New description: [New technical field] This creation is about a hand puller, especially a hand puller with a double-block improved structure. [Prior Art] As shown in Fig. 11, a conventional hand-held device is used, in which a fixing portion 80 and a pulling portion 81 are combined at one end portion with a shaft portion 82, and a shaft portion 8 2 is provided with a ratchet. 8 3, a blocking piece 8 5 is disposed on the fixing portion 80, and a driving claw 8 6 is disposed on the pulling portion 8 1 , and the blocking piece 8 5 and the driving claw 86 are engaged with the ratchet portion 83. As can be seen from the above structure, the handle has only one baffle 85, and the ratchet 8 3 may have a difference in the ratchet pitch. Therefore, when the puller is tightened, the baffle 8 may be 5 The inability to accurately engage the ratchet 8 3 causes the flap 8 5 to inadvertently disengage from the engagement of the ratchet 8 3 to cause the bundle to be loose. Further, as shown in FIG. 2, it is another conventional hand-held device, and the fixing portion 90 is provided with a second blocking piece 9 1 , and the second blocking piece 9 1 is disposed on the same as the ratchet 9 2 The side fixing portion 90 is engaged with the ratchet 9 2 at the upper and lower sides respectively to achieve the effect of tightening the strap by the puller. However, the retaining walls on both sides of the fixing portion 90 need to increase the height to enable the second blocking piece 9 1 on the same side of the ratchet 9 2, and the structure of the fixing portion 90 is therefore larger than that of the fixed portion of the single blocking piece. In order to make the component cost of the hand puller 3 Ιι'^Μ» η, when the hand puller releases the band, sometimes the belt must be slowly retracted, and this has the hand of the two pieces 9 1 When the puller is slowly retracted, the puller 9 3 must be pulled by the hand to make the second stretcher 9 — the front-back retreat, and sometimes the strap may be excessively disengaged due to improper control. Therefore, how to solve the problem of the above-mentioned conventional hand-held device is the focus of this creation. [New content] One of the purposes of the present invention is to solve the above problems and provide a handcuff device with a double-cylindrical structure, so as to achieve a tightening of the strap, the second flap has a second flap to spray the ratchet. The effect. The second purpose of the present invention is to provide a stroke of the slow disengagement provided by the fixing portion, so that the driving claw of the pulling portion can be displaced in the stroke, and the ratchet can be removed by one tooth and one tooth. For the purpose of the foregoing, the present invention is provided with a shaft portion between a fixing portion and a trigger portion, the shaft portion is respectively provided with a ratchet at both ends, a blocking piece is arranged at the fixing portion, and the blocking portion is further provided. There is a driving claw, the cymbal and the driving claw are respectively coupled to the ratchet of the ratchet, and the fixing portion is respectively provided with a blocking piece on opposite sides of the shaft portion, and the driving claw plate moves the ratchet wheel when rotating The baffle on one side of the ratchet is embedded in the bottom of the ratchet of the ratchet. The other piece on the opposite side of the ratchet is pressed against the ratchet top of the ratchet, and the two-plate is reciprocally reciprocated between the bottom and the top of the ratchet. mobile. The fixing portion has a retaining wall at the pivotal portion of the shaft portion for the end of the driving claw to be at the end of the stroke (4), and the retaining wall is blocked by the wall at the end of the stroke. A positioning slot is defined, and a sliding slot is formed between the slot and the guiding section. And pulling the driving claw to drive the ratchet to rotate in the stroke of the guiding section,

The embodiment provides an improved structure of the hand-held device. The shaft portion 3 is disposed between the fixing portion 1 and the clamping portion 2, and the shaft portion 3 is respectively provided with a ratchet 4' at the two ends. The flap 1 1 ' is further provided with a driving claw 2 1 , and the blocking piece 1 1 and the driving claw 21 are respectively fitted to the ratchet teeth 41 of the ratchet 4 . As shown in FIG. 2, the pulling portion 2 is detachable from the fixing portion 1 by β 5 M384783. The fixing portion 1 is respectively provided on the opposite sides of the shaft portion 3 and is provided with an earning piece 1 1 . When the driving claw 21 pulls the ratchet 4 to rotate, the flap 1 1 on the ratchet wheel 4 side is inserted into the bottom 41 a of the ratchet 41 of the ratchet 4, and the flap 1 1 on the opposite side of the ratchet 4 is pressed against the ratchet The ratchet teeth 4 1 are yii, the 17-piece portion 4 1 b, and the second flap 丄i reciprocates relative to each other between the bottom portion 4 1 a of the ratchet 41 and the portion 4 1b. As shown in the third embodiment, the fixing portion 1 has a guiding portion 12 for abutting the driving claw 21 at the end of the shaft portion 3, and the guiding portion 12 is in the stroke. The end has a side wall of the driving claw 21 abutting against the retaining wall 1 3 '. A positioning groove 14 is defined above the retaining wall 13 3, and there is a sliding between the position groove 14 and the guiding section 1 2 Slot 1 5. As can be seen from the above structure, the driving claw 21 is as shown in Figures 3 to 4, which drives the ratchet 4 to rotate during the stroke of the guiding portion 12, and is pressed against the block when the bottom is pulled. Wall i 3. The triggering portion 2 is provided with two protruding portions 22 corresponding to the two blocking pieces 11 at the position of engaging the shaft portion 3, and the driving claws 2 i are located in the sliding groove i 5 as shown in FIGS. 5 to 6 When the front and rear are displaced, the two projections 2 2 respectively open the corresponding flaps 1 1 , and the ratchets 4 1 of the ratchets 4 are reciprocated and retracted by the stroke of the teeth. As shown in Fig. 7, the driving claw 21 can be completely disengaged from the ratchet teeth when pulled up to the positioning shot 4 and placed in a person. As shown in Figs. 8 to 9, the mosquito unit of the present embodiment has two groups. The perforation i 6, the two sets of perforations 16 are in the two sets of hand-held devices: the parts 1 are connected at the time of docking, and are arranged and assembled by the two sets of the locks i 7 . Therefore, it is not difficult to find the advantages of the present invention by the above description, The fixing portion 1 is provided with a blocking piece 11 on opposite sides of the ratchet wheel. Therefore, even when the pulling portion 2 is pulled, even if the spacing of the ratchet teeth 41 on the ratchet wheel 4 is different, the two blocking pieces 1 1 can be mutually actuated. It can still be engaged with the ratchet 4 to avoid loosening of the strap, and it is not necessary to use the handler as it is necessary to increase the height of the structure on both sides of the fixing portion to accommodate the second flap 1 1, so that the component cost can be relatively More savings. Furthermore, in order to prevent the single-handle puller from being biased or unilaterally tilted due to the unidirectional tightening force, the fixed part 1 of the present invention can pass through the two sets of perforations. The 16 joints are combined with each other, so that the two fixing portions 1 can be driven through the same set of the pulling portions 2 to make the force of the tightening of the cargo more even. Of course, there are still many examples of this creation, only the details change. Referring to FIG. 10, a second embodiment of the present invention, wherein the fixing portion 1A and the trigger portion 2A are engaged with each other in a fixed manner, that is, the fixing portion 1A and the pulling portion 2A are It is not detachable, but the above-mentioned two-piece flap 11A and the effect of slow-rewinding can also be applied to such a fixed type of hand puller. The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives, and it has been in compliance with the provisions of the Patent Law and has filed a patent application.
