A kind of adjustable type quick change plum blossom ratchet torque spanner sectional view that Fig. 2 provides for the utility model.
Detailed description of the invention
With reference to accompanying drawing.A kind of adjustable type quick change plum blossom ratchet torque spanner, comprise plum blossom ratchet sleeve 1, handle 5, the swingable parts 3 being used for quick change and connecting plum blossom ratchet sleeve are connected in handle 5, there is rectangle side's tenon 10 described plum blossom ratchet sleeve 1 rear end, the wall of described swingable parts 3 rectangular opening 30 is provided with circular hole, described side's tenon is provided with installing hole, the steel ball 41 being provided with spring 42 in installing hole and being supported by spring 42, forms quick change be connected when square tenon inserts rectangular opening by steel ball 41 with the cooperation of described circular hole.
By the connected mode of rectangle side's tenon 10, located the installation direction of plum blossom ratchet sleeve 1, make it directed install, and the installation direction of plum blossom ratchet sleeve 1 can not be caused random or the troublesome operation such as will to aim at especially.
Described swingable parts in upwarping type, make plum blossom ratchet sleeve 1 and handle at an angle, operation time easy to use at the rear of rectangular opening.
Described latch-up structure is provided with elastomeric element, locating part, and described adjustable type quick change plum blossom ratchet torque spanner is also provided with the governor motion 6 of described elastomeric element, and described elastomeric element oppresses described locating part 52, makes described swingable parts keep its initial bit; Described governor motion is used for the pressure that adjustable elastic parts export to locating part, and described governor motion is provided with the regulating sleeve 6 be in outside handle 5.Described elastomeric element can adopt spring 50,
The rear end of described tilting member can arrange cam structure 51 bears locating part 52 pressure position as swingable parts.
When swingable parts outputting torsion exceedes setting value, the reaction force that swingable parts 41 bear is greater than the pressure that spring 50 exports, the cam structure 51 of swingable parts can jack-up locating part 5, swingable parts 3 swing instantaneously, clash into wall and produce click sound, prompting torsion exports and puts in place, can shut-down operation, avoids causing structural failure because operating force is excessive.
Described regulating sleeve is also provided with locking sleeve 7, and described locking sleeve 7, for lock adjustment cover 6, makes regulating sleeve can not rotate on handle.
Described governor motion is also provided with screw rod 90, and screw rod 90 is connected with regulating sleeve 6 by nut 91 and locking nut 92, and the rear end of elastomeric element described in pressing plate 9 fore-set is passed through in the front end of described screw rod 90.
The regulative mode that the utility model adjustable type quick change plum blossom ratchet torque spanner torsion exports size is as follows:
Described handle 5 is provided with some long chutes 53, and handle 5 surface is provided with torque value scale 8, and the front end of regulating sleeve 6 can be used to coordinate with scale 9, instruction torque value.Described regulating sleeve 6 front portion is provided with aperture 60, and aperture 60 can pass in and out for steel ball 61, throws off can make steel ball 61 and long chute 53.Locking sleeve spring 70 is provided with between described locking sleeve 7 and regulating sleeve, locking sleeve inwall then has the cam surface coordinated with steel ball 61, after pulling back locking sleeve 7, make to have steel ball 61 in locking sleeve to allow bit space, and remove the locking of locking sleeve to regulating sleeve, rotate regulating sleeve again, steel ball 61 and long chute 53 can be made to throw off, thus drive screw rod 90 rotate and regulate the pressure size to spring 50, now, along with the axial location change of regulating sleeve 6 on handle 5, and indicate current torque value.After adjusting, unclamp locking sleeve 7, the elastic force of locking sleeve spring 70 makes locking sleeve 7 reset, and steel ball 61 holds out against in long chute by locking sleeve 7, and lock adjustment cover 6, makes the setting value of torsion constant.
