Description
Technical field
The utility model belongs to hand-operated tools technical field, especially with a kind of lug wrench.
Background technology
The lug wrench for being currently used for switching exterior angle screw generally uses ratchet mechanism, lug wrench when in use, only to need
Swing back and forth the handle of spanner, so that it may turn nut and rotate in one direction.However existing lug wrench is needing to adjust spiral shell
It could be used after bolt, using being more troublesome.
Utility model content
For above-mentioned background technology there are the problem of, the utility model is intended to provide a kind of lug wrench easy to use.
For this purpose, the utility model uses following technical scheme：A kind of lug wrench, including handle and sleeve, characterized in that
Through-hole is arranged in the head of the handle, and the sleeve is set in through-hole, and the endoporus of sleeve is as switching exterior angle screw
Spanner mouth, the hole wall at the both ends of the through-hole are equipped with the circular groove of indent, clamp spring, the inner end of clamp spring are arranged in circular groove
Face contacts on the step surface of both ends formation of the sleeve, is axially limited in the sleeve in through-hole by clamp spring；
The hole wall of the through-hole of the sleeve is equipped with the block of the evagination of multiple even circumferentials distribution, two neighboring block
Between form roller accommodating chamber, be both provided with cylindrical roller in roller accommodating chamber, roller accommodating chamber is in the sleeve axial direction
Projection it is wedge shaped, the thickness of roller accommodating chamber small end is less than the diameter of the cylindrical roller, the thickness of roller accommodating chamber big end
Not less than the diameter of cylindrical roller.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The block there are six being set on the sleeve.
The utility model can reach following advantageous effect：Multiple phases are arranged by the peripheral surface in sleeve in the utility model
Mutual independent roller accommodating chamber, since roller accommodating chamber is wedge shaped in the projection of sleeve axial direction, the past wedge-shaped big end side of sleeve
To when switching, sleeve pushes cylindrical roller rotation, and by sleeve toward when wedge-shaped small extreme direction switching, cylindrical roller is by roller accommodating chamber
It blocks, to reach the function of lug wrench, the utility model is easy to use, without adjusting.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the internal structure schematic diagram that the sleeve of this utility model is installed.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As Figure 1-Figure 2, the utility model includes handle 1 and sleeve 2, and through-hole is arranged in the head of handle 1, and sleeve 2 is set
It is placed in through-hole, the spanner mouth of the endoporus 6 of sleeve 2 as switching exterior angle screw, the hole wall at the both ends of through-hole is equipped with the circle of indent
Connected in star, circular groove is interior to be arranged clamp spring 7, and the inner face of clamp spring contacts on the step surface of both ends formation of sleeve, passes through card
Spring 7 is by 2 axial limiting of the sleeve in through-hole；The evagination of even circumferential distribution there are six being set on the hole wall of the through-hole of sleeve 2
Block 3, form roller accommodating chamber 4 between two neighboring block, cylindrical roller 5 be both provided in roller accommodating chamber 4, roller holds
Chamber 4 of receiving is wedge shaped in the projection of 2 axial direction of the sleeve, and the thickness of roller accommodating chamber small end is less than the cylindrical roller 5
Diameter, the thickness of 4 big end of roller accommodating chamber are not less than the diameter of cylindrical roller 5.
