In addition, as shown in Figure 9, second hyoplastron 16 and second spring 17 are set in the inner chamber of support 6, this support 6 also is provided with second retention device and the 4th retention device.Specifically, second hyoplastron 16 is placed on the support chassis 6-1 in the support 6; The two side of support 6 in the bottom of itself and second hyoplastron 16 promptly the corresponding position of the second hyoplastron second portion 16-2 respectively have a support cinclides 6-2, this moment, second hyoplastron 16 can be the T font, promptly the second hyoplastron second portion 16-2 is wideer than second 16-1 of hyoplastron first portion, so that the two ends of the second hyoplastron second portion 16-2 can be stuck in the support cinclides 6-2, the left side of the second hyoplastron second portion 16-2 is abutted against on the inwall 6-2-1 of support cinclides 6-2, and the inwall 6-2-1 of support cinclides 6-2 then constitutes second retention device of the present utility model.Certainly, if the two side of support 6 does not have above-mentioned support cinclides 6-2, then also can realize its barrier effect by on the relevant position of the two side of support 6, being processed with projection (not illustrating in the drawings) respectively to second hyoplastron 16, this projection of this moment is the another kind of embodiment of second retention device, and second hyoplastron 16 of this moment is correspondingly change then.Moreover, the right side of the second hyoplastron second portion 16-2 also nestles up second spring 17.This second spring 17 is placed on the 6-1 of support chassis, and the left end of second spring 17 nestles up cradle wall 6-3 again.
The driving and the locking function of the utility model drive unit are realized in the following manner: chock 18 is raised make it unlikelyly withstand first hyoplastron 14 earlier, so that first hyoplastron 14 can retreat and be reciprocating; Then driving handle 11 is pressed down and make first 14-1 of hyoplastron first portion begin to promote ratchet 13 to clockwise rotate certain one stroke by initial position, and the top that also promotes second hyoplastron 16 simultaneously that clockwise rotates of ratchet 13 is that second 16-1 of hyoplastron first portion is flapped toward the right side, this moment, the bottom of second hyoplastron was that the second hyoplastron second portion 16-2 is owing to be between the inwall 6-2-1 of second spring 17 and support cinclides 6-2, therefore whole second hyoplastron 17 still can remain on original position substantially, then apply an active force that makes progress to driving handle 11 again, rely on the stopping function of 17 pairs of ratchets 13 of second hyoplastron this moment, first hyoplastron 14 can retreat and start first 14-1 of hyoplastron first portion along the slippage that makes progress of described hook tooth, so as for its for the second time driving pawl 13 rotate and prepare.As mentioned above, the active force that should make progress is from the elastic force of extension spring 10 in the present embodiment, if do not use this extension spring 10 certainly, above-mentioned active force also can directly be applied from the external world by the operator, as will lifting on the driving handle 11 with hand.Afterwards, according to the method described above driving handle 11 is pressed down again and make first 14-1 of hyoplastron first portion promote ratchet 13 once more to clockwise rotate certain one stroke and driven the second time of ratchet 13 realizing by initial position, so multi-pass operation, make ratchet 13 be achieved unidirectional, lasting clockwise rotating, the lasting rotation of ratchet 13 drives the synchronous rotation of ratchet shaft 9, each stay cord of constantly reeling thus, stay cord drives connected claw, the chuck of claw is drawn close to the central authorities of cylinder barrel 2, thereby gripped object is clamped.In case gripped object is clamped, chock 18 downward modulations can be made it to withstand the return motion of first hyoplastron 14 with the restriction latter, thereby realize the locking function to ratchet 13, make binding clasp be in stable clamped condition.And the prerequisite of unclamping gripped object is to guarantee that ratchet 13 can freely turn round fully, promptly will avoid first hyoplastron 14 and second hyoplastron 16 to hinder the rotation of ratchet 13, and this mainly is to rely on cooperatively interacting of each relevant portion of drive unit to realize.Specific as follows: as at first chock 18 to be raised and make it unlikely first hyoplastron 14 that withstands; Then driving handle 11 is applied an active force that makes progress and makes driving handle 11 enough strokes that moves upward, in driving handle 11 moves upward process, first hyoplastron 14 successively be subjected to ratchet 13 and support as shown in Figure 36 outer rim 6-4 barrier effect and retreat.Especially, owing to be subjected to the thrust backward of the outer rim 6-4 of support 6, this first hyoplastron 14 14-1 of first portion just may retreat into the unlikely position of freely rotating that stops ratchet 13, thereby provide possibility for freely turning round of ratchet 13.The outer rim 6-4 that it is pointed out that above-mentioned support 6 promptly is wherein a kind of specific implementation of the 4th retention device of the present utility model, and above-mentioned the 4th retention device also can be realized by on the madial wall of the left and right sides of support 6 flange being set respectively.Certainly, above-mentioned the 4th retention device yet can be by other suitable form of expression.Because the front end of driving handle 11 has a curved surface 11-3-2, make that lifting driving handle 11 makes it when axle rotates counterclockwise, its preceding end curved surface 11-3-2 can push second 16-1 of hyoplastron first portion and make its freely turning round of offset straight to the second hyoplastron first portion unlikely obstruction ratchet 13 of 16-1 to the right;
