[0035] The positioning component 3 includes a positioning plate and positioning columns. On one side of the positioning plate, there is a groove for accommodating the transmission component 2; in the groove, there are positioning columns and several through holes; on the side of the positioning plate away from the groove, there is also a positioning groove whose size matches the reaction module, and the through holes connect the groove and the positioning groove;

[0036] The transmission component 2 includes a driving rod 2.1, four gears one 2.2, nine gears two 2.3, and nine transmission rods 2.4. Among them, the nine transmission rods 2.4 are arranged in a "field" shape evenly, and each transmission rod 2.4 is provided with a gear two 2.3. On the transmission rod 2.4 located at the center, there is a fixed rod. The four gears one 2.2 are arranged in a "field" shape evenly between the nine transmission rods 2.4 and are all meshed with the gear two 2.3 on the transmission rod 2.4 provided with the driving rod 2.1. At least one gear two 2.3 is meshed with at least one gear one 2.2 (as Figure 1 shown); one end of the transmission rod 2.4 is located in the groove, and the other end passes through the through hole and is located in the positioning groove; the bit 4 is arranged at one end of the transmission rod 2.4 located in the positioning groove, and the sum of the length of the transmission rod 2.4 located in the positioning groove and the length of the bit 4 is less than the depth of the positioning groove; in this example, the end of the driving rod 2.1 away from the transmission rod 2.4 is used to connect with an external driving part.
