An adjusting mechanism 6 is slidably arranged between the two support rods 1. A dislocation mechanism 7 is arranged at the bottom of the adjusting mechanism 6. A blunt head 3 is fixedly arranged at the bottom of the adjusting mechanism 6. The protection mechanism includes a protection component, a rotating shaft 51, a protection gear 52, a first rack 53, a second rack 54, a bottom plate 57 and an L-shaped ejector rod 59. The rotating shaft 51 is rotatably arranged on the assembly plate 4. The protection gear 52 is fixedly arranged at the end of the rotating shaft 51. The first rack 53 is slidably arranged on the assembly plate 4. The second rack 54 is slidably arranged on the assembly plate 4. The L-shaped ejector rod 59 is fixedly arranged at the bottom of the first rack 53. A travel groove is arranged inside the support rod 1. The bottom plate 57 is slidably arranged inside the travel groove. The protection component is arranged inside the travel groove. First, place the part to be tested under the blunt head 3, then unlock the unlocking mechanism. Press down the unlocking mechanism to drive the adjusting mechanism 6, the dislocation mechanism 7 and the blunt head 3 to move downward synchronously to stimulate the patient until the patient gives feedback of feeling and then stop. While pressing down the unlocking mechanism synchronously, drive the protection mechanism 5 to work. The protection mechanism 5 works to drive the one-way mechanism 8 to limit the protection mechanism 5. Then lock the locking mechanism 2. Adjust the required inspection stabbing feeling range and pressure magnitude through the adjusting mechanism 6. After the adjusting mechanism 6 is adjusted, drive the dislocation mechanism 7 to work. Then unlock the locking mechanism 2. Press down the locking mechanism 2 to conduct stabbing feeling inspection on the patient, realizing stabbing feeling inspection with a wide range of multiple pressures, without the need for multiple tests, and can judge the severity of the patient's condition according to the comparison of stabbing feelings of the patient.

[0018] Specifically, the locking mechanism 2 includes a locking plate 21, a plug rod 22, a circular groove 23, a receiving groove 24, a plugging groove 25, a disc 26 and a rotating rod 27.

A number of the T-shaped blocks 61 are slidably located in the corresponding inclined slots 65. When the rotating rod 27 rotates, it drives the screw 66 to rotate. The rotation of the screw 66 drives the conical hollow block 64 to move. The movement of the conical hollow block 64 drives the T-shaped blocks 61 to slide in the inclined slots 65, thereby driving the U-shaped guide rods 63 to move. It realizes the rapid adjustment of the positions of multiple test heads for range stimulation testing. The operation is simple, and the design of the threaded cooperation between the screw 66 and the conical hollow block 64 makes the structure stable.

[0021] Specifically, the dislocation mechanism 7 includes a plurality of limiting frames 71, a plurality of pointed tips 72, a plurality of limiting shafts 73 and a collar 74. The collar 74 is rotatably sleeved on the outer wall of the screw rod 66, and the collar 74 is fixedly connected to the conical hollow block 64. A plurality of the limiting frames 71 are fixedly arranged on the outer wall of the collar 74 in a circular array. A plurality of the limiting shafts 73 are respectively slidably arranged inside the corresponding limiting frames 71. A plurality of the pointed tips 72 are fixedly arranged on the limiting shafts 73. The movement of the U-shaped guide rod 63 drives the corresponding pointed tips 72 and the limiting shafts 73 to move synchronously. While the limiting shafts 73 move, they also move along the limiting frames 71, so that the heights of the corresponding plurality of pointed tips 72 are stepped; realizing multiple stabbing sensation tests at one time, and the severity of the patient's condition can be judged according to the comparison of the corresponding test forces feedback by the patient.

[0022] Specifically, each of the plurality of limiting frames 71 includes a translation section and an inclined section, and the translation sections of the plurality of limiting frames 71 extend in a stepped manner.

[0023] Specifically, each of the two one-way mechanisms 8 includes a plurality of triangular grooves 81, a resisting spring 82 and two wedge-shaped blocks 83. The two wedge-shaped blocks 83 are slidably arranged inside the bottom plate 57. The two ends of the resisting spring 82 are respectively fixedly arranged on the side walls of the two wedge-shaped blocks 83. A plurality of the triangular grooves 81 are arranged on the inner side wall of the receiving groove 24. The upward movement of the bottom plate 57 drives the two wedge-shaped blocks 83 to compress the resisting spring 82 until the wedge-shaped blocks 83 are clamped and limited by the resisting spring 82 when they move to the corresponding triangular grooves 81; realizing automatic limiting after adjusting the test stroke through the bluntness test, which is convenient for subsequent stabbing sensation tests.

[0024] Working principle: First, place the part to be tested under the blunt head 3. Then, by pulling out the insertion rod 22, the vertical limit is released. Press down the rotating rod 27 to drive the overall downward movement of the top plate, the fixed ring 62, and the blunt head 3 to stimulate the patient until the patient gives feedback of feeling, and then stop. Synchronously, when the top plate moves downward, it drives the second rack 54 to move downward. The downward movement of the second rack 54 drives the protection gear 52 to rotate. The rotation of the protection gear 52 drives the first rack 53 to move upward. The upward movement of the first rack 53 drives the L-shaped ejector rod 59 to move upward. The upward movement of the L-shaped ejector rod 59 abuts against the bottom plate 57 to move upward. The upward movement of the bottom plate 57 drives the multi-joint telescopic rod 58 to be stretched. The upward movement of the bottom plate 57 drives the two wedge-shaped blocks 83 to compress and abut against the spring 82 until the wedge-shaped block 83 is engaged and limited by the restoring force of the abutting spring 82 when it moves to the corresponding triangular groove 81. Then, insert the insertion rod 22 into the insertion slot 25. Rotate the rotating rod 27 to drive the screw rod 66 to rotate. The rotation of the screw rod 66 drives the tapered hollow block 64 to move. The movement of the tapered hollow block 64 drives the T-shaped block 61 to slide in the inclined slot 65, thereby driving the U-shaped guide rod 63 to move. The movement of the U-shaped guide rod 63 drives the corresponding pointed heads 72 and the limit shafts 73 to move synchronously. While the limit shaft 73 moves, it moves along the limit frame 71, so that the heights of the corresponding multiple pointed heads 72 are stepped. Then, pull out the insertion rod 22, and press down the locking mechanism 2 to check the stabbing sensation of the patient.
