Socket part, spiro union portion are screwed onto in the screw hole for the locating rod having on the wall surface of limiting plate, solid on the relative wall of two limiting plates
Flexible fixed, oscillating rod is between two limiting plates.
Self-lubricating set is inserted in the swing connector sleeve, the lateral wall of self-lubricating set is fixed on the inside for swinging connector sleeve
On wall, for articulated shaft sleeve in self-lubricating set, the both ends of the surface of self-lubricating set are pressed against end face and the limit of corresponding transverse connecting shaft
On the end face of position lid.
One end top surface of the foot pedal has ladder hole, and the big end diameter of upper end diameter of ladder hole is small, swings
Simultaneously at the upper end of ladder hole, the bar portion of fixing bolt passes through the lower end of ladder hole and is screwed onto the lower end sleeve of bar for holding
In the lower bolt apertures that the bottom end of oscillating rod has, the head of fixing bolt is pressed against on the bottom surface of foot pedal.
The present invention protrusion effect be:Compared with prior art, its oscillating rod amplitude of fluctuation can be adjusted, and prevent
Amplitude of fluctuation is excessive, and effect is good, efficient.

Fig. 1 is the structural schematic diagram of the present invention;
Fig. 2 is the partial enlarged view of the present invention;
Fig. 3 is the partial structural diagram between the center column and cross connecting plate of the present invention;
Fig. 4 is the partial structural diagram between the upper limit set of the present invention and hand-held part.
Specific implementation mode:
Embodiment is shown in as shown in Figures 1 to 4, a kind of left and right side-sway device, including center column 10, the center column 10
Bottom surface is fixed with bottom plate 11, and bottom plate 11 fixes on the ground, and the top of center column 10 has the column that is spirally connected upwardly extended
12, the top for the column 12 that is spirally connected is bolted with upper limit set 13, and transverse connecting shaft 14 is fixed on the left and right sides wall of upper limit set 13,
The end of transverse connecting shaft 14 is fixed with articulated shaft 15, and the end of articulated shaft 15 is bolted with limited cover 16, swings connector sleeve 20 and cuts with scissors
It is connected in articulated shaft 15 and between end face and the end face of limited cover 16 in transverse connecting shaft 14;
The bottom end for swinging connector sleeve 20 is fixed with oscillating rod 21, and the lower end of oscillating rod 21 is fixed with foot pedal 22;
The upper portion side wall of the front and rear sides of the upper limit set 13 is fixed with interconnecting piece 131, and cross is fixed on interconnecting piece 131
To connecting rod 132, the both ends of transverse connecting rod 132 are fixed with hand-held part 133, former and later two hand-held parts 133 of the same side with it is same
The foot pedal 22 of side is corresponding, and foot pedal 22 is between two hand-held parts 133 of the same side;
The left and right sides wall of the center column 10 is fixedly arranged in the middle of cross connecting plate 17, the both ends of cross connecting plate 17
With welded plate, there is jack 171 on welded plate, bulb plunger 172 is bolted on the madial wall of jack 171, shank 173 is inserted
It is sleeved in jack 171, the steel ball of bulb plunger 172 stretches out the madial wall of jack 171 and is nested on the lateral wall of shank 173
In the shrinkage pool 174 having, the end of shank 173 is spiro union portion, and spiro union portion is screwed onto determining of having on the wall surface of limiting plate 175
In the screw hole of position bar 176, elastic piece 177 is fixed on the relative wall of two limiting plates 175, oscillating rod 21 is in two limits
Between plate 175.
Further, self-lubricating set is inserted in the swing connector sleeve 20, the lateral wall of self-lubricating set is fixed on pendulum
On the madial wall of dynamic connector sleeve 20, for 15 sleeve of articulated shaft in self-lubricating set, the both ends of the surface of self-lubricating set are pressed against corresponding cross
To on the end face of connecting shaft 14 and the end face of limited cover 16.
Further, one end top surface of the foot pedal 22 has ladder hole 221, the upper end of ladder hole 221 straight
The big end diameter of diameter is small, and simultaneously holding is at the upper end of ladder hole 221 for the lower end sleeve of oscillating rod 21, the bar of fixing bolt 222
Portion passes through the lower end of ladder hole 221 and is screwed onto in the lower bolt apertures that the bottom end of oscillating rod 21 has, the head of fixing bolt 222
Portion is pressed against on the bottom surface of foot pedal 22.
Operation principle:By adjusting upper limit set 13, foot pedal 22 can be adjusted the distance between from the ground, and by turning
Dynamic limiting plate 175, can adjust the distance before two limiting plates 175, and then, people stands in 22 enterprising swing of foot pedal, pendulum
Lever 21, which is pressed against on elastic piece 177, realizes limit, and restraining position is adjustable, safe to ensure that its swing effect is good.
Finally, embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, related technical field
Those of ordinary skill can also make a variety of changes and modification without departing from the spirit and scope of the present invention, therefore
All equivalent technical solutions also belong to scope of the invention, and scope of patent protection of the invention should be defined by the claims.
