[0037] Please refer to Figures 1 to 3 The utility model provides a press type adjusted starting device pedal, including fixed baseplate 1, upright support 2, pedal plate 3, transmission arm 4, adjusting rotary cylinder 5, columnar bolt 6 and the adjustment tooth groove 7 and the adjustment tooth that are adapted, the bottom of pedal plate 3 is hinged on fixed baseplate 1, fixed baseplate 1 still is provided with upright support 2, columnar bolt 6 is provided with tooth segment 8, the accommodating slot 15 that is accommodated tooth segment 8 is seted up in upright support 2, the accommodating slot 15 and the inner wall of adjusting rotary cylinder 5 are all seted up adjustment tooth groove 7, tooth segment 8 is provided with adjustment tooth, adjustment tooth is simultaneously with the adjustment tooth groove 7 in the accommodating slot 15 and the adjustment tooth groove 7 on the inner wall of adjusting rotary cylinder 5 and is in gear, adjusting rotary cylinder 5 is connected with the middle part of pedal plate 3 through transmission arm 4. Further, the adjustment tooth groove 7 and adjustment tooth are all metal material, have good durability. It can be understood that columnar bolt 6 can be located at the left side, right side or left and right sides of upright support 2, the columnar bolt 6 shown in the drawing is located at the right side of upright support 2 only as an illustration, and the same columnar bolt 6 and the corresponding matching structure can be located at the left side or left and right sides of upright support 2, that is, the left side, right side or left and right sides of upright support 2 can be adjusted by pressing.

[0038] The working principle of the press-type adjustment starting block in this embodiment is as follows: when the angle is fixed, the adjustment tooth is in close engagement with the adjustment tooth groove 7 in the accommodation groove 15 and the adjustment tooth groove 7 on the inner wall of the adjustment rotating drum 5, forming a stable locking state, and when the angle of the starting block plate 3 needs to be adjusted, the user can exit the locking state of the adjustment tooth by a simple pressing action, and then operate the adjustment rotating drum 5, so that the adjustment rotating drum 5 is connected with the starting block plate 3 through the transmission arm 4, so that the starting block plate 3 rotates around the bottom hinge point, and the angle is adjusted. In this process, the tooth segment 8 on the columnar plug 6 moves with the rotation of the adjustment rotating drum 5, and at the same time the columnar plug 6 rotates on the upright support 2, and the double engagement mechanism ensures the stability and accuracy during adjustment.

[0039] Please refer to Figure 2 and Figure 4 , the tooth segment 8 on the columnar plug 6 is a straight line segment or an inclined segment. When the tooth segment on the columnar plug is designed as a straight line segment, its main feature is simple and stable. The straight line segment tooth segment 8 is easy to manufacture and process, and the cost is relatively low.
