[0008] Preferably, the fixed limiting device arranged at the other end of the two front-end adjustment slot blocks and one end of the rear-end adjustment slot block includes a first clamping block, the first clamping block is connected and fixed to the front-end adjustment slot block, the bottom of the first clamping block is slidably connected to the second clamping block, the second clamping block is connected and fixed to one end of the rear-end adjustment slot block, the first clamping block and the second clamping block are both equidistantly provided with clamping holes, and one of the clamping holes is slidably clamped to the clamping block.

[0009] Preferably, the clamping block includes a pressing block, the top of the pressing block is connected and fixed to one end of the sliding block, the other end of the sliding block is provided with rectangular grooves equidistantly arranged in a ring shape, the outer ring of the other end of the sliding block is respectively connected and fixed to the inner ring of an arc block, and the outer ring of the sliding block is slidably connected to the inner ring of the clamping hole.

[0010] Preferably, the edges of the clamping holes of the first clamping block and the second clamping block that are opposite to each other are provided with inclined surfaces.

[0011] Preferably, the edges of the front-end adjustment slot block and the rear-end adjustment slot block are both rounded.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Since the bottom of the first clamping block is slidably connected with the second clamping block during adjustment, when the middle tooth is adjusted to a suitable size, the clamping block is pressed into the clamping hole, thereby fixing the opposite ends of the two front end adjustment slot blocks.

[0014] When adjusting the distal teeth, the bottom of the first clamping block is slidably connected to the second clamping block. After adjusting to the appropriate size, the clamping block is pressed into the clamping hole to fix the other end of the front adjustment slot block and one end of the rear adjustment slot block. This design can complete the impression of different tooth specifications through adjustment.

[0015] The other end of the sliding block can be deformed through the rectangular groove, so that it contracts when sliding into the card hole, and expands when it is engaged after sliding out of the card hole, so that the arc block engages with the edge of the card hole to achieve the fixing purpose. This method is relatively simple and firmly fixed, which is convenient for operators to operate.
