61 rotation position.The setting of rotating wheel 64 play it is good be in contact with balancing weight 3, during block 61 is promoted, rotation
Contact position can change when turning, and realized using rotating wheel 64 and roll cooperation, avoid interstructural impaired, the guarantee balancing weight 3 that collides with
Quality it is accurate.The setting of torsion spring makes block 61 reset, and mutually stops defined position with bearing 66 by riser 63 when resetting, and ties
Structure is ingenious.
As an improvement embodiment, release cylinder 52 include a push pedal 521, the retrieving position of push pedal 521
The initial position of corresponding balancing weight 3, when foot platform pushes to the initial position of balancing weight 3 in place by propulsion cylinder 51 by pushing away
Plate 521 stops positioning.It is accurate when foot platform is pushed to 3 initial position of balancing weight that the position of push pedal 521 ensure that, raising is matched somebody with somebody
The relative position accuracy placed on it of pouring weight 3, ensure that the data of all tests are unified accurate, error is smaller caused by instrument.
As an improvement embodiment, the activity direction of balancing weight 3 is provided with limiting plate 13 on base 11,
Limiting plate 13 is arranged on the both sides of balancing weight 3, close to the position of limiting plate 13 for releasing cylinder 52 and the retrieving position pair of push pedal 521
Should be concordant.The activity skew that the further specification balancing weight 3 of limiting plate 13 and foot platform are likely to occur after being pulled is set, really
Guarantor's balancing weight 3 and foot platform position when resetting are accurate, and foot platform can accurately be released by releasing cylinder 52.
It the above is only preferred embodiment of the present utility model, the scope of protection of the utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should be pointed out that pair
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
