With the rotator, the utility model can rotate the front body flexibly in operation, when cutting, a cutting connecting bar cuts a narrow spaced bar into equal sections, the positions of the cropper and the bar can be adjusted just by rotating the front body; compared with the prior art, the utility model is convenient to cut bars for users and improves the working efficiency.

Description

A kind of bar cropper

Technical field

The utility model relates to a kind of bar cropper.

Background technology

At first bar cropper adopts motor to drive grinding wheel by the V-belt mostly, adopting manually makes grinding wheel press down the cut-out reinforcing bar, but there is complex structure in this kind equipment, moulding is big, big and the grinding wheel of noise can produce the problems of spark when contacting with the reinforcing bar face, at these problems, the applicant has just applied for that on October 29th, 2004 patent No. is a kind of bar cropper of 200420112116.6, this patent disclosure the bar cropper volume little, in light weight, cut-off velocity is fast, no-spark, noiseless, solved the problems referred to above, brought positive result of use to users.But at dowel, when cutting off, because the space between the reinforcing bar is narrow and small, cutting machine is owing to can not rotate flexibly, when cutting off, just need to change the position of cutting off and cooperate the work of cutting off, sometimes even can not change the position of cutting machine and cause cutting off unsuccessful, or adopt other ways to enlarge space between reinforcing bars, cut off just very trouble and inconvenience of work like this, reduced operating efficiency; In addition because cutting machine of the prior art all is to adopt external power supply, if run into attaching plug with the operating position far the time, or there is not attaching plug, cutting machine just can't be worked, thereby existing bar cropper also need improve the demand that satisfies people.

Summary of the invention

In view of the existing deficiency of known technology, technical problem to be solved in the utility model provides and a kind ofly can rotate flexibly, the convenient dowel etc. of cutting off cuts off the narrow and small bar cropper in space, and this bar cropper also can operate as normal under the situation of no external power supply, is convenient to the user and waits in particular cases in outage and use.

In order to solve the problems of the technologies described above, the utility model is realized by following scheme: this kind bar cropper, include body, be provided with motor in the body, locating rack and hydraulic mechanism, body is provided with handle and the hand switch that is connected with motor, the eccentric wheel of described hydraulic mechanism and the turning cylinder of motor are in transmission connection, described locating rack is arranged on the front end of hydraulic mechanism, described locating rack is provided with ledger-plate, described hydraulic mechanism has the axle of cut-out, and the front end of this cut-out axle has cutting blade, and described ledger-plate matches when working with cutting blade, it is characterized in that described body be divided into before body with the back body, described before, back body connects by circulator.

Described circulator includes housing, spring and ball, and described housing is provided with aperture, and described spring and ball place in the aperture, and the end face that described preceding body contacts with ball is provided with at least two little grooves, and the position of this little groove is corresponding with ball.

Also have additional built-in power in the described body, the turning cylinder of described motor is connected with the deceleration internal gear.

The utility model has been installed circulator, the relative position of handle and locating rack can be changed, at dowel or cut off the narrow and small reinforcing bar in space, body changes the direction of locating rack before can directly rotating, make its position that turns to bar cutting, and the position of handle does not change, the user is keeping original posture to cut, make things convenient for user job, improved operating efficiency; The utility model built-in power under the situation that does not have attaching plug or outage, still can normally carry out work, and the deceleration internal gear has been saved the consumption of battery, has guaranteed the normal output speed of motor simultaneously in addition, makes cut-out work keep normal.The utility model has solved existing problem in the background technology, and is compared with prior art more practical, convenient, has substantive distinguishing features and progress.

Description of drawings

Further describe the relevant details of embodiment below in conjunction with accompanying drawing

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged drawing at the utility model Figure 1A place.

The specific embodiment

With reference to accompanying drawing, this kind bar cropper, body 5, back body 15 before including, described forward and backward body connects by circulator, this circulator can 360 ° of rotations, be provided with locating rack 1 and hydraulic mechanism 6 in the body 5 before described, be provided with motor 14 and built-in power 18 in the back body 15, this built-in power 18 can directly use battery or can use the mode of charging, the turning cylinder of described motor is connected with deceleration internal gear 13, the hand switch 16 that described back body 15 is provided with handle 17 and is electrically connected with motor.Described hydraulic mechanism 6 has axle of cut-out 4 and eccentric wheel 7, and described eccentric wheel 7 is in transmission connection with the turning cylinder of motor, and eccentric wheel 7 rotates and makes the cut-out axle 4 of hydraulic mechanism move.The described front end that cuts off axle 4 has cutting blade 3, and described locating rack 1 is provided with ledger-plate 2, and locating rack 1 is arranged on the front end of hydraulic mechanism 6, and ledger-plate 2 matches when working with cutting blade 3.Described circulator includes housing 10, spring 11 and ball 9, described housing 10 is provided with aperture 12, aperture 12 is two in the present embodiment, and two apertures are symmetrically distributed on the housing 10, corresponding spring 11 and ball 9 also are two, and described spring 11 places in the aperture 12 with ball 9, evenly are provided with four little grooves 8 on body 5 and the end face that ball 9 contacts before described, the position of this little groove 8 is corresponding with ball 9, and its degree of depth is less than the radius of ball.When utilizing the external force rotation, ball 9 is subjected to little groove 8 rim pressures to place the little groove of the interior disengaging of aperture until arriving next little groove, and spring 11 sets back, and ball places in the little groove 8 once more, thereby under the situation that not rotated by external force, forward and backward body can arbitrarily not rotate.

During the utility model work, during for dowel, body 5 before can rotating earlier makes locating rack 1 aim at reinforcing bar, after reinforcing bar is fixed, open hand switch 16 starter motors again, because built-in power voltage is big, thereby motor is transferred to the eccentric wheel 7 of hydraulic mechanism after deceleration internal gear 13 slows down, and eccentric wheel 7 rotates and makes the cut-out axle 4 of hydraulic mechanism move forward, cooperate with cutting blade 3 under the cutting at ledger-plate 2, the reinforcing bar on the locating rack 1 is cut off.Body 5 before can rotating once more as required after the cut-out makes locating rack 1 and reinforcing bar find suitable position, does not need to adjust whole cutting machine, and the user that is more convenient for uses, and has saved the adjustment time, has improved operating efficiency.
