[0014] The shifting machine chest rest connecting mechanism will be further described in combination with the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0015] Figure 1 Fig. 1 is a schematic view of the shifting machine chest rest connecting mechanism;

[0016] Figure 2 Fig. 2 is a top view of the shifting machine chest rest connecting mechanism;

[0017] Figure 3 Fig. 3 is another angle view of the shifting machine chest rest connecting mechanism;

[0018] Figure 4 Fig. 4 is another angle view of the shifting machine chest rest connecting mechanism.

[0019] In the figure, 1 is a chest rest, 2 is a chest rest motor, 3 is a fixed plate, 4 is a top plate, 5 is a side plate, 6 is a lower connecting rod, 7 is an upper connecting rod, 8 is a bottom plate, and 9 is a connecting rod. DETAILED DESCRIPTION

[0020] As Figures 1-4As shown, a shift machine chest rest connecting mechanism, including a chest rest 1, the upper back of the chest rest 1 is hinged to one end of a chest rest motor 2, the other end of the telescopic rod of the chest rest motor 2 is hinged to a fixed sheet 3, the fixed sheet 3 is fixedly connected to the top of a bracket, the lower side of the bracket is hinged to one end of a lower connecting rod 6, the other end of the lower connecting rod 6 is hinged to the lower back of the chest rest 1; the upper side of the bracket is hinged to one end of an upper connecting rod 7, the other end of the upper connecting rod 7 is hinged to the upper back of the chest rest 1.

[0021] The number of the lower connecting rod 6 is two, which are symmetrically arranged left and right, and two lower connecting rods 6 are connected by two connecting rods 9, one of which connects the middle part of the two lower connecting rods 6, and the other connects the front part of the two lower connecting rods 6.

[0022] The number of the upper connecting rod 7 is two, which are symmetrically arranged left and right.

[0023] The top of the bracket is a top plate 4, and the left and right sides of the top plate 4 are connected to a side plate 5 respectively, and the bottom of the two side plates 5 is fixedly connected to a bottom plate 8. The top plate 4, the side plate 5 and the bottom plate 8 form a bracket, which is an upper connecting frame of the shift machine, and the upper connecting frame is connected to the body of the shift machine.

[0024] In operation, the telescopic rod is controlled to extend or retract by the chest rest motor 2, thereby driving the chest rest 1 to rotate upward or downward. When the shift machine is lifted, the shift machine chest rest connecting mechanism drives the human body to move upward or downward, and the two ends of the lower connecting rod 6 and the upper connecting rod 7 rotate adaptively around the hinge points, thereby cooperating with the chest rest to move.
