[0020] To describe in detail the technical content, the achieved objectives and the effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 2 As shown, a stopwatch clamp of the present utility model includes a base 1 and a clamping assembly 2; a first chute 11 is provided on the top surface of the base 1,

[0022] The clamping assembly 2 includes sliders 21 arranged oppositely, the sliders 21 are slidably arranged on the first chute 11, an arc opening is provided on one end surface of the slider 21 facing the other slider 21, a top block 211 is arranged in the arc opening, and the top block 211 can slide along the radian direction of the arc opening.

[0023] Working principle: Since the first chute 11 is provided on the base 1, the slider 21 of the clamping assembly 2 can abut the top block 211 against both sides of the stopwatch according to the outer dimension of the stopwatch; at the same time, since the top block 211 can slide within the arc opening of the slider 21, the top block 211 can move correspondingly according to the outer contour of the stopwatch, so that the abutting surface of the top block 211 can better conform to the outer contour of the stopwatch, thereby effectively fixing the stopwatch.

[0024] Please refer to Figure 2 As shown, further, a second chute 3 extending along the radian direction of its own arc surface is provided on the arc surface of the arc opening, and a convex block 4 that is snapped into the second chute 3 and slides therein is provided on the top block 211.

[0025] As can be seen from the above description, the top block 211 slides along the radian direction of the arc opening by the sliding of the convex block 4 in the second chute 3.

[0026] Please refer to Figure 2 As shown, further, at least two arc openings are provided at the same height on the end face of the slider 21 facing the other slider 21. Among them, in principle, the more arc openings are provided, that is, the more the number of top blocks 211, the better the clamping assembly can fit the outer contour of the stopwatch. Considering the production cost, it is preferred to provide two arc openings on the slider 21, that is, two top blocks 211 are slidably arranged on the slider 21.

[0027] Please refer to Figure 1 As shown, further, the clamping assembly 2 further includes a positioning post 22; a plurality of auxiliary positioning holes 12 are provided on the top surface of the base 1, and the auxiliary positioning holes 12 are at least located on one side of the length direction of the first chute 11, and one end of the positioning post 22 can be inserted into the auxiliary positioning holes 12. Preferably, an external thread is provided at the end of the positioning post 22, and the auxiliary positioning hole 12 is a threaded hole, and the positioning post 22 is fixed to the base 1 by means of a threaded connection.

[0028] As can be seen from the above description, after the top block 211 clamps the stopwatch, a certain number of positioning posts 22 can be appropriately inserted into the auxiliary positioning holes 12 according to the shape of the outer contour of the stopwatch, and the column body of the positioning post 22 abuts against the outer contour of the stopwatch, so as to further strengthen the stability of the stopwatch on the base 1.

[0029] Please refer to Figure 3 As shown, a stopwatch calibrator of the present utility model includes a calibrator main body 5 and a stopwatch clamp, and an electric control striker 13 is provided on the base 1, and the electric control striker 13 is electrically connected to the calibrator main body 5.
