[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, the engine sensor includes an engine body 1, on which a sensor 2 for detection is arranged, and a slot for installing the sensor 2 is provided on the engine body 1. The sensor 2 is composed of a sensor head 3, a control element and a mounting shell 4. One end of the sensor head 3 extends into the engine body 1, and the other end of the sensor head 3 is connected to the mounting shell 4. A fixing seat 5 is fixedly arranged on the engine body 1 at a position relative to the slot, and a plurality of positioning columns 6 for cooperating with the mounting shell 4 are arranged on the fixing seat 5. A positioning ring 7 cooperating with the positioning columns 6 is arranged on the mounting shell 4, and a plurality of positioning openings for the positioning columns 6 to pass through are opened on the positioning ring 7. A positioning assembly 8 for positioning the positioning ring 7 is provided on the positioning column 6, and the positioning assembly 8 is composed of a positioning rod 9 and a reset spring 10. The sensor 2 can be detachably fixed to the slot through the action of the positioning assembly 8.

[0015] To further elaborate, a mounting groove 11 for installing the positioning assembly 8 is provided on the positioning column 6, one end of the positioning rod 9 is arranged in the mounting groove 11 and is connected to a return spring 10, so that the positioning rod 9 can slide in the mounting groove 11, and the other end of the positioning rod 9 extends out of the mounting groove 11 and is used to fix the positioning ring 7.

[0016] To explain in further detail, when the sensor 2 is installed, pressure is applied to the positioning rod 9 to shrink the positioning rod 9 into the installation groove 11, and the reset spring 10 is in a compressed state. The fixing seat 5 is first matched with the positioning column 6 to install the fixing seat 5, and then the positioning ring 7 on the sensor 2 is also matched with the positioning column 6. When the installation is completed, the reset spring 10 rebounds to position the sensor 2. When the sensor 2 is disassembled, pressure is applied to the positioning rod 9 to shrink the positioning rod 9 into the installation groove 11, and the sensor 2 and the connecting seat 12 are disassembled, so that the operator can repair or replace the sensor 2.

[0017] In further detail, a connecting seat 12 is fixedly arranged between the fixing seat 5 and the positioning ring 7, and a through hole is provided on the connecting seat 12 for the positioning column 6 to pass through. A groove is provided on the fixing seat 5 for the connecting seat 12 to be installed. When positioning the sensor 2, the connecting seat 12 is first matched with the groove of the fixing seat 5, the positioning column 6 is passed through the through hole of the connecting seat 12, and then the sensor 2 is installed and positioned. The presence of the fixing seat 5 and the positioning assembly 8 enhances the stability of the installation of the sensor 2.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
