The invention aims to provide a track and field starting block to solve the problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a race starter for track and field, includes the main part, the recess that link up around seting up in the main part, and the rear end of recess is provided with the counter weight seat, the outward appearance both sides of main part rear end all are provided with the back seat, and the place ahead of back seat is provided with tramples the ware, all be provided with the spout on the both sides inner wall of recess, the inboard of trampling the ware is provided with the bolt, and the other end of bolt passes the fixed orifices and is connected with the slider, the bottom of main part is provided with the skid resistant course, and both ends are provided with a plurality of ground nails.

Preferably, the trample devices are arranged in two numbers, and the two trample devices are arranged on two sides of the outer surface of the main body in a staggered mode.

Preferably, the sliding groove is fixedly connected to the inner wall of the groove through a screw.

Preferably, both sides of the main body and the sliding grooves are provided with fixing holes. The fixing holes on the two sides of the main body correspond to the fixing holes on the sliding grooves one to one.

Preferably, the sliding block is connected with the sliding groove in a sliding mode.

Preferably, the front surface of the treadle is provided with a non-slip mat.

Compared with the prior art, the invention has the beneficial effects that: the treadle device is connected with the sliding block through the round hole through the bolt, the treadle device is more stable, the treadle device cannot be dislocated, so that the exertion of a sportsman cannot be influenced, the anti-slip layer arranged at the bottom of the main body and the anti-slip pad arranged on the treadle device increase the friction force, the sportsman cannot be influenced by slipping when running, the arrangement of the balance weight seat can play a role in slip prevention, and the arrangement of the serial number mark and the ground nail on the surface of the balance weight seat can ensure that the main body and the ground are firmer and cannot slide.
