[0032] Reference Figure 3 - Figure 5The fixing assembly 5 also includes a support plate 52 for supporting a fixing sleeve 54. The top of the support plate 52 is fixedly connected to the bottom end of the spring telescopic rod 51. The top of the support plate 52 is provided with an extrusion groove 53 for the output end of the hydraulic press 4 to pass through. The extrusion groove 53 is adapted to the hydraulic press 4. The hydraulic press 4 is a prior art and can start working when the power is turned on. It can be implemented by personnel in this field. Due to the prior art, this case will not be described in detail. The bottom end of the support plate 52 is fixedly connected with a fixing sleeve 54 for accommodating a transmission shaft 61. The inner wall of the fixing sleeve 54 is slidably connected with an extrusion block 55 for extruding the transmission shaft 61. The extrusion block 55 is made of rubber and will undergo elastic deformation when squeezed. Its surface is relatively rough and can provide greater friction when in contact with the transmission shaft 61. The transmission 6 includes a transmission shaft 61. The transmission shaft 61 is inserted into the inner wall of the fixing sleeve 54. The top of the transmission shaft 61 is inserted with a rotating shaft 62 for connecting the overall transmission 6. The overall transmission 6 can be disassembled by removing the rotating shaft 62.
