[0023] Please see Figure 1 , Figure 3The locking mechanism 8 includes a fixed seat 81. The fixed seat 81 is rotatably sleeved on the outside of the rotating seat 7 via a bearing. The fixed seat 81 is fixedly connected to the top plate 3. A groove 82 is formed inside the fixed seat 81. A retaining ball 83 is movably sleeved inside the groove 82. There are multiple grooves 82, which are arranged in a ring and evenly distributed inside the fixed seat 81. By designing multiple grooves 82, the retaining ball 83 can roll into the grooves 82 at different positions. The retaining ball 83 is movably connected to the rotating seat 7. The outer side of the retaining ball 83 is movably sleeved. A connecting block 84 is slidably connected to the rotating seat 7. A connecting rod 85 is slidably connected inside the connecting block 84. The connecting rod 85 is fixedly connected to the rotating seat 7. A second spring 86 is provided on the outside of the connecting rod 85. One end of the second spring 86 is fixedly connected to the connecting block 84, and the other end of the second spring 86 is fixedly connected to the rotating seat 7. By designing the second spring 86, the force of the second spring 86 can be applied to the connecting block 84. By designing the locking mechanism 8, it is convenient to lock the position of the rotating drum 10.

[0024] Please see Figure 1 , Figure 4 The connecting mechanism 9 includes a plug rod 91, which is fixedly connected to the top of the bracket 15. The plug rod 91 is slidably connected to the connecting post 11. An inclined groove 92 is opened inside the plug rod 91, and an inclined block 93 is slidably connected inside the inclined groove 92.

One end of the third spring 96 is fixedly connected to the support block 94, and the other end of the third spring 96 is fixedly connected to the connecting post 11. By designing the third spring 96, the force of the third spring 96 can be applied to the support block 94. A ball 97 is fixedly connected to the outside of the support block 94. The ball 97 is fixedly connected to the connecting post 11. By designing the connecting mechanism 9, it is convenient to replace the pressure head 16.

[0025] The specific implementation process of this utility model is as follows: When it is needed for pressing, the hydraulic cylinder 4 is started. The output end of the hydraulic cylinder 4 drives the pressing block 5 to move down. The pressing block 5 will slide into the inside of the rotating cylinder 10 and press down on the connecting column 11. The connecting column 11 will drive the slider 12 to slide along the fixed rod 13 to squeeze the first spring 14. At the same time, the connecting column 11 will drive the bracket 15 and the pressing head 16 to move down to perform pressing.

[0026] When it is necessary to switch the use of the pressure head 16, start the motor 6. The output end of the motor 6 drives the rotating seat 7 to rotate, and the rotating seat 7 drives the rotating drum 10 to rotate, thereby changing the position of the pressure head 16. This allows for convenient and flexible switching between different pressure heads 16 for pressing and improving the applicability of the device.

[0027] When the rotating seat 7 rotates, it drives the retaining ball 83 to rotate. The retaining ball 83 rolls along the arc surface of the groove 82. The retaining ball 83 is squeezed and pushed to roll outward. The retaining ball 83 drives the connecting block 84 to slide along the connecting rod 85. The connecting block 84 squeezes the second spring 86, which can separate the retaining ball 83 from the groove 82. When the rotating seat 7 stops rotating, the elastic action of the second spring 86 will give the connecting block 84 an outward push force, which can push the retaining ball 83 into the groove 82 in another position. At this time, the rotating seat 7 and the rotating cylinder 10 can be limited, which in turn can limit the pressure head 16, so as to avoid the shaking of the pressure head 16 during pressing and affect the pressing effect.

[0028] When it is necessary to disassemble the pressure head 16, simply pull down the bracket 15. The bracket 15 will cause the insertion rod 91 to move down. The inclined surface of the inclined groove 92 inside the insertion rod 91 can squeeze the inclined block 93, causing the inclined block 93 to move horizontally. At the same time, the inclined block 93 drives the support block 94 to slide along the guide rod 95 to squeeze the third spring 96. Simultaneously, the support block 94 can squeeze the ball 97, which can separate the inclined block 93 from the insertion rod 91. Then the insertion rod 91 can be pulled out from the inside of the connecting column 11, which is convenient for disassembling the pressure head 16 and for maintaining the pressure head 16. At the same time, different models of pressure heads 16 can be replaced according to usage requirements.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
