There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft.

[0035] The positioning module 5 includes two circular sleeves 55, and the two circular sleeves 55 are respectively fixedly connected to the two sides of the square plate 14, and corresponding circular guide rods 51 are respectively arranged in the two circular sleeves 55. The lower parts of the two circular guide rods 51 are respectively ring-shaped with corresponding springs 52, and one end of the two springs 52 is respectively fixedly connected to the corresponding circular sleeves 55, and the other ends of the two springs 52 are respectively fixedly connected to the corresponding connecting plates 53, and the two connecting plates 53 are respectively fixedly connected to the circular positioning cylinders 54.
[0036] The clamping module 4 includes a screw rod groove 45 , which is disposed in the middle of the support frame 3 . Two sliders 42 are respectively disposed in the screw rod groove 45 , and the two sliders 42 are respectively fixedly connected to corresponding clamping plates 44 .
[0037] The two inner ends of the screw groove 45 are movably connected to one end of the bidirectional screw 43 respectively.

[0041] The outer surfaces of the two clamping plates 44 are respectively covered with rubber material.
[0042] Working principle: first install the drill bit 63 on the drill bit fixture 62, then place the spline shaft on the support frame 3, so that the spline shaft is between the two clamping plates 45, rotate the turntable 2 41, the turntable 2 41 drives the bidirectional screw 43 to rotate, the bidirectional screw 43 drives the corresponding slider 2 42 to slide, and the two sliders 2 42 drive the corresponding clamping plates 44 to move in the direction close to the spline shaft, so that the two clamping plates 44 clamp the spline shaft respectively, and the outer surfaces of the two clamping plates 44 are respectively coated with rubber material, which can increase the contact area with the spline shaft during the clamping process of the spline shaft, and can prevent the spline shaft from slipping in subsequent operations.
