Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1 and Figure 2, adjustable operation of the present invention intubates propeller, including determining lever 1, dynamic lever 2, the described front end determining lever 1 is fixedly connected with side plate 3, described side plate 3 centrally through bearing, ratchet shaft 4 is installed, between described ratchet shaft 4 and side plate 3, return spring 10 is installed, this return spring 10 can adopt torsion spring as shown in Figure 3, can also adopting helical spring, its effect is can self-return after making ratchet shaft 4 rotate to an angle.The end of ratchet shaft 4 connects dynamic lever 2, is set with the ratchet cover plate 5, is provided with the ratchet mechanism of single direction rotation between the described ratchet cover plate 5 and ratchet shaft 4, can promote the ratchet cover plate 5 synchronous rotary when ratchet shaft 4 turns clockwise time on ratchet shaft 4；When ratchet shaft 4 rotates counterclockwise time, skidding between ratchet shaft 4 and the ratchet cover plate 5, the ratchet cover plate 5 will not rotate with.The concrete form of this ratchet mechanism can have multiple, as shown in Figure 6, the inner periphery at the ratchet cover plate 5 is provided with ratchet, and the excircle of corresponding ratchet shaft 4 is then provided with ratchet, this ratchet is hinged in the groove of ratchet shaft 4 excircle, and utilizes torsion spring to make it have the ability of return.When ratchet shaft 4 turns clockwise, the front end of ratchet is stuck in ratchet, promotes the ratchet cover plate 5 synchronous rotary；When ratchet shaft 4 rotates counterclockwise, ratchet is depressed by the inclined-plane of ratchet, and ratchet shaft 4 can rotate without restriction counterclockwise.It is of course also possible to ratchet is arranged on the inner peripheral surface of the ratchet cover plate 5, and ratchet is arranged on the excircle of ratchet shaft 4.
Determining to be provided with between lever 1 and ratchet shaft 4 tube seat 6, described tube seat 6 is arranged on the tangent line place of the ratchet cover plate 5.As shown in Figure 4, tube seat 6 is provided with notch 61 towards the tube wall of the ratchet cover plate 5, when tube seat 6 near the ratchet cover plate 5 time, the edge of the ratchet cover plate 5 can put in notch 61, pushes down and is arranged in intubating of tube seat 6.The excircle of the described ratchet cover plate 5 is with fluted, in order to the outer surface intubated of better fitting；During use, intubating 9 and be inserted in tube seat 6, the ratchet cover plate 5 is pressed in by the notch on tube seat 6 and intubates on 9, when the ratchet cover plate 5 rotates time, utilizes frictional force promotion to intubate 9 and pushes forward.
One end of described tube seat 6 is installed on determines on lever 1, and the other end of tube seat 6 is connected to by adjusting screw rod 62 to be determined on lever 1.
As shown in Figure 4, Figure 5, described tube seat 6 is installed on the mouth of pipe place of the one end determined on lever 1 with turned-out flanging 63 so that it is is not easy the card dress from determining lever 1 and comes off.The inner side determining lever 1 is provided with the clamp 11 of installing hole, and tube seat 6 is inserted in the installing hole of described clamp 11；The other end of tube seat 6 is fixedly connected with adjusting screw rod 62, described adjusting screw rod 62 runs through to be inserted into be determined on lever 1, adjusting screw rod 62 is provided with fixing nut 64 by screw thread, described fixing nut 64 is provided with annular slot 65, the described upper end determining lever 1 is installed with clip 12, and described clip 12 is connected in the annular slot 65 of fixing nut 64.When rotary fixing screw mother 64, one end of connection adjusting screw rod 62 is conditioned screw rod 62 drive and moves up and down, and can regulate the angle of pitch of tube seat 6 on the one hand, can change again the distance between tube seat 6 and the ratchet cover plate 5 on the other hand, thus regulating the pressure intubated.
As in figure 2 it is shown, be fixedly connected with discoid cover plate 7 on ratchet shaft 4, between the ratchet cover plate 5 and dynamic lever 2, described dynamic lever 2 is fixedly connected on the outside of cover plate 7.The ratchet cover plate 5 is between cover plate 7 and side plate 3, and ratchet mechanism is played a protective role, it is possible to avoids the ratchet cover plate 5 to press from both sides when rotating and causes to seize up into foreign body.
In operation, inserting in tube seat 6 by the front end intubating 9, regulate fixing nut 64 and make the frictional force intubating between 9 and the ratchet cover plate 5 lucky, hold and determine lever 1 and dynamic lever 2, constantly pressing can promote and intubate 9 advances.
