A connecting groove 104 is provided on the cavity wall of the inner cylinder 103, so that during the movement of the telescopic module, the driving source arranged inside the inner cylinder 103 can pass through the connecting groove 104 to drive the several telescopic modules to move synchronously.

[0027] See also Figure 3 and Figure 4 In a preferred embodiment of the present invention, the telescopic module includes a telescopic part assembly 2, and the telescopic part assembly 2 includes a telescopic bin 201, an inner notch 202, a limit opening 203 and an outer notch 204. The telescopic bin 201 is slidably assembled in the main shell 101 along the mold cavity 102. The telescopic bin 201 is also provided with an inner notch 202 on the side facing the inner cylinder 103, and a limit opening 203 is provided at one end of the inner notch 202. An outer notch 204 is arranged on the top of the telescopic bin 201.

[0028] In actual application of this embodiment, the telescopic bin 201 is limitedly slidably assembled in the mold cavity 102, and the telescopic bin 201 and the mold cavity 102 are elastically connected. An inner notch 202 is provided at the bottom of the telescopic bin 201 facing one end of the inner cylinder 103, and the inner notch 202 and the connecting groove 104 are aligned.

[0030] In actual application of this embodiment, the driving rod 301 is fixedly arranged in the main housing 101 along the first direction x, and the driving rod 301 is coaxially fixedly equipped with a traction disk 302 and a limit disk 303, the sliding sleeve 304 is elastically slidably sleeved on the driving rod 301, and the surface of the sliding sleeve 304 is provided with an external tooth groove 305. When the driving rod 301 moves in the negative direction of the first direction x, the limit disk 303 on the end side of the driving rod 301 abuts against the sliding sleeve 304 during the movement, thereby pulling the sliding sleeve 304 to move synchronously in the negative direction of the first direction x, and at this time, it is meshed with the external tooth groove 305. The connected clamping arm assembly 4 is rotated and extended from the telescopic bin 201 in the driven state, and several clamping arm assemblies 4 clamp toward one side of the workpiece during the synchronous rotation, so that the workpiece can be stably clamped between the several clamping arm assemblies 4. When the sliding sleeve 304 moves in the positive direction of the first direction x, several of the clamping arm assemblies 4 are rotated and stored in the telescopic bin 201, and several support arm assemblies 5 slide out from the telescopic bin 201 and abut against the inner wall side of the workpiece to be fixed, thereby forming an internal support clamping structure, which can stably support and fix the component from the inside of the part, and is suitable for processing workpieces that are difficult to clamp with conventional clamps.

[0031] See also Figure 3 and Figure 4 In a preferred embodiment of the present invention, the clamping arm assembly 4 includes a clamping arm 401 and a driven gear disc 402, the clamping arm 401 is rotatably assembled in the telescopic warehouse 201, and one end of the clamping arm 401 is engaged with the external tooth groove 305, and the other end of the clamping arm 401 is fixedly assembled with the driven gear disc 402; the support arm assembly 5 includes a top support arm 501, a guide groove 502, an end rod 503, a top support block 504 and a push block 509, the top support arm 501 is movably arranged in the telescopic warehouse 201, and the top support arm 501 is provided with a guide groove 502, the end rod 503 is fixedly arranged at the front end of the top support arm 501, the top support block 504 is elastically slidably sleeved on the end rod 503, the push block 509 is limitedly slidably assembled in the telescopic warehouse 201, and the push block 509 is rotatably connected to one end of the top support arm 501.

[0032] In actual application of this embodiment, the clamping arm 401 is fixedly rotated and assembled in the telescopic bin 201, and the driven gear disc 402 on the axis side of the clamping arm 401 is engaged with the outer tooth groove 305, so that when the sliding sleeve 304 moves in the positive direction of the first direction x, the clamping arm 401 rotates clockwise in the xoz plane, and when the sliding sleeve 304 moves in the negative direction of the first direction x, the clamping arm 401 rotates counterclockwise in the xoz plane, and the top support arm 501 is movably arranged on the telescopic bin 201. In the inner cavity of the bin 201, a supporting block 504 is elastically slidably sleeved on the end rod 503 at the end of the supporting arm 501. When several supporting arms 501 are extended to the outside of the telescopic bin 201 in the driving state, the supporting block 504 is movably abutted against the inner wall of the workpiece. Since the supporting block 504 is elastically slidably sleeved on the end rod 503, for parts with irregular-sized inner cavities, several supporting blocks 504 can be elastically pressed onto various points in the inner cavity, thereby realizing the internal support fixing function.

[0033] See also Figure 5 In a preferred embodiment of the present invention, the support arm assembly 5 also includes a stop plate 505, a stop tooth 506, a flip rod 507, an axle pin 508 and a locking groove 510.

One end of the flip rod 507 is rotatably assembled in the telescopic bin 201. The other end of the flip rod 507 is fixedly provided with an axle pin 508. The axle pin 508 is limitedly slidably assembled in the guide groove 502. The locking groove 510 is fixedly provided on one side of the outer notch 204.

[0034] When the present embodiment is actually used, the stop plate 505 is slidably assembled on one side of the top support arm 501, and the end of the stop plate 505 is fixedly connected to the top support block 504. One end of the flip rod 507 is rotatably assembled in the telescopic bin 201, and the axle pin 508 at the other end of the flip rod 507 is slidably assembled in the guide groove 502. The locking groove 510 at the end of the top support arm 501 is slidably assembled in the telescopic bin 201. Therefore, when the driving rod 301 moves in the positive direction of the first direction x, the traction disc 302 abuts against one side of the push block 509 and pushes the push block 509 to move in the positive direction of the first direction x, so that the top support arm 501 The support arm 501 moves synchronously, and the axle pin 508 is limited and slidably assembled in the guide groove 502, so that the top support arm 501 rotates clockwise along the xoz plane during the movement, and then the top support arm 501 is rotated out of the inner cavity of the telescopic warehouse 201. When the push block 509 moves to abut against the side of the limit opening 203, the top support arm 501 moves synchronously to the extreme position, and at this time the stopping tooth 506 on the side of the stop plate 505 is movable to abut against the locking groove 510 to limit the sliding of the stop plate 505 on the side of the top support arm 501, thereby putting the top support block 504 in a locked state to ensure stability during internal support.
