Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 - Figure 6 , the utility model provides a technical solution:

[0035] In this embodiment, it is considered that the output shaft 3 of the existing gearbox housing 2 lacks reinforced support, and the output shaft 3 is prone to shaking during rotation, affecting normal transmission. At the same time, the shaking also aggravates the wear of the output shaft 3, thereby reducing the practicality of the gearbox housing 2. Therefore, by setting a reinforced support mechanism, the threaded rod 12 can be driven to rotate by rotating the twisting block 11. When the threaded rod 12 rotates, the external thread on its surface will squeeze the internal thread of the threaded hole 13, so that the support block 7 and the U-shaped block 8 move upward, and the U-shaped block 8 will drive the roller 9 to move upward, so that the surface of the roller 9 contacts the surface of the output shaft 3, thereby achieving the effect of strengthening the support. At the same time, the roller 9 can rotate around the rotating shaft 10 without affecting the normal rotation of the output shaft 3.

[0036] The problem that the output shaft 3 of the existing gearbox housing 2 lacks reinforced support and is prone to shaking during rotation, affecting normal transmission, and the shaking also aggravates the wear of the output shaft 3, thereby reducing the practicality of the gearbox housing 2 is solved.

[0037] Preferably, sliding blocks 23 are fixedly connected to both sides of the telescopic block 5 , and a sliding groove 24 for use with the sliding block 23 is formed on the inner wall of the telescopic hole 4 .

[0038] In this embodiment, by providing the sliding block 23 and the sliding groove 24, the telescopic block 5 can be restricted to move only along the track of the sliding groove 24 and the sliding block 23 in the telescopic hole 4. At the same time, the design of the sliding block 23 and the sliding groove 24 can also improve the stability of the telescopic block 5.

[0039] Embodiment 2:

[0040] On the basis of Example 1, the strengthened support mechanism in this embodiment can support the gearbox case 2 and enhance the rotation stability of the output shaft 3. However, considering that the length of the output shaft 3 in the gearbox case 2 is different according to different usage scenarios, if the position supported by the strengthened support mechanism is not suitable, it will also affect the stability of the support. The adjustment mechanism in this application includes a shell 14 fixedly connected to one side of the base 1, a movable block 15 is provided inside the shell 14, a positioning rod 16 is fixedly connected to the bottom of the movable block 15, and a plurality of positioning holes 17 used in conjunction with the positioning rod 16 are opened on the top of the telescopic block 5. A driving rod 18 is fixedly connected to one side of the movable block 15, and one end of the driving rod 18 passes through the outside of the shell 14 and is fixedly connected to a driving block 19.

[0041] In this embodiment, it is considered that the length of the output shaft 3 in the gearbox housing 2 is set differently according to different usage scenarios. If the position of the support of the reinforced support mechanism is not suitable, it will also affect the stability of the support. Therefore, by setting an adjustment mechanism, the driving block 19 can be pushed upward, and the driving block 19 drives the driving rod 18 and the movable block 15 to move upward along the trajectory of the driving groove 21. The movable block 15 will drive the positioning rod 16 to leave the positioning hole 17. After that, the telescopic block 5 can be pulled to adjust the position of the sleeve 6 and the reinforced support mechanism. When it reaches the appropriate position, the driving block 19 is released, and the elastic force generated by the spring 20 will push the movable block 15 to move downward, and the movable block 15 will drive the positioning rod 16 to enter the corresponding positioning hole 17, completing the adjustment of the sleeve 6 and the reinforced support mechanism, so that the reinforced support mechanism is in an adapted position to support the output shaft 3, further improving the stability of the reinforced support;

[0042] The problem that the output shaft 3 in the gearbox housing 2 has different lengths according to different usage scenarios and that the stability of the support may be affected if the position of the support mechanism is not suitable is solved.

[0043] Preferably, a spring 20 is fixedly connected to the top of the movable block 15 , and the top of the spring 20 is fixedly connected to the inner wall of the housing 14 .

[0044] In this embodiment, the spring 20 is provided so that when the driving block 19 is released, the elastic force generated by the spring 20 can push the movable block 15 and the positioning rod 16 upward, so that the positioning rod 16 enters the corresponding positioning hole 17, thereby achieving a reset effect.

[0045] Preferably, a driving groove 21 is formed on one side of the housing 14 , and the driving groove 21 cooperates with the driving rod 18 for use.

[0046] In this embodiment, the driving groove 21 is provided to provide a moving track for the driving rod 18 , and the paper driving rod 18 can only move up and down along the driving groove 21 .

[0047] Preferably, a bearing 22 is provided on the top of the twisting block 11 , and the twisting block 11 is rotatably connected to the bottom of the sleeve 6 via the bearing 22 .

[0048] In this embodiment, the bearing 22 is provided to support and limit the twisting block 11 so that the twisting block 11 can only rotate, and the rotation stability of the twisting block 11 can be improved.

[0049] Working principle: The user rotates the twisting block 11 to drive the threaded rod 12 to rotate. When the threaded rod 12 rotates, the external thread on its surface squeezes the internal thread of the threaded hole 13, so that the support block 7 and the U-shaped block 8 move upward. The U-shaped block 8 drives the roller 9 to move upward, so that the surface of the roller 9 contacts the surface of the output shaft 3, thereby achieving the effect of strengthening the support. At the same time, the roller 9 can rotate around the rotating shaft 10 without affecting the normal rotation of the output shaft 3.

[0050] Alternatively, by pushing the driving block 19 upward, the driving block 19 drives the driving rod 18 and the movable block 15 to move upward along the trajectory of the driving groove 21, and the movable block 15 drives the positioning rod 16 to leave the positioning hole 17, and then the telescopic block 5 can be pulled to adjust the position of the sleeve 6 and the reinforced support mechanism to the appropriate position, release the driving block 19, and the elastic force generated by the spring 20 will push the movable block 15 to move downward, and the movable block 15 will drive the positioning rod 16 to enter the corresponding positioning hole 17, completing the adjustment of the sleeve 6 and the reinforced support mechanism, so that the reinforced support mechanism is in an adaptive position to support the output shaft 3, thereby further improving the stability of the reinforced support.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
