At the same time, with the addition of a binding rope, the cable can be rolled up and bound after use of the hyperbolic beam tension pressure sensor, thereby avoiding cable entanglement.

[0034] The single-point connector 4 is arranged at the middle of the front end of the substrate 1. Sensor elements 5 are arranged around the front end of the substrate 1.

[0035] A shock absorbing spring 6 is arranged on both sides of the top of the base 1, and the other end of the shock absorbing spring 6 is connected to an additional shell 7. The base 1 and the additional shell 7 are also connected by a telescopic long rod 8;

[0036] The upper beam 2 and the lower beam 3 are distributed in a ring shape with respect to the inside of the base 1, and the center point of the base 1 is consistent with the center point of the single-point joint 4, and the sensor element 5 is annularly embedded in the front end of the base 1, and the single-point joint 4 is a spherical structure. Through the design of the single-point joint 4, the double-layer beam curved beam structure can be used for single-output and dual-output dual-control signal sensors;

[0037] The shock absorbing springs 6 are symmetrically distributed about the vertical center axis of the base 1, and the base 1, the shock absorbing springs 6 and the additional shell 7 are elastically connected. The top and bottom ends of the base 1 are connected to the additional shell 7 through the shock absorbing springs 6 and the telescopic long rods 8, so that when the base 1 touches or collides with a hard object, the impact force can be buffered and released by the structure, thereby protecting and maintaining the original state of the internal structure of the base 1, and avoiding the displacement between parts to affect the normal use of the equipment;

[0038] The base body 1 also has:

[0039] A traction belt 9 is connected to the middle of the right side of the base 1. A protective cover 10 is provided at the other end of the traction belt 9. Sealing rods 11 are fixed around the front end of the protective cover 10. A filling layer 12 is connected to the front end of the protective cover 10.

[0040] The heat sink 13 is closely attached to the rear end surface of the protective cover 10. The rear end of the protective cover 10 is surrounded by heat-conducting bumps 14.

[0041] The base 1, the traction belt 9 and the protective cover 10 are fixedly connected, and the inner diameter of the protective cover 10 is consistent with the outer diameter of the base 1;

[0042] The sealing rods 11 are distributed in a ring shape at the front end of the protective cover 10, and the number of the sealing rods 11 and the sensor element 5 are consistent.

When the user uses it, the side of the protective cover 10 with the heat-conducting protrusion 14 corresponds to the rear surface of the base 1, and the heat-conducting protrusion 14 is used to conduct the heat accumulated in the base 1 to the heat sink 13, and the heat sink 13 is used to increase the speed of heat dissipation. Conversely, after use, the side of the protective cover 10 with the sealing rod 11 is covered On the front end surface of the substrate 1, the positions of the sealing rod 11 and the sensor element 5 can correspond one to one, thereby effectively preventing dirt from invading the interior of the sensor element 5. At the same time, the filling layer 12 is filled on the front end surface of the substrate 1 to enhance the fit between the two and reduce the possibility of decreased sensitivity. Then, the binding rope 17 is used to roll up and bind the cable 15, so as to prevent the cable 15 from being too long and entangled, affecting the next use. The outer side of the substrate 1 is connected with the shock-absorbing spring 6, the telescopic long rod 8 and the additional shell 7 in sequence, so that when the substrate 1 touches or collides with a hard object, the impact force can be buffered and released by the structure, so as to protect and maintain the original state of the internal structure of the substrate 1, and avoid the displacement between parts affecting the normal use of the equipment.
