[0031] The emitter 310 in the embodiment is used for emitting a laser signal, and the receiver 320 is used for receiving the laser signal, so that the direction and position information of the emitter 310 relative to the receiver 320 can be measured.

[0036] It should be noted that the two shaft holding assemblies 200 are driven to rotate at the same angular velocity through the transmission mechanism 400, avoiding the situation that the two shaft holding assemblies 200 are driven by two hands respectively and are out of synchronization.

[0037] In some embodiments, the transmission mechanism 400 has a connecting column 201 on one side and a corresponding one of the shaft holding assemblies 200, and has a connecting sleeve 401 on the other side.

[0038] The connecting column 201 is arranged along the radial direction of the corresponding shaft holding assembly 200 and is movably inserted into the corresponding connecting sleeve 401.

The rolling bodies 211 are located on the V-shaped surface of the V-shaped block, and each rolling body 211 is arranged around the circumferential side of the shaft head 10.

[0047] In addition, the fastener 220 can be a bolt, a clamp, etc., which is connected with the two shaft-holding blocks 210 respectively, so as to make the two shaft-holding blocks 210 hold or release the shaft head 10, and facilitate disassembly and other operations. The specific type, structure, etc. of the shaft-holding block 210 and the fastener 220 can be determined according to actual needs, and the present embodiment does not make too many limitations.

[0050] It should be noted that the radial direction of the shaft-holding block 210 is the radial direction of the rotation axis of the shaft-holding block 210, and the specific number, specification, etc. of the support rod 212 can be determined according to actual needs, and the present embodiment does not make too many limitations.

[0052] The other side of each bracket 410 is connected with the adjacent transmission assembly 420, and the transmission assembly 420 has the freedom of relative movement and relative deflection of the two brackets 410.

[0053] Specifically, as shown in Figure 1As shown, one side of the bracket 410 is rotatably connected with the corresponding clamping mechanism 100 through a rotating shaft or the like structure, and the rotating axis is consistent with the rotating axis of the nearby shaft holding assembly 200. The bracket 410 is also connected with the shaft holding block 210, so that the shaft holding blocks 210 on both sides rotate at the same angular velocity. The other side of each bracket 410 is connected with the nearby transmission assembly 420, wherein the transmission assembly 420 has the freedom of relative movement and relative deflection of the two brackets 410, so that the two brackets 410 can rotate around the axis of the corresponding shaft holding assembly 200.

[0054] Further, in the embodiment, the transmission assembly 420 includes two universal joints 421 and an extension rod 422. One side of each universal joint 421 is connected with the corresponding bracket 410, and the other side is connected with the end of the nearby extension rod 422, respectively.

[0055] Exemplarily, as shown in the figure, Figure 1 The universal joint 421 can be a cross shaft universal joint or the like, and the extension rod 422 can be composed of a spline rod sleeve and a spline shaft. When the spline shaft is inserted into the spline rod sleeve, it can move axially and can transmit torque. One side of each universal joint 421 is coaxially fixed with the corresponding bracket 410, and the other side is coaxially fixed with the end of the nearby extension rod 422, which is convenient for single-piece machining and subsequent assembly.

[0056] It is worth noting that the extension of the extension rod 422 can also adapt to the measurement of different distances between the two shaft heads 10, and the application range is wider. The specific type, specification, etc. of the universal joint 421 and the extension rod 422 can be determined according to actual needs, and the embodiment does not make too many limitations.

In this way, by rotating the small bevel gear, the three clamping claws 120 can be synchronously driven to move radially inward to be clamped or radially outward to be loosened, and the self-locking performance is stable.

[0060] Of course, the driving assembly 130 can also be replaced by other types of driving components, such as a plurality of telescopic components arranged along the radial direction of the mounting seat 110, each telescopic component is connected to the corresponding clamping claw 120, and each clamping claw 120 can also be driven to move along the radial direction. In this embodiment, the above is not limited.

[0061] Further, in this embodiment, a locking member 411 is arranged between the mounting seat 110 and the support 410 to limit the relative rotation of the mounting seat 110 and the support 410 or to release the limitation.

S101, each clamping mechanism 100 is clamped on the two shaft heads 10 to be connected, and each shaft holding assembly 200 is clamped on the circumferential side of the corresponding shaft head 10.

[0065] Specifically, each clamping mechanism 100 clamps the end position of the shaft head 10, so that the rotation axis of the transmission mechanism 400 on both sides is consistent with the axis of the corresponding shaft head 10. Each shaft holding assembly 200 holds the circumferential side of the corresponding shaft head 10 and can rotate coaxially.

[0066] S102, the transmitter 310 emits a laser signal to the receiver 320, and drives one of the two shaft holding assemblies 200 to rotate by a preset angle.

[0067] Specifically, in the initial position, the transmitter 310 is aligned with the center of the receiver 320, the transmitter 310 emits a laser signal to the receiver 320, and one of the shaft holding assemblies 200 is manually driven to rotate, thereby driving the other shaft holding assembly 200 to rotate at the same angular velocity.
