At this time, the two moving rods 10 passing through the moving groove 8 will be driven away from each other through the trigger component, so that it is convenient to drive the block 7 on the moving rod 10 to move to the end face of the fixing column 4, so that it is convenient to stably install and fix the screw rod 2 on the fixing column 4 through the fixing block 1 and the block 7, so that the temperature sensor can be conveniently fixed on the exhaust pipe and the installation stability of the temperature sensor is guaranteed.

[0022] A probe 3 is fixedly arranged on the screw rod 2 .

[0023] like Figure 4-5 As shown, the trigger assembly includes a fixed rod 9 fixedly provided in the moving groove 8 along the axial direction of the screw rod 2 and located between the two moving rods 10, an elastic member provided on the rod body of the fixed rod 9 and connecting the two moving rods 10, and a trigger member provided on the fixed block 1 and controlling the elastic member to extend.

The second spring 22 is in a compressed state. When the two moving rods 10 are driven away from each other by the trigger assembly, the second spring 22 is extended, thereby facilitating the two moving rods 10 to stably move away from each other, thereby facilitating driving the block 7 fixedly provided on the end of the moving rod 10 to be clamped on the end face of the fixed column 4, thereby ensuring that the screw 2 is stably installed in the threaded hole 5.

[0027] like Figure 3-5 As shown, when the screw rod 2 is inserted into the threaded hole 5 opened in the fixing column 4, the control rod 14 is driven to move upward by the trigger member, so that the end of the control rod 14 leaves the positioning groove 19 opened in the two trigger rods 17. At this time, the two moving rods 10 will drive the moving rods 10 to stably move away from each other under the action of the second spring 22 and the trigger spring 18, and after the screw rod 2 is completely inserted into the threaded hole 5, the block 7 will be ejected onto the end face of the fixing column 4, which is convenient for stably fixing the screw rod 2 in the threaded hole 5, and the temperature sensor can be conveniently fixed on the exhaust pipe, and the installation stability of the temperature sensor is guaranteed.
