DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.

[0020] Embodiment 1

[0021] See also Figure 1-Figure 2The utility model provides a technical solution: a shift shaft fixing bracket, comprising: a workbench 1, a symmetrical outer slide groove 2 is opened on the upper surface of the workbench 1, the outer slide groove 2 runs through a side wall of the workbench 1, and first sliders 12 are slidably connected in the two outer slide grooves 2. There are four first sliders 12, two of which are a pair and symmetrically arranged, and the first sliders 12 can be taken out from their side walls. A clamping device 3 is arranged on each of the two symmetrical first sliders 12, and the clamping device 3 is used to clamp the shift shaft. The clamping device 3 includes a clamping plate 21, a clamping block 5 and a first threaded rod 7. The clamping plate 21 is fixedly installed on the upper surface of the first slider 12 The surface of the clamping plate 21 is provided with a recess 10, and the clamping block 5 is arranged in the recess 10. The first threaded rod 7 passes through the side wall of the recess 10 and is threadedly connected thereto. One end of the first threaded rod 7 is rotatably connected to the clamping block 5, and the other end of the first threaded rod 7 is fixedly installed with a crank 6. The clamping block 5 can be clamped and loosened by turning the crank 6. A first curved surface 8 is provided on one side of the clamping block 5, and a second curved surface 11 is provided on one side of the recess 10. The first curved surface 8 and the second curved surface 11 are arranged opposite to each other. The first curved surface 8 and the second curved surface 11 are intended to prevent the shift shaft from slipping during clamping.

[0022] Since the outer slide groove 2 passes through one side wall of the workbench 1, the two clamping devices 3 can be removed together with the two first sliding blocks 12. They can be clamped first, and then inspected and observed by holding the clamping block. Inspection and observation at multiple angles are possible. When maintenance is required, the clamped shift shaft fixing bracket can be installed on the workbench 1. During the clamping process, the crank 6 can be shaken to clamp and release it. After clamping, the shift shaft will contact the first arc surface 8 and the second arc surface 11.

[0023] Embodiment 2

[0024] See also Figure 3-Figure 4 On the basis of the first embodiment, inner grooves 20 are provided on both sides of the inner wall of the outer groove 2, and second slide blocks 13 are fixedly installed on both sides of the first slide block 12. The second slide block 13 is slidably connected to the inner groove 20, and the second slide block 13 can be removed from the workbench 1 together with the first slide block 12. A torsion block 4 is provided above the clamping plate 21, and a second threaded rod 15 is fixedly connected to the lower surface of the torsion block 4. The second threaded rod 15 penetrates the clamping plate 21 and the first slide block 12 and is rotatably connected to the disc 14. The disc 14 is normally embedded in the bottom wall of the first slide block 12. When the slide block needs to be fixed, the torsion block 4 is rotated, and the torsion block 4 drives the second threaded rod 15 to rotate. The rotation of the second threaded rod 15 will drive the disc 14 to move downward relative to the first slide block 12. Because of the existence of the second slide block 13, the first slide block 12 cannot move up and down, and only the disc 14 moves downward, and the first slide block 12 is fixed by the disc 14 and the second slide block 13.

[0025] When it is necessary to fix the first slider 12 and the clamping device 3 on the first slider 12, select a suitable position and then rotate the twist block 4 so that the disc 14 contacts the bottom plate of the outer slide groove 2 and generates a certain pressure. At this time, pressure will also be generated between the second slider 13 and the inner slide groove 20. Then, tighten the twist block 4 to increase the pressure between the second slider 13 and the inner slide groove 20 and between the disc 14 and the bottom plate of the outer slide groove 2, making it difficult to slide casually. In this way, the entire clamping device 3 can be tightly fixed on the workbench 1.

[0026] Embodiment 3

[0027] See also Figure 4 On the basis of the second embodiment, an oil drain groove 9 is opened between the two outer slide grooves 2. During the maintenance process, it is necessary to clean the oil stains or add lubricating liquid, etc. These substances may fall into the oil drain groove 9. The bottom of the oil drain groove 9 is set as an inclined surface 19. The setting of the inclined surface 19 can make the liquid falling into the oil drain groove 9 move in one direction. A square opening 18 is opened on one side of the oil drain groove 9. The square opening 18 is connected to the oil drain groove 9. Finally, the liquid falling into the oil drain groove 9 will flow out along the square opening 18, and a container can be used to catch it under the square opening 18 for further processing.

[0028] In actual use, first choose whether to remove the clamping device 3 to clamp the shift shaft according to the actual situation. During the clamping process, the crank 6 can be shaken to clamp and loosen it. After clamping, the shift shaft will contact the first curved surface 8 and the second curved surface 11. When fixing the clamping device 3, select a suitable position and then rotate the twist block 4 so that the disc 14 contacts the bottom plate of the outer slide groove 2 and generates a certain pressure. At this time, pressure will also be generated between the second slider 13 and the inner slide groove 20. Then tighten the twist block 4 to increase the pressure between the second slider 13 and the inner slide groove 20 and the disc 14 and the bottom plate of the outer slide groove 2, making it difficult to slide casually. In this way, the entire clamping device 3 can be tightly fixed on the workbench 1.

[0029] Although the 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.
