installed on the mounting tab 1602 and is fitted into the slot 19. The fixing shell 1 is located between the mounting head 15 and the spring button 1604.

[0037] When it is necessary to remove the reinforcing pin 12, press the control block 1601. The control block 1601 can squeeze the mounting spring 1603 and move it inward. At the same time, the control block 1601 can drive the mounting flap 1602 to move. The spring button 1604 can move into the slot 19 and the inner cavity 17. When the spring button 1604 is fully inserted into the slot 19 and the inner cavity 17, the reinforcing pin 12 is no longer fixed on the fixing shell 1, and then the reinforcing pin 12 can be removed directly.

[0038] Furthermore, the distance between the end of the spring button 1604 and the outer wall of the reinforcing pin 12 is less than the distance between the mounting flap 1602 and the inner wall of the inner cavity 17.
