The clamping head 20223 is provided with a guide groove 20224, which is used for guiding the PIN needle 4 when it is inserted into the clamping head 20223.

[0046] The welding wire 20221 is used to lead out the test signal after wiring. The fixing rod 20222 is a plastic needle rod, which is used to fix the probe, and the diameter and length can be changed according to the needs. The clamping head 20223 can better contact the detection product 3, and the plug part can change the head shape according to the needs, such as the angle of the tapered part. The clamping head 20223 is a double-piece clamp, and the double-piece clamp has a certain elastic metal sheet, which can achieve clamping.

[0047] The fixing block 201 is provided with a fixing hole 2011, and the fixing block 201 is detachably arranged on the mounting housing 1 through the fixing hole 2011 and the bolt.
