Drive sleeve described in the utility model is tubulose, and its endoporus and driving shaft form matched in clearance.

Retainer described in the utility model is tubular, its endoporus is comprised of macropore and aperture, top is macropore, bottom is aperture, drive sleeve is arranged in macropore, macropore and drive sleeve form matched in clearance, and aperture and driving shaft form matched in clearance, and macropore and aperture junction are described ratchet-like ring-shaped step.

The tooth top of the ratchet of the ratchet-like ring-shaped step of retainer described in the utility model is greater than the height of drive sleeve to upper surface distance.

Spiral convex rib quantity described in the utility model equates with the spiral grooves quantity of driving shaft.

Driving shaft described in the utility model is plastic material.

Compared with prior art, tool has the following advantages and effect the utility model: key components and parts production process is less, and manufacture craft is simpler, and production efficiency is higher.

The specific embodiment

Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail.

Referring to Fig. 1～Fig. 9, the utility model embodiment comprises handgrip 1, holder 2, driving shaft 3, transmission flap 4, drive sleeve 5, retainer 6, stop collar 7, lower pipe 8 and upper pipe 9.

Handgrip 1 is fixedly connected on outside the upper end of pipe 9, and holder 2 is fixedly connected in pipe 9 upper ends.

Driving shaft 3 upper end pin joints are fixed on holder 2, and driving shaft 3 upper ends are fixed in upper pipe 9 by holder 2.Driving shaft 3 is a cylinder, and its outer surface is provided with several spiral grooves 31.Driving shaft 3 is plastic cement extruded profile, and production efficiency is higher.Driving shaft 3 is plastic material.

Drive sleeve 5 is sleeved on outside driving shaft 3, and is positioned at retainer 6.Drive sleeve 5 is tubulose, and its endoporus and driving shaft 3 form matched in clearance, and endoporus is provided with several spiral convex ribs 51, and spiral convex rib 51 quantity equate with spiral grooves 31 quantity of driving shaft 3,31 one-tenth matched in clearance of spiral convex rib 52 and spiral grooves.Drive sleeve 5 lower ends are provided with ratchet-like ring surface 52.

Retainer 6 is sleeved on outside driving shaft 3 and drive sleeve 5.Retainer 6 is tubular, and its endoporus is comprised of macropore 61 and aperture 62, and top is macropore 61, and bottom is aperture 62.Drive sleeve 5 is arranged in macropore 61, macropore 61 forms matched in clearance with drive sleeve 5, aperture 62 forms matched in clearance with driving shaft 3, and macropore 61 and aperture 62 junctions are ratchet-like ring-shaped step 63, and its ratchet-like ring-shaped step 63 can be mutually meshing with drive sleeve 5 lower end ratchet-like ring surfaces 52.The tooth top of the ratchet of the ratchet-like ring-shaped step of retainer 6 is greater than the height of drive sleeve 5 to upper surface distance, make drive sleeve 5 can be arranged in macropore 61 completely.Retainer 6 is fixedly connected in the upper end of lower pipe 8.

Transmission flap 4 is screwed the top that is connected to retainer 6, and drive sleeve 5 is between retainer 6 and transmission flap 4.6 pairs of drive sleeve 5 of transmission flap 4 and retainer are spacing up and down, and drive sleeve 5 can not dropped out from macropore 61.

Stop collar 7 pin joints are fixed on the lower end of driving shaft 3, and stop collar 7 is positioned at retainer 6 and drive sleeve 5 belows.7 pairs of driving shafts 3 of stop collar are spacing, and driving shaft 3 can not departed from from retainer 6 and drive sleeve 5.

During use, under press pipe 9, by the interaction of spiral grooves 31 and spiral convex rib 51, make drive sleeve 5 descending in the interior rotation of retainer 6, ratchet-like ring-shaped step 63 is mutually meshing with ratchet-like ring surface 52, drive sleeve 5 and retainer 6 are fixed in direction of rotation.Driving shaft 3 makes drive sleeve 5 still have and rotatablely move, and drive sleeve 5 starts to promote retainer 6 and drives lower pipe 8 by the direction rotation of setting.
