Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 5 and give, including the solid fixed cylinder 1 of left and right directions, solid fixed cylinder 1 right-hand member is equipped with isosceles trapezoid's fixed frame 2, sliding connection has the driving plate 3 of left and right directions in the solid fixed cylinder 1, 3 left end fixedly connected with racks 4 of driving plate, the downside is equipped with and meshes and rotatable half-gear 5 with racks 4 in the solid fixed cylinder 1, 3 right-hand members of driving plate are equipped with push pedal 6, 6 right-hand members of push pedal are equipped with a plurality of arm-tie 7 along fore-and-aft direction equipartition and upper and lower direction, 7 lower extremes of arm-tie are equipped with a plurality of thin hooks 8 that are located its left side and follow the fore-and-aft direction equipartition.
In order to make the half gear 5 rotatable, the front end of the half gear 5 is coaxially provided with a swing plate 9 in the left-right direction, and the right end of the swing plate 9 is provided with a circular groove.
In order to limit the movement of the transmission plate 3, a plurality of limiting grooves 10 are uniformly distributed along the left-right direction on the transmission plate 3, and a limiting rod 11 capable of being inserted into the limiting grooves 10 is connected to the fixed cylinder 1 in a sliding manner.
In order to facilitate the resetting of the limiting rod 11, the limiting rod 11 is connected with the fixed cylinder 1 through a first tension spring.
In order to facilitate the reset of the rack 4, a second tension spring is arranged between the fixed cylinder 1 and the rack 4.
In order to facilitate better use, the lower end of the fixed cylinder 1 is provided with a handle 12.
The utility model discloses when using, hold handle 12, upwards stimulate gag lever post 11, first extension spring is stretched this moment, remove the spacing to drive plate 3, rotate swing plate 9, swing plate 9 drives half gear 5 and rotates, half gear 5 drives rack 4 and moves to the right, the second extension spring is stretched this moment, rack 4 drives push pedal 6 through drive plate 3 and moves to the right, push pedal 6 drives thin hook 8 through arm-tie 7 and moves to the right, continue to rotate swing plate 9, arm-tie 7 continues to drive thin hook 8 and moves to the right, move out fixed frame 2 right at arm-tie 7 drives thin hook 8;
the swinging plate 9 continues to swing, when the pulling plate 7 moves rightwards to a proper position, the swinging plate 9 stops swinging, the limiting rod 11 is loosened, the limiting rod 11 moves downwards and is inserted into the limiting groove 10 under the action of the first tension spring to limit the movement of the driving plate 3, so that the medical staff can conveniently and safely operate, the pulling plate 7 is prevented from moving to cause injury to a patient, and the medical staff can operate an affected part of the patient;
