Description of the Invention: TECHNICAL FIELD OF THE INVENTION The subject of the present invention is a novel manual bender. [Prior Art] In the prior art, 'a variety of types and configurations of pipe benders are known; among other examples, see EP 0484155, U1051854, and U1027314 (the latter being proposed by the applicant) 〇 Manual Benders are known to have even a ratchet mechanism; one of the unsolved problems of known benders is mentioned in, for example, U.S. Patent No. 5,048,567, the complexity of their structure and the operator's operation when operating them. Difficulty. Known benders are either operated electrically or hydraulically or require the use of both hands. SUMMARY OF THE INVENTION These problems can be overcome by the standard bender of the present invention; the operation is completely mechanical, The bending and unlocking operations only need to use one hand (the same hand). The standard bender of the present invention is constructed as a main support frame for a modular assembly; a rod is hinged to the main frame. It is characterized in that: a) the main frame comprises a support head of the mold assembly and a support grip of a ratchet, wherein the head and the grip have a -5-1378000 device which can be tightly fitted. The devices are a plurality of sets of connected rods/housings; b) the ratchet supports the bender and moves linearly relative to the grip and the head; the ratchet is provided with racks on opposite sides: c) having a one-way claw that engages/disengages the rack of the ratchet and is hinged to the rod; d) has a one-way pawl that engages/disengages the rack of the ratchet and is hinged To the grip; e) having at least one traction spring; the end of the spring is hooked on the grip and the ratchet, which can return the ratchet to an initial rest position, f) the bender and The mold assembly can be replaced by a quick engagement mechanism. In this basic concept, any embodiment that does not alter, change or modify the basics of the solution is included in the subject matter of the present invention. In order to more clearly understand the subject matter of the present invention, a preferred embodiment of the actual implementation is shown in the drawings, which can be performed in a minor modification that does not change its essence. [Embodiment] Practical, non-limiting examples of the invention. The pipe bender which is the subject of the present invention has a form which is constructed as a main frame, and the support die assembly (S): the main frame is hinged (A!) to one rod (5), and the unit has a similar See Figure 1 for the large-6-1378000 shape of a hand tool such as a tweezers or pliers. In accordance with the present invention, and in accordance with the illustrated embodiment, the main frame is provided with a head (11) that supports the die assembly (s) and a grip ('the grip carries the ratchet (3), The bender (C) is provided with a die assembly (S) and the bender (C) is replaceable by a quick engagement mechanism that will be added later. Head (11) and grip (12) Having a nestable device; in particular, a plurality of sets of rods (13) provided on one of the elements - the head (11) or the gripper _, which can be tightly fitted to the other One - in the connected housing in the head (11) or the grip (12) - see figure. In accordance with the present invention, and in accordance with the illustrated embodiment, it is provided with a (3) that can be guided relative to the grip (12) to linearly move the ratchet (3) on the opposite sides. a rack (3 1 ), (the bender (C) is mounted on the front end thereof, and a rear end is provided with a spring (4) for retracting the ratchet (3) to its initial position, In other words, the ends (41) and (42) are respectively on the hook body (1) and the ratchet wheel (3) itself - see Fig. 3. The same hinge (A2) on the grip (12) is a one-way push. The claw, whose teeth (6a) are operated by the rod (5) or the arm spring (61), respectively engages/disengages the rack (31) of the ratchet (3) - see figure. The set of rods (5) and one-way The claw (6) will return to the initial position of the stop/disengagement due to the traction spring (7). The traction spring is included! 12) 〇丨 to say: equal! (12' component, 6th ratcheting. 32) Stop at the end of this (6) and make the 3rd end of the 1378000 end (71) ' (72) hook to the main body and hinged shaft (A2) respectively. See Figure 3. Traction spring (4 ), (7) both are The cover portion (12a) attached to the grip (2) through, for example, a screw (121) is hidden from the line of sight - see Fig. 3. Less important and secondary to the efficacy of the present invention, the corresponding ends (41), (71) of the springs (4), (7) are mounted on the grip (12) as a spring ( 4), or install the cover (12a), as in the case of the spring (7), see Figure 3. Also less important and secondary to the efficacy of the invention is that the 'rod (5) is hinged (A!) to the grip (12) or to the lid (12a): as shown in Figure 3 In the embodiment, the rod (5) is hinged to the lid portion (12a). Further articulated (A3) on the grip (2) - a one-way pawl (2) whose teeth (2a) respectively engage/disengage the ratchet when operated by a push spring (21) or by the worker himself (3) Rack (32) - See Figure 3. The bent portion (S,) of the mold assembly (S) and the bent portion (C!) of the bender (C) are fixed and connected and different for each diameter of the tube to be bent. The mold assembly (S) and the bender (C) can be easily replaced by a quick engagement mechanism. The quick engagement mechanism is shown in Fig. 5, which is composed of the following in the illustrated embodiment. a bolt (T) in the (C) and the mold assembly (S), -8 - 1378000 ... the pin end (p) ' has a - coaxial spring (R); ~ in the head (11 There is a passage opening (〇|) having a channel (〇2) which is connected from the pin portion (P) and which is symmetrical in diameter and extends over the entire height thereof. In terms of construction, if it is to be assembled/disassembled, it is only necessary to insert the pin portion (p) into the channels and turn it 9 turns. So that it can be fixed by the action of the spring (r). BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an overall front view of a pipe bender of the present invention.
