Four supporting mechanisms 4 are installed between the four expansion mechanisms 3 and the support spindle 101, and four locking mechanisms 5 are provided on the four supporting mechanisms 4;

[0041] The driving mechanism 2 is used to provide power to the expansion mechanism 3 by using the pressure between the driving mechanism 2 and the template;

[0042] The expansion mechanism 3 is used to expand the support range of the support spindle 101 to the template by using the power provided by the driving mechanism 2;

[0044] The locking mechanism 5 is used to lock the extended supporting mechanism 4 .

[0045] In one embodiment, the driving mechanism 2 includes a pressure plate 201, a connecting shaft 202, a first piston plate 203, an air storage chamber 204 and a first spring 205;

[0046] The air storage chamber 204 is provided in the middle of the inner side wall of the supporting main shaft 101, the pressure plate 201 is provided above the supporting main shaft 101, one end of the connecting shaft 202 is fixedly connected to the bottom of the pressure plate 201, the other end of the connecting shaft 202 is fixedly connected to the upper surface of the first piston plate 203, the outer side walls of the first piston plate 203 and the connecting shaft 202 are both slidably connected to the inner side wall of the air storage chamber 204, and the first spring 205 is fixedly connected between the bottom of the inner side wall of the air storage chamber 204 and the lower surface of the first piston plate 203;

[0047] The pressure-bearing plate 201 drives the connecting shaft 202 and the first piston plate 203 to move under the action of pressure, and the moving first piston plate 203 squeezes the air in the air storage chamber 204 .

[0048] In one embodiment, the four expansion mechanisms 3 each include an expansion plate 301 , a piston sleeve 302 , a second piston plate 303 and a connecting rod 304 ;

[0049] The piston sleeve 302 is fixedly connected to the inner wall of the supporting spindle 101 and communicates with the air storage chamber 204.

[0050] The air pressure in the air storage chamber 204 and the piston sleeve 302 is used to drive the second piston plate 303 to move. The moving second piston plate 303 drives the expansion plate 301 to slide at the bottom of the template using the connecting rod 304 to expand the supporting range of the support box frame 102. The moving expansion plate 301 is guided by the set guide rod 63.

[0051] In one embodiment, the four supporting mechanisms 4 each include a supporting sleeve 401 , a supporting slide bar 402 and two connecting blocks 403 ;

[0052] The outer wall of the supporting slide bar 402 is slidably connected to the inner wall of the supporting sleeve 401, and two connecting blocks 403 are respectively fixedly connected to the supporting sleeve 401 and one end of the supporting slide bar 402, and the two connecting blocks 403 are respectively hinged to the bottom of the expansion plate 301 and the outer wall of the supporting main shaft 101;

[0053] The support slide bar 402 is driven to move by the expansion plate 301 so as to slide in the support sleeve 401 .

[0054] In one embodiment, the four locking mechanisms 5 each include a limit frame 501, a threaded knob 502, a push plate 503, a second spring 504, a pin block 505 and a rack 506;

[0055] Among them, the limit frame 501 is fixedly connected to one side of the supporting sleeve 401, the outer wall of the threaded knob 502 is threadedly connected to the inner wall of the limit frame 501, the push plate 503 is slidably connected to the inner wall of the limit frame 501, one end of the threaded knob 502 is rotatably connected to one side of the push plate 503, the pin block 505 is slidably connected to one side of the inner wall of the limit frame 501, the second spring 504 is fixedly connected between the pin block 505 and the push plate 503, the rack 506 is fixedly connected to the outer wall of the supporting slide rod 402, the outer wall of the rack 506 is slidably connected to the inner wall of the supporting sleeve 401, and one side of the pin block 505 is meshedly connected to one side of the rack 506;

[0056] The supporting slide bar 402 drives the rack 506 to slide in the supporting sleeve 401 , and the moving rack 506 presses one side of the pin block 505 , so that it drives the second spring 504 to be compressed and slide into the limiting frame 501 .

[0057] In one embodiment, a threaded portion 61 is provided at the bottom of the support spindle 101, a support plate 62 is evenly fixedly connected to the top of the outer wall of the support spindle 101, and one side of the support plate 62 is fixedly connected to the bottom of the support box frame 102;

[0058] The contact area between the support spindle 101 and the support housing 102 is pressurized by using the support plate 62 .

[0059] When the utility model is in operation, according to actual needs, the handle 103 is rotated to drive the support main shaft 101 to use the threaded portion 61 to install the entire device.

[0060] When the installation is completed, the pressure plate 201 is driven to squeeze the template by moving the support main shaft 101 and the support box frame 102, so that the connecting shaft 202 and the first piston plate 203 are driven to move under the action of pressure. The moving first piston plate 203 presses the air in the air storage chamber 204 into the piston sleeve 302, and drives the first spring 205 to be compressed. Then, the air pressure in the air storage chamber 204 and the piston sleeve 302 is used to drive the second piston plate 303 to move. The moving second piston plate 303 uses the connecting rod 304 to drive the expansion plate 301 to slide at the bottom of the template to expand the support range of the support box frame 102. The moving expansion plate 301 drives the guide rod 63 and the supporting slide bar 402 to move. The moving guide rod 63 slides in the supporting box frame 102 to guide the moving expansion plate 301. The moving supporting slide bar 402 drives the rack 506 to slide in the supporting sleeve 401. The moving rack 506 squeezes one side of the pin block 505, so that it drives the second spring 504 to be compressed and slide into the limit frame 501 to prevent the pin block 505 from interfering with the movement of the rack 506.

[0061] When the pressure plate 201 is flush with the top of the supporting box frame 102, the pin block 505 is driven by the compressed second spring 504 to be inserted into the rack 506 to lock the supporting sleeve 401 and the supporting slide bar 402 so that the supporting sleeve 401 and the supporting slide bar 402 can be used to support the bottom of the expanded plate 301 after unfolding.

[0062] When the support work is completed and the device needs to be dismantled, first remove the bottom of the device template, then turn the threaded knob 502 to use the thread to drive the push plate 503 to slide in the limit frame 501, and the sliding push plate 503 drives the second spring 504 to stretch, so that the stretched second spring 504 can be used to drive the pin block 505 to separate from the rack 506, so as to release the lock between the supporting sleeve 401 and the supporting slide bar 402, and then repeat the operation to release the lock between all the supporting sleeves 401 and the supporting slide bar 402, and then use the compressed first spring 205 to push the first piston plate 203 to reset, so as to draw the air in the piston sleeve 302 back to the inside of the air storage chamber 204, and reset the expansion plate 301 as a whole, so that the device can be reused.

[0063] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
