[0022] Combined with appendix Figure 1-4 The shooting speed detector shown includes a housing, a shooting channel 3, a control board assembly, a firing lens 8, a lithium battery 9, and an LCD screen 10.

[0023] The housing includes a faceplate 1 and an outer shell 2. The faceplate 1 is in the shape of a slot box, and the outer shell 2 is a two-half structure. The two halves of the outer shell 2 are connected by screws. The inner wall of the faceplate 1 is provided with elastic buckles. The faceplate 1 and the outer shell 2 are connected by elastic buckles to form a rectangular housing. The faceplate 1 and the outer shell 2 are provided with corresponding circular mounting grooves. The lower side of the housing is provided with a tripod mounting port.

[0024] The firing channel 3 is a cylindrical structure formed by two semi-circular pieces interlocking. The firing channel 3 is set inside the housing. The two ends of the firing channel 3 are respectively matched with the circular mounting grooves of the faceplate 1 and the outer shell 2. Two sets of arc-shaped grooves 31 are correspondingly provided along the circumference of the outer edge of the firing channel 3.

[0025] The control board assembly includes a first PCB control board 4 and a second PCB control board 6. The first PCB control board 4 and the second PCB control board 6 are respectively disposed in the housings on the left and right sides of the firing channel 3. An infrared emitter 5 is welded on the first PCB control board 4 at the two arc-shaped slots 31 corresponding to the firing channel 3.
