Description
Technical field:
The utility model relates to the technical field of manual hardware & tools, specifically a kind of ratchet spanner.
Background technology:
Existing ratchet spanner utilizes the tooth of a ratchet to engage with swing pinion (or ratchet), and it is arranged in the opening of handle head, and ratchet can limit an opening be shaped.During use, the handle position that next time is afterburning from force to return is determined by the angle of hook tooth, and therefore usage space and angle are determined by the angle of hook tooth.When handle rotates, ratchet engages once with swing pinion (or ratchet), and the angle of rotation is the number of divisions of the tooth on handle head.In order in use, obtain less rotational angle, need the number of teeth increasing swing pinion (or ratchet), its requirement on machining accuracy is high, and production cost increases.
Summary of the invention:
The purpose of this utility model is the deficiency in order to overcome above-mentioned technology, and provide a kind of reasonable in design, structure is simple, easily manufactures, cost is low, easy to use, the ratchet spanner that operating efficiency is high.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of ratchet spanner, be provided with handle, square head, ratchet, ratchet stage clip, cover plate, jump ring, joint, steel ball, steel ball stage clip, square head is in the circular hole of handle head, cover plate is had at the two ends of handle head circular hole, by jump ring, square head is fixed in handle head circular hole, there is steel ball side at joint two ends, steel ball stage clip is had inside steel ball, one end of joint is connected with square head, in the arc groove of joint one end steel ball in the internal square hole of square head, it is characterized in that: in the circular hole of handle head, be evenly distributed with teeth groove, the calibration of each tooth is 12 °, square head is had in handle head circular hole, the lateral edge of square head there are two grooves, groove is distributed on two adjacent sides, two bottom portion of groove angle that line formed that is connected with square head center is respectively 90 °, ratchet stage clip is in groove walls, ratchet is arranged in two grooves in square head, the direction of two ratchets is identical, ratchet in square head is placed on the teeth groove in handle head circular hole.
The utility model is reasonable in design, and structure is simple, easily manufactures, and uses, easy to operate, time saving and energy saving, and can realize less corner, operating efficiency is high.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Mark in figure: 1, handle, 2, square head, 3, ratchet, 4, ratchet stage clip, 5, cover plate, 6, steel ball, 7, steel ball stage clip, 8, joint, 9, jump ring.
Detailed description of the invention:
As Fig. 1, shown in 2: a kind of ratchet spanner, be provided with handle 1, square head 2, ratchet 3, ratchet stage clip 4, cover plate 5, jump ring 9, joint 8, steel ball 6, steel ball stage clip 7, square head 2 is in the circular hole of handle 1 head, cover plate 5 is had at the two ends of handle 1 head circular hole, by jump ring 9, square head 2 is fixed in handle 1 head circular hole, there is steel ball 6 side at joint 8 two ends, steel ball stage clip 7 is had inside steel ball 6, one end of joint 8 is connected with square head 2, in the arc groove of joint 8 one end steel ball in the internal square hole of square head 2, teeth groove is evenly distributed with in the circular hole of its handle 1 head, the calibration of each tooth is 12 °, square head 2 is had in handle 1 head circular hole, the lateral edge of square head 2 there are two grooves, groove is distributed on two adjacent sides, two bottom portion of groove angle that line formed that is connected with square head 2 center is respectively 90 °, ratchet stage clip 4 is in groove walls, ratchet 3 is arranged in two grooves in square head 2, the direction of two ratchets 3 is identical, ratchet 3 in square head 2 is placed on the teeth groove in handle 1 head circular hole.
Equally distributed 30 teeth groove in handle 1 head circular hole, namely the calibration of each tooth is 12 °, square head 2 places ratchet 3 in two grooves, engaged with handle 1 head circular hole internal spline by ratchet 3, joint 8 is rotatable, and can only rotate to a direction, often rotating 6 ° just has a ratchet 3 to engage with teeth groove, can realize the function of 60 teeth groove like this; If when joint 8 needs to rotate in the opposite direction, the steel ball 6 of joint 8 other end is pushed in the arc groove of the internal square hole of square head 2, then the inverted use of ratchet spanner.
